Description

Seat spring is to hole assembly and disassembly tools

Technical Field

The utility model relates to a seat appurtenance, more specifically the utility model relates to a seat spring is to hole assembly and disassembly tools.

Background

The seat spring is fixed at the lower part of the seat, and a safety belt is sleeved at the upper part of the seat spring, so that the seat cushion can be attached to the seat back under the non-use state under the action of the elastic force of the seat spring, and the seat spring is generally designed as a crew seat to realize automatic retraction. Due to the particularity of the installation position of the seat spring, difficulty exists in the assembling and disassembling process, the two valve blocks are used for jacking the spring, the spring is screwed down through screws, and the spring is compressed by utilizing the stroke of the valve blocks. But valve block horizontal stroke is limited, can't reach the installation angle of ideal to because spring compression stroke is not enough, need dismantle spring hole seat, probably still can use special wood to extrude the bedplate in addition, in order to obtain the biggest installation space, so lead to the dismouting step many, spring hole seat dismouting leads to the screw smooth silk easily, increases the dismantlement degree of difficulty. As another example, the spring mounting and dismounting tool for crew seat disclosed in CN208961933U requires a gas cylinder to inflate and push an oil chamber piston to apply pressure to a spring for mounting and dismounting the spring. Therefore, there is a need for further research and improvement in the structure of the disassembly and assembly tool for the crew seat spring.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention is a seat spring hole-aligning dismounting tool, which is designed by using the lever principle, and includes a handle body 1, an arc-shaped portion 2 is designed at the front portion of the handle body 1, the arc-shaped portion 2 and the handle body 1 can be processed by 42CRMO and other technical materials, more importantly, a guide groove 3 is designed at the free end of the arc-shaped portion 2, and the guide groove 3 is matched with the end of a seat spring 4, so that the end of the seat spring 4 can be clamped into the guide groove 3, and as shown in fig. 2, the guide groove 3 can be designed into a U shape. Meanwhile, in order to temporarily fix the tool during use, a fixing screw hole 5 is additionally arranged at the other end of the arc-shaped part 2. The fixing hole 5 is a stress point when the tool is used, so that the fixing screw hole 5 can be preferably designed at the joint between the arc-shaped part 2 and the handle body 1; and the circle center tangent of the fixing screw hole 5 is lower than the lowest point of the guide groove 3. The radian and length requirements of the fixing screw hole 5 and the arc-shaped part 2 of the tool stressed support are required to meet the requirement that the spring has a stable stress direction in the process of making about 1/4 circular arc motion around the pin. Meanwhile, the guide groove 3 and the handle body 1 have enough distance, and people cannot be hurt even if the seat spring is suddenly broken in the installation process.

As shown in the figures, the arcuate portion 2 of the assembly/disassembly tool may be machined flat to save its lateral space occupation and also to facilitate the machining of a U-shaped guide slot in the end of its free end. Meanwhile, for convenience of use, the guide groove 3 can be designed to be consistent with the radial direction of the seat spring 4, and also for reducing the space occupation of the tool body at the lower part of the seat, the maximum radian of the arc-shaped part 2 can be set to be less than 180 degrees, for example, the fixed screw hole 5 at the joint of the arc-shaped part 2 and the handle body 1 is used as a starting point, and the radian of bending to the stress point of the seat spring is 188 < the radian of the arc-shaped part < the arc of the wall. Meanwhile, the included angle between the tail end of the arc-shaped part 2 and the handle body 1 can be set randomly within the range of 0-180 degrees.

As with the construction of the tool described above in this embodiment, the seat spring 4 is an air attendant seat spring 4, and the seat spring 4 has a free end of a zigzag shape which is fitted into the guide groove 3, and in accordance with the construction described above, the arcuate portion 2 is formed to conform to the radial direction of the seat spring 4.

In this embodiment, the arc-shaped portion is designed at the front end of the handle body 1, and the guide groove 3 is designed at the front end of the arc-shaped portion 2, so that the end portion of the seat spring 4 can be radially clamped into the guide groove 3, and then the seat spring can be compressed in a lever manner, the seat spring 4 can be installed in a hole when the seat spring moves forward, and the seat spring 4 can be disassembled and assembled when the seat spring moves backward.

Referring to fig. 1 and 3, the above preferred embodiment of the present invention is to press down the seat plate of the attendant completely, the seat plate is 90 ° with the included angle of the wall, the fixing screw of the safety belt is removed, the safety belt is taken out, the arc part 2 is fixed on the fixing position of the original safety belt through the fixing screw hole 5 by the installation of the original screw, and the fixing is movable and fixed, the screw and the tool reserve the gap of 2-3mm, and the fine adjustment of the left and right sides of the time hole can be found conveniently. The end of the seat spring 4 is pushed down by a straight screwdriver so that the end of the seat spring 4 enters the U-shaped guide groove 3 at the end of the arc-shaped portion 2. Then slightly lifting the seat board, wherein the included angle between the seat board and the wall is about 70 degrees, pressing the seat board downwards and pulling the seat board outwards to separate the seat board from the seat guide groove, and obtaining the largest dismounting space. Then keep present contained angle, the left hand is pushed down the seat base board and is basically motionless this moment, and the right hand lifts handle body 1, drives arc portion 2 through handle body 1 and rotates to drive seat spring 4 and compress, can look for the hole installation seat spring 4 this moment, after aiming at spring hole seat, drive arc portion 2 through handle body 1 and push forward can. As in the above-described method of use, the seat spring 4 is removed in a reverse manner, the seat plate is pressed downwards and pulled outwards, so that the seat plate has the largest removal space from the mounting hole, the left hand presses the seat plate, and the right hand lifts the handle body 1 back to remove the seat spring 4, which is not described in detail herein. With the use method, the seat spring 4 can be disassembled and assembled by using the tool provided by the utility model, a larger disassembling and assembling space can be obtained without disassembling and assembling the spring hole seat, and the lever principle can be used for labor-saving operation.

The utility model discloses utilize the screw hole of fixed safety belt, through lever principle, can install the stable spanner of a portable arc shape and atress direction here. Finding the maximum space angle to compress the dismounting spring, so that the spring is butted with or separated from the spring hole seat.

Based on the above structure and using mode, the opening position of the tool supporting point and the bending arc of the head compression are slightly changed, so that the folding seat can be used on the same type of crew folding seats, such as aviation crew seats of different manufacturers and high-speed rail/bus crew vertical seats of similar structures.
