Description

Technical Field

[0001] The present invention belongs to the technical field of security gates, and particularly relates to a turnstile - type security gate. Background Art

[0002] A security gate is a detection device for detecting whether a person is carrying metal items, also known as a metal detection gate. Metal detection security gates are mainly used in public places with large crowds such as airports, railway stations, and large - scale conferences to check for metal items hidden on a person's body.

[0003] When a traditional security gate is in use, it is not provided with an interception structure, and thus cannot control the entry and exit of people. For example, Chinese invention CN114167513A discloses an Internet - of - Things intelligent security gate. By pushing the railing to an appropriate opening, people can freely pass between the two railings; when it is detected that a person has hidden metal on their body or has an abnormal body temperature, the limiting mechanism directly limits the rotation shaft, so that people cannot push the railing to intercept and prevent people from passing through the door frame.

[0004] However, in the above - mentioned technical solution, four railings are connected by a rotating shaft and need to drive the four railings to rotate. Therefore, the overall volume is relatively large, which increases the overall occupied space of the security gate with turnstile function, resulting in inconvenient installation of the security gate and limited use space, and poor overall adaptability. Summary of the Invention

[0005] The purpose of the present invention is to provide a turnstile - type security gate. By driving a slide bar to rotate through a transmission shaft, and using a follower to cooperate with a cam groove, the slider moves along the length direction of the slide bar, and drives an incomplete gear to rotate through a rack, so as to realize the switching of the gate rod between the horizontal state and the vertical state, and solve the problems of inconvenient installation and poor adaptability of the existing security gates.

[0006] To solve the above - mentioned technical problems, the present invention is realized through the following technical solutions:

[0007] The present invention relates to a turnstile - type security gate, which comprises two detection door bodies. An installation plate is fixedly connected to the side surface of the detection door body, and a fixed sleeve and a driving device are fixedly connected to the installation plate; A transmission shaft is rotatably connected in the fixed sleeve, a disc is fixedly connected to the outer wall of the fixed sleeve, and a cam groove is formed on the lower surface of the disc; The upper end of the transmission shaft is in transmission connection with the driving device, and a plurality of sliding strips are fixedly connected to the lower end. The plurality of sliding strips are uniformly arranged along the circumferential direction of the transmission shaft, and a single sliding strip is arranged along the radial direction of the transmission shaft; The sliding strip is rotatably connected with an incomplete gear and slidably connected with a slider. The incomplete gear is connected with a gate rod. The slider is fixedly connected with a rack meshing with the incomplete gear and a follower cooperating with the cam groove, so as to drive the sliding strip to rotate through the transmission shaft, enable the slider to move along the length direction of the sliding strip, and drive the incomplete gear to rotate through the rack, so as to realize the switching of the gate rod between the horizontal state and the vertical state.

[0008] As a preferred technical solution of the present invention, the fixed sleeve is fixedly connected to the lower surface of the installation plate, and the driving device is fixedly connected to the upper surface of the installation plate.

[0009] As a preferred technical solution of the present invention, a driven wheel is fixedly connected to the upper end of the transmission shaft for transmission connection with the driving device through the driven wheel, and a cover plate is fixedly connected to the upper surface of the installation plate for hermetically protecting the driven wheel and the driving device through the cover plate.

[0010] As a preferred technical solution of the present invention, a dovetail groove is formed on the lower surface of the slider; The upper side of the sliding strip is adapted to the dovetail groove.

[0011] As a preferred technical solution of the present invention, the rack is fixed to the inner top surface of the dovetail groove; An avoidance groove corresponding to the rack is formed on the upper surface of the sliding strip, a through notch is formed on the bottom surface of the avoidance groove, and the incomplete gear is rotatably connected in the through notch.

[0012] As a preferred technical solution of the present invention, the gate rod comprises a connecting rod connected with the incomplete gear and an intercepting rod connected with the connecting rod, and the intercepting rod is a hollow tubular structure.

[0013] As a preferred technical solution of the present invention, the number of the sliding strips is two or four. When one of the sliding strips rotates to face the passage between the two detection door bodies and is perpendicular to the pedestrian direction, the gate rod connected to this sliding strip is in the horizontal state, and the remaining gate rods are in the vertical state.

[0014] As a preferred technical solution of the present invention, the disc is connected with a protective cover plate for protecting the disc and the sliding strip through the protective cover plate.

[0015] The present invention has the following beneficial effects:

[0016] In the present invention, a transmission shaft drives a slide bar to rotate. The follower on the slide bar cooperates with the cam groove of the disc, so that during the rotation process, the slider moves along the length direction of the slide bar, and drives an incomplete gear to rotate through a rack, realizing the switching of the gate rod between the horizontal state and the vertical state, making the gate rod that is not in the intercept position in the vertical state, thereby effectively reducing the overall volume and occupied space of the security inspection door, which is beneficial to improving the overall installation convenience and adaptability to the installation space.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0030] Embodiment 1

[0031] Please refer to Figure 1 As shown, the present invention is a turnstile - type security inspection door, including two detection door bodies 1. A mounting plate 11 is fixedly connected to the side surface of the detection door body 1. The mounting plate 11 is fixedly connected with a fixed sleeve 101 and a driving device 102. A transmission shaft 2 is rotatably connected in the fixed sleeve 101.

[0032] Among them, the upper end of the fixed sleeve 101 is fixedly connected to the lower surface of the mounting plate 11 through a flange and screws. The driving device 102 is fixedly connected to the upper surface of the mounting plate 11. The driving device 102 is a motor connected with a gear.

