Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of adhesive devices, and specifically relates to a universal adhesive device for rubber parts. Background Technology
[0002] In actual production, some products have airtightness requirements and require opening to replace components and accessories during use. For example, the battery compartment assembly requires opening the battery cover to replace the battery when it is depleted. Therefore, the product design needs to incorporate a rubber sealing gasket on the battery cover for sealing. To prevent the rubber sealing gasket from detaching from the battery cover when it is opened, silicone rubber 704 is applied to the contact area between the rubber sealing gasket and the battery cover to secure it. However, due to the elasticity of the rubber component, if it is not properly compressed after applying the adhesive, the rubber component can easily warp, leading to water ingress during environmental tests such as immersion and salt spray. Even with auxiliary compression after applying the adhesive, improper compression force can still cause water ingress during immersion and salt spray tests. Therefore, developing a universal adhesive device for rubber components with adjustable compression force to solve this problem is of great significance. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of existing rubber bonding devices and provide a universal rubber bonding device with adjustable clamping force, high positioning accuracy, strong practicality, and convenient operation.
[0004] To achieve its purpose, the technical solution adopted by this utility model is as follows: A universal adhesive device for rubber parts is designed. The adhesive device includes a fixed plate, which is rectangular. A limiting plate is provided on one of the short sides of the fixed plate. Slide rails are provided on both sides of the long side of the fixed plate, and slider seats are slidably arranged within the two slide rails. Each slider seat has a limiting groove. A support block is provided on the other side of the short side of the fixed plate. The support block is inverted "L" shape. A screw hole is provided at the top center of the support block, and a trimming ring is provided at the top of the screw hole. A locking screw passes downward through the screw hole and is threaded into it. A limiting boss is provided on the upper section of the locking screw, and a guide block is rotatably connected to the lower end of the locking screw. A cuboid boss is designed at the rear end of the guide block, and a guide groove is provided on the side of the support block, with the cuboid boss extending into the guide groove.
[0005] Furthermore, a connecting post is provided on the top of the guide block, and an annular groove is provided on the connecting post. The inside of the locking screw is hollow. The connecting post is inserted into the inside of the locking screw and forms a rotatable connection with the locking screw through a limiting pin screwed into the annular groove from the outside of the locking screw.
[0006] Furthermore, a handle is provided at the top of the locking screw.
[0007] This utility model adopts the above-mentioned technical solution, including a fixed plate, a limiting plate, a slide rail, a support block, a locking screw, a guide pressure block, a trimming ring, a slider seat, limiting pins, screws, and other parts. The fixed plate is equipped with a limiting plate, a support block, and a slide rail. The slider seat can slide back and forth under the guidance of the slide rail. The slider seat first slides forward to the limiting plate, and the rubber part to be pressed after being coated with adhesive is placed into the limiting groove of the slider seat for positioning. The slider seat then slides backward to the support block. Next, the locking screw is rotated clockwise. The locking screw drives the guide pressure block to move vertically downward under the guiding and limiting action of the support block's guide groove until the limiting boss of the locking screw touches the upper end face of the trimming ring, at which point the guide pressure block stops moving. Two limiting pins pass through the locking screw and are locked in the annular groove at the top of the guide pressure block, preventing the guide pressure block from coming out of the locking screw. The locking screw and limiting pins can rotate around the annular groove of the guide pressure block. A cuboid boss is designed at the rear end of the guide block. This boss slides up and down within the guide groove of the support block, precisely positioning the guide block and ensuring a consistent distance between the outer contour of the guide block and the outer contour of the rubber part. A trimming ring is designed between the locking screw and the support block. The clamping force of the adhesive device is adjusted by changing the thickness of the trimming ring. If the clamping force is too high, the rubber part will deform significantly, and the silicone rubber 704 will be squeezed out from the adhesive gap, resulting in an unstable fixation of the rubber part. If the clamping force is too low, the rubber part will warp, making it difficult to guarantee the airtightness of the product. In summary, this utility model of a universal adhesive device for rubber parts features adjustable clamping force, high positioning accuracy, strong practicality, and convenient operation. Attached Figure Description
[0008] Figure 1 This is a schematic diagram of the overall structure of this utility model; Figure 2 This is an axonometric view of the present invention; Figure 3 This is a side view of the guide block in this utility model. Detailed Implementation
[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments, and its structure and advantages will become clearer.
