Description

Technical Field

[0001] This utility model relates to the field of wrench tools, and in particular to an electric 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 use a pry bar inserted through the adjusting rod and grip both ends to rotate it, thus rotating the adjusting rod. 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. Manually rotating the adjusting rod requires high physical exertion, easily causing muscle fatigue, and the operation is time-consuming and inefficient. Utility Model Content

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] In the description of this utility model, the use of terms such as first, second, third, fourth, and fifth is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0027] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] 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.

[0029] Reference Figures 1 to 5 This utility model discloses an electric wrench for turnbuckles, comprising an electric drive module 100 and a clamping plate assembly 200 rotatably disposed on the electric drive module 100. The clamping plate assembly 200 has a clamping groove 221 and a first opening 222 communicating with the clamping groove 221. When the electric wrench is moved so that the adjusting rod 400 of the turnbuckle passes through the first opening 222 into the clamping groove 221, the electric drive module 100 can drive the clamping plate assembly 200 to rotate, causing the groove wall of the clamping groove 221 to push the adjusting rod 400 to rotate. The contour of the clamping groove 221 matches the circumferential contour of the adjusting rod 400.

[0030] It is understandable that the contour of the groove 221 matches the circumferential outer contour of the adjusting rod body 400, as referenced. Figure 3 The outline of the groove 221 is roughly similar to the circumferential outline of the adjusting rod 400. When the adjusting rod 400 passes through the groove 221, there is a reasonable gap between the groove wall of the groove 221 and the adjusting rod 400 (the width of the reasonable gap is about 3mm), so as to facilitate quick insertion and removal operations, reduce wear and stress concentration.

[0031] The process by which a user uses the electric wrench of this application to drive the adjusting rod 400 of the turnbuckle to rotate is as follows: 1. Move the electric wrench so that the adjusting rod 400 of the turnbuckle passes through the first opening 222 and is inserted into the clamping groove 221; 2. Start the electric drive module 100 so that the electric drive module 100 drives the clamping plate assembly 200 to rotate, so that the groove wall of the clamping groove 221 pushes the adjusting rod 400 to rotate. Therefore, on the one hand, the user only needs to hold the electric wrench and start the electric drive module 100 to drive the adjustment rod 400, which is inserted into the clamping groove 221, to rotate. In other words, the user does not need to swing it as much as when using a crowbar, so the adjustment rod 400 can be driven to rotate in a narrow space. On the other hand, the rotation of the adjustment rod 400 is achieved by the electric drive module 100, during which the user only needs to hold the electric wrench (the manual operation of holding the electric wrench is less strenuous than the traditional manual operation of using a crowbar to drive the adjustment rod 400 to rotate). In other words, the electric drive module 100 replaces the traditional manual operation of the user to drive the adjustment rod 400 to rotate, thus reducing the probability of muscle fatigue and greatly shortening the time required to complete the operation of driving the adjustment rod 400 to rotate, and greatly improving the efficiency of completing the operation of rotating the adjustment rod 400.

[0032] In this embodiment, refer to Figures 2 to 5 The clamping plate assembly 200 includes a transmission component 210 and a clamping plate component 220. The transmission component 210 is rotatably mounted on the electric drive module 100, and the clamping plate component 220 is mounted on the transmission component 210. The clamping plate component 220 has the aforementioned clamping groove 221 and the aforementioned first opening 222. The transmission component 210 has a communicating second opening 211 and a clearance through hole 212. When the electric wrench is moved so that the adjusting rod body 400 of the turnbuckle passes through the second opening 211 and the first opening 222 in sequence and enters the clamping groove 221 and the clearance through hole 212, the electric drive module 100 can drive the transmission component 210 to rotate, so that the groove wall of the clamping groove 221 pushes the adjusting rod body 400 to rotate.

[0033] The transmission component 210 is provided with a communicating second opening 211 and a clearance through hole 212. The electric drive module 100 can drive the transmission component 210 to rotate. Specifically, refer to Figures 2 to 5 The transmission component 210 has a C-shaped structure. The outer wall of the transmission component 210 is provided with teeth 213 that mesh with the electric drive module 100. The electric drive module 100 can drive the transmission component 210 to rotate through the teeth 213. The notch and inner hole of the transmission component 210 are respectively the second opening 211 and the clearance through hole 212. The clamping plate 220 is provided in the clearance through hole 212.

[0034] It is understandable that the moving electric wrench causes the adjusting rod 400 of the turnbuckle to pass through the second opening 211 and the first opening 222 sequentially into the clamping groove 221 and the clearance through hole 212. Since the clamping plate 220 is located within the clearance through hole 212, when the adjusting rod 400 passes through the second opening 211 and the first opening 222 sequentially into the clamping groove 221, it simultaneously passes into the clearance through hole 212. See [reference needed] for details. Figure 3 and Figure 4 As shown.

[0035] With the above structure, the clamping plate 220 is disposed in the clearance through hole 212, which can improve the structural compactness of the overall clamping plate assembly 200.

[0036] The clamping plate 220 is located within the clearance through hole 212. For details, please refer to [reference needed]. Figure 4 and Figure 5 The wall of the through hole 212 is provided with a mounting platform 212A, the mounting platform 212A is provided with a first hole 212A1, the clamping plate 220 is provided with a second hole 223, and the bolt and nut assembly 300 passes through the first hole 212A1 and the second hole 223.

[0037] With the above structure, the clamping plate 220 is detachably disposed in the clearance through hole 212. Therefore, when the clamping plate 220 is damaged, the user can replace the clamping plate 220 so that the entire clamping plate assembly 200 can be put back into use.

[0038] In some embodiments, the clamping plate 220 can be detachably mounted on the mounting platform 212A via a snap-fit ​​hole structure that meets structural strength requirements.

[0039] In some embodiments, the transmission member 210 and the clamping plate member 220 are integrally formed structures.

[0040] In order to distribute the contact stress and to improve the stability of the adjusting rod 400, which is driven to rotate through the clamp 221, refer to Figure 4 and Figure 5 Two clamping plates 220 are provided, which are arranged side by side and located on both sides of the mounting platform 212A. The bolt and nut assembly 300 passes through one first hole 212A 1 and two second holes 223, so that the two clamping plates 220 can be placed on the mounting platform 212A simultaneously with fewer connecting parts involved in the design.

[0041] In some embodiments, the clamping plate members 220 may be provided as four, and the four clamping plate members 220 are arranged side by side in the clearance through hole 212, wherein two clamping plate members 220 are provided on one side of the mounting platform 212A, and the other two clamping plate members 220 are provided on the other side of the mounting platform 212A.

[0042] In this embodiment, refer to Figures 1 to 5 The clamping plate 220 is provided with a material-saving through hole 224.

[0043] With the above structure, the material-saving through hole 224 can optimize the appearance of the clamping plate 220 on the one hand, and reduce the weight of the clamping plate 220 on the other hand, so as to reduce the weight of the front end of the overall electric wrench (lightweight design under the premise of structural strength).

[0044] 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.
