[0027] Refer to the attached Figure 1 The embodiment of the present application provides a cable clamp, including a base 1, on which an elastic clamping part 2 and a connecting part are arranged, and the elastic clamping part 2 and the connecting part cooperate to clamp and fix the cable. The connecting part is provided with a first locking part 3 and a second locking part 4, and the elastic clamping part 2 includes a bearing part 201, a first locking part 202 and a second locking part 203. The bearing part 201 is an arc-shaped structure and is integrally constructed on the surface of the base 1 for accommodating the cable, the first locking part 202 is buckled with the first locking part 3, and the second locking part 203 is buckled with the second locking part 4, and the first locking part 3 and the first locking part 202 are located inside the second locking part 4 and the second locking part 203. It is not difficult to understand that after the cable is placed inside the clamp, the first locking part 3 and the first locking part 202 are buckled to complete a single locking of the cable, and then the second locking part 4 and the second locking part 203 are buckled to form a double locking of the cable, thereby effectively reducing the risk of the clamp being disengaged.

[0028] Specifically:

[0029] like Figure 1 As shown, at least one group of elastic adjustment parts 5 is provided on the inner side of the elastic clamping part 2, a cavity 6 is reserved between the elastic adjustment part 5 and the elastic clamping part 2, and an adjustable clamping cavity 7 for clamping cables is formed between the inner sides of the elastic adjustment part 5. It is not difficult to understand that the clamping cavity 7 is formed by the elastic adjustment part 5, and the elastic adjustable performance of the elastic adjustment part 5 can be used to change the clamping diameter of the clamping cavity 7, so as to clamp cables of different cable diameters and improve the practicality of the cable clamp. In addition, since a cavity 6 is reserved between the elastic adjustment part 5 and the elastic clamping part 2, space can be provided for changing the clamping diameter of the clamping cavity 7, which facilitates the clamping of cables with large cable diameters.

[0030] In the above, the elastic adjustment plate can be an airbag structure, and the variability of the clamping diameter is achieved by utilizing the characteristics of the airbag that the volume becomes smaller when it is compressed and becomes larger when it is decompressed.

[0031] In an exemplary embodiment, Figure 1 As shown, the first locking portion 202 is integrally formed with the bearing portion 201, with the bearing portion 201 at the bottom and the first locking portion 202 at the top. A first entrance portion for the cable to enter the inner side of the elastic adjustment portion 5 is formed between the first locking portion 202 and the bearing portion 201, and a second entrance portion for the cable to be clamped into the clamping cavity 7 is also formed between the elastic adjustment portion 5. The first entrance portion and the second entrance portion are arranged on the same side, so as to facilitate the cable to be placed from the outside of the clamp into the clamping cavity 7. At the same time, in a preferred embodiment, as Figure 1 As shown, the elastic adjustment portion 5 is fixedly connected to the bearing portion 201, and an open groove portion 8 is formed between the two elastic adjustment portions 5. The open groove portion 8 is used to limit the positioning ribs for installing the cable, so that the open groove portion 8 is used to limit the cable to prevent the cable from rotating freely in the clamping cavity 7.

[0032] The above Figure 1 As shown, the outer wall of the first locking portion 202 is provided with a plurality of locking teeth 204 along one side of the first entrance portion toward the side of the bearing portion 201, and the first locking portion 3 is provided with a locking hook 301 on the side facing the first locking portion 202, and the locking hook 301 is engaged with the locking teeth 204 at different positions, thereby adjusting the clamping diameter of the clamping cavity 7 to clamp cables of different cable diameters. At the same time, based on the mutual buckling of the first locking portion 202 and the second locking portion 203, the first heavy locking of the cable placed in the clamping cavity 7 can be completed.

[0033] In a preferred embodiment, the side wall of the first locking part 202 is integrally formed with a power assisting plate 9, which provides a fulcrum for the user to press the first locking part 202 to engage with the first locking part 3, facilitates the engagement of the first locking part 202 with the second locking part 203 and saves effort for the user.

