Description

Technical Field

[0001] The utility model relates to the technical field of charging and swapping cabinets, and particularly relates to a charging and swapping cabinet door with good sealing performance. Background Art

[0002] In order to extend the driving range of electric bicycles, various charging piles, swapping cabinets and charging cabinets have emerged on the market at present. The charging piles and charging cabinets have the same principle, that is, users need to carry chargers by themselves; the swapping cabinet directly replaces the dead battery in the electric bicycle with the charged battery in the swapping cabinet, and the swapping cabinet will charge the dead battery.

[0003] Multiple cabinets for placing batteries are installed on the charging and swapping cabinet, and a cabinet door is installed on each cabinet. Batteries are flammable materials, so water pipes are configured on each cabinet of the charging and swapping cabinet; when a fire breaks out in a certain cabinet, the water pipe in the corresponding cabinet will spray water, so as to submerge the batteries in the cabinet to achieve fire extinguishing. Therefore, the sealing performance of the cabinet door has become an important factor in whether the fire fighting water can be retained in the cabinet to submerge the batteries for fire extinguishing.

[0004] Most of the cabinet doors of the existing charging and swapping cabinets are pasted with a sealing rubber strip around the matching position of the inner wall of the cabinet door and the door frame, and the sealing of the cabinet door is realized by pressing the sealing rubber strip against the door frame. This method has at least the following problems:

[0005] 1. Using the manual pasting method, it is impossible to ensure the consistency of installation, and it is easy to have problems such as poor installation position of the sealing rubber strip and inability to achieve sealing; moreover, the assembly process is relatively troublesome, resulting in a relatively high labor cost.

[0006] 2. In order to ensure the overall feel of the user when opening and closing the cabinet door, the sealing rubber strip cannot be pasted too thick, resulting in an unsatisfactory sealing effect, and there will still be more water leakage problems in actual operation.

[0007] 3. During use, the sealing rubber strip is prone to problems such as falling off and displacement. Content of the Utility Model

[0008] To solve some or all of the problems existing in the above-mentioned prior art, the present utility model provides a charging and swapping cabinet door with good sealing performance, which includes a cabinet door body and a door frame. The cabinet door body is movably connected to the door frame. A limiting member is fixedly arranged on the cabinet door body. A plurality of positioning posts are arranged on the cabinet door body. Positioning holes are respectively arranged at the corresponding positions of the limiting member and the positioning posts. The positioning posts pass through the corresponding positioning holes. A limiting nut is arranged on each positioning post, and the limiting nut abuts against the limiting member. Sealing rings are respectively arranged at the matching positions of the end face of the limiting member and the door frame. The sealing rings can be in sealing abutment with the door frame. The sealing rings form a closed figure, and the sealing rings are inclined towards the center direction of the limiting member.

[0009] As a further improvement of the present utility model, the sealing ring and the limiting member are of an integrally formed structure.

[0010] As a further improvement of the present utility model, the limiting member is made of a hard plastic material, and the sealing ring is made of a soft plastic material.

[0011] As a further improvement of the present utility model, a circle of reinforcing ribs is arranged on the inner side wall of the limiting member.

[0012] As a further improvement of the present utility model, the number of the positioning posts is 4, and the 4 positioning posts are distributed in a rectangle on the inner side wall of the cabinet door body.

[0013] As a further improvement of the present utility model, the included angle between the sealing ring and the end face of the limiting member is 30° - 70°.

[0014] As a further improvement of the present utility model, a waterproof groove is arranged on the outer side wall of the door frame.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] By installing a limiting member on the cabinet door body, the sealing ring is installed on the cabinet door body. The cooperation mode of the positioning posts and the positioning holes between the limiting member and the cabinet door body can ensure the unified installation position each time, thus ensuring the consistency of assembly. Using nuts can also reduce the assembly difficulty of the cabinet door, thereby improving the assembly efficiency and reducing the labor cost. On the other hand, the sealing ring is inclined on the limiting member, which can improve the sealing performance between the cabinet door and the cabinet body, thereby reducing the possibility of water leakage. During the process of closing the cabinet door, the door frame will squeeze the sealing ring, causing it to deform towards the center direction of the limiting member, so that the sealing ring can be in sealing abutment with the door frame. When water is placed in the cabinet, the water pressure will squeeze the sealing ring, causing it to deform towards the edge of the limiting member, so that the sealing ring fits more tightly with the door frame, thereby preventing water from leaking through the matching gap between the sealing ring and the door frame and improving the sealing performance of the cabinet door.

When assembling the cabinet door body 1, first align the positioning holes 5 on the limiting member 3 with the corresponding positioning columns 4 respectively, so that each positioning column 4 passes through the corresponding positioning hole 5, and then screw each limiting nut 6 onto the positioning column 4 until the limiting nut 6 abuts against the limiting member 3, so that the limiting member 3 and the cabinet door body 1 are connected and fixed in a limiting manner. Through the cooperation of the positioning columns 4 on the cabinet door body 1 and the positioning holes 5 on the limiting member 3, the installation position of the limiting member 3 can be fixed, ensuring the consistency of assembly; and the use of the limiting nut 6 for fixing reduces the difficulty of assembly, thereby improving the assembly efficiency and reducing the labor cost.

[0027] A sealing ring 7 is arranged at the matching position of the end face of the limiting member 3 and the door frame 2. The sealing ring 7 can be in sealing abutment with the door frame 2. The sealing ring 7 forms a closed figure, and the sealing ring 7 is inclined towards the center direction of the limiting member 3. During the process of closing the cabinet door 300, the door frame 2 will squeeze the sealing ring 7, causing it to deform towards the center direction of the limiting member 3, so that the sealing ring 7 can be in sealing abutment with the door frame 2; when water is placed in the cabinet, the water pressure will squeeze the sealing ring 7, causing it to deform towards the edge direction of the limiting member 3, so that the sealing ring 7 fits tighter and tighter with the door frame 2, thereby preventing water from leaking through the matching gap between the sealing ring 7 and the door frame 2, and improving the sealing performance of the cabinet door 300.

[0028] In this embodiment, the sealing ring 7 forms a chamfered rectangular shape; in other embodiments, the sealing ring 7 can also form other sealing figures, such as: circular, oval, etc.

[0029] The included angle between the sealing ring 7 and the end face of the limiting member 3 is 30° - 70°, and the preferred included angle between the sealing ring 7 and the end face of the limiting member 3 is 65°.

[0030] The sealing ring 7 and the limiting member 3 are of an integrally formed structure and can be integrally injection molded by two-color injection molding. In this embodiment, the limiting member 3 is made of a hard plastic material, and the sealing ring 7 is made of a soft plastic material.

[0031] In order to improve the overall structural rigidity of the limiting member 3, a reinforcing rib 8 is provided on the inner side wall of the limiting member 3, and the reinforcing ribs 8 form a closed chamfered rectangle. By providing the reinforcing rib 8, the structural rigidity of the limiting member 3 can be improved, the installation difficulty can be reduced, and the situation of water leakage caused by the deformation of the limiting member 3 can be avoided.
