Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a special plastic buckle for steel frames used in building construction. Background Technology

[0002] Building construction refers to the production activities during the implementation phase of an engineering project. It is the process of building various types of structures, or the process of turning the lines on design drawings into a physical object at a designated location. It includes foundation construction, main structure construction, roofing construction, and decoration construction.

[0003] Steel frames are frequently used in construction. They are used to build temporary support structures and serve as auxiliary structures to facilitate the overall construction of the project. Currently, the plastic clips for steel frames are basically fastened using simple diagonal clips. Since they are only secured by two bolts, if strong winds occur during construction, the bolts may loosen or crack, potentially causing significant economic losses or injuries to construction workers. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main purpose of this utility model is to provide a special plastic buckle for steel frames used in building construction.

[0005] The technical solution of this utility model is as follows: a special plastic buckle for steel frames in building construction, including an installation plate and installation screws. An installation nut is fixedly connected to the upper surface of the installation plate, and an installation box is fixedly connected to the lower surface of the installation plate. A sleeve is fixedly connected to the bottom wall of the installation box. A push rod is movably inserted into the upper surface of the sleeve. An opening is provided on the outer surface of the sleeve, and an arc-shaped pressure plate is slidably connected to the outer surface of the opening. A support base is fixedly connected to the bottom wall of the installation box, and an arc-shaped locking strip is rotatably connected to the support base. A locking seat is fixedly connected to the upper surface of the installation plate, and a rotating shaft is rotatably connected inside the locking seat. An elastic locking plate is fixedly sleeved on the outer surface of the rotating shaft.

[0006] As a preferred embodiment of a special plastic clip for steel frames used in building construction, the outer surface of the mounting screw is provided with a slot, and the slot is adapted to the arc-shaped clip.

[0007] In a preferred embodiment of a special plastic clip for steel frames used in building construction, a push block is fixedly connected to the bottom end of the mounting screw, and the push block is located directly above the push rod.

[0008] In a preferred embodiment of a special plastic buckle for steel frames used in building construction, a circular plate is fixedly connected to the bottom end of the push rod, a spring is fixedly connected between the circular plate and the sleeve, and the arc-shaped pressure plate is fixedly connected to the circular plate.

[0009] As a preferred embodiment of a special plastic clip for steel frames used in building construction, a magnetic block is fixedly connected to the outer surface of the arc-shaped clip, and a magnetic plate is fixedly connected to the inside of the mounting box. The magnetic block and the magnetic plate attract each other.

[0010] As a preferred embodiment of a special plastic clip for steel frames used in building construction, the elastic clip plate is made of elastic silicone, and the top of the elastic clip plate is set with an arc-shaped structure.

[0011] As a preferred embodiment of a special plastic buckle for steel frames used in building construction, a coil spring is fixedly connected between the elastic plate and the base, and the coil spring is sleeved on the outer surface of the rotating shaft.

[0012] In a preferred embodiment of a special plastic buckle for steel frames used in building construction, a limiting plate is fixedly connected to the outer surface of the buckle seat, and the limiting plate is located outside the elastic buckle plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by pushing the elastic plate outward, the handle on the mounting screw enters below the elastic plate. At this time, the elastic plate is released, and the elastic plate, through the reset action of the coil spring, squeezes the top of the mounting screw, thereby achieving a good fixing effect.

[0015] 2. In this utility model, when the mounting screw moves down, the pushing block at its bottom moves down and presses the push rod down. The push rod moves down and drives the circular plate to move down. The circular plate drives the arc-shaped pressure plate to move down. The arc-shaped moving plate drives the top of the arc-shaped locking strip to move towards the inside of the slot, thereby restricting the bottom of the mounting screw and preventing it from loosening due to stripping, thus achieving a good fixing effect.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1-4 A special plastic buckle for steel frames used in building construction includes an mounting plate 1 and mounting screws 2. The upper surface of the mounting plate 1 is fixedly connected to a mounting nut 3, the lower surface of the mounting plate 1 is fixedly connected to a mounting box 4, the bottom wall of the mounting box 4 is fixedly connected to a sleeve 7, the upper surface of the sleeve 7 is movably inserted with a push rod 8, the outer surface of the sleeve 7 has an opening 12, the outer surface of the opening 12 is slidably connected to an arc-shaped pressure plate 11, the bottom wall of the mounting box 4 is fixedly connected to a support base 13, and an arc-shaped locking strip 14 is rotatably connected to the support base 13.

[0023] Specifically, the outer surface of the mounting screw 2 is provided with a slot 5, which is compatible with the arc-shaped retaining strip 14. The bottom end of the mounting screw 2 is fixedly connected to a push block 6, which is located directly above the push rod 8. The bottom end of the push rod 8 is fixedly connected to a circular plate 9, and a spring 10 is fixedly connected between the circular plate 9 and the sleeve 7. The arc-shaped pressure plate 11 is fixedly connected to the circular plate 9. The outer surface of the arc-shaped retaining strip 14 is fixedly connected to a magnetic block 15, and the inside of the mounting box 4 is fixedly connected to a magnetic plate 16. The magnetic block 15 and the magnetic plate 16 attract each other, and the magnetic plate 16 can attract the magnetic block 15, so that the arc-shaped retaining strip 14 is located on the inner wall of the mounting box 4 without the action of external force.

[0024] Specifically, a card holder 17 is fixedly connected to the upper surface of the mounting plate 1. A rotating shaft 18 is rotatably connected inside the card holder 17. An elastic card plate 19 is fixedly sleeved on the outer surface of the rotating shaft 18. The elastic card plate 19 is made of elastic silicone and has an arc-shaped top. A coil spring 20 is fixedly connected between the elastic card plate 19 and the card holder 17. The coil spring 20 is sleeved on the outer surface of the rotating shaft 18 and can play a resetting role, so that the elastic card plate 19 can always be located above the mounting screw 2. A limiting plate 21 is fixedly connected to the outer surface of the card holder 17. The limiting plate 21 is located outside the elastic card plate 19 and can play a limiting role, thereby protecting the elastic card plate 19 and the coil spring 20.

[0025] Working principle: After connecting the mounting screw 2 and the mounting nut 3, the mounting screw 2 enters the mounting plate 1 and then the mounting box 4. When the mounting screw 2 rotates to the bottom, the elastic retaining plate 19 is pushed outward, and the handle on the mounting screw 2 enters below the elastic retaining plate 19. At this time, the elastic retaining plate 19 is released, and the elastic retaining plate 19, through the reset action of the coil spring 20, squeezes the top of the mounting screw 2, thereby achieving a good fixing effect. At the same time, when the mounting screw 2 moves down, the pushing block 6 at its bottom moves down, squeezing the push rod 8 downward. The push rod 8 moves down, causing the circular plate 9 to move down. The circular plate 9 moves the arc-shaped pressure plate 11 down, and the arc-shaped pressure plate 11 causes the top of the arc-shaped retaining strip 14 to move into the groove 5, thereby restricting the bottom of the mounting screw 2 and preventing it from loosening due to stripping, thus achieving a good fixing effect.
