Description

TECHNICAL FIELD

[0002] The buried parking stall lock is a mechanical device installed on the ground to prevent others from occupying the parking stall, and is prior art. For example, a ground parking stall lock disclosed in Chinese patent application No. 202322463495.9 discloses the specific structure and working mechanism of the buried parking stall lock. The parking stall lock mainly relies on the rotation of the shaft to drive the flap (i.e. its limiting plate) to operate, so as to realize the switching of the flap between the raised and lowered states. When in the raised state, the local structure of the flap will protrude above the ground, thereby playing the role of blocking the vehicle from entering; and in the lowered state, the upper side of the flap can be flush with the ground, ensuring that the vehicle can smoothly pass over the flap and drive normally.

[0003] However, from the perspective of mechanical structure, the design has certain limitations. Since the rotation of the flap depends on the horizontal shaft installed underground, and during the working process, part of the structure of the flap is higher than the ground after being raised, which causes the force arm of the highest part of the flap relative to the shaft to be large; according to the principle of lever, under the condition of constant resistance (formed by the weight of the flap itself and the change of the speed of the flap), the longer the force arm, the greater the rotation force required for the shaft. In this way, the shaft must have sufficient rotation force to drive the flap to work smoothly, which not only puts high requirements on the power output performance of the shaft, but also may accelerate the wear of the shaft due to the large load it bears in the long-term use, affecting the service life and stability of the parking stall lock.

[0017] Embodiment 1: the labor-saving buried car lock provided by the utility model embodiment 1, as Figs. 1 to 4As shown, including the shell 1, the rotating shaft 2, the flap 3 and several springs 4;The shell 1 is internally provided with containing groove 11;Rotating shaft 2 is provided in containing groove 11;Rotating shaft 2 can rotate around its axis;Flap 3 is fixedly connected with rotating shaft 2;Flap 3 can realize the switching of the lifting state and the lowering state with the rotation of rotating shaft 2;Rotating shaft 2 is below the flap 3 in the lowering state;Flap 3 has opposite first side edge 31 and second side edge 32;First side edge 31 and second side edge 32 are located on both sides of rotating shaft 2 respectively;Containing groove bottom 11 is provided with a plurality of first connecting holes 111;Second side edge 32 is fixed with extension plate 5;Extension plate 5 is provided with a plurality of second connecting holes 51;First connecting hole 111 is on the side of rotating shaft 2 away from second side edge 32;Extension plate 5 is below the second side edge 32 of the flap 3 in the lowering state;Spring 4 is arranged below rotating shaft 2;Both ends of each spring 4 are connected with first connecting hole 111 and second connecting hole 51 respectively.

[0018] The labor-saving buried parking stall lock provided by the embodiment 1 of the utility model is used for blocking vehicles in the lifting state of the flap 3 and allowing vehicles to pass normally in the lowering state of the flap 3; the main power source for driving the rotation of the flap 3 is the rotating shaft 2, and the driving rotation of the rotating shaft 2 and the fixed mode of the rotating shaft 2 and the flap are all prior art, which has been embodied in the comparative document provided in the background art and will not be described here; the difference lies in that the extension plate 5 is fixed on the flap 3 in the structure provided by the embodiment, the second connecting hole 51 is arranged on the extension plate 5, the first connecting hole 111 is arranged on the bottom of the shell 1, and the spring 4 is used to connect the first connecting hole 111 and the second connecting hole 51; when the spring 4 connects the first connecting hole 111 and the second connecting hole 51, it is always in the state of being stretched, that is, no matter in the lifting state or in the lowering state, the spring 4 is always in the state of being stretched; when in the lowering state, the distance between the second connecting hole 52 and the first connecting hole 111 is farther (compared with the lifting state), because the spring is stretched more at this time, the spring has greater elastic potential energy, therefore, the elastic force of the spring tends to switch the flap from the lowering state to the lifting state, and the elastic force of the spring 4 can assist the rotation of the rotating shaft 2 (from the process of rotating the flap 3 from the lowering state to the lifting state); therefore, the rotating force requirement of the rotating shaft 2 of the device provided by the embodiment is low, the force applied by the rotating shaft 2 to the flap 3 is smaller, the abrasion of the rotating shaft 2 is small when in use, thereby prolonging the service life of the buried parking stall lock of the embodiment.

