Description

Technical Field

[0001] The utility model belongs to the technical field of quick-release tools, and in particular relates to a nut quick-release tool. Background Art

[0002] When removing a nut, a wrench is usually used to engage the nut from the side, and the nut is rotated and removed by turning the wrench handle. However, due to factors such as the maximum force application point of a person being limited within a certain angle and the limited space for installing the nut, it is impossible to keep the wrench handle rotating in one direction. Therefore, the wrench needs to be rotated a small angle to release the engagement state between the wrench and the nut, and then the angle of the handle needs to be adjusted to re-engage and apply force. Removing a nut requires repeated repeated actions, which is very time-consuming and labor-intensive, and has low disassembly efficiency. In addition, since the wrench's bayonet is the same size as the nut, the process of aligning the two requires the operator to concentrate and repeatedly align them, resulting in a very poor user experience. Utility Model Content

[0003] The utility model aims to solve the above problems and provide a nut quick-release tool to solve the technical problem that the existing wrench needs to be constantly re-engaged when removing the nut, which is time-consuming and labor-intensive.

[0004] The utility model is realized through the following technical solutions: a nut quick-release tool, comprising a shell, a one-way bearing and a handle, the handle being fixedly mounted on the outer surface of the shell, two openings communicating with each other being provided at both ends of the shell, the one-way bearing being arranged in the shell, a rotating shaft being provided in the one-way bearing, two ends of the rotating shaft respectively extending outward from the two openings and being fixedly connected to two sleeves, and a clamping groove for inserting a nut being provided at both ends of the sleeve.

[0005] Furthermore, the shell is cylindrical in shape.

[0006] Furthermore, the number of the handles is two, and the two handles are symmetrically arranged on both sides of the shell.

[0007] Furthermore, a snap-in hole is provided at one end of the handle away from the shell, the plugging direction of the snap-in hole is perpendicular to the extending direction of the handle, the handle and the sleeve are perpendicular to each other, and the two handles are located on the same straight line.

[0008] Furthermore, the specifications of the nuts corresponding to the clamping holes on the two handles are different.

[0009] Furthermore, the specifications of the nuts corresponding to the clamping grooves on the two sleeves are different.

[0010] Furthermore, limiting grooves are provided on the outer surfaces of both ends of the rotating shaft, and a first mounting hole with an internal thread is provided on the sleeve. The first mounting hole is adapted to the size of the limiting groove, and a screw is detachably installed in the first mounting hole.

[0011] Furthermore, mounting grooves are provided on the outer surfaces of both ends of the rotating shaft, a second mounting hole with an aperture slightly larger than the length of the mounting groove is provided on the sleeve, and a fixed plug is provided in the second mounting hole. The diameter of one end of the fixed plug is smaller than the diameter of the second mounting hole and equal to the length of the mounting groove, and the diameter of the other end is larger than the aperture of the second mounting hole.

[0012] When the present invention is in use, the operator aligns the engaging groove on the sleeve with the nut to engage and fix it, and then rotates the housing along the locking direction of the one-way bearing. At this time, the housing and the sleeve are relatively locked and fixed through the rotating shaft and the one-way bearing. At this time, the rotation of the housing can drive the sleeve to rotate synchronously, so that the sleeve drives the nut it engages to rotate synchronously to achieve a single small rotation. Then the operator rotates the housing in the opposite direction. Since this direction is the free movement direction of the one-way bearing, the rotating shaft remains stationary after the single rotation, and only the housing rotates alone until it rotates to a certain angle and then rotates along the locking direction of the one-way bearing again. Repeating the above actions can gradually remove the nut. During this process, the operator's hand is always held on the housing and remains in position. The housing can be driven to rotate by rotating the wrist left and right. Compared with the existing wrench, it is more convenient and labor-saving to use, and the disassembly efficiency is high.

[0020] The present invention will be further described below with reference to specific examples and accompanying drawings.

[0021] like Figure 1-Figure 5 As shown, the utility model describes a nut quick-release tool, including a shell 1, a one-way bearing 2 and a handle 3. The handle 3 is fixedly mounted on the outer surface of the shell 1. Two openings 11 that are interconnected are provided at both ends of the shell 1. The one-way bearing 2 is arranged in the shell 1. A rotating shaft 21 is provided in the one-way bearing 2. The two ends of the rotating shaft 21 extend outward from the two openings 11 and are fixedly connected to two sleeves 4. Both ends of the sleeve 4 are provided with a clamping groove 41 for inserting a nut.

[0022] The present invention realizes the function of quickly removing the nut by simply twisting left and right by arranging the one-way bearing 2 to limit the relative rotation direction of the sleeve 4 and the housing 1. When in use, the operator aligns the clamping groove 41 on the sleeve 4 with the nut to clamp and fix it, and then rotates the housing 1 along the locking direction of the one-way bearing 2. At this time, the housing 1 and the sleeve 4 are relatively locked and fixed by the rotating shaft 21 and the one-way bearing 2. At this time, the rotation of the housing 1 can drive the sleeve 4 to rotate synchronously, so that the sleeve 4 drives the nut it is clamped to rotate synchronously to achieve a single small rotation. Then, the operator rotates the housing 1 in the opposite direction. Since this direction is the free movement direction of the one-way bearing 2, the rotating shaft 21 remains in the state after the single rotation and does not move. Only the housing 1 rotates alone until it rotates a certain angle and rotates again in the locking direction of the one-way bearing 2. Repeating the above actions can gradually remove the nut. During this process, the operator's hand always holds the housing 1 and keeps it in a fixed position. The housing 1 can be driven to rotate by rotating the wrist left and right. Compared with the existing wrench, it is more convenient and labor-saving to use, and has high disassembly efficiency.

