As an alternative embodiment, a specific embodiment of the shaft bracket 7 is further provided, the shaft bracket 7 is arranged as shown in fig. 3, a clamping hole 71 is arranged in the shaft bracket 7, and the optical axis 6 passes through the clamping hole 71 and is fastened by a bolt 72. The bottom surface of the shaft bracket 7 is fixed to the upper part of the door leaf 2. The holder 7 may fix the optical axis 6, and the specific structure is not limited thereto.
For better fixing effect, as an alternative embodiment, referring to fig. 1 to 3, the number of the shaft brackets 7 is two. Two shaft mounts 7 secure the optical axis 6 from both ends thereof.
As an alternative embodiment, with reference to fig. 1-3, the sliding block 3 is arranged between two carriages 7. Above-mentioned setting mode, pedestal 7 can also play limiting displacement to sliding block 3 except the effect of fixed optical axis 6 for sliding block 3 can only move between two pedestals 7, prevents that sliding block 3 from dislocating.
As an alternative embodiment, referring to fig. 1 and 2, a hinge rod 8 is disposed on the door frame 1, a first rotating shaft 81 is disposed at a lower portion of the hinge rod 8, and a rear end of the electric push rod 4 is rotatably connected to the hinge rod 8 through the first rotating shaft 81.
The arrangement enables the rear end of the electric push rod 4 to rotate around the first rotating shaft 81 when the door 2 is opened and closed. It should be understood that, for clarity of explanation, the front end of the electric push rod 4 refers to the end from which the push rod is pushed out, and the opposite end is the rear end of the electric push rod 4.
As an alternative embodiment, referring to fig. 1 and 2, a second rotating shaft 91 is provided at a lower portion of the sliding block 3, and a front end of the electric push rod 4 is rotatably connected to the sliding block 3 through the second rotating shaft 91. With the above arrangement, when the door leaf 2 is opened and closed, the front end of the electric push rod 4 can rotate around the second rotating shaft 91.
But the setting of second pivot 91 on first pivot 81 on the above-mentioned articulated mast 8 and the sliding block 3 can make the both ends of push rod be revolution mechanic, can carry out the free rotation, and under the opening and the closed state of the door leaf 2 of being convenient for, the instant motion of electric putter 4. It should be understood that the upper part of the sliding block 3 may be provided with a cavity structure for mounting the linear bearing and sliding linearly on the optical axis 6, and the lower part thereof may be provided with a solid structure and a through hole for mounting the second bearing, so as to realize the rotation connection of the front end of the electric push rod 4 to the lower part of the sliding block 3 through the second rotating shaft 91, which is a conventional arrangement in the art and thus not shown in the drawings.
As an alternative embodiment, in particular, the hinge rod 8 is disposed on the door frame 1, and a triangular frame structure is formed between the electric push rod 4 and the door frame 1 and the door leaf 2, so that the electric push rod 4 can perform a sector rotation when moving.
The automatic door opening structure provided in the embodiment of the utility model can be applied to the automatic vending machine and is electrically connected with the control system, and the push and retraction of the push rod can be realized by controlling the rotation direction of the stepping motor in the electric push rod through the control system; this structure action is nimble reliable, and control is simple, can be used to sell the commodity of machine by oneself and go out the storehouse, and the rice mouth of getting of the self-service rice machine of selling of specially adapted sells by oneself just using being applied to the rice mouth of selling the rice machine by oneself as an example below, does brief explanation to its specific work flow: when the rice selling machine has no transaction, the structure is in a standby state, the door is closed, when an order of the rice selling machine is generated and rice milling is finished, the control system gives an instruction to the electric push rod 4, and the push rod pushes the opening bin door; the self-service vending equipment aims at large crowds, the quality, the habit and the like are different, after the door is opened, a person needs to open the door to be larger or touch the door unintentionally, the door can continue to move at the moment, and the sliding block can move and the push rod can rotate in a fan shape, so that the integral structure is effectively protected; after the customer finishes taking the rice, the spring immediately pulls back the sliding block after the external force is eliminated, so that the whole structure is restored to a complete state; and a step motor in the electric push rod 4 is given a reverse instruction after delaying for several seconds, and the bin gate is closed.
The control system can be designed independently or in an interlocking manner with other mechanisms, and is safe and reliable. Of course, the electric push rod can be used independently without being used with a control system, and only the stepping motor in the electric push rod needs to be started. When the controller is used for controlling the stepping motor in the electric push rod, for higher safety, an infrared photoelectric switch can be arranged at the corresponding position of the door frame and the door leaf, if an M18 correlation type photoelectric switch normally-closed type can be adopted, the infrared photoelectric switch is divided into a paired emitter and receiver, the infrared photoelectric switch is electrically connected with a control circuit of the electric push rod, when the door frame and the door leaf are not shielded, the receiver can normally receive an infrared signal of the emitter, and the circuit is normally closed to work; when sheltering from between door leaf and the door frame, the infrared signal of transmitter can't be received to the receiver, and the circuit disconnection, electric putter is out of work. Above-mentioned setting can make the door leaf close the in-process, if during user or foreign matter were in door frame and door leaf, prevent that the door leaf from closing immediately, cause the potential safety hazard or damage the door leaf. It should be understood that the above-mentioned infrared photoelectric switch is mature prior art, and the wiring circuit is common knowledge in the art, and it is not repeated here, and it is applied to the automatic door opening structure of the present invention, and it is safer to use.
The automatic door opening structure has wide application range, can be used for opening and closing large doors and windows, can also be used for opening and closing small doors and windows, and only needs to select a proper push rod according to an opening and closing object.
The particular features, structures, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
