Description

Technical Field

[0001] The utility model relates to the field of supporting equipment for garbage rooms, in particular to a foot-operated door-opening mechanism. Background Art

[0002] At present, the door of the garbage room basically adopts a foot-operated door opening mechanism to control the opening and closing of the door. The foot-operated door opening and closing mechanism currently used is shown in the patent announcement document CN203005443U. There is a problem in the use of the door opening and closing mechanism of this structure, that is, there is no damping device set for the connecting rod (the figure mark number 10 in the document) in the door opening and closing mechanism of this structure, so the door opening and closing mechanism of this structure is very easy to cause the door panel to be damaged due to the door panel closing speed too fast during the closing process. Utility Model Content

[0003] In view of the above problems, the utility model provides a foot-operated door opening mechanism.

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

[0005] A foot-operated door opening mechanism comprises a bracket, a door frame, a door panel, a door opening connecting rod, a first mounting shaft, a second mounting shaft, a connecting plate and a foot-operated assembly, wherein the door frame is arranged on the bracket, the door panel is rotatably arranged on the bracket via the first mounting shaft, the second mounting shaft is rotatably arranged on the bracket, the first mounting shaft is fixedly matched with the door opening connecting rod, the door opening connecting rod is rotatably matched with one end of the connecting plate, the other end of the connecting plate is matched with the second mounting shaft (relative rotation cannot occur between the second mounting shaft and the connecting plate), the foot-operated assembly is matched with the second mounting shaft, and also comprises a one-way damper, a connecting frame is arranged on the door panel, the connecting frame is fixedly matched with the first mounting shaft, the one-way damper is arranged on the bracket, and the rotating shaft of the one-way damper is fixedly matched with the connecting frame.

[0006] When the user steps on the pedal assembly, the pedal assembly drives the second mounting shaft to rotate, and the rotation of the second mounting shaft drives the door opening link to move up and down. The up and down movement of the door opening link drives the first mounting shaft to rotate, and the rotation of the first mounting shaft drives the door panel to rotate. The door panel rotates, thereby opening the door. When the door is opened, the shaft of the one-way damper does not hinder the rotation of the connecting plate. When the door needs to be closed, the user's foot no longer applies force to the pedal assembly, and the pedal assembly no longer has the tendency to drive the second mounting shaft to rotate. At this time, the door panel has a tendency to slide down and rotate to close under the action of its own gravity. At this time, the shaft on the one-way damper starts to work, and the shaft on the one-way damper starts to cause resistance to the rotation of the connecting frame, so that the door panel closes slowly, reducing the probability of damage to the door panel during the closing process.

[0007] To summarize, the above-mentioned mechanism is provided with a one-way damper, which does not cause resistance to the rotation of the connecting frame when the door is opened by foot, and hinders the rotation of the connecting frame when the door is closed naturally, thereby reducing the probability of the door panel being damaged due to closing the door too quickly.

[0008] Optionally, it also includes an anti-collision baffle, which is arranged on the bracket and is an L-shaped anti-collision baffle.

[0009] The function of the anti-collision baffle is to contact with the door opening link. When the door is opened, when the door opening link moves to contact with the anti-collision baffle, the door opening link will not be able to move further, thereby limiting the rotation range of the connecting frame (i.e., the door panel).

[0010] Optionally, the foot pedal assembly includes a foot pedal, a foot pedal seat and a pulling connecting rod, the foot pedal seat is located on one side of the bracket and is in a fixed state, the foot pedal is rotatably mounted on the foot pedal seat through a foot pedal pin, one end of the pulling connecting rod is engaged with the foot pedal, and the other end of the pulling connecting rod is engaged with the second mounting shaft.

[0011] In the pedal assembly, the user can drive the pull connecting rod to move by stepping on the pedal, and the movement of the pull connecting rod drives the second installation shaft to rotate.

[0012] Optionally, it also includes a return torsion spring, which is sleeved on the pedal pin, one end of the return torsion spring abuts against the foot pedal, and the other end of the return torsion spring abuts against the pedal seat.

[0013] The function of the return torsion spring is to drive the pedal to return to its original position before being stepped on after the user finishes stepping on the pedal.

[0014] Optionally, a connecting cover is also included, wherein the connecting cover is fixed together with the footrest seat and the bracket, and the connecting cover is located between the footrest seat and the bracket.

[0015] The connecting cover has the functions of covering the pulling connecting rod and connecting the bracket and the footrest.

[0016] Optionally, there are two door opening connecting rods, and the two door opening connecting rods are in parallel, and the door panel is located between the two parallel door opening connecting rods.

[0017] Optionally, the first installation shaft and the second installation shaft are in parallel.

[0018] Optionally, the first mounting shaft and the second mounting shaft are both in a perpendicular position to the door opening connecting rod.

[0019] The beneficial effect of the utility model is that by arranging a one-way damper, the one-way damper does not cause resistance to the rotation of the connecting frame when the door is opened by foot, and the one-way damper hinders the rotation of the connecting frame when the door is closed naturally, thereby reducing the probability of the door panel being damaged due to closing the door too quickly.

DETAILED DESCRIPTION

[0027] The utility model is described in detail below in conjunction with the accompanying drawings.

