Abstract
The invention provides a method for mounting an emergency hammer and an emergency unlocking cover plate on a lateral top board of a metro vehicle. The method comprises the following steps of firstly, opening holes on the cover plate and the lateral top board, and cleaning dirt in the holes; aligning a hole on the surface of the cover plate to a hole on a vehicle inner decoration board in position; and sequentially plugging plastic rivets in a horizontal direction and a vertical direction into the holes, wherein the diameter of an outward-convex part at the middle part of each plastic rivet is larger than the diameter of each one of the hole of the cover plate and the lateral top board, the front end of each plastic rivet is conical, and a long-tapered notch is arranged at the middle; and powerfully pressing the plastic rivets in all the plugging holes so that the surface flatness of the cover plate and the lateral top board are the same and all the plastic rivets are completely tightened and firmed without seams. According to the method provided by the invention, the diameter of the outward-convex part at the middle part of each plastic rivet is more than the diameter of each one of the hole of the cover plate and the lateral top board, and the front end of each plastic rivet is conical so that the plastic rivets are easy to enter the hole; when the plastic rivets slide to the middle part due to an external force, and the plastic rivets powerfully press the walls of the holes; a long conical opening is arranged at the middle part of each plastic rivet; and groove parts at the middle parts of the plastic rivets are elastically deformed due to extrusion, and a lasting force is generated so that the plastic rivets can not retract from the rivet holes and do not release even shaking.
Description
Technical field
The present invention relates to installing and fixing of a kind of railcar side roof safety hammer and emergency release cover plate.
Background technology
In the past, the fixed form of 3M adhesive tape, glue or screw was generally adopted in the fixed installation of safety hammer on railcar side top board and emergency release cover plate.In the vehicle operating process, because environment inside car and Influence of Temperature, there is the hidden danger that lost efficacy in the fixed form of 3M adhesive tape or glue; Also often there be the phenomenon of screw thread because of the wearing and tearing slippage in screw because there is the hidden danger that gets loose in factors such as vibrations, and simultaneously, does not also meet the requirement that automobile interior does not reveal bright nail, also really runs counter to the integrated beauty work efficiency of vehicle.
Summary of the invention
The purpose of this invention is to provide a kind of railcar side roof safety hammer and the solid and reliable installing and fixing method of emergency release cover plate, to solve inefficacy that the conventional fixed method exists and the problem that gets loose, simultaneously again with the perfect harmony of car body interior trim.
For realizing above-mentioned purpose, the present invention provides safety hammer and emergency release cover plate installation method on a kind of railcar side top board, it is characterized in that comprising the following steps:
1, at first perforate on cover plate and side top board, and the foul in the hole cleaned out;
2, align the position in hole on position and the vehicle side top board of cover plate surface holes;
3, with the plastic cement rivet with about, up and down direction fills in the hole successively;
4, the evagination section diameter is greater than the diameter in hole on cover plate and the side top board in the middle of the plastic cement rivet, and front end is tapered, and centre portion has a long tapered indentations;
5, firmly push all and fill in the plastic cement rivet in the hole, make cover plate consistent with side top board surface Pingdu, the plastic cement rivet is all fastening firm, seamless.
The present invention installs and fixes through using the plastic cement rivet, because the evagination section diameter is greater than the diameter in hole on cover plate and the side top board in the middle of the plastic cement rivet, front end is tapered; Than being easier to get in the hole, when external force made it slide into middle part, itself and hole wall output were pushed strongly; Plastic cement rivet centre portion has a long tapered indentations, and the plastic cement rivet is through extruding, and elastic deformation partly takes place intermediate groove; Produce a lasting expansive force; Cause the plastic cement rivet can't withdraw from the nail hole,, do not receive environment and Influence of Temperature simultaneously again even reach the effect that vibrations also can not be become flexible.
Description of drawings
Fig. 1 is the structural representation of plastic cement rivet;
Fig. 2 is the cutaway view along A-A line among Fig. 1;
Fig. 3 is the cutaway view along B-B line among Fig. 1.
The specific embodiment
Foreign material in the hole are cleaned out in the hole of 1, at first on cover plate and side top board, directly opening φ 3.75;
2, the position of cover plate surface holes is aligned the position in hole on the vehicle side top board;
3, with the plastic cement rivet with about, direction is up and down filled in the hole successively;
4, with reference to Fig. 1, plastic cement rivet centre portion is the size of φ 4, and front end is tapered, get in the hole than being easier to, but when external force forced its friction to slide into the part of φ 4, itself and hole wall output is pushed strongly; Plastic cement rivet centre portion has a long tapered indentations, and the plastic cement rivet is through extruding, and elastic deformation partly takes place intermediate groove; Produce a lasting expansive force; Cause the plastic cement rivet can't withdraw from the nail hole, even reach the effect that vibrations also can not be become flexible, locking effect is good.
5, all are filled in the plastic cement rivet in the hole, and firmly push, the plastic cement rivet is pressed into the end, guarantee that cover plate is consistent with side top board surface Pingdu, harmony with hand; Simultaneously, check that all plastic cement rivets are all fastening firm, seamless.
Unloading process: safety hammer and emergency release cover plate in case of emergency, directly smash for the cover plate of the emergency serving unit in emergency circumstances launched, just can use, so in the ordinary course of things, need not dismounting.Dismounting if desired only needs use external tool, like screwdriver etc., it is pried open, and new cover plate is installed is got final product.
