Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-4 A T-shaped wire clamp for easy installation includes a first L-shaped inverted clamp tube 1 and a second L-shaped inverted clamp tube 2, both being L-shaped with a straight bottom and a chamfered top that curves inward, forming a natural wire clamping space. The first L-shaped inverted clamp tube 1 has limiting grooves 6 at both ends, and the second L-shaped inverted clamp tube 2 has positioning grooves 10 at both ends. A sliding locking device 7 is fixedly installed between the limiting groove 6 and the positioning groove 10. The sliding locking device 7 is designed as a sliding latch, with one end engaging with the limiting groove 6 and the other end inserting into the positioning groove 10, achieving locking and unlocking through sliding. Positioning grooves 12 are provided on both sides of the upper end of the first L-shaped inverted clamp tube 1 and the second L-shaped inverted clamp tube 2. A concave plate 3 is slidably installed in the positioning groove 12. The concave plate 3 is U-shaped and has positioning strips on both sides, which interact with the first L-shaped inverted clamp tube 2. The positioning grooves 12 on tube 1 and the second L-shaped inverted clamp tube 2 are matched to achieve left and right sliding. The upper ends of both the first L-shaped inverted clamp tube 1 and the second L-shaped inverted clamp tube 2 are provided with fixed sliding grooves 5. The upper end of the concave plate 3 is rotatably installed with a wire clamping device 4. The wire clamping device 4 can tighten or release the wire by rotating. The bottom inner side of the second L-shaped inverted clamp tube 2 is provided with a wire clamping groove 11. A wire clamping slider 8 is slidably installed in the wire clamping groove 11. The wire clamping slider 8 is designed to match the shape of the wire clamping groove 11. It may have an elastic element inside to provide appropriate clamping force when sliding. A limit bolt 9 is rotatably installed through the outside of the second L-shaped inverted clamp tube 2. The limit bolt 9 is a standard threaded bolt that passes through the outside of the second L-shaped inverted clamp tube 2. It is tightened by rotating to adjust and lock the position of the wire clamping slider 8.

[0019] When using, confirm the specifications of the wire or cable to be installed, select the appropriate T-type wire clamp model, connect the first L-shaped inverted clamp tube 1 and the second L-shaped inverted clamp tube 2 through the sliding locking device 7, slide one end of the sliding locking device 7 into the limiting groove 6 of the first L-shaped inverted clamp tube 1, insert the other end into the positioning groove 10 of the second L-shaped inverted clamp tube 2, and slide it to the locking position. Align the positioning strip of the concave plate 3 with the positioning groove 12 on the first L-shaped inverted clamp tube 1 and the second L-shaped inverted clamp tube 2, and slide it to the desired position. Install the wire clamping device 4 on the upper end of the concave plate 3, ensuring that the wire clamping device 4 can rotate freely. Place the wire to be fixed between the first L-shaped inverted clamp tube 1 and the second L-shaped inverted clamp tube 2, and tighten it by rotating the wire clamping device 4. Slide the wire clamping slider 8 to the second L-shaped inverted clamp tube 2. In the wire clamping groove 11 at the bottom of the T-type clamp tube 2, ensure that the slider matches the shape of the groove. According to the thickness of the wire, adjust the position of the wire clamping slider 8 by rotating the limiting bolt 9 to provide appropriate clamping force. Tighten the limiting bolt 9 to lock the position of the wire clamping slider 8 and ensure that the wire is stably clamped. The design of the sliding lock device 7 and the concave plate 3 simplifies the installation process and improves work efficiency. Users can complete the installation without complicated tools or skills. The T-type wire clamp can adapt to wires of different specifications. By adjusting the position of the clamping device 4 and the wire clamping slider 8, clamping and fixing of wires of different thicknesses can be achieved. The dual clamping design of the clamping device 4 and the wire clamping slider 8 ensures the stable connection of the wire under extreme conditions and improves the safety of the power system.