[0028] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 As shown, a foot-operated door opening mechanism includes a bracket 1, a door frame 401, a door panel 3, a door opening link 6, a first mounting shaft 12, a second mounting shaft 13, a connecting plate 7 and a foot pedal assembly, wherein the door frame 401 is arranged on the bracket 1, the door panel 3 is rotatably arranged on the bracket 1 through the first mounting shaft 12, the second mounting shaft 13 is rotatably arranged on the bracket 1, the first mounting shaft is fixedly matched with the door opening link 6, the door opening link 6 is rotatably matched with one end of the connecting plate 7, the other end of the connecting plate 7 is matched with the second mounting shaft 13 (relative rotation cannot occur between the second mounting shaft 13 and the connecting plate 7), the foot pedal assembly is matched with the second mounting shaft 13, and also includes a one-way damper 14, a connecting frame 2 is arranged on the door panel 3, the connecting frame 2 is fixedly matched with the first mounting shaft 12, the one-way damper 14 is arranged on the bracket 1, and the shaft of the one-way damper 14 is fixedly matched with the connecting frame 2.

[0029] In the foot-operated door opening mechanism, in the natural state, the door panel 3 covers the door frame 401, and the entire mechanism is in a closed state. When opening the door, the user steps on the foot pedal assembly, and the foot pedal assembly is used to drive the second mounting shaft 13 to rotate. When the second mounting shaft 13 rotates, it drives the door opening connecting rod 6 to move up and down. The up and down movement of the door opening connecting rod 6 will drive the first mounting shaft 12 to rotate. The rotation of the first mounting shaft 12 will drive the door panel 3 to rotate. The door panel 3 rotates, thereby realizing the door opening. When opening the door, the rotating shaft of the one-way damper 14 does not rotate. The rotation of the connecting plate 7 is hindered. When the door needs to be closed, the user's foot no longer applies force to the foot pedal assembly, and the foot pedal assembly no longer has the tendency to drive the second mounting shaft 13 to rotate. At this time, the door panel 3 has a tendency to slide down and rotate to close under the action of its own gravity. At this time, the shaft on the one-way damper 14 begins to work, and the shaft on the one-way damper 14 begins to create resistance to the rotation of the connecting frame 2, so that the door panel 3 closes slowly, reducing the probability of damage to the door panel 3 during the closing process.

[0030] In summary, the above-mentioned mechanism is provided with a one-way damper 14. The one-way damper 14 does not cause resistance to the rotation of the connecting frame 2 when the door is opened by foot, and hinders the rotation of the connecting frame 2 when the door is closed naturally, thereby reducing the probability of the door panel 3 being damaged due to closing the door too quickly.

[0031] Specifically in this mechanism, a panel 4 is provided on the bracket 1 , and the door frame 401 is the opening on the panel 4 .

[0032] In the present mechanism, a locking rod 15 is inserted and fixed at one end of the second installation shaft 13 , and the locking rod 15 is used to prevent the connecting plate 7 from being separated from the second installation shaft 13 .

[0033] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 As shown, it also includes an anti-collision baffle 5, which is arranged on the bracket 1 and is an L-shaped anti-collision baffle 5.

[0034] The function of the anti-collision baffle 5 is to contact with the door opening link 6. When the door is opened, when the door opening link 6 moves to contact with the anti-collision baffle 5, the door opening link 6 will not be able to move further, thereby limiting the rotation range of the connecting frame 2 (i.e., the door panel 3).

[0035] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 As shown, the foot pedal assembly includes a foot pedal 10, a foot pedal seat 11 and a pulling connecting rod. The foot pedal seat 11 is located on one side of the bracket 1, and the foot pedal seat 11 is in a fixed state. The foot pedal 10 is rotatably mounted on the foot pedal seat 11 through a foot pedal pin 16. One end of the pulling connecting rod is matched with the foot pedal 10, and the other end of the pulling connecting rod is matched with the second mounting shaft 13.

[0036] In the pedal assembly, the user can drive the pull rod to move by stepping on the pedal 10, and the movement of the pull rod drives the second mounting shaft 13 to rotate.

[0037] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 As shown, the reset torsion spring 17 is also included. The reset torsion spring 17 is sleeved on the pedal pin 16 . One end of the reset torsion spring 17 abuts against the pedal 10 , and the other end of the reset torsion spring 17 abuts against the pedal seat 11 .

[0038] The function of the return torsion spring 17 is to drive the pedal 10 to return to the original position before being stepped on after the user finishes stepping on the pedal 10 .

[0039] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6As shown, a connecting cover is also included, which is fixed together with the footrest seat 11 and the bracket 1, and the connecting cover is located between the footrest seat 11 and the bracket 1.

[0040] The connecting cover has the functions of covering the pulling connecting rod and connecting the bracket 1 and the pedal seat 11 .

[0041] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 As shown, there are two door opening connecting rods 6 , and the two door opening connecting rods 6 are in a parallel state, and the door panel 3 is located between the two parallel door opening connecting rods 6 .

[0042] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 As shown, the first installation shaft 12 and the second installation shaft 13 are in parallel.

[0043] As attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 , Attachment Figure 4 , Attachment Figure 5 And attached Figure 6 As shown, the first installation shaft 12 and the second installation shaft 13 are both in a vertical position with respect to the door opening connecting rod 6 .

[0044] Similarly, in order to improve the stability of the bracket 1, a stabilizing rod 8 is provided at one end of the bracket 1, and the stabilizing rod 8 is a square tube-shaped stabilizing rod 8.

[0045] Similarly, in the present mechanism, a two-section second mounting shaft (ie, composed of two rods) is adopted. In other equivalent embodiments, a one-section second mounting shaft (ie, composed of only one rod) may also be adopted.
