Description

Technical Field

[0001] This application relates to the field of handle repair, and more particularly to a handle repair tool. Background Technology

[0002] After the handle's stem is removed, as follows Figure 1 and Figure 2 As shown, it includes a gear 101, a square rod 102, a square tube 103, and a bolt 104. The gear 101 is fixed at the end of the square rod 102. The square rod 102 is inserted into the inner cavity of the square tube 103 and fixed by the bolt 104. The gear 101 is exposed on the outside of the positioning plate 105.

[0003] During the disassembly of the handle, the bolt 104 must be removed first before the various parts on the handle can be disassembled. When the bolt 104 is removed, it will cause the square tube 103 and the gear 101 to rotate synchronously. Therefore, it is necessary to restrict the rotation of either the gear 101 or the square tube 103 in order to achieve the purpose of disassembling the bolt 104.

[0004] like Figure 2 As shown, a toggle gear 106 is fixedly installed on the outer wall of the square tube 103. Two levers 107, located on both sides of the square tube 103, are swung on the handle. The levers 107 are equipped with toggle balls 108 that are inserted into the tooth grooves of the toggle gear 106. Currently, in order to remove the bolt 104, the levers 107 are pressed, causing the toggle balls 108 on the two levers 107 to be clamped in the toggle gear 106. By restricting the rotation of the toggle gear 106, the rotation of the square tube 103 is restricted, thereby enabling the removal of the bolt 104. During this disassembly process, the operator needs to press the levers 107 with one hand and keep the handle fixed, while holding the tool with the other hand to remove the bolt 104. This disassembly makes maintenance very inconvenient. Moreover, the exposed teeth of the gear 101 on the outside of the positioning plate 105 make the bottom of the handle uneven, making it impossible to place the handle upside down on the maintenance table for maintenance, which affects the maintenance efficiency of the handle.

[0005] Therefore, how to design a repair tool to improve the efficiency of handle repair has become a technical problem that urgently needs to be solved by people in this field. Utility Model Content

[0006] This application provides a handle repair tool to at least solve the above-mentioned technical problems existing in the prior art.

[0007] A handle repair tool is provided, including a base, a snap-fit ​​groove formed on the top wall of the base, the snap-fit ​​groove is used to place the positioning plate of the handle and restrict the rotation of the positioning plate, and the bottom wall of the snap-fit ​​groove is provided with a downwardly recessed positioning groove for placing a gear.

[0008] The positioning mechanism is installed on the side wall of the positioning groove and slides radially along the gear. The positioning mechanism engages with the gear tooth groove to limit the rotation of the gear.

[0009] In one embodiment, the depth of the snap-fit ​​groove is greater than or equal to the thickness of the positioning plate, and when the positioning plate is in the snap-fit ​​groove, the side wall of the positioning plate abuts against the inner wall of the snap-fit ​​groove.

[0010] In one embodiment, the positioning mechanism includes a positioning platform, a locking groove on one side wall of the positioning platform near the gear axis, the positioning platform and the side wall of the positioning groove being slidably connected along the radial direction of the gear, and a driving member that pushes the positioning platform toward the gear.

[0011] In one embodiment, the side wall of the positioning groove is provided with a sliding groove, and the side wall of the positioning platform is slidably connected to the inner wall of the sliding groove.

[0012] In one embodiment, the drive element includes a compression spring, one end of which abuts against the inner wall of the slide groove, and the other end of which abuts against the positioning table.

[0013] In one embodiment, a guide ramp is provided on the top wall of the positioning platform, with the side of the guide ramp closer to the gear being lower than the side of the guide ramp farther from the gear.

[0014] In one embodiment, the top wall of the locking groove is provided with a guide slope.

[0015] In one embodiment, the top wall of the base is rotatably connected to a flip frame, and when the handle is being maintained, the end side wall of the lever abuts against the inner wall of the flip frame to restrict the two levers from opening.

[0016] In one embodiment, the side wall of the flip frame near the lever is provided with a guide bevel.

[0017] Compared with the prior art, the handle repair tool of this application has the following advantages:

[0018] This application places the positioning plate of the handle in the snap-fit ​​groove to limit the rotation of the handle and improve the stability of the handle during maintenance. When the positioning plate is placed in the snap-fit ​​groove, the gear extends into the positioning groove and is snapped into the tooth groove of the gear by the positioning mechanism, thereby limiting the rotation of the gear. At this time, the hands can be freed and the bolts can be removed by maintenance tools, which facilitates the disassembly and assembly of the handle and improves the maintenance efficiency of the handle.

