Technical Field

[0001] The invention relates to the field of pin shafts, in particular to a high-stability pin shaft that is easy to install and disassemble. Background Art

[0002] In the field of mechanical connection, pins are a common connector widely used in various equipment and structures. However, traditional pins often have many inconveniences during installation and removal, such as difficult installation, cumbersome disassembly, and insufficient stability. These problems are particularly prominent in situations where frequent replacement or maintenance is required.

[0003] In order to solve the above problems, some improved pins have appeared on the market, but these pins still have some defects in design. For example, although some pins have added anti-dropout structures, the anti-dropout effect is not ideal and they are easy to loosen or fall off when subjected to force or vibration. Other pins have problems such as complicated installation process and difficult disassembly, which brings great inconvenience to use and maintenance.

[0004] Therefore, the present invention proposes a high-stability pin shaft that is easy to install and disassemble, aiming to solve the problems of the existing pin shaft in installation, disassembly and stability, and improve the use efficiency and safety of the pin shaft.

[0007] Preferably, a rubber strip is fixed on the rod body of the baffle bar, the rubber strip is an arc-shaped strip, two rubber strips are provided, and after the baffle bar is inserted into the reserved hole, the two rubber strips are located at the upper and lower sides of the pin shaft body.

[0008] Preferably, the side groove is a square groove, a limiting axis is fixed between two parallel side walls of the side groove, the limiting axis passes through a through hole, the through hole is provided on the surface of the traction handle, and the thickness of the traction handle is smaller than the depth of the side groove.

[0009] Preferably, the elastic hanging piece is perpendicular to the traction handle, and the thickness of the traction handle plus the plate width of the elastic hanging piece is smaller than the depth of the side groove.

[0010] Preferably, the clamping strip is a right-angle trapezoidal strip, a pull ring is fixed on the surface of the elastic hanging piece, the pull ring and the clamping strip are symmetrically distributed about the elastic hanging piece, and the right-angle height of the elastic hanging piece is smaller than the height of the clamping slot.

[0011] Preferably, both sides of the traction handle are provided with embedding grooves, and rubber clamping strips are fixed inside the embedding grooves, and the thickness of the rubber clamping strips is greater than the depth of the embedding grooves.

[0012] Preferably, after the traction handle is pushed into the side groove, the rubber clamp strip is clamped between the traction handle and the side groove to generate elastic deformation.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The high-stability pin shaft that is easy to install and disassemble proposed by the present invention makes the installation and disassembly process of the pin shaft simple and quick by designing the plug-in structure of the reserved hole and the baffle bar, as well as the rotation of the traction handle and the clamping structure of the clamping strip. The user only needs to pass the pin shaft body through the workpiece, then insert the baffle bar and rotate the traction handle to achieve a stable connection of the pin shaft.

The clamping strip is clamped in the clamping groove, which further strengthens the connection stability of the baffle bar. This double anti-slip structure makes the pin shaft not easy to loosen or fall off when subjected to force or vibration, thereby improving the safety and reliability of the connection.

DETAILED DESCRIPTION

[0025] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 9 The present invention provides a technical solution: a high-stability pin shaft that is easy to install and disassemble, including a pin shaft body 1, a reserved hole 2 is opened on the surface of the pin shaft body 1, a baffle 3 is inserted into the reserved hole 2, a rubber strip 4 is fixed on the rod body of the baffle 3, the rubber strip 4 is an arc-shaped strip, and two rubber strips 4 are provided. After the baffle 3 is inserted into the reserved hole 2, the two rubber strips 4 are located on the upper and lower sides of the pin shaft body 1.

[0027] When in use, after the pin shaft body 1 passes through the workpiece that needs to be penetrated, the blocking strip 3 is inserted into the reserved hole 2, the blocking strip 3 passes through the reserved hole 2, and the exposed length of both ends of the blocking strip 3 is sufficient to allow the two rubber strips 4 to be at the notches at both ends of the reserved hole 2, that is, the rubber strips 4 are blocked at the notches of the reserved hole 2, thereby realizing the anti-slip limit function of the blocking strip 3.

