Description

Technical Field

[0001] This utility model belongs to the field of metal rubber node processing technology, and in particular relates to a metal rubber node spray painting protection tool. Background Technology

[0002] Metal-rubber joints refer to a homogeneous, elastic, porous material. They possess both the inherent properties of metal and the elasticity of rubber, giving them unique functions such as excellent damping, filtration, and throttling. To ensure corrosion resistance, the outer surface of the metal-rubber joint is painted. However, in practical use, the following shortcomings still exist:

[0003] 1. During the painting process of metal rubber nodes, the metal rubber nodes are placed directly on the painting workbench, and then the painting parts are used to paint the metal rubber nodes. However, the metal rubber nodes are hollow structures with openings at both ends. In fact, only the outer surface of the metal rubber nodes needs to be painted to achieve corrosion protection. Since the openings of the metal rubber nodes are not sealed, paint will get on the inner wall of the metal rubber nodes, which may even affect the normal use of the metal rubber nodes.

[0004] 2. Secondly, since the metal rubber joints are used in different locations, different outer diameter metal rubber joints will be selected according to the actual needs of the work. Therefore, it is necessary to paint the metal rubber joints with different outer diameters and adjust the protection work to suit the metal rubber joints with different outer diameters.

[0005] To address these issues, we provide a metal-rubber joint spray painting protection fixture. Utility Model Content

[0006] The purpose of this utility model is to provide a metal rubber node spray painting protection tool. By setting a masking component, the openings at both ends of the metal rubber node are sealed to protect the inner wall of the metal rubber node. By setting a spacing adjustment component, the spacing between the blockages can be adjusted according to the outer diameter of the metal rubber node, which is applicable to metal rubber nodes of different sizes, improves practicality, and thus solves the technical problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model relates to a metal rubber node spray painting protection fixture, comprising a base plate, a shielding assembly on the upper surface of the base plate, a mounting bracket mounted on the upper surface of the base plate, a cylinder mounted on the inner top of the mounting bracket, an ear bracket fixedly connected to the lower end of the piston rod at the telescopic end of the cylinder, a lower plate below an upper plate connected to the lower surface of the ear bracket, the lower plate being disposed on the upper surface of the base plate, and plugs equidistantly arranged on the lower surface of the upper plate and the upper surface of the lower plate; an adjusting assembly on the outer wall of the plug, the adjusting assembly comprising a connecting cylinder connected to the outer wall of the plug, a connecting plate connected to the end of a return spring connected to the inner wall of the connecting cylinder, and symmetrically fixed limiting rods near the connecting cylinder on the side wall of the connecting plate; both the upper surface of the upper plate and the lower surface of the lower plate have limiting holes in a rectangular array, and the limiting rods are inserted into the limiting holes.

[0009] The present invention is further configured such that the mounting plate sleeved on the outer side of the substrate has a U-shaped structure, and the upper surface of the mounting plate has screws connected by a rectangular array of threads.

[0010] The present invention is further configured such that the upper surface of the substrate has symmetrically fixed positioning rods, and the two sides of the lower plate have symmetrically fixed positioning rings, the positioning rings being sleeved on the periphery of the positioning rods.

[0011] The present invention is further configured such that the two inner side walls of the mounting bracket have symmetrically opened guide grooves, and the two side walls of the upper plate have symmetrically fixed ear rods, the side of the ear rods away from the upper plate being slidably connected to the inside of the guide grooves.

[0012] The present invention is further configured such that the mounting bracket is an inverted U-shaped structure, the guide groove is a T-shaped groove structure, and the lug is a T-shaped structure.

[0013] The present invention is further configured such that an oil film paper is provided on the lower surface of the upper plate and the upper surface of the lower plate, and a through groove is provided on the upper plate, the lower plate and the upper surface of the oil film paper.

[0014] The present invention is further configured such that the connecting cylinder has symmetrically connected strip plates, the side of the strip plates near the connecting plate has symmetrically opened grooves on both side walls of the connecting plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a blocking component, fits the metal rubber node onto the periphery of the plug on the lower plate. When the cylinder is opened, the piston rod at the telescopic end of the cylinder extends, causing the upper plate to move closer to the lower plate. The plug on the upper plate is fitted inside the metal rubber node, blocking the openings at both ends of the metal rubber node and preventing sprayed paint from adhering to the inner wall of the metal rubber node. This protects the inner wall of the metal rubber node and prevents it from being affected by paint contamination, thus ensuring its future use.

[0017] 2. This utility model, by setting an adjustment component, pulls the connecting plate, extends the reset spring, moves the limiting rod out of the limiting hole, releases the fixation of the blockage position, pushes the connecting plate, and adjusts the spacing between adjacent blockage diameters according to the outer diameter of the metal rubber node, thereby increasing the scope of application and improving practicality.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The cover assembly 2 includes a mounting bracket 201, a cylinder 202, an upper plate 203, a plug 204, and a lower plate 205. When the piston rod at the telescopic end of the cylinder 202 extends, the upper plate 203 moves closer to the lower plate 205. The two corresponding plugs 204 respectively cover the openings at both ends of the metal rubber node, effectively preventing the inner wall of the metal rubber node from being painted, thus achieving a protective effect.

[0032] Specifically, the mounting bracket 201 is mounted on the upper surface of the substrate 1. The inner sidewall of the mounting bracket 201 has a guide groove 201a.
