Detailed Embodiments

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0025] Embodiment 1

[0026] Figure 1 This is a schematic perspective view of the cable clamping device of the present utility model. Refer to Figure 1 As shown, the cable clamping device includes an adjusting mechanism, a controller 2, and a clamping mechanism with adjustable inner diameter. The clamping mechanism with adjustable inner diameter is shown in Figure 2 as follows.

[0027] In this embodiment, the adjusting mechanism includes a base 1, and the base 1 can be selected as a rectangular base 1; a groove 3 is formed on the base 1. The groove 3 can be formed along the length direction of the rectangular base 1 or along the width direction of the rectangular base 1. In one implementation manner of this embodiment, there are two groups of grooves 3, and both groups of grooves 3 are formed along the length direction of the rectangular base 1 and are arranged in parallel at intervals, and the clamping mechanism is arranged between the two groups of grooves 3.

[0028] Furthermore, a first driving motor 4 is provided on one side of the groove 3. The first driving motor 4 is electrically connected to the controller 2. Preferably, the output shaft of the first driving motor 4 penetrates through the side wall of the base 1 and extends into the groove 3. In this embodiment, the first driving motor 4 is only provided on one side of one of the two groups of grooves 3, and the two clamping mechanisms are driven by this first driving motor 4 to displace simultaneously.

[0029] Specifically, a first screw rod 5 connected to the output shaft of the first driving motor 4 is provided in the groove 3. The first screw rod 5 is composed of a first thread section and a second thread section with opposite threads. A first driving block 8 is threadedly connected to the first thread section, and a second driving block is threadedly connected to the second thread section; when the first screw rod 5 rotates, the first screw rod 5 will drive the first driving block 8 and the second driving block to displace towards each other or away from each other according to its rotation direction. Refer to Figure 3 and Figure 4 As shown, in this embodiment, the tops of the first driving block 8 and the second driving block are respectively connected with a clamping mechanism. Thus, by driving the first screw rod 5 to rotate through the controller 2, the first screw rod 5 drives the first driving block 8 and the second driving block to displace towards each other or away from each other, so as to realize the adjustment of the distance between the clamping mechanisms, meet different clamping requirements of the cable, and ensure the stability of cable clamping.

[0030] Embodiment 2

[0031] Based on the technical solution of Embodiment 1, this embodiment further describes the clamping mechanism:

[0032] In this embodiment, refer to Figure 6As shown, the clamping mechanism includes a collar 10, and a number of tightening members are arranged at radial intervals of the collar 10; in this embodiment, by arranging a number of tightening members at radial intervals of the collar 10, and through the change of the overall length of the tightening members, the inner diameter of the clamping mechanism is adjusted accordingly to adapt to cables of different specifications.

[0033] Specifically, in a possible implementation manner, the tightening member is composed of a gear section 21, a limiting section 20, and a fixing section 26 connected in sequence. A limiting groove 19 is formed in the side wall of the collar 10, and the limiting section 20 is arranged in the limiting groove 19 and is in clearance fit with the limiting groove 19; preferably, inner and outer grooves 18 are also formed on the inner and outer surfaces of the collar 10, and the inner groove 18 is communicated with the limiting groove 19 to form a limiting space that is large inside and small on both sides. Limiting rings 22 are arranged on the front and rear sides of the limiting section 20, and the limiting rings 22 are fixedly connected to the limiting section 20 and are in clearance fit with the inner groove 18.

