The traditional barrier gate often lacks effective supporting structure when it is put down, which may be displaced due to external force and affect the safety. Due to the poor meshing between the gears and the lack of effective damping measures, the traditional barrier gate will produce a lot of noise in the lifting process. UTILITY MODEL CONTENTS

[0005] Therefore, the mechanical parking lot barrier gate structure provided by the utility model solves the problem that the traditional parking lot barrier gate is prone to wear in the long-term use process, and improves the service life and stability of the barrier gate.

[0006] The utility model is implemented as follows:

[0007] The utility model provides a kind of mechanical parking lot barrier structure, including main part, the main part top side is fixedly arranged with lever arm, one end of the lever arm passes through the main part and is arranged in the main part interior, the outside of the lever arm movably is provided with fixed barrel, it is connected between the fixed barrel and lever arm by several bearings, recess is opened in the main part interior top end, wherein, the lever arm is connected with driving gear, the lever arm bottom is equipped with support foot, driving gear is fixedly arranged in the recess interior outside the fixed barrel, the support foot is used to provide support when the lever arm is put down, the driving gear tooth profile is conical, the driving gear has involute tooth profile, the pitch of dedendum to addendum gradually becomes smaller, the driving gear includes first gear and second gear, the support foot longitudinal section is V-shaped;The lever arm is connected between the driving gear by center shaft, the axis of the center shaft and the axis of the driving gear intersect at a point;The connection of the driving gear and the center shaft is equipped with anti-loosening device, both ends of the lever arm are equipped with buffer device, for providing buffering action when the lever arm moves left and right.

[0008] Conical driving gear can improve power transmission efficiency and reduce energy loss.

[0009] Effective connection of lever arm and conical driving gear ensures smooth lifting of lever arm and improves service life of equipment.

[0010] V-shaped support foot can provide stable support when the lever arm is put down, improve the stability of overall structure, and ensure safety.

[0011] On the basis of the above technical scheme, the mechanical parking lot barrier structure of the utility model can be further improved as follows:

[0012] Among them, the support foot has one or more, and the lever arm contacts the ground through the support foot.

[0013] Further, the included angle of the two V-shaped legs of the support foot is 30° to 60°.

[0014] The included angle of the V-shaped support foot is between 30° and 60°, which can effectively disperse the ground reaction force when the lever arm is put down and improve the stability of the support foot.

[0015] Such an included angle range can ensure that the support foot has good support effect under different ground conditions, improve the adaptability and safety of the overall structure.

[0016] Further, the connection point of the support foot and the lever arm is located within 1 / 3 to 1 / 2 of the length of the lever arm bottom, and the ratio between the length of the lever arm and the spread width of the support foot is 3:1 to 5:1.

[0017] The beneficial effect of the above improvement scheme is that the support leg connecting point is arranged in the range of 1 / 3 to 1 / 2 of the length of the bottom of the lever arm, which can ensure that the support leg can provide the best support effect when the lever arm is put down, thereby improving the stability and safety of the device.

[0018] This connection position can ensure that the support leg can play a good supporting role on the lever arm of different lengths.

[0019] Further, the tooth shape of the driving gear is from narrow to wide from the dedendum to the addendum.

[0020] The beneficial effect of the above improvement scheme is that through this special tooth shape design, the contact area of the tapered driving gear gradually increases from the dedendum to the addendum when it meshes with the meshing gear, thereby distributing more load on the entire contact surface, reducing local stress concentration, and further reducing wear. Since the addendum part is wider, the contact area increases significantly when it contacts the dedendum part of the corresponding meshing gear. Compared with the traditional circular gear, the contact area can be increased by 20% to 50%. The special tooth shape design of the tapered driving gear makes the pressure distribution on the entire contact surface more uniform, reduces the situation of excessive local pressure, and thereby improves the service life of the gear.

[0023] Further, the taper of the driving gear is 1:20 to 1:10.

[0024] The beneficial effect of the above improvement scheme is that the special tooth shape design of the tapered driving gear can increase the contact area, reduce local stress concentration, and improve the service life of the gear.

[0025] The larger contact area can ensure more stable power transmission and reduce gear wear.

[0026] Further, the two V-shaped legs of the support leg extend vertically from the bottom of the lever arm to both sides, perpendicular to the length direction of the lever arm.

[0027] When the V-shaped support feet extend perpendicular to the length direction of the lever arm, the fulcrum distribution of the two support feet can be ensured on both sides of the bottom of the lever arm, forming a stable triangular support area.

[0028] Further, the main body is further provided with a motor, and the driving gear is connected with the motor through a shaft coupling for transmitting rotary power.

[0029] The shaft coupling can absorb axial, radial and angular deviations, ensuring smooth power transmission between the motor and the conical driving gear.

[0030] This connection mode can reduce vibration and noise during power transmission and improve the overall operation efficiency of the equipment.

[0031] Compared with the prior art, the mechanical parking lot barrier gate structure has the following advantages:

[0032] Improving the service life:

[0033] Conical driving gear: the conical driving gear replaces the traditional circular gear, which has an involute tooth profile, and the tooth pitch from the root to the top gradually decreases.

[0036] V-shaped support feet: the V-shaped support feet are installed at the bottom of the lever arm, with an included angle of 30° to 60°, which can effectively disperse the ground reaction force and improve stability;

[0038] Reducing noise:

[0039] Taper of conical driving gear: the taper of the conical driving gear is 1:20 to 1:10, ensuring smooth transmission and reducing noise;

[0040] Bearing and coupling: bearings are provided at the connection between the central shaft and the lever arm to reduce friction loss; a flexible coupling is used to connect the conical drive gear and the motor to absorb axial, radial and angular deviations, reduce vibration and noise;

[0041] Reduced maintenance cost:
