DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 The utility model provides a technical solution: an automatic door which is convenient for limiting an external signal rod, comprising: a door frame 1, a pulley 7 and an operating machine 8. A driving motor 2 is installed on the top of the door frame 1. The output end of the driving motor 2 is connected to a bevel gear set 3 through an output shaft. A screw rod 4 is connected through the middle of the bevel gear set 3. A screw sleeve 5 is sleeved on the outer side of the screw rod 4. The bottom of the screw sleeve 5 is connected to a door body 6. The pulley 7 is installed at the bottom of the door body 6. The operating machine 8 is installed on one side of the door frame 1.

[0022] A fixed block 9 is installed on one side of the operating machine 8, and push rods 10 are connected through both sides of the fixed block 9. A connecting block 11 is installed on one side of the push rod 10. A movable spring 12 is connected between the push rod 10 and the groove of the fixed block 9. Slide blocks 13 are connected through sliding grooves on both sides of the connecting block 11. A connecting rod 14 is connected to one side of the slider 13. A protrusion 15 that penetrates the fixed block 9 is connected between the two groups of connecting rods 14. A clamping block 16 is installed at one end of the protrusion 15. A positioning block 17 is sleeved on the outer side of the protrusion 15. A signal rod body 18 is installed between the two groups of positioning blocks 17. The push rod 10 forms a telescopic structure with the fixed block 9 through the movable spring 12.

[0023] In specific implementation, the automatic door that is convenient for limiting the external signal rod, when it is necessary to install the signal rod body 18 to one side of the operating machine 8, the push rods 10 on both sides of the fixed block 9 can be squeezed toward the inside of the fixed block 9. When the push rods 10 are squeezed, the connecting block 11 is squeezed, so that the two groups of connecting blocks 11 move closer to each other. At the same time, the push rods 10 will cause the movable spring 12 to be in a stretched state when moving. An inclined slide groove is provided on both sides of the connecting block 11, and a slider 13 is connected through the slide groove. When the connecting block 11 moves, the slider 13 slides along the inclined groove, and the other side of the slider 13 is connected to the connecting rod 14. When the slider 13 moves, it pushes the connecting rod 14 to move to one side. The movement of the connecting rod 14 drives the protrusion 15 and the block 16 to move. When the protrusion 15 moves to the concave groove of the positioning block 17 After the grooves are aligned, the signal rod body 18 can be inserted into the interface on one side of the operating machine 8 through the hole in the middle of the fixing block 9, and then the push rod 10 is released. The push rod 10 will be reset by the movable spring 12 and drive the slider 13 to slide in the opposite direction through the connecting block 11. The reverse sliding of the slider 13 will pull the connecting rod 14 to move in the opposite direction, so that the protrusion 15 drives the card block 16 to move in the opposite direction. At this time, the card block 16 can be connected to the groove of the positioning block 17 and fix the positioning block 17. The positioning block 17 is installed at both ends of the signal rod body 18. At this time, the signal rod body 18 will be fixed on one side of the operating machine 8, which is convenient for quickly limiting and fixing the signal rod body 18. At the same time, it can also prevent the signal rod body 18 from loosening and falling, which is convenient for receiving signals, thereby realizing remote control of the door body 6.

[0024] See also Figure 1 , Figure 2 and Figure 3 It can be seen that when in use, the signal rod body 18 can be quickly connected to one side of the operating machine 8 through the interface according to the use requirements, and the signal rod body 18 can be limited and fixed by the cooperation of the clamping block 16 and the positioning block 17.

[0025] A pressure rod 19 is installed at the bottom of the door frame 1 through a slide groove, and a telescopic rod 20 is connected to the bottom of the pressure rod 19 through a rotating shaft. A sleeve 21 is sleeved on the end of the telescopic rod 20 away from the pressure rod 19, and a telescopic spring 22 is installed inside the sleeve 21. A return spring 23 is installed between the two groups of pressure rods 19, and the end of the sleeve 21 away from the telescopic rod 20 is connected to the groove at the bottom of the door frame 1 through a rotating shaft.

[0026] In specific implementation, the automatic door with an external signal rod that is convenient for limiting the position will make the two sets of door bodies 6 move closer to each other when closing the automatic door, and drive the pulley 7 at the bottom to move closer to each other. When the pulley 7 moves, it will squeeze the pressure rod 19, so that the pressure rod 19 shrinks toward the inside of the door frame 1. The bottom of the pressure rod 19 is connected to the telescopic rod 20 through a rotating shaft, and the end of the telescopic rod 20 is sleeved with a sleeve 21, and the other side of the sleeve 21 is connected to the groove of the door frame 1 through a rotating shaft. When the pressure rod 19 is squeezed and moved, The telescopic rod 20 and the sleeve 21 are rotated by the rotating shaft, and the telescopic rod 20 is squeezed at the same time, so that the telescopic rod 20 is contracted into the sleeve 21, and the telescopic spring 22 inside the sleeve 21 is squeezed. When the two groups of pressure rods 19 move close to each other, the return spring 23 in the middle of the pressure rod 19 is squeezed, so that the return spring 23 is in a compressed state. Through the action of the telescopic spring 22 and the return spring 23, the door body 6 can be buffered, thereby preventing the two groups of door bodies 6 from colliding with each other;

[0027] When the automatic door is opened, the pulley 7 will also squeeze the pressure rod 19 on the other side of the slide groove of the door frame 1, so that the pressure rod 19 squeezes the telescopic rod 20, and the pressure rod 19 and the sleeve 21 rotate through the rotating shaft. The telescopic rod 20 will also squeeze the telescopic spring 22, and the pressure rod 19 will also squeeze the return spring 23 on one side, thereby avoiding the door body 6 and the door frame 1 from colliding.

[0028] See also Figure 1 and Figure 4 It can be seen that when in use, the telescopic rod 20 can be retracted into the interior of the sleeve 21 and squeeze the telescopic spring 22, while the pressure rod 19 squeezes the return spring 23, thereby buffering the door body 6 and avoiding severe impact when the door body 6 is opened and closed.

[0029] In summary: when the automatic door with an external signal rod that is convenient for limiting position is used, the drive motor 2 can be started, and the drive motor 2 will drive the bevel gear set 3 to rotate through the output shaft. The bevel gear set 3 is connected by two bevel gears that mesh with each other, one of which is connected to the output shaft of the drive motor 2, and the other is connected to the screw rod 4. At this time, the bevel gear set 3 will drive the screw rod 4 to rotate, and the outer side of the screw rod 4 is sleeved with a screw sleeve 5. When the screw rod 4 rotates, it will drive the door body 6 at the bottom to slide through the screw sleeve 5, and the door body 6 will slide through the bottom while sliding. The pulley 7 slides along the track at the bottom of the door frame 1, thereby ensuring the stability of the entire door body 6, allowing the door body 6 to be opened and closed freely, and the door body 6 can also be operated and controlled by an operating machine 8 on one side of the door frame 1. During operation, a specified password can be entered or a fingerprint can be recorded to control the door body 6, thereby facilitating operation.
