Description

Technical Field

[0001] The utility model relates to a door opening aisle assembly based on foot control. Background Art

[0002] In places with a large flow of people such as office buildings, there are gates at the entrances and exits. Generally, people in the same group do not carry large pieces of luggage and need to pass quickly to avoid crowding, especially during the peak commuting hours. How to achieve quick passage has become an urgent technical problem to be solved. Currently, there are many gates that use face recognition or card recognition on the market.

[0003] Therefore, for occasions where people entering or leaving do not carry large pieces of luggage dragged on the ground, such as suitcases, trolleys, etc. Currently, the unpowered automatic reset doors used in similar occasions generally need to be pushed open by hand, or the body needs to be pressed tightly against the door body, and at the same time, the body needs to move forward to push open the door body. There are mainly two problems with this kind of automatic reset door. One is that people pay more attention to public health and safety and try to avoid touching the surfaces of public facilities and other objects; the other is that as an entrance door, it is generally required to prohibit people from leaving through this door. However, due to the limitations of the function of this kind of door, people inside can pull the door in the opposite direction and come out through this passage.

[0004] Based on the above two problems, a door opening aisle assembly based on foot control is designed. By stepping on the marked door opening pedal on the ground, the door panel is driven to open, thus avoiding people's hands or bodies from touching the door body and reducing the infection risk of bacteria, viruses or related infectious diseases (especially in hospitals). And when people are in a state similar to normal walking, they can pass smoothly, and the experience is better; for the problem that people who have entered the designated area come out in the opposite direction, this device is designed with a locking mechanism, which can only trigger the switch to unlock by stepping on the door opening pedal, and can continue to drive the door body to open, while the door cannot be rotated open by hand.

[0051] In order to provide a door opening control method, a foot-operated door opening method is provided, which uses a door opening aisle component based on foot control; the door opening method includes the following steps; S1, when no one passes, the door panel is closed, and the door opening pedal at the bottom is in an inclined state, inclined 30 degrees to the ground.

[0052] As a further improvement of the above technical solution:

[0053] When someone passes by, step on the door opening pedal according to the instructions on the door panel or the door opening pedal. The door opening pedal drives the internal mechanism to move, the door opening pedal runs to a horizontal state, and the door panel opens clockwise.

[0054] After the door is opened, the passerby steps forward with his other foot, continues to move forward, lifts the foot on the door opening pedal, steps forward, and leaves the passage. The door panel rotates counterclockwise to the closed state and locks under the action of the spring, returning to the state of step S1.

[0055] In step S1 initial state;

[0056] First, under the action of the return compression spring, the rack and gear mesh, generating a counterclockwise rotation torque. The return compression spring presses against the rack connecting block, causing it to maintain a tendency to move to the right. The right inclined surface on the other side of the rack connecting block contacts the driving roller. Then, the driving roller is connected to the connecting rod slider A via the pin A. The connecting rod slider A is connected to the driving connecting rod, thereby applying a pushing force to the door opening pedal, keeping it in a tilted state.

[0057] In step S2, when the door panel is in the closed state, it cannot be opened by pushing or pulling the door panel manually. The only way to unlock the door panel is to step on the door pedal and drive the door panel to open.

[0058] When a passing person starts to step on the door-opening pedal, first, buffering is carried out through a buffer spring and a buffer guide rod; then, after stepping on the door-opening pedal for a set stroke, the door-opening pedal presses on the unlocking roller; secondly, the unlocking slider moves downward, causing the unlocking protrusion on the unlocking slider to move downward, thereby pushing the unlocking long rod to rotate clockwise by a set angle, enabling the door shaft locking rod to break free from the restriction of the unlocking long rod. At the same time, the buffer guide rod compresses the buffer spring; thirdly, after unlocking, the door-opening pedal continues to be stepped on, and the driving link continues to push and act, transmitting power to the rack and gear, thereby opening the door panel;

[0059] When the door panel is fully opened, the door-opening pedal is limited by the support block A and the long support block B, providing support for the door-opening pedal to ensure the structural stability and the safety experience of passing persons.

[0060] Return to the initial state; first, a passing person steps on the door-opening pedal with one foot. When the door panel is opened, the passing person continues to move forward and steps out with the other foot; then, lift the foot stepping on the door-opening pedal and step forward to leave the passage. Under the elastic action of the reset compression spring, the buffer spring, the torsion spring member, and the unlocking compression spring, the door-opening pedal returns to the initial state.

