Description

Technical Field

[0001] This utility model relates to the field of fixing screw technology, specifically a temporary fixing screw. Background Technology

[0002] Screws are tools that use the physical and mathematical principles of the inclined plane, circular rotation, and friction to gradually fasten objects and machine parts. When fixing some objects, it is necessary to use screws for fixation. The existing method is generally to fix them by drilling screw holes in the object. This method has the disadvantage of requiring screw holes to be drilled in the object. Another method is to fix the object by pressing it together with a screw and a square steel bar.

[0003] The existing method of fixing objects by pressing them together with screws and square steel is traditionally made of plastic, which is prone to deformation, low precision and easy damage. In addition, the position of the screw cannot be adjusted according to the shape of the object. Therefore, it is necessary to improve the existing fixing screws. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a temporary fixing screw, which solves the problem that fixing screws are not very effective.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a temporary fixing screw, comprising a square steel and a long screw rod, the bottom end of which penetrates the square steel and extends to the bottom of the square steel. A fixing box is located behind the long screw rod within the inner cavity of the square steel, and an arc-shaped plate is fixedly connected to the surface of the fixing box. The inner wall of the arc-shaped plate contacts the surface of the long screw rod. A clamping plate is located behind the square steel, and a pull rod is fixedly connected to the surface of the clamping plate. One end of the pull rod penetrates the square steel and the fixing box sequentially and extends to the inner cavity of the fixing box. A fixing plate is fixedly connected to the end of the pull rod extending into the inner cavity of the fixing box. A return spring is fixedly connected between the back of the fixing plate and the inner wall of the fixing box. Pressure rods are fixedly connected to both sides of the surface of the fixing plate. One end of the pressure rod penetrates the fixing box and extends to the outside of the fixing box, and the end of the pressure rod extending to the outside of the fixing box contacts the inner wall of the square steel.

[0006] Preferably, a gasket is provided on the top of the square steel, and the gasket is located on the surface of the long screw.

[0007] Preferably, the top and bottom of the square steel are provided with through slots that cooperate with the long screw.

[0008] Preferably, a slider is fixedly connected to the bottom of the fixed box, and a groove is provided at the bottom of the square steel inner cavity, with the surface of the slider slidably connected to the inner wall of the groove.

[0009] Preferably, the back of the square steel is provided with an opening for use with a tie rod.

[0010] Beneficial Effects: This utility model provides a temporary fixing screw. Compared with the prior art, it has the following beneficial effects: This temporary fixing screw, through one end of a pull rod, passes through the square steel and the fixing box in sequence and extends into the inner cavity of the fixing box. A fixing plate is fixedly connected to the end of the pull rod extending into the inner cavity of the fixing box. A return spring is fixedly connected between the back of the fixing plate and the inner wall of the fixing box. Pressure rods are fixedly connected to both sides of the surface of the fixing plate. One end of the pressure rod passes through the fixing box and extends to the outside of the fixing box. The end of the pressure rod extending to the outside of the fixing box contacts the inner wall of the square steel. The whole is made of metal, with high precision, and is not easily deformed after repeated use. It is also convenient to operate when the screw position needs to be adjusted. The position of the screw after adjustment can be limited to prevent shaking and ensure the fixing effect of the screw. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] See also Figures 1-3This utility model provides a technical solution: a temporary fixing screw, including a square steel 1 and a long screw 2. The bottom end of the long screw 2 penetrates through the square steel 1 and extends to the bottom of the square steel 1. A fixing box 3 is provided in the inner cavity of the square steel 1 behind the long screw 2, and an arc-shaped plate 4 is fixedly connected to the surface of the fixing box 3. The inner wall of the arc-shaped plate 4 is in contact with the surface of the long screw 2. A clamping plate 5 is provided behind the square steel 1, and a pull rod 6 is fixedly connected to the surface of the clamping plate 5. One end of the pull rod 6 passes through the square steel 1 and the fixing box 3 in sequence and extends... A fixing plate 7 is fixedly connected to one end of the pull rod 6 extending into the inner cavity of the fixing box 3. A return spring 8 is fixedly connected between the back of the fixing plate 7 and the inner wall of the fixing box 3. A pressure rod 9 is fixedly connected to both sides of the surface of the fixing plate 7. One end of the pressure rod 9 passes through the fixing box 3 and extends to the outside of the fixing box 3. The end of the pressure rod 9 extending to the outside of the fixing box 3 contacts the inner wall of the square steel 1. At the same time, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0017] Please see Figures 1-3 A gasket 10 is provided on the top of the square steel 1, and the gasket 10 is located on the surface of the long screw 2. The top and bottom of the square steel 1 are provided with through grooves 11 that cooperate with the long screw 2. A slider 12 is fixedly connected to the bottom of the fixed box 3. A sliding groove 13 is provided at the bottom of the inner cavity of the square steel 1. The surface of the slider 12 is slidably connected to the inner wall of the sliding groove 13. An opening for cooperation with the pull rod 6 is provided on the back of the square steel 1.

[0018] In use, the user places the object to be fixed at the bottom of the square steel 1, and then screws the long screw 2 into the fixing anchor point through the thread at the bottom. In this way, the object can be well fixed by the action of the long screw 2 and the square steel 1. Because some objects have different shapes, it is necessary to adjust the position of the long screw 2 on the square steel 1. At this time, the user can drive the pull rod 6 to move through the clamp 5, and then drive the pressure rod 9 to move through the fixing plate 7. When the pressure rod 9 moves away from the inner wall of the square steel 1, the user can adjust the position of the long screw 2. After adjustment, the clamp 5 is released. At this time, the elastic force accumulated by the return spring 8 will drive the clamp 5 to contact the back of the square steel 1, and the pressure rod 9 to contact the inner wall of the square steel 1, which can limit the position of the long screw 2 to a certain extent and prevent shaking.
