Description

Technical Field

[0001] This invention relates to the field of barrier gate technology, specifically a type of barrier gate. Background Technology

[0002] Existing barrier gates are generally divided into two types. One type is a channel access management device specifically used to restrict the passage of motor vehicles. This type is now widely used in highway toll stations and parking lot systems to manage vehicle access. The other type is a management device used to verify identity and prevent outsiders from entering certain facilities to isolate personnel. This type of barrier gate is now widely used in company entrances, residential community access points, and ticket gates at high-speed rail entrances.

[0003] Existing pedestrian gates have a problem: since they are mainly installed in areas with high pedestrian traffic, when people open the gate with their ID cards, if a child is standing in the direction the gate is opening, the gate may knock the child down, causing injury. Patent number CN219342949u, entitled "A Pedestrian Access Gate," employs a protective mechanism. When a child is standing in the direction the gate is opening, an electrical signal is activated, and under the control of the controller, the drive motor stops rotating, thus stopping the gate from opening. This effectively prevents children from being injured by the gate, improving the safety of pedestrian access gates during use and solving the aforementioned problem.

[0004] However, when using this type of barrier valve, there are sometimes dangerous individuals who directly force open the barrier valve and trespass into the facility. The barrier strength of the equipment is low, and each existing barrier gate requires a separate power source to open and close, which is costly in the production process. Therefore, it does not meet the current needs. In response, we have proposed a barrier valve. Summary of the Invention

[0005] The purpose of this invention is to provide a barrier gate to solve the problems mentioned in the background art, such as the occasional dangerous personnel who directly break open the barrier gate and enter the facility, the low barrier strength of the equipment, and the high cost of each existing barrier gate requiring a separate power source for opening and closing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a barrier gate, comprising a barrier gate body, a gate shaft movably mounted on one side inside the barrier gate body, a bevel gear A fixedly sleeved on the lower side of the outer surface of the gate shaft, the bevel gear A meshing with a bevel gear B, a gear shaft connected to the axis of the bevel gear B, a spur gear fixedly sleeved on one side of the outer surface of the gear shaft, the spur gear meshing with a gear rack, a connecting rod fixedly mounted on one side of the outer surface of the gear rack, and a lower pressure plate located on the outer surface of the barrier gate body at the other end of the connecting rod;

[0013] Preferably, an inclined push plate is provided above the two push blocks, and the surface of the inclined push plate facing the push blocks and the surface of the push blocks facing the strip fixing block are both inclined surfaces. A hydraulic cylinder installed inside the barrier gate body is connected to the middle position of the upper surface of the inclined push plate.

[0014] Preferably, a circular cover plate is provided above the hydraulic cylinder on the upper end face of the barrier gate body, and the barrier gate body and the circular cover plate are fixed together by screws.

[0015] Preferably, the locking anti-collision mechanism further includes two rectangular push blocks, which are located in front of the two rectangular fixed blocks respectively.

Detailed Implementation

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Please see Figures 1 to 6 An embodiment of the present invention provides: a barrier gate, including a barrier gate body 1, a gate shaft 2 movably installed on one side inside the barrier gate body 1, a bevel gear A5 fixedly sleeved on the lower side of the outer surface of the gate shaft 2, the bevel gear A5 meshing with a bevel gear B6, a gear shaft 7 connected to the axis of the bevel gear B6, a spur gear 8 fixedly sleeved on one side of the outer surface of the gear shaft 7, the spur gear 8 meshing with a toothed rack 9, a connecting rod 10 fixedly installed on one side of the outer surface of the toothed rack 9, and a lower pressure plate 11 located on the outer surface of the barrier gate body 1 at the other end of the connecting rod 10.

