Description

Technical Field

[0001] The utility model relates to the technical field of hexagonal wrenches, in particular to a multi-size hexagonal wrench. Background Art

[0002] A hexagonal wrench, also known as an Allen wrench or Allen wrench, is a hand tool used to tighten or loosen bolts or nuts with a hexagonal socket. Its design allows for effective operation in small or hard-to-reach spaces. A hexagonal wrench is mainly composed of a wrench stem, a handle, and a hexagonal head. The head of a hexagonal wrench is a hexagonal design whose size matches the hexagonal socket of the bolt or nut to be tightened or loosened. The handle part is usually cylindrical for easy grip and operation. Some hexagonal wrenches may have an L-shaped handle. This design allows for operation in hard-to-reach or space-constrained places. Hexagonal wrenches are usually made of high-hardness alloy steel.

[0003] In the current prior art, the hexagonal head and the wrench rod of the hexagonal wrench are connected by welding. As a result, when using the hexagonal wrench to loosen or tighten hexagon socket bolts or nuts of different sizes, it is necessary to replace the hexagonal wrench with a hexagonal head of the corresponding size, which makes it more troublesome to loosen or tighten different hexagonal bolts and makes it more troublesome for workers to carry hexagonal wrenches of multiple sizes. Therefore, a multi-size hexagonal wrench is proposed to solve the above problem. Utility Model Content

[0004] In response to the deficiencies in the prior art, the utility model provides a multi-size hexagonal wrench with the advantages of easy replacement of hexagonal heads of different sizes, etc., and solves the problem that the hexagonal head of the hexagonal wrench and the wrench rod are connected by welding, which results in the need to replace the hexagonal wrench with a hexagonal head of the corresponding size when using the hexagonal wrench to loosen or tighten hexagonal bolts or nuts of different sizes, thereby making it more troublesome to loosen and tighten hexagonal bolts of different sizes, and making it more troublesome for workers to carry hexagonal wrenches of multiple sizes.

[0005] To achieve the above object, the utility model provides the following technical solution: a multi-size hexagonal wrench, comprising a wrench rod, one end of which is provided with a hexagonal head, the other end of which is provided with a wrench handle, and a connecting structure and a control structure provided on the wrench rod;

[0006] The connecting structure includes a connecting square column fixedly connected to one side of the hexagonal head, one end of the connecting square column passes through and extends to the interior of the wrench rod, and the top and bottom of the wrench rod are provided with mounting grooves, and mounting plates are slidably installed inside the two mounting grooves, and locking components for clamping the connecting square column are provided on opposite sides of the two mounting plates, and abutment blocks are fixedly installed on the opposite sides of the two mounting plates, and positioning blocks for abutting the abutment blocks are slidably installed inside the two mounting grooves.

[0007] Furthermore, the control structure includes a control ring sleeve that is sleeved on the outer surface of the wrench rod, and the outer surface of the wrench rod is provided with a support component for supporting the rotation of the control ring sleeve. The internal thread of the control ring sleeve is connected to a threaded sleeve that is sleeved on the outer surface of the wrench rod, and the inner wall of the threaded sleeve is fixedly connected to two positioning blocks respectively.

[0008] Furthermore, the wrench handle is fixedly connected to one end of the wrench rod, and the wrench handle and the wrench rod are detachably mounted.

[0009] Furthermore, a square groove is provided at one end of the wrench rod, one end of the connecting square column passes through and extends into the interior of the square groove, and two arc grooves are provided at the top and bottom of the connecting square column.

[0010] Furthermore, the locking assembly includes four locking blocks, which are respectively fixedly mounted on opposite sides of the two mounting plates, and the four locking blocks respectively penetrate and extend into the arc-shaped groove.

[0011] Furthermore, the back sides of the two mounting plates are fixedly mounted with limiting blocks, the rear side walls of the inner cavities of the two mounting slots are provided with limiting slots, and the outer surfaces of the limiting blocks are slidably connected to the inner walls of the limiting slots.

[0012] Furthermore, the support assembly includes two bearings, both of which are fixedly mounted on the outer surface of the wrench rod, and the outer peripheral walls of the two bearings are respectively fixedly connected to the inner peripheral wall of the control ring sleeve.

[0013] Furthermore, a plurality of strip grooves are formed on the outer surface of the control ring sleeve, and the strip grooves are evenly distributed on the outer peripheral wall of the control ring sleeve.

[0014] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0015] The multi-size hexagonal wrench is provided with a connection structure and a control structure, which realizes the rotation of the control ring and controls the threaded sleeve to move to one side, thereby causing the moving threaded sleeve to drive the positioning block to move, thereby controlling the positioning block to move to the leftmost side of the installation slot, thereby releasing the positioning of the abutment block. However, the staff can pull the hexagonal head to one side so that the arc groove on the connecting square column squeezes the locking assembly into the installation slot, thereby quickly disassembling the hexagonal head, thereby facilitating the replacement of hexagonal heads of different sizes and facilitating the tightening of bolts of different sizes. In addition, the staff only needs to carry one hexagonal wrench and multiple hexagonal heads of different sizes, thereby enhancing the use efficiency of the multi-size hexagonal wrench.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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] See also Figures 1 to 4 A multi-size hexagonal wrench in this embodiment includes a wrench rod 1, one end of the wrench rod 1 is provided with a hexagonal head 2, the other end of the wrench rod 1 is provided with a wrench handle 3, a connecting structure and a control structure are provided on the wrench rod 1, the wrench handle 3 is fixedly connected to one end of the wrench rod 1, and the wrench handle 3 and the wrench rod 1 are detachable and installed.

