[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1

[0026] like Figure 1 As shown, in this example, a cable clamp comprises a first clamp body 1, a second clamp body 2, and a fastener 4. The first clamp body 1 and the second clamp body 2 are arranged on the upper and lower parts and are connected and fixed as a whole by the fastener 4.

[0027] In this example, a groove 3 is formed between the facing surfaces of the first clamp 1 and the second clamp 2, that is, the bottom surface of the first clamp 1 at the top and the top surface of the second clamp 2 at the bottom, and a wire hole 8 is formed between the upper and lower opposite grooves 3. The specific shapes of the first clamp and the second clamp are not limited, such as Figure 1 As shown, the grooves formed on the bottom surface of the strip board correspond to each other to form the first clamping body and the second clamping body. Of course, irregular shaped plates can also be selected according to needs.

[0028] The corresponding grooves 1-3 are formed at intervals along the length direction of the first clamp 1 and the second clamp 2 (i.e., the lateral direction in the figure), and the grooves 1-3 extend along the width direction of the clamp, that is, multiple wire holes 1-8 are distributed in the lateral direction as shown in the figure, and multiple cables can be clamped side by side. This configuration helps to reduce the lateral length. Of course, in special environments, the grooves 1 can also be distributed at intervals along the width direction of the clamp, depending on the needs. Under this configuration, the first clamp and the second clamp are easy to form and have better performance.

[0029] In this example, the first clamp body 1 and the second clamp body 2 are connected at both ends by a fastener 4. Figure 1As shown, the first clamp body 1 and the second clamp body 2 are connected at both ends in the length direction by fasteners 4. Specifically, fasteners 4 are installed at both ends of the first clamp body 1 and the second clamp body 2, such as bolts. Holes are formed at both ends of the first clamp body 1 and the second clamp body 2, and bolts are used as fasteners to pass through the hole of one clamp body and are threadedly connected with the hole of the other clamp body. Or, fasteners 1 are composed of matching bolts and nuts, and bolts are passed through the holes at the ends of the first clamp body and the second clamp body and then fastened with nuts. Of course, fasteners 1 can also select buckle or embedded column structures according to needs, such as integrally formed at the end of the first clamp body, forming a matching slot or embedded hole at the end of the first clamp body, etc. In addition, fasteners 1 can also be installed between two grooves 1.

[0030] In this example, a third clamp body 6 and a second fastener 7 are added, such as Figure 1 As shown, the top surface of the first clamp body 1 at the top is connected to the third clamp body 6 through the fastener 2 7, and a wire hole 2 9 is formed between the third clamp body 6 and the corresponding first clamp body 1. When in use, if the return cable passes through the wire hole 2 9, the configuration of the first clamp body can be selected according to needs, such as a common flat sheet. Or as Figure 1 As shown, a groove 2 is formed on the bottom surface of the sheet body, and a groove 2 is formed in the middle position of the bottom surface of the sheet body so that the third clamp 6 is in an arch bridge shape as a whole, and fasteners 2 7 are arranged at both ends of the third clamp 6, and a wire hole 2 9 is formed between the groove 1 and the first top surface below. Of course, the third clamp can also be installed on the side wall of the first clamp body in the length direction, such as being installed on the side wall of the first clamp body at the upper right of the left fastener 1, according to the needs.

[0031] For fastener 2, if Figure 1 As shown, bolts are used as fasteners 2 7, the bolts pass through holes at both ends of the third clamp and are threadedly connected with threaded holes on the top surface of the first clamp 1 below, and the bolts are screwed down to allow the third clamp to cooperate with the first clamp to clamp the return cable passing through the wire hole 2. Of course, fastener 2 can also adopt a buckle, embedded column or other structure like fastener 1, which can be selected according to needs. In addition, multiple grooves 2 can also be formed on the bottom surface of the third clamp to clamp multiple return cables.

[0032] One method of use is to fix the second clamp on the cable bracket, so that the cable can be installed in one place of the groove at one time, and then the first clamp is installed, and the first clamp and the second clamp are fixed with fastener one to clamp the cable at one place of the wire hole, and then the third clamp is fixed with fastener two, and the third clamp cooperates with the first clamp to clamp the return cable, etc.

[0033] In this example, the orientations of the openings of the wire hole 1 8 and the wire hole 2 9 are consistent, which is consistent with the laying habits of cables, return cables, etc. Of course, the orientations of the wire hole 1 and the wire hole 2 can also be made to have a certain angle according to needs, which can be selected according to needs.

[0034] In addition, gaskets such as rubber gaskets can be fixed on the cavity walls of groove 1 and groove 2, and mounting holes can be formed on the second clamp located below, such as through holes formed longitudinally at both ends of the second clamp, and the second clamp 2 can be fixed to the cable bracket with bolts 5 and nuts.

[0035] In order to reduce weight, the first clamping body and the second clamping body outside the groove 1 can also be hollowed out, such as Figure 1 As shown, a hole 10 is hollowed out at the clamping body between the grooves.

[0036] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
