Description

Anti-pinch lifting door of dustbin

Technical Field

The utility model belongs to a waste classification retrieves intelligent equipment in the environmental protection field relates to a dustbin and prevents tong overhead door.

Background

The garbage classification is an improvement of the traditional garbage collection and disposal mode, and is a scientific management method for effectively disposing garbage. After the garbage is collected in a classified manner, classified disposal of different types of garbage is facilitated. Not only improves the utilization level of garbage resources, but also can reduce the garbage disposal quantity.

However, the throwing port door of the existing garbage classification box is turned inwards, turned back and forth, opened and closed, and is easy to clamp hands; when the garbage is fully piled up, the throwing opening door cannot be opened, and the equipment is easily damaged after the throwing opening door is forcibly opened.

There is therefore a need for improvements to existing waste bin chute doors.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Aiming at the defects of the prior art, the utility model mainly aims at providing a dustbin anti-pinch lifting door which adopts an electric up-and-down opening and closing mode and has high safety, low cost and reliable performance;

the utility model discloses a second purpose provides a dustbin prevents tong overhead door, solves current dustbin and throws a mouthful door after rubbish is filled with, throws a difficult problem that mouthful door can't be opened.

(II) technical scheme and beneficial effect

Purpose above the utility model discloses a following technical scheme realizes:

the utility model provides a dustbin pinch proof overhead door, includes main frame, door frame, slides and sets up the door plant on two guiding axles that are parallel to each other on the door frame and the electronic push-and-pull rod that drives the door plant and reciprocate along the guiding axle. The left end and the right end of the door plate are slidably mounted on the guide shaft through two linear sliding blocks respectively, the electric push-pull rod is mounted on the door plate through a first linking piece, the electric push-pull rod is fixed on the main frame through a second linking piece, and the two linear sliding blocks are located on two sides of the door plate. Prevent tong door-tongue is connected to the door plant through the linear slide rail at both ends on, travel switch installs in the door plant both sides, prevents the top of tong door-tongue.

The electric push-pull rod consists of a driving motor, a speed reducer, a sliding spiral transmission mechanism, a push rod and other main parts. The spring buffer mechanism and the overload protection device are arranged in the device, so that the safety and the reliable operation of products can be ensured. The motor drives a pair of screw nuts after being decelerated by the gear. The rotary motion of the motor is changed into linear motion, and the action of a push rod is completed by utilizing the positive and negative rotation of the motor;

the linear slide rail is used for supporting and guiding the moving component to do reciprocating linear motion in a given direction.

The linear sliding block is matched with the guide shaft for use in the linear reciprocating motion occasion, can bear certain torque, and can realize high-precision linear motion under the condition of high load.

The utility model discloses an anti-pinch door is at the in-process that closes the door, and anti-pinch door tongue touches the operator (or the operator touches and prevent pinch door tongue), prevents pinch door tongue and passes through linear slide rail rebound and trigger travel switch, and travel switch becomes normally closed state by normally open state, sends the signal that lets the reversal of electric push-pull rod motor, and electric push-pull rod motor rotates in the opposite direction to make the door plant become the ascending motion.

Has the advantages that:

the technical scheme provided by the utility model in, prevent tong door bolt through the setting, reach and prevent that the dustbin from throwing the mesh of mouthful door tong, through gliding overhead door about setting up, solve the dustbin and hold the problem that the back was thrown mouthful door and can't be opened after full.
