Description

Technical Field

[0001] This utility model relates to the field of train dismantling tools, and in particular to a double-section talon-type cotter pin removal hook that is easy to assemble. Background Art

[0002] Currently, there are many and varied tools for dismantling trains, which need to be used in combination. Workers need to carry 8-10 kinds of tools when carrying out dismantling operations. If a certain tool is missing, the operation may not be able to be carried out, and the safety of the workers during the operation cannot be guaranteed.

[0003] Since there are as many as 16 types of pins on trains, and different pins require different tools to remove, workers have to carry a large number of tools before starting work. Common tools cannot remove pins quickly and safely, resulting in workers having to carry a large number of tools, long working hours, low safety factor, and easy accidents. To solve the above problems, we propose a double-section talon-type cotter pin removal hook that is easy to assemble. Utility Model Content

[0004] The purpose of this invention is to provide a double-section talon-type cotter pin removal hook that is easy to assemble, so as to solve the problems mentioned in the background art.

A first section is fixedly connected to the right side of the connecting block. A second section is fixedly connected to the right end of the first section. A third section is fixedly connected to the right end of the second section. A fourth section is fixedly connected to the right end of the third section. A positioning groove is formed on the right side of the connecting seat. A positioning block is fixedly connected to the left side of the connecting block. A groove is formed on the left side of the connecting seat.

[0007] In a further embodiment, the left end of the positioning block extends into the interior of the positioning groove, and the outer surface of the positioning block contacts the inner wall of the positioning groove.

[0008] In a further embodiment, the inner wall of the positioning groove is provided with a through hole, and a fixing screw is fixedly connected to the left side of the positioning block. The left end of the fixing screw passes through the through hole and extends into the interior of the groove.

[0009] In a further embodiment, the inner wall of the groove is threaded, and a threaded connecting ring is threadedly connected to the inner wall of the groove. A sealing plate is fixedly connected to the left side of the threaded connecting ring.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This utility model features a four-fold falcon-inspired hook that can be adapted to 16 types of cotter pins used on trains. Its unique curvature provides strong load-bearing capacity and excellent locking performance, ensuring stable and safe connections during disassembly and preventing the cotter pin from flying off the moment it is removed. The falcon-inspired hook is made of 40Cr material, balancing strength and toughness, and can withstand large loads while maintaining structural stability and safety. Through the design of the connecting seat and connecting block, and in conjunction with the positioning block and positioning groove, the connecting seat and hook assembly can be flexibly combined and installed, improving the flexibility of use.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 In this utility model, a double-segment talon-type cotter pin removal hook that is easy to assemble includes a connecting seat 1. A connecting block 2 is provided on the right side of the connecting seat 1. A first segment 3 is fixedly connected to the right side of the connecting block 2. A second segment 4 is fixedly connected to the right end of the first segment 3. A third segment 5 is fixedly connected to the right end of the second segment 4. A fourth segment 6 is fixedly connected to the right end of the third segment 5. A positioning groove 7 is provided on the right side of the connecting seat 1. A positioning block 8 is fixedly connected to the left side of the connecting block 2. A groove 14 is provided on the left side of the connecting seat 1. Through the arrangement of the connecting seat 1 and the connecting block 2, and their cooperation with the positioning block 8 and the positioning groove 7, the connecting seat 1 and the hook assembly can be flexibly disassembled and installed, improving the flexibility during disassembly and assembly.

[0023] In a further embodiment, the left end of the positioning block 8 extends into the interior of the positioning groove 7, and the outer surface of the positioning block 8 contacts the inner wall of the positioning groove 7. A through hole 9 is provided in the inner wall of the positioning groove 7. A fixing screw 10 is fixedly connected to the left side of the positioning block 8. The left end of the fixing screw 10 passes through the through hole 9 and extends into the interior of the groove 14. A fixing nut 11 is threadedly connected to the outer surface of the fixing screw 10. The right end of the fixing nut 11 contacts the inner wall of the groove 14. By setting the fixing screw 10 and the through hole 9, and cooperating with the fixing nut 11, the positioning block 8 inside the positioning groove 7 can be locked and fixed, which will make the positioning block 8 more secure. At the same time, the hook assembly can be flexibly disassembled and replaced, achieving the effect of easy assembly.

[0024] In a further embodiment, the inner wall of the groove 14 is threaded, and a threaded connecting ring 13 is threadedly connected to the inner wall of the groove 14. A sealing plate 12 is fixedly connected to the left side of the threaded connecting ring 13. The bending angle of the first segment 3 is 45°, the bending angle of the second segment 4 is 135°, the bending angle of the third segment 5 is 135°, and the bending angle of the fourth segment 6 is 90°. By setting the threaded connecting ring 13, the sealing plate 12 can be installed at the left end of the connecting seat 1, thereby sealing the groove 14 on the left side of the connecting seat 1.

[0025] The working principle of this utility model is as follows: First, the connection between the pin remover and the pin hole adopts a falcon-inspired bionic structure, made of 40Cr material, with four-segment bending. The bending points are designed with rounded corners to improve structural strength and reduce stress concentration. All bends are multiples of 45°. In the field of metal processing, 45° angle cutting is used for cutting and processing various metal materials. By using 45° angle cutting, a smooth cutting surface can be obtained, improving the strength of metal components. The first segment 3 is bent at a 45° angle, the second segment 4 at a 135° angle, the third segment 5 at a 135° angle, and the fourth segment 6 at a 90° angle.

[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0027] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
