Description

Technical Field

[0001] This utility model relates to the field of mechanical parts, specifically to a shaft pin that is easy to insert. Background Technology

[0002] As a common part in the field of mechanical connection, the shaft pin is widely used in the articulation, positioning and transmission scenarios of various mechanical equipment. It mainly realizes the relative rotation or axial positioning function between components by cooperating with the pin hole. Traditional shaft pins are usually an integral cylindrical structure, which is fixed to the associated components by means of interference fit, threaded connection or cotter pin to ensure the reliability of the connection.

[0003] Currently, in actual production and assembly processes, the insertion and removal of traditional shaft pins often presents many inconveniences. On the one hand, when equipment needs maintenance, replacement of parts, or debugging, the installation and removal of shaft pins often rely on tools, which not only involves cumbersome operation steps and is time-consuming, but may also cause damage to the shaft pin or related parts due to improper tool operation. On the other hand, for some usage scenarios that require frequent insertion and removal of shaft pins, the efficiency of traditional shaft pin installation and removal affects the overall operating efficiency of the equipment and increases labor and time costs.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a shaft pin that is easy to insert, thereby solving the problems of poor adaptability of traditional shaft pins to components of different thicknesses and cumbersome operation of fixing and separating cotter pins.

[0006] The technical solution adopted by this application to solve its technical problem is as follows: a shaft pin that is easy to insert, including a shaft pin and an adjusting member installed in the inner cavity of one side of the shaft pin. An adjusting seat is threadedly connected to the outer side of the adjusting member. Through the threaded engagement between the adjusting member and the adjusting seat, it can adapt to the parts to be connected with different thicknesses, making the insertion applicability of the shaft pin wider. The adjusting seat is slidably connected to the shaft pin. An elastic retainer is slidably installed in the inner cavity of the adjusting seat. An adsorption member is installed at the lower end of the elastic retainer. The elastic retainer and the adjusting seat attract each other through the adsorption member. The elastic retainer, together with the adsorption member and the adjusting seat, have a magnetic positioning effect to prevent the elastic retainer from failing to maintain the clamping working position due to inversion. A cotter pin is inserted into the inside of the adjusting seat. The cotter pin engages with the elastic retainer to fix and lock the shaft pin in position.

[0007] Furthermore, the pin component includes a pin body and a movable hole that extends through the pin body, and a limiting groove is formed on one side of the inner cavity of the pin body.

[0008] Furthermore, the adjusting component includes an adjusting screw and an adjusting block fixedly installed at one end of the adjusting screw. The adjusting screw is rotatably connected to the shaft pin body, and the adjusting block is configured to rotate the adjusting screw, thereby driving the adjusting seat to adjust the spacing.

[0009] Furthermore, the adjusting seat includes a fixed shell and fixed holes extending through both sides of the fixed shell. A magnet placement cavity is provided at the lower end of the fixed shell. An adjusting block is fixedly installed on one side of the fixed shell. The adjusting block is slidably connected to the shaft pin body. A threaded hole is provided through one side of the adjusting block. An adjusting screw is threadedly connected to the threaded hole. A fixed plate is fixedly installed on one side of the fixed shell. A limit post is fixedly installed on one side of the fixed plate. The limit post is slidably connected to a limit groove. The limit post is slidably engaged with the limit groove in the inner cavity of the shaft pin body to limit the movement trajectory of the adjusting seat.

[0010] Furthermore, an inclined groove is provided inside the fixed shell, which is used for sliding connection with the elastic card seat.

[0011] Furthermore, the elastic card holder includes a card holder block and a cylindrical block slidably connected to one side of the card holder block. Rectangular guide blocks are fixedly installed at both ends of the card holder block. The rectangular guide blocks are slidably installed in the inclined groove. The rectangular guide blocks cooperate with the inclined groove to guide the direction and prevent the elastic card holder from rotating. A baffle is fixedly installed on one side of the card holder block. Two round holes are opened through one side of the baffle. A spring is fixedly installed on one side of the card holder block, and one end of the spring extends out of the baffle through the round holes. A clamping block is fixedly installed at one end of the cylindrical block. The clamping block is used to clamp a cotter pin. A magnet placement groove is opened at the lower end of the card holder block. The magnet placement groove is used to place an adsorption component.

[0012] Furthermore, the adsorption component includes a first magnet and a second magnet. The first magnet is installed in the magnet placement cavity at the lower end of the fixed shell, and the second magnet is installed in the magnet placement slot. The first magnet and the second magnet generate an adsorption force. The magnetic force of the adsorption of the first magnet and the second magnet allows the shaft pin to still work normally after being inverted. The first magnet and the second magnet are arranged opposite each other, and the magnetic attraction between them is sufficient to overcome the gravity of the elastic seat when the shaft pin is inverted, so that it is kept in the initial working position in the fixed shell.

