Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, specifically a fixing fixture for cable testing equipment. Background Technology

[0002] Cable is a transmission medium consisting of one or more insulated conductors (such as copper or aluminum) covered with an insulation layer and a sheath. It is widely used in power, communication, industrial control and other fields.

[0003] Cable testing (such as insulation resistance, withstand voltage testing, and signal transmission performance testing) requires clamping and fixing to achieve the following objectives: prevent cable slippage or detachment during testing, ensuring the accuracy of test data (e.g., avoiding cable displacement and discharge during high-voltage testing); isolate the cable from the external environment by fixing it (e.g., moisture and dust protection), reducing test interference; and the fixing fixture can disperse mechanical stress (e.g., tensile and torsional forces) during testing, avoiding cable damage or the risk of electric shock to personnel.

[0004] In scenarios such as cable performance testing, fault diagnosis, or quality inspection, traditional fixing fixtures typically use a method of fixing one cable at a time, requiring manual adjustment of the clamp size or replacement of specific clamp specifications to accommodate cables of different diameters. This operating mode has significant drawbacks: on the one hand, single-cable testing is inefficient and cannot meet the needs of batch testing; on the other hand, frequent clamp changes increase operational complexity and are prone to insecure fixing or cable damage due to human error. Furthermore, traditional fixtures usually lack support for parallel fixing of multiple cables, making it difficult to cope with the need for simultaneous testing of multiple cables in complex testing scenarios. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a fixing fixture for cable testing devices, which has advantages such as good adaptability and the ability to clamp multiple cables simultaneously, thus solving the problems of low working efficiency and poor adaptability of existing clamping fixtures.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fixing fixture for a cable testing device, comprising a mounting base, characterized in that: the mounting base is provided with a support block and a mounting platform for installation, two connecting members are provided between the support block and the mounting platform, a transmission block for transmission and a plurality of clamping blocks for clamping cables are slidably connected between the two connecting members, and a clearance groove is provided on the back of the support block to facilitate cable passage.

[0007] The mounting platform is provided with a linkage component for transmitting power to the transmission block, and the mounting base is provided with a transmission component for driving the linkage component.

[0008] The linkage component includes a connecting screw threaded to the mounting platform. One end of the connecting screw contacts the transmission block, and the other end is fixedly connected to the connecting platform. A linkage gear for linkage is connected to the connecting platform.

[0009] The transmission component includes a transmission gear rotatably connected to the mounting base. The transmission gear meshes with the linkage gear. A fixing seat for fixing is installed on one side of the transmission gear. A transmission lever for easy adjustment by the operator is provided on the fixing seat.

[0010] Furthermore, the connector includes a connecting seat and a connecting bolt. The connecting seat is mounted on the mounting base by the connecting bolt. The connecting seat has a limiting groove for limiting the position, and a sliding space is formed between the limiting groove and the mounting base.

[0011] Furthermore, the mounting base is also provided with a plurality of positioning posts for positioning, and the connecting base is provided with positioning holes that match the number of posts, and the positioning posts are inserted into the positioning holes.

[0012] Furthermore, the clamping block is provided with clamping grooves for accommodating cables of different sizes, and the clamping grooves are trapezoidal grooves.

[0013] Furthermore, a reset spring for resetting is provided between the transmission block and the clamping block.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] I. This fixing fixture for cable testing equipment, through the setting of linkage and transmission components, can effectively control the clamping block and transmission block during use, thereby achieving the effect of quickly controlling the transmission block and clamping block to clamp and fix the cable; by setting multiple transmission blocks, it can effectively fix multiple cables during use, thereby improving the work efficiency in the cable fixing process.

