Description

Technical Field

[0001] This invention relates to the field of security inspection equipment technology, specifically to a turnstile with a gate sheath. Background Technology

[0002] Turnstiles are devices used to manage pedestrian flow and control pedestrian access. They are widely used in areas with high traffic such as subways, airports, and shopping malls. Most turnstiles are equipped with infrared sensors to detect whether pedestrians have passed through. Common turnstile types include wing gates, tripod turnstiles, and swing gates. Wing gates use a drive device to rotate and open the gate body. When the infrared sensor detects that a pedestrian has passed through the turnstile, the drive device will control the gate body to close.

[0003] When pedestrians are using a wing gate with children, if the adult passes through first and the infrared sensor on the wing gate detects someone passing through, the control system will close the wing gate, and the gate panel will pop out from inside the gate. This can easily trap and injure children behind, especially children aged 4 to 6 whose height is similar to that of the gate panel. They are also playful and energetic, and may delay their passage by playing around while passing through the gate. If the gate closes the gate panel, it can easily trap the child's head, causing serious injury. Summary of the Invention

[0004] The purpose of this invention is to provide a turnstile with a gate sheath to solve the problem mentioned in the background art that existing turnstiles are prone to injuring pedestrians when closing due to external interference.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention provides a turnstile with a gate sheath, comprising multiple turnstile bodies spaced apart to form a passage. Each turnstile body contains a gate body for controlling the opening and closing of the passage. An opening is provided on the side wall of the turnstile body to accommodate the opening and closing of the gate body. An anti-pinch mechanism is provided at one end of the gate body extending beyond the turnstile body. The anti-pinch mechanism includes an anti-pinch plate movably mounted on the gate body and capable of reciprocating motion. The anti-pinch plate deforms upon impact to increase the force-bearing area and reduce impact damage. A gate sheath body is located inside the turnstile body, and the gate sheath body moves vertically up and down with the opening of the gate body to open and close the opening.

[0007] Furthermore, the gate body extends out of the gate body and has an assembly groove at one end. The anti-pinch plate is movably assembled in the assembly groove. The anti-pinch plate has guide tubes symmetrically arranged on the side wall facing the gate body. The side wall of the assembly groove has a guide hole. The end of the guide tube relative to the anti-pinch plate extends into the guide hole. A first compression spring is provided between the anti-pinch plate and the inner wall of the assembly groove.

[0008] Furthermore, a first chamber for containing liquid medium is formed inside the anti-pinch plate, and a second chamber with a shape matching the guide tube is formed inside the guide tube. A notch is opened on the side wall of the first chamber to connect to the inside of the second chamber. A piston body is movably installed in the second chamber. A piston rod is provided on one side of the piston body opposite to the anti-pinch plate. The other end of the piston rod extends into the guide hole. A second compression spring is provided between the piston body and the inner wall of the second chamber.

[0009] Furthermore, each of the opposite side walls of the gate body is provided with a through hole that connects to the inside of the guide hole. The gate body is provided with an emergency stop mechanism for preventing the gate body from closing. The emergency stop mechanism includes a first connecting rod hinged to one end of the piston rod located inside the guide hole. A pin is provided in the through hole. A groove adapted to the pin is provided on the side wall of the first connecting rod.

[0010] Furthermore, the first connecting rod has a locking tooth on its side wall, and the opening has a protrusion on its side wall that matches the locking tooth. The locking tooth engages with the protrusion to prevent the gate body from closing.

[0011] Furthermore, the assembly groove is provided with first slide rails on both sides, and the anti-pinch plate is provided with pulleys adapted to the first slide rails.

[0012] Furthermore, the inner side of the gate body is equipped with a motor that drives the gate body to open and close, and the inner side of the gate body is provided with a second slide rail located directly above the opening. The gate sheath body is slidably mounted on the second slide rail, and a second connecting rod is hinged to one end of the gate body away from the anti-pinch plate and the motor. The other end of the second connecting rod is hinged to the gate sheath body.

[0013] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0014] This invention provides a turnstile with a gate sheath:

[0015] 1. An anti-pinch mechanism is provided. When the gate body closes and pinches a pedestrian, the anti-pinch plate deforms at the contact point, increasing the contact area and reducing the impact injury to the pedestrian. The liquid medium in the first chamber enters the second chamber through the notch, allowing the anti-pinch plate to deform further to reduce the injury.

[0016] Second, an emergency stop mechanism is provided. When the deformation of the anti-clamp plate causes the liquid medium in the first chamber to impact the piston body and move towards the inner side of the second chamber, the piston rod drives the first connecting rod to extend to the outside of the gate body. As the gate body continues to close, the connecting rod engages with the protrusion on the side of the opening, preventing the gate body from closing further and avoiding further damage.

[0017] Third, the gate sheath body is provided to rise and fall with the opening and closing of the gate body to close the gap formed between the gate body and the opening when the gate body is open, and to prevent foreign objects from entering the gate body and causing damage.

[0033] Please see Figures 1 to 6The present invention provides a turnstile with a gate sheath, comprising multiple turnstile bodies 1 spaced apart to form a passage, a gate body 2 for controlling the opening and closing of the passage within the turnstile body 1, an opening 12 on the side wall of the turnstile body 1 for accommodating the opening and closing of the gate body 2, and an anti-pinch mechanism at one end of the gate body 2 extending out of the turnstile body 1, the anti-pinch mechanism including an anti-pinch plate 3 movably mounted on the gate body 2 and capable of reciprocating movement, the anti-pinch plate 3 being a deformable, soft, elastic sealing material, when the gate body 2 closes and pinches a pedestrian, the anti-pinch plate 3 first contacts the pedestrian. The impact on the pedestrian's body causes deformation, increasing the contact area with the pedestrian's body and thus increasing the force-bearing area, thereby reducing the damage caused by the impact of the gate body 2 closing. The gate body 1 is provided with a gate sheath body 15 inside. The gate sheath body 15 moves up and down in the vertical direction with the opening and closing of the gate body 2 to open and close the opening 12. When the gate body 2 is open, the gate sheath body 15 is driven to descend and close the opening 12, which is formed by the gate body 2 retracting into the gate body 1. When the gate body 2 is closed, the gate sheath body 15 is driven to rise to avoid blocking the gate body 2.