[0023] In order to facilitate the operator to hold the shell 1, the shell 1 in the embodiment of the utility model is cylindrical in shape. When in use, it can be clamped on both sides of the handle 3 through the gaps between the fingers, and the palm cooperates with the fingers to fix the outer wall of the shell 1, which is comfortable to hold and use. Moreover, since the sleeve 4 can be used at both ends of the shell 1, the cylindrical setting of the shell 1 has little effect on the difference in the grip after the use direction is adjusted, thereby avoiding affecting the comfort of use.

[0024] Furthermore, in this embodiment, two handles 3 are provided, and the two handles 3 are symmetrically arranged on both sides of the shell 1. In this way, when the nut is rotated to a relatively loose state, the nut can be removed by applying a slight force to drive the nut to rotate. Therefore, setting two symmetrical handles 3 can adapt to the operator gently pushing from different angles to drive the shell 1 to rotate, making the disassembly work more labor-saving.

[0025] In addition, in the embodiment of the utility model, a snap-in hole 31 is provided at the end of the handle 3 away from the shell 1, and the plugging direction of the snap-in hole 31 is perpendicular to the extension direction of the handle 3. The handle 3 and the sleeve 4 are perpendicular to each other, and the two handles 3 are located on the same straight line. By providing the snap-in hole 31 on the handle 3, the operator can adapt to using the tool as a traditional wrench. Since there are two handles 3 and the snap-in hole 31 is provided at the end of the handle 3, the two wrenches can be used as traditional wrenches. The shell 1 between the two handles 3 is located in the middle, so it does not affect the operator's application of force to one end of the handle 3.

[0026] The specifications of the nuts corresponding to the snap-in holes 31 on the two handles 3 are different. By setting the specifications of the snap-in holes 31 on the two handles 3 of the tool to be different, the use direction of the handles 3 can be directly adjusted according to the use requirements, thereby increasing the practicality of the tool and avoiding the need to search for and replace tools of different specifications to affect work efficiency.

[0027] In the embodiment of the utility model, the snap-fitting grooves 41 on the two sleeves 4 at both ends of the rotating shaft 21 correspond to nuts of different specifications. By arranging the sleeves 4 at both ends of the shell 1, nuts of different specifications can be adapted for use. The applicable specifications of the snap-fitting grooves 41 can be different from the applicable specifications of the snap-fitting holes 31, which greatly increases the practical scope and improves work efficiency.

[0028] In some embodiments, the sleeve 4 can be configured as a replaceable detachable structure connected to the rotating shaft 21, specifically, as shown in FIG. Figure 4 As shown, a limiting groove 211 is provided on the outer surface of both ends of the rotating shaft 21, and a first mounting hole 42 with an internal thread is provided on the sleeve 4. The first mounting hole 42 is adapted to the limiting groove 211 in size, and a screw 421 is detachably installed in the first mounting hole 42. Under normal use, one end of the screw 421 is limited and fixed in the first mounting hole 42, and the other end abuts against the limiting groove 211, so that the sleeve 4 and the rotating shaft 21 maintain a relatively static fixed state. When the sleeve 4 needs to be replaced, the screw 421 is removed from the first mounting hole 42, so that the sleeve 4 and the rotating shaft 21 can be relatively separated, and the sleeve 4 is pulled out from one end of the rotating shaft 21 for replacement and then re-fixed.

[0029] Of course, in other embodiments, the sleeve 4 can always maintain a fixed connection with the rotating shaft 21, and in order to ensure the stability of the connection, some interference fits can be set to achieve long-term fixation, specifically, Figure 5 As shown, mounting grooves 212 are provided on the outer surfaces of both ends of the rotating shaft 21, and a second mounting hole 43 with an aperture slightly larger than the length of the mounting groove 212 is provided on the sleeve 4. A fixed plug 431 is provided in the second mounting hole 43. The diameter of one end of the fixed plug 431 is smaller than the diameter of the second mounting hole 43 and equal to the length of the mounting groove 212, and the diameter of the other end is slightly larger than the aperture of the second mounting hole 43. During installation, the end with a smaller diameter of the fixed plug 431 is inserted into the second mounting hole 43. As the fixed plug 431 is continuously pushed in, it is necessary to gradually apply force so that the larger diameter part of the fixed plug 431 is squeezed into the second mounting hole 43 to form a snug fit, and the smaller diameter end of the fixed plug 431 is simultaneously inserted into the mounting groove 212 on the rotating shaft 21, so that the rotating shaft 21 and the sleeve 4 are firmly connected.

[0030] The above embodiments are only preferred implementation methods of the present invention and are only used to explain the present invention rather than to limit the present invention. Any changes, replacements, combinations, simplifications, modifications, etc. made by those skilled in the art without departing from the spirit and principles of the present invention shall be considered as equivalent replacement methods and shall be included in the scope of protection of the present invention.
