[0002] Parking lot barriers are key equipment for managing the entry and exit of vehicles in parking lots. They are usually installed at the entrance and exit of parking lots to intercept and release vehicles.
[0003] The gate bars of many parking lots are relatively long, which results in a longer torque during operation. The rotating parts need to bear a greater force, especially the matching parts on the gate bars. At the same time, due to some cases of bar breaking and malicious damage, the gate bars are often damaged and need to be replaced. Therefore, the gate bars need to be able to be replaced separately. The existing gate bar installation structure is relatively complicated and requires the removal of multiple fixing screws, which is inconvenient to disassemble. Utility Model Content

[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.
[0022] As attached Figure 1-5 As shown, the utility model discloses a parking lot barrier structure, including a box body 1 fixed on the ground for installing relevant equipment, a driving device arranged inside the box body 1, a gate rod driving shaft transmission-connected with the driving device, and a gate rod 2 installed on the gate rod driving shaft, the gate rod driving shaft includes a connecting section 5, a mounting section 4 and a locking section 3 with successively decreasing outer diameters, the locking section is a threaded rod, and an anti-loosening nut is provided on the locking section. When the gate rod is damaged and needs to be replaced, the anti-loosening nut can be loosened to facilitate replacement, and the anti-loosening nut has its own anti-loosening function, and will not be accidentally disengaged in daily use.
[0023] The length of the mounting section 4 is smaller than the width of the gate rod 2, so that after the anti-loosening nut is installed in place, the inner side of the anti-loosening nut can support the side wall of the gate rod 2. When the gate rod driving shaft rotates, the anti-loosening nut can provide a certain force to share the force between the gate rod 2 and the mounting section 4 when the gate rod 2 moves, thereby reducing the probability of damage to the connection position between the gate rod 2 and the gate rod driving shaft.
[0024] The utility model also provides a structure of a locking nut, including a nut A and a nut B installed on the locking section 3 and cooperating with each other, wherein the nut A is in the shape of a convex nut, including an assembly section A7 and a cooperating section 8 located on one side of the assembly section A7, and threaded holes are provided on the assembly section A7 and the cooperating section 8 for cooperating with the external thread on the locking section 3, and the nut B is in the shape of a concave nut, including an assembly section B6 and a cooperating hole 10, and a threaded hole is also provided on the assembly section B6 for connecting with the locking section 3. The outer wall of the cooperating section 8 is in the shape of a frustum, and the cooperating hole 10 is eccentrically arranged with respect to the axis of the cooperating section 8. Preferably, the cooperating section 8 adopts an eccentric design and is eccentrically processed so that the cooperating section 8 plays the role of a wedge, and the cooperating hole 10 is not eccentrically processed, and the loosening problem can be effectively solved when the nut A and the nut B are matched.
[0025] Preferably, an anti-slip washer 9 is provided between the gate rod 2 and the nut A.
[0026] The utility model also discloses a connection structure between a gate rod 2 and a mounting section 4. Specifically, a connection protrusion 19 protruding outward is provided on the mounting section 4. One side of the cross section of the connection protrusion 19 is a plane and perpendicular to the rotation direction, and the other side is arc-shaped and smoothly transitions with the outer wall of the mounting section 4. An assembly hole matching the mounting section 4 and the connection protrusion 19 is provided on the gate rod 2. Preferably, when the gate rod 2 is in a horizontal state, one side of the plane of the connection protrusion 19 faces upward and is in a horizontal state, or is in a slightly downward tilted state, so that the plane of the connection protrusion 19 is a force-bearing surface, and force is applied to the gate rod, and the arc-shaped surface on the other side is used as a supporting surface for support. The special structure of the connection protrusion 19 ensures the force-applying contact surface with the gate rod 2 on the one hand, and ensures that the connection protrusion 19 will not be easily damaged on the other hand, thereby ensuring the service life of the gate rod 2 at the matching position with the mounting section 4.
[0027] In daily use, the gate rod 2 is in a horizontally closed state for a long time, and will only be deflected upward to open when a vehicle passes. Therefore, the connection position between the gate rod 2 and the gate rod driving shaft is in a state of large torque for a long time. In order to alleviate this situation, a supporting device is added to the box body 1 and located in front of the gate rod driving shaft, including a support plate 11 fixedly mounted on the box body 1 and a bracket 12 arranged on the support plate 11. After the gate rod 2 falls, it is located in the bracket 12, and the supporting device can play a lifting role. When the gate rod 2 falls, the torque between the gate rod 2 and the gate rod driving shaft can be reduced, thereby further reducing the probability of damage at the connection position between the two.
[0028] Preferably, a buffer plate 13 is provided in the bracket 12, and the shape of the buffer plate 13 corresponds to the shape of the bracket 12. A spring 14 is provided between the buffer plate 13 and the bracket 12, which can play a buffering role after the gate rod 2 falls and reduce collision.
[0029] The driving device includes a motor 15, a reduction gear box, a first connecting rod 16, a second connecting rod 17 and a third connecting rod 18. One end of the first connecting rod 16 is connected to the output shaft of the reduction gear box, and the third connecting rod 18 is connected to the gate rod driving shaft. The two ends of the second connecting rod 17 are respectively connected to the third connecting rod 18 and the first connecting rod 16 through a rotating shaft. The gate rod driving shaft is driven by the connecting rod structure. This driving device structure has been widely embodied in existing barriers and will not be repeated here.
[0030] The utility model utilizes a new anti-loosening bolt structure to lock the gate rod, and can also facilitate quick disassembly and assembly of the gate rod. At the same time, the connection form between the gate rod 2 and the gate rod connecting shaft is improved, and a supporting device is added in front of the gate rod connecting shaft, which can effectively reduce the probability of damage at the connection position between the gate rod and the gate rod driving shaft and improve the service life.
[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features thereof may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
