Description

Technical Field

[0001] The present application belongs to the technical field of tool equipment, and specifically relates to a sleeve and a disassembly and assembly component. Background Art

[0002] The structures of round nuts and ordinary nuts are quite different. The outer edge of the round nut is in a circular shape, and ordinary wrenches cannot be used to install and / or remove the round nut.

[0003] In order to facilitate the disassembly and assembly of the circular nut, a disassembly hole needs to be reserved on the outer edge of the circular nut so that a semicircular wrench can clamp the circular nut. The circular nut can be installed and / or disassembled by turning the semicircular wrench. Otherwise, the circular nut cannot be installed and / or disassembled.

[0004] When removing the round nut using the above method, it is necessary to rotate the machine component, rotate the disassembly hole of the round nut installed on the machine component to the appropriate position, and then use the clamping point on the half-round wrench to clamp the disassembly hole of the round nut. Then, the operator holds the half-round wrench with one hand to firmly clamp it on the round nut, and uses the other hand to forcefully pull or hit the half-round wrench with a hammer until the round nut loosens. This operation method generally has the following disadvantages:

[0005] 1) Before removing the round nut, the machine component needs to be rotated, which makes the entire operation process more complicated. In particular, when the machine component is large or the space where the machine component is located is small, it is more difficult to complete the rotation of the machine component;

[0006] 2) When installing and / or removing the round nut, the operator needs to hold the half-circle wrench with one hand and use the other hand to forcefully turn the half-circle wrench or hit the half-circle wrench with a hammer. The disassembly process is cumbersome, and when turning or hitting the half-circle wrench, the stuck point on the half-circle wrench is easily dislodged from the disassembly hole on the round nut, posing a major safety hazard. Summary of the Invention

[0007] In order to solve the above technical problems, the present application provides a sleeve that facilitates the installation and / or removal of circular nuts, so as to solve the technical problems in the prior art that the operation process of the semi-circular wrench when installing and / or removing circular nuts is complicated and there are great safety hazards.

[0008] The technical solutions adopted to achieve the purpose of this application are:

[0009] A sleeve comprises a sleeve body and a pressing assembly;

[0010] A disassembly cavity is provided on the sleeve body, an opening communicating with the disassembly cavity is provided at the end of the sleeve body, and the clamping assembly is arranged in the disassembly cavity; when the sleeve body is sleeved on the circular nut through the disassembly cavity, the clamping surface of the clamping assembly and the side wall of the disassembly cavity jointly clamp the outer wall of the circular nut.

[0011] In order to better realize the present application, further optimization is made in the above structure, wherein the pressing assembly includes a pressing block and an elastic member;

[0012] Two ends of the elastic member are respectively connected to the pressing block and the side wall of the disassembly cavity, and the elastic member pushes the pressing block toward the middle of the disassembly cavity.

[0013] In order to better realize the present application, the above structure is further optimized, and a rotation-blocking head is provided in the disassembly cavity for limiting the rotation of the pressing block around the axis of the sleeve body.

[0014] In order to better implement the present application, further optimization is made in the above structure. There are two groups of anti-rotation heads, and the two groups of anti-rotation heads are respectively located on both sides of the pressing block.

[0015] In order to better realize the present application, further optimization is made in the above structure, and a guide slope A is provided on the side of the pressure block facing the anti-rotation head; when the sleeve body screws the circular nut, the pressure block squeezes the circular nut under the cooperation of the guide slope A and the anti-rotation head.

[0016] In order to better realize the present application, the above structure is further optimized, and a guide slope B is provided on the side of the pressure block facing the opening of the disassembly cavity to facilitate the circular nut to be inserted between the side wall of the disassembly cavity and the pressing surface of the pressure block.

[0017] In order to better realize the present application, further optimization is made in the above structure, and the pressing surface of the pressing block is provided with an anti-slip portion.

[0018] In order to better realize the present application, the above structure is further optimized. A mounting groove is provided on the side wall of the disassembly cavity, and one end of the elastic member away from the pressing block is provided in the mounting groove.

[0029] In order to enable those skilled in the art to which this application belongs to understand this application more clearly, the technical solution of this application is described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0030] In the embodiments of this application, Figure 1 As shown, the sleeve includes a sleeve body 1 and a pressing assembly 2; wherein,

[0031] The sleeve body 1 is provided with a disassembly cavity 11, and an end portion of the sleeve body 1 is provided with an opening communicating with the disassembly cavity 11, and the pressing assembly 2 is arranged in the disassembly cavity 11;

[0032] Specifically: the sleeve body 1 is a cylindrical structure, and the disassembly cavity 11 is an accommodating cavity opened at one end of the sleeve body 1. The sleeve body 1 can be directly sleeved on the circular nut through the disassembly cavity 11. When disassembling the circular nut, there is no need to adjust the position of the circular nut by rotating the machine parts, so that the sleeve is more convenient to install.