[0031] During use, check the operation of each mechanism and fix the device in the work area. When a person's face is recognized by the intelligent recognition device 23, the locking structure of the gate shaft 2 will be released. At this time, when a person steps on the upper and lower pressure plates 11 and pushes the lower pressure plate 11 downward, the gear rack 9 connected to it via the connecting rod 10 will also descend. As the gear rack 9 descends, the spur gear 8 meshing with it will also rotate. When the spur gear 8 rotates, the gear shaft 7 connected to the shaft of the spur gear 8 and the bevel gear B6 fixedly sleeved on the outer surface of the gear shaft 7 will also rotate. When the bevel gear B6 rotates, the bevel gear A5 meshing with it and the gate shaft 2 connected to the axis of the bevel gear A5 will also rotate. When the gate shaft 2 rotates, the gate 21 fixed to the outer surface of the gate shaft 2 and the protective plate 3 connected to the gate 21 by the elastic connecting rod 22 will also rotate. Through the rotation of the gate 21 and the protective plate 3, the passage of the barrier gate body 1 can be opened automatically. The above technical solution eliminates the need to install a power source inside the equipment to drive the gate 21 to rotate, thereby reducing the production cost of the equipment.

[0032] A gate 21 is fixedly installed on one side of the outer surface of the gate shaft 2, located outside the gate body 1. A locking anti-collision mechanism 4 is connected to the middle of the rear end face of the gate 21 and installed on the outer surface of the gate body 1. The locking anti-collision mechanism 4 includes a strip groove 401. A metal rod 402 is fixedly installed inside the strip groove 401. A metal sleeve 403 is movably sleeved on one side of the outer surface of the metal rod 402. A supporting metal rod 404 is provided between the metal sleeve 403 and the gate 21. The two ends of the supporting metal rod 404 are respectively connected to the metal sleeve 403 and the gate 21 through the shaft. By being locked by the metal sleeve 403, which cannot move backward, the supporting metal rod 404, which prevents the gate 21 from rotating, can improve the impact resistance of the gate 21. Through the above technical solution, the gate 21 can be prevented from being knocked open, thereby increasing the safety of the equipment.

[0033] Each of the four corners of the front end face of the gate 21 is fixed with an elastic connecting rod 22, and a protective plate 3 is fixed at the front end of the four elastic connecting rods 22.

[0034] The elastic connecting rod 22 includes a thin rod, a thick rod, and a shock-absorbing spring. The bottom end of the thin rod is inserted into the interior of the thick rod. The end face of the thin rod located inside the thick rod is connected to the shock-absorbing spring. When the gate 21 located in front of the protective plate 3 is impacted, it will squeeze the elastic connecting rod 22. Through the shock-absorbing spring located inside the elastic connecting rod 22, the impact force received by the gate 21 can be reduced.

[0035] Each of the four corners of the lower end face of the lower pressure plate 11 is fixed with a guide rod 13. The outer side of the bottom end of the guide rod 13 is provided with a guide groove 12 located inside the barrier gate body 1. The lower end face of the guide rod 13 is connected to a return spring 14 located inside the guide groove 12. When the lower pressure plate 11 is pushed down, the guide rod 13 will also penetrate into the return spring 14. Through the guidance of the four guide rods 13 and the four guide grooves 12, the lower pressure plate 11 can be kept in a parallel state when it descends, preventing it from tilting. During the descent, the guide rod 13 will also squeeze the return spring 14 connected to it. Through the reaction force of the squeezed return spring 14, after the personnel pass through the lower pressure plate 11, the lower pressure plate 11 will be pushed up to return to its original position. During the ascent of the lower pressure plate 11, through the transmission structure, the gate 21 will rotate back to its original position, thus isolating the passage inside the barrier gate body 1.

