Embodiment 1

[0022] The invisible car bumper that can avoid damage includes the bumper box 1, the bumper box 1 is buried in the ground, the first chute 2 and the second chute 3 are respectively fixed in the bumper box 1, and the first chute 2 is sleeved There is a control rack 4, and a double gear is installed through a bearing in the block box 1. The double gear includes a first gear 5 and a second gear 6. The diameter of the first gear 5 is smaller than the diameter of the second gear 6, and the first gear 5 meshes with the control rack 4, the second gear 6 meshes with a lift rack 7, the other side of the lift rack 7 is sleeved in the second chute 3, and the upper end of the lift rack 7 is fixed with a car block 8; The stop box 1 is provided with a car stop hole for the car stop to protrude, and the side of the car stop box close to the ground is provided with a sealing groove. A torsion spring 12 is also connected between the plate 11 , the sealing plate 11 and the bumper box 1 .

Embodiment 2

[0025] On the basis of the first embodiment, a spring 9 for pushing the control rack 4 upward is connected between the bottom of the control rack 4 and the bottom of the bumper box 1 .

[0026] After the vehicle drives away, the spring 9 can push up the control rack 4, and the elevating rack 7 pulls the car block 8 to move down after the dual gear transmission, and the car block 8 is retracted in the block box 1 again. The return action of spring 9 makes car block 8 can not be caused to block or be damaged to pedestrian, and control tooth bar 4 rises a certain distance on the ground, guarantees that control tooth bar 4 can control car block 8 rise when vehicle enters again, guarantees The repeated use of car block 8 has been realized.

Embodiment 3

[0028] On the basis of Embodiment 1 or Embodiment 2, the upper end of the control rack 4 is covered with a rubber pad 41 . The rubber pad 41 can prevent the control rack 4 from being damaged, and at the same time, the position of the control rack 4 can be smoother to ensure that the vehicle can normally press down the control rack 4 .

Abstract

The invention relates to the field of stop buffers, in particular to a hidden stop buffer possibly avoiding damage. The hidden stop buffer comprises a stop buffer box buried underground, a first sliding groove and a second sliding groove are fixed to the inner portion of the stop buffer box, a control rack is sleeved with the first sliding groove, a duplicate gear is installed in the stop buffer box through a bearing and comprises a first gear and a second gear, the diameter of the first gear is smaller than that of the second gear, the first gear is engaged with the control rack, the second gear is engaged with a lifting rack, the other side of the lifting rack is sleeved with the second sliding groove, and a stop buffer body is fixed to the upper end of the lifting rack; and a stop buffer hole used for allowing the stop buffer body to extending out is formed in the stop buffer box, a sealing groove is formed in the side, close to the ground, of the stop buffer box, a sealing board used for covering the sealing groove is hinged to the stop buffer box, and a torsion spring is further connected between the sealing board and the stop buffer box. The provided automobile stop buffer can be hidden, the stop buffer is automatically lifted when a vehicle is in position, and damage is avoided.

Description

technical field [0001] The invention relates to the field of car bumpers, in particular to an invisible car bumper that can avoid damage. Background technique [0002] The car block is made of stone mortar, and there are also barriers welded by steel rails. Among the lines of freight yards, special lines and section pipelines, many of them are dead-end lines. The safety line, the refuge line, and the arrival and departure lines of individual passenger cars are all dead-end lines. The terminals of the dead line are all equipped with car stops, most of which are made of stone mortar, and some are made of welded steel rails. In addition to the safety line and refuge line, there is an indicator with a red square sign and a red light at the car block. These are collectively referred to as end devices. In order to prevent accidents from colliding with the car block during operation, the use of car stops has been widely promoted in recent years. The car stop is generally set at...
