Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, in particular to a stable sealed wire box for a water pump. Background Art

[0002] Water pumps are important equipment in industrial and agricultural activities. There are many types and models to meet the usage requirements of different types of scenarios. In addition to the necessary mechanical structure, the water pump also includes electrical components such as wires. To ensure the safe operation of the electrical components, the water pump uses mechanical seals and other structures to separate the electrical components from the transmitted fluid. The outside of the water pump needs to use relevant structures to separate the electrical components from the external environment to prevent the electrical components from being corroded, malfunctioning or even scrapped. The structure that separates the electrical components from the external environment of traditional water pumps is mainly a wire box. The wire box is mainly connected to the water pump through threaded structures such as screws and bolts. Some technicians will add a sealing ring between the wire box and the water pump to enhance the sealing effect of the connection position, but the addition of the sealing ring also introduces other problems. For example, the stability of the wire box is reduced, and the sealing ring is likely to shift or fall off accidentally, which will lead to the complete destruction of the sealing. Based on this situation, how to ensure the stability and sealing of the connection between the wire box and the water pump without adding structures is becoming an increasingly urgent problem that relevant technicians need to solve.

[0021] In order to make the description clearer, a stable sealed wire box for a water pump of the present invention is further described in conjunction with the drawings in the specification.

[0022] A stable sealed wire box for a water pump includes a main body 2, characterized in that: corner grooves 4 are provided at the four corners of the outside of the main body 2, a screw hole 1 is provided through the middle of the corner groove 4, an inner cavity 6 is provided at the center position of the main body 2, an inner groove 7 is provided at the inner edge position of the main body 2, and the inner groove 7 is located outside the inner cavity 6.

[0023] Furthermore, an outer sealing plate 5 is provided on the outer side of the inner sink 7, and the outer sealing plate 5 is an extension of the outer periphery of the main body 2 toward the inside. An inner sealing plate 8 is provided on the inner side of the inner sink 7, and the inner sealing plate 8 is an extension of the outer periphery of the inner cavity 6 toward the inside. The outer sealing plate 5 and the inner sealing plate 8 are both protruding compared to the inner sink 7.

[0024] Furthermore, the outer sealing plate 5 and the inner sealing plate 8 are both chamfered on their sides close to each other.

[0025] Furthermore, a central sink 3 is provided at the center of the exterior of the main body 2 .

[0026] Furthermore, a marking area 9 is provided in the middle of the inner cavity 6 .

[0027] Furthermore, the length and width of the main body 2 are both 90 mm, the four corners of the main body 2 are all rounded structures with a radius of 5 mm, and the outer edges of the main body 2 are all rounded structures with a radius of 1 mm.

[0028] The working principle of a stable sealed wire box for a water pump according to the present invention is as follows: the user is set to decide to select this wire box according to the information recorded in the identification area 9. During installation, the fingers are bent to hold the outer side of the main body 2 stably so that the main body 2 corresponds to the corresponding position of the water pump, and the main body 2 is pushed toward the water pump until the inner sinking groove 7 fits with the corresponding position of the water pump. The chamfered structure of the outer sealing plate 5 and the inner sealing plate 8 on one side close to each other enables this process to be completed smoothly. The matching threaded structure such as the screw / bolt is tightened inside the screw hole 1. At this time, the inner sinking groove 7 fits tightly with the corresponding position of the water pump. The outer sealing plate 5, the inner sealing plate 8 and the bolt / screw jointly keep the main body 2 stable. The protruding design of the outer sealing plate 5 and the inner sealing plate 8 blocks the gap at the connection position. The tight fit of the inner sinking groove 7 and the corresponding position of the water pump together keep the connection position well sealed. The installation process can be completed at this point, and the stability and sealing of the connection between the wire box and the water pump are guaranteed.

[0029] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited to them. Any changes or substitutions that do not require creative work should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
