Description

Technical Field

[0001] The present application belongs to the technical field of bolt disassembling and assembling tools, and in particular, to a bolt and nut disassembling and assembling tool based on a flexible belt. Background Art

[0002] With the promotion and use of photovoltaic equipment, new electric meters and other equipment, the disassembly and installation of bolts and nuts are also more frequent. The disassembly and installation of bolts and nuts is a very common technology, which is generally installed with a wrench or socket. However, it is not effective for nuts whose surfaces have been worn flat before installation. In addition, in some cases, the nuts are blocked by equipment during installation and cannot be disassembled and installed with a wrench or socket. The equipment at the corresponding position must be removed first, and then the nuts can be disassembled and installed.

[0003] There is a precedent of wrapping a belt around the nut for disassembly and assembly when disassembling bolts and nuts, which also proves the feasibility of covering the nut for disassembly and assembly. Based on the above experience, this application proposes a device for disassembling and assembling nuts using a flexible belt. Summary of the invention

[0004] In order to solve the above problems, the present application provides a bolt and nut disassembly tool based on a flexible belt.

[0005] The first purpose of the present application is to provide a bolt and nut disassembly tool based on a flexible belt. The present application relies on a flexible transmission belt to cover the nut, uses the deformation ability and friction force of the flexible transmission belt to "grab" the nut, and uses a handle to support and drive the transmission belt so that the nut can be disassembled.

[0006] In order to achieve the first purpose of this application, the technical solution of this application is:

[0007] The bolt and nut disassembling tool based on a flexible belt comprises a transmission belt and a handle matched with the transmission belt. The inner circumference of the transmission belt is provided with an anti-sliding block and synchronous belt teeth arranged around the transmission belt. The synchronous belt teeth are located above the anti-sliding block. A driving device is provided in the handle. A push switch for controlling the start of the driving device is provided on the handle. A synchronous pulley is provided on the output shaft of the driving device. The outer circumference of the synchronous pulley is matched with the synchronous belt teeth. The synchronous pulley is hingedly matched with the bearing in the bearing seat. A base is provided at the lower end of the bearing seat. The surface of the anti-sliding block is an anti-slip surface. The connection between the edge of the anti-sliding block and the transmission belt is a flexible block. When the anti-sliding block contacts the nut to be disassembled, the anti-sliding block is squeezed and Deformation occurs, and part of the anti-sliding block contacts the nut to be disassembled, and the synchronous belt teeth above the anti-sliding block contacting the nut to be disassembled contact the upper end surface of the nut to be disassembled. When the transmission belt of the present application cooperates with the nut, the transmission belt is provided with a deformable anti-sliding block. The contact between the anti-sliding block and the nut causes the anti-sliding block to deform and be connected to the nut with greater pressure and friction. The nut is gradually loosened and removed by relying on the rotation of the transmission belt, and the synchronous belt teeth are in contact with the nut. On the one hand, it also serves to increase the friction part. On the other hand, the synchronous belt teeth are pressed on the nut, so that the anti-sliding block can be in stable contact with the nut, reducing the displacement of the anti-sliding block in the height direction of the nut.

[0008] Furthermore, a support rod is provided on the bearing seat, an extension rod is provided on the support rod, a hinged seat is provided on the head end of the extension rod, a clamping wheel is hingedly provided on the hinged seat, the clamping wheel is squeezed on the nut to be disassembled, and matching through grooves are provided on the support rod and the extension rod, the matching through grooves on the support rod and the matching through grooves on the extension rod are arranged overlappingly, a group of locking screws are passed through the matching through grooves, a locking nut is provided on the locking screw, and the locking screw and the locking nut fix the support rod and the extension rod together.

[0009] Furthermore, a connecting rod is provided on the bearing seat, a block is provided on the connecting rod, a support column is provided at one end of the block away from the connecting rod, a spring is provided on the support column, and the block is provided with staggered through grooves and blind grooves, the through groove passes through the block, and the blind groove does not pass through the block at the end where the block is connected to the support column; a sleeve is provided on the outer periphery of the spring, an insertion rod is provided in the sleeve, the insertion rod is inserted in the blind groove, the spring is compressed and arranged in the sleeve, an articulated seat is provided on the sleeve, a clamping wheel is articulated on the articulated seat, and the clamping wheel is squeezed on the nut to be disassembled.

[0010] The above two are two different implementation schemes, and their principle is to use a clamping wheel to press the nut, increase the pressure of the transmission belt on the nut, and reduce the displacement of the anti-sliding block in the height direction of the nut, thereby playing a stabilizing role.

[0011] Furthermore, the central axis of the clamping wheel is arranged parallel to the central line of the nut to be disassembled, and the clamping wheel is pressed at the central position of the outer periphery of the nut to be disassembled.