[0061] The utility model is reasonable in design, low in cost, strong and durable, safe and reliable, simple to operate, time-saving and labor-saving, cost-saving, compact in structure and convenient to use. Description of the Drawings

[0073] As Figures 1-10 , taking the embodiment of the present utility model as an example of opening and closing a door, the closed state and the opened state of the door panel 42 are described as follows:

[0074] 1. When there is no one passing through, the door panel 42 is closed, and the door opening pedal 39 at the bottom is in an inclined state, inclined at 30 degrees to the ground. As Figure 1 . Figure 2 .

[0075] 2. When someone is passing through, according to the indication on the door panel 42 or the indication on the door opening pedal 39, step on the door opening pedal 39. The door opening pedal 39 drives the internal mechanism to act, and the door opening pedal 39 rotates to the horizontal state, and the door panel 42 rotates clockwise to open. As Figure 3 .

[0076] 3. After the door is opened, the passing person steps forward with the other foot, continues to move forward, lifts the foot stepping on the door opening pedal 39, steps forward, leaves the passage, and the door panel 42 rotates counterclockwise to the closed state and locks under the action of the return spring, returning to the state of step 1 above.

[0077] As Figures 1-10 , a detailed description of the overall mechanism of the present utility model;

[0078] 1. Schematic diagram of main components, which includes a bottom drive assembly arranged on the bottom, a door shaft 1 arranged on the bottom drive assembly, a door panel 42 arranged on the side of the door shaft 1, and a top support assembly arranged on the door shaft 1; when the door panel 42 is closed, the door opening pedal is tilted upwards by 30°.

[0079] 2. Description of the connection of the main structure

[0080] The bearing fixing seat 3 is fixed on the equipment housing, the rotating support 2 is installed on the bearing fixing seat 3, and the door shaft 1 is installed on the rotating support 2 to form a rotating connection.

[0081] The reset compression spring guide sleeve 6 is fixed on the equipment housing to limit the displacement of the reset compression spring 7 on the Figure 1 left side. The reset compression spring guide rod 8 and the reset compression spring guide sleeve 6 form a sliding connection.

[0082] The rack connection block 9 is fixed on the rack 5 at the left side position, the middle part is connected to the slider of the linear guide 10 by screws, and the right inclined surface forms a rolling connection with the driving roller 11.

[0083] The driving roller 11 forms a rolling connection with the connecting rod slider A13 through the pin shaft A12.

[0084] The connecting rod slider A13 forms a sliding connection through the buffer spring 14 and the buffer guide rod 15.

[0085] The driving connecting rod 20 forms a rotating connection with the connecting rod slider A13 through the pin shaft B16.

[0086] The driving connecting rod 20 forms a rotating connection with the connecting rod seat 21 through the pin shaft C22.

[0087] Both sides of the hinge member 26 are respectively connected to the torsion spring support 25 and the door opening pedal 39.

[0088] The unlocking roller 28 forms a rotating connection with the unlocking slider 27 through the pin shaft D46.

[0089] The unlocking slider 27 forms a sliding connection with the two guide rods on the unlocking guide post 30.

[0090] The unlocking long rod 33 forms a rotating connection with the guide rod on the tension spring base 32.

[0091] The unlocking tension spring 31 pulls one end of the unlocking long rod 33, making it have a tendency to rotate counterclockwise, and the other end presses on the unlocking slider 27 to limit its rotation position.

[0092] When the unlocking slider 27 is pressed down, the unlocking protrusion 47 moves downward, pushing open the unlocking long rod 33 and causing it to rotate clockwise by a certain angle, and the door hinge locking rod 34 is disengaged from the clockwise rotation restriction of the unlocking long rod 33.

[0093] 3. Main movement analysis

[0094] 1 Initial state

[0095] Under the action of the reset compression spring 7, the rack 5 meshes with the gear 4, generating a counterclockwise torque. The reset compression spring 7 presses against the rack connecting block 9 to keep it moving to the right. The other side of the rack connecting block 9 contacts the driving roller 11. The driving roller 11 is connected to the connecting rod slider A13 through the pin shaft A12, and the connecting rod slider A13 is connected to the driving connecting rod 20, thereby applying the previous pushing force to the door opening pedal 39, keeping the door opening pedal 39 in a state of tilting up by 30 degrees. The two torsion spring parts 24 have the function of overcoming the gravity of the door opening pedal and assisting the door opening pedal to reset, preventing the insufficient elastic force of the reset compression spring 7 to ensure the smooth operation of the mechanism.

