Description
Technical field
The utility model is related to rolling screen door technical field, more particularly to a kind of rolling screen door braking protection device.
Background technology
Electric rolling door is used widely in places such as StoreFront, garage, markets, and electric rolling door is usually by door roller
Spool is driven to rotate by transmission mechanism, the reel outside spool is rotated with spool, drive is wrapped on reel
Door curtain guide rail of the door curtain along door opening both sides slides up and down to realize switch gate.It is furnished with brake gear, existing volume in door roller
Door machine brake gear is main by brake disc, brake block, brake spring and electromagnet（Brake magnet coil）Composition, door roller work
When, electromagnet, which is powered, attracts brake block, separates brake block and brake disc and opens brake system；When door roller brakes, electromagnet
Dead electricity, brake spring promotes brake block extruding brake disc to be braked.Brake disc is general by disk body, bonding thermal insulation layer and friction material
The bed of material is constituted, and existing brake disc is after use after a while, and bonding thermal insulation layer and friction material layer are often from disk body
On come off, make drag friction power inadequate；Secondly as the fatigue of brake spring, can also make the pressure between brake disc and brake block
Power is inadequate.Above-mentioned factor can cause the brake weight of brake gear not enough, rolling screen door is slipped under being produced after brake due to deadweight, deposit
In potential safety hazard.
Utility model content
The utility model overcomes the deficiencies in the prior art and can failed or brake in door roller brake gear there is provided one kind
When power is inadequate, the rolling screen door braking protection device for preventing rolling screen door from down sliding.
The utility model is achieved through the following technical solutions：
A kind of rolling screen door braking protection device, including rectangle support plate, ratchet, ratchet, push-rod guide base, electromagnet, push away
Bar, spring and controller；The supporting plate is fixedly installed on the wall of door opening side, and its four corners are provided with mounting hole；Institute
Ratchet sleeve is stated on the spool of rolling screen door and is fixedly connected with spool；The ratchet is located at the side of ratchet, its pawl point ejection spine
The ratchet root of wheel；The push-rod guide base is fixedly arranged on the supporting plate at the upper side of ratchet；The electromagnet is fixedly arranged on push rod
On supporting plate above guide holder, the electromagnet and controller electrical connection；The push rod is oriented to through push-rod guide base and push rod
Seat is slidably connected, the base portion connection of its one end and ratchet, the other end and electromagnet armature connection；The spring housing is outside push rod
Face, its one end ejection push-rod guide base, the base portion of other end ejection ratchet.
When switching rolling screen door, controller connects solenoid circuit, and electromagnet energized action attracts push rod band pawl to overcome
The thrust of spring leaves ratchet, be arranged on ratchet on spool can normal rotation, door roller drives spool to rotate and carries out switch gate,
When rolling screen door switch gate in place after, door roller shuts down and braked, controller disconnect solenoid circuit, electromagnet dead electricity, bullet
Spring promotes push rod and ratchet to move downward, and the sharp ejection of pawl of ratchet prevents pawl wheel, so as to prevent in the ratchet root of ratchet
Spool is rotated, and in the brake gear failure of door roller or inadequate brake force, can prevent rolling screen door from down sliding.
Further, the mounting hole is bar shaped, and is laterally set.Be conveniently adjusted supporting plate is transversely mounted position.
The beneficial effects of the utility model are：Ratchet is set on spool, spine is driven using electromagnet, push rod and spring
Pawl, can prevent spool from rotating after door roller is stopped, and in the failure of door roller brake gear or inadequate brake force, make roller shutter
Door will not down slide.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection domain of the present utility model apparent clear and definite
Define.
As shown in figure 1, embodiment of the present utility model, a kind of rolling screen door braking protection device, including rectangle support plate 1,
Ratchet 2, ratchet 3, push-rod guide base 4, electromagnet 5, push rod 6, spring 7 and controller（It is not drawn into figure）；The supporting plate 1 is consolidated
On wall of the Dingan County loaded on door opening side, its four corners are provided with the bar shaped mounting hole 8 laterally set；The ratchet 2 is enclosed on volume
It is fixedly connected on the spool 9 of curtain door and with spool 9；The ratchet 3 is located at the side of ratchet 2, the ratchet of its pawl point ejection ratchet 2
10 roots；The push-rod guide base 4 is fixedly arranged on the supporting plate 1 of the upper side of ratchet 2；The electromagnet 5 is fixedly arranged on push rod and led
To on the supporting plate 1 of the top of seat 4, the electromagnet 5 and controller electrical connection；The push rod 6 is led through push-rod guide base 4 and push rod
It is slidably connected to seat 4, the base portion connection of its one end and ratchet 3, the armature connection of the other end and electromagnet 5；The spring 7 is enclosed on
The outside of push rod 6, its one end ejection push-rod guide base 4, the base portion of other end ejection ratchet 3.
When switching rolling screen door, controller connects the circuit of electromagnet 5, and the energized action of electromagnet 5 attracts push rod 6 with pawl 3
Overcome the thrust of spring 7 to leave ratchet 10, be arranged on ratchet 2 on spool 9 can normal rotation, door roller drives spool 9 to rotate
Carry out switch gate, when rolling screen door switch gate in place after, door roller shuts down and braked, controller disconnect the circuit of electromagnet 5, electricity
The dead electricity of magnet 5, spring 7 promotes push rod 6 and ratchet 3 to move downward, and the sharp ejection of pawl of ratchet 3 is prevented in the root of ratchet 10 of ratchet 2
Only ratchet 2 is rotated, so as to prevent spool 9 from rotating, in the brake gear failure of door roller or inadequate brake force, can prevent roller shutter
Door down slides.
It is described above, embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement expected without creative work should all be covered within protection domain of the present utility model.
Therefore, protection domain of the present utility model should be determined by the scope of protection defined in the claims.
