Description
The present invention relates to a paint stay, and more particularly, to a paint stay using a gas cylinder that holds a bonnet, a door, and a trunk lid of a vehicle in an open state during a painting process of a vehicle.
Generally, since the appearance of a vehicle is made of a metal material, it is easily corroded when exposed to high humidity, temperature, and various chemicals. Such corrosion phenomenon is getting worse due to acid rain or ultraviolet rays due to environmental pollution recently. In order to prevent the appearance of the vehicle from being corroded, a painting process is performed in the manufacturing process of the vehicle. In addition to the purpose of preventing the corrosion of the vehicle, the coating process is carried out for the purpose of improving the gloss effect by embedding a large number of pores existing on the surface of the vehicle, and basically includes the pretreatment process, electrodeposition process, middle process and top process do.
During the painting process of the vehicle, the pretreatment process and the electrodeposition process are carried out in such a manner that the car body is immersed in a chamber filled with a coating material, so that a moving part such as a bonnet, a door (front / rear / hatchback door) The process proceeds in a closed state. On the other hand, in the sealer process for sealing the panel connection portion of the vehicle body, the deadner process for undercoating the lower portion of the door, and the moving portion for the intermediate process and the overhead process, the movable portion is opened by a fixed stay (also called an iron- The work is done. For example, in the intermediate process and the overhead process, the operator opens the moving part of the vehicle and then keeps it open through the fixed stay, and then applies the coating process to the inner surface of the open moving part by using the spray gun for painting Conduct. After completion of the painting process on the inner surface of the moving part, the operator must manually remove the fixing stay and close the moving part.
As described above, in the conventional moving part painting process, the worker repeatedly performs the operation of opening and closing the hood by using the fixing stay, thereby frequently causing the worker's musculoskeletal system to be damaged. Also, in the process of repeatedly performing the opening and closing operations of the moving parts of the vehicle during the painting process, the loose powder is fixed to the painting area due to the friction generated when the moving part and the fixing stay collide with each other, It is necessary to carry out an additional repair work to remove the flour and thus the workability is deteriorated and the quality of the coating is deteriorated.
In order to solve such a problem, recently, a gas cylinder (or a gas shock absorber, a gas spring) has been used as a stay for a moving part which is easily detachable from a vehicle during a painting process. In other words, when painting the vehicle, the gas cylinder is mounted in the proper position to keep the moving part open. However, during the coating process, the gas cylinder is exposed to harmful substances such as pretreatment chemicals, primers, and paints, which has adversely affected operation.
Accordingly, in order to prevent the contamination of the gas cylinder during the painting process of the vehicle, a replacement paint-line gas cylinder called "paint slave" is used only during the coating process, and after the coating process is completed, A method of replacing with a gas cylinder was used. Replacement paint-line gas cylinders have been separated from the vehicle after the painting process and are washed and reused, or when they are destroyed, they are disposed of. Therefore, there is a problem that the manufacturing cost and time are consumed due to additional handling and processing steps.
Korean Patent Laid-Open No. 10-2006-0113653 (published on November 11, 2006) provided a removable protective sleeve for a gas cylinder to solve the problem of a conventional replacement paint-line gas cylinder. The protective sleeve proposed in Korean Patent Laid-Open No. 10-2006-0113653 is flexible, can not penetrate the liquid spray, and can be removed from the gas cylinder after the painting process is completed using a material that can withstand high temperatures in the coating process This solves the problem of manufacturing costs and time consuming due to additional handling and processing steps.
However, in Korean Patent Publication No. 10-2006-0113653, since the protective sleeve is mounted so as to completely cover the gas cylinder, it is troublesome to mount the protective gas cylinder on the vehicle in a state that the protective sleeve is covered, Additional work was still required because the sleeve had to be removed from the gas cylinder.
Furthermore, in order to mount the gas cylinder on the bracket, it is necessary to align the position of the gas cylinder while adjusting the position by rotating the rod of the gas cylinder. . However, in the protective sleeve disclosed in Korean Patent Laid-Open Publication No. 10-2006-0113653, when the gas cylinder is completely covered or coupled to the cylinder body (that is, the gas filling portion), the protective sleeve is twisted in the rotating direction during the rotation of the gas cylinder, Lt; RTI ID = 0.0 > operation. ≪ / RTI >
Therefore, the present invention has been proposed in order to solve the problems of the prior art, and it is an object of the present invention to provide a gas cylinder which does not affect operation (linear movement and rotational movement) of a gas cylinder, And it is an object of the present invention to provide a coating stay using a gas cylinder capable of withstanding a high temperature in a drying process of a coating process.
According to an aspect of the present invention, A piston rod fixed to the piston provided in the body and linearly moving; A rotation coupling pipe coupled to an outer surface of the body so as to be rotatable along a circumferential surface of the body; And a protective cover installed to cover between the body and the piston rod, one side of which is fixed to the outside of the rotary coupling pipe and the other side of which is coupled to the end of the piston rod. Thereby providing a coating stay used.
Preferably, the apparatus further comprises first and second fixing rings fixed to the outer surface of the body with the rotary coupling pipe interposed therebetween to prevent the rotary coupling pipe from moving in the longitudinal direction along the outer surface of the body .
Preferably, the first and second stationary rings are fixed to the first and second stationary grooves recessed inwardly on the outer surface of the body, and a part of the first and second stationary rings are coupled to protrude upward from the first and second stationary grooves . ≪ / RTI >
Preferably, the sleeve further includes a sleeve having one side fixed to the body and the other side formed in a tubular shape extending from the body in a direction in which the piston rod protrudes to the outside, and covering the space between the body and the piston rod. can do.
Preferably, a coupling protrusion is provided on an inner surface of one side of the sleeve, and is fixed to the third fixing groove recessed inwardly on the outer surface of the body.
Preferably, the protective cover is made of a synthetic resin material or a synthetic fiber material having a flexible material or a corrugated pipe structure and having heat resistance to withstand the temperature applied during the painting process and corrosion resistance not to be corroded by harmful substances can do.
As described above, according to the present invention, there is provided a rotary coupling pipe that is coupled to an outer surface of a body so as to be rotatable along a circumferential surface of a body, and a rotary coupling pipe which is installed to cover between the body and the piston rod, And a protective cover which is fixed to the outside of the piston rod and is coupled to the end portion of the piston rod, thereby preventing harmful substances from penetrating into the inside of the body during the coating process, The protective cover is twisted to prevent the gas cylinder from malfunctioning.

An example of such a sealing ring has been proposed in Korean Patent Publication No. 10-2010-0024202 (published on March 30, 2010). However, the seal ring proposed in Korean Patent Laid-Open No. 10-2010-0024202 has caused a rise in the product price due to the use of relatively expensive chemical resistant fluor rubber. Accordingly, the present invention uses an inexpensive silicone material having a heat resistance that can withstand approximately 200 DEG C as a sealing ring, and is less expensive than fluorine rubber.
