Abstract
Description
Technical Field
[0001] This utility model relates to the field of wrench technology, and in particular to a manual wrench for turnbuckles. Background Technology
[0002] A turnbuckle is a tool used to tighten, fix, or adjust linear objects such as wire ropes and cables. Its main body consists of connectors (hooks or eyelets) at both ends and an adjusting rod in the middle. Users can adjust the overall length by rotating the adjusting rod, thus tightening or loosening the linear object. However, in actual use, the inventors found that after connecting the connectors at both ends, users would insert a pry bar through the adjusting rod and rotate it by gripping both ends. However, this method of using a pry bar to rotate the adjusting rod has the following problems: 1. The pry bar requires a large amount of space to rotate, making it difficult to operate in confined spaces; 2. During the rotation, users may need to remove the pry bar, adjust, and then reinsert the adjusting rod, which is difficult and significantly reduces the efficiency of rotating the adjusting rod. Utility Model Content
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a manual wrench for turnbuckles.
[0004] A manual wrench for turnbuckles according to an embodiment of the present invention includes a wrench body and a push assembly. The wrench body has a communicating central hole and an opening. The wrench body is movable by a user so that the adjusting rod of the turnbuckle passes through the opening and into the central hole. The push assembly includes two push blocks, two rotation limiting blocks, and two elastic elements. The push blocks are rotatably mounted on the wrench body, and the rotation limiting blocks are fixed to the wrench body. The two elastic elements can respectively drive the two push blocks to rotate and reset, so that the two push blocks respectively abut against the two rotation limiting blocks. The wrench body can rotate clockwise, so that the two push blocks abutting against the corresponding rotation limiting blocks can respectively abut against the two sides of the adjusting rod passing through the central hole, so as to jointly push the adjusting rod to rotate clockwise. The wrench body can rotate counterclockwise, so that the adjusting rod passing through the central hole can push the two push blocks to rotate and release them from the corresponding rotation limiting blocks, and so that the two push blocks can rotate to avoid the adjusting rod from rotating relative to the wrench body.
[0005] A manual wrench for turnbuckles according to an embodiment of the present invention has at least the following beneficial effects:
[0006] The process by which a user uses a manual wrench to drive the adjusting rod of the turnbuckle to rotate is as follows: 1. Move the manual wrench so that the adjusting rod of the turnbuckle passes through the opening and into the center hole; 2. Drive the wrench body to repeatedly rotate forward and backward. When the wrench body rotates forward, the two push blocks that abut against the corresponding limit blocks abut against the two sides of the adjusting rod to push the adjusting rod body to rotate forward; when the wrench body rotates backward, the adjusting rod body pushes the two push blocks to rotate and release them from the corresponding limit blocks, and the two push blocks rotate to avoid the adjusting rod body rotating relative to the wrench body. Therefore, the push assembly forms a one-way engagement mechanism, which enables the one-way intermittent rotation of the adjusting rod body passing through the central hole. This allows the user to repeatedly swing the wrench body within a small angle range to drive the adjusting rod body to rotate in a narrow space. Moreover, in the process of driving the adjusting rod body of the turnbuckle to rotate, the manual wrench of this application does not need to be pulled out and reinstalled on the adjusting rod body. Therefore, this situation can be saved, and the efficiency of completing the rotation of the adjusting rod body can be greatly improved.
[0007] According to some embodiments of the present invention, the two push blocks are located on the same straight line at the rotational connection of the wrench body.
[0008] According to some embodiments of this utility model, the two push blocks at the rotatable connection of the wrench body and the center of the central hole are all located on the same straight line.
[0009] According to some embodiments of the present invention, at least two push-up components are provided, and the at least two push-up components are arranged circumferentially along the central hole. The wrench body can rotate clockwise, so that a corresponding push-up component can push the adjusting rod body passing through the central hole to rotate clockwise. The wrench body can rotate counterclockwise, so that a corresponding push-up component can avoid the adjusting rod body passing through the central hole from rotating relative to the wrench body, so that the adjusting rod body can rotate relative to the push-up block of the corresponding other push-up component, so that when the wrench body rotates clockwise, it is pushed clockwise by the other push-up component.
[0010] According to some embodiments of the present invention, the push block is provided with a push plane, and the push block can abut against the adjusting rod body through the push plane to push it to rotate forward.
[0011] According to some embodiments of this utility model, the two pushing planes are arranged in parallel.