[0028] Both ends of the baffle 3 are provided with side grooves 5, and a traction handle 8 is rotatably connected inside the side groove 5. The side groove 5 is a square groove, and a limiting axis 6 is fixed between two parallel side walls of the side groove 5. The limiting axis 6 passes through a through hole 7, and the through hole 7 is provided on the surface of the traction handle 8. The thickness of the traction handle 8 is less than the depth of the side groove 5. An elastic hanging piece 9 is fixed on the surface of the traction handle 8. The elastic hanging piece 9 is perpendicular to the traction handle 8. The thickness of the traction handle 8 plus the plate width of the elastic hanging piece 9 is less than the depth of the side groove 5. A clamping strip 10 is fixed on the surface of the elastic hanging piece 9. When the traction handle 8 is placed flat on the pin shaft body 1, the clamping strip 10 is inserted into the clamping slot 11, and the clamping slot 11 is provided at one end of the pin shaft body 1; the clamping strip 10 is a right-angled trapezoidal strip, and a pull ring 12 is fixed on the surface of the elastic hanging piece 9. The pull ring 12 and the clamping strip 10 are symmetrically distributed about the elastic hanging piece 9, and the right-angle height of the elastic hanging piece 9 is less than the height of the clamping slot 11.

[0029] When in use, in order to reinforce the anti-slip limit after the baffle bar 3 is inserted into the reserved hole 2, the traction handle 8 is pulled out from the side groove 5, and the traction handle 8 is turned to rotate with the limit shaft 6 as the center axis. After the traction handle 8 is tilted and overlapped on the rod body of the pin shaft body 1, the traction handle 8 is continued to be squeezed and pushed until the clamping bar 10 is inserted into the clamping groove 11. In this way, the traction handles 8 at both ends of the baffle bar 3 are adjusted to the corresponding clamping bar 10 inserted into the corresponding clamping groove 11, thereby realizing the anti-slip limit of the baffle bar 3.

[0030] Both sides of the traction handle 8 are provided with an embedding groove 13, and a rubber clamp 14 is fixed inside the embedding groove 13, and the thickness of the rubber clamp 14 is greater than the depth of the embedding groove 13; after the traction handle 8 is pushed into the side groove 5, the rubber clamp 14 is clamped between the traction handle 8 and the side groove 5 to generate elastic deformation; when the traction handle 8 is retracted into the side groove 5, it will not affect the traction handle 8 from being withdrawn from the through hole 7, and the rubber clamp 14 is clamped between the traction handle 8 and the side groove 5, increasing the friction between the traction handle 8 and the side groove 5, and preventing the traction handle 8 from swinging out of the side groove 5 at will.

[0031] The process of using the high-stability pin that is easy to install and disassemble is as follows:

[0032] Make sure the workpiece to be penetrated is ready and determine the position where the pin body 1 needs to pass through. Check whether the pin body 1, the reserved hole 2, the stop bar 3 and its related parts are intact and whether the rubber strip 4 is in good condition.

[0033] Pass the pin body 1 through the workpiece that needs to be penetrated, and ensure that the pin body 1 can pass through smoothly and is in the correct position. Insert the baffle 3 into the reserved hole 2, and ensure that the baffle 3 can completely penetrate the reserved hole 2. Adjust the position of the baffle 3 so that the two rubber strips 4 are respectively located on the upper and lower sides of the pin body 1 to achieve preliminary positioning of the baffle 3. Pull out the traction handle 8: Pull out the traction handle 8 from the side groove 5 to ensure that the traction handle 8 can rotate freely. With the limiting shaft 6 as the center axis, rotate the traction handle 8 so that it tilts and overlaps the rod body of the pin body 1. Continue to push the traction handle 8 until the card strip 10 is fully inserted into the card slot 11 to achieve further anti-slip positioning of the baffle 3. Adjust the traction handles 8 at both ends of the baffle 3 according to the above steps until the corresponding card strips 10 are inserted into the corresponding card slots 11.

[0034] Confirm whether the blocking bar 3 and its traction handle 8, the clamping bar 10 and other components are installed in place and whether the pin body 1 is firmly limited. Check whether the rubber strip 4 and the rubber clamping strip 14 are in a good elastic state and can effectively provide friction and limiting effects.

[0035] After confirming that the installation is correct, the pin can be used normally for connection or fixing operations. During use, regularly check the status of the pin and its related parts to ensure that they are in good working condition. If necessary, clean, lubricate or replace the pin and its related parts to extend its service life.

[0036] When the pin needs to be disassembled, first release the limiting effect of the traction handle 8 and the clamping strip 10 on the blocking bar 3. Pull out the blocking bar 3 from the reserved hole 2 to ensure that the pin body 1 can be smoothly pulled out of the workpiece. Arrange and store the disassembled pin and its related components for next use. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