[0012] Furthermore, an installation mark is provided on the sleeve, and the installation mark is used to indicate that the insertion rod is inserted out of the through slot and then inserted into the blind slot, so that the sleeve is fixed on the stopper.

[0013] Furthermore, a screw hole is provided in the output shaft of the driving device, and a mounting hole that passes through the synchronous pulley is provided on the synchronous pulley. The screw rod is passed through the mounting hole and is threadedly connected to the screw hole. A connecting plate is provided at the lower end of the synchronous pulley, and an articulated shaft is provided on the connecting plate. The articulated shaft is inserted into the bearing in the bearing seat.

[0014] Furthermore, the lower end surface of the base is a non-slip surface, or the lower end surface of the base is provided with a cone, and the base is used to support the handle.

[0015] Furthermore, the handle is provided with depressions for cooperating with the fingers on the palm and a depression for cooperating with the base of the palm, so that the thumb of the palm is pressed on the upper end of the handle and the thumb presses the push switch on the handle. This handle design can be matched with the palm and fingers, making it convenient for the hand to grasp the handle and rely on the thumb to press the push switch.

[0016] The second purpose of the present application is to provide a method for disassembling bolts and nuts. In the present application, a flexible transmission belt is wound around the nut, and a push switch on the handle is pressed so that a driving device on the handle drives the transmission belt, so that the nut can be disassembled.

[0017] To achieve the second purpose of this application, the technical solution of this application is:

[0018] A method for disassembling bolts and nuts, using the above-mentioned bolt and nut disassembling tool based on flexible belt, comprises the following steps:

[0019] S1. The anti-sliding block on the transmission belt is brought into contact with the outer periphery of the nut to be disassembled, so that the synchronous belt teeth are located above the nut to be disassembled and in contact with the nut to be disassembled;

[0020] S2, mesh the synchronous belt wheel with the synchronous belt teeth, and tighten the transmission belt through the handle;

[0021] S3. Support the base on the ground or wall;

[0022] S4. Adjust the position of the clamping wheel so that the clamping wheel and the transmission belt press both sides of the nut to be disassembled;

[0023] S5. Press the push switch on the handle to start the driving device, which drives the synchronous pulley to rotate and then drives the transmission belt to rotate. The rotation of the transmission belt drives the nut to be disassembled to rotate, so that the nut to be disassembled is loosened or the nut to be disassembled rotates.

[0024] Further, in step S4, the clamping wheel is moved to the surface of the nut to be disassembled, and then the locking nut is tightened, or the sleeve is pushed so that the sleeve compresses the spring, so that the clamping wheel is aligned with the surface of the nut to be disassembled and the sleeve is loosened so that the clamping wheel is pressed on one side of the nut to be disassembled.

[0025] Compared with the prior art, the beneficial effects of this application are:

[0026] 1. The transmission belt of the present application is a flexible belt structure made of rubber material. The transmission belt is provided with an anti-sliding block and synchronous belt teeth. The synchronous belt teeth are driven by a synchronous pulley on a handle. When the transmission belt cooperates with a nut, the contact between the anti-sliding block and the nut causes the anti-sliding block to deform and be connected to the nut with greater pressure and friction. Regardless of whether the edges and corners on the surface of the nut are smoothed, the nut is gradually loosened and removed by relying on the friction force of the transmission belt and rotation. The synchronous belt teeth on the transmission belt can contact the nut, which not only increases the friction part, but also allows the synchronous belt teeth to press on the nut, so that the anti-sliding block can stably contact the nut, reducing the displacement of the anti-sliding block in the height direction of the nut.

[0027] 2. The present application relies on a pressure wheel to press on the nut. When the nut rotates, the pressure wheel rotates with the nut and avoids the thread misalignment and locking of the nut due to the unilateral pressure of the transmission belt on the nut. The pressure wheel can increase the pressure between the transmission belt and the nut, so that the nut is "gripped" tighter and the nut can be more easily removed.

[0028] 3. The present application relies on the cooperation between the synchronous pulley on the output shaft of the driving device on the handle and the synchronous belt teeth on the transmission belt. The handle has a depression to make it easier for the handle to contact with the palm and rely on the palm to pull the handle so that the anti-slider on the transmission belt contacts the nut. The push switch installed on the handle is also convenient for the palm to press. The base under the handle is used to support the handle, and the base is supported on the ground or wall so that when the driving device on the handle drives the transmission belt to move, the handle will not be displaced.

[0043] Example 1

[0044] The present embodiment is an electric device for disassembling and assembling bolts and nuts similar to an electric wrench. It is used for disassembling and assembling bolts and nuts whose positions are not suitable for disassembling and assembling tools such as wrenches and sockets. It is used for disassembling and assembling bolts and nuts that are difficult to disassemble and assemble, such as when the big heads of nuts and bolts are severely worn. In this case, it is generally difficult for wrenches and sockets to function. Moreover, this situation is relatively common.

