Abstract

A pedal opening device for a closed trash can is composed of a pedal lever (1), a connecting rod (2), an annular transmission bar (3) and a lid connecting rod. One end of the pedal lever (1) is hinged to a pivot (8) on the bottom of the can body through a shaft, a returning spring (6) is hung on the pedal lever (1) near the pedal, with the other end provided on the can body. T, the pedal lever is hinged at one position to one end of the connecting rod (2) through a shaft and the other end of the connecting rod is hinged to one end of the annular transmission bar (3) through a shaft. T, the annular transmission bar (3) can pivot on a fixed shaft, and the other end of the former is hinged to one side of the can lid through a shaft. Then, according to the lever principle, when the pedal lever is stepped by a foot, the annular transmission bar will undraw the lid; when the foot leaves the pedal, the lid will close automatically under the action of the returning spring. The device has the advantages of simple structure, convenience to use and durability.

Description

Closed trash can foot switch device

The utility model relates to a closed garbage box foot switch device. Background technique

At present, the garbage bins widely used in public places such as streets, communities, parks, etc. are usually open-type garbage bins without a cover, so that odors are emitted and flies are attracted, and wind and rain may cause garbage to scatter and pollute the environment. Some covered bins need to be opened by hand to empty the trash can, so that some people will not be willing to touch the bin cover and throw the garbage out of the bin, which seriously affects the environment. Moreover, the garbage bin can spread various bacteria and germs to people's hands when the hand is opened, which increases the way of disease transmission and threatens people's health. Summary of the invention

In view of the above problems in the prior art, the object of the present invention is to provide a new type of closed garbage box foot switch device, which provides a kind of prevention of various bacteria and germs from being transmitted by human hands, thereby avoiding people's body. Health is inflicted and effectively prevents rainwater from entering. The device is simple in structure, convenient to use, and durable.

The purpose of the utility model is achieved by the following technical solutions: The structure of the closed garbage box foot switch device of the utility model is composed of a foot rod, a connecting rod, an annular transmission rod and a box cover connecting rod, the foot One end of the pedal is hinged to the bottom pivot of the box through the shaft, and a return spring is hung near the pedal. The other end of the return spring is disposed on the box, and the pedal is hinged at one end of the shaft and the connecting rod. The other end of the ring is hinged to one end of the annular transmission rod, the annular transmission rod can be driven around the fixed shaft, and the other end of the annular transmission rod is hinged to one side of the cover by the shaft. In this way, with the principle of lever, with the foot pedal, the ring drive lever pulls the cover open; when the foot leaves the pedal, the cover will automatically close under the action of the return spring.

The foot switch device is located on the same axis, on one side of the trash can, and placed in the garbage can. The plurality of foot switch devices described can be provided according to the needs of the garbage bin classification.

It can be seen from the technical solution provided by the above-mentioned utility model that the realization of the utility model makes it possible to conveniently put the garbage into the garbage bin without touching the garbage bin cover by hand, thereby ensuring people's health. Protected from infringement, it can also effectively prevent people from discarding garbage outside the bin. Environmental sanitation. The utility model has the advantages of simple structure, only need to be fixed on the box body, and can be integrated with the garbage bin, and utilizes the principle of lever, convenient use and durability. BRIEF abstract

Specific features and properties of the present invention are further exemplified by the following examples and the accompanying drawings.

Figure 1 is a specific embodiment of the present invention;

Figure 2 is a perspective view of the specific implementation of the present invention. BEST MODE FOR CARRYING OUT THE INVENTION

The utility model provides a closed garbage box foot switch device structure comprising a foot rod (1), a connecting rod (2), an annular transmission rod (3) and a box cover (5) connecting rod, the foot One end of the pedal is hinged to the bottom support point (8) of the box through the shaft, and a return spring (6) is attached to the pedal near the pedal, and the other end of the return spring (6) is disposed on the box, and the pedal rod is located at one point (7) ) The shaft is hinged to one end of the connecting rod (2), the other end of the connecting rod (2) is hinged to one end of the annular transmission rod (3) through the shaft, and the annular transmission rod (3) can be wound around the fixed shaft

(4) For the fulcrum drive, the other end of the ring drive rod (3) is hinged to one side of the cover (5) through the shaft, and the ring drive rod is slightly larger than the shaft hole hinged to the cover, and the pin is smaller. The track of the transmission rod and the cover hinged together will be longer, and the actual adjustment will be easier. In this way, using the principle of leverage, using the foot pedal

(1) Connecting the connecting rod (2) down (3) Pulling the ring drive rod (3) to pull the cover (5) apart; the foot leaves the foot lever (1), and the connecting rod (2) under the action of the return spring (6) Move up, drive the ring drive lever (3) to cover

(5) Automatically closed.

The foot switch device described in the utility model is on the same axis, so that the force is relatively uniform during the transmission process of the switch waste bin cover, thereby prolonging the service life, and the switch action is accurate and reliable. The above is only one embodiment of the present invention, and any equivalent transformation based on the present invention (see FIG. 2 and the like) is within the protection scope of the present invention.
