Abstract
The utility model discloses a piston spring formula anticollision door, characterized by: including wall body, door -hinge, door, spring, door frame, piston cylinder, piston and piston rod, the door relies on the door -hinge to install on the wall body, the door top relies on the spring coupling door frame, the piston cylinder articulates on the wall body, the piston cylinder bottom is equipped with check valve first, and the piston cylinder top is equipped with the gas pocket, and the piston with the coaxial transition fit of piston cylinder inner wall is connected to piston rod one end, and the piston rod other end articulates in the door back, is equipped with on the piston than the first little check valve second of discharge of fumes and gas on the check valve. The beneficial effect of the utility model as follows: utilize that acting force of spring is automatic to close the door, with the help of the impact that door and door frame are slowed down to piston inside negative pressure, convenient and practical has higher spreading value.
Description
Technical field
This utility model relates to a kind of anticollision door, particularly to a kind of piston spring formula anticollision door.
Background technology
The most many room doors are provided with self closing device, are automatically switched off after room door is opened.Traditional rooms door is automatically switched off dependence elastic force effect, and acceleration is big, and door and doorframe easily clash into, and produces noise, shortens the life-span of door.This utility model one piston spring formula anticollision door, utilizes acting force of the spring automatic door-closing, slows down the impact force of door and doorframe by internal piston negative pressure, convenient and practical, has higher promotional value.
Summary of the invention
The purpose of this utility model is aiming at the deficiency that prior art exists, it is provided that a kind of piston spring formula anticollision door, utilizes acting force of the spring automatic door-closing, slows down the impact force of door and doorframe by internal piston negative pressure, convenient and practical, has higher promotional value.
A kind of piston spring formula anticollision door, it is characterized in that: include body of wall, door-hinge, door, spring, doorframe, piston cylinder, piston and piston rod, described door relies on door-hinge to be arranged on body of wall, described header relies on spring to connect doorframe, described piston cylinder is hinged on body of wall, check valve first it is provided with bottom described piston cylinder, piston cylinder top is provided with pore, piston rod one end connects the piston coordinated with piston cylinder inwall coaxial transition, the piston rod other end is hinged on face behind the door, and piston is provided with the check valve second less than check valve first capacity.
During enabling, spring elongation put aside energy under external force, door relies on piston rod to promote piston rearward movement in piston cylinder simultaneously, and the check valve first on piston cylinder is opened, and piston cylinder internal gas is discharged；It is automatically switched off in spring force effect Xiamen, door relies on piston rod to pull piston at piston cylinder move forward inside, check valve second on piston is opened, and owing to check valve second steam vent is smaller, is in negative pressure state inside piston cylinder, force balance spring force on piston rod, reducing door and the impact force of doorframe, final gas is slowly entered inside piston cylinder by check valve second, and piston cylinder air pressure inside is Jun Heng with external pressure, negative pressure disappears, and spring force also disappears.
Accompanying drawing explanation
Accompanying drawing 1 is overall structure schematic diagram of the present utility model.
In upper figure: body of wall 1, door-hinge 2, door 3, spring 4, doorframe 5, piston cylinder 6, check valve first 6.1, pore 6.2, piston 7, check valve second 7.1, piston rod 8.
Detailed description of the invention
In conjunction with accompanying drawing 1, this utility model is further described:
As shown in Figure 1, this utility model includes body of wall 1, door-hinge 2, door 3, spring 4, doorframe 5, piston cylinder 6, piston 7 and piston rod 8, described door 3 relies on door-hinge 2 to be arranged on body of wall 1, described door 3 top relies on spring 4 to connect doorframe 5, described piston cylinder 6 is hinged on body of wall 1, it is provided with check valve first 6.1 bottom described piston cylinder 6, piston cylinder 6 top is provided with pore 6.2, piston rod 8 one end connects the piston 7 coordinated with piston cylinder 6 inwall coaxial transition, piston rod 8 other end is hinged on after door 3, and piston 7 is provided with the check valve second 7.1 less than check valve first 6.1 capacity.
Open the door 3 time, spring 4 stretches and puts aside energy under external force, and door 3 relies on piston rod 8 to promote piston 7 rearward movement in piston cylinder 6 simultaneously, and the check valve first 6.1 on piston cylinder 6 is opened, piston cylinder 6 internal gas discharge；It is automatically switched off in spring 4 elastic force effect Xiamen 3, door 3 relies on piston rod 8 to pull piston 7 at piston cylinder 6 move forward inside, check valve second 7.1 on piston 7 is opened, owing to check valve second 7.1 steam vent is smaller, piston cylinder 6 is internal is in negative pressure state, force balance spring 4 elastic force on piston rod 8, reduce door 3 and the impact force of doorframe 5, it is internal that final gas is slowly entered piston cylinder 6 by check valve second 7.1, piston cylinder 6 air pressure inside is Jun Heng with external pressure, negative pressure disappears, and spring 4 elastic force also disappears.
The invention has the beneficial effects as follows: utilize acting force of the spring automatic door-closing, slow down the impact force of door and doorframe by internal piston negative pressure, convenient and practical, there is higher promotional value.