[0010] See Figure 1-3A universal adhesive device for rubber parts is disclosed. The adhesive device includes a fixed plate 12, which is rectangular. A limiting plate 10 is provided on one of the short sides of the fixed plate 12 and is fixed by screws 11. Slide rails 9 are provided on both sides of the long side of the fixed plate 12, and slider seats 8 are slidably arranged in the two slide rails 9. The slider seats 8 are provided with limiting grooves. A support block 3 is provided on the other side of the short side of the fixed plate 12. The support block 3 is inverted "L" shape. A screw hole is provided at the top center of the support block 3. A trimming ring 2 is provided at the top of the screw hole. A locking screw 1 passes downward through the screw hole and is threaded into the screw hole. A limiting boss 13 is provided on the upper section of the locking screw 1. A guide pressure block 4 is rotatably connected to the lower end of the locking screw 1. A cuboid boss 4.1 is designed at the rear end of the guide pressure block 4. A guide groove 3.1 is provided on the side of the support block 3, and the cuboid boss 4.1 extends into the guide groove 3.1.
[0011] Furthermore, the top of the guide block 4 is provided with a connecting post, and the connecting post is provided with an annular groove 4.2. The inside of the locking screw 1 is hollow. The connecting post is inserted into the inside of the locking screw 1 and forms a rotatable connection with the locking screw 1 through the limiting pin 5 that is screwed into the annular groove 4.2 from the outside of the locking screw 1.
[0012] Furthermore, a handle is provided at the top of the locking screw 1.
[0013] In use, the slider seat 8 can slide back and forth under the guidance of the slide rail 9. The slider seat 8 first slides forward to the limiting plate 10, and the battery cover 7 containing the rubber part 6, which needs to be pressed after being coated with glue, is placed into the limiting groove of the slider seat 8 for positioning. The slider seat 8 then slides backward to the support block 3. Then, the locking screw 1 is rotated clockwise. The locking screw 1 drives the guide pressure block 4 to move vertically downward under the guiding and limiting action of the guide groove 3.1 of the support block 3 until the limiting boss 13 of the locking screw 1 touches the upper end face of the trimming ring 2. At this time, the guide pressure block 4 stops moving. The two limiting pins 5 pass through the locking screw 1 and are locked in the annular groove 4.2 at the top of the guide pressure block 4 to prevent the guide pressure block 4 from coming out of the locking screw 1. The locking screw 1 and the limiting pins 5 can rotate around the annular groove 4.2 of the guide pressure block 4. The rear end of the guide block 4 is designed with a cuboid boss 4.1, which slides up and down within the guide groove of the support block 3, serving to precisely position the guide block 4 and ensure that the distance between the outer contour line of the guide block 4 and the outer contour line of the rubber part 6 is consistent. A trimming ring 2 is designed between the locking screw 1 and the support block 4. The clamping force of the adhesive device can be changed by adjusting the thickness of the trimming ring 2. If the clamping force is too large, the rubber part will deform greatly, and the silicone rubber 704 will be squeezed out from the glue storage gap, making the rubber part 6 unstable. If the clamping force is too small, the rubber part 6 will warp, and the airtightness of the product will not be guaranteed. In summary, this utility model of a universal adhesive device for rubber parts has adjustable clamping force, high positioning accuracy, strong practicality, and convenient operation.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many modifications under the guidance of the present invention and without departing from its spirit, and all such modifications are within the protection scope of the present invention.