[0045] Therefore, the present embodiment discloses a bolt and nut disassembling tool based on a flexible belt. From the main body, it mainly includes a transmission belt 1 and a handle 4 matched with the transmission belt 1, wherein the structure of the transmission belt 1 is as follows: the transmission belt 1 is a belt, the main material of which is rubber, the inner periphery of the transmission belt 1 has an anti-slip block 2 and synchronous belt teeth 3 arranged around the transmission belt 1, the anti-slip block 2 is also made of rubber and can be deformed, the surface of the anti-slip block 2 is an anti-slip surface, the connection between the edge of the anti-slip block 2 and the transmission belt 1 is a flexible block, the flexible block is also made of rubber, the anti-slip block 2 and the flexible block can also be regarded as a whole, here just to distinguish the various structural positions, the synchronous belt teeth 3 are located above the anti-slip block 2, as the specific structure of the handle 4, the function of the handle 4 is to cooperate with the hand and drive the drive device, A driving device is installed in the handle 4. For example, the driving device of this embodiment is a driving motor. A push switch 5 for controlling the start of the driving device is installed on the handle 4, and the push switch 5 is arranged on the upper end surface of the handle 4, so that the push switch 5 can be conveniently matched with the thumb among the fingers. The handle 4 has a depression for matching with the fingers on the palm and a depression for matching with the tiger's mouth on the palm. The tiger's mouth refers to the palm area between the thumb and the index finger. The depression is used to support the fingers and the tiger's mouth. When in use, the thumb of the palm is pressed on the upper end of the handle 4, and the thumb presses the push switch 5 on the handle 4. This design of the handle 4 can be matched with the palm and fingers, which is convenient for the hand to grasp the handle 4, and the hand pulls the handle 4 so that the transmission belt 1 is pressed on the nut, and the thumb is used to press the push switch 5.

[0046] When the anti-slip block 2 of the present embodiment contacts the nut to be disassembled, the anti-slip block 2 is squeezed and deformed by the transmission belt 1 and the nut to be disassembled, and part of the anti-slip block 2 contacts the nut to be disassembled, and the synchronous belt teeth 3 above the anti-slip block 2 that contacts the nut to be disassembled contacts the upper end surface of the nut to be disassembled. When the transmission belt 1 of the present embodiment cooperates with the nut, the transmission belt 1 has a deformable anti-slip block 2, and the contact between the anti-slip block 2 and the nut causes the anti-slip block 2 to deform and be connected to the nut with greater pressure and friction. The nut is gradually loosened and removed by relying on the rotation of the transmission belt 1, and the synchronous belt teeth 3 contact the nut, thereby increasing the friction part, and the synchronous belt teeth 3 press on the nut, so that the anti-slip block 2 can be in stable contact with the nut, reducing the displacement of the anti-slip block 2 in the height direction of the nut.

[0047] A synchronous pulley 7 is installed on the output shaft 6 of the driving device. The outer periphery of the synchronous pulley 7 cooperates with the synchronous belt teeth 3. The synchronous pulley 7 is hingedly matched with the bearing in the bearing seat 12. Specifically, a screw hole 9 is opened in the output shaft 6 of the driving device, and the synchronous pulley 7 has a mounting hole 10 that penetrates the synchronous pulley 7. The screw rod is penetrated in the mounting hole 10 and is threadedly connected with the screw hole 9, so that the synchronous pulley 7 and the output shaft 6 of the driving device are fixed together. In addition, the output shaft 6 of the driving device has many protruding structures similar to keys, and there are also corresponding slots on the synchronous pulley 7, and the protruding structures on the output shaft 6 are inserted into the slots.

[0048] As the specific structure of the articulated shaft 8, the articulated shaft 8 and the synchronous pulley 7 of this embodiment are separate and are installed together by bolts. Specifically, a connecting disk 11 is installed at the lower end of the synchronous pulley 7, and the fixed disk is a protruding structure protruding from the synchronous pulley 7. The connecting disk 11 on the articulated shaft 8 has a through hole, and the fixed disk has a threaded hole. The bolts are threadedly inserted in the threaded holes, so that the fixed disk and the connecting disk 11 are fixed together, and the big head end of the bolt is prevented from protruding from the connecting disk 11. The articulated shaft 8 is inserted in the bearing 20 in the bearing seat 12. The bearing 20 in this embodiment adopts a deep groove ball bearing.

