At present, the installation of optical fiber on the busbar is done by manually tying the optical fiber to the busbar with cable ties. Workers need to tie the optical fiber along the path of the busbar several times at intervals until the end of the optical fiber is tied to the contact of the busbar. During this process, workers need to stick the optical fiber to the surface of the busbar with one hand and use the cable tie with the other hand to tie the optical fiber to the busbar. Such operation is inconvenient and easily causes the optical fiber to bend, increases the use length of the optical fiber, and increases the material cost of installation. Summary of the invention

[0029] In the prior art, when a worker bundles optical fibers onto a busbar of an electrical cabinet, he or she needs to use one hand to fit the optical fibers onto the surface of the busbar, and use the other hand to operate the cable tie to bundle the optical fibers onto the busbar. This operation is inconvenient and can easily cause the optical fibers to bend, increase the usable length of the optical fibers, and increase the material cost of the installation.

[0030] In order to solve this technical problem, the present invention provides an auxiliary clamping device 1000 for installing a temperature measuring optical fiber, so as to solve the problems of inconvenient bundling operation of the optical fiber 6 and bending of the optical fiber 6 during bundling.

[0031] See also Figures 1 to 3 The auxiliary clamping device 1000 for installing a temperature measuring optical fiber comprises:

[0032] The housing 1 has a pressing opening 11 and a swing opening 12 on both sides thereof, and a support foot 13 is provided at the bottom of the housing 1;

[0033] Two clamping mechanisms 2 are symmetrically arranged. The clamping mechanism 2 includes a fixed shaft 21, a clamping swing arm 22, a clamping member 23, and a torsion spring 24. The fixed shaft 21 is fixed in the housing 1. The clamping swing arm 22 is rotatably connected to the fixed shaft 21. The fixed shaft 21 divides the clamping swing arm 22 into a clamping section and a pressing section. The clamping section extends out from the swing opening 12. The portion of the clamping section extending out of the swing opening 12 is bent downward. The pressing section is located at the pressing opening 11. The torsion spring 24 is sleeved on the fixed shaft 21, and its two ends are fixed to the clamping swing arm 22 and the inner wall of the housing 1. The clamping member 23 is installed at the end of the clamping section. When the two pressing sections are pressed inward, the two clamping sections expand outward.

[0034] The positioning bar 3 is located below the housing 1 , and a groove is provided at the bottom of the positioning bar 3 . The positioning bar 3 is used to fix the optical fiber 6 when the clamping mechanism 2 clamps the busbar 5 .

[0035] The auxiliary clamping device 1000 for installing the temperature measuring optical fiber includes a shell 1, two clamping mechanisms 2, and a positioning strip 3. The clamping mechanism 2 includes a fixed shaft 21, a clamping swing arm 22, a clamping piece 23, and a torsion spring 24. The clamping swing arm 22 is divided into a clamping section and a pressing section. By pressing the pressing section inward, the clamping section is expanded outward, and the torsion spring 24 is in a torsion state. The clamping device is placed on the busbar 5, and the optical fiber 6 is placed between the busbar 5 and the clamping device. At this time, the pressing section is released, and the clamping section swings inward due to the reset force of the torsion spring 24, so that it is clamped on both sides of the busbar 5 by the clamping piece 23 located in the clamping section to achieve fixation. At this time, the optical fiber 6 is pressed downward by the groove of the positioning strip 3 to fix the optical fiber 6, so that the workers can use cable ties or the like to bundle the optical fiber 6 on the busbar 5, which is convenient for the workers to operate, and also ensures that the optical fiber 6 is in a straightened state, and ensures that the length of the installed optical fiber 6 will not be too long due to the bending of the optical fiber 6, thereby reducing the material cost of the installation.

[0036] In one embodiment of the present invention, a pressing member 4 is slidably provided at both pressing ports 11, and the two pressing members 4 can slide and press in a direction close to each other, and a roller 221 is provided at one end of the pressing section away from the clamping section, and the roller 221 abuts against the inner wall surface of the pressing member 4. Firstly, the pressing member 4 is slidably pressed, and the structure is relatively stable, and it is also convenient for users to operate. Secondly, the roller 221 is provided at one end of the pressing section, and when the pressing member 4 is pressed, the roller 221 can slide on the inner wall surface of the pressing member 4, reducing the friction between the pressing member 4 and the pressing section, thereby increasing the service life of the product and reducing the pressing force of the user on the pressing member 4, which is convenient for operation.

[0037] In this embodiment, the outer wall of the pressing member 4 is a concave arc surface. The pressing member 4 with an arc surface is more convenient for users to pick up and press.