[0013] Furthermore, two clamping grooves are provided on both sides of the cotter pin. The clamping blocks are used to clamp the clamping grooves and fix the position of the cotter pin. When the cotter pin is inserted into the elastic seat, the clamping blocks on both sides will move inward with the help of the spring. The cylindrical block limits the movement of the clamping blocks. When it falls to the position of the clamping groove, the clamping block will be inserted into the clamping groove to clamp and limit the cotter pin. When it moves upward, the clamping block will drive the elastic seat and the rectangular guide block to open along the direction of the inclined groove due to the upward force, so as to realize the rapid separation of the cotter pin and the elastic seat.

[0014] The beneficial effects of this application are: the shaft pin provided by this application is easy to insert, and through the threaded engagement of the adjusting part and the adjusting seat, it can be adapted to the parts to be connected of different thicknesses, effectively improving the applicability of shaft pin insertion and broadening its application scenarios.

[0015] By engaging the cotter pin with the elastic seat, the clamping block is quickly fixed by being engaged in the clamping groove under the action of the spring when inserted. When moving upward, the clamping block drives the elastic seat to separate along the inclined groove to achieve quick disassembly, thereby improving the efficiency of installing and disassembling the shaft pin.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] like Figure 1 As shown, the device includes a shaft pin 1 and an adjusting member 2 installed in the inner cavity of one side of the shaft pin 1. An adjusting seat 3 is threadedly connected to the outer side of the adjusting member 2. Through the threaded engagement between the adjusting member 2 and the adjusting seat 3, it can adapt to the components to be connected with different thicknesses, making the shaft pin more versatile. The adjusting seat 3 is slidably connected to the shaft pin 1. An elastic retainer 4 is slidably installed in the inner cavity of the adjusting seat 3. An adsorption member 5 is installed at the lower end of the elastic retainer 4. The elastic retainer 4 attracts the adjusting seat 3 through the adsorption member 5. The elastic retainer 4, together with the adsorption member 5, magnetically positions the adjusting seat 3, preventing the elastic retainer 4 from failing to maintain the clamping working position due to inversion. A cotter pin 6 is inserted into the inside of the adjusting seat 3. The cotter pin 6 engages with the elastic retainer 4 to fix and lock the shaft pin 1 in position.

[0028] like Figure 2 As shown, the pin component 1 includes a pin body 11 and a movable hole 12 that passes through the inside of the pin body 11. A limiting groove 13 is formed on one side of the inner cavity of the pin body 11.

[0029] like Figure 3 As shown, the adjusting component 2 includes an adjusting screw 21 and an adjusting block 22 fixedly installed at one end of the adjusting screw 21. The adjusting screw 21 is rotatably connected to the shaft pin body 11. The adjusting block 22 is set to make the adjusting screw 21 rotate, thereby driving the adjusting seat 3 to adjust the spacing.

[0030] like Figure 3As shown, the adjusting seat 3 includes a fixed shell 31 and fixed holes 32 that penetrate through both sides of the fixed shell 31. A magnet placement cavity is provided at the lower end of the fixed shell 31. An adjusting block 33 is fixedly installed on one side of the fixed shell 31. The adjusting block 33 is slidably connected to the shaft pin body 11. A threaded hole 34 is provided through one side of the adjusting block 33. The adjusting screw 21 is threadedly connected to the threaded hole 34. A fixing plate 35 is fixedly installed on one side of the fixed shell 31. A limiting post 36 is fixedly installed on one side of the fixing plate 35. The limiting post 36 is slidably connected to the limiting groove 13. The limiting post 36 is slidably engaged with the limiting groove 13 in the inner cavity of the shaft pin body 11 to limit the movement trajectory of the adjusting seat 3.

[0031] In this application, the adjusting screw 21 of the adjusting component 2 and the adjusting block 22 and the threaded hole 34 on the adjusting block 33 of the adjusting seat 3 are used together to make the adjusting block 22 drive the adjusting screw 21 to rotate. The adjusting screw 21 is threadedly connected to the threaded hole 34, which drives the adjusting seat 3 to slide through the adjusting block 33 and the shaft pin body 11 of the shaft pin component 1 to adjust the spacing to adapt to the components to be connected with different thicknesses. The upper limit post 36 of the fixing plate 35 of the adjusting seat 3 slides with the limiting groove 13 of the shaft pin body 11 to limit the movement trajectory of the adjusting seat 3.

[0032] like Figures 4-5 As shown, an inclined groove 311 is provided inside the fixed shell 31, and the inclined groove 311 is provided for sliding connection with the elastic card seat 4.

