Description

Technical Field

[0001] The utility model relates to the technical field of access control bars, in particular to an access control bar of an access control system. Background Art

[0002] The access control system is a system used to control the entrance and exit channels, such as restricting the entry of vehicles without input information and releasing vehicles that have entered. At present, access control is mostly carried out by setting access control bars at the entrances and exits. The access control bars mostly include: gate bars, and bases that can drive the gate bars to rotate. Through the rotation drive of the base, the squeeze bar can block the entrance and exit channels or release the barrier state. However, when there is a problem with the base, such as power failure or damage to the drive structure, the squeeze bar located at the entrance and exit channels cannot release the barrier, which will affect vehicles that urgently need to enter or exit, causing partial traffic paralysis. The traditional solution is to destroy the gate bar or remove the gate bar. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide an access control bar of an access control system to solve the problem that when an emergency occurs in the base, the gate bar is difficult to release the blocked passage without being damaged.

[0012] When the lever part contacts the rod support, it is arranged vertically with the rod seat.

[0013] In some examples, the retracting mechanism is configured to drive the shift rod to rotate toward the base without being driven by the driving device and to separate from the rod support.

[0014] In some examples, the collection and transfer mechanism includes:

[0015] A winding chamber located on the rod seat;

[0016] A rotating shaft, which is rotatably connected between the rod seat and the winding chamber;

[0017] A pull rope connected to the gear lever and the rotating shaft portion in the reeling chamber;

[0018] A transmission member, which is located on the rotating shaft portion of the rod seat and is configured to: drive the rotating shaft to rotate between the rod seat and the winding chamber;

[0019] When the pull rope is gradually wound around the rotating shaft, the shift lever rotates relative to the lever seat.

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0035] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the utility model should be the common meanings understood by people with ordinary skills in the field to which the disclosure belongs. The "first", "second" and similar words used in the present disclosure do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing before the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0036] As can be understood from the foregoing description, in some scenarios, such as a residential community, it is necessary to set up access control bars at the entrance and exit of the community to restrict the entry of vehicles that do not belong to the community residents. The base is driven to allow the access control bar to cross at the entrance of the community to restrict vehicle entry.

[0037] However, as the service life of the base increases, problems may arise with the base 1. For example, a driving structure in the base 1 for driving the access control bar to rotate may be damaged, or a power outage may occur, making it impossible to raise the access control bar in a blocking state, resulting in vehicles near the entrance or exit being unable to pass or enter. This will cause a backlog of vehicles that continue to need to enter or exit, causing partial traffic paralysis. In this case, security personnel will often resort to destroying the gate bar or removing the gate bar to solve the problem.

[0038] In order to at least partially solve the above-mentioned problems and one or more of other potential problems, an exemplary embodiment of the utility model proposes an access control rod of an access control system, by designing a gate rod 2 to be composed of two sections, namely, a rod seat 21 and a gear rod 22, and providing a retracting mechanism 3 between the gear rod 22 and the rod seat 21 to connect them. In normal use, the gate rod 2 as a whole can be rotated based on the base 1 to release or restrict the entry of vehicles. When there is a problem with the base 1, the retracting mechanism 3 can be used to allow the gear rod 22 to rotate based on the rod seat 21, so that the gear rod 22, which originally needed to be destroyed or removed before being released, can now be rotated and raised without being destroyed or disassembled.

[0039] The following combination Figure 1-Figure 4 The access control lever of this access control system is exemplified. Figure 1 It is a plan view of the utility model in which the gate rod as a whole is switched between blocking and releasing states based on the rotation of a base. Figure 2 It is a schematic plan view of the state switching between the blocking state and the passing state based on the rotation of the lever 22 of the gate lever 2 of the utility model based on the lever seat 21. Figure 3 It is a schematic diagram comparing the top view and the front view of the gate rod 2 of the utility model. Figure 4 Schematic diagram of the retracting mechanism 3 in some examples of the present invention; the access control lever of the access control system includes a base 1, a gate lever 2 and a retracting mechanism 3; wherein the base 1 is used to drive the gate lever 2 to rotate; the gate lever 2 is connected to the base 1 and is used to rotate toward the base 1 or away from the base 1 to rise or fall under the drive of the base 1.

[0040] Regarding the base 1, a driving device is installed inside the base 1. The driving device has an output shaft and protrudes from the base 1. One end of the gate rod is fixedly connected to the output shaft on the base 1, and the driving device is configured to: drive the gate rod 2 to rotate so that the gate rod 2 can be blocked laterally at the entrance or exit or be released from the entrance or exit.

[0041] In some instances, the driving device includes: an electric cylinder, a gear and a rack, wherein the rack is connected to the telescopic shaft of the electric cylinder, and the gear is fixed on the output shaft and meshes with the rack, and the electric cylinder drives the rack to move linearly to drive the gear to rotate, so that the output shaft rotates, so that the gate rod 2 rotates.

