Description

Technical Field

[0001] This utility model relates to the field of optical cable clamp technology, and more specifically, to an optical cable tensile strength testing clamp. Background Technology

[0002] Optical fiber cable is a type of cable composed of numerous optical fibers, used for the efficient transmission of optical signals. In the construction of communication networks, optical fiber cables come in a wide variety of specifications and have significant differences in thickness. Different application scenarios have different requirements for the thickness of optical fiber cables. In actual use, optical fiber cables need to withstand various external forces, so tensile strength has become a key indicator for measuring their quality and performance. This requires the use of clamps to hold and fix the optical fiber cables.

[0003] Traditional optical cable tensile strength testing fixtures have revealed many limitations in practical applications. When faced with optical cables of varying thicknesses, traditional fixtures struggle to achieve precise and efficient clamping. When testing two optical cables of the same specification simultaneously, it is difficult to ensure consistent clamping force and position, leading to significant deviations in test results. If the optical cables have large differences in thickness, or if specific thicknesses of optical cables require clamping tests at special positions, traditional fixtures are even more inadequate and cannot flexibly meet diverse testing needs. This inflexible clamping method greatly reduces fixing efficiency and severely limits the accuracy and comprehensiveness of testing, making it difficult to effectively guarantee the quality and efficiency of optical cable tensile strength testing.

[0004] Therefore, there is an urgent need for a fixture for testing the tensile strength of optical cables to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a clamp for testing the tensile strength of optical cables to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A clamp for testing the tensile strength of optical cables includes a connecting plate, a mounting bracket fixedly connected to the top wall of the connecting plate, symmetrically distributed sliders fixedly connected to the outer wall of the mounting bracket, and a mounting base fixedly connected to the outer wall of the connecting plate. The clamp also includes:

[0008] The freely adjustable assembly includes a support plate fixedly connected to the top wall of the mounting frame, a guide block fixedly connected to the outer wall of the support plate, a guide groove formed on the outer wall of the guide block, symmetrically distributed extension grooves formed on the inner wall of the guide groove, a guide sleeve slidably connected to the inner wall of the guide groove, a drive rod rotatably connected to the outer wall of the guide sleeve, a drive gear fixedly connected to the outer wall of the drive rod, and a knob fixedly connected to the top wall of the drive rod.

[0009] Adaptive components are mounted on the outer wall of the guide block;

[0010] A clamping assembly is disposed on the outer wall of the mounting frame, and the clamping assembly cooperates with the free adjustment assembly.

[0011] As a preferred technical solution of this application, the adaptive component includes a rotating plate rotatably connected to the outer wall of the guide block, a telescopic rod rotatably connected to the outer wall of the rotating plate, and the end of the telescopic rod away from the rotating plate being rotatably connected to the guide sleeve. A strong spring is sleeved on the outer wall of the telescopic rod, and the strong spring is fixedly connected to the rotating plate. The end of the strong spring away from the rotating plate is fixedly connected to the guide sleeve.

[0012] As a preferred technical solution of this application, the clamping assembly includes a bidirectional screw symmetrically rotatably connected to the outer wall of the mounting bracket, and the thread directions of the bidirectional screw are all the same. The outer wall of the bidirectional screw is threaded with symmetrically distributed clamping blocks, and the clamping blocks are slidably connected to the slider. The outer wall of the clamping blocks is fixedly connected with uniformly distributed anti-slip protrusions. The top wall of the bidirectional screw is fixedly connected with a linkage gear, and the outer wall of the linkage gear is meshed with the outer wall of the drive gear.

[0013] As a preferred technical solution of this application, the inner wall of the guide groove is rotatably connected with symmetrically distributed auxiliary rotating rods, and the outer wall of the auxiliary rotating rods abuts against the outer wall of the guide sleeve.

