Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a low-voltage distribution box with good sealing performance. Background Art

[0002] The reference patent name is: A low-voltage distribution box with good sealing performance (patent publication number: CN210404484U, patent publication date: 2020-04-24), including a distribution box body, which is composed of a box body and a box door hinged on the left side of the front of the box body. An annular plate is fixedly installed on the front of the inner cavity of the box body, and a sealing mechanism is arranged on the front of the annular plate. The sealing mechanism is composed of four reset springs, an annular clamp and a rubber ring arranged on the back of the box door. The annular plate is connected to the annular plate through four reset springs. Heat sinks are fixedly installed on both sides of the box body, and heat dissipation holes are opened on the outside of the inner cavity of the heat sink box. A fan is fixedly installed in the middle of the outer side of the inner cavity of the heat sink box. This kind of low-voltage distribution box with good sealing performance, through the sealing mechanism, when the rubber ring shrinks due to cold, the reset spring can push the annular clamp to squeeze the rubber ring, causing it to be squeezed and expanded, so that the outside of the rubber ring is still in contact with the inner wall of the box body, so that there will be no gap between the rubber ring and the box body, and the sealing performance is strong.

[0003] However, when implementing the above technical scheme, there are the following problems: the above scheme can achieve that the sealing ring inside the distribution box is kept in contact with the inner wall of the box through structural support when the sealing ring shrinks due to the cold, but the sealing ring is easily separated from the inside of the box after the distribution box is opened by structural support. When the sealing ring shrinks due to the cold, its external circumference and width will be reduced to a certain extent. At this time, the fixed position of the sealing ring and the box will change, and the two are not completely fixed at this time. Under the action of external force, the sealing ring moves outward as a whole, which may cause the sealing ring to detach from the inside of the surface groove of the distribution box. When the distribution box door is opened, the sealing ring will fall off, and a new sealing ring needs to be replaced for subsequent use. For this reason, the utility model provides a low-voltage distribution box with good sealing performance. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a low-voltage distribution box with good sealing performance, which solves the problem that the sealing ring at the door of the low-voltage distribution box shrinks and moves outward through the structure to ensure that it contacts the box body and then the sealing ring is easily separated from the box body when the distribution box is opened.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions: a low-voltage distribution box with good sealing performance, including a distribution box body, a sealing door is rotatably provided on the surface of the distribution box body, a sealing mechanism is provided between the distribution box body and the sealing door to achieve a tight fit, and the sealing mechanism includes:

[0006] A sealing component is arranged on the surface of the distribution box body to achieve structural fitting, including a sealing ring, a fixing groove is opened on the surface of the sealing ring, a fixing block and a clamping block are fixed inside the distribution box body, a supporting component is arranged between the clamping block and the sealing ring to achieve structural fixation, and an elastic component is arranged on the surface of the clamping block to maintain the structural position;

[0007] The support assembly is arranged between the sealing ring and the distribution box body to achieve structural fixation, including a fixed rod that slides inside the card block, a sliding assembly is arranged between the fixed rod and the card block to achieve sliding restriction, a limiting assembly is arranged between the fixed rod and the distribution box body to achieve position limitation, and a synchronization assembly is arranged between the fixed rods to achieve synchronous movement.

[0008] Preferably, the elastic assembly comprises an elastic block which slides inside the locking block, and an elastic spring is fixedly connected between the elastic block and the locking block.

[0009] Preferably, the sliding assembly comprises a sliding shaft fixed on the surface of the fixed rod, and a sliding groove is provided inside the clamping block.

[0010] Preferably, the limiting assembly includes a limiting column that slides inside the distribution box body, and a limiting groove is provided on the surface of the fixing rod.

[0011] Preferably, the synchronization component comprises a synchronization column rotatably connected to the inside of the card block, a driving groove is provided on the surface of the synchronization column, and a driving shaft is fixedly connected to the inside of the fixing rod.

[0012] Preferably, the interior of the agglomerating block is rotatably connected to a transfer cone wheel, and the surface of the synchronous column is fixedly connected to a fixed cone wheel.

[0013] Beneficial Effects

[0014] The utility model provides a low-voltage distribution box with good sealing performance. Compared with the prior art, it has the following beneficial effects:

[0015] (1) The low-voltage distribution box with good sealing performance realizes simple clamping and position fixing by using fixing grooves, fixing blocks and clamping blocks between the surface of the distribution box body and the sealing ring, and a deeper rectangular groove is set at the position of the fixing groove. The fixing rod is contacted with the inner surface of the fixing groove by sliding inside the clamping block, so that the position of the sealing ring inside the distribution box body can be further determined. The position of the sealing ring inside the distribution box body is further limited by the contact between the clamping block, the fixing rod and the fixing block and the surfaces of the fixing grooves at different positions and depths. When the sealing ring shrinks, it is difficult for it to directly separate from the inner surface of the distribution box body.

