Description

Technical Field

[0001] This utility model relates to the field of waterproof box technology, and in particular to a structure that achieves the locking of the upper and lower covers through a snap fastener. Background Technology

[0002] Waterproof boxes are used to house important electronic components (such as memory chips) to prevent them from failing due to water damage. Most existing waterproof boxes are assembled using screws, which requires tightening screws, is time-consuming and labor-intensive, and the small screws and holes make assembly and positioning difficult.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a structure that uses a snap-fit ​​mechanism to achieve the interlocking of the upper and lower covers, thereby enabling quick and accurate assembly of the waterproof box and improving assembly speed.

[0005] The technical solution of this utility model is as follows: A structure for engaging an upper and lower cover via a snap-fit ​​mechanism is provided, comprising: an upper cover, a lower cover, several vertical plates connected to the lower cover, and a sealing ring; the vertical plates are disposed on at least two opposite sides of the lower cover, and snap-fits are provided on the inner side of the vertical plates; the snap-fits hold the upper cover in place, and the sealing ring is sandwiched between the upper and lower covers. During assembly, the sealing ring is placed on the lower cover, then the upper cover is placed on the sealing ring, and the upper cover is pressed down, causing the upper cover to be snapped in place, thus achieving the engagement of the upper and lower covers. This solution uses a snap-fit ​​mechanism to engage the upper and lower covers, making assembly very simple and effectively improving assembly efficiency.

[0006] Furthermore, the upper surface of the buckle is a first inclined surface. The first inclined surface can guide the downward movement of the upper cover, facilitating the upper cover to be pressed into the buckle.

[0007] Furthermore, the lower surface of the upper cover is provided with a second inclined surface, which cooperates with the first inclined surface. The function of the second inclined surface is similar to that of the first inclined surface, providing guidance for the downward movement of the upper cover. When it cooperates with the first inclined surface, it can better press the upper cover under the buckle.

[0008] Furthermore, the side of the upper cover is provided with several raised portions, which engage with the buckle. Preferably, the second inclined surface is provided on the lower surface of the raised portion.

[0009] Furthermore, the lower cover, which is connected to the vertical plates, has at least two vertical plates connected to its side. The upper cover is provided with a positioning piece, which engages with the grooves between the two vertical plates on the same side of the lower cover. The engagement of the positioning piece with the grooves facilitates the accurate placement of the upper cover and facilitates assembly.

[0010] Furthermore, the upper cover is provided with an upper sealing groove, the lower cover is provided with a lower sealing groove, and the sealing ring is sandwiched between the upper sealing groove and the lower sealing groove.

[0011] Furthermore, the sealing ring is interference-fitted with the upper and lower sealing grooves.

[0012] By adopting the above solution, this utility model provides a structure that achieves the locking of the upper and lower covers through a snap-fit ​​mechanism. The snap-fit ​​method makes the assembly very simple and can effectively improve assembly efficiency. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of one embodiment of the present invention;

[0014] Figure 2 for Figure 1 Cross-sectional view of an embodiment. Detailed Implementation

[0015] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides a structure for locking an upper and lower cover using a snap-fit ​​mechanism, comprising: an upper cover 10, a lower cover 11, several vertical plates 12 connected to the lower cover 11, and a sealing ring 13; the vertical plates 12 are disposed on at least two opposite sides of the lower cover 11, and snap-fits 14 are provided on the inner side of the vertical plates 12; the snap-fits 14 hold the upper cover 10 in place and clamp the sealing ring 13 between the upper cover 10 and the lower cover 11. During assembly, the sealing ring 13 is placed on the lower cover 11, then the upper cover 10 is placed on the sealing ring 13, and the upper cover 10 is pressed down, so that the upper cover 10 is secured by the snap-fits 14, thus achieving the locking of the upper cover 10 and the lower cover 11. This solution uses a snap-fit ​​mechanism to lock the upper cover 10 and the lower cover 11, which is very simple to assemble and can effectively improve assembly efficiency. The space enclosed by the sealing ring 13, the upper cover 10, and the lower cover 11 is used to place a waterproof chip 30, which can transmit data through a flexible circuit board 31.

[0017] In this embodiment, the upper surface of the buckle 14 is a first inclined surface 21. The first inclined surface 21 can provide guidance for the downward movement of the upper cover 10, making it easier for the upper cover 10 to be pressed into the buckle.

[0018] In this embodiment, the lower surface of the upper cover 10 is provided with a second inclined surface 22, and the first inclined surface 21 cooperates with the second inclined surface 22. The function of the second inclined surface 22 is similar to that of the first inclined surface 21, which can provide guidance for the upper cover 10 to move downward. After cooperating with the first inclined surface 21, the upper cover 10 can be pressed under the buckle 14 more effectively.

[0019] In this embodiment, the side of the upper cover 10 is provided with a plurality of raised portions 15, which cooperate with the buckle 14. Preferably, the second inclined surface 22 is provided on the lower surface of the raised portion 15.

[0020] In this embodiment, the lower cover 11, which is connected to the vertical plates 12, has at least two vertical plates 12 connected to its side. The upper cover 10 is provided with a positioning piece 16, which engages with the groove 17 between the two vertical plates 12 on the same side of the lower cover 11. The engagement of the positioning piece 16 with the groove 17 facilitates the placement of the upper cover 10 in the correct position and facilitates assembly.

[0021] In this embodiment, the upper cover 10 is provided with an upper sealing groove, the lower cover 11 is provided with a lower sealing groove, and the sealing ring 13 is sandwiched between the upper sealing groove and the lower sealing groove. The sealing ring 13 is interference-fitted with the upper sealing groove and the lower sealing groove.

[0022] In summary, this utility model provides a structure that achieves the locking of the upper and lower covers through a snap-fit ​​mechanism. The snap-fit ​​method makes assembly very simple and can effectively improve assembly efficiency.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
