The beneficial effects of the utility model are that, the utility model discloses simple structure is articulated through the one end with casing 1 and door closure 2, then sets up buckle 21 at the other end of door closure 2, sets up retaining member 4 simultaneously on casing 1, through retaining member 4 and buckle 21's block effect, has realized opening fast and closing of door closure 2 and casing 1, need use connecting pieces such as screw simultaneously, and on the one hand, on the other hand has avoided the condition of connecting piece loss to take place.

According to the utility model discloses an embodiment is provided with hinge 3 between the one end of door closure 2 and the casing 1, and the one end of hinge 3 sets firmly on casing 1, the other end of hinge 3 and the one end rigid coupling of door closure 2. Preferably, the number of hinges 3 is two, the axes of rotation of the two hinges 3 being collinear. Hinge 3 can realize that the rotation between door closure 2 and the casing 1 is connected, utilizes two coaxial rotations of hinge 3 to accomplish simultaneously and articulates, has promoted the stability when door closure 2 is rotatory.

Wherein, retaining member 4 includes: two locking units and a cross beam 44, wherein the two locking units are arranged on the shell 1 and are symmetrical; the beam 44 is arranged on the housing 1, the beam 44 is located at one side of the opening, one end of the beam 44 is connected with one locking unit, the other end of the beam 44 is connected with the other locking unit, and the locking unit can drive the beam 44 to move towards the opening. That is, the two locking units are respectively installed at both ends of the cross member 44, ensuring the stability of the cross member 44.

On this basis, the locking unit includes: the mounting seat 41, the guide rod 42 and the spring 43, wherein the mounting seat 41 is fixedly arranged on the shell 1; the guide rod 42 is installed on the installation seat 41; the spring 43 is sleeved on the guide rod 42, one end of the spring 43 abuts against the mounting seat 41, the other end of the spring 43 abuts against the cross beam 44, and the spring 43 pushes the cross beam 44 to move towards the direction away from the opening. Preferably, the mounting seat 41 is a U-shaped member, one end of the guide rod 42 is clamped at one end of the mounting seat 41 through a retaining ring, the other end of the guide rod 42 is clamped at the other end of the mounting seat 41 through another retaining ring, and the spring 43 and the cross beam 44 are both sleeved at the middle part of the guide rod 42.

In other words, the mounting seat 41 is a U-shaped structure, the mounting seat 41 has two mounting plates which are oppositely arranged, one end of the guide rod 42 passes through one mounting plate, the other end of the guide rod 42 passes through the other mounting plate, the two ends of the guide rod 42 are limited by the retainer rings, the guide rod 42 is prevented from being separated from the mounting seat 41, the spring 43 keeps a certain compression state, and thus the cross beam 44 is under the elastic action of the spring 43 and keeps a state of being abutted to the buckle 21.

More preferably, the number of the buckles 21 is two, and two bayonets 441 are correspondingly formed on the cross beam 44. Carry out the block from two points, cooperate the articulated of two hinges 3, it is spacing that there are four points on the door closure 2, guaranteed the fixed stability of door closure 2.

It is further preferred that the catch 21 has a projection on the side facing the cross beam 44, which is caught in the catch 441.

Wherein, the side of the protrusion facing the bayonet 441 is formed as a first guiding surface 211, and the cross beam 44 has a second guiding surface 442 matching with the first guiding surface 211. Further, the first guide surface 211 and the second guide surface 442 are arc surfaces or inclined surfaces. Under the cooperation of the second guide surface 442 of the first guide surface 211, the protrusion on the side surface of the buckle 21 can be easily snapped into the bayonet 441, so as to lock the door cover 2.

During operation, the door cover 2 is covered on the housing 1 and pressed downwards, and the buckle 21 enters the bayonet 411 under the matching of the second guide surface 442 of the first guide surface 211, so that the door cover 2 is locked; when the door needs to be opened, the cross beam 44 is pressed to enable the cross beam 44 to be away from the buckle 21, the door cover 2 is not clamped, and the door cover 2 is rotated again to be opened.
