DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0030] Embodiment: please refer to Figures 1-9 The utility model provides a technical scheme: a switchgear rear door side-mounted hinge structure, including cabinet frame 1 and rear door 2, rear door 2 is fixed on cabinet frame 1 through hinge assembly 4, and the side of rear door 2 away from hinge assembly 4 is provided with locking assembly 3, wherein locking assembly 3 is used for locking rear door 2 on cabinet frame 1, such as lock body.

[0031] Please refer to Figure 1 And Figure 2The hinge assembly 4 is uniformly arranged on the side of the back door 2 from top to bottom, and adjacent hinge assemblies 4 are arranged at intervals. The uniform arrangement of the hinge assembly 4 can guarantee the stress of the connection between the back door 2 and the cabinet frame 1, thereby improving the connection stability of the back door 2 and the cabinet frame 1.

[0032] Please refer to Figure 2 and Figure 3 The hinge assembly 4 comprises a hinge plate 41, a strip block 42, a pin shaft 43 and a limiting plate 44. The hinge plate 41 is provided with a clamping buckle 411, and the pin shaft 43 is movably inserted into the clamping buckle 411.

[0033] Further, the strip block 42 is provided with an insertion socket 421 on one side corresponding to the clamping buckle 411. The insertion socket 421 is provided with limiting holes 423 on the upper and lower sides, and the limiting holes 423 are longitudinally inserted with insertion holes 422 in the middle. The pin shaft 43 is movably inserted into the insertion holes 422. The insertion holes 422, the limiting holes 423 and the insertion socket 421 are directly arranged on the strip block 42. The limiting plate 44 can facilitate the fixation of the hinge assembly 4 on the back door 2.

[0034] Further, the pin shaft 43 is arranged between adjacent limiting rods 441, and the pin shaft 43 and the limiting rod 441 are in contact. The clamping buckle 411 passes through the insertion socket 421, and the center holes of the clamping buckle 411 and the insertion holes 422 correspond in position. The pin shaft 43 can facilitate the swinging of the back door 2 around a certain position of the cabinet frame 1 by a certain angle, thereby facilitating the opening of the back door 2.

[0035] Please refer to Figure 3 , Figure 6 and Figure 7 The limiting plate 44 is provided with limiting rods 441 on the upper and lower sides corresponding to the cabinet frame 1. The back door 2 is provided with through holes for the insertion of the limiting rods 441, and the number of through holes corresponds to the number of limiting rods 441. The limiting rods 441 are movably inserted into the limiting holes 423, and the center lines of the limiting rods 441 and the pin shaft 43 are perpendicular to each other. The through holes arranged on the back door 2 can facilitate the connection of the hinge assembly 4 and the back door 2.

[0036] Further, the outer end of the limiting rod 441 is connected with a clamping sleeve 442 through threads, and the outer diameter of the outer end of the clamping sleeve 442 is larger than the outer diameter of the limiting rod 441. A flexible plug 443 is inserted into the clamping sleeve 442. The clamping sleeve 442 and the limiting rod 441 are collinear, and the clamping sleeve 442 and the hinge plate 41 are in movable contact. The clamping sleeve 442 and the limiting rod 441 are connected through threads, which can facilitate the replacement and installation of the flexible plug 443. The flexible plug 443 is arranged at the end of the limiting rod 441, so that when the back door 2 shakes left and right, the elastic effect of the flexible plug 443 can reduce the anti-shock effect of the back door 2.

[0037] It is worth noting that, such as Figure 9 As shown, the flexible plug 443 is made of rubber, and the end of the flexible plug 443 away from the snap-fit ​​sleeve 442 has a conical end. The flexible plug 443 is configured such that its outer diameter is larger than its inner diameter. Initially, it is connected via... Figure 8 As shown, the engagement of the flexible plug 443 and the snap-fit ​​sleeve 442 prevents the flexible plug 443 from detaching from the snap-fit ​​sleeve 442. When the rear door 2 wobbles left and right, the larger diameter side of the flexible plug 443 has difficulty entering the snap-fit ​​sleeve 442. Thus, the flexibility of the flexible plug 443 can alleviate the left and right vibration of the rear door 2 and prevent the rear door 2 from contacting the cabinet frame 1. The up and down wobbling of the rear door 2 can be further restricted by the insertion slot 421 and the limiting rod 441.

[0038] Working principle: In this type of switch cabinet rear door side-mounted hinge structure, during the connection operation, the hinge plate 41 is inserted into the insertion slot 421 on the strip block 42, so that the inner diameter of the hinge plate 41 and the upper and lower positions of the insertion hole 422 correspond. The strip block 42 is then attached to the corresponding inner side of the rear door 2. The limiting plate 44 is inserted into the rear door 2 from the outside to the inside, and the limiting rod 441 on the limiting plate 44 is engaged with the corresponding positions on the rear door 2 and the strip block 42, thereby connecting and fixing the hinge assembly 4 to the rear door 2.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
