Description

Technical Field

[0001] This application relates to the field of safety barrier technology, and in particular to a safety barrier with a manual emergency structure. Background Technology

[0002] Security gates are widely used in residential areas, parking lots, and park entrances to control vehicle access. Conventional gates rely on a motor to drive the output shaft crank arm, connecting rod, and main shaft crank arm to raise and lower the gate arm, with a tension spring to counteract the gate arm's weight. In case of motor failure, current technology requires manual operation to raise the arm, necessitating continuous handwheel control by staff, increasing their workload and posing a risk of the gate arm falling.

[0003] The existing manual handwheel of the barrier gate lacks a self-locking structure. In case of power failure and emergency manual operation, the staff needs to hold the handwheel continuously. After releasing the handwheel, the gate arm will rebound and deviate due to its own weight and spring tension, which is inconvenient to operate and can easily cause safety accidents such as crushing vehicles or trapping people.

[0027] By adopting the above technical solution, the locking block inserted into the locking groove can be automatically reinforced and locked, thereby effectively ensuring the stability of the safety barrier after installation.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The safety barrier gate with a manual emergency structure described in this application, through the setting of a drive mechanism and a magnetic induction limit mechanism, enables the safety barrier gate to rotate clockwise or counterclockwise during actual use. This rotation of the motor sequentially drives the output shaft crank arm and connecting rod to rotate the main shaft crank arm, thereby realizing the raising and lowering of the barrier arm. Simultaneously, in the event of a power outage, the handwheel can be manually turned to directly drive the motor connecting shaft 206 to rotate, allowing manual raising and lowering of the barrier arm. Furthermore, this application uses a plug seat, a vertical limit plug, and a magnetic back plate to form a magnetic induction limit mechanism, which can accurately identify the vertically open and horizontally closed positions of the barrier arm, controlling the motor to stop and preventing over-rotation. Simultaneously, a spring hook is used to fine-tune the installation position of the tension spring, adjusting the spring tension to suit the needs of barrier arms of different lengths, optimizing the balance effect. Moreover, the tension spring is used to counteract the weight of the barrier arm, reducing motor power consumption, and ensuring smooth raising and lowering of the barrier arm, thus guaranteeing its safe use.

[0030] 2. The safety barrier gate with a manual emergency structure described in this application, through the setting of a fixing mechanism, allows the barrier gate box to be inserted into the insertion slot on the mounting base via a plug-in post during installation. Then, by rotating the rotating block with an external hexagonal wrench, the rotation of the rotating block drives the vertical shaft to rotate. The rotation of the vertical shaft, under the action of two bevel gears, drives the bidirectional threaded post to rotate. The rotation of the bidirectional threaded post drives two moving plates to move towards the center simultaneously, thereby causing the locking block to automatically insert into the locking slot on the plug-in post, achieving effective fixing of the plug-in post, and thus achieving effective fixing between the barrier gate box and the mounting base.

[0031] 3. The safety barrier with a manual emergency structure described in this application, by setting a sealing mechanism, can squeeze two rectangular telescopic inflatable airbags respectively during the process of the two moving plates moving towards the middle at the same time, so that the gas in the two rectangular telescopic inflatable airbags enters the annular inflatable sealing airbag through the connecting pipe, thereby achieving effective sealing of the gap between the insertion slot and the insertion post.

[0032] 4. The safety barrier with a manual emergency structure described in this application, through the setting of a reinforcement mechanism, can drive two straight racks to move simultaneously towards the center as the two moving plates move towards the center. When the locking block just enters the locking groove, the straight racks mesh with the gear plate and drive the gear plate to rotate. The rotation of the gear plate drives the vertical screw to rotate, and the rotation of the vertical screw drives the internal threaded top cylinder to move upward, so that the top of the annular reinforcement cylinder abuts against the lower surface of the locking block, and drives the vertical return spring to compress. When the locking block is fully inserted into the locking groove, the annular reinforcement cylinder corresponds to the reinforcement groove. Under the action of the vertical return spring, the annular reinforcement cylinder can automatically insert into the reinforcement groove, realizing automatic reinforcement and locking of the locking block inserted into the locking groove, thereby effectively ensuring the stability of the safety barrier after installation.

[0052] Please refer to this carefully. Figure 1 , Figure 2 The inner wall of the barrier gate box 101 is rotatably provided with a connecting shaft 205. The other end of the output shaft crank arm 202 is fixedly connected to the end surface of the connecting shaft 205. The motor 201 is fixedly installed on the inner wall of the barrier gate box 101, and the output end of the motor 201 is fixedly provided with a connecting shaft 206. The surfaces of the connecting shaft 206 and the connecting shaft 205 are both fixedly provided with meshing bevel gears.

[0053] Specifically, the rotation of the motor 201, under the action of the bevel gear, can drive the connecting shaft 205 to rotate, thereby driving the output shaft crank arm 202 to rotate.