[0016] Second, the fixing fixture used for cable testing equipment is equipped with a return spring, which enables it to effectively reset the transmission block and clamping block during use, ensuring the continuity of clamping work and increasing its work efficiency. Attached Figure Description

[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] Example 1:

[0023] Please see Figure 1-3 This embodiment provides a fixing fixture for a cable testing device, including a mounting base 1, a mounting block with a support block 11 and a mounting platform 12, two connecting members 13 between the support block 11 and the mounting platform 12, a transmission block 14 for transmission and multiple clamping blocks 15 for clamping cables slidably connected between the two connecting members 13, and a clearance groove 17 for cable passage on the back of the support block 11; the mounting platform 12 is provided with a linkage member 2 for transmitting power to the transmission block 14, and the mounting base 1 is provided with a linkage member 2 for connecting the transmission block 14. The transmission component 3 drives the moving component 2; the linkage component 2 includes a connecting screw 21 threadedly connected to the mounting base 12, one end of the connecting screw 21 is in contact with the transmission block 14, and the other end is fixedly connected to the connecting platform 22, on which a linkage gear 23 for linkage is connected; the transmission component 3 includes a transmission gear 31 rotatably connected to the mounting base 1, the transmission gear 31 meshes with the linkage gear 23, and a fixing seat 32 for fixing is installed on one side of the transmission gear 31, and a transmission lever 33 for easy adjustment by the operator is provided on the fixing seat 32.

[0024] In actual use, the operator inserts the cable to be tested into multiple transmission blocks 14 and between the transmission blocks 14 and the clamping blocks 15. Then, the operator controls the transmission lever 33 to make the fixed base 32 rotate. During the rotation of the fixed base 32, the transmission gear 31 is driven to rotate. During the rotation of the transmission gear 31, the linkage gear 23 is driven to rotate. When the linkage gear 23 rotates, the connecting platform 22 and the connecting screw 21 are driven to rotate. During the rotation of the connecting screw 21, a forward displacement effect is generated. At this time, the transmission blocks 14 and multiple clamping blocks 15 are driven to move closer together, thereby achieving the effect of clamping and fixing the cable. After clamping, the operator can control the transmission lever 33 to rotate in the opposite direction, thereby driving the linkage gear 23 to retract. At this time, the cable fixing is canceled, and the operator can remove the cable to fix another batch.

[0025] The technical effects of the above embodiments are as follows: by setting the linkage 2 and the transmission 3, the clamping block 15 and the transmission block 14 can be effectively controlled during use, thereby achieving the effect of quickly controlling the transmission block 14 and the clamping block 15 to clamp and fix the cable; by setting multiple transmission blocks 14, multiple cables can be effectively fixed during use, thereby improving the work efficiency in the process of fixing cables.

[0026] As a preferred technical solution in this embodiment: the connector 13 includes a connector 131 and a connecting bolt 133 symmetrically arranged along the transverse centerline of the mounting base 1. The connector 131 is mounted on the mounting base 1 by the connecting bolt 133. A limiting groove 132 for limiting is provided on the connector 131, and a sliding space is formed between the limiting groove 132 and the mounting base 1. This connection method can effectively ensure that it can be easily installed and removed during use. By providing a limiting groove 132 for limiting on the connector 131, it can effectively limit the transmission block 14 and the clamping block 15 during use, ensuring its stability during use.

[0027] As a preferred technical solution in this embodiment: the mounting base 1 is further provided with a plurality of positioning posts 16 for positioning, and the connecting base 131 is provided with positioning holes 134 adapted to its number, with the positioning posts 16 and positioning holes 134 interlocking. By providing positioning holes 134 and positioning posts 16, the connecting base 131 can be effectively positioned during use, ensuring its stability during installation and preventing the connecting base 131 from tilting, thereby ensuring the stability of the transmission block 14 and the clamping block 15 during sliding and increasing its usability.

[0028] As a preferred technical solution in this embodiment, the clamping block 15 is provided with clamping grooves for accommodating cables of different sizes. The clamping grooves are trapezoidal. By setting them as trapezoidal grooves, they can simultaneously achieve a good clamping and fixing effect on multiple cables of different diameters during use, ensuring their stability during use.

[0029] As a preferred technical solution in this embodiment: both the transmission block 14 and the clamping block 15 are provided with limiting blocks that are slidably connected to the positioning hole 134, and both the transmission block 14 and the clamping block 15 are provided with a reset spring 18 for resetting. By providing a reset spring 18, the transmission block 14 and the clamping block 15 can be effectively reset during use; specifically, when the operator controls the transmission block 14 and the clamping block 15 to clamp the cable, the reset spring 18 is compressed by force, and when the control connecting screw 21 is released, the spring will push up the transmission block 14 and the clamping block 15 to achieve the reset effect.