[0034] like Figure 4 and Figure 5 As shown, a first chamber 31 for containing liquid medium is formed inside the anti-pinch plate 3, and a second chamber 33 corresponding to its shape is formed inside the guide tube 32. A notch 34 communicating with the inside of the second chamber 33 is opened on the side wall of the first chamber 31. A piston body 36 is movably installed in the second chamber 33. A piston rod 37 is provided on the side of the piston body 36 opposite to the anti-pinch plate 3. The other end of the piston rod 37 extends into the guide hole 23. A second compression spring 38 is provided between the piston body 36 and the inner wall of the second chamber 33. Under normal conditions, the second compression spring 38 presses against the anti-pinch plate 3. The piston body 36 closes the notch 34 to prevent the liquid medium in the first chamber 31 from entering the second chamber 33. When the gate body 2 closes and clamps the pedestrian, the part of the anti-pinch plate 3 that contacts the pedestrian's body deforms, applying pressure to the liquid medium in the first chamber 31. This causes the liquid medium to impact the piston body 36 and move into the second chamber 33. The liquid medium then enters the second chamber 33 through the notch 34, allowing the anti-pinch plate 3 to continue deforming to increase the contact area with the pedestrian's body and reduce the impact damage caused by the closing of the gate body 2.

[0035] like Figure 4 and Figure 5As shown, the gate body 2 extends out of the gate body 1 and has an assembly groove 21. The anti-pinch plate 3 is movably assembled in the assembly groove 21. The anti-pinch plate 3 has guide tubes 32 symmetrically arranged on the side wall facing the gate body 2. The side wall of the assembly groove 21 has a guide hole 23. The end of the guide tube 32 relative to the anti-pinch plate 3 extends into the guide hole 23. A first compression spring 35 is provided between the anti-pinch plate 3 and the inner wall of the assembly groove 21. Under normal conditions, the first compression spring 35 drives one end of the anti-pinch plate 3 to remain extended out of the assembly groove 21. When the gate body 2 closes and pinches a pedestrian, the anti-pinch plate 3 deforms under impact and slides inward into the assembly groove 21, further reducing the impact force on the pedestrian and reducing the damage caused by the gate body 2.

[0036] like Figure 3 and Figure 6 As shown, the gate body 2 has through holes 24 on its opposite sidewalls that connect to the inside of the guide hole 23. The gate body 2 is provided with an emergency stop mechanism to prevent the gate body 2 from closing. The emergency stop mechanism includes a first connecting rod 39 hinged to one end of the piston rod 37 located inside the guide hole 23. A pin 41 is provided in the through hole 24. A groove 40 adapted to the pin 41 is provided on the sidewall of the first connecting rod 39. The groove 40 cooperates with the pin 41 to restrict the rotation and extension path of the first connecting rod 39. A locking tooth is provided on the sidewall of the first connecting rod 39. A protrusion 13 adapted to the locking tooth is provided on the sidewall of the opening 12. The locking tooth engages with the protrusion 13 to prevent the gate body 2 from closing. When the gate body 2 closes and clamps a pedestrian, the anti-clamp plate 3 deforms, allowing the liquid medium in the first chamber 31 to enter the second chamber 33. This impacts the piston body 36, which moves inward into the second chamber 33, thereby driving the piston rod 37 to move. This, in turn, drives the two first connecting rods 39, which are hinged to the end of the piston rod 37 located inside the guide hole 23, to extend outward from the gate body 2 in an arc-shaped trajectory around the pin 41. As the gate body 2 continues to close, the first connecting rods 39 touch the side wall of the opening 12, and the locking teeth on the first connecting rods 39 engage with the protrusion 13, preventing the gate body 2 from continuing to close and avoiding further injury.

[0037] like Figure 5 As shown, the assembly groove 21 has a first slide rail 22 on both sides. The anti-pinch plate 3 is equipped with a pulley 42 that is compatible with the first slide rail 22. The pulley 42 works with the first slide rail 22 to make the anti-pinch plate 3 move inward into the assembly groove 21 under force, so that the sliding friction is changed into rolling friction. This allows the anti-pinch plate 3 to retract into the assembly groove 21 more quickly when under force, reducing the force between the anti-pinch plate 3 and the pedestrian, thereby reducing the injury to the pedestrian.

[0038] like Figure 2 and Figure 3As shown, a motor 11 is installed inside the gate body 1 to drive the gate body 2 to open and close. A second slide rail 14 is provided inside the gate body 1, located directly above the opening 12. The gate sheath body 15 is slidably mounted on the second slide rail 14. A second connecting rod 16 is hinged to one end of the gate body 2 away from the anti-pinch plate 3 and the motor 11. The other end of the second connecting rod 16 is hinged to the gate sheath body 15. When the gate body 2 is opened by the motor 11, as the gate body 2 flips and retracts into the gate body 1, the gate body 2 drives the gate sheath body 15 to slide downward along the second slide rail 14 through the second connecting rod 16. When the gate body 2 is completely retracted into the gate body 1, the gate sheath body 15 moves to the upper end of the opening 12, blocking the gap formed between the gate body 2 and the opening 12, preventing foreign objects from entering the gate body 1.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
