TECHNICAL FIELD
[0001] The utility model belongs to motor vehicle parking management equipment technical field, concretely relates to a telescopic folding rod. BACKGROUND
[0002] With the acceleration of urbanization, the number of motor vehicles is increasing rapidly, and the management demand of special parking spaces (such as charging parking spaces, barrier-free parking spaces, logistics loading and unloading parking spaces, etc.) is increasingly urgent. Traditional parking space management relies on manual attendance or simple roadblock facilities, but there are problems such as low efficiency, easy occupation, and inability to realize real-time control. In recent years, the rear post rod type parking space controller has become the mainstream technical scheme, which installs a fixed host in the rear of the parking space, extends a foldable post rod to the parking space direction, and realizes the automatic management of the parking space by combining mechanical blocking with electronic control. Such equipment is usually composed of a transmission mechanism (such as a motor drive), a folding rod assembly and an intelligent control system (such as license plate recognition, remote control).
[0003] However, the existing folding rod design has the following significant defects:
[0004] 1. When the folding rod is in the flat state (blocking state: the front end is equipped with a cross rod), if the vehicle misoperates or forcibly enters, directly impacts the rod body, the rigidly connected front rod and rear rod will transmit the impact force to the transmission mechanism, causing damage to key components such as gears and motors, and even causing permanent deformation of the rod body.
[0005] 2. Due to the frequent impact of the folding rod, the equipment failure rate is high, and the transmission parts need to be replaced regularly or the rod body structure needs to be corrected, which significantly increases the maintenance cost. Some public places (such as logistics parks and charging stations) have large traffic flow and complex operating environment, and the average service life of the equipment is less than one year, which seriously restricts the promotion of special parking spaces.
[0006] 3. The fixed length design of the existing folding rod is difficult to adapt to different parking space sizes, for example, narrower parking spaces require shorter folding rods, and the traditional scheme needs to be customized, which leads to insufficient deployment flexibility. SUMMARY
[0007] The utility model aims at providing a telescopic folding rod to solve the problems raised in the background.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a telescopic folding rod, comprising a pull rod, a front rod, a rear rod and a pull rod connecting piece;
[0009] One end of the rear rod is connected with the equipment transmission mechanism, and the other end is connected with the pull rod and the front rod through the pull rod connecting piece;
[0010] The pull rod connecting piece includes a front rod guide tube, a guide clamp plate and an inclined plate, the guide clamp plate and the inclined plate are arranged on both sides of the sliding groove bottom plate, the pull rod connecting piece is fixedly connected with the pull rod and the rear rod, and is sleeved on the front rod, when the front rod is subjected to external force, the front rod moves backward along the guide of the sliding groove bottom plate to eliminate the influence of the external force on the rear rod.
[0011] Preferably, limit blocks are arranged at both ends of the front rod.
[0012] Preferably, the material of the pull rod, the front rod, the rear rod and the pull rod connecting piece is high-strength aluminum alloy.
[0013] Preferably, the included angle between the inclined plate of the pull rod connecting piece and the sliding groove bottom plate is 30° to 60°.
[0014] Preferably, the lengths of the front rod and the rear rod are adjustable to adapt to the size requirements of different parking spaces.
[0015] Preferably, anti-skid lines are arranged on the guide clamp plate of the pull rod connecting piece to increase the friction force with the front rod and prevent deviation during sliding.
[0016] The technical effects and advantages of the utility model are as follows:
[0017] 1. Anti-collision protection: through the staggered design of the front rod and the rear rod, the front rod and the pull rod connecting piece are connected through interference fit, can slide backward when subjected to external impact, effectively absorbs and offsets the impact force, avoids the direct conduction of the impact force to the rear rod and the transmission mechanism, thereby protecting the key components such as the motor and the gear from damage, prolonging the service life of the equipment.
[0018] 2. Precise control of folding trajectory: the guide clamp plate and the inclined plate in the pull rod connecting piece can precisely control the sliding trajectory of the front rod, ensure that the folding rod moves stably during unfolding and folding, and avoid deviation or jamming problems caused by uneven force.
[0019] 3. Adjustable length: the lengths of the front rod and the rear rod can be adjusted according to the actual size of the parking space, adapt to the needs of different scenes, improve the flexibility and applicability of the equipment, and avoid the limitations brought by the traditional fixed length design.
[0020] 4. Low maintenance cost: since the front rod can slide to absorb the impact force, the damage probability of the transmission mechanism and the rod body is reduced, the failure rate and maintenance cost of the equipment are reduced, and it is especially suitable for public places with large traffic flow and complex operating environment.
[0021] 5. Simple structure and convenient installation: the utility model adopts high-strength aluminum alloy material, which is light and firm, and is easy to install and maintain, and can be quickly deployed on various special parking spaces (such as charging parking spaces, barrier-free parking spaces, etc.).