[0014] As a preferred technical solution of this application, the outer wall of the mounting frame is fixedly connected with symmetrically distributed guide rods, and the guide rods are slidably connected to the clamping block.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] 1. The position of the drive gear can be freely adjusted to adapt to various optical cable testing needs. When testing two optical cables of the same specification, the guide sleeve is adjusted so that the drive gear simultaneously engages two linkage gears. Turning the knob causes two bidirectional screws to synchronously drive the clamping blocks, achieving synchronous clamping. If the optical cables have different specifications or require special clamping, the strong spring and rotating plate in the adaptive component work together to allow the drive gear to engage a single linkage gear, controlling the adjustment of the corresponding clamping block independently. This greatly improves the versatility and flexibility of the fixture, increases fixing efficiency, and solves the problem that the existing technology cannot flexibly cope with diverse testing needs. This inflexible clamping method greatly reduces fixing efficiency, seriously limits the accuracy and comprehensiveness of testing, and makes it difficult to effectively guarantee the quality and efficiency of optical cable tensile strength testing.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0027] like Figure 1-6 As shown, the optical cable tensile strength testing fixture proposed in this embodiment includes a connecting plate 1, a mounting bracket 3 fixedly connected to the top wall of the connecting plate 1, symmetrically distributed sliders 6 fixedly connected to the outer wall of the mounting bracket 3, and a mounting base 2 fixedly connected to the outer wall of the connecting plate 1. It also includes:

[0028] The freely adjustable assembly includes a support plate 11 fixedly connected to the top wall of the mounting bracket 3. A guide block 12 is fixedly connected to the outer wall of the support plate 11. A guide groove 19 is opened on the outer wall of the guide block 12. A symmetrically distributed extension groove 20 is opened on the inner wall of the guide groove 19. A guide sleeve 13 is slidably connected to the inner wall of the guide groove 19. A drive rod 14 is rotatably connected to the outer wall of the guide sleeve 13. A drive gear 10 is fixedly connected to the outer wall of the drive rod 14. A knob 15 is fixedly connected to the top wall of the drive rod 14. When adjustment is required, the knob 15 is rotated, which drives the drive rod 14 to rotate. When the drive rod 14 rotates, the drive gear 10 rotates accordingly. At the same time, the rotation of the drive rod 14 causes the guide sleeve 13 to slide in the guide groove 19. When the position of the drive gear 10 is adjusted, if the drive gear 10 meshes with one of the linkage gears 5, rotating the knob 15 will drive the drive gear 10 to rotate. The linkage gear 5 that the drive gear 10 meshes with is different at different positions.

[0029] An adaptive component is disposed on the outer wall of guide block 12;

[0030] The clamping assembly is located on the outer wall of the mounting bracket 3, and the clamping assembly cooperates with the free adjustment assembly.

[0031] like Figure 5 As shown, in a preferred embodiment, based on the above method, the adaptive component further includes a rotating plate 18 rotatably connected to the outer wall of the guide block 12. A telescopic rod 16 is rotatably connected to the outer wall of the rotating plate 18, and the end of the telescopic rod 16 away from the rotating plate 18 is rotatably connected to the guide sleeve 13. A strong spring 17 is sleeved on the outer wall of the telescopic rod 16, and the strong spring 17 is fixedly connected to the rotating plate 18. The end of the strong spring 17 away from the rotating plate 18 is fixedly connected to the guide sleeve 13. When the guide sleeve 13 slides, it will drive the telescopic rod 16 to move, and the telescopic rod 16 will drive the rotating plate 18 to rotate. Since the guide sleeve 13 can slide in the guide groove 19, the position of the drive gear 10 can be freely adjusted. During the sliding process of the guide sleeve 13, the strong spring 17 on the outer wall of the telescopic rod 16 plays the role of self-adaptation of the guide sleeve 13. When the guide sleeve 13 is moved by external force, the strong spring 17 can extend and retract, so that the rotating plate 18 can adaptively adjust the angle, ensuring the smoothness of the entire adjustment process, while the drive gear 10 can always mesh with the linkage gear 5 after the adjustment position.