[0034] To make the objectives, features, and advantages of this application more apparent and understandable, 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Before introducing the solution of this application, the structure of the handle will be explained in order to provide a deeper understanding of the technical problem and the technical solution of this application.

[0036] like Figure 1 and Figure 2 As shown, after the handle is removed, it includes a gear 101, a square rod 102, a square tube 103, and a bolt 104. The gear 101 is fixedly mounted on one end of the square rod 102, which is inserted into the inner cavity of the square tube 103. The bolt 104 secures the square tube 103 to the square rod 102. The gear 101 is power-connected to the handle. It also includes an actuating gear 106, a lever 107, and an actuating ball 108. The actuating gear 106 is fixedly mounted on the outer wall of the square tube 103. Figure 8 As shown, one end of the lever 107 is rotatably connected to the handle via a rotating shaft 109. A moving ball 108 is mounted on the lever 107. The moving ball 108 is inserted into the tooth groove of the shift gear 106. When the square tube 103 drives the shift gear 106 to rotate, it can push the moving ball 108 to move, thereby enabling the lever 107 to rotate around the rotating shaft 109. At this time, the lever 107 can switch gears.

[0037] Specifically, such as Figure 8 As shown, a limiting post 110 is provided on the side of the handle away from the rotating shaft 109. The limiting post 110 is located inside the lever 107, which limits the lever 107 from continuing to rotate around the rotating shaft 109 toward the gear 106. It also includes a spring 111, wherein the two ends of the spring 111 are hooked to the ends of the two levers 107 respectively, and the spring 111 is located on the side away from the rotating shaft 109.

[0038] With the above configuration, when the actuating gear 106 actuates the lever 107 to rotate around the shaft 109 via the actuating ball 108, the spring 111 is opened. When the actuating ball 108 moves to another tooth groove of the actuating gear 106, the spring 111 drives the lever 107 to reset, so that the actuating ball 108 is locked back into the tooth groove of the actuating gear 106.

[0039] When repairing the handle, bolt 104 needs to be removed first before the rest of the handle parts can be disassembled in sequence. When the handle is held, bolt 104 can drive square tube 103 and gear 101 to rotate synchronously. At this time, bolt 104 cannot be disassembled.

[0040] Therefore, in order to complete the removal of bolt 104, the operator needs to restrict either square tube 103 or gear 101 to limit their synchronous rotation.

[0041] The existing method for removing bolt 104 is as follows: the operator holds the handle and then pinches the two levers 107 with his fingers to stretch the spring 111. At this time, the lever 107 restricts the square tube 103 from rotating by moving the ball bearing 108. Then, another hand tool can be used to remove bolt 104.

[0042] Meanwhile, since the handle is also equipped with a positioning plate 105, the gear 101 is located on one side of the positioning plate 105, and the bolt 104 is located on the other side of the positioning plate 105 opposite to the gear 101, when the handle is disassembled and assembled, the gear 101 protrudes outward, causing the bottom of the handle to be uneven. Therefore, it is impossible to place the handle upside down on the maintenance table for operation, and the hands cannot be freed, resulting in low disassembly efficiency of the handle and affecting the maintenance efficiency of the handle.

[0043] Therefore, this application designs a tooling that can improve the efficiency of handle maintenance.

[0044] like Figure 3 As shown, it includes a base 1, wherein the top wall of the base 1 is provided with a downwardly recessed snap-fit ​​groove 2, the snap-fit ​​groove 2 is used to place the positioning plate 105 on the handle, wherein the outer wall of the positioning plate 105 abuts against the inner wall of the snap-fit ​​groove 2, thereby restricting the handle from rotating on the base 1 during maintenance and improving the stability of the handle.

[0045] like Figure 3 and Figure 4 As shown, the bottom wall of the snap-fit ​​groove 2 is provided with a downwardly recessed positioning groove 3. When the handle is upside down, the positioning plate 105 snaps into the snap-fit ​​groove 2, and the gear 101 is placed in the positioning groove 3, thus completing the storage of the gear 101. This solves the problem that during the maintenance process, the handle cannot be placed on the maintenance platform for repair because the gear 101 protrudes outward.

[0046] After the gear 101 is placed inside the positioning groove 3, in order to facilitate the disassembly of the bolt 104, this application adopts a method of fixing the gear 101, thereby realizing the torsion of the bolt 104. Specifically, as follows: Figure 3 , Figure 4 and Figure 7As shown, a positioning mechanism 4 is provided in the positioning groove 3 and is slidably connected to the gear 101 in the radial direction. The positioning mechanism 4 is provided with a locking groove 411 on the side near the axis of the gear 101. The locking groove 411 is engaged with the tooth groove of the gear 101, thereby restricting the rotation of the gear 101 and thus enabling the disassembly of the bolt 104.