[0019] The labor-saving buried parking stall lock provided by the embodiment 1 of the utility model solves the problem that the rotating force requirement of the rotating shaft of the buried parking stall lock in the prior art is high and easy to be abraded, and can reduce the force required to drive the rotation of the rotating shaft when the flap rotates.

[0020] In the embodiment, the extending direction of the spring 4 is perpendicular to the axis direction of the rotating shaft 2. The spring 4 is arranged perpendicular to the axis direction of the rotating shaft 2, so that the spring 4 can provide elastic force in a more stable manner when the flap 3 rotates around the rotating shaft 2. Since the extending direction of the spring 4 is perpendicular to the rotating plane of the rotating shaft 2, the stress and deformation of the spring 4 are relatively uniform during the lifting and lowering of the flap 3, so that the elastic force provided by the spring 4 is more stable.

[0021] In the embodiment, the extending direction of the first side edge 31, the axis direction of the rotating shaft 2, and the extending direction of the second side edge 32 are parallel to each other, and the distance from the first side edge 31 to the rotating shaft 2 is farther than the distance from the second side edge 32 to the rotating shaft 2. The extending directions of the first side edge 31, the axis of the rotating shaft 2, and the second side edge 32 are parallel to each other, and the distance from the first side edge 31 to the rotating shaft 2 is greater than the distance from the second side edge 32 to the rotating shaft 2. This structure design makes the second side edge 32 lower than the lower side of the rotating shaft 2 when the flap 3 is in the lifted state. By shortening the distance from the second side edge 32 to the rotating shaft 2, the depth of the accommodating groove 11 can be effectively reduced. The reduction of the depth of the accommodating groove 11 reduces the depth of the excavation of the road surface when the ground-mounted parking lock is installed, thereby reducing the installation cost. In the embodiment, the depth of the accommodating groove 11 is reduced by shortening the distance from the second side edge 32 to the rotating shaft 2 (the height of the rotating shaft 2 remains unchanged), but this will cause the rotating shaft 2 to need to overcome greater rotating force to drive the flap 3 to rotate. Because the distance from the second side edge 32 to the rotating shaft 2 is shortened, the structural weight at the second side edge 32 becomes smaller, and the structure at the second side edge 32 originally can provide more gravity to reduce the pressure generated when the first side edge 31 is raised. Therefore, the embodiment increases the spring 4 to offset the loss of gravity, so that the original motor driving the rotating shaft 2 to rotate can still be used normally.

[0022] As a preferred solution, in the embodiment, the spring 4 is in an elongated state that tends to shorten when the flap 3 is in the lowered state, and the length of the spring 4 when the flap 3 is in the lifted state is less than the length of the spring 4 when the flap 3 is in the lowered state. The spring 4 is in a tightened state and tends to shorten, which is the preferred structure of the embodiment, because the structural mass of the flap 3 at the second side edge 32 is smaller than that at the first side edge 31. In other cases, for example, when the weight at the second side edge 32 is greater, the spring 4 can also be arranged in a tightened state and tends to elongate. The spring 3 is a component that provides force to achieve the switching of the flap 3 between the lowered state and the lifted state more easily in the embodiment. Other basic applications of the spring 4 that can achieve easier rotation of the flap 3 are not described in detail in the embodiment.

[0023] The utility model provides a labor saving ground -buried type parking stall lock relates to parking stall lock technical field, including casing, pivot, flap and a plurality of springs, the inside of casing is equipped with containing groove, the pivot sets up in the containing groove, the pivot can rotate around the own axis, the flap with pivot fixed connection, the flap can realize the switching of the state of rising and the state of putting down with the rotation of pivot, the flap below pivot is in the state of putting down, the flap has opposite first side and second side, first side with second side are located the both sides of pivot respectively, a plurality of first connecting hole is seted up in the bottom of containing groove, the fixed extension plate has at second side, a plurality of second connecting hole is seted up in the extension plate, first connecting hole is in the side of pivot is away from second side direction, the second side below extension plate is in the state of putting down the second side of flap, the spring sets up below pivot, the both ends of each spring are connected with first connecting hole and second connecting hole respectively, the labor saving ground -buried type parking stall lock provided by the utility model solves the problem of high rotation force demand and easy wear of the pivot of ground -buried type parking stall lock in the prior art, and can reduce the force required to drive the pivot to rotate when the flap rotates.
