Description

Technical Field

[0001] The utility model belongs to the technical field related to weak electricity, and in particular relates to a weak electricity line positioning and clamping device. Background Art

[0002] Weak current generally refers to direct current circuits or audio, video lines, network lines, telephone lines, and AC voltages are generally within 36V. Household appliances such as telephones, computers, and television signal inputs (cable TV lines), audio equipment (output lines), etc. are all weak current electrical equipment. Weak current lines refer to the above signal lines with low transmission voltages, which are usually used for data transmission, communication, automatic control systems, etc.

[0003] For example, a Chinese utility model patent with announcement number CN220217013U discloses a weak-current line positioning and clamping device, which provides a blowing moving block. The user adjusts the position by moving the blowing moving block, and then rotates the fixing buckle to pull up or down the telescopic connecting rod to adjust the vertical position, and then rotates the fixing buckle to fix it. Because the serpentine connecting tube can bend freely and maintain the adjustment direction, the gas will be pushed out by the serpentine connecting tube. By adding a manual drying device that can maintain the position, the weak-current line positioning and clamping device can be more practical and can effectively improve work efficiency.

[0004] However, the device clamps and fixes the weak current line by means of an upper movable clamp and a lower movable clamp, clamping multiple lines together, so that when the user performs circuit maintenance, the upper movable clamp and the lower movable clamp need to be separated to release the clamping of multiple lines at the same time, making the reinstallation process after maintenance complicated.

[0005] In summary, there is currently a need for a weak current line positioning and clamping device that can specifically release the clamping state according to the circuit to be repaired. Utility Model Content

When a circuit fault occurs, the circuit at the corresponding circuit can be taken out by removing the external fixing block at the corresponding circuit, which is convenient for separate maintenance of the circuit and reduces the impact on other intact circuits during the maintenance process.

[0009] A further preferred technical solution is that the limit assembly includes a moving seat, a sliding groove is provided on the side of the moving seat, a bidirectional screw rod is installed in the sliding groove, and the surface of the bidirectional screw rod is threadedly connected to the limit plate.

[0010] A further preferred technical solution is that: limiting sliding grooves are arranged at equal intervals on the surface of the fixing ring, and the sliding blocks are slidably arranged in the limiting sliding grooves.

The left side of the top of the adjusting tube 17 is connected to a blowing hose 18 through a connecting pipe, which is convenient for drying the welding position in time when welding the weak current line. Two straight grooves are provided on the top of the clamping device plate 1, and two relative limit assemblies are slidably connected in the straight grooves, and a clamping assembly is installed on the top of the limit assembly.

[0031] The limit assembly includes a moving seat 2, sliding grooves are provided on both sides of the moving seat 2, a bidirectional screw rod 3 is installed in the sliding groove, and two relative limit plates 4 are threadedly connected to the surface of the bidirectional screw rod 3. The linear groove is a T-shaped groove, and the two relative limit plates 4 are respectively arranged inside and above the T-shaped groove, so that the two limit plates 4 can clamp the T-shaped groove to fix the moving seat 2. The outer sides of the tops of the two bidirectional screw rods 3 are connected by a synchronous belt drive.

[0032] The clamping assembly is used to clamp the weak current line. The clamping assembly includes two support plates 5 and a screw rod 6 fixedly connected to the top of the moving seat 2. One end of the screw rod 6 is fixedly connected to a hand wheel to facilitate the rotation of the screw rod 6. The tops of the two support plates 5 are fixedly connected to a fixing ring 7. The surface of the fixing ring 7 is evenly spaced with arc grooves, and balls are rotatably connected in the arc grooves to facilitate the movement of the weak current line. Sockets are evenly spaced on the right side of the fixing ring 7, and a plug rod 8 is installed at the socket. The outer side of the plug rod 8 is sleeved with an external fixing block 9. The surface of the external fixing block 9 is provided with a through groove that matches the plug rod 8, which is convenient for the plug rod 8 to fix the external fixing block 9. The surface of the screw rod 6 is sleeved with a bearing 10, and the bearing 10 is fixedly connected to the fixing ring 7 through four connecting rods.

According to the specific layout and design requirements, the distance between the clamping components can be flexibly adjusted to achieve the best line clamping effect and ensure the neatness and beauty of the line layout.

[0034] After the position adjustment of the clamping assembly is completed, the weak-current line is placed in the arc-shaped groove opened on the surface of the fixing ring 7. At the same time, the external fixing block 9 and the internal fixing block 13 wrap each weak-current line, and then the screw rod 6 is rotated to move the threaded tube 11. Under the action of the connecting piece 12, the internal fixing block 13 moves toward the external fixing block 9, thereby completing the clamping and fixing of the weak-current line, making it convenient to fix multiple weak-current lines at the same time, and improving the assembly efficiency of the device.

[0035] When it is necessary to inspect and repair a single weak current line, pull out the plug rod 8 at the corresponding position, then pull out the external fixing block 9 at that position, and finally take out the wire that needs to be inspected along the arc-shaped groove. After the inspection is completed, put the wire back to its original position, and then fix the external fixing block 9 at that position to its original position through the plug rod 8, so as to facilitate the separate inspection of the line, reduce the impact on other intact lines during the inspection process, and improve the safety of the device.

[0036] When welding the weak current line, start the hair dryer 16 and move the connecting movable block 15 so that the blowing hose 18 is facing the welding position. When performing welding and fixing work, the welding position can be dried in time, thereby improving the working efficiency of the device.