[0096] 2 Door opening state

[0097] When the door device is in the closed state, it is impossible to open the door by pushing or pulling the door panel 42 by hand. Therefore, a in-place locking mechanism is designed in this device, and it can only be unlocked by stepping on the door opening pedal and driving the door panel 42 to open. When the passing person starts to step on the door opening pedal 39, in order to solve the problem of interference between the unlocking mechanism and the connecting rod driving mechanism during simultaneous driving, a spring buffer mechanism is designed at the connection position between the driving connecting rod 20 and the connecting rod slider A13, that is, the buffer spring 14 and the buffer guide rod 15 are added. In this way, when the door opening pedal is just stepped down by a certain stroke, the door opening pedal 39 presses on the unlocking roller 28, and the unlocking slider 27 moves downward, causing the unlocking protrusion 47 on the unlocking slider to move downward, thereby pushing the unlocking long rod 33 to rotate clockwise by a certain angle, and the door hinge locking rod 34 is disengaged from the restriction of the unlocking long rod 33. At this time, the buffer guide rod 15 compresses the buffer spring 14 to a certain extent, so that the entire driving mechanism will not finally hard-press the rack on the gear through transmission. After unlocking, when the door opening pedal is continuously stepped down, the driving connecting rod 20 can continue to push the mechanism to move, and the end of the mechanism transmits the power to the rack and gear mechanism, thereby opening the door panel 42.

[0098] After the door panel 42 is completely opened, the state of the bottom driving mechanism is as shown in the following figure. The two support blocks A35 and the long support block B36 are provided to support the door opening pedal 39 when the passing person steps on the door opening pedal, ensuring the stability of the structure and the safety experience of the passing person.

[0099] 3 Return to the initial state

[0100] A person passing through steps on the door-opening pedal 39 with one foot. After the door panel 42 opens, the person continues to move forward, steps out the other foot, then lifts the foot on the door-opening pedal and steps forward to leave the passage. At this time, under the elastic action of the reset compression spring 7, the buffer spring 14, the torsion spring member 24, and the unlocking compression spring 29, the entire mechanism operates, and the door-opening pedal 39 returns to its initial state.

[0101] The buffer stroke of the buffer spring 14 is compared with the action when the door-opening pedal is depressed. During this process, since there is no large resistance, the buffer spring 14 can be considered to have a very small virtual stroke, so that the unlocking protrusion 47 can first pass through one end of the unlocking long rod 33. Then, when the door shaft locking rod 34 is about to return to its initial state, it presses on the other end of the unlocking long rod 33, overcomes the pulling force of the unlocking tension spring 31, rotates to the locking angle, and is locked by the unlocking long rod 33.

[0102] 4 Other Structural Descriptions

[0103] In addition to the above main structure, in order to ensure the normal passage of people passing through, a sheet metal cover A50, a sheet metal cover B51, and a sheet metal cover C52 need to be installed. In this way, when a person passing through steps on the upper surface of this passage, the bottom of their foot can pass smoothly. When the door-opening pedal 39 is in the popped-up state, the highest point from the ground is 75 mm, and when the door-opening pedal is fully lowered, the height from the ground is 44 mm. The lower stepping height is convenient for personnel to operate.

[0104] An anti-slip rubber pad 53 is installed on the surface of the door-opening pedal 39, which can play an anti-slip role and has a more prominent reminder effect compared with the surrounding sheet metal materials. The text label "Step on to Open the Door" can be pasted.

[0105] In order to meet the requirements of preventing relatively large dust and sundries from entering the opening of the door-opening pedal, spandex high-elastic cloth 54 or other elastic materials are used. One end of it is respectively connected to the door-opening pedal 39 around its perimeter, and the other end is connected to the sheet metal cover B51 around its perimeter. When the door-opening pedal is lifted to the maximum height, the maximum linear distance of the gap at the opening is 36 mm. Using a high-elastic material about 1 mm thick can meet the stretching rate requirements. When the door-opening pedal is depressed, it can be retracted into the gap (controlled within 5 to 8 mm) around the door-opening pedal without affecting the operation of the mechanism.
