Description

Technical Field

[0001] This utility model relates to the field of waterproof structures, and in particular to a waterproof structure for a starter switch. Background Technology

[0002] Currently, Chinese utility model patent CN205194621U discloses a waterproof structure for a starter electromagnetic switch. While this waterproof structure incorporates a locking groove and a boss at the outer shell and push rod to guide and prevent dust from entering, other problems remain during use. For example, the push rod needs to be moved during operation, which can create gaps between the locking groove and the boss, allowing rainwater to seep into the shell, resulting in poor safety. To address these issues, we propose a waterproof structure for a starter switch. Utility Model Content

[0003] The purpose of this invention is to provide a waterproof structure for a starter switch, which solves the problems of poor sealing effect and inconvenience in replacing the waterproof gasket in existing waterproof structures.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a waterproof structure for a starter switch, comprising a switch housing, a fixing plate bolted to the inside of the switch housing, a fixing cylinder installed at the bottom of the fixing plate, a maintenance cover threaded to the bottom of the fixing cylinder, a push rod penetrating through the bottom of the maintenance cover, the top end of the push rod extending into the inside of the switch housing, a base block fixedly sleeved on the surface of the push rod, a fixing spring bolted between the top of the base block and the fixing plate by a spring fixing piece, an installation groove formed on the surface of the base block, and a waterproof gasket bonded inside the installation groove by hot melt adhesive.

[0005] The above technical solution achieves a good sealing effect, preventing rainwater from seeping in through the sliding gap of the push rod, ensuring the safety of the starter switch, and is highly practical. At the same time, it facilitates the replacement of the waterproof gasket, making the operation simple and convenient, eliminating the burden of disassembling and assembling the housing and internal components, and providing good flexibility.

[0006] The present invention is further configured such that: the surface of the inspection cover is integrally injection molded with two connecting parts.

[0007] By adopting the above technical solution, the connection part allows personnel to easily rotate the inspection cover with tools, avoiding slippage and scratches caused by directly clamping the inspection cover.

[0008] The present invention is further configured such that the fixing plate, fixing cylinder and inspection cover are all made of stainless steel.

[0009] Using the above technical solutions, the fixing plate, fixing cylinder, and inspection cover have the characteristics of high strength, low density, and excellent corrosion resistance.

[0010] The present invention is further configured such that: an annular groove is provided at the bottom of the fixing plate, and a sealing ring is bonded to the inside of the annular groove by hot melt adhesive.

[0011] By adopting the above technical solution, the sealing effect between the bottom of the fixing plate and the switch housing can be improved through the setting of the annular groove and the sealing ring.

[0012] The present invention is further configured such that two mounting holes are provided on the top of the fixing plate.

[0013] By adopting the above technical solution, the mounting holes make it easy for personnel to fix the fixing plate to the inside of the switch housing with screws, reducing the trouble of personnel drilling holes temporarily.

[0014] The present invention is further configured such that both the waterproof gasket and the sealing ring are made of natural rubber.

[0015] Using the above technical solutions, waterproof gaskets and sealing rings have the characteristics of high elasticity, excellent mechanical strength, good processing performance, and low temperature resistance.

[0016] The present invention is further configured such that the surface of the waterproof gasket is coated with a lubricant.

[0017] By adopting the above technical solution and using lubricating oil, the friction between the surface of the waterproof gasket and the inner wall of the fixing cylinder can be reduced, which helps the fixing spring to return to its original position smoothly.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. This utility model utilizes the principle that when the push rod is pushed inward, it causes the base block to move inward. As the base block moves inward, it not only compresses the fixing spring through the cooperation of the fixing plate, causing it to contract and deform, but also moves the waterproof gasket in the mounting groove. The surface of the waterproof gasket is in an interference fit with the inner wall of the fixing cylinder. Therefore, rainwater entering from the opening below the inspection cover cannot flow inward through the waterproof gasket, achieving a good sealing effect and preventing rainwater from seeping inward from the sliding gap of the push rod, thus ensuring the safety of the starter switch and making it highly practical.

[0020] 2. This utility model allows for easy replacement of waterproof gaskets when they need to be replaced. First, use a tool to grasp the connector and rotate the inspection cover. During rotation, the inspection cover will separate from the fixed cylinder and fall to the bottom. Then, grasp the push rod and pull it down. When the push rod is pulled down, it will move the base block out of the fixed cylinder. Finally, remove the old waterproof gasket from the mounting groove and insert the new one. This makes it easy to replace the waterproof gasket, and the operation is simple and convenient. It eliminates the burden of disassembling and assembling the shell and internal components and has good flexibility. Attached Figure Description

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

[0026] Example 1:

[0027] refer to Figure 1 , Figure 2 and Figure 3 A waterproof structure for a starter switch includes a switch housing 1, a fixing plate 2 bolted inside the switch housing 1, a fixing cylinder 3 installed at the bottom of the fixing plate 2, and a maintenance cover 4 threaded to the bottom of the fixing cylinder 3. A push rod 5 is provided through the bottom of the maintenance cover 4, and the top of the push rod 5 extends into the interior of the switch housing 1. When the waterproof gasket 8 needs to be replaced, the connecting piece 10 is first grasped with a tool to rotate the maintenance cover 4. During rotation, the maintenance cover 4 will separate from the fixing cylinder 3 and fall to the bottom. Then, the push rod 5 is grasped and pulled down. When the push rod 5 is pulled down, it will move the base block 6 out of the interior of the fixing cylinder 3. Finally, the old waterproof gasket 8 is removed from the mounting groove 7 and the new one is inserted. This facilitates the replacement of the waterproof gasket 8, is simple and convenient to operate, eliminates the burden of disassembling and assembling the housing and internal components, and has good flexibility.

[0028] refer to Figure 1The surface of the inspection cover 4 is integrally injection molded with two connecting parts 10.

[0035] refer to Figure 2and Figure 3 Both the waterproof gasket 8 and the sealing ring 12 are made of natural rubber. The waterproof gasket 8 and the sealing ring 12 have the characteristics of high elasticity, excellent mechanical strength, good processing performance and low temperature resistance.

[0036] refer to Figure 2 The surface of the waterproof washer 8 is coated with lubricant. The lubricant reduces the friction between the surface of the waterproof washer 8 and the inner wall of the fixing cylinder 3, helping the fixing spring 9 to return to its original position smoothly.

[0037] Brief description of the usage process: When the push rod 5 is pushed inward, it will cause the base block 6 to move inward. When the base block 6 moves inward, it will not only compress the fixing spring 9 with the cooperation of the fixing plate 2, causing it to contract and deform, but it will also drive the waterproof gasket 8 in the mounting groove 7 to move together. The surface of the waterproof gasket 8 is in an interference fit with the inner wall of the fixing cylinder 3, so rainwater entering from the opening below the inspection cover 4 cannot flow inward through the waterproof gasket 8.