[0047] Specifically, such as Figure 4 and Figure 5 As shown, the positioning mechanism 4 includes a positioning platform 41, wherein the positioning platform 41 is slidably connected to the side wall of the positioning groove 3 along the radial direction of the gear 101, and the locking groove 411 is provided on the positioning platform 41.

[0048] In order to push the positioning platform 41 to move and make the locking groove 411 engage with the tooth groove of the gear 101, a driving component 5 is also included. Specifically, the driving component 5 is a compression spring. One end of the compression spring is fixedly connected to the positioning platform 41, and the other end of the compression spring is connected to the inner wall of the positioning groove 3. The compression spring is used to push the positioning platform 41.

[0049] To achieve the installation of positioning stage 41, such as Figure 4 and Figure 7 As shown, the side wall of the positioning groove 3 is provided with a sliding groove 31, wherein the side wall of the positioning platform 41 is slidably connected to the inner wall of the sliding groove 31, and the compression spring is installed in the sliding groove 31.

[0050] When the handle is placed upside down on the base 1, in order for the locking groove 411 of the positioning table 41 to automatically complete the locking operation of the gear 101, such as... Figure 5 As shown, a guide slope 412 is provided on the top wall of the positioning platform 41, wherein the side of the guide slope 412 closer to the axis of the gear 101 is lower than the side of the guide slope 412 farther away from the gear 101; the locking groove 411 is connected to the lower side of the guide slope 412.

[0051] With the above configuration, during the downward placement of the handle, the top wall of gear 101 abuts against the guide slope 412 of the positioning platform 41. As the handle continues to move downward, gear 101 applies a component force to the positioning platform 41 in the horizontal direction, pushing the positioning platform 41 to move into the slide groove 31 and compressing the compression spring. When gear 101 continues to move downward, the side wall of gear 101 abuts against the side wall of the positioning platform 41. At this time, the teeth of gear 101 are engaged in the locking groove 411 of the positioning platform 41, thereby restricting the rotation of gear 101 and realizing the positioning of gear 101. After gear 101 moves from the guide slope 412 to the side wall of the positioning platform 41, the compression spring pushes the positioning platform 41 to apply a reverse thrust to gear 101. It is worth noting that there are two positioning platforms 41, which are located on both sides of gear 101 respectively. The two sets of positioning platforms 41 are used to clamp gear 101 and fix gear 101.

[0052] To facilitate the smooth sliding of the teeth of gear 101 into the locking groove 411, such as Figure 5 As shown, the top sidewall of the locking groove 411 is provided with a guide slope 4111. When the gear 101 begins to contact the locking groove 411, the teeth of the gear 101 slide along the guide slope 4111 into the locking groove 411.

[0053] If the gear 101 of the handle requiring repair is damaged and cannot be positioned using the positioning mechanism 4, such as Figure 3 and Figure 8 As shown, the base 1 is also equipped with a flip-up frame 6. When the handle is placed upside down on the base 1, the flip-up frame 6 can be flipped from a horizontal state to a vertical state in order to disassemble the bolt 104. Figure 8 As shown, at this time, the end of the lever 107 away from the pivot 109 is inserted into the inside of the flip frame 6, and the side wall of the lever 107 abuts against the inner wall of the flip frame 6. The flip frame 6 restricts the lever 107 from rotating outward around the pivot 109, thereby stretching the spring 111. At this time, the flip frame 6 completes the limiting of the lever 107. The levers 107 on both sides lock the square tube 103 by turning the ball bearings 108, thereby enabling the bolt 104 to be removed.

[0054] To facilitate the insertion of the lever 107 into the inside of the flip frame 6, such as Figure 6 As shown, the inner side of the flip frame 6 is also provided with a guide bevel 61. Before the flip frame 6 is flipped into a vertical state, the guide bevel 61 first abuts against the end wall of the lever 107, so that the levers 107 move closer to each other, thereby making it easier to guide the end of the lever 107 to the inner side of the flip frame 6.

[0055] In actual use, the locking groove 411 of the positioning platform 41 is used to lock the gear 101, and the flip frame 6 is used to limit the lever 107. The two limit the gear 101 and the square tube 103 respectively, which facilitates the disassembly and assembly of the handle.
