Description

Technical Field

[0001] This utility model relates to the field of buckle technology, and in particular to a W-type waterproof buckle. Background Technology

[0002] Clips are a common structure used for snapping together parts and are used in the connection of multiple parts. Most of the existing connections between sheet metal parts in automobiles or home appliances are bolted, which is cumbersome, time-consuming and laborious to disassemble and assemble, greatly increasing the difficulty of the workers' work. Moreover, clips are suitable for sheet metal parts, but after the clips are installed, the sheet metal holes are not waterproof, and rust is easily generated inside the sheet metal parts.

[0003] In the prior art, CN219655034U discloses a W-type waterproof buckle. By inserting two wing plates into the mounting hole and pressing the base plate, the wing plates are forced into the mounting hole. At the same time, the sealing ring also fits tightly around the mounting hole, thus preventing rainwater from entering the mounting hole. The sealing ring itself is elastic. The sealing ring is engaged with the first retaining ring and the first retaining groove, and the second retaining ring is engaged with the second retaining groove, so that the sealing ring and the base are tightly closed, further preventing rainwater from seeping through the gap between the sealing ring and the base.

[0004] However, the aforementioned W-type waterproof buckle only uses a single sealing ring for sealing, which is prone to sealing failure. Moisture can easily seep into the buckle from the connection gap. In addition, the buckle is composed of multiple scattered parts, which not only increases the difficulty of operation during insertion and removal, but also damages the buckle structure. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a W-type waterproof buckle.

[0006] The present invention adopts the following technical solution.

[0007] A W-shaped waterproof buckle includes a base plate, a base, and a chassis. The top of the base plate is connected to one end of the base, and the other end of the base is connected to the chassis. A connecting plate is connected to the top of the base. The buckle is characterized in that: a sealing plate is provided on the outer side of the chassis, a waterproof gasket is installed on the top of the chassis, and the waterproof gasket is located inside the sealing plate; and locking blocks are provided on both sides of the connecting plate, with the top edge of the sealing ring higher than the center line of the inclined surface of the lower section of the locking block.

[0008] To further improve the stability of the sealing disc, a raised ring is provided on the outer side of the chassis. The center of the chassis and the raised ring overlap, and the raised ring and the chassis are an inseparable integral structure.

[0009] Preferably, the sealing disc includes a fixed disc and a sealing ring. The fixed disc is located at the lower end of the sealing disc, and the inner wall of the fixed disc fits against the outer surface of the raised ring and completely covers the raised ring.

[0010] To further extend the waterproof range of the sealing disc, a sealing ring is connected above the fixed disc. The sealing ring is an outwardly expanding circular ring located at the upper end of the sealing disc.

[0011] Preferably, the angle formed by the outer surface of the fixed disk and the outer surface of the sealing ring is an obtuse angle.

[0012] To further improve the stability of the fixed waterproof gasket after installation, the waterproof gasket has a through hole in the center, and the inner wall of the through hole is in contact with the outer surface of the connecting plate.

[0013] Preferably, the waterproof gasket is made of EPDM material.

[0014] To further improve installation efficiency, the card block includes a snap-fit ​​plate and a plug-in plate. The plug-in plate is connected to the connecting plate, and the end of the plug-in plate away from the snap-fit ​​plate has a rounded corner.

[0015] To further enhance the stability of the snap-fit ​​connection, the angle between the snap-fit ​​block and the connecting plate is an acute angle.

[0016] To further enhance the overall strength of the card block, the base plate, base, chassis, connecting plate, and card block are an inseparable integrated structure.

[0017] Beneficial effects: By setting up a sealing plate and a waterproof gasket to form a double waterproof structure, the overall waterproof performance of the buckle is significantly improved. It can effectively prevent water from seeping in from the connection gap. In addition, the unique design of the buckle block facilitates the quick insertion and installation of the buckle and the corresponding parts, improving the installation efficiency. At the same time, it enhances the firmness of the snap-fit, taking into account both the ease of installation and the stability of the connection. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Combination Figures 1-6 As shown, a W-shaped waterproof buckle includes a base plate 1, a base 2, and a chassis 3. The top of the base plate 1 is connected to one end of the base 2, and the other end of the base 2 is connected to the chassis 3. A connecting plate 4 is connected to the top of the base 2. The characteristic feature is that a sealing plate 5 is provided on the outer side of the chassis 3, a waterproof gasket 6 is installed on the top of the chassis 3, and the waterproof gasket 6 is located inside the sealing plate 5. Blocks 7 are provided on both sides of the connecting plate 4, and the top edge of the sealing ring 10 is higher than the center line of the inclined surface of the lower section of the block 7.

[0028] The chassis 3 has a raised ring 8 on its outer side. The center of the chassis 3 and the raised ring 8 overlap, and the raised ring 8 and the chassis 3 are an inseparable integral structure.

[0029] The sealing disk 5 includes a fixed disk 9 and a sealing ring 10. The fixed disk 9 is located at the lower end of the sealing disk 5. The inner wall of the fixed disk 9 fits against the outer surface of the raised ring 8 and completely covers the raised ring 8.

[0030] A sealing ring 10 is connected above the fixed disk 9. The sealing ring 10 is an outwardly expanding ring and is located at the upper end of the sealing disk 5.

[0031] The inner angle formed by the outer surface of the fixed disk 9 and the outer surface of the sealing ring 10 is an obtuse angle, preferably 120°.

[0032] The waterproof gasket 6 has a through hole 11 in the center, and the inner wall of the through hole 11 is in contact with the outer surface of the connecting plate 4.

[0033] Among them, the waterproof gasket 6 is made of EPDM material.

[0034] The card block 7 includes a card plate 12 and a plug plate 13. The plug plate 13 is connected to the connecting plate 4, and the end of the plug plate 13 away from the card plate 12 has a rounded corner.

[0035] The angle between the snap-fit ​​block 7 and the connecting plate 4 is an acute angle.

[0036] Among them, the base plate 1, the base 2, the chassis 3, the connecting plate 4, and the locking block 7 are an inseparable integrated structure.

[0037] By constructing a double waterproof structure, namely setting a sealing disc 5 and a waterproof gasket 6, and extending outward through a sealing ring 10, the waterproof performance of the buckle is significantly improved, effectively preventing moisture from seeping through the connection gaps. Simultaneously, the rounded corner design at one end of the insertion plate 13 allows the locking block 7 to be inserted into the mounting hole more easily, thereby improving installation efficiency. Since the angle between the locking block 7 and the connecting plate 4 is an acute angle, this further enhances the overall structural stability of the buckle during fixing. Furthermore, the inseparable integrated structure formed by the base plate 1, base 2, chassis 3, connecting plate 4, and locking block 7 not only improves the overall structural strength of the buckle, preventing damage to the buckle structure when inserting or removing it, but also effectively reduces production costs.