[0012] According to some embodiments of the present invention, the wrench body includes a handle and a support plate disposed at one end of the handle. The support plate is provided with a central hole and an opening. The push block and the rotation limiting block are both disposed on the support plate. The elastic element connects the corresponding push block and the corresponding rotation limiting block.
[0013] According to some embodiments of the present invention, the support plates are configured as two and arranged opposite to each other, and the push block, the rotation limiting block and the elastic element are all disposed between the two support plates.
[0014] According to some embodiments of the present invention, the limiting block includes an abutting portion and two insertion portions disposed at both ends of the abutting portion. The two insertion portions are respectively inserted into the two support plates, and the two support plates abut against both ends of the abutting portion to form a rotation gap for the pushing block to rotate.
[0015] According to some embodiments of the present invention, the support plate is fitted with a kit, and the push block is rotatably fitted onto the corresponding kit. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0032] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integral molding; they can refer to a mechanical connection; they can refer to the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0033] Reference Figures 1 to 5 This utility model provides a manual wrench for turnbuckles, which includes a wrench body 100 and a push assembly 220.
[0034] The wrench body 100 has a central hole 121 and an opening 122. The wrench body 100 allows the user to move it so that the adjusting rod 400 of the turnbuckle passes through the opening 122 and into the central hole 121. The push assembly 200 includes two push blocks 210, two rotation limiting blocks 220, and two elastic elements 230. The push blocks 210 are rotatably mounted on the wrench body 100, and the rotation limiting blocks 220 are fixed to the wrench body 100. The two elastic elements 230 can respectively drive the two push blocks 210 to rotate and reset, so that the two push blocks 210 abut against the two rotation limiting blocks 220 respectively. The two push blocks 210 at the rotatable connection of the wrench body 100 and the center of the central hole 121 are all located on the same straight line.
[0035] It is understandable that the two push blocks 210 at the rotational connection point of the wrench body 100 and the center of the central hole 121 are all located on the same straight line, which can achieve a three-point alignment design, thereby optimizing the force transmission path and making rotation less strenuous.
[0036] It is understandable that the rotation limit block 220 is located on the rotation path of the push block 210. When the elastic element 230 drives the corresponding push block 210 to rotate to abut against the corresponding rotation limit block 220, the corresponding push block 210 is blocked by the corresponding rotation limit block 220 and stays in the initial position.
[0037] The process by which a user uses a manual wrench to drive the adjusting rod 400 of the turnbuckle to rotate is as follows: 1. Move the manual wrench so that the adjusting rod 400 of the turnbuckle passes through the opening 122 into the central hole 121; 2. Drive the wrench body to repeatedly rotate forward and backward. When the wrench body 100 rotates forward, the two push blocks 210 that abut against the corresponding rotation limit block 220 abut against the two sides of the adjusting rod 400 to push the adjusting rod 400 to rotate forward. When the wrench body 100 rotates backward, the adjusting rod 400 pushes the two push blocks 210 to rotate and release them from the corresponding rotation limit block 220, and causes the two push blocks 210 to rotate to avoid the adjusting rod 400 rotating relative to the wrench body 100. Therefore, the push assembly 200 forms a one-way engagement mechanism, which enables the one-way intermittent rotation of the adjusting rod 400 passing through the central hole 121. This allows the user to repeatedly swing the wrench body 100 within a small angle range to drive the adjusting rod 400 to rotate in a narrow space. Moreover, in the process of driving the adjusting rod 400 of the turnbuckle to rotate, the manual wrench of this application does not need to be pulled out and reinstalled on the adjusting rod 400. Therefore, this situation can be saved, and the efficiency of driving the adjusting rod 400 to rotate can be greatly improved.
[0038] It is understood that, in this embodiment, reference is made to... Figure 3 Rotating clockwise is clockwise rotation, and rotating counterclockwise is counterclockwise rotation.
[0039] In some embodiments, it may be sufficient to require that the two push blocks 210 are aligned in a straight line at the rotatable connection of the wrench body 100.
[0040] In this embodiment, refer to Figures 1 to 5 Two push-up components 200 are provided, which are arranged circumferentially along the central hole 121. The wrench body 100 can rotate forward, so that the corresponding push-up component 200 can push the adjusting rod 400 passing through the central hole 121 to rotate forward. The wrench body 100 can rotate in reverse, so that the corresponding push-up component 200 can avoid the adjusting rod 400 passing through the central hole 121 from rotating relative to the wrench body 100, so that the adjusting rod 400 can rotate relative to the wrench body 100 to abut against the push-up block 210 of the corresponding other push-up component 200, so that it can be pushed to rotate forward by the other push-up component 200 when the wrench body 100 rotates forward.
