Abstract
The utility model provides a rope-pulling-type safety switch of a reel machine of a greenhouse. A fixed board is connected with a side of a frame. A fixing hole is arranged in the fixed board. A switch device is installed on a switch shaft between the frame and the fixed board. A convex-concave table is arranged on the switch device. Contacts are installed on a side of the convex-concave table through a contact shaft. The contacts are arranged on two sides of the switch device oppositely, thereby forming the connection and the disconnection of a circuit. A ratchet wheel is installed on the switch shaft in the center of a rope-pulling board on a side of the switch shaft. A spring is installed between a junction position of the rope-pulling board and wheel teeth of the ratchet wheel and the frame. A pawl is installed between the rope-pulling board and the wheel teeth of the ratchet wheel. Two ends of the rope-pulling board are provided with rope-fastening holes respectively. Pulling ropes are fastened in the rope-fastening holes. According to the utility model, since the switching of the rope-pulling-type safety switch of the reel machine of the greenhouse can be realized through pulling the ropes, a motor of the reel machine can be switched off conveniently to stop the rotation of the motor when a human body is coiled by the ropes, thereby preventing the occurrence of safety accidents. The rope-pulling-type safety switch of the reel machine of the greenhouse is suitable for installing on and using for the reel machine of the greenhouse.
Description
Technical field
The utility model provides the switch of appliance field, specifically greenhouse roller cord pulling type safety switch.
Background technology
Key in herein background technology and describe paragraph.The switch that the existing useful remote controller of greenhouse roller state of emergency switch carries out remote control, existent defect is: when the generation human body was lived by shutter rope volume, the person was limited, causes operating, and caused human body to be rolled up and damage or death.
Summary of the invention
In order to overcome the shortcoming of existing remote control switch, the utility model provides greenhouse roller cord pulling type safety switch.This switch opens and closes by stay cord handle and ratchet driving switch, solves the technical problem that greenhouse roller switch rope draws shake-up.
The scheme that the utility model technical solution problem adopts is:
Framework one side is connected with fixed head, is provided with fixing hole at fixed head; Switch shaft between framework and fixed head is equipped with derailing switch, and derailing switch is provided with the convex-concave platform, by the contact axle contact is installed in convex-concave platform one side, and the contact is oppositely arranged on the both sides of derailing switch, forms contact or the disconnection of circuit; Switch shaft in the middle of the stay cord plate of switch shaft one side is equipped with ratchet, between stay cord plate and ratchet gear teeth junction and framework spring is installed, and between stay cord plate and the ratchet gear teeth ratchet is installed; Stay cord plate two ends are respectively equipped with rope hole, and bolt has stay cord in rope hole.
Good effect because the utility model draws the keying that can realize switch by rope, is restricted volume when living when human body occurs, and is convenient to turn-off the shutter motor, makes it to stop the rotation, thereby prevents the generation of security incident.Suitable to installing and using on the greenhouse curtain-rolling machine.
Description of drawings
Fig. 1 is the utility model structure chart
Fig. 2 is the utility model plan structure figure
Fig. 3 is the utility model derailing switch movement state diagram
Among the figure, 1. framework, 2. stay cord plate, 3. stay cord bar spring, 4. ratchet, 5. switch shaft, 6. rope hole, 7. stay cord, 8. fixed head, 9. fixing hole, 10. derailing switch, 11. contact axles, 12. contacts.
Embodiment
According to the figure, framework 1 one sides are connected with fixed head 8, are provided with fixing hole 9 at fixed head;
Switch shaft 5 between framework and fixed head is equipped with derailing switch 10, and derailing switch is provided with the convex-concave platform, by contact axle 11 contact 12 is installed in convex-concave platform one side, and the contact is oppositely arranged on the both sides of derailing switch, forms contact or the disconnection of circuit;
Switch shaft in the middle of the stay cord plate 2 of switch shaft one side is equipped with ratchet 4, between stay cord plate and ratchet gear teeth junction and framework spring 3 is installed, and between stay cord plate and the ratchet gear teeth ratchet is installed;
Stay cord plate two ends are respectively equipped with rope hole 6, and bolt has stay cord 7 in rope hole.
When pulling stay cord plate, the stay cord plate drives derailing switch by switch shaft and rotates, and produces moment, makes relative two contactings or disconnection, when stopping drag the stay cord plate, is subjected to the active force of spring, stay cord plate self-return, thereby the connecting and disconnecting of realization switch.
Installation and use of the present utility model:
Install: fixed head of the present utility model is bolted on the shutter, and stay cord elongates and is fixed on the pillar of curtain rolling shaft, and stay cord is in the bottom of curtain rolling shaft.
Use: when because operate miss, when causing human body parts to be twisted on curtain rolling shaft by sectional overhead rope, touch stay cord by staff, pin or other position, the then stressed rotation of stay cord plate, produce moment, the derailing switch contact is disconnected, stop shutter and remain in operation, thereby prevent human body to be rolled into fully in the sectional overhead rope and cause the cracked and injures and deaths of limbs.
Because stay cord is applied in the below of whole curtain rolling shaft, therefore no matter any position can both make shutter start or close down, simple and fast.
The utility model suits to be used for opening and closing at the shutter of warmhouse booth the switch application of shutter.