[0034] See Figure 5 As shown, the gear section 21 is arranged outside the collar 10 and is fixedly connected to the limiting section 20. The gear section 21 is configured to rotate under the drive of a transmission mechanism; the fixing section 26 is arranged inside the collar 10 and is fixedly connected to the inner wall of the collar 10; a second screw 23 is connected to the gear section 21 and the limiting section 20 in an axial threaded manner, and a push rod 25 is connected to the fixing section 26 in an axial sliding manner. One end of the second screw 23 adjacent to the push rod 25 is fixedly connected; a fixing key 28 is arranged on the outside of the push rod 25, and a key groove 27 is formed in the fixing section 26 corresponding to the fixing key 28, so that the push rod 25 can only linearly displace along the axial direction of the fixing section 26; when the gear section 21 rotates under the drive of the transmission mechanism, since one end of the second screw 23 adjacent to the push rod 25 is fixedly connected, the second screw 23 linearly displaces towards or away from the axial direction of the collar 10 according to the rotation direction of the gear section 21, thereby pushing or pulling the push rod 25 to displace, and thus the inner diameter of the clamping mechanism can be changed. In addition, to prevent the second screw 23 from entirely entering the inner groove 18, a baffle 24 is arranged at one end of the second screw 23 away from the push rod 25, and the diameter of the baffle 24 is larger than that of the inner groove 18; to further improve the stability of the cable, a first support portion 29 is arranged at one end of the push rod 25 away from the second screw 23, and the end surface of the first support portion 29 close to the collar 10 can be an arc-shaped end surface to fit the outer surface of the cable and enhance the clamping stability.

[0035] Embodiment 3

[0036] Based on the technical solution of Embodiment 2, this embodiment further describes the transmission mechanism:

[0037] In this embodiment, the transmission mechanism includes a bevel gear ring 15 rotatably mounted on one side of the collar 10 and coaxially arranged with the collar 10. The bevel gear ring 15 has a first tooth surface 17 meshing with the gear segment 21 and a second tooth surface 16 meshing with the output shaft of the second drive motor 12. The second drive motor 12 is electrically connected to the controller 2. The bevel gear ring 15 is configured to rotate under the drive of the power gear 14 on the output shaft of the second drive motor 12. When the bevel gear ring 15 rotates under the drive of the second drive motor 12, the first tooth surface 17 of the bevel gear ring 15 drives the gear segment 21 to rotate, thereby adjusting the inner diameter of the clamping mechanism.

[0038] More specifically, the tops of the first drive block 8 and the second drive block are both connected to the clamping mechanism through a first mounting bracket 9. The first mounting bracket 9 can be an "L"-shaped bracket. The first end of the "L"-shaped bracket is fixedly connected to the side wall of the collar 10, and the second end of the "L"-shaped bracket is fixedly connected to the top of the corresponding first drive block 8 or the second drive block. The second drive motor 12 is arranged on the first mounting bracket 9 through a second mounting bracket 11.

[0039] Embodiment 4

[0040] Based on the technical solution of Embodiment 1, this embodiment provides a support mechanism between the two clamping mechanisms. The support mechanism includes an electric push rod 6 arranged on the base 1. The output end of the electric push rod 6 is connected with a second support portion 7. The electric push rod 6 is electrically connected to the controller 2. In this embodiment, the controller 2 controls the extension length of the output shaft of the electric push rod 6, thereby adjusting the height of the second support portion 7 to adapt to the support of the middle position of different specifications of cables when clamped by the clamping mechanisms at both ends, which can further improve the stability of cable clamping.

[0041] Working principle: Before clamping the cable to be clamped, the first drive motor 4 is started through the controller 2, so that the first screw rod 5 rotates. The distance between the two clamping mechanisms is adjusted through the first screw rod 5 to adjust the distance between the two clamping mechanisms to a suitable clamping distance. After the distance between the two clamping mechanisms is adjusted, the second drive motor 12 is started through the controller 2, so that the bevel gear ring 15 rotates. The gear segment 21 on the tightening member is driven to rotate by the bevel gear ring 15, and the first support portion 29 is driven to displace towards the axis of the collar 10 to clamp and fix the cable to be clamped located within the collar 10. At the same time, the electric push rod 6 is started through the controller 2, so that the electric push rod 6 drives the second support portion 7 to displace to support the middle part of the cable clamped between the two clamping mechanisms, thereby realizing the clamping and support of the cable.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