[0032] like Figure 3As shown, in a preferred embodiment, based on the above method, the clamping assembly further includes a bidirectional screw 4 symmetrically rotatably connected to the outer wall of the mounting bracket 3, with all threads of the bidirectional screw 4 having the same direction. Symmetrically distributed clamping blocks 7 are threadedly connected to the outer wall of the bidirectional screw 4, and the clamping blocks 7 are slidably connected to the slider 6. Uniformly distributed anti-slip protrusions 9 are fixedly connected to the outer wall of the clamping blocks 7. A linkage gear 5 is fixedly connected to the top wall of the bidirectional screw 4, and the outer wall of the linkage gear 5 meshes with the outer wall of the drive gear 10. The linkage gear 5 drives the bidirectional screw 4 to rotate. Because the threads of the bidirectional screw 4 have the same direction, the symmetrically distributed clamping blocks 7 will move towards or away from each other under the drive of the bidirectional screw 4. During the movement, the clamping blocks 7 clamp the optical cable through the anti-slip protrusions 9 on their outer walls. Simultaneously, the clamping blocks 7, constrained by the slider 6 and the guide rod 8, can only move in a straight line, ensuring clamping stability. If the drive gear 10 meshes with the two linkage gears 5 at the same time, turning the knob 15 can make the two bidirectional screws 4 rotate synchronously, so that the clamps 7 on the two mounting brackets 3 can clamp the optical cable synchronously.

[0033] like Figure 6 As shown, in a preferred embodiment, based on the above method, the inner wall of the guide groove 19 is further rotatably connected with symmetrically distributed auxiliary rotating rods 21, and the outer wall of the auxiliary rotating rods 21 abuts against the outer wall of the guide sleeve 13. When the guide sleeve 13 slides, the auxiliary rotating rods 21 can reduce the friction between the guide sleeve 13 and the inner wall of the guide groove 19, making the sliding of the guide sleeve 13 smoother.

[0034] like Figure 2 As shown, in a preferred embodiment, based on the above method, the outer wall of the mounting frame 3 is further provided with symmetrically distributed guide rods 8, and the guide rods 8 are slidably connected to the clamping block 7. The guide rods 8 assist the clamping block 7 in sliding and improve the stability of the clamping block 7 in the direction of movement.

[0035] Specifically, when using this optical cable tensile strength testing fixture: When adjustment is required, turn knob 15. Knob 15 drives drive rod 14 to rotate. When drive rod 14 rotates, drive gear 10 rotates accordingly. Simultaneously, the rotation of drive rod 14 causes guide sleeve 13 to slide within guide groove 19. As guide sleeve 13 slides, it drives telescopic rod 16 to move, which in turn drives rotating plate 18 to rotate. Since guide sleeve 13 can slide within guide groove 19, the position of drive gear 10 can be freely adjusted. During the sliding process of guide sleeve 13, the strong spring 17 on the outer wall of telescopic rod 16 plays an adaptive role for guide sleeve 13. When guide sleeve 13 moves under external force, the strong spring 17... The telescopic mechanism 7 allows the rotating plate 18 to adaptively adjust its angle, ensuring smooth adjustment while the drive gear 10 always engages with the linkage gear 5 after adjustment. Once the drive gear 10 is in position, if it engages with one of the linkage gears 5, rotating the knob 15 causes the drive gear 10 to rotate the linkage gear 5. The linkage gear 5 engaged by the drive gear 10 varies depending on its position. The linkage gear 5 drives the bidirectional screw 4 to rotate. Because the threads of the bidirectional screw 4 are in the same direction, the symmetrically distributed clamping blocks 7 move towards or away from each other under the influence of the bidirectional screw 4. During movement, the clamping blocks 7 hold the optical cable using the anti-slip protrusions 9 on their outer walls. Simultaneously, the clamping blocks 7, constrained by the slider 6 and guide rod 8, can only move in a straight line, ensuring clamping stability. If the drive gear 10 engages with both linkage gears 5 simultaneously, rotating the knob 15 allows the two bidirectional screws 4 to rotate synchronously, thus enabling the clamping blocks 7 on both mounting brackets 3 to clamp the optical cable synchronously.

[0036] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
