DETAILED DESCRIPTION

[0028] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0029] refer to Figures 1 to 4 A transformer control box that is easy to disassemble comprises a box body 1 and a box cover 2, wherein the box cover 2 is detachably connected to the box body 1, and the box body 1 and the box cover 2 form a box body with a hollow interior;

[0030] The box body 1 is provided with a plurality of groups of card blocks 3, and the surface of the box cover 2 facing the box body 1 is connected with buckles 4 corresponding to the plurality of groups of card blocks 3, and the buckles 4 and the card blocks 3 are both stepped, and the buckles 4 cooperate with the card blocks 3 to connect the box cover 2 and the box body 1;

[0031] The surface of the box body 1 facing the box cover 2 is provided with a plurality of limiting grooves 5, and the surface of the box cover 2 facing the box body 1 is connected with limiting strips 6 corresponding to the plurality of limiting strips. The limiting grooves 5 cooperate with the limiting strips 6 to limit the installation position of the box cover 2.

[0032] In actual use, the number and position of the limiting grooves 5 can be set according to actual conditions. In this embodiment, the limiting grooves 5 are located at the two corners on the upper side of the box body 1 and at the edge of the box body 1 close to the lower side. In another embodiment, the limiting grooves 5 can also be set at the four corners.

[0033] It should be noted that, in the present embodiment, the step-shaped buckle 4 and the block 3 both include a base portion and a clamping portion, the base portion is an arc-shaped plate, the clamping portion is a convex strip raised on the arc-shaped plate, the convex strip is trapezoidal, and the convex strips are provided in multiple groups and arranged in a straight line. When the buckle 4 and the block 3 are clamped together, the convex strips on the buckle 4 and the convex strips on the block 3 are arranged alternately.

[0034] It should be further explained that the number of blocks 3 can be set to two groups, three groups, four groups, etc., but it is not recommended to set too many groups. Too many settings will affect the internal space of the box 1. When the buckles 4 are set to two groups, the two groups of buckles 4 can be symmetrically set. When the number of buckles 4 is set to three groups or more, it is necessary to ensure that there is a sufficient distance between every two groups of buckles 4 so that the buckles 4 can be rotated out of the block 3.

[0035] Furthermore, the surface of the box cover 2 is rotatably connected to a rotating plate 7, the buckles 4 are connected to the surface of the rotating plate 7, at least two groups of the buckles 4 are provided, the surface of the rotating plate 7 is rotatably connected to a connecting piece, the connecting piece extends to the outside of the box body, and the connecting piece drives the rotating plate 7 to rotate.

[0036] It should be noted that the present invention is applicable to a small transformer control box.

[0037] Furthermore, the rotating plate 7 is connected to the surface of the box cover 2 via a rotating shaft.

[0038] Furthermore, a slide groove 9 is provided on the surface of the box body 1 on one side close to the box cover 2 , and the connecting piece extends into the slide groove 9 .

[0039] Furthermore, the connecting member is a telescopic rod 10. When the telescopic rod 10 is pushed, the telescopic rod 10 contracts to drive the rotating plate 7 to rotate.

[0040] refer to Figures 3 to 6 The telescopic rod 10 includes a fixed rod 101, a movable rod 102 and a compression spring 103. The fixed rod 101 is sleeved on the surface of the movable rod 102. One end of the compression spring 103 is connected to the inner wall of the fixed rod away from the movable rod 102, and the other end is connected to an end of the movable rod 102 located inside the fixed rod 101. The end of the movable rod 102 away from the fixed rod 101 is rotatably connected to the rotating plate 7, and the end of the fixed rod 101 away from the movable rod 102 passes through the slide groove 9.

[0041] Furthermore, a slide rail 8 is connected to the surface of the box cover 2 , a slider 11 is slidably connected to the inner wall of the slide rail 8 , and the slider 11 is connected to the fixing rod 101 .

[0042] It should be noted that the slide rail 8 cooperates with the slider 11 to limit the upward and downward movement of the fixing rod 101 .

[0043] In actual use, when the box cover 2 needs to be removed from the box body 1, the fixing rod 101 is pushed to extend out of one end of the slide slot 9 to drive the buckle 4 to rotate. When the buckle 4 is completely rotated out of the block 3, the box cover 2 can be removed from the box body 1.

[0044] Furthermore, a connecting plate 12 is connected to the surface of the buckle 4, and a resisting plate 13 is connected to the surface of the box cover 2. The resisting plate 13 is in contact with the connecting plate 12, and the contact surface is an inclined surface.

[0045] Furthermore, a fixing plate 14 is connected to the surface of the box cover 2 , a tension spring 15 is connected to the surface of the fixing plate 14 , and one end of the tension spring 15 is connected to the surface of the abutment plate 13 .

[0046] It should be noted that the connecting plate 12 is connected to one end of the buckle 4 close to the block 3. When the buckle 4 gradually rotates out of the block 3, the connecting plate 12 gradually contacts the push plate 13. Due to the action of the tension spring 15, the push plate 13 has a certain supporting force on the connecting plate 12, so it can drive the end of the buckle 4 close to the block 3 to move in the direction away from the axis of the rotating shaft, so that the buckle 4 and the block 3 will not be clamped too tightly, thereby facilitating the buckle 4 to be rotated out of the block 3.

[0047] refer to Figure 7 The surface of the abutment plate 13 away from the tension spring 15 and the inclined surface are both provided with ball grooves, and a ball 16 is rollingly connected inside the ball groove, and the ball 16 is in contact with the connecting plate 12.

[0048] It should be noted that a plurality of ball grooves are provided on the surface of the abutment plate 13 away from the tension spring 15 and are arranged in an array along the surface of the abutment plate 13 . The balls 16 are arranged to reduce friction.

[0049] refer to Figure 8 A baffle 17 is connected to the surface of the fixed rod 101 away from one end of the movable rod 102, and the baffle 17 moves along the surface of the middle frame to block the sliding groove 9.

[0050] It should be noted that when the box cover 2 is installed on the box body 1, the baffle 17 completely covers the slide groove 9. There is a protrusion on the baffle 17 to facilitate the movement of the fixing rod 101. When the protrusion is pushed, the baffle 17 that moves with it can also completely cover the slide groove 9, effectively preventing dust from falling into the control box from the slide groove 9.

[0051] In this solution, the box cover 2 can be directly removed from the box body 1 by pulling, or by pushing the telescopic rod 10 to drive the buckle 4 to rotate, so that the box cover 2 can be removed from the box body 1. However, preferably, the display assembly needs to be removed by rotating the buckle 4 first, because pulling may break the convex strip.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
