[0001] The utility model relates to the technical field of metal oxidation, in particular to a device for oxidizing and plugging holes. Background Art

[0002] At present, in the process of surface treatment of metal products, trapezoidal rubber plugs and convex rubber plugs are usually used to seal and protect holes that do not require surface treatment.

[0003] As shown in the accompanying drawings Figure 1 As shown, the existing sealing method has the following problems: first, during the use of the trapezoidal rubber plug, the product hole is not a complete hole, resulting in loose sealing and poor protection effect; second, the convex rubber plug needs to pass through the hole completely, making the installation process difficult and the operation efficiency low.

[0004] Obviously, when protecting through holes on surface-treated products, the existing technology has problems such as difficult operation, low efficiency and poor protection effect.

[0005] Therefore, in order to achieve rapid and effective sealing and protection of surface-treated pores, we propose an oxidation pore blocking device. Utility Model Content

[0010] Furthermore, the deformable member includes a pipe, and a wedge portion with symmetrical ends is formed in the inner hole of the pipe;

[0011] A deformation groove is further provided on the end surface of the pipe, and the deformation groove penetrates along the outer circumference of the pipe into the inner hole thereof.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Reference Figure 2-5 This is an embodiment of the present invention, which discloses an oxidation hole plugging device, which is used to solve the problems of difficult operation, low efficiency and poor protection effect when protecting through holes on metal products. Specifically, the device includes a sealing member 2 and a deformation member 3 placed in a through hole 11 of a product 1;

[0028] The seal 2 has a hole inside for accommodating the deformable member 3 , wherein a driving structure is also provided on the inner side of the deformable member 3 , and the driving structure is used to drive the deformable member 3 to deform and expand to resist the deformation of the seal 2 and fit into the through hole 11 .

[0029] In some embodiments, the deformable member 3 of the present invention includes a tube 31 , and a wedge portion 32 symmetrical at both ends is formed in the inner hole of the tube 31 ;

[0030] A deformation groove 33 is further provided on the end surface of the pipe 31 , and the deformation groove 33 extends along the outer circumference of the pipe 31 into the inner hole thereof.

[0031] Specifically, the tube 31 described in this embodiment can be set as a rubber tube or a metal tube. Through the design of the deformation groove 33, its deformation space can be provided to produce deformation when the driving structure conflicts, and then expand to conflict with the seal 2. Of course, the seal 2 described in this embodiment is preferably set as a silicone part, which uses its own elastic ability to achieve outward expansion to achieve close contact with the inner wall of the through hole 11.

[0032] On the basis of the above embodiment, the deformation groove 33 in this embodiment includes a plurality of deformation grooves 33, and the plurality of deformation grooves 33 are distributed on the pipe 31 in a symmetrical staggered structure;

[0033] The deformation groove 33 includes a hole portion 331 and a groove portion 332 communicating with the hole portion 331 . The groove portion 332 extends to a side end of the tube 31 .

[0034] In a preferred embodiment, the driving structure of the present invention includes a first handle 4 and a second handle 5;

[0035] A frustum portion 6 is formed on the opposing surfaces of the first handle 4 and the second handle 5. The two frustum portions 6 are respectively inserted into the two ends of the deformable member 3. Specifically, the frustum portion 6 in this embodiment abuts against the above-mentioned wedge portion 32. In this way, when the first handle 4 and the second handle 5 move relative to each other, the two frustum portions 6 abut against the two wedge portions 32, so that the entire deformable member 3 is deformed.

[0036] On the basis of the above embodiment, in order to facilitate the control of the relative movement of the first handle 4 and the second handle 5, in this embodiment, a screw 41 is fixedly installed on the frustum portion 6 of the first handle 4, and a threaded hole 51 threadedly connected to the screw 41 is opened on the frustum portion 6 of the second handle 5.

[0037] That is, during operation, the deformable member 3 is first inserted into the sealing member 2 and assembled as a whole into the through hole 11 of the product 1, and the screw 41 of the first handle 4 is connected to the threaded hole 51 of the second handle 5, and the entire hole blocking protection device is assembled;

[0038] The assembly steps include: passing the frustum portion 6 on the first handle 4 and the second handle 5 through the interior of the deformable part 3, and then tightening the first handle 4 and the second handle 5 by threading them into the threaded hole 51 through the screw 41, thereby squeezing the deformable part 3, so that the deformable part 3 expands and squeezes the seal 2. After deformation, the seal 2 is deformed and fits tightly against the inner wall of the through hole 11, thereby protecting the through hole 11 of the product 1.

[0039] Specifically, this embodiment further includes a force-adding rod 7, the end of which has a sleeve 71, and a plurality of protrusions 72 are formed in the sleeve 71;

[0040] A plurality of grooves 42 are provided on the outer periphery of the first handle 4 and the second handle 5. The sleeve 71 is sleeved on the outer side of the first handle 4 and the second handle 5. The protrusion 72 is coupled and adapted with the groove 42. The protrusion 72 is engaged with the groove 42 to provide a clamping force to avoid idling.

[0041] When there is a torque requirement for the first handle 4 and the second handle 5, a force rod 7 is required to make the assembly torque greater. To disassemble the product, loosen the threads of the first handle 4 and the second handle 5, and then take the entire device out of the hole. The disassembly is completed.

[0042] In summary, in the present invention, the driving structure is used to control the deformation expansion of the deformable part 3, so that the deformable part 3 expands and squeezes the sealing part 2. After deformation, the sealing part 2 is deformed and fits tightly against the inner wall of the through hole 11, thereby realizing the protection of the through hole 11 of the product 1. In this way, the through hole 11 that needs to be protected in the surface treatment product 1 can be quickly and effectively sealed and protected. The overall structural design is simple and easy to operate, which effectively improves the convenience and efficiency of the protection operation of the through hole 11.

[0043] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
