[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figure 1-5 The embodiment of the utility model provides a technical solution: a distribution box with a box door locking mechanism, including a box body 1 and a box door 2 rotatably arranged on the box body 1, a plurality of locking blocks 3 are slidably arranged on the box body 1, the locking blocks 3 slide horizontally along the box body 1, and a sliding rod 4 is slidably arranged in the box body 1, and the sliding rod 4 slides horizontally along the box body 1, and each locking block 3 is connected to the sliding rod 4 by a connecting rod 5, so that the locking block 3 and the sliding rod 4 slide synchronously, and a first elastic member 6 is sleeved on the outer side of the connecting rod 5, and a plurality of locking grooves 7 adapted to each locking block 3 are opened on the box door 2, one end of the first elastic member 6 is fixed on the locking block 3, and the other end is fixed on the box body 1, and its elastic force makes the locking block 3 press against the locking groove 7; it also includes an unlocking component, which is arranged in the box body 1, and is used to unlock each locking block 3 at the same time, so as to realize the unlocking of the box door 2 and facilitate the opening of the box door 2.

[0023] The utility model can lock and fix the different positions of the box door 2 by cooperating with the multiple locking blocks 3 and the locking grooves 7, thereby improving the locking effect. At the same time, the sliding rod 4, the connecting rod 5 and the unlocking assembly can be used to unlock the locking blocks 3 at the same time to facilitate the opening of the box door 2, thereby solving the problem in the prior art that the distribution box door has only one locking tongue, the upper and lower positions of the door are prone to warping, and the locking effect is affected.

[0024] In another embodiment provided by the utility model, the first elastic member 6 is a compression spring, and its elastic force is used for sliding and restoring when the squeezing force of the locking block 3 disappears. That is, after the door 2 is closed, the elastic restoring force of the first elastic member 6 drives the locking block 3 to slide in the direction of the door 2, insert into the locking groove 7, and lock the door 2.

[0025] In another embodiment provided by the utility model, a rounded corner is provided on the locking block 3 so that when the box door 2 is closed, the locking block 3 is squeezed to slide into the box body 1, that is, the locking block 3 of this design does not affect the closing of the box door 2, and the box door 2 can be locked by the locking block 3 after the box door 2 is closed.

[0026] In another embodiment of the present invention, a slide groove 8 adapted to the sliding rod 4 is provided in the box body 1 to adapt to the movement stroke of the sliding rod 4 .

[0027] In another embodiment provided by the utility model, the unlocking component includes a rotating shaft 9 rotatably arranged in the box body 1, and a cam 10 is sleeved on the rotating shaft 9. The cam 10 is fixed on the rotating shaft 9 and moves synchronously with the rotating shaft 9. The cam 10 abuts against the sliding rod 4, so that when the rotating shaft 9 rotates, the cam 10 rotates synchronously, squeezing the sliding rod 4 to slide, so as to unlock the locking block 3, that is, when the rotating shaft 9 rotates, the cam 10 is driven to rotate, and the sliding rod 4 is squeezed during the rotation of the cam 10, so that the sliding rod 4 slides, and drives the locking block 3 to slide synchronously, so that the locking block 3 slides out of the locking groove 7, and each locking block 3 is unlocked at the same time.

[0028] In another embodiment provided by the present invention, the rotating shaft 9 is arranged through the box body 1, and a rotating knob 11 is slidably arranged at one end of the rotating shaft 9, and the rotating knob 11 slides horizontally along the rotating shaft 9 (refer to Figure 4 ), a second elastic member 12 is arranged between the rotating knob 11 and the rotating shaft 9, and the second elastic member 12 is a compression spring, and its elastic force is used to drive the rotating knob 11 to slide and reset in the direction of the rotating shaft 9 when the external force of the rotating knob 11 disappears. A limiting rod 13 is arranged on the second elastic member 12, and the limiting rod 13 slides synchronously with the rotating knob 11. In the process of sliding and resetting the rotating knob 11, the limiting rod 13 is inserted into the limiting groove 14 to limit and fix the rotating knob 11. A limiting groove 14 adapted to the limiting rod 13 is provided on the box body 1. There are two limiting grooves 14, and the two limiting grooves 14 are arranged at 90 degrees, that is, when the limiting rod 13 is located in one of the limiting grooves 14, the locking block 3 can be kept in a locked state, and when the limiting rod 13 is located in the other limiting groove 14, the locking block 3 is kept in an unlocked state. This design can realize the limiting fixation of the rotating knob 11, so that the locking block 3 remains in a locked or unlocked state.

[0029] In actual use, during the closing process of the box door 2, the fillets on the locking blocks 3 are squeezed so that the locking blocks 3 slide and shrink toward the inside of the box body 1. During the sliding process of the locking blocks 3, the connecting rod 5 drives the sliding rod 4 to move synchronously. After the box door 2 is closed, the locking groove 7 is aligned with the position of the locking block 3. At this time, the elastic restoring force of the first elastic member 6 drives the locking block 3 to slide and reset, and insert it into the locking groove 7 to achieve the locking of the box door 2. When unlocking is required, first pull the rotary knob 11, refer to Figure 4 , pull the rotating knob 11 to the left, so that the rotating knob 11 slides away from the rotating shaft 9, and at the same time, drives the limiting rod 13 to slide out of the limiting groove 14, and then rotates the rotating knob 11, so that the rotating shaft 9 drives the cam 10 to rotate 90 degrees synchronously, referring to Figure 2The cam 10 rotates 90 degrees in the direction of the sliding rod 4. During the rotation of the cam 10, the sliding rod 4 is squeezed, so that the sliding rod 4 slides along the sliding groove 8, and the locking block 3 is driven to slide synchronously through the connecting rod 5, so that the locking block 3 slides out of the locking groove 7, and the locking block 3 is in an unlocked state. At this time, the limit rod 13 is rotated and aligned with another limit groove 14, and the rotating knob 11 is slowly released. The elastic restoring force of the second elastic member 12 drives the rotating knob 11 to slide in the direction of the rotating shaft 9, that is, drives the limit rod 13 to be inserted into the limit groove 14, so as to realize the limit fixation of the rotating knob 11, and the box door 2 can be opened by rotating.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