[0020] like Figure 2 or Figure 4As shown, the slide lock device 7 includes a limiting slider 701, a fixing plate 702, a positioning bolt 703, and a positioning slider 704. The limiting slider 701 is slidably installed inside the limiting groove 6. One end of the fixing plate 702 is rotatably connected to the periphery of the limiting slider 701. The positioning slider 704 is slidably installed inside the positioning groove 10. The positioning bolt 703 is rotatably installed at the other end of the fixing plate 702. The positioning bolt 703 is threadedly connected to the front end of the positioning slider 704. During the above-mentioned use, the positioning bolt 703 is rotatably installed at the other end of the fixing plate 702 to ensure that the bolt can rotate smoothly. The threaded part of the positioning bolt 703 is screwed into the front end of the positioning slider 704. By rotating the positioning bolt 703, it is gradually tightened until the fixing plate 702 and the positioning slider 704 are tightly fitted, thereby locking the slide lock device 7. When it is necessary to disassemble the T-shaped clamp, simply reverse the above installation steps. First, loosen the positioning bolt 703 to separate the fixing plate 702 from the positioning slider 704. Then, slide the limiting slider 701 and the positioning slider 704 out of the limiting groove 6 and the positioning groove 10, respectively. Finally, store the various components of the sliding lock device 7 separately for future use. Screw the threaded part of the positioning bolt 703 into the front end of the positioning slider 704. By rotating the positioning bolt 703, gradually tighten it until the fixing plate 702 and the positioning slider 704 are tightly fitted, thus locking the sliding lock device 7. Through the clever cooperation of the limiting slider 701, the fixing plate 702, the positioning bolt 703, and the positioning slider 704, a stable connection between the first L-shaped inverted clamp tube 1 and the second L-shaped inverted clamp tube 2 is ensured. Even under extreme conditions, the connection remains firm. The design of the sliding lock device 7 has a certain degree of flexibility, which can adapt to T-shaped wire clamps of different specifications and sizes. At the same time, by adjusting the tightening degree of the positioning bolt 703, it can adapt to different fastening requirements.

[0021] like Figure 3 or Figure 4As shown, the wire clamping device 4 includes a threaded connecting rod 401, an arc-shaped upper clamping plate 402, an arc-shaped lower clamping plate 403, a spring 404, and a baffle 405. The threaded connecting rod 401 is rotatably mounted on the upper end of the concave plate 3. The upper end of the arc-shaped upper clamping plate 402 is rotatably connected to the bottom of the threaded connecting rod 401. The baffle 405 is fixedly mounted on both sides of the inner wall of the concave plate 3. The arc-shaped upper clamping plate 402 is slidably mounted on the inner side of the baffle 405. The arc-shaped lower clamping plate 403 is slidably mounted in the fixed groove 5. One end of the spring 404 is fixedly mounted on the bottom of the arc-shaped lower clamping plate 403 and fixedly connected to the bottom of the fixed groove 5. In the above-mentioned use, the wire to be clamped is placed on the arc-shaped upper clamping plate 401. Between the upper and lower arc-shaped clamping plates 402 and 403, the threaded connecting rod 401 is rotated to move downwards, causing the upper arc-shaped clamping plate 402 to press the wire downwards. Simultaneously, the lower arc-shaped clamping plate 403 moves upwards under the action of the spring 404, clamping the wire together with the upper clamping plate. The rotation degree of the threaded connecting rod 401 can be adjusted as needed to control the clamping force on the wire. When it is necessary to release the wire, simply rotate the threaded connecting rod 401 in the opposite direction to move it upwards, separating the upper and lower arc-shaped clamping plates 402 and releasing the wire. By rotating the threaded connecting rod 401, the position of the upper arc-shaped clamping plate 402 can be easily adjusted, thus achieving precise control of the clamping force on the wire. This design allows the wire clamping device 4 to adapt to wires of different specifications and sizes. The various components of the wire clamping device 4 are rationally designed, and the installation process is simple and quick. Users can complete the installation and adjustment without complicated tools or skills.

[0022] like Figure 4 As shown, positioning strips are fixedly installed on both sides of the bottom of the inner wall of the concave plate 3. The positioning strips are slidably connected to the positioning groove 12. An anti-slip layer is fixedly installed between the positioning strips and the positioning groove 12. During the above-mentioned use, the sliding connection design between the positioning strips and the positioning groove 12 enables the concave plate 3 to slide stably and be accurately positioned on the clamping tube, which improves the convenience of installation and ensures that the concave plate 3 will not slide or fall off accidentally during use. The addition of the anti-slip layer further enhances the friction between the positioning strips and the positioning groove 12, thereby improving the connection stability between the concave plate 3 and the clamping tube.

[0023] like Figure 2 or Figure 3 As shown, limit strips are fixedly installed on both sides of the wire clamping slider 8. The limit strips are slidably connected to both sides of the inner wall of the wire clamping groove 11. Anti-slip textures are fixedly installed between the wire clamping slider 8 and the wire clamping groove 11. During the above-mentioned use, the sliding connection design between the limit strips and both sides of the inner wall of the wire clamping groove 11 allows the wire clamping slider 8 to slide stably and be accurately positioned in the groove, improving the convenience of installation and ensuring that the slider will not slide or fall off accidentally during use, thus ensuring the stable clamping of the wire. The addition of anti-slip textures further enhances the friction between the wire clamping slider 8 and the wire clamping groove 11, thereby improving the stability of the connection.

[0024] 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.