[0023] Example 1: Please refer to Figures 1 to 4In this embodiment, the connection structure includes a connecting square column 41 fixedly connected to one side of the hexagonal head 2, one end of the connecting square column 41 passes through and extends to the inside of the wrench rod 1, one end of the wrench rod 1 is provided with a square groove, one end of the connecting square column 41 passes through and extends to the inside of the square groove, the top and bottom of the connecting square column 41 are provided with two arc grooves to facilitate the connection between the hexagonal head 2 and the wrench rod 1, the top and bottom of the wrench rod 1 are provided with mounting grooves 42, and mounting plates 43 are slidably installed inside the two mounting grooves 42. A locking assembly 44 for clamping the connecting square column 41 is provided on the opposite side of the mounting plate 43. The locking assembly 44 includes four locking blocks, which are fixedly mounted on the opposite sides of the two mounting plates 43 respectively. The four locking blocks respectively penetrate and extend into the arc groove, so that the locking blocks can be inserted into the arc groove to fix the position of the connecting square column 41. Abutment blocks 45 are fixedly mounted on the opposite sides of the two mounting plates 43, and positioning blocks 46 for abutting the abutment blocks 45 are slidably mounted inside the two mounting grooves 42.

[0024] Among them, the back of the two mounting plates 43 are fixedly installed with limit blocks, and the rear side walls of the inner cavities of the two mounting grooves 42 are provided with limit grooves. The outer surface of the limit block is slidably connected to the inner wall of the limit groove to limit the up and down movement of the mounting plate 43 and prevent it from slipping.

[0025] By adopting the above technical solution, the two positioning blocks 46 are controlled to move to the leftmost side of the two mounting grooves 42 respectively, thereby releasing the positioning of the two abutment blocks 45. However, the staff can pull the hexagonal head 2 to one side so that the arc groove on the connecting square column 41 squeezes the locking block in the locking assembly 44 into the mounting groove 42, thereby completing the quick disassembly of the hexagonal head 2.

[0026] Example 2: Please refer to Figures 1 to 4 In this embodiment, the control structure includes a control ring sleeve 47 that is sleeved on the outer surface of the wrench rod 1. The outer surface of the control ring sleeve 47 is provided with a plurality of strip grooves, which are evenly distributed on the outer peripheral wall of the control ring sleeve 47 to increase the friction of the outer surface of the control ring sleeve 47, thereby facilitating rotation. The outer surface of the wrench rod 1 is provided with a support assembly 48 for supporting the rotation of the control ring sleeve 47. The internal thread of the control ring sleeve 47 is connected to a threaded sleeve 49 that is sleeved on the outer surface of the wrench rod 1, so that rotating the control ring sleeve 47 can control the left and right movement of the threaded sleeve 49. The inner wall of the threaded sleeve 49 is fixedly connected to the two positioning blocks 46 respectively.

[0027] Among them, the support assembly 48 includes two bearings, both of which are fixedly mounted on the outer surface of the wrench rod 1, and the outer peripheral walls of the two bearings are fixedly connected to the inner peripheral walls of the control ring sleeve 47, so as to facilitate the use of the bearings to support the rotation of the control ring sleeve 47.

[0028] By adopting the above technical solution, the rotating control ring 47 is realized and the threaded sleeve 49 is controlled to move to one side, so that the moving threaded sleeve 49 drives the two positioning blocks 46 to move, thereby controlling the two positioning blocks 46 to move to the leftmost side of the two mounting slots 42 respectively.

[0029] The working principle of the above embodiment is:

[0030] When replacing the hexagonal head 2 of this multi-size hexagonal wrench, the control ring sleeve 47 is rotated and the threaded sleeve 49 is controlled to move to one side, so that the moving threaded sleeve 49 drives the two positioning blocks 46 to move, thereby controlling the two positioning blocks 46 to move to the leftmost side of the two mounting grooves 42 respectively, thereby releasing the positioning of the two abutment blocks 45. However, the staff can pull the hexagonal head 2 to one side so that the arc groove on the connecting square column 41 squeezes the locking block in the locking assembly 44 into the mounting groove 42, thereby completing the quick disassembly of the hexagonal head 2, and then replace the hexagonal head 2 of a different size and insert the connecting square column 41 into the wrench rod 1, and then rotate the control ring sleeve 47 in the opposite direction to control the locking block to be inserted into the arc groove on the connecting square column 41, thereby completing the installation of the new hexagonal head 2.