[0033] After the installation of the sleeve is completed, the pressing surface of the pressing assembly 2 in the sleeve body 1 can cooperate with the side wall of the disassembly cavity 11 to hold the outer side wall of the circular nut tightly. Figure 4 As shown, the operator can easily screw the circular nut by using the wrench and the sleeve body 1 to complete the installation and / or removal of the circular nut;

[0034] Moreover, during the process of screwing the circular nut, the sleeve body 1 is not easy to fall off from the circular nut. Even when struck with a hammer, the sleeve body 1 is not easy to fall off from the circular nut compared to the existing semicircular wrench, thereby effectively reducing the safety hazards during the installation and / or removal of the circular nut.

[0035] In some embodiments, the above-mentioned pressing assembly 2 includes a pressing block 21 and an elastic member 22, such as Figure 2 and Figure 3 shown; among them,

[0036] The pressing block 21 is arranged in the disassembly cavity 11 through an elastic member 22. The end of the elastic member 22 away from the pressing block 21 is connected to the side wall of the disassembly cavity 11, and the restoring force generated by the elastic member 22 can push the pressing block 21 toward the middle of the disassembly cavity 11.

[0037] When the sleeve body 1 is clamped on the circular nut, the restoring force of the elastic member 22 can squeeze the pressure block 21 tightly against the outer wall of the circular nut, so that the pressing surface of the pressure block 21 and the side wall of the disassembly cavity 11 can hold the circular nut tightly, so that the operator can screw the circular nut through the sleeve to achieve the installation and / or removal of the circular nut. Preferably, an anti-slip portion is provided on the pressing surface of the pressure block 21, and the roughness of the pressing surface of the pressure block 21 is increased by the anti-slip portion. When the pressing surface of the pressure block 21 and the side wall of the disassembly cavity 11 hold the circular nut tightly, the anti-slip portion can effectively increase the friction between the pressure block 21 and the circular nut, so as to avoid relative rotation between the sleeve body 1 and the circular nut when the sleeve is rotated.

[0038] It should be noted that the anti-slip portion can be an anti-slip pattern provided on the pressing surface of the pressing block 21 or an anti-slip pad made of rubber material, that is, any anti-slip structure in the prior art that can increase surface friction.

[0039] In some embodiments, the disassembly cavity 11 is provided with a rotation-stopping head 23 for limiting the rotation of the pressing block 21 around the axis of the sleeve body 1;

[0040] When the operator uses the sleeve body 1 to tighten the circular nut, since the pressure block 21 is set in the disassembly cavity 11 by the elastic member 22, that is, it is not rigidly connected, the static friction between the pressure block 21 and the circular nut will prevent the position of the pressure block 21 from changing. Relative to the sleeve body 1, the pressure block 21 moves in the opposite direction of the operator's rotation of the sleeve body 1. Figure 4 ;

[0041] After rotating a certain distance (the distance between the pressure block 21 and the anti-rotation head 23), the pressure block 21 will abut the anti-rotation head 23 to limit the pressure block 21 from continuing to rotate, so that the pressure block 21 and the side wall of the disassembly cavity 11 can hold the circular nut tightly, so that the operator can screw the circular nut through the sleeve to achieve the disassembly and / or installation of the circular nut.

[0042] Of course, there are two groups of anti-rotation heads 23, and the two groups of anti-rotation heads 23 are respectively located on both sides of the pressing block 21. Figure 3 and Figure 4 So that when the operator screws the circular nut clockwise or counterclockwise around the axis of the sleeve body 1, the pressing block 21 can be restricted by the anti-rotation head 23.

[0043] In some embodiments, the pressing block 21 is provided with a guide slope A211 on one side facing the anti-rotation head 23. Figures 3 to 5 As shown; when the operator uses the sleeve to screw the circular nut, the pressing block 21 squeezes the circular nut under the cooperation of the guide bevel A211 and the anti-rotation head 23, which greatly increases the static friction between the pressing block 21 and the circular nut. The greater the force of screwing the sleeve body 1, the greater the static friction between the pressing block 21 and the circular nut. Ultimately, the circular nut, the pressing block 21 and the sleeve body 1 cannot be displaced relative to each other and can only rotate at the same time to achieve the purpose of installing and / or removing the circular nut.

