Description
Technical field
The present invention relates to recreational facilities technical field more particularly to a kind of recreation ground protection chairs.
Background technique
Nowadays, against people's economic level raising, already not only pursue substance on satisfaction, spirit level it is rich
Richness is also required to follow up therewith.Thus, present parents' meeting goes recreation ground to play with child, loosens mood, in recreation ground
Various amusement facilities are will be installed mostly using a kind of protection chair, after people is sitting in seat, is protected people by safe block and are present
On chair, prevent movement from throwing away people, the safe block in existing seat generally uses ratchet-type structure to carry out preventing from turning round, but
It is that clamping will appear abrasion for a long time for pawl and ratchet, until impacting the excessive spine for causing mutually to be clamped with pawl during the motion
Tooth is broken, certain angle so that safe block is opened, and as under the effects of inertia, pawl be will continue to rear
Continuous ratchet causes to wear, and the people sat on is caused to be thrown out of, and safety accident occurs.
For this purpose, it is proposed that a kind of recreation ground is solved the above problems with protection chair.
Summary of the invention
The purpose of the present invention is to solve problems of the prior art, and the anti-guard housing of a kind of recreation ground proposed
Chair.
To achieve the goals above, present invention employs following technical solutions:

Bolt is fixedly connected, and is symmetrically arranged with turn trough on the two sides side wall of the chair back, and shaft is rotatably connected in turn trough, is turned described in two
One end that axis is away from each other is equipped with safe block, and the two sides side wall of the chair back is equipped with installation cavity, and is equipped in installation cavity electronic
Telescopic rod, the output shaft of the electric telescopic rod are connected with pawl, and fixing sleeve is equipped with ratchet on the outside side wall of the shaft,
And pawl is mutually clamped with one of ratchet in ratchet, ER fluid is filled in the turn trough, and right on the side wall of turn trough
Title is set there are two opposite arc installation cavity, and capacitor board is equipped in arc installation cavity, and being equipped at the notch of the turn trough prevents
The sealing device that ER fluid overflows, the side wall of the another one ratchet in the ratchet is equipped with push switch, described
Contact is connected with by the first strut on the side side wall of pawl.
Preferably, the side wall of the ratchet is equipped with arc chute, and the side of arc chute be connected with by spring and
The sliding block that arc chute matches, the sliding block are connected with push switch, the side side wall of the ratchet by the second strut
It is upper that arc bump is connected with by telescopic rod, push rod is fixedly connected on the side side wall of second strut.
Preferably, the sealing device includes the end cover being arranged on turn trough notch, and end cover is set in and turns
On the outside side wall of axis, the end cover is fastened on the side wall of the chair back by multiple lock-screws.
Preferably, it is electrically connected between the push switch and capacitor board.
Preferably, there are multiple grooves around array on the inner wall of the turn trough.
Compared with prior art, the beneficial effects of the present invention are:
1, the present invention is used cooperatively by ER fluid, capacitor board, contact, push switch, in ratchet with pawl
Mutually the ratchet of clamping is broken, when safe block is opened, so that contact is in contact with push switch, so that two pieces
Voltage is generated between capacitor board, so that ER fluid moment becomes solid-state from liquid, so that being formed between shaft and turn trough
One entirety causes people to be thrown out of from seat so that safe block be effectively prevent to continue to open；
2, the present invention passes through the cooperation of the components such as arc chute, sliding block, telescopic rod, arc bump, push rod, so that pushing
After push rod, so that after sliding block slides in arc chute, and then push rod squeezes arc bump, so that push rod connects with arc bump
Touching, so that the stroke between push switch and contact shortens, so as to be adjusted according to the difference of adult and child's body
Section, security performance are higher.

Embodiment 1
Referring to Fig.1-7, a kind of recreation ground protection chair, including seat 1 and the chair back 2, pass through between seat 1 and the chair back 2
Multiple clamping screws are fixedly connected, and turn trough 19 are symmetrically arranged on the two sides side wall of the chair back 2, and be rotatably connected to shaft in turn trough 19
4, one end that two shafts 4 are away from each other is equipped with safe block 3, and the two sides side wall of the chair back 2 is equipped with installation cavity 5, and in installation cavity 5
Equipped with electric telescopic rod 9, the output shaft of electric telescopic rod 9 is connected with pawl 10, and fixing sleeve is equipped on the outside side wall of shaft 4
Ratchet 7, and pawl 10 is mutually clamped with one of ratchet in ratchet 7, has multiple grooves around array on the inner wall of turn trough 19,
When so that ER fluid 8 becoming solid-state from liquid, is formed and be clamped with groove, prevented shaft 4 from continuing to rotate, filled out in turn trough 19
Two opposite arc installation cavitys 20 are symmetrically arranged with filled with ER fluid 8, and on the side wall of turn trough 19, and in arc installation cavity 20
Equipped with capacitor board 21, the sealing device for preventing ER fluid 8 from overflowing is equipped at the notch of turn trough 19, sealing device includes that setting exists
End cover 6 on 19 notch of turn trough, and end cover 6 is set on the outside side wall of shaft 4, end cover 6 passes through multiple
Lock-screw is fastened on the side wall of the chair back 2, prevents ER fluid 8 from overflowing from turn trough 19, the another one spine in ratchet 7
The side wall of tooth be equipped with push switch 12, be electrically connected between push switch 12 and capacitor board 21 so that contact 11 with press
When 12 phase of pusher-type switch squeezes, circuit is switched on, and is connected with contact 11 by the first strut on the side side wall of pawl 10.
In the present invention, after prolonged use with protection chair, pawl 10 mutually blocks the recreation ground with the ratchet in ratchet 7
It connects, under the action of continuous abrasion and impact, the ratchet being mutually clamped will appear fracture, and in fracture, safe block 3 can be beaten
It opens, then ratchet 7 is driven to turn an angle, then the push type on the ratchet adjacent with fracture ratchet of the contact 11 on pawl 10 is opened
It closes 12 to be in contact, push switch 12 is pressed rear circuit conducting, then voltage is generated between two pieces of capacitor boards 21, in the work of voltage
Under, due to the Wen Saige phenomenon of ER fluid 8: under the action of electric field force, the viscosity of ER fluid 8 can increase in moment
Several orders of magnitude so that the transformation of liquid-solid can occur for ER fluid 8, and transformation be it is mutually reversible, then make
Shaft 4 and turn trough 19 form an entirety, to prevent safe block 3 from continuing to open, the personnel sat on the seat are caused to be got rid of
Out, danger is in turn resulted in.