[0033] like Figures 4-5 As shown, the elastic card holder 4 includes a card holder block 41 and a cylindrical block 42 slidably connected to one side of the card holder block 41. Rectangular guide blocks 43 are fixedly installed at both ends of the card holder block 41. The rectangular guide blocks 43 are slidably installed in the inclined groove 311. The rectangular guide blocks 43 cooperate with the inclined groove 311 to guide the direction and prevent the elastic card holder 4 from rotating. A baffle 44 is fixedly installed on one side of the card holder block 41. Two round holes 45 are opened through one side of the baffle 44. A spring 46 is fixedly installed on one side of the card holder block 41, and one end of the spring 46 extends out of one side of the baffle 44 through the round holes 45. A clamping block 47 is fixedly installed at one end of the cylindrical block 42. The clamping block 47 is used to clamp the cotter pin 6. A magnet placement groove 48 is opened at the lower end of the card holder block 41. The magnet placement groove 48 is used to place the adsorption component 5.

[0034] like Figures 4-5As shown, the adsorption component 5 includes a first magnet 51 and a second magnet 52. The first magnet 51 is installed in the magnet placement cavity at the lower end of the fixed shell 31, and the second magnet 52 is installed in the magnet placement groove 48. The first magnet 51 and the second magnet 52 generate an adsorption force. The magnetic force of the adsorption of the first magnet 51 and the second magnet 52 can enable the shaft pin to still work normally after being inverted. The first magnet 51 and the second magnet 52 are arranged opposite to each other, and the magnetic attraction between them is sufficient to overcome the gravity of the elastic card seat 4 when the shaft pin is inverted, so that it is kept in the initial working position in the fixed shell 31.

[0035] like Figures 2-3 As shown, two clamping grooves 61 are provided on both sides of the cotter pin 6. The clamping blocks 47 are set to clamp the clamping grooves 61 and fix the position of the cotter pin 6. When the cotter pin 6 is inserted into the elastic card seat 4, the clamping blocks 47 on both sides will move inward with the cooperation of the spring 46. The cylindrical block 42 limits the movement of the clamping blocks 47. When it falls to the position of the clamping groove 61, the clamping blocks 47 will be inserted into the clamping groove 61 to clamp and limit the cotter pin 6. When it moves upward, the clamping blocks 47 will drive the elastic card seat 4 and the rectangular guide block 43 to open along the direction of the inclined groove 311 due to the upward force, so as to realize the rapid separation of the cotter pin 6 from the elastic card seat 4.

[0036] In this application, the inclined groove 311 of the fixed shell 31 cooperates with the rectangular guide blocks 43 at both ends of the retaining block 41 of the elastic retaining base 4 to guide the direction of the elastic retaining base 4 and prevent its rotation. The spring 46 on one side of the retaining block 41 cooperates with the cylindrical block 42 and the clamping block 47. The baffle 44 limits the retraction distance of the clamping block 47. The first magnet 51 and the second magnet 52 of the adsorption member 5 keep the elastic retaining base 4 in its working position within the fixed shell 31, ensuring the shaft pin can work normally. The opening... The clamping groove 61 of the pin 6 and the clamping block 47 of the elastic card seat 4 work together. When the cotter pin 6 is inserted, the clamping blocks 47 on both sides move inward under the action of the spring 46. The cylindrical block 42 limits its movement. When the clamping block 47 falls to the clamping position, it is locked into the clamping groove 61, thereby clamping and fixing the cotter pin 6. When the cotter pin 6 moves upward, the clamping block 47 is driven by the upward force to slide and separate the elastic card seat 4 and the rectangular guide block 43 along the inclined groove 311 of the fixed shell 31, thereby realizing the quick assembly and disassembly of the cotter pin 6 and the elastic card seat 4.

[0037] In summary: By aligning the shaft pin 1 with the component to be connected, rotating the adjusting block 22 of the adjusting component 2 drives the adjusting screw 21 to rotate. The adjusting screw 21 is threadedly connected to the threaded hole 34 on the adjusting block 33 of the adjusting seat 3, driving the adjusting seat 3 to adjust the spacing through the sliding connection between the adjusting block 33 and the shaft pin body 11, thus adapting to components of different thicknesses to be connected. The limiting post 36 on the fixing plate 35 slides with the limiting groove 13 of the shaft pin body 11 to limit the movement trajectory. When fixing the shaft pin, the cotter pin 6 is inserted into the fixing shell 31 of the adjusting seat 3. The clamping blocks 47 on both sides move inward under the action of the spring 46. The cylindrical block 42 restricts the movement trajectory of the clamping blocks 47, and the baffle 44 restricts the retraction distance. The clamping blocks 47 are locked into the clamping groove 61 of the cotter pin 6 to complete the fixation. The first magnet 51 and the second magnet 52 of the adsorption component 5 are attracted to ensure that the elastic seat 4 remains stable under different postures of the shaft pin. When disassembling, the cotter pin 6 is pulled upward, and the clamping blocks 47 in the clamping groove 61 drive the elastic seat 4 to move, so that the rectangular guide block 43 separates along the inclined groove 311, realizing quick disassembly and assembly, and improving the adaptability, stability and efficiency of the shaft pin.

[0038] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
