[0035] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the embodiments. It should be understood that the embodiments are only for explaining the present invention and are not intended to limit it.

[0036] Example 1 like Figure 1-11 As shown, this embodiment provides a cable clamp in a screen cabinet, which includes a mounting plate 1 and two blocking plates 2 tightly attached to the two side surfaces of the mounting plate 1, a plurality of placement holes 5 are provided on the blocking plate 2 corresponding to the mounting holes, the mounting plate 1 is formed by splicing a center plate 102 and two side plates 101, and the two side plates 101 are spliced ​​on both sides of the center plate 102; a plurality of grooves are provided on the center plate 102 and the side plates 101 at the splicing parts, the grooves on the center plate 102 and the grooves on the side plates 101 together form a mounting hole, and the mounting hole is provided with a detachable clamping ring 6 for clamping and fixing the cable 3.

[0037] When in use, the staff uses the clamping ring 6 to clamp the cable 3, places it in the groove, and splices the mounting plate 1 so that the clamping ring 6 is placed in the mounting hole, and then uses two blocking plates 2 to install it tightly against the mounting plate 1. The diameter of the prevention hole 3 on the blocking plate 2 is smaller than the diameter of the mounting hole. The clamping ring 6 in the mounting hole can be limited to prevent it from slipping out of the mounting hole, so as to achieve reliable fixation of multiple cables 3. At the same time, the installation steps are simple, which can improve the installation efficiency.

[0038] In this embodiment, a plurality of insertion holes 12 penetrating the mounting plate 1 and the barrier plate 2 are provided on the cable clamp in the panel cabinet, an insertion rod 11 is provided in the insertion hole 12, and nuts for clamping the mounting plate 1 and the two barrier plates 2 are provided at both ends of the insertion rod 11.

[0039] In order to simplify the structure and enhance the overall strength, four insertion holes 12 can be set at the four corners of the entire mounting plate, that is, two insertion holes 12 are set at the two corners of the side plate 101 away from the center plate 102, and multiple insertion holes 12 can also be set, which is not limited here. When the staff installs and uses the cable clamp, when installing two baffle plates 2 close to the mounting plate 1, they can first insert the insertion rod 11 into the insertion hole 12 on the mounting plate 1, and then insert the insertion hole 12 on the baffle plate 2 and the insertion hole 12 at the corresponding position on the mounting plate 1 into the insertion rod 11, and then install nuts on both ends of the insertion rod 11, and tighten the nuts to ensure that the two baffle plates 2 clamp the mounting plate.

[0040] Through this embodiment, the two side panels 101 can be tightened by the blocking plate 2, the insertion rod 11 and the insertion hole 12 to ensure the stability of the overall installation of the mounting plate 1.

[0041] In this embodiment, the clamping ring 6 includes a first clamping arc block 601 detachably disposed in a groove of the side plate 101 , and a second clamping arc block 602 detachably disposed in a groove of the center plate 102 .

[0042] Through this embodiment, the clamping ring 6 is set as the first clamping arc block 601 and the second clamping arc block 602, and they are detachably arranged in the side plate 101 and the center plate 102 respectively. When using and installing this cable clamp, the first clamping arc block 601 and the second clamping arc block 602 can be used to initially clamp the cable, and then the center plate 102 and the two side plates 101 are spliced. In this way, when using and installing, it is beneficial to avoid damage to the cable while ensuring that the clamping ring 6 tightly holds and fixes the cable 3, and it is convenient for installation or disassembly. The flexibility of the design of the clamping structure is enhanced through the cooperation of the groove with the first clamping arc block 601 and the second clamping arc block 602.

[0043] In this embodiment, the first clamping arc block 601 and the second clamping arc block 602 are provided in various models, and the outer diameters of the clamping ring 6 composed of the first clamping arc blocks 601 and the second clamping arc blocks 602 of different models are the same.

[0044] The sizes of multiple cables 3 may be different. The first clamping arc block 601 and the second clamping arc block 602 are set to multiple models. When using the cable clamp, the staff can select different models of first clamping arc blocks 601 and second clamping arc blocks 602 according to cables 3 of different sizes to ensure the stability of clamping and fixation; the outer diameters of the clamping ring 6 composed of different models of first clamping arc blocks 601 and second clamping arc blocks 602 are the same, so that the different clamping rings 6 composed of them can be universally installed in the same mounting holes, so all the mounting holes can be set to the same diameter, and the placement holes 5 on the baffle plate can also be set to the same diameter, which simplifies the component management and replacement process.

[0045] In this embodiment, a clamping hole for fixing the cable 3 is provided in the clamping ring 6, and the sizes of the clamping holes of the clamping ring 6 composed of the first clamping arc block 601 and the second clamping arc block 602 of different models are different.

[0046] Through this embodiment, the installation requirements of cables 3 with different diameters can be met to improve the adaptability of the cable clamp.

[0047] In this embodiment, an annular embedding groove 17 with an L-shaped cross section is respectively provided on the inner walls at both ends of the clamping hole, and a deep-entry ring 8 is provided in the embedding groove 17 .