[0044] Specifically, there are two sets of the above-mentioned guide inclined surfaces A211, which are respectively arranged on both sides of the pressing block 21. One side of the guide inclined surface A211 is connected to the pressing surface of the pressing block 21, and the other side of the guide inclined surface A211 gradually extends toward the middle of the pressing block 21 and toward the elastic member 22, so that the cross-section of the pressing block 21 is an isosceles trapezoid.

[0045] When the sleeve is screwed to install and / or remove the circular nut, the side of the pressure block 21 will be stuck between the circular nut and the anti-rotation head 23. As the rotation distance increases, the pressure block 21 will move in the opposite direction of the operator's rotation of the sleeve body 1, and the position of the anti-rotation head 23 squeezed on the guide bevel A211 (the distance between the anti-rotation head 23 and the pressing surface of the pressure block 21 increases) will also change. Under the cooperation of the anti-rotation head 23 and the guide bevel A211, the static friction between the pressure block 21 and the circular nut increases, and ultimately the circular nut, the pressure block 21 and the sleeve body 1 cannot be relatively displaced, and can only rotate at the same time to achieve the purpose of installing and / or removing the circular nut. Preferably, the anti-rotation head 23 is provided with a chamfer on the side facing the guide bevel A211 to make the cooperation between the anti-rotation head 23 and the guide bevel A211 smoother.

[0046] In some embodiments, a guide slope B212 is provided on one side of the pressure block 21 facing the opening of the disassembly cavity 11 to facilitate the circular nut to be inserted between the side wall of the disassembly cavity 11 and the pressing surface of the pressure block 21. Figure 2 and Figure 5 As shown, one side of the guide slope B212 is connected to the side of the pressing block 21 close to the elastic member 22, and the other side of the guide slope B212 gradually extends obliquely toward the middle of the pressing block 21 and the direction of the pressing surface of the pressing block 21;

[0047] The setting of the guide bevel B212 can facilitate the cooperation between the sleeve body 1 and the circular nut, that is, when the diameter of the circular nut is larger than the distance between the clamping surface of the pressure block 21 and the side wall of the disassembly cavity 11 opposite to the clamping surface of the pressure block 21, the circular nut can squeeze the guide bevel B212 and push the pressure block 21 away from the center of the sleeve body 1 until the circular nut is completely stuck between the clamping surface of the pressure block 21 and the side wall of the disassembly cavity 11 opposite to the clamping surface of the pressure block 21, thereby making it more convenient to install the sleeve body 1.

[0048] In some embodiments, a mounting groove 12 is provided on the side wall of the disassembly cavity 11 , and an end of the elastic member 22 away from the pressing block 21 is provided in the mounting groove 12 ;

[0049] When the circular nut squeezes the pressure block 21 away from the center of the sleeve body 1, and the side of the pressure block 21 away from its pressing surface abuts against the side wall of the disassembly cavity 11, the elastic member 22 is completely immersed in the installation groove 12, and it will not be squeezed by the pressure block 21 and the sleeve body 1 and damaged, thereby ensuring the service life of the sleeve.

[0050] In some embodiments, a force rod connection hole 13 is provided on the sleeve body 1 to facilitate the installation of the force rod;

[0051] In the case of limited space or high tightening force, the force arm can be increased by adding a force rod to make the installation and / or removal of the round nut easier.

[0052] On the other hand, the present application also provides a disassembly assembly component, which includes a wrench and the above-mentioned sleeve; wherein,

[0053] The wrench is detachably connected to the sleeve; the sleeve is put on the round nut, and the round nut can be easily installed, tightened or removed by turning the sleeve with the wrench.

[0054] Through the above embodiments, the present application has the following beneficial effects or advantages:

[0055] 1) The sleeve body 1 in the sleeve provided in the present application can be sleeved on the circular nut at any angle. When removing the circular nut, there is no need to adjust the position of the circular nut by rotating the machine parts. The clamping surface of the clamping assembly 2 can cooperate with the side wall of the disassembly cavity 11 to jointly clamp the outer wall of the circular nut. The operator can easily screw the circular nut by using a wrench and the sleeve body 1 to complete the installation and / or removal of the circular nut.

[0056] 2) The sleeve body 1 can be sleeved on the circular nut, and its contact area with the circular nut is much larger than the contact area between the semicircular wrench in the prior art and the disassembly hole. During the disassembly of the circular nut, the sleeve is not easy to fall off the circular nut, thereby improving the safety of the sleeve when in use.

[0057] 3) The disassembly method of the sleeve does not need to cooperate with the disassembly hole on the circular nut, so there is no need to reserve a disassembly hole during the production of the circular nut, thereby improving the production efficiency of the circular nut.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.

[0059] Obviously, those skilled in the art may make various changes and modifications to this application without departing from the spirit and scope of this application.
