Abstract
The utility model discloses a reverse air spring buffer that stability is good, intensity is high. The technical scheme adopted comprises the following steps: casing, fixed mounting in air spring, slidable in the casing install in the activity in the casing is detained, the activity is detained the middle and is equipped with rotatable connecting axle, the piston rod of air spring passes the activity detain the fluting of front end with the connecting axle is connected, just the both sides of connecting axle be equipped with shells inner wall's first guide block of guide way sliding fit. Has the advantages that: the connecting shaft in the middle of the movable buckle is connected with the piston rod of the air spring, and the connecting shaft is in sliding fit with the guide grooves in the shell through the guide blocks on the two sides, so that the stability and the strength of the joint of the movable buckle and the piston rod are better.
Description
Technical Field
The utility model relates to a move a buffer.
Background
The sliding door buffer is mainly applied to household sliding doors, shower rooms and other products, and solves the safety problem that the sliding door can make 'bang' or clamp hands due to inertia pushing impact caused by too smooth pulleys. After the buffer is arranged on the sliding door, the sliding door can automatically buffer when the sliding door is about to reach the side plate, so that the sliding door can be slowly closed, and the sliding door is prevented from rebounding. Conventional reverse gas spring damper constructions, such as: the chinese utility model patent with the granted announcement number of "CN 204754555U" and the name of "hanging wheel moves a buffer" shows that the structure includes: the shell, the air spring fixedly installed in the shell and the movable buckle slidably installed in the shell, wherein a piston rod of the movable buckle is hinged to the end of the movable buckle through a rotating shaft. There are disadvantages in that: the joint of the piston rod and the movable buckle has poor strength and stability, and the movable buckle is easy to break after being violently impacted by the trigger and generates great noise.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a reverse air spring buffer that stability is good, intensity is high.
In order to solve the above problem, the utility model discloses a technical scheme include: casing, fixed mounting in air spring, slidable in the casing install in activity in the casing is detained its characterized in that: the middle of the movable buckle is provided with a rotatable connecting shaft, a piston rod of the air spring penetrates through the groove at the front end of the movable buckle and is connected with the connecting shaft, and the two sides of the connecting shaft are provided with first guide blocks in sliding fit with the guide grooves in the inner wall of the shell.
The reverse gas spring buffer is characterized in that: and a second guide block is arranged on the movable buckle.
The reverse gas spring buffer is characterized in that: the piston rod is in threaded connection with the connecting shaft.
The reverse gas spring buffer is characterized in that: the first guide block is rectangular.
The reverse gas spring buffer is characterized in that: the second guide block is cylindrical.
The reverse gas spring buffer is characterized in that: the side wall of the piston rod is attached to the side wall of the groove.
The utility model discloses a reverse air spring buffer's beneficial effect: the connecting shaft in the middle of the movable buckle is connected with the piston rod of the air spring, and the connecting shaft is in sliding fit with the guide blocks on the two sides of the connecting shaft and the guide grooves in the shell, so that the stability and the strength of the joint of the movable buckle and the piston rod are better, the movable buckle can be effectively prevented from being broken and the noise is low.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
FIG. 1 is an exploded view of the reverse gas spring damper of the present invention;
FIG. 2 is a schematic structural view of the movable buckle of the present invention;
fig. 3 is an exploded view of the movable buckle of the present invention.
Detailed Description
As shown in fig. 1 to 3, the reverse gas spring buffer of the present invention comprises a housing 1, a gas spring 2 fixedly installed in the housing 1, and a movable buckle 3 slidably installed in the housing 1. The shell 1 is formed by butting an upper shell and a lower shell and is fixed by a screw 13. The gas spring 2 is fixedly installed in the gas spring installation groove 10 of the housing 1. The movable buckle 3 is slidably installed in the guide groove 7 of the housing 1, and the striking part 11 at the upper end extends out of the housing 1 to be matched with the sliding door stopper. The middle of the movable buckle 3 is provided with a rotatable connecting shaft 4, the side wall of the connecting shaft 4 is provided with a screw hole 12, and a piston rod 5 of the gas spring 2 penetrates through a slot 6 at the front end of the movable buckle 3 to be in threaded connection with the screw hole 12 of the connecting shaft 4. And both sides of the connecting shaft 4 are provided with first guide blocks 8 which are in sliding fit with the guide grooves 7 on the inner wall of the shell 1.
Preferentially, the movable buckle 3 is provided with a second guide block 9, and the second guide block 9 is also in sliding fit with the guide groove 7, so as to further improve the sliding stability of the movable buckle 3.
Preferably, the first guide block 8 is rectangular and has a height adapted to the guide slot 7, so as to further improve the sliding stability of the movable buckle 3.
Preferably, the second guide block 9 is cylindrical to facilitate the redirection of the first guide block 8.
Preferentially, the side wall of the piston rod 5 is attached to the side wall of the slot 6, so that the connection stability between the piston rod 5 and the movable buckle 3 is further improved.
The above description is only for the preferred embodiment of the present invention and should not be construed as limiting the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention are all included within the protection scope of the present invention.
