Description

Technical Field

[0001] This utility model belongs to the technical field of tension clamps, specifically relating to a pre-twisted tension clamp. Background Technology

[0002] Pre-twisted tension clamps are a widely used type of tension clamp used for fixing overhead line conductors and overhead optical cables at the middle and end. They are characterized by high gripping force, light weight, uniform stress distribution, good corrosion resistance, simple installation, and strong versatility.

[0003] Most current tension clamps can only fix the terminal of one cable. When dealing with multiple cables, multiple tension clamps need to be installed, which poses a great construction difficulty. Moreover, installing multiple tension clamps together can easily lead to problems with adjusting the installation position. Utility Model Content

[0004] The purpose of this invention is to provide a pre-twisted tension clamp to solve the problem that in the prior art, a single tension clamp can only be used to fix the end of a single cable, which is a limitation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pre-twisted tension clamp includes a U-shaped frame, a mounting bracket, and a stop pin that cooperates with both. The end of the U-shaped frame away from the mounting bracket is locked by a fastening bolt and a fastening nut. The end of the mounting bracket away from the fastening bolt and the fastening nut is connected to a tension ring, and the tension ring is provided with a quick-release assembly for connecting another tension ring. Cables are sleeved on the outside of each tension ring.

[0007] Preferably, the quick-installation assembly includes two fixing blocks symmetrically installed on the top surface of the tensioning ring located at the lower end. The two fixing blocks have sliding grooves on their opposite sides, and the length of each sliding groove is half the length of the fixing block.

[0008] Preferably, the quick-installation assembly further includes two insert blocks, each with a vertically arranged protruding post fixedly inserted at its end. The tops of the two protruding posts are fixedly connected to the bottom of the upper tensioning ring, and the two insert blocks are respectively slidably engaged with two sliding grooves.

[0009] Preferably, both fixing blocks are installed on the side of the lower tension ring away from the hanger, which facilitates the insertion of the two inserts at the bottom of the upper tension ring.

[0010] Preferably, the inner diameters of the two tensioning rings are consistent, and the inner diameter of the hook bracket is larger than the inner diameter of the tensioning ring.

[0011] Preferably, the bottom end of the stop pin can be connected to a release pin, and the bottom end of the stop pin has a round hole for the release pin to pass through.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By adding a quick-installation component, this utility model can add an installation position for a tension ring above the tension ring, thereby giving the tension clamp the ability to fix two cable terminals at once, which to a certain extent saves the installation of multiple tension clamps and effectively reduces the installation difficulty.

[0014] 2. In this utility model, the upper tensioning ring is inserted into the two fixing blocks on the lower tensioning ring by means of the two inserts below it. The tighter the upper cable is pulled, the tighter the connection between the two tensioning rings is, thereby avoiding the connection between the two tensioning rings from breaking and ensuring the continuous normal function of the two tensioning rings.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figures 1-3As shown, this utility model provides a pre-twisted tension clamp, including a U-shaped frame 1, a hanging bracket 7, and a stop pin 5 that cooperates with both. The bottom end of the stop pin 5 can be connected to a detachment pin, and the bottom end of the stop pin 5 has a round hole for the detachment pin to pass through, preventing the stop pin 5 from detaching from the connection between the U-shaped frame 1 and the hanging bracket 7. The end of the U-shaped frame 1 away from the hanging bracket 7 is locked by a fastening bolt 2 and a fastening nut 3. The end of the hanging bracket 7 away from the fastening bolt 2 and the fastening nut 3 is connected to a tension ring 4, and the tension ring 4 is provided with a quick-release assembly 8 for connecting another tension ring 4. Cables 6 are sleeved on the outside of each tension ring 4. By adding the quick-release assembly 8, the tension clamp can fix the ends of two cables at once, which to a certain extent saves the installation of multiple tension clamps. The inner diameters of the two tension rings 4 are consistent, and the inner diameter of the hanging bracket 7 is larger than the inner diameter of the tension ring 4.

[0023] In a further embodiment, refer to Figures 2-4 The quick-assembly assembly 8 includes two fixing blocks 81 symmetrically installed on the top surface of the tension ring 4 located at the lower end. The two fixing blocks 81 have sliding grooves 811 on their opposite sides, and the length of the two sliding grooves 811 is half the length of the fixing block 81, which facilitates the sliding insertion of the two insert blocks 83 into the two sliding grooves 811 of the two fixing blocks 81, thereby realizing the concentric assembly of the two tension rings 4.

[0024] The quick-installation assembly 8 also includes two insert blocks 83. Each of the two insert blocks 83 has a vertically arranged protruding post 82 fixedly inserted at its end. The top of each of the two protruding posts 82 is fixedly connected to the bottom of the upper tensioning ring 4. The two insert blocks 83 are respectively slidably engaged with two sliding grooves 811.

[0025] In this embodiment, the upper tensioning ring 4 is inserted into the two fixing blocks 81 on the lower tensioning ring 4 by means of the two inserts 83 below it. The tighter the upper cable 6 is pulled, the tighter the connection between the two tensioning rings 4 is, thereby avoiding the breakage of the connection between the two tensioning rings 4.

[0026] In a further embodiment, refer to Figure 3 and Figure 4 As shown, both fixing blocks 81 are installed on the side of the lower tension ring 4 away from the hanger 7, which facilitates the insertion of the two insert blocks 83 at the bottom of the upper tension ring 4.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