[0034] In another embodiment, the second locking part 4 includes a lock body 401, which is integrally formed on a side of the first locking part 3 away from the first locking part 202. The lock body 401 is provided with a lock cavity 402, and a side groove is provided on the side of the lock cavity 402 facing away from the first locking part 3. The second locking part 203 includes an elastic connecting plate 2030 and an elastic locking tongue. The elastic connecting plate 2030 is an L-shaped plate. The non-right-angle end of the elastic connecting plate 2030 is fixedly connected to the power-assisting plate 9, and the elastic connecting plate 2030 is fixed to form a spatially displaced arrangement with the lock body 401. The right-angle end of the elastic connecting plate 2030 is provided with a locking tongue, which is a pair of outward-bounced springs. The springs are connected to the elastic connecting plate 2030 at one end and are in a closed cone shape. The springs are in a right-angle plate shape at one end away from the elastic connecting plate 2030. It is conceivable that after the first locking portion 202 and the first locking portion 3 are buckled, the second locking portion 203 will rotate at a certain angle with the first locking portion 202. At this time, the right-angle end of the elastic connecting plate 2030 in the second locking portion 203 turns to face the lock body 401. Since the elastic connecting plate 2030 is misaligned with the lock body 401 and the elastic connecting plate 2030 is located at the rear side of the lock cavity 402, the elastic connecting plate 2030 needs to be bent forward a certain distance before the lock tongue can be inserted into the lock cavity 402. It can be seen that since the spring piece expands outwards, it forms a tight fit connection after being inserted into the lock cavity 402 to prevent disengagement. At the same time, since the elastic connecting plate 2030 is misaligned with the lock body 401, the bent elastic connecting plate 2030 will form an elastic force toward one side of the inside of the lock cavity 402, so that the elastic connecting plate 2030 has a tendency to move toward the inside of the lock cavity 402, thereby further preventing disengagement.

[0035] It can be seen that the cable clamp provided in the embodiment of the present application, by setting the first locking part 3 and the first locking part 202 to buckle together, uses the second locking part 4 and the second locking part 203 to form a secondary lock on the outside of the first locking part 3 and the first locking part 202, thereby significantly improving the anti-disengagement effect of the cable clamp.

[0036] In the above, see Figure 2 As shown, the base 1 includes a base body 101, and the first connection part 102 and the second connection part 103 are respectively arranged on both sides of the base body 101, and the first connection part 102 and the second connection part 103 are staggered in the height direction, and the first connection part 102 and the second connection part 103 are respectively provided with a first connection hole 104 and a second connection hole 1141, and the first connection hole 104 and the second connection hole 1141 are provided with a fixing member, so as to install and fix the fixture. Yes, the fixing member can be an expansion bolt.

[0037] In another exemplary embodiment, the base 1 can refer to Figure 3 and Figure 4The structure shown specifically includes a seat body 101 and a connecting piece 105. The connecting piece 105 is arranged parallel to the bottom of the seat body 101. A fixed connection part is integrally formed on one side of the connecting piece 105. The fixed connection part includes a fixing piece 106 and a biasing piece 107. One end of the biasing piece 107 is integrally connected to the fixing piece 106, and the other end thereof is deflected to the side away from the seat body 101 and integrally connected to the connecting piece 105. At the same time, a mounting part is also arranged on the fixing piece 106. The mounting part is provided with a fastening device for connecting to the mounting wall surface as required. The fastening device can be a nail 108 as required. On the one hand, the above-mentioned nail 108 is stimulated by a special nail 108 device, which is easy to operate and can effectively improve work efficiency; on the other hand, it can be deeply and firmly driven into the cable trough, thereby realizing stable installation of the fixture.

[0038] In the above embodiment, the connecting piece 105 is fixedly connected to the base body 101 by a fastening connection device, wherein the fastening connection device includes a first connection component and a second connection component, the first connection component includes two groups of four limit blocks 109, each limit block 109 is integrally formed at the bottom of the base body 101 and protrudes toward the middle side, and a card slot is formed at the bottom of the part of the limit block 109 protruding toward the middle, and the connecting piece 105 is provided with two groups of avoidance openings 110, and the connecting piece 105 is inserted into the inner side of the limit block 109 through the avoidance openings 110, and the connecting piece 105 between the avoidance openings 110 is inserted into the card slot of the part of the bottom of the limit block 109 protruding toward the middle, so that the connecting piece 105 and the limit block 109 are fitted and limited, and then the stable connection between the connecting piece 105 and the base body 101 is achieved through the cooperation between the limit block 109 and the avoidance openings 110, and its structure is simple and easy to operate.

[0039] At the same time, the first connecting component also includes a sliding slot 111 and a sliding limit block 112. The sliding slot 111 is arranged on the connecting piece 105. The sliding limit block 112 is integrally connected to the seat body 101, and its free end is slidably inserted into the sliding slot 111. At the same time, auxiliary limit blocks 113 protruding out of the sliding slot 111 are arranged on both sides of the sliding limit block 112. The auxiliary limit blocks 113 are fitted with the connecting pieces 105 on both sides of the sliding slot 111 to achieve limiting. At the same time, the side of the sliding limit block 112 is fitted with the inner wall of the sliding slot 111 to achieve limiting. The sliding slot 111 is also provided with a connecting hole 114 for disassembling and assembling the auxiliary limit block 113. The connecting hole 114 is connected to the sliding slot 111 to form a T-shaped structure.

[0040] In addition, the second connecting component includes an elastic lock buckle 115 and a lock groove 116. The lock groove 116 is a square hole set on the connecting plate 105; the elastic lock buckle 115 includes a locking hook, and the locking hook has a push surface, which abuts against the top inner wall of the lock groove 116 to achieve locking limit.