[0048] During installation and use, the first clamping arc block 601 and the second clamping arc block 602 can be further fixed by inserting the ring 8 into the embedding groove 17, so as to provide further fixing support for the cable 3 and provide a buffering effect when the cable 3 is subjected to external force.

[0049] In this embodiment, a plurality of through sliding grooves 20 are provided on the side wall of the penetration ring 8 , and a slidable pressing block 9 is provided in the sliding groove 20 .

[0050] Taking into account that during use, the sizes of the cable 3 are various, such as the cable sizes with apertures of 4.9 cm and 4.8 cm. Although these diameters are different, the changes are relatively small. If the apertures of the first clamping arc block 601 and the second clamping arc block 602 with different apertures are too fine, although they can correspond to slight changes in the sizes of different pairs of cables 3, this will undoubtedly increase the manufacturing cost and increase the difficulty in size selection. If only a few sizes are set, it is difficult to ensure the stability of the first clamping arc block 601 and the second clamping arc block 602 in clamping the cable.

[0051] The end of the clamping block 9 in the sliding groove 20 away from the mounting hole is set to a slope with a certain angle. Therefore, after the deep ring 8 enters the embedded groove 17, the clamping block 9 in the sliding groove 20 will slide in contact with the embedded groove 17, pushing the clamping block 9 in the direction of the cable, thereby stably clamping the cable. Through the design of the clamping block 9, the fixing force of the clamping ring on the cable 3 is further enhanced, ensuring the stability of the cable 3 in long-term use, expanding the clamping size range of the clamping ring 6, and reducing the manufacturing cost of the device.

[0052] In this embodiment, an annular plate 7 is provided on the outer side wall of the penetration ring 8 ; and a receiving groove 13 for receiving the annular plate 7 is provided on a side of the blocking plate 2 that is in contact with the mounting plate 1 .

[0053] The side surface of the annular plate 7 away from the mounting plate 1 is flush with the outer side surface of the blocking plate 2 away from the mounting plate 1. Through the cooperation between the annular plate 7 and the accommodating groove, the stability between the clamping ring 6 and the blocking plate 2 can be further enhanced to further increase the overall strength and stability of the device.

[0054] In this embodiment, a threaded member 19 is provided at the edge of the annular plate 7 on one side close to the mounting plate 1 , and a threaded ring 14 which can be threadedly connected to the threaded member 19 is provided in the receiving groove 13 .

[0055] The penetration ring 8, the clamping block 9 and the annular plate 7 together constitute a clamping member. The threaded ring 14 that can be threadedly connected to the threaded member 19 is arranged in the accommodating groove 13, so that the clamping member can be threadedly connected to the blocking plate 2 as a whole, so as to enhance the stability between the blocking plate 2, the mounting plate 1 and the clamping ring 6. During the installation process, the clamping member can be first installed as a whole on the blocking plate 2, and then when the blocking plate 2 and the mounting plate 1 are combined, the penetration ring 8 on the blocking plate 2 is embedded in the embedding groove 17. At this time, the clamping block 9 on the penetration ring 8 moves to a suitable position in the sliding groove 20 to complete the limited fixation of the cable. At the same time, since the blocking plate 2 and the mounting plate 1 are fixed by the insertion rod 11 and the insertion hole 12, the accurate combination between the blocking plate 2 and the mounting plate 1 can be ensured, which makes it possible to ensure that the penetration ring 8 and the embedding groove 17 are accurately docked when multiple penetration rings 8 are pushed into the embedding groove 17 through the blocking plate 2, which can not only achieve the clamping of multiple cables, but also facilitate fixation.

[0056] In this embodiment, the outer side walls at both ends of the clamping ring 6 are provided with thread grooves 18 which can be threadably matched with the threaded member 19 .

[0057] Due to the need to adapt to a variety of cables 3 of different sizes, the first clamping arc block 601 and the second clamping arc block 602 also need to be set to a variety of different models. In addition, when fixing the cable, the staff also needs to select a clamping piece that matches the inner diameter of the first clamping arc block 601 and the second clamping arc block 602. Therefore, when storing the first clamping arc block 601, the second clamping arc block 602 and the clamping piece, the first clamping arc block 601 and the second clamping arc block 602 can be spliced ​​together, and then the threaded member 19 on the clamping piece is screwed into the thread groove 18 to splice and fix the first clamping arc block 601, the second clamping arc block 602 and the clamping piece together. While facilitating storage and sorting, it is also convenient for the staff to quickly find the first clamping arc block 601 and the second clamping arc block 602 of the same model when selecting the clamping ring 6, which can not only improve the efficiency of installation, but also avoid the loss of parts.

[0058] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on one or several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.

The embodiments shown in the embodiments are only part of the implementation methods of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the embodiments and designs a structure and an implementation method similar to the technical solution without creativity without departing from the purpose of the invention, they should all fall within the protection scope of the present invention.
