Description

Technical Field

[0001] The utility model relates to the field of garbage room accessories, in particular to an electric push rod door opening mechanism for a garbage room. Background Art

[0002] At present, garbage rooms are generally equipped with electric lifting doors. The structure of the electric lifting doors commonly used in garbage rooms is roughly as shown in the patent publication document CN219034458U. The lifting door of this structure relies on winding or releasing the wire rope to open and close the door. There is a problem in using this method of opening and closing the door by winding or releasing the wire rope, that is, once the wire rope is attached and entangled with film-like dirt (such as plastic bags) during the winding or releasing process, the wire rope is very likely to get stuck during the winding or releasing process, causing the entire electric lifting door to be unable to operate. Utility Model Content

[0003] In view of the above problems, the utility model provides an electric push rod door opening mechanism for a garbage room.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A garbage room electric push rod door opening mechanism comprises a first frame, a second frame, an electric push rod, a first baffle and a second baffle, wherein the first frame is provided with a guide rail, the second frame is provided with a guide wheel, the guide wheel on the second frame cooperates with the guide rail on the first frame, one end of the electric push rod cooperates with the first frame, and the other end of the electric push rod cooperates with the second frame, the first baffle is provided on the first frame, the second baffle is provided on the second frame, a notch is provided on the first baffle, and the second frame and the second baffle are used to cover the notch.

[0006] In this structure, the second frame can move on the first frame, and with the help of the guide rail and the guide wheel, the second frame can move stably on the first frame. The second frame moves on the first frame with the help of the electric push rod, which is equivalent to a steel wire rope. The electric push rod is not easily covered and entangled by film-like dirt during operation. The electric push rod is more stable and reliable during operation, ensuring the reliability of the entire door opening mechanism.

[0007] Optionally, it also includes a gas spring and a connecting frame, one end of the gas spring is engaged with the second frame through a pin shaft, and the other end of the gas spring is engaged with the connecting frame through a pin shaft, one end of the electric push rod is engaged with the first frame, and the other end of the electric push rod is engaged with the connecting frame through a pin shaft, two parallel guide clamps are provided on the second frame, and the connecting frame is located between the two guide clamps, each guide clamp is provided with a slide, and the two ends of the pin shaft on the connecting frame are respectively slidably engaged with the slides on the two guide clamps.

[0008] Specifically in this door opening mechanism, the electric push rod does not directly support the second frame (and the second baffle), but indirectly supports the second frame (and the second baffle) with the help of a gas spring, and the elastic force of the gas spring in a natural state is greater than the weight of the second frame plus the second baffle.

[0009] The two parallel guide clips are used to guide the connection frame to move, and the existence of the two guide clips can increase the strength of the second baffle.

[0010] In this mechanism, pin holes are provided on the electric push rod, the connecting frame and the gas spring, and the pin shaft is plugged into and matched with the pin holes on the electric push rod, the connecting frame and the gas spring, so that the pin shaft installs the electric push rod and the gas spring on the connecting frame, so that the connecting frame can slide a certain distance between the two guide clips, and when the pin shaft on the connecting frame slides to the two extreme positions of the slideway and contacts, the connecting frame no longer slides between the two guide clips.

[0011] When this mechanism is working, when the user's (or other person's) hand is in the gap and the electric push rod is closing the door, if the user's hand contacts the second frame, the hand can apply force to the electric push rod on the second frame, and the gas spring contracts (the second frame moves toward the electric push rod, and the pin shaft on the connecting frame slides in the slideway), thereby preventing the user's hand from being pinched by the second frame and the first baffle.

[0012] Optionally, the slide is a waist-shaped slide.

[0013] The function of the slide is to limit the movement of the pin shaft. The waist-shaped slide can ensure that the pin shaft slides stably in the slide.

[0014] Optionally, the guide wheel includes a first rotating guide wheel and a second rotating guide wheel, the first rotating guide wheel and the second rotating guide wheel are both installed on the second frame, and the rotation direction of the first rotating guide wheel is perpendicular to the rotation direction of the second rotating guide wheel.

[0015] The first rotating guide wheel and the second rotating guide wheel are arranged to contact the wall of the guide rail in two directions, so that compared with contact in a single direction, contact with the wall of the guide rail in two directions can improve the stability of the second frame when sliding on the first frame.

[0016] Optionally, a face camera and a status indicator light are provided on the first baffle.

[0017] The function of the status indicator light is to display the door open or closed status, while the function of the face camera is to detect whether someone is approaching.

[0018] Optionally, a position signal sensing switch is provided on the first frame, and a trigger plate is provided on the second frame.

[0019] Optionally, the first frame is a rectangular first frame.

[0020] Optionally, the second frame is a rectangular second frame.

[0021] The beneficial effects of the utility model are as follows: with the help of the guiding effect of the guide rail and the guide wheel, the second frame can stably move on the first frame, the electric push rod is stable and reliable during operation, and the reliability of the entire door opening mechanism is ensured.

DETAILED DESCRIPTION

[0028] The utility model is described in detail below in conjunction with the accompanying drawings.