[0054] Please refer to this carefully. Figure 1 , Figure 2 The bottom of the motor 201 is provided with, from top to bottom, a ratchet self-locking unit 207, an overrunning clutch 208 and a handwheel 209, which are integrated with the motor 201.

[0055] Specifically, a one-way overrunning clutch 208 and a ratchet self-locking unit 207 are installed on the handwheel 209, which can release the handwheel 209 after it is turned to a certain position, thus preventing the operator from continuously holding the handwheel 209 steady.

[0056] Please refer to this carefully. Figure 1 , Figure 2 The end of the main shaft crank arm 204 is provided with a spring hook 2010 which is an integral structure with the main shaft crank arm 204. A tension spring 2011 is fixedly provided on the surface of the spring hook 2010, and the bottom end of the tension spring 2011 is fixedly connected to the inner wall of the barrier box 101.

[0057] Specifically, the spring hook 2010 is used to fine-tune the installation position of the tension spring 2011 and adjust the spring tension to match the needs of different length gate arms 102, optimize the balance effect, and the tension spring 2011 is used to counteract the weight of the gate arm 102, reduce the power consumption of the motor 201, and at the same time make the gate arm 102 rise and fall smoothly to ensure the safety of the gate arm 102.

[0058] Please refer to this carefully. Figure 1 , Figure 2 The magnet back plate 303 is fixed to the inner wall of the barrier box 101 by screws. The plug seat 301 is rotatably set inside the barrier box 101 and corresponds to the magnet back plate 303. The vertical limiting plug 302 and the plug seat 301 are an integrated L-shaped structure.

[0060] In this embodiment, by setting up a drive mechanism 200 and a magnetic induction limit mechanism 300, the safety barrier can, during actual use, rotate clockwise or counterclockwise through the motor 201, which in turn drives the main shaft crank arm 204 to rotate via the output shaft crank arm 202 and connecting rod 203, thereby realizing the raising and lowering actions of the barrier arm 102. Simultaneously, in the event of a power outage, the handwheel 209 can be manually turned to directly drive the motor 201 connecting shaft 206 to rotate, allowing for manual raising and lowering of the barrier arm. Furthermore, this application utilizes the plug seat 301 and vertical... The limit plug 302 and the magnet back plate 303 constitute the magnetic induction limit mechanism 300, which can accurately identify the vertical opening and horizontal closing positions of the gate arm 102, control the motor 201 to stop, and prevent over-rotation. At the same time, the spring hook 2010 is used to fine-tune the installation position of the tension spring 2011 and adjust the spring tension to meet the needs of gate arms 102 of different lengths and optimize the balance effect. Moreover, the tension spring 2011 is used to counteract the weight of the gate arm 102, reduce the power consumption of the motor 201, and make the gate arm 102 rise and fall smoothly to ensure the safety of the gate arm 102.

[0061] Example 2

[0062] Based on Example 1, referring to Figures 3 to 7 And unlike Example 1, the following is true:

[0063] Please refer to this carefully. Figure 4 , Figure 5 The bottom of the barrier gate column 100 is provided with a fixing mechanism 400. The fixing mechanism 400 includes a mounting base 401 integrally cast with concrete and a plug-in column 402 fixed to the bottom of the barrier gate box 101. The upper surface of the mounting base 401 is provided with a plug-in groove 403 adapted to the plug-in column 402. The fixing mechanism 400 also includes a U-shaped cavity 404 opened inside the mounting base 401 and two symmetrical movable plates 405 slidably disposed on the inner wall of the U-shaped cavity 404. Locking blocks 406 are fixed on the opposite surfaces of the two movable plates 405. Rectangular holes adapted to the locking blocks 406 and extending into the plug-in groove 403 are opened on both sides of the inner wall of the U-shaped cavity 404. Locking grooves 407 adapted to the locking blocks 406 are opened on both sides of the plug-in column 402.

[0064] Specifically, the barrier gate box 101 can be inserted into the insertion slot 403 on the mounting base 401 via the insertion post 402, thereby achieving pre-positioning between the barrier gate box 101 and the mounting base 401.

[0065] Please refer to this carefully. Figure 4 , Figure 5 The inner wall of the U-shaped cavity 404 is rotatably provided with a bidirectional threaded post 408, and the surfaces of the two moving plates 405 are provided with threaded holes that are threadedly connected to the outer surface of the bidirectional threaded post 408. The interior and upper surface of the mounting base 401 are respectively provided with corresponding connecting cavities and rotating grooves. The inner bottom wall of the rotating groove is rotatably provided with a vertical shaft 409 extending into the interior of the connecting cavity. The top end of the vertical shaft 409 is fixed with a rotating block 4010, and the upper surface of the rotating block 4010 is provided with a hexagonal operating groove. One end of the bidirectional threaded post 408 extends into the interior of the connecting cavity, and the one end of the bidirectional threaded post 408 and the surface of the vertical shaft 409 are both fixed with mutually meshing bevel gears 4011.

