Description

Technical Field

[0001] The utility model relates to a bumper, in particular to a double-safety easy-to-operate anti-collision bumper for heavy trucks. Background Art

[0002] Currently, the anti-collision bumpers suitable for special heavy-duty truck models are difficult to operate, generally requiring at least two people to operate, and have a single safety device and a single self-locking mechanism, making installation and maintenance difficult. Utility Model Content

[0003] The purpose of the utility model is to provide a front protection device for heavy-duty special vehicles. The device has a double safety lock and can be operated by one person at the same time, so as to solve many problems such as inconvenience of single-person operation or double-person operation, small protection area, difficult maintenance, and inconvenient operation.

[0004] The utility model is realized by the following technical solutions:

[0005] A double-insurance, easy-to-operate anti-collision bar for heavy-duty trucks, comprising: an anti-collision guardrail 1, a lock buckle 2, a lock pin fixing bracket 3, a lock pin 4, a pull ring 5, a spring 6, a rotating step 7, a fixed support 8, a retaining spring 9 and a flip shaft 10. The anti-collision guardrail 1 is fixed to the fixed support 8 by means of bolt connection. The anti-collision guardrail 1, the rotating step 7 and the fixed support 8 are connected together by means of a retaining spring 9 and a flip shaft 10. The retaining spring 9 is installed on the inner end face of the fixed support 8 and is clamped on the flip shaft 10. The lock pin fixing bracket 3 is fixed to the vertical beams on both sides of the rotating step 7 by means of welding. The spring 6 is sleeved on the lock pin 4, and the lock pin 4 is installed in the lock pin fixing bracket 3, with the front end extending out to be connected to the pull ring 5. The lock buckle 2 is fixed to the anti-collision guardrail 1, and has a tapered hole that cooperates with the tapered surface at the end of the lock pin 4.

[0006] The utility model adopts double insurance, is easy to operate, has a high safety factor, can effectively reduce the deformation of the cab after a collision, and protect the occupants in the cab. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] Figure 1 This is a diagram of the state of use of the utility model;

[0008] Figure 2 yes Figure 1 A magnified view of part A;

[0009] Figure 3 yes Figure 1 Enlarged view of part B. DETAILED DESCRIPTION

[0010] like Figure 1-3As shown, the utility model is a tiltable front protection device for heavy trucks, which includes: a crash barrier 1, a lock buckle 2, a lock pin fixing bracket 3, a lock pin 4, a pull ring 5, a spring 6, a rotating step 7, a fixed support 8, a retaining spring 9, and a flip shaft 10.

[0011] The installation of the protective device only requires fixing the fixed support 8 with bolts and fixing it to the first crossbeam of the heavy truck.

[0012] The unlocking mechanism is mainly composed of a lock buckle 2, a lock pin 4 and a pull ring 5, which are symmetrically arranged on the vertical beams on both sides of the rotating step 7 to achieve a double safety lock function with a high safety factor. The lock buckle 2 and the lock pin 4 are matched, and the spring 6 is used to realize the force of the lock pin 4 in the Y direction, so that the lock pin 4 is inserted into the tapered hole of the lock buckle 2, thereby realizing the locking function of the rotating step 7. The front end of the lock pin 4 is connected to the pull ring 5, and the lock pin 4 and the pull ring 5 are fixed to the vertical beams on both sides of the rotating step 7 by welding through the lock pin fixing bracket 3. The lock buckle 2 is fixed to the anti-collision guardrail 1 by welding, and the anti-collision guardrail 1 is fixed to the fixed support 8 by bolt connection. The anti-collision guardrail 1, the rotating step 7 and the fixed support 8 are connected together by a retaining spring 9 and a flip shaft 10. The retaining spring 9 is installed on the inner end face of the fixed support 8 and is stuck on the flip shaft 10 to prevent the flip shaft 10 from falling off.

[0013] By pulling the pull rings 5 ​​on both sides at the same time, the lock pin 4 is driven to slide linearly outward to separate the lock pin 4 from the lock buckle 2. At this time, the rotating step 7 is unlocked and separated from the anti-collision guardrail 1. The rotating step 7 is flipped downward with the flip axis 10 as the center to realize the tilting function of the protective device. After tilting, Figure 1 Shown as the dotted line.
