Description

Hidden type turnover hurdle for plastic track

Technical Field

The invention relates to the technical field of sports equipment, in particular to a hidden type overturning hurdle for plastic runways.

Background

The plastic track is an indispensable important facility in modern track and field areas, compared with the traditional soil track, the plastic track has the advantages of good elasticity, skid resistance, wear resistance, shock absorption, easy field nursing, bright color, attractive appearance, orderliness and the like, so the plastic track is adopted by various track and field areas, including the playground of , middle school and primary school, is widely used at .

Disclosure of Invention

The technical problem to be solved by the invention is to provide improved hidden turnover hurdles for plastic runways in order to solve the problems in the background art, and solve the problems that the traditional hurdles are simple in structure, time and labor are wasted, the function list is troublesome to put and occupies a large space when needing to put again.

The technical scheme includes that the hidden type overturning hurdle for plastic runways comprises a plastic runway and a hurdle body, wherein an overturning accommodating groove, an extruding accommodating groove and an overturning control groove are formed in the upper surface of the plastic runway, corresponding to the position of the hurdle body, the lower end of the hurdle body is movably connected with the inner side wall of the overturning control groove through a connecting rotating shaft, a low-speed high-torque motor is fixedly connected to the lower end of the inner side wall of the overturning control groove, an upper transmission gear surface is arranged on the outer arc surface of the connecting end of the hurdle body, a transmission gear meshed with the upper transmission gear surface is fixedly connected to the rotating shaft on the front side of the low-speed high-torque motor, the hurdle body is driven to overturn along the connecting rotating shaft through the low-speed high-torque motor, an extrusion plate is arranged in the extruding accommodating groove, the lower end of the extrusion plate is connected with the extruding accommodating groove surface through a compression spring, a transmission groove is transversely formed in the plastic runway, a transmission groove is movably connected to a transmission plate, the lower surface of the locking plate is meshed with the locking gear on the back side of the low-speed high-torque motor, and the locking plate is fixedly connected with the extrusion plate through a locking groove, and the locking plate is fixedly connected with the extrusion plate.

Preferably, in order to improve the waterproof and dust-proof performance, the cross section of the extrusion plate is the same as that of the extrusion accommodating groove.

Preferably, the diameter of the transmission gear is larger than that of the locking gear for improving the torque.

Preferably, in order to improve the transmission efficiency, the turnover accommodating groove and the transmission groove are parallel to each other.

The hidden overturning hurdle for the plastic runways has the advantages that the hidden overturning hurdle is driven by a low-speed high-torque motor in the overturning control groove and matched with the transmission gear to overturn on the plastic runways along the connecting rotating shaft, so that the hurdle can be overturned and lifted from the plastic runways when in use, can be overturned and stored into the overturning storage groove and the extruding storage groove when not in use, drives the transmission locking plate to translate in the transmission groove while overturning, and upwards fills the extruding storage groove by matching the compression spring with the locking groove in a separating way, so that the surface flatness and the safety of the runways are improved.