[0042] In some examples, the driving device includes: a decelerating rotating component, such as a reduction motor, the shaft of which is connected to the output shaft via a coupling. In this case, the output shaft is an extended shaft, which is driven by the reduction motor to rotate so that the gate rod 2 rotates.

[0043] Regarding the gate rod 2, it includes a rod seat 21 connected to the base 1, and a lever 22 rotatably connected to the rod seat 21. The length ratio of the rod seat 21 to the lever 22 is between 1:6 and 8, and the preferred length ratio is 1:7.

[0044] The two-stage design of the gate rod 2 allows the lever 22 to rotate based on the rod seat 21 in some cases, such as when the internal drive device of the base is damaged, so that the lever 22 rises.

[0045] Furthermore, one end of the rod seat 21 is transmission connected to the driving device, and the other end is integrally formed with a rod support 211; when the gear rod 21 partially contacts the rod support 211, it is arranged vertically with the rod seat 21, and the rod support 211 is used to limit the gear rod 21 from continuing to rotate toward the bottom end of the rod seat 21.

[0046] Regarding the retracting mechanism 3, it is arranged between the rod seat 21 and the gear rod 22, and is configured to: drive the gear rod 22 to rotate relative to the rod seat 21. Specifically, the retracting mechanism 3 can drive the gear rod 22 to rotate toward the base 1 without being driven by the driving device, away from the rod support 211.

[0047] Furthermore, the winding and rotating mechanism 3 includes: a winding chamber 31, which is located on the rod seat 21; a rotating shaft 32, which is rotatably connected between the rod seat 21 and the winding chamber 31; a pull rope 33, which is connected to the gear lever 22 and the rotating shaft 32 part in the winding chamber 31; a transmission member 34, which is located on the rotating shaft 32 part of the rod seat 21 and is configured to: drive the rotating shaft 32 to rotate between the rod seat 21 and the winding chamber 31; when the pull rope 33 is gradually wound around the rotating shaft 32, the gear lever 22 rotates relative to the rod seat 21. When in use, torque is provided to the rotating shaft 32 through the transmission member 34 to make the rotating shaft 32 rotate, and the pull rope 33 fixed on the rotating shaft 32 is gradually wound around the rotating shaft 32 as the rotating shaft 32 rotates, and the length of the pull rope 33 is shortened, and the lower lever 22 is pulled by the pull rope 33 to rotate and rise toward the rod seat 21. It should be noted that: under this drive, it is best to push the lever 22 upward before the lever 22 rotates and rises, so that the pull rope 22 can better pull the lever 22 to rotate.

[0048] In some embodiments, the transmission member 34 is a crank, and the crank is manually cranked to provide torque to the rotating shaft 32 .

[0049] In some examples, the transmission member 34 is a motor, a pneumatic or hydraulic rotary cylinder, and the motor, the pneumatic or hydraulic rotary cylinder is controlled to start providing torque to the rotating shaft 32 .

[0050] In some examples, a reverse rotation prevention structure 4 is further included to limit the directional rotation of the rotating shaft 32 . When the gate rod 2 is used as a door access control rod, the stop rod 22 of the gate rod 2 is not easily rotated based on the rod seat 21 under the action of the reverse rotation prevention structure 4 .

[0051] Furthermore, the anti-reverse structure 4 includes: a ratchet 41, which is located on the rotating shaft 32 of the rod seat 21; a pawl 42, which is located on one side of the ratchet 41 through a torsion spring and engages with the ratchet 41, and is used to continuously engage with the ratchet teeth of the ratchet 41 as the ratchet 41 rotates in the reverse direction; when the ratchet 41 rotates and the pawl 42 is moved, the pull rope 33 is gradually wound around the rotating shaft 32 of the winding chamber 31; when the pawl 42 is disengaged from the ratchet teeth of the ratchet 41, the ratchet 41 can rotate forward. When in use, the winding rope 22 of the rotating shaft 32 will drive the ratchet 41 to rotate (in the reverse direction, i.e., counterclockwise), and drive the pawl 42 to rotate upward under the torsion spring (not shown in the figure), and then reset under the action of the torsion spring, that is, the pawl 42 is disengaged from one ratchet tooth of the ratchet 42 and then meshes with another ratchet tooth, that is, the cooperation of the ratchet 41 and the pawl 42 in this state will not limit the rotation of the rotating shaft 32, thereby limiting any angle of rotation of the gear lever 22 based on the rod seat 21. However, when the rotating shaft 32 rotates clockwise, the special cooperation of the ratchet 41 and the pawl 42 will limit the rotation of the rotating shaft 32. When the rotating shaft 32 needs to rotate clockwise and the gear lever 22 is reset to the straight state with the rod seat 21, the pawl 42 can be pressed under the action of the torsion spring to move away from one end of the ratchet 41, so that the pawl 42 is disengaged from the ratchet 41 and does not contact the ratchet 41, and the rotating shaft 32 can be rotated clockwise without restriction.

Under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