[0016] (2) The low-voltage distribution box with good sealing performance is provided with a rotatable synchronous column inside the locking block. The sliding of the driving shaft and the driving groove between the synchronous column and the fixed rod drives the synchronous column to rotate by linear sliding. The synchronous columns at different positions inside the locking block are rotated simultaneously by a fixed cone wheel fixed at one end and a rotating transfer cone wheel. Therefore, the movement of the fixed block on one side can cause the fixed blocks on the four sides to move synchronously, thereby achieving further locking of the locking block and the sealing ring, and making the operation easier.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 , the utility model provides two technical solutions:

[0025] Embodiment 1

[0026] A low-voltage distribution box with good sealing performance comprises a distribution box body 1, a sealing door 2 is rotatably provided on the surface of the distribution box body 1, a lock structure is provided between the distribution box body 1 and the sealing door 2 to fix the position when closed, a sealing mechanism 3 is provided between the distribution box body 1 and the sealing door 2 to achieve tight fitting, and the sealing mechanism 3 comprises:

[0027] A sealing component is arranged on the surface of the distribution box body 1 to achieve structural fitting, including a sealing ring 31, a fixing groove 32 is opened on the surface of the sealing ring 31, and a fixing block 33 and a clamping block 34 are fixed inside the distribution box body 1. When the sealing ring 31 is placed inside the distribution box body 1, the surfaces of the fixing block 33 and the clamping block 34 will contact the inner surface of the fixing groove 32, the fixing block 33 is located on the upper side, and the clamping block 34 is located on the lower side of the sealing ring 31. A supporting component is arranged between the clamping block 34 and the sealing ring 31 to achieve structural fixation, and an elastic component 4 is arranged on the surface of the clamping block 34 to maintain the structural position;

[0028] A support component is arranged between the sealing ring 31 and the distribution box body 1 to achieve structural fixation, including a fixed rod 35 that slides inside the card block 34, a sliding component 5 is arranged between the fixed rod 35 and the card block 34 to achieve sliding restriction, and a limiting component 6 is arranged between the fixed rod 35 and the distribution box body 1 to achieve position limitation. There is a deeper rectangular groove in the fixed groove 32 opened on the surface of the sealing ring 31, and the fixed rod 35 can be inserted into the inside of the rectangular groove. A synchronization component 7 is arranged between the fixed rods 35 to achieve synchronous movement;

[0029] A simple fastening and position fixation are achieved between the surface of the distribution box body 1 and the sealing ring 31 through the fixing groove 32, the fixing block 33 and the locking block 34, and a deeper rectangular groove is set at the position of the fixing groove 32. The fixing rod 35 slides inside the locking block 34 to achieve contact with the inner surface of the fixing groove 32, so that the position of the sealing ring 31 inside the distribution box body 1 can be further determined. The contact between the locking block 34, the fixing rod 35 and the fixing block 33 and the surface of the fixing groove 32 at different positions and depths can further limit the position of the sealing ring 31 inside the distribution box body 1. When the sealing ring 31 shrinks, it is difficult for it to directly detach from the inner surface of the distribution box body 1.

[0030] Embodiment 2

[0031] The main difference from the first embodiment is:

[0032] A low-voltage distribution box with good sealing performance, wherein the elastic component 4 includes an elastic block 41 that slides inside the card block 34, and an elastic spring 42 is fixedly connected between the elastic block 41 and the card block 34. The sliding component 5 includes a sliding shaft 51 fixed on the surface of the fixed rod 35, and a sliding groove 52 is provided inside the card block 34. The surface of the sliding shaft 51 is slidably connected to the inner surface of the sliding groove 52. The limiting component 6 includes a limiting column 61 that slides inside the distribution box body 1, and a limiting groove 62 is provided on the surface of the fixed rod 35. The surface of the limiting column 61 can contact the inner surface of the limiting groove 62. The synchronization component 7 includes a synchronization column 71 that is rotatably connected to the inside of the card block 34, and a driving groove 72 is provided on the surface of the synchronization column 71. A driving shaft 73 is fixedly connected to the inside of the fixed rod 35, and the surface of the driving shaft 73 is in contact with the driving groove 72. The inner surface of the locking rod 7 is slidably connected, and the driving groove 72 surrounds the surface of the synchronous column 71. The internal rotation of the locking block 34 is connected to the transfer cone wheel 74. The surface of the locking rod 71 is fixedly connected to the fixed cone wheel 75. The surface of the transfer cone wheel 74 meshes with the surface of the fixed cone wheel 75. The transfer cone wheels 74 mesh with each other. A rotatable synchronous column 71 is provided inside the locking block 34. The sliding of the synchronous column 71 and the fixed rod 35 causes the linear sliding to drive the synchronous column 71 to rotate. The synchronous columns 71 at different positions inside the locking block 34 can rotate simultaneously through the fixed cone wheel 75 fixed at one end and the rotating transfer cone wheel 74. Therefore, the movement of the fixed block 33 on one side can cause the fixed blocks 33 on the four sides to move synchronously, thereby further locking the locking block 34 and the sealing ring 31, making the operation easier.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] During operation, when the sealing ring 31 is installed inside the distribution box body 1, the positions of the fixing groove 32 and the fixing rod 35 must first be aligned to ensure that the deeper rectangular portion of the fixing groove 32 is at the center of the four sides. Then, the sealing ring 31 is pressed into the inside of the distribution box body 1 by utilizing its elasticity, so that the surfaces of the card block 34 and the fixing block 33 are in contact with the inner surface of the fixing groove 32. At the same time, the inner surface of the sealing ring 31 squeezes the surface of the elastic block 41, and then presses the fixing rod 35 above. The sliding of the fixing rod 35 drives the shaft 73 and the driving groove 72 to drive the synchronous column 71 to rotate, and then through The cone wheel drives the synchronization column 71 on the other side to rotate, causing the fixing rod 35 on the other side to slide outward. When the fixing rod 35 slides to the upper end, it presses the limit column 61 downward, causing one end of the limit column 61 to be inserted into the inside of the limit groove 62, fixing the position of the upper fixing rod 35, and realizing the position fixation of the sealing ring 31. When the sealing ring 31 shrinks due to cold, the fixing rod 35 and the card block 34 will limit the change of its diameter. At the same time, the elastic block 41 will push the sealing ring 31 to ensure that the surface of the sealing ring 31 can contact the surface of the sealing door 2, thereby ensuring the overall sealing effect of the distribution box when the sealing door 2 is closed.