[0049] The bearing seat 12 has a base 13 at the lower end, and the base 13 is a structure connected to the bearing seat 12. Therefore, the bearing seat 12 does not move. The base 13 plays a role in fixing the bearing seat 12, which can be understood as the role of the support structure of the firearm. As an implementation scheme, the base 13 of this embodiment is a metal disc, and the lower end surface of the base 13 is an anti-slip surface. The anti-slip pattern on the anti-slip surface is a pattern with a concave-convex structure, or the lower end surface of the base 13 has a cone 19, and the base 13 is used to support the handle 4. The structure of the cone 19 has a narrow adaptability range. Generally, the corresponding anti-slip function can be achieved by using a base 13 structure with an anti-slip surface.

[0050] As a more specific implementation scheme, this embodiment uses a clamping wheel 16 and a transmission belt 1 to press the nut to be disassembled on both sides. Specifically, a support rod 14 is provided on the bearing seat 12. The bearing seat 12 and the support rod 14 are both metal rods. An extension rod 15 is installed on the support rod 14. The head end of the extension rod 15 is installed with a hinge seat, that is, the bearing seat 12 and the support rod 14 are integrated, the extension rod 15 and the hinge seat are integrated, and a clamping wheel 16 is hingedly installed on the hinge seat. The clamping wheel 16 is squeezed on the nut to be disassembled, and the support rod 14 and the extension rod 15 are provided with The matching through slot 17, the matching through slot 17 on the support rod 14 and the matching through slot 17 on the extension rod 15 are arranged in an overlapping manner, a group of locking screws are inserted into the matching through slot 17, and a locking nut 18 is arranged on the locking screw. The locking screw and the locking nut 18 fix the support rod 14 and the extension rod 15 together. In this embodiment, two groups of locking screws and locking nuts 18 are used to match. As another implementation scheme, which is also the best implementation scheme, the bearing seat 12 has a connecting rod 21, and the connecting rod 21 has a stopper 22, and the diameter of the stopper 22 is larger than The diameter of the connecting rod 21, the end of the stopper 22 away from the connecting rod 21 has a support column 23, and a spring 24 is arranged on the support column 23. The bearing seat 12, the connecting rod 21, the stopper 22, and the support column 23 in this embodiment are an integrated structure. The stopper 22 is provided with a staggered through groove 26 and a blind groove 27. The through groove 26 and the blind groove 27 of this embodiment are staggered at 90 degrees. The through groove 26 passes through the stopper 22, and the blind groove 27 does not pass through the stopper 22 at the end of the stopper 22 connected to the support column 23. A sleeve 25 is installed on the periphery of the spring 24, and the sleeve 25 has There is an insert rod 28, which is inserted into the blind groove 27. An installation mark 29 is set on the sleeve 25. The installation mark 29 is used to indicate that the insert rod 28 is inserted out of the through groove 26 and then inserted into the blind groove 27, so that the sleeve 25 is fixed on the block 22, so that the spring 24 is compressed in the sleeve 25. The sleeve 25 has a hinged seat, and a clamping wheel 16 is hingedly installed on the hinged seat. The clamping wheel 16 is squeezed on the nut to be disassembled, and the central axis of the clamping wheel 16 is arranged parallel to the center line of the nut to be disassembled, and the clamping wheel 16 is pressed at the central position of the periphery of the nut to be disassembled.

[0051] The principle of using the clamping wheel 16 in this embodiment is to use a clamping wheel 16 to press the nut, increase the pressure of the transmission belt 1 on the nut, and reduce the displacement of the anti-sliding block 2 in the height direction of the nut, thereby playing a stabilizing role. The clamping wheel 16 is pressed on the nut. When the nut rotates, the clamping wheel 16 rotates with the nut and avoids the thread misalignment and locking of the nut due to the unilateral pressure of the transmission belt 1 on the nut. The clamping wheel 16 can increase the pressure between the transmission belt 1 and the nut, so that the nut is "gripped" tighter and the nut can be more easily disassembled.

[0052] When such a tool is used, the present embodiment discloses a method for disassembling bolts and nuts, using the bolt and nut disassembling tool based on a flexible belt as claimed in the claim, comprising the following steps:

[0056] S4, adjust the position of the clamping wheel 16 so that the clamping wheel 16 and the transmission belt 1 press on both sides of the nut to be disassembled;

[0057] S5. Press the push switch 5 on the handle 4 to start the driving device, which drives the synchronous pulley 7 to rotate and then drives the transmission belt 1 to rotate. The rotation of the transmission belt 1 drives the nut to be disassembled to rotate, so that the nut to be disassembled is loosened or the nut to be disassembled rotates.

[0058] In step S4, the clamping wheel 16 is moved to the surface of the nut to be disassembled, and then the locking nut 18 is tightened, or the sleeve 25 is pushed so that the sleeve 25 compresses the spring 24, so that the clamping wheel 16 is aligned with the surface of the nut to be disassembled and the sleeve 25 is loosened, so that the clamping wheel 16 is pressed on one side of the nut to be disassembled.