[0066] Specifically, the rotation of the rotating block 4010 can drive the vertical shaft 409 to rotate, and under the action of the two bevel gears 4011, the bidirectional threaded column 408 can be driven to rotate automatically. The rotation of the bidirectional threaded column 408 drives the two moving plates 405 to move towards the middle at the same time, and drives the two locking blocks 406 to be inserted into the two locking grooves 407 respectively, so as to effectively fix and lock the plug-in column 402.

[0067] In this invention, by setting a fixing mechanism 400, the barrier gate box 101 can be inserted into the insertion slot 403 on the mounting base 401 via the insertion post 402 during installation.

The rotation of the vertical shaft 409 drives the bidirectional threaded post 408 to rotate under the action of two bevel gears 4011. The rotation of the bidirectional threaded post 408 drives the two moving plates 405 to move towards the center at the same time, thereby causing the locking block 406 to automatically insert into the locking slot 407 on the insertion post 402, realizing the effective fixing of the insertion post 402, and thus realizing the effective fixing between the barrier gate box 101 and the mounting base 401.

[0068] Please refer to this carefully. Figure 4 , Figure 6 The top inner wall of the insertion groove 403 is provided with a sealing mechanism 500. The sealing mechanism 500 includes an annular mounting groove opened on the top inner wall of the insertion groove 403, and an annular inflatable sealing airbag 501 fixed on the inner wall of the annular mounting groove. The sealing mechanism 500 also includes two symmetrical rectangular telescopic inflatable airbags 502 symmetrically fixed on the inner wall of the U-shaped cavity 404 and corresponding to the two moving plates 405 respectively. The inner wall of the rectangular telescopic inflatable airbags 502 is provided with a transverse return spring 503. The ends of the two rectangular telescopic inflatable airbags 502 are provided with a connecting pipe 504 that communicates with the annular inflatable sealing airbag 501.

[0069] Specifically, it can effectively seal the gap between the insertion slot 403 and the insertion post 402.

[0070] In this invention, by setting a sealing mechanism 500, the two rectangular telescopic inflatable airbags 502 can be squeezed respectively during the process of the two moving plates 405 moving towards the middle at the same time. This allows the gas in the two rectangular telescopic inflatable airbags 502 to enter the annular inflatable sealing airbag 501 through the connecting pipe 504, thereby achieving effective sealing of the gap between the insertion groove 403 and the insertion post 402.

[0071] Please refer to this carefully. Figure 4 , Figure 7The locking groove 407 is internally equipped with a reinforcing mechanism 600. The reinforcing mechanism 600 includes a rectangular cavity 601 formed inside the mounting base 401, and two symmetrical vertical lead screws 602 rotatably disposed on the bottom wall of the rectangular cavity 601.

The inner wall of the annular sliding groove is slidably provided with an annular reinforcing cylinder 605 adapted to the reinforcing groove 604. The bottom end of the annular reinforcing cylinder 605 is fixed with several vertical return springs 606 in a circumferential array. The bottom end of the vertical return springs 606 is fixedly connected to the inner bottom wall of the annular groove. The outer ring surface of the bottom end of the internal thread top cylinder 603 is fixed with a limiting ring 607. The inner top wall of the rectangular cavity 601 is fixed with a limiting rod 608 that is slidably connected to the inner wall of the limiting ring 607. The reinforcing mechanism 600 also includes two straight racks 609 fixed on the opposite sides of the two moving plates 405, and a gear plate 6010 fixed on the outer surface of the two vertical screws 602 and adapted to the two straight racks 609. The inner walls on both sides of the U-shaped cavity 404 are provided with transverse holes that extend into the rectangular cavity 601 and are slidably connected to the outer surface of the two straight racks 609.

[0072] Specifically, it enables automatic reinforcement and locking of the locking block 406 inserted into the locking groove 407, thereby effectively ensuring the stability of the safety barrier after installation.

[0073] The reinforcement mechanism 600, when the two moving plates 405 move towards the center simultaneously, drives the two racks 609 to move towards the center simultaneously as well. When the locking block 406 just enters the locking groove 407, the racks 609 mesh with the gear disc 6010, causing the gear disc 6010 to rotate. The rotation of the gear disc 6010 drives the vertical lead screw 602 to rotate, which in turn drives the internal threaded top cylinder 603 to move upwards, thus moving the annular reinforcement cylinder 60... The top of 5 abuts against the lower surface of the locking block 406, and drives the vertical return spring 606 to compress. When the locking block 406 is fully inserted into the locking groove 407, the annular reinforcing cylinder 605 corresponds to the reinforcing groove 604. The annular reinforcing cylinder 605 can automatically insert into the reinforcing groove 604 under the action of the vertical return spring 606, so as to automatically reinforce and lock the locking block 406 inserted in the locking groove 407, thereby effectively ensuring the stability of the safety barrier after installation.
