[0003] Therefore, the purpose of the utility model is to provide an anti-loosening isolation distribution box. Through the mutual cooperation of the set isolation distribution box assembly and the joint locking assembly, the outer shell can be locked twice when in use. Even if the secondary locking screws are loose, the limit joint outer frame still remains in a locked state, completely avoiding the problem of the outer shell detaching due to loose screws. After the secondary locking, the connected wires can also be pressed under force to avoid the wire connection from being subjected to pulling force, prevent the wire connection from being detached under force, improve the stability of the wire connection, and avoid the occurrence of safety hazards.

[0013] Wherein, the long sliding block and the long sliding groove are fitted with each other.

[0014] Compared with the prior art, the advantages of the utility model are:

[0015] 1. The utility model achieves secondary joint locking of the outer shell during use through the cooperation of the isolated distribution box assembly and the joint locking assembly. Even if the secondary locking screws are loose, the limit joint outer frame still remains locked, completely avoiding the problem of the outer shell detaching due to the loosening of the screws. After the secondary locking, the connected wires can also be pressed and tightened to avoid the wire connection from being pulled, preventing the wire connection from being detached due to force, thereby improving the stability of the wire connection and avoiding the occurrence of safety hazards.

At this time, the user uses a limiting joint outer frame to fit on the outer surface of the first semi-arc shell and the second semi-arc shell, and the round tube and the threaded tube are fitted. At this time, a threaded long rod is used to connect the threaded tube to each other, so that the round tube and the threaded tube can be locked. The limiting joint outer frame limits the first semi-arc shell and the second semi-arc shell to be combined together to avoid separation. With such a structural design, when the screws are loose, the first semi-arc shell and the second semi-arc shell are still combined. Separation, even if the long threaded rod is detached, the limit joint outer frame is still located on the top surface of the distribution box body and the outer shell due to gravity, and the limit joint outer frame always keeps the first semi-arc shell and the second semi-arc shell in a state of being locked together, and when the wire passes through the first semi-arc shell and the second semi-arc shell, the user rotates the two threaded columns respectively, and the two threaded columns are threaded progressively in the corresponding threaded holes, directly causing the two arc plates to clamp the wires from both sides, so that the wires are clamped and stressed. At this time, when the wires are pulled by the outside world, the arc plates are clamped and stressed, so that the connection between the wires and the distribution box body will not be pulled, thereby preventing the wires from detaching.

[0027] The utility model provides an anti-loosening isolation distribution box. Through the cooperation of the arranged isolation distribution box component and the joint locking component, the outer shell is locked twice when in use. Even if the screws of the secondary locking are loose, the limit joint outer frame still maintains a locked state, and the problem of the outer shell being separated due to the loosening of the screws is completely avoided. After the secondary locking, the connected wires can also be pressed under force to avoid the wire connection receiving pulling force, prevent the wire connection from being separated under force, improve the stability of the wire connection, and avoid the occurrence of safety hazards.

[0028] Example 1

[0029] Figure 1 , Figure 2 The figure shows the overall structure of an anti-loosening isolation distribution box of the utility model. Figure 1 , Figure 2 The main structure of this embodiment includes: an isolation distribution box assembly and a combined locking assembly.

[0030] The isolation distribution box assembly is used in conjunction with the joint locking assembly. Specifically, the isolation distribution box assembly includes a distribution box body 11, an outer shell 12 covering the outer surface of the distribution box body 11, a screw 13 passing through the distribution box body 11 and the outer shell 12, a first semi-arc shell 14 connected to the top of the outer shell 12, and a second semi-arc shell 15 connected to the top of the distribution box body 11;

[0031] During specific use, the first semi-arc shell 14 and the second semi-arc shell 15 are connected to form a cylindrical shape, the connecting wire passes through the first semi-arc shell 14 and the second semi-arc shell 15 and is connected to the distribution box body 11, and the combined locking assembly is installed and used based on the distribution box body 11, the outer shell 12, the first semi-arc shell 14 and the second semi-arc shell 15.

[0032] The combined locking assembly is used for secondary locking of the outer shell 12. Specifically, the combined locking assembly includes a position-limiting combined outer frame 21 arranged above the first semi-arc shell 14, a round tube 22 fixed on both sides of the outer portion of the position-limiting combined outer frame 21, a threaded long rod 23 arranged above the round tube 22, a threaded cylinder 24 fixed on the top of the outer shell 12, a threaded hole 25 opened on the surface of the position-limiting combined outer frame 21, a threaded column 26 penetrating the threaded hole 25, and an arc plate 27 arranged in the position-limiting combined outer frame 21;

[0033] During specific use, the outer shell 12 covers the surface of the distribution box body 11, and the screws 13 are used to lock the outer shell 12. At this time, the first semi-arc shell 14 and the second semi-arc shell 15 are connected to each other to form a cylinder. At this time, the user uses the limiting joint outer frame 21 to fit on the outer surface of the first semi-arc shell 14 and the second semi-arc shell 15, and the round tube 22 is fitted with the threaded tube 24. At this time, the threaded long rod 23 is used to connect the threaded tube 24 to each other, so that the round tube 22 and the threaded tube 24 can be locked. The limiting joint outer frame 21 limits the first semi-arc shell 14 and the second semi-arc shell 15 together to avoid separation. With such a structural design, when the screws 13 are loosened, the first semi-arc shell 14 and the second semi-arc shell 1 5 is still connected and not separated. Even if the threaded long rod 23 is separated, the limit joint outer frame 21 is still located on the top surface of the distribution box body 11 and the outer shell 12 due to gravity. The limit joint outer frame 21 always keeps the first semi-arc shell 14 and the second semi-arc shell 15 in a state of being locked together. When the wire passes through the first semi-arc shell 14 and the second semi-arc shell 15, the user rotates the two threaded columns 26 respectively. The two threaded columns 26 are threaded progressively in the corresponding threaded holes 25, and the two arc plates 27 are directly clamped from both sides of the wire. In this way, the wire is clamped and stressed. At this time, when the wire is pulled by the outside, the arc plate 27 is clamped and stressed. In this way, the connection between the wire and the distribution box body 11 will not be pulled, so as to prevent the wire from being separated.

[0034] Example 2

[0035] Please refer to Figure 3 , by providing the long slide slot 31 and the long slider 32, the round tube 22 can be replaced, so that it can be used for threaded tubes 24 of different diameters;

[0036] Specifically, it also includes a replacement component, which includes a long slide groove 31 opened on the surface of the limit joint outer frame 21 and a long slider 32 fixed on the outer side wall of the round tube 22;

[0037] The long slider 32 and the long slide slot 31 are fitted together;

[0038] During specific use, the long slider 32 slides in the long slide groove 31, so that the round tube 22 can be directly pulled out, which makes it convenient to replace the round tube 22. With such a replaceable structural design, when the threaded long rod 23 and the threaded tube 24 are locked, the top of the threaded long rod 23 is pressed against the top surface of the round tube 22 and the limiting joint outer frame 21, so that the limiting joint outer frame 21 can still be locked, without affecting the normal limiting use of the limiting joint outer frame 21.

[0039] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
