Description

A charging box assembly with improved sealing

Technical field:

The utility model relates to the technical field of charging equipment, and more specifically to a charging box assembly with improved sealing.

Background technology:

In existing charging devices, the shell is generally connected to the bottom plate by bolts. In some charging devices, the edges of the shell and the bottom plate generally need to be sealed. The existing sealing method is to apply epoxy resin sealant on the edges of the shell and the bottom plate to achieve sealing, which has low cost. However, for products with this structure, the sealing effect will be lost after the shell and the bottom plate are opened, and sealing cannot be achieved. Re-gluing is required, and the use effect is poor.

Moreover, during use, when used for a long time, it will cause problems such as degumming and the sealing effect will be reduced.

Utility model content:

The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a charging box assembly with improved sealing, which adopts a sealing pad and an elongated sealing strip to achieve extrusion sealing, has good sealing effect and a long sealing time, and after disassembly, only needs to be reinstalled to achieve sealing, and has a good sealing effect.

The solution of the utility model to solve the technical problem is:

A charging box assembly with improved sealing, comprising a lower shell and an upper shell;

The upper shell includes an upper top plate, and side plates extending vertically downward are formed on the left and right sides of the upper top plate;

The lower shell is a bottom horizontal plate portion, which is pressed against the bottom surfaces of the two side plate portions. The bottom surfaces of the side plate portions are formed with long grooves extending forward and backward. The long sealing strips are nested in the long grooves. The bottom surfaces of the long sealing strips are pressed against the top surfaces of the edge portions of the lower shell. The bottom surfaces of the side plate portions are fixedly connected to the top surfaces of the corresponding sides of the lower shell by a plurality of bolts.

The end surfaces of the lower shell and the upper shell on the same side are aligned and fixedly connected with an end plate by bolts, and a sealing gasket is sandwiched between the edge of the inner end surface of the end plate and the corresponding end of the lower shell and the upper shell.

The lower shell and the upper shell form a rectangular box body, the sealing gasket is in the shape of a rectangular frame, which matches and corresponds to the end face of the rectangular box body, and the sealing gasket is clamped between the edge of the inner end face of the end plate and the end face of the rectangular box body.

A plurality of raised heat dissipation strips are formed on the top surface of the upper top plate of the upper shell and the outer wall surface of the side plate portion.

The outstanding effects of the utility model are:

Compared with the prior art, it adopts a sealing pad and a long sealing strip to achieve extrusion sealing, and has a good sealing effect and a long sealing time. Moreover, after disassembly, it only needs to be reinstalled to achieve sealing, and the sealing effect is good.

Specific implementation method:

The present invention is described in detail below in conjunction with the accompanying drawings and specific preferred embodiments, so that the advantages and features of the present invention can be more easily understood by those skilled in the art. These embodiments are only for illustrative purposes and are not intended to limit the scope of the present invention.

Embodiment, as shown in FIGS. 1 to 4 , a charging box assembly with improved sealing includes a lower shell 10 and an upper shell 20;

The upper shell 20 includes an upper top plate, and side plate portions 21 extending vertically downward are formed on the left and right sides of the upper top plate;

The lower shell 10 is a bottom horizontal plate portion, which is pressed against the bottom surfaces of the two side plate portions 21. The bottom surface of the side plate portion 21 is formed with an elongated groove 22 extending forward and backward. The elongated sealing strip 1 is nested in the elongated groove 22. The bottom surface of the elongated sealing strip 1 is pressed against the top surface of the edge of the lower shell 10. The bottom surface of the side plate portion 21 and the top surface of the corresponding side of the lower shell 10 are fixedly connected by multiple bolts.

The end faces of the lower shell 10 and the upper shell 20 on the same side are aligned and fixedly connected with an end plate 30 by bolts, and a sealing gasket 2 is clamped between the edge of the inner end face of the end plate 30 and the corresponding end of the lower shell 10 and the upper shell 20, and the front and rear ends of the elongated sealing strip 1 are tightly attached to the corresponding end faces of the sealing gasket 2.

Furthermore, the lower shell 10 and the upper shell 20 form a rectangular box body, and the sealing gasket 2 is in the shape of a rectangular frame, which cooperates and corresponds to the end face of the rectangular box body, and the sealing gasket 2 is clamped between the edge of the inner end face of the end plate 30 and the end face of the rectangular box body.

Furthermore, a plurality of protruding heat dissipation strips 23 extending forward and backward are formed on the top surface of the upper top plate of the upper shell 20 and the outer wall surface of the side plate portion 21. A plurality of lower heat dissipation protruding strips extending forward and backward are formed on the bottom surface of the lower shell 10.

Furthermore, the outer ends of the plurality of raised heat dissipation strips 23 on the outer side wall of the upper portion of the side plate portion 21 are bent obliquely upward.

Furthermore, two connecting blocks 24 are fixedly connected to the upper top plate of the upper shell 20 by bolts, and two ends of the hand strap 25 are fixed to the two connecting blocks 24, so as to facilitate hand carrying.

A control circuit board is fixed to the bottom surface of the upper top plate of the upper shell 20 .

Furthermore, the left and right sides of the lower shell 10 are formed with outer extension edges 11 extending horizontally outward, and the front and rear parts of the outer extension edges 11 are formed with connecting through holes 12. The connecting through holes 12 can be used to fix the lower shell 10 at the installation position by bolts.

A vent valve 90 is installed on the inner side wall of one side plate portion 21 of the upper shell 20, and the air outlet of the vent valve 90 is connected to the through hole of the side plate portion 21. When the internal air pressure is too high, air can be ventilated through the vent valve 90. The vent valve 90 is a conventional component and will not be described in detail here. Other types of one-way valves can also be installed on it.

The raised heat dissipation strips 23 in this embodiment can increase the heat dissipation effect, so that the heat generated by the control circuit board and the electronic components thereon in the rectangular box can be dissipated, thereby improving the heat dissipation effect.
