Description

Technical Field

[0001] The utility model relates to an auxiliary tool for protecting the glue application oil passage on the fitting surface of a box body. Background Art

[0002] In the combined installation of box bodies that need to be sealed, there are various holes on the mating surface of the assembled boxes, such as connecting threaded holes, oil passage holes, positioning pin holes, etc. Before the combined installation, the mating surface needs to be coated with sealant. When applying the glue, the plane range with a certain diameter around the hole cannot be coated with glue to ensure that there is a certain flow margin after the glue layer 5 is pressed, and to avoid, for example, Figure 1 , Figure 2 as shown, the glue layer is squeezed into the oil passage hole and the positioning pin hole after being pressed, making it difficult to assemble the box bodies.

[0003] However, it is difficult to operate without coating the plane range with the diameter of the hole center, and it requires highly skilled personnel to do so. Most operators are difficult to control, so quality problems such as oil leakage and oil blockage often occur. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides an auxiliary tool for protecting the glue application oil passage on the fitting surface of a box body, which has a simple structure, low cost, can reduce the operation difficulty of the glue application oil passage, and prevent quality problems such as oil leakage and oil blockage.

[0005] The technical solution adopted by the utility model is: an auxiliary tool for protecting the glue application oil passage on the fitting surface of a box body, including a plug and a pressing block. Both the plug and the pressing block are cylindrical, and the diameter of the plug is smaller than that of the pressing block. A conical groove is provided on the lower end surface of the pressing block. The groove is coaxial with the pressing block, and the groove is smaller at the top and larger at the bottom. The diameter of the lower bottom surface of the groove is equal to the diameter of the pressing block. The upper end of the plug is coaxially connected to the lower end of the pressing block.

[0006] Further, a handle is provided on the top surface of the pressing block.

[0007] Further, the handle is cylindrical, coaxial with the pressing block, and has knurling on its side surface.

[0008] Further, the handle, the plug, and the pressing block are made into an integral structure.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model has a simple structure and low cost. When in use, the plug is inserted into the oil passage and the lower end of the pressing block is made to contact the mating surface of the assembled box. Then, the mating surface of the assembled box can be coated with glue. Due to the setting of the pressing block, the part below the pressing block will not be coated with glue, reducing the operation difficulty of the glue application oil passage, and ensuring the glue application quality and preventing quality problems such as oil leakage and oil blockage of the product.

[0017] The following further describes the present utility model with reference to the accompanying drawings.

[0018] As Figure 3-4 shown, it includes a plug 1, a pressing block 2 and a handle 3. The plug 1, the pressing block 2 and the handle 3 are all cylindrical, and the handle 3 can also be of other shapes. The diameter of the plug 1 is smaller than that of the pressing block 2. A conical groove 21 is provided on the lower end surface of the pressing block 2. The groove 21 is coaxial with the pressing block 2, and the groove 21 is smaller at the top and larger at the bottom. The diameter of the lower bottom surface of the groove 21 is equal to the diameter of the pressing block 2. The upper end of the plug 1 is coaxially connected to the lower end of the pressing block 2, and a handle is provided on the top surface of the pressing block. The side surface of the handle is knurled. The handle, the plug and the pressing block are made into an integral structure; they can also be made into a split connection structure.

[0019] As Figure 5-6 shown, when the present utility model is in use, the plug 1 is inserted into the oil passage 6 and the lower end of the pressing block 2 is made to contact the mating surface 4 of the assembled boxes. Then, the mating surface 4 of the assembled boxes can be coated with glue. Due to the setting of the pressing block 2, the part below the pressing block 2 will not be coated with glue, reducing the difficulty of the glue coating operation for the oil passage. Moreover, there is no glue coating layer within a certain range of the oil passage 6 and the oil passage opening. After the assembled boxes are mated, the glue layer outside the range flows into the glue-free area until it reaches the orifice, and no excess glue flows into the oil passage, effectively preventing quality problems such as oil leakage and oil blockage of the product.