[0033] The upper end of the transmission shaft 2 penetrates through the mounting plate 11 and is fixedly connected with a driven wheel 204. The driven wheel 204 meshes with the gear of the motor, and is used for driving connection between the transmission shaft 2 and the driving device 102 through the driven wheel 204 to realize the transmission connection between the transmission shaft 2 and the driving device 102. And a cover plate is connected to the upper surface of the mounting plate 11 through screws, and is used for enclosing and protecting the driven wheel 204 and the driving device 102 through the cover plate.

[0034] As Figure 2 and 3As shown, a disc 103 is welded or screw-connected to the outer wall of the fixed sleeve 101, and a cam groove 104 is provided on the lower surface of the disc. The lower end of the transmission shaft 2 extends out of the fixed sleeve 101 and is fixedly connected with two or four sliding strips 201. Taking four as an example as shown in the figure, the four sliding strips 201 are evenly arranged along the circumferential direction of the transmission shaft 2, and a single sliding strip 201 is arranged along the radial direction of the transmission shaft 2.

[0035] As Figure 3 and 4 As shown, the sliding strip 201 is rotatably connected with an incomplete gear 3 and slidably connected with a slider 4. The incomplete gear 3 is connected with a brake rod 301. The slider 4 is fixedly connected with a rack 401 meshing with the incomplete gear 3 and a follower 402 cooperating with the cam groove 104, which is used to drive the transmission shaft 2 to rotate through the driving device 102. The transmission shaft 2 drives the four sliding strips 201 to rotate. Since the position of the disc 103 is fixed, when the sliding strip 201 drives the slider 4 to rotate circumferentially, the follower 402 cooperates with the cam groove 104, so that the slider 4 moves along the length direction of the sliding strip 201 while rotating circumferentially. The slider 4 moves, thereby driving the incomplete gear 3 to rotate through the rack 401, realizing the switching of the brake rod 301 between the horizontal state and the vertical state.

[0036] Specifically, as Figure 1 , 3 and 5 shown, when one of the sliding strips 201 rotates to face the passage between the two detection door bodies 1 and is perpendicular to the pedestrian direction, the follower 402 on the slider 4 is restricted by the cam groove 104, so that the slider 4 is moved to the end of the sliding strip 201 connected to the transmission shaft 2. Thus, during the movement, the incomplete gear 3 is driven to rotate counterclockwise through the rack 401, so that the brake rod 301 gradually changes from the original vertical state to the horizontal state, so that the brake rod 301 connected to this sliding strip 201 is in the horizontal state, realizing the interception of the personnel passing between the two detection door bodies 1 by using the brake rod 301.

[0037] Moreover, for the original brake rod 301 in the horizontal state, during the rotation of the transmission shaft 2, the cam groove 104 pushes the slider 4 to move towards the end of the sliding strip 201 away from the transmission shaft 2, thereby driving the incomplete gear 3 to rotate through the rack 401, so that the incomplete gear 3 drives the brake rod 301 to change from the horizontal state to the vertical state.

[0038] As for the four brake rods 301 in the figure, each time the transmission shaft 2 rotates 90°, the brake rod 301 completes a position exchange, so that one of the brake rods 301 is in the horizontal state, that is, in the interception position, and the other three brake rods 301 not in the interception position are in the vertical state. Thus, the overall volume is reduced, effectively reducing the overall volume and occupied space of the security inspection door, facilitating flexible installation and use in places with limited space, which is conducive to improving the overall installation convenience and adaptability to the installation space.

[0039] Example Two

[0040] On the basis of Example One, a dovetail groove is formed on the lower surface of the slider 4; the upper side of the slide bar 201 is adapted to the dovetail groove to realize the sliding connection between the slider 4 and the slide bar 201. At the same time, the rack 401 is fixed to the inner top surface of the dovetail groove by screws.

[0041] An avoidance groove 202 corresponding to the rack 401 is formed on the upper surface of the slide bar 201 to prevent interference between the rack 401 and the slide bar 201. A through groove 203 is formed on the inner bottom surface of the avoidance groove 202, and the incomplete gear 3 is rotatably connected to the through groove 203. Wherein, a through hole penetrating through the through groove 203 is formed on the side surface of the slide bar 201, a rotating shaft is inserted into the through hole, and the rotating shaft is rotatably connected to the incomplete gear 3 to realize the installation of the incomplete gear 3 in the through groove 203.

[0042] By installing the rack 401 on the inner top surface of the dovetail groove and installing the incomplete gear 3 in the through groove 203, the volume of the whole assembly of the slider 4, the slide bar 201 and the incomplete gear 3 is reduced, so that the overall structure is more compact, which is beneficial to reducing the overall volume.

[0043] Example Three

[0044] On the basis of Example One or Example Two, as Figure 3 and 7 shown, the brake rod 301 includes a connecting rod 302 connected to the incomplete gear 3, and an intercepting rod 303 connected to the connecting rod 302, and the intercepting rod 303 is a hollow tubular structure.

[0045] The connecting rod 302 can be welded to the incomplete gear 3, and the intercepting rod 303 and the connecting rod 302 can be connected by threads or by screws to realize the detachable connection between the intercepting rod 303 and the connecting rod 302, so that the intercepting rod 303 with different lengths can be flexibly replaced to adapt to the use on security gates with different widths. By setting the intercepting rod 303 as a hollow tubular structure, the weight of the intercepting rod 303 is reduced, which is beneficial to improving the reliability and stability of use.

[0046] At the same time, as Figure 1 shown, a protective cover plate 105 is connected to the disc 103 by screws to protect the disc 103 and the slide bar 201 through the protective cover plate 105, which is beneficial to improving the overall aesthetics, and at the same time avoids the situation of foreign objects being entangled, which is beneficial to improving the overall use safety.