[0041] It is understandable that the corresponding push assembly 200 pushes the adjusting rod 400, which is inserted through the central hole 121, to rotate in the forward direction. That is, the two push blocks 210 of the corresponding push assembly 200 respectively abut against the two sides of the adjusting rod 400 to jointly push the adjusting rod 400 to rotate in the forward direction.
[0042] It is understandable that the corresponding push assembly 200 avoids the adjustment rod 400 passing through the central hole 121 from rotating relative to the wrench body 100, that is, the two push blocks 210 of the corresponding push assembly 200 rotate to avoid the adjustment rod 400 from rotating relative to the wrench body 100.
[0043] With the above structure, when the push assembly 200 is set to two, the user can repeatedly swing the wrench body 100 within a smaller angle range to drive the adjustment lever 400 to rotate in a narrower space.
[0044] In some embodiments, the pusher component 200 may be configured with three equal parts.
[0045] In this embodiment, refer to Figure 2 and Figure 3 The push block 210 is provided with a push surface 211, which can abut against the adjusting rod body 400 to push it to rotate forward. The adjusting rod body 400 is provided with an abutment surface 410 corresponding to the push surface 211. The two push surfaces 211 on the same push assembly 200 are arranged in parallel, that is, when the two push blocks 210 on the same push assembly 200 are both in the initial position, the two push surfaces 211 on the two push blocks 210 are arranged in parallel.
[0046] With the above structure, when the push block 210 abuts against the adjusting rod body 400 through the push plane 211 to push it to rotate, the push plane 211 abuts against the abutting plane 410 (surface contact). Therefore, the push block 210 and the adjusting rod body 400 have a large contact area, which can better drive the adjusting rod body 400 to rotate, and can reduce contact stress, thereby reducing the probability of component failure or malfunction caused by stress concentration.
[0047] It is understandable that in some embodiments, if the adjusting rod 400 does not have a contact surface 410 corresponding to the pushing surface 211, and the adjusting rod 400 only contacts the pushing surface 211 through a curved surface (line contact), the contact stress present in the line contact is also relatively small. In summary, the provision of the pushing surface 211 has the effect of reducing contact stress.
[0048] In this embodiment, refer to Figures 1 to 4 The wrench body 100 includes a handle 110 and a support plate 120 disposed at one end of the handle 110. The support plate 120 is provided with the aforementioned central hole 121 and the aforementioned opening 122. A push block 210 and a rotation limiting block 220 are both disposed on the support plate 120. An elastic member 230 connects the corresponding push block 210 and the corresponding rotation limiting block 220. There are two support plates 120 disposed opposite to each other. The push block 210, the rotation limiting block 220 and the elastic member 230 are all disposed between the two support plates 120.
[0049] In some embodiments, the support plate 120 may be configured as one.
[0050] The rotation limit block 220 is located between the two support plates 120. For details, please refer to [reference needed]. Figure 4 The limiting block 220 includes an abutment portion 221 and two insertion portions 222 respectively disposed at both ends of the abutment portion 221. The two insertion portions 222 are respectively inserted into two support plates 120, and the two support plates 120 abut against both ends of the abutment portion 221 to form a rotation gap S for the push block 210 to rotate. The abutment portion 221 and the insertion portions 222 are integrally formed structures.
[0051] It is understandable that the width of the rotation gap S is greater than the thickness of the push block 210 to allow the push block 210 to rotate, as detailed in the following reference. Figure 4 As shown.
[0052] The jacking block 210 is located between the two support plates 120. For details, please refer to [reference needed]. Figure 4 The support plate 120 is fitted with the kit 300, and the push block 210 is rotatably fitted onto the corresponding kit 300.
[0053] The elastic element 230 connects to the corresponding push block 210 and the corresponding rotation limit block 220. For details, please refer to... Figures 3 to 5The elastic element 230 is configured as a torsion spring. The elastic element 230 is sleeved on the corresponding kit 300, and one end of it is connected to the push block 210 which is also provided in the same kit 300, and the other end is hooked to the corresponding limit block 220.
[0054] In this embodiment, refer to Figure 4 and Figure 5 The kit 300 has a hollow structure, through which the bolt and nut assembly 500 can be inserted, so that the bolt and nut assembly 500 can be connected to the two support plates 120, thereby improving the structural strength of the wrench front end formed by the two support plates 120.
[0055] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