[0038] In this embodiment, the side where the two clamping members 23 are close to each other is a convex arc surface. Because the widths of busbars 5 of different specifications are inconsistent, the clamping angles of the clamping swing arm 22 are also inconsistent. By setting the clamping surface of the clamping member 23 as an arc surface, the clamping is prevented from being not tightly clamped due to the inconsistent clamping angles of the clamping swing arm 22.

[0039] In this embodiment, the clamping member 23 is made of rubber material. The friction force of the clamping member 23 made of rubber material is relatively high, and even if the contact area between the clamping member 23 and the busbar 5 is relatively small, the clamping stability of the clamping member 23 can be ensured.

[0040] See also Figures 1 to 3 In one embodiment of the present invention, a slide bar 31 is fixed on the top of the positioning bar 3, a slide hole is opened at the bottom of the shell 1, the slide bar 31 is slidably set in the slide hole, and a return spring 32 is sleeved on the outer periphery of the slide bar 31, and the two ends of the return spring 32 abut the bottom surface of the positioning bar 3 and the shell 1.

[0041] With such an arrangement, when the positioning strip 3 presses and fixes the optical fiber 6, it has a certain buffering force, thereby avoiding damage to the optical fiber 6 caused by direct hard pressure, thereby ensuring the stability of the pressure and eliminating the need for a very precise clamping height during clamping. As long as the clamping position is within a certain height range, the optical fiber 6 can be clamped.

[0042] In this embodiment, a guide member 33 is fixed on the top of the positioning strip 3, a sliding opening is opened at the bottom of the shell 1, the guide member 33 is slidably arranged in the sliding opening along the vertical direction, the part of the guide member 33 located below the shell 1 is provided with a guide slope, and a guide strip 41 is provided on the bottom surface of the pressing member 4, the guide strip 41 is arranged toward the guide member 33, and a guide slope is provided at one end of the guide strip 41 toward the guide member 33. When the pressing member 4 is pressed to the bottom, the guide slope of the guide strip 41 pushes the guide slope of the pressing member 4 to squeeze the pressing member 4 upward. By setting the cooperation between the guide member 33 and the guide bar 41, when the worker presses the pressing member 4 to the bottom, the guide bar 41 squeezes the guide member 33 upward, and the guide member 33 drives the positioning bar 3 to move upward. At this time, there is a gap between the positioning bar 3 and the busbar 5, and the worker can free one hand to adjust the position of the optical fiber 6 so that it is facing the groove of the positioning bar 3. Then the worker releases the pressing member 4, and the inclined surface of the guide bar 41 is separated from the guide member 33. The positioning bar 3 is reset and squeezed downward by the action of the reset spring 32, and the optical fiber 6 is squeezed into the groove. The clamping member 23 clamps to both sides of the busbar 5 to complete the positioning and clamping operation. The operation is relatively simple and the positioning accuracy is high.

[0043] When the pressing member 4 is in a normal state, there is a gap between the guide bevel of the guide bar 41 and the guide member 33. Only when the pressing member 4 is pressed to the deepest position can the guide bar 41 push up the guide member 33. After the pressing member 4 is released, the guide bar 41 will be separated from the guide member 33, so that the positioning bar 3 is reset. At this time, the guide bar 41 continues to return to its original position. The travel from the guide bar 41 being separated from the guide member 33 to the guide bar 41 returning to its original position, and the corresponding clamping travel of the clamping member 23, is the width range of the busbar 5 that can be clamped by this solution.

[0044] In this embodiment, the guide member 33 includes a frame and a wedge-shaped block, the two sides of the frame are penetrated, the wedge-shaped block is installed on the top of the inner wall of the frame, and both sides of the wedge-shaped block are inclined surfaces. The guide member 33 is provided with a wedge-shaped block, and the guide strips 41 on both sides of the guide member 33 push the guide member 33 up at the same time, so that the pressing feel of the pressing members 4 on both sides is consistent.

[0045] The guide strips 41 at the bottom of the two pressing members 4 are staggered so as to avoid the guide strips 41 on both sides blocking each other during pressing.

[0046] See also Figures 1 to 3 In one embodiment of the present invention, the width of the groove of the positioning bar 3 is greater than the diameter of the optical fiber 6, the height of the groove of the positioning bar 3 is less than the diameter of the optical fiber 6, and both ends of the positioning bar 3 are flared structures. In this way, there is a slight offset error in the placement of the optical fiber 6, which facilitates the placement operation of the optical fiber 6.

[0047] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
