Description

Technical Field

[0001] The utility model belongs to the field of junction box disassembly and assembly, and specifically relates to a water pump junction box. Background Art

[0002] The junction box of a water pump generally consists of two covers. Usually, after the bottom cover of the junction box is injection molded, it is tapped using a tapping device. After the wiring is completed, the two covers of the junction box are connected and fixed by bolts and threads.

[0003] Chinese patent publication number CN203387341U discloses a water pump junction box, comprising: two hooks are provided on the side of the upper cover, and two slots are provided on the lower cover corresponding to the hooks.

[0004] During use, the water pump junction box disclosed in the application connects and fixes the upper cover and the lower cover by means of a snap-fit ​​method in which a hook is inserted into a slot. When the upper cover and the lower cover are disassembled, the head of the hook needs to be pressed to deform and bend it before it can exit the slot. This disassembly method can easily break the hook, making it difficult to be used for frequent disassembly and assembly. Utility Model Content

DETAILED DESCRIPTION

[0025] The present invention will now be described in further detail with reference to the accompanying drawings.

[0026] See also Figure 1-3 As shown, in this embodiment, a water pump junction box is provided, comprising a first housing 1, a second housing 2 located on one side of the first housing 1, and two connecting members are installed on both sides of the second housing 2;

[0027] Two baffles 4 are installed on both sides of the first shell 1, and a clamping column 401 is installed on the opposite inner side of the two baffles 4. The end of the connecting piece is clamped in the side of the clamping column 401. A guide rod 402 is connected between the two clamping columns 401. Two slide cylinders 5 are elastically fitted on the guide rod 402. The connecting piece is located between the corresponding baffle 4 and the slide cylinder 5. Two plug-in blocks 502 are installed on the opposite outer end surfaces of the two slide cylinders 5. The clamping column 401 is located between the two plug-in blocks 502, and the plug-in blocks 502 are clamped in the connecting piece.

[0028] One aspect of the application of this embodiment is: during disassembly, the two slides 5 on the same side of the first shell 1 are pulled closer to each other, thereby vertically withdrawing the plug 502 from the connecting member, so that the plug 502 cancels the limit on the connecting member, and then the second shell 2 is pulled away from the first shell 1, so that the connecting member is removed from the clamping column 401. After releasing the slide 5, the elastic force of the slide 5 pushes the plug 502 to reset, thereby realizing rapid disassembly of the first shell 1 and the second shell 2. Similarly, the first shell 1 and the second shell 2 can be quickly assembled with reference to the above operations.

[0029] In this embodiment, a positioning frame 201 adapted to the first shell 1 is provided on the inner wall of the second shell 2. One side of the positioning frame 201 is snapped into the first shell 1. The positioning frame 201 facilitates the positioning and installation of the second shell 2 and the first shell 1, while limiting the displacement direction between the two.

[0030] The connecting piece of this embodiment includes a side plate 3 installed on the side of the second shell 2, and a groove 301 is provided on the side of the end of the side plate 3 to match the clamping column 401. The clamping column 401 is clamped in the groove 301. The inner wall side of the groove 301 is provided with a positioning groove 302 to match the insert block 502. The insert block 502 is clamped in the positioning groove 302. The groove 301 and the positioning groove 302 both pass through the side plate 3 in the vertical direction. Through the cooperation between the groove 301 and the clamping column 401, the position of the positioning groove 302 can be easily positioned after the side plate 3 is installed, thereby facilitating the alignment of the positioning groove 302 with the insert block 502.

[0031] In this embodiment, a pressure plate 501 is provided on the side of the slide 5, and anti-slip grooves are provided on the surface of the pressure plate 501. The pressure plate 501 facilitates pulling or pushing the slide 5 to slide along the guide rod 402, and the anti-slip grooves increase the friction between the fingers and the pressure plate 501.

[0032] The guide rod 402 of this embodiment has a square structure in its transverse cross-section, and the slide 5 is provided with a square groove in the vertical direction that is compatible with the guide rod 402. The square groove passes through the slide 5, and the guide rod 402 passes through the square groove. The square groove cooperates with the guide rod 402 to limit the displacement direction of the slide 5, reduce the rotation of the slide 5, and facilitate the insertion of the insert block 502 into the alignment with the positioning groove 302.

[0033] In this embodiment, a spring 6 is provided between the two slides 5 on the same side of the first shell 1. The spring 6 is sleeved on the circumferential side of the guide rod 402. The spring 6 cooperates with the guide rod 402 to reduce the probability of the spring 6 being squeezed by the slide 5 and becoming dislocated or broken, thereby improving the stability of the spring 6 in use.

[0034] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
