Summary of information:We have more than ten years of production experience in the screw industry. The main products are: V-shaped rib bolts, e...

In all kinds of machines and equipment, the various parts are fixed and assembled by bolts and nuts. However, after the machine and equipment are used for a period of time, the bolts and nuts will become loose, which will bring great safety hazards to the use of the machine and equipment. For this reason, when bolts and nuts are used for connection, a spring washer is installed between the nut and the connected part. The spring washer is in the shape of a circular ring, and the ring is not closed, and is sleeved on the bolt. The addition of the spring washer has a certain anti-loosening effect, but it can only prevent the nut from rotating relative to the bolt. In the case of large vibration of the machine, the bolt will rotate relative to the connected part.

As a commonly used data communication device, connectors are widely used in computers and TVs. Because common connectors such as D-SUB and DVI are composed of a male seat and a female seat, the iron shell of the male seat and the female seat is The corresponding position is provided with holes, the holes of the male seat are connected with rivets, and the holes of the female seat are correspondingly provided with screws for fixing. After the male seat and the female seat are connected, tighten the screws so that the male seat and the female seat are tightly connected together. When assembling on a computer or a TV, the rivet has a fixed assembly direction, and the fixation of the rivet direction is very important for assembly. However, there is no anti-rotation device on the iron shell hole connected with the rivet on the existing connector, and the rivet cannot be positioned during the assembly process, and it is easy to rotate and dislocate. production efficiency.

The hinge is a hinge, which is often composed of two folds. It is a part that connects the two parts of the object and can make it move. The hinge supporting screws are installed on the corresponding objects. For different use environments, the requirements for the supporting screws are also different. different. Most of the existing screws are set to a single-threaded structure. When used to cut into a wooden door, the cutting speed is slow, and the cutting effect is not ideal, which is not conducive to cutting into a hard wooden door, etc., and the commonly used screws are often made of iron materials. It is easy to rust after contact with water vapor, reducing the service life; in addition, when the screw is driven into the wooden door, the chips generated cannot be discharged in time, and stay inside the wooden door and surround the screw, forming expansion stress, thereby squeezing the wooden substrate, which is not conducive to the screw. The connection with the wooden door is stable, which easily affects the normal installation of the hinge, and the use effect is poor. To sum up, in order to solve the shortcomings of the existing screw structure for hinges, Guangdong Yueluo Hardware Industry Co., Ltd. designed a hinge screw with simple structure, convenient use, fast construction and good effect.

door cover structure with hidden screws includes a glass panel, an inner door cover, a computer board and a sealing strip, an adhesive bracket is adhered to the back of the glass panel, the inner door cover is fixedly connected with the adhesive bracket through screws, and the computer board is arranged on the glass panel. In the cavity formed by the panel and the inner door cover, the inner door cover is provided with a sealing slot, the sealing strip is embedded in the sealing slot, and the bottom of the sealing slot is provided with a mounting hole for the screw to pass through, and the glue The bracket is provided with a fixing hole matched with a screw thread, and the screw passes through the installation hole of the inner door cover and is threadedly connected with the fixing hole of the adhesive bracket, so as to fixedly connect the inner door cover and the glass panel. The screw is hidden in the sealing groove of the door cover, and is sealed with water through the sealing strip. The appearance is beautiful, easy to disassemble and assemble, and it can effectively protect the screw from rust.

The diameter, length and quantity of the stud bolts shall meet the requirements, and the type and material of the stud bolts shall be determined by the grade. There are two types of commonly used stud bolts (also known as full-threaded studs). The thread is divided into two types: coarse thread and fine thread. The coarse thread ordinary thread is expressed by M and the nominal diameter, and the fine thread ordinary thread is expressed by M and the nominal diameter × pitch. The fastener standard stipulates that M36 bolts use coarse thread, M36 and above diameters can use fine thread, and the pitch is 3. bm=1d studs are generally used for the connection between two steel connected parts; bm=1.25d and bm=1.5d studs are generally used between cast iron connected parts and steel connected parts The connection between the two; bm=2d double-ended stud is generally used for the connection between the aluminum alloy to be connected and the steel to be connected. The former connector has internal threaded holes, and the latter connector has through holes. The threads at both ends of the equal-length studs need to be matched with nuts and washers, and are used for two connected parts with through holes. One end of the welding stud is welded on the surface of the connected piece, and the other end (threaded end) passes through the connected piece with a through hole, and then the washer is put on, and the nut is screwed on, so that the two connected pieces are connected as a whole.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: thin head bolts, screws with holes, GB118 internal thread pins, hexagonal belt nuts and other products, we can provide you with suitable fasteners solution.
