The anti - tipping device includes a support rod, connecting parts arranged on the upper and lower sides of the support rod, a hinge seat arranged at the bottom of the support rod, and a mounting frame rotatably connected to the hinge seat. Usually, more than four groups of anti - tipping devices are symmetrically arranged on the front and back sides of the gate body, and an anti - tipping gate applied by the applicant is disclosed. However, the auxiliary wheels near the middle of the gate take up a large area, and when moving the gate, the first reinforcing rod and the second reinforcing rod need to be disassembled together on the side close to the wall, resulting in inconvenient operation. Therefore, an anti - tipping booster with a smaller volume and without the first and second reinforcing rods is designed. Content of the Utility Model

[0003] Therefore, in view of the above problems, the utility model provides a heavy - duty gate booster, which solves the technical problems that the auxiliary wheels in the middle of the gate take up a large area, and when moving the gate, the first reinforcing rod and the second reinforcing rod need to be disassembled together on the side close to the wall, resulting in inconvenient operation.

[0004] To achieve the above object, the utility model adopts the following technical solutions: A heavy - duty gate booster, including a base, a runner rotatably arranged at the bottom of the base, a guide plate arranged on the top surface of the base, a housing arranged above the base, a frame plate arranged inside the housing, a concave plate arranged between the frame plates and cooperating with the guide plate, a top plate arranged on the top of the frame plate, a cross - plate arranged on the guide plate, and a spring arranged between the top plate and the cross - plate.

[0005] Further, an expansion rod is arranged between the top plate and the base, and the expansion rod passes through the cross - plate.

[0006] Further, the expansion rod includes an outer tube arranged at the bottom of the top plate and an inner tube arranged at the top of the base. The outer tube and the inner tube are slidably connected. An opening for the outer tube to pass through is arranged on the cross - plate, and the outer tube is arranged in the middle of the spring.

[0007] Further, a plurality of stacked reinforcing iron plates are arranged on the side of the concave plate away from the guide plate. Spherical balls are placed inside the reinforcing iron plates. A circular hole for placing the spherical balls is arranged on each of the plurality of reinforcing iron plates. The diameter of the circular hole of the reinforcing iron plate at the middle position gradually becomes smaller to the diameter of the circular hole of the reinforcing iron plates at both sides.

[0008] Further, a triangular iron plate is arranged between the guide plate and the base. A lower hole for the triangular iron plate to pass through is arranged at the bottom of the reinforcing iron plate.

[0009] By adopting the foregoing technical solution, the beneficial effects of the present utility model are as follows:

[0010] For this heavy-duty gate booster, the guide plate is directly connected to the external gate through fasteners, and the connection is more firm. And it moves longitudinally through the guide plates and concave plates on both sides. The spring is placed locally between the guide plate and the concave plate, making the volume structure of this booster smaller, solving the technical problems that the auxiliary wheels in the middle of the gate occupy a large area, and when moving the gate, the first reinforcing rod and the second reinforcing rod need to be disassembled together on the side close to the wall, resulting in inconvenient operation.

[0018] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Refer to Figures 1 to 7 , this embodiment provides a heavy-duty gate booster, including a base 1, a runner 2 rotatably provided at the bottom of the base 1, a guide plate 3 provided on the top surface of the base 1, a housing 4 provided above the base 1, a frame plate 5 provided inside the housing 4, a concave plate 6 provided between the frame plates 5 and cooperating with the guide plate 3, a top plate 7 provided at the top of the frame plate 5, a cross plate 8 provided on the guide plate 3, and a spring 9 provided between the top plate 7 and the cross plate 8.

[0020] When in use, one side of the frame plate is connected to the external gate. After completion, the outer shell is sleeved outside the frame plate and the concave plate. During the use process, under the action of the spring, the cross plate, the guide plate and the base will receive a downward pressure to provide auxiliary support for the concave plate and the connected external gate. The guide plate drives the cross plate and the base to move up and down through the concave plate. The rollers at the bottom of the base will always be in contact with the ground and move along with the terrain to provide auxiliary support for the bottom of the gate. Compared with the original auxiliary wheels, the rollers are closer to the external gate, which will increase the bearing capacity and be less likely to deform under pressure. The guide plate is directly connected to the external gate through fasteners, and the connection is more firm. And it moves longitudinally through the guide plates and the concave plate on both sides. The spring is placed locally between the guide plate and the concave plate, making the volume structure of this booster smaller.

[0021] An expansion link 10 is provided between the top plate 7 and the base 1, and the expansion link 10 passes through the cross plate 8.

[0022] The setting of the expansion link is beneficial to restricting the moving stroke of the base and the guide plate and providing auxiliary guidance, making the guide plate and the concave plate less likely to deform.

[0023] The expansion link 10 includes an outer tube 101 provided at the bottom of the top plate 7 and an inner tube 102 provided at the top of the base 1. The outer tube 101 and the inner tube 102 are slidably connected. An opening 801 for the outer tube 101 to pass through is provided on the cross plate 8, and the outer tube 101 is provided in the middle of the spring 9.

[0024] When the base and the guide plate move up and down, it will drive the inner tube to move inside the outer tube. During the movement of the outer tube and the inner tube, they can pass through the opening on the cross plate, and the spring is provided outside the outer tube, making the internal structure more compact and reducing the volume of the booster.

[0025] A plurality of stacked reinforcing iron plates 11 are provided on the side of the concave plate 6 away from the guide plate 3. A ball 13 is placed inside the reinforcing iron plate 11. A circular hole 111 for placing the ball 13 is provided on a plurality of the reinforcing iron plates 11. The diameter of the circular hole 111 of the reinforcing iron plate 11 at the middle position gradually becomes smaller to the diameter of the circular hole 111 of the reinforcing iron plates 11 at both sides.

[0026] The setting of the reinforcing iron plate can improve the strength of the concave plate, and a plurality of balls can move and rotate inside the reinforcing iron plate, which is beneficial to reducing the longitudinal movement resistance of the guide plate.

[0027] A triangular iron plate 12 is provided between the guide plate 3 and the base 1. A lower hole 112 for the triangular iron plate 12 to pass through is provided at the bottom of the reinforcing iron plate 11.

[0028] The triangular iron plate is beneficial to improving the connection strength between the base and the guide plate.

[0029] An adjusting device 14 is provided between the tops of the concave plates 6. The adjusting device 14 includes a lead screw 141 rotatably provided on the top of the concave plate, sliders 142 provided on both sides of the lead screw 141, and a rotating rod 143 rotatably provided between the slider and the top plate. Spiral grooves 144 are provided on the left and right sides of the lead screw 141, and the thread directions of the spiral grooves on the left and right sides of the lead screw 141 are opposite. A rectangular protrusion 145 for external wrench rotation is provided on one side of the lead screw 141. When it is necessary to adjust the distance between the top plates, an external wrench is inserted into the rectangular protrusion and then rotated. The lead screw will rotate, and the spiral grooves on the outside of the lead screw will rotate to drive the two sliders to move towards the middle position. During the movement of the sliders, the top plate will be driven downward by the rotating rod. Rotating the lead screw in the reverse direction will drive the top plate to move upward, which is beneficial for quickly adjusting the top plate, thereby adjusting the downward pressure of the spring.
