Technical Field

[0001] The present invention belongs to the technical field of fastening devices, and particularly relates to a screw quick connector and its disassembly component, which are widely used in various pipeline and electrical installations in the construction field and the automated integration field. Background Art

[0002] In the construction field and the automated integration field, screw and nut devices are commonly used connection methods for installing various pipelines and electrical accessories. In the traditional installation process, it is necessary to screw the screw into the nut preset in the pipeline and electrical frame and tighten it, which requires many turns to achieve the fastening purpose. Similarly, in the disassembly process, it also takes several turns to unscrew the screw, making it impossible to quickly complete tightening and disassembly, and unable to flexibly disassemble and use. Summary of the Invention

[0003] The purpose of the present invention is to design a screw quick connector and its disassembly component, which can realize the quick connection and disassembly of the quick connector and the screw, and at the same time meet the needs of pressing and flexible adjustment.

[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is as follows: The first object of the present invention proposes a screw quick connector, including a base, a clamping block is installed in the base, a screw passes through the middle of the base, and the clamping block presses on the external thread on the surface of the screw to achieve quick locking of the screw.

[0005] Further, the clamping block is installed on one side or both sides of the base, and the clamping block is pressed on the external thread on the surface of the screw through a torsion spring.

[0006] Further, the cross-section of the clamping block is in the shape of a "6", the front part in contact with the surface of the screw is the pressing part, a groove is provided in the middle of the rear part, and through holes are provided on both sides of the groove.

[0007] Further, the pressing part is designed in an arc shape, and the arc-shaped surface is provided with threads, which are correspondingly connected to the surface of the screw.

[0008] Further, through holes are provided on both sides of the base, a pin passes through the through holes of the base and the clamping block to install the clamping block in the base, and the torsion spring is sleeved on the pin and located in the groove of the clamping block.

[0009] Further, one end of the torsion spring abuts against or is connected to the clamping block, and the other end abuts against or is connected to the base.

[0010] Further, a section steel is installed outside the base.

[0011] The second object of the present invention proposes a disassembly component of the screw quick connector. The disassembly component is specifically a cylindrical tube body, and convex parts are provided on both sides of the top of the cylindrical tube body.

[0012] The following beneficial effects can be obtained through the above technical solutions: The present invention designs a screw fast connector, which can achieve the quick locking of the fast connector and the screw, and can be quickly disassembled by using a disassembly device. The fast connector includes components such as a base, a clamping block, a torsion spring, and a dowel pin. Through the elastic force of the torsion spring, the pressing part of the clamping block tightly presses against the surface of the threaded rod, playing a fastening role. Among them, the pressing part is designed in an arc shape, and its surface is threaded, so that the threads on the pressing part mesh with the thread teeth on the surface of the screw.

[0013] The overall structure of the present invention is simple, enabling the quick release and fastening between the fast connector and the screw, achieving flexible disassembly and fastening functions. Description of the Drawings

[0028] The following further describes the present invention with reference to the attached Figures 1-13 drawings.

[0029] Embodiment 1: As Figure 1 shown, a screw fast connector includes a base 2. The base 2 includes a bottom plate with a perforation. A connecting portion 22 extends downward from the perforation. The connecting portion is provided with an external thread structure, and a nut 1 is screwed thereon. Side plates are provided on the front and rear sides of the base 2. When viewed from the side, the base 2 is in a U-shaped groove shape. The left and right sides of the base are block placement grooves. At the same time, through holes are provided on the left and right sides of the side plates 21. The cross section of the block 8 is in a "6" shape or a whistle shape. The front part in contact with the screw surface is a pressing portion 81. A groove 83 is provided in the middle of the rear part. Through holes 82 are provided on both sides of the groove. During specific installation, the torsion spring 4 is placed into the groove 83 of the block. The column pin 5 passes through the through hole of the base, the through hole of the block, and the torsion spring 4. At the same time, one end of the torsion spring 4 abuts against the groove 83 of the block, and the other end abuts against the base. When the screw penetrates into the fast connector, the block is pressed against the external thread on the screw surface through the above structure to achieve rapid locking of the screw.

[0030] In the above embodiment, Figure 9 as shown, the pressing portion is designed to be arc-shaped, and threads are provided on the arc-shaped surface. Its structure corresponds to the external thread on the screw, so that the thread teeth are effectively engaged to achieve the purpose of locking.

[0031] Embodiment 2: Figure 10 As shown, a disassembly component 7 of a screw fast connector is a specific cylindrical tube body. Protruding portions 71 are provided on both sides of the top of the cylindrical tube body. The cross section of the protruding portion is trapezoidal. The top of the cylindrical tube body is designed as a step that rises in a stepped manner.

[0032] Figure 11 As shown, the disassembly component is inserted into the screw fast connector for rapid disassembly.

[0033] Figure 12 As shown is a structural relationship diagram of the screw 6 installed in the fast connector. Due to the elastic force of the torsion spring, the pressing portion 81 of the block firmly presses the screw, achieving an effect of firm fastening and locking.

[0034] When rapid disassembly is required, the specific method is as follows: Figure 13 As shown, the top of the disassembly component is sleeved from the bottom of the screw. The protruding portions on both sides of the top of the disassembly component contact the block. At this time, continue to push the disassembly component upward. The two protruding portions respectively jack up the two blocks, causing the two blocks to expand, so that the pressing portion 81 of the block is separated from the screw, and then the screw can be quickly pulled out.

[0035] The above are all preferred embodiments of the present invention. For those of ordinary skill in the art, without departing from the principle of the present invention, modifications to various equivalent forms of the present invention all fall within the protection scope of the appended claims of this application.