[0029] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5As shown, a garbage room electric push rod door opening mechanism includes a first frame 5, a second frame 6, an electric push rod 9, a first baffle and a second baffle. The first frame 5 is provided with a guide rail 8, the second frame 6 is provided with a guide wheel, the guide wheel on the second frame 6 cooperates with the guide rail 8 on the first frame 5, one end of the electric push rod 9 cooperates with the first frame 5, and the other end of the electric push rod 9 cooperates with the second frame 6. The first baffle is provided on the first frame 5, and the second baffle is provided on the second frame 6. A notch 401 is provided on the first baffle, and the second frame 6 and the second baffle are used to cover the notch 401.

[0030] In this structure, the second frame 6 can move on the first frame 5. With the help of the guide rail 8 and the guide wheel, the second frame 6 can stably move on the first frame 5. The second frame 6 moves on the first frame 5 with the help of the electric push rod 9. Compared with the steel wire rope, the electric push rod 9 is not easy to be covered and entangled by film-like dirt during operation. The electric push rod 9 is more stable and reliable during operation, ensuring the reliability of the entire door opening mechanism.

[0031] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, it also includes a gas spring 10 and a connecting frame 12. One end of the gas spring 10 is matched with the second frame 6 through a pin shaft, and the other end of the gas spring 10 is matched with the connecting frame 12 through a pin shaft. One end of the electric push rod is matched with the first frame 5, and the other end of the electric push rod is matched with the connecting frame 12 through a pin shaft. Two parallel guide clips 11 are provided on the second frame 6, and the connecting frame 12 is located between the two guide clips 11. Each guide clip 11 is provided with a slideway 1101, and the two ends of the pin shaft on the connecting frame 12 are respectively slidably matched with the slideways 1101 on the two guide clips 11. In order to clearly show the structure of the connecting frame 12, the attached Figure 3 The pin on the connecting frame 12 is hidden, so Figure 3 The pin is not visible.

[0032] Specifically in this door opening mechanism, the electric push rod 9 does not directly support the second frame 6 (and the second baffle), and the electric push rod 9 indirectly supports the second frame 6 (and the second baffle) with the help of the gas spring 10. The elastic force of the gas spring 10 in the natural state is slightly greater than the weight of the second frame 6 plus the second baffle. When external force presses on the second frame 6, the gas spring 10 will contract.

[0033] The two parallel guide clips 11 are used to guide the connection frame 12 to move, and the existence of the two guide clips 11 can increase the strength of the second baffle.

[0034] In this mechanism, pin holes 13 are provided on the electric push rod 9, the connecting frame 12 and the gas spring 10, and the pin shaft is plugged into and matched with the pin holes 13 on the electric push rod 9, the connecting frame 12 and the gas spring 10, so that the pin shaft installs the electric push rod 9 and the gas spring 10 on the connecting frame 12, so that the connecting frame 12 can slide a distance between the two guide clips 11, and when the pin shaft on the connecting frame 12 slides to the two extreme positions of the slide 1101 and contacts, the connecting frame 12 no longer slides between the two guide clips 11.

[0035] When this mechanism is working, when the user's (or other person's) hand is in the notch 401, when the electric push rod 9 is closing the door, if the user's hand is in contact with the second frame 6, the hand can apply force to the electric push rod 9 on the second frame 6. At this time, the gas spring 10 contracts (the second frame 6 moves toward the electric push rod 9, and the pin shaft on the connecting frame 12 slides in the slide 1101), preventing the user's hand from being pinched by the second frame 6 and the first baffle.

[0036] Combined with Figure 3 As shown in , the arrangement of the guide clip, the connecting frame and the gas spring actually realizes the elastic installation of the second frame, so that the second frame has a certain buffering performance during the lifting movement.

[0037] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, the slideway 1101 is a waist-shaped slideway 1101.

[0038] The function of the slideway 1101 is to limit the movement of the pin shaft. The waist-shaped slideway 1101 can ensure that the pin shaft slides stably in the slideway 1101.

[0039] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, the guide wheel includes a first rotating guide wheel and a second rotating guide wheel, both of which are mounted on the second frame 6, and the rotation direction of the first rotating guide wheel is perpendicular to the rotation direction of the second rotating guide wheel.

[0040] The first rotating guide wheel and the second rotating guide wheel are arranged to contact the wall of the guide rail 8 in two directions. Compared with contact in a single direction, contact with the wall of the guide rail 8 in two directions can improve the stability of the second frame 6 when sliding on the first frame 5.

[0041] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, a face camera 2 and a status indicator light 1 are arranged on the first baffle.

[0042] The function of the status indicator light 1 is to display the door opening and closing status, while the function of the face camera 2 is to detect whether someone is approaching.

[0043] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, a position signal sensing switch 14 is disposed on the first frame 5 , and a trigger plate is disposed on the second frame 6 .

[0044] The specific function of the trigger plate is to trigger the position signal sensing switch 14. When the trigger plate triggers the position signal sensing switch 14, it means that the second frame 6 has moved to the extreme position, and the second frame 6 (and the second baffle plate) completely covers the notch 401 on the first baffle plate. The door is closed successfully. At this time, the electric push rod needs to stop the telescopic operation.

[0045] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, the first frame 5 is a rectangular first frame 5 .

[0046] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 And attached Figure 5 As shown, the second frame is a rectangular second frame 6 .

[0047] The above description is only a preferred embodiment of the present invention, and does not limit the patent protection scope of the present invention. Any equivalent transformations made using the contents of the present invention specification, directly or indirectly used in other related technical fields, are also included in the protection scope of the present invention.