[0036] Two strip-shaped fixing grooves 15 are symmetrically arranged on both sides of the top end of the gate shaft 2. A push block 16 is provided on one side of each strip-shaped fixing groove 15, and a strip-shaped fixing block 17 that is inserted into the strip-shaped fixing groove 15 is fixed on one side of the outer surface of the push block 16. A spring 18 is connected to the other side of the outer surface of the push block 16. An inclined push plate 19 is provided above the two push blocks 16, and the surface of the inclined push plate 19 facing the push block 16 and the surface of the push block 16 facing the strip-shaped fixing block 17 are both inclined. On the upper surface of the inclined push plate 19, a hydraulic cylinder 20 installed inside the barrier gate body 1 is connected to the middle position. When the gate 21 is closed, the strip-shaped fixing block 17 located on the outer surface of the push block 16 is engaged with the strip-shaped fixing groove 15 located on the outer surface of the gate shaft 2. By engaging the strip-shaped fixing block 17 in the strip-shaped fixing groove 15, the gate shaft 2 can be fixed, thereby preventing the gate shaft 2 from rotating. Only when the face of the person passing through is recognized by the intelligent recognition device 23 can the gate shaft 2 be fixed. Only when the hydraulic cylinder 20, which is electrically connected to the intelligent identifier 23, is activated will it push the inclined push plate 19 connected to it downwards. As the inclined push plate 19 descends, the two push blocks 16 located below it will be pushed outwards. With the movement of the push blocks 16, the strip fixing block 17 will gradually leave the interior of the strip fixing groove 15. When the strip fixing block 17 has completely left the interior of the strip fixing groove 15, the gate will turn. The fixing of shaft 2 is released. Only when the fixing of gate shaft 2 is released will the lower pressure plate 11 be lowered when a person steps on the upper and lower pressure plates 11, and the gate 21 will be opened. As the lower pressure plate 11 rises, the gate shaft 2 will rotate back to its original angle. The reaction force of the spring 18 squeezed by the push block 16 when it moves outward will push the strip fixing block 17 inward again, so that it can be inserted into the strip fixing groove 15 to fix the gate shaft 2.

[0037] A circular cover plate is provided above the hydraulic cylinder 20 on the upper end face of the barrier gate body 1. The barrier gate body 1 and the circular cover plate are fixed together by screws. The circular cover plate can protect the hydraulic cylinder 20.

[0038] The locking anti-collision mechanism 4 also includes two rectangular push blocks 410. The two rectangular push blocks 410 are located in front of the two rectangular fixed blocks 405 respectively. The faces of the rectangular push blocks 410 facing the rectangular fixed blocks 405 and the faces of the rectangular fixed blocks 405 facing the rectangular push blocks 410 are both inclined. A single-bar cylinder 411 installed inside the barrier gate body 1 is connected to the middle position of the front face of each of the two rectangular push blocks 410. When the face of the person passing through is recognized by the intelligent recognition device 23, the single-bar cylinder 411, which is also electrically connected to it, will also move. The single-bar cylinder 411 can push the rectangular push blocks 410 backward. As the rectangular push blocks 410 move, the rectangular fixed blocks 405 behind them will be pushed outward. When the rectangular fixed blocks 405 completely leave the outer surface of the metal rod 402, the limit on the metal sleeve 403 will also be released.

[0039] A cylindrical groove 406 is provided on one side of the rectangular fixing block 405. A circular plate 407 is provided inside the cylindrical groove 406. A short rod 409 is connected to the axis of the circular plate 407. One end of the short rod 409 passes through the rectangular fixing block 405 and is fixed to the inner wall of the strip groove 401. A push spring 408 is connected between the circular plate 407 and the inner wall of the cylindrical groove 406. When the rectangular fixing block 405 moves outward, it will squeeze the push spring 408. Due to the reverse force of the squeezed push spring 408, when the gate 21 is closed again, the rectangular fixing block 405 will be pushed back towards the metal rod 402, returning it to its original position and restricting the movement of the metal sleeve 403 again.

[0040] The rectangular fixing block 405 has an arc-shaped surface 412 on the side facing the metal rod 402, and the rectangular fixing block 405 has a flat surface on the side facing the metal sleeve 403. The arc-shaped surface 412 allows the rectangular fixing block 405 to fit more closely to the metal rod 402, and the flat surface facing the metal sleeve 403 can effectively prevent the backward-moving metal sleeve 403 from pushing the two rectangular fixing blocks 405 outward.

[0041] A smart identifier 23 is fixedly installed on one side of the upper end face of the barrier gate body 1. The smart identifier 23 is also electrically connected to the single-bar cylinder 411 and the hydraulic cylinder 20. The smart identifier 23 can identify the personnel passing through. Only when the identification is successful will the single-bar cylinder 411 and the hydraulic cylinder 20 be started and the fixing and support of the gate shaft 2 be released.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
