Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated guardrails and relates to a transition quick-connect structure at a connection position of a corrugated guardrail. Background Art

[0002] The corrugated guardrail is a structure installed on both sides of the road for buffering and collision prevention. In order to ensure the integrity and stability between adjacent corrugated guardrails, adjacent corrugated guardrails need to be transitionally connected in sequence. In the prior art, the transition connection between the corrugated guardrails is usually achieved by setting a connecting plate between adjacent corrugated guardrails and inserting connecting bolts in the aligned connecting holes of the connecting plate and the end of the corrugated guardrail. The above-mentioned connection structure requires manual alignment of the holes and then inserting bolts in the holes, which leads to low efficiency of the transition connection of the corrugated guardrail. In addition, as the road bends and changes, the traditional connection structure directly composed of rigid connecting plates and connecting bolts will make it difficult to connect adjacent corrugated guardrails.

[0003] Therefore, in order to solve the above-mentioned technical problems existing in the existing transition connection structure of the corrugated guardrail, the utility model discloses a transition quick-connect structure at the connection position of the corrugated guardrail.

[0027] Example 1:

[0028] A transition quick-connect structure at the connection position of a corrugated guardrail in this embodiment, such as Figure 1-Figure 5 As shown, it is used to connect adjacent corrugated guardrails. The transition quick-connect structure includes a connecting portion arranged between the ends of two adjacent corrugated guardrails. The connecting portion includes a male joint 1 and a female joint 2 hinged to each other. The end of the male joint 1 away from the female joint 2 and the end of the female joint 2 away from the male joint 1 are both provided with a corrugated clamp 3. The corrugated clamp 3 includes corrugated clips 31 arranged on both sides of the end of the corrugated guardrail. Locking fasteners 32 are provided between the upper and lower ends of the corrugated clips 31 on both sides to lock the corrugated clips 31 on both sides toward each other.

[0029] The ends of the male connector 1 and the female connector 2 that are close to the corrugated guardrail are both clamping ends, and the ends of the male connector 1 and the female connector 2 that are away from the corrugated guardrail are both connecting ends. The connecting end of the male connector 1 is hinged to the connecting end of the female connector 2, so that the male connector 1 and the female connector 2 can rotate relative to each other before being locked to adapt to the relative angle generated when the adjacent corrugated guardrails are connected. After the male connector 1 and the female connector 2 are relatively fixed, the corrugated clips 31 at the clamping end of the male connector 1 can be clamped on both sides of the end of the corrugated guardrail in a form-fitting manner, and the corrugated clips 31 on the front and rear sides can be locked by the locking fasteners 32. Similarly, for the female connector 2, the corrugated clips 31 at the clamping end of the female connector 2 can also be clamped on both sides of the end of the corrugated guardrail in a form-fitting manner, and the corrugated clips 31 on the front and rear sides can be locked by the locking fasteners 32, thereby completing a convenient transition connection between the two adjacent corrugated guardrail ends.

[0030] When two adjacent sections of corrugated guardrails need to be separated, it is only necessary to loosen and disassemble the locking fastener 32, and then the corrugated clip 31 can be removed from the end of the corrugated guardrail, thereby finally realizing the convenient disassembly of the two adjacent sections of corrugated guardrails.

[0031] Example 2:

[0032] A transition quick-connect structure at the connection position of the corrugated guardrail is improved on the basis of Example 1, such as Figure 3 and Figure 4 As shown, the locking fastener 32 includes a limiting plate 321 and a locking spring 322. The limiting plate 321 is provided with mounting grooves on both sides, and the locking spring 322 is fixedly installed in the mounting groove. The locking spring 322 elastically contacts the corresponding side of the corrugated guardrail.

[0033] The limiting plate 321 is positioned between the ends of two adjacent sections of the corrugated guardrail. Mounting slots are provided on both sides of the limiting plate 321, corresponding to the ends of the two sections of the corrugated guardrail. The locking spring 322 is provided with a latch that engages with the mounting slot, enabling rapid positioning of the locking spring 322 within the mounting slot. The locking spring 322 is secured within the mounting slot via a connecting bolt, or it can be directly welded to the mounting slot. The locking spring 322 is made of elastic steel sheet. Its inherent elasticity allows it to elastically clamp the sidewalls of the corrugated guardrail, thereby ensuring a secure connection between the corrugated clip 31 and the ends of the adjacent corrugated guardrails.

[0034] Furthermore, a first connecting ear 100 is provided on the top of the limiting plate 321, and a second connecting ear 200 is provided on the top of the locking spring 322. The first connecting ear 100 and the second connecting ear 200 are provided with corresponding connecting holes, and connecting bolts are inserted into these connecting holes. After the locking spring 322 is positioned within the installation slot, the connecting holes on the first connecting ear 100 and the connecting holes on the second connecting ear 200 are aligned, and the connecting bolts can be inserted into the aligned connecting holes to secure the locking spring 322 within the installation slot.

[0035] Furthermore, a vertical plate 323 is provided at the bottom of the stop plate 321. The vertical plate 323 is provided with an auxiliary locking threaded hole. A locking screw is threadedly mounted in the auxiliary locking threaded hole. One end of the locking screw contacts the corresponding side of the corrugated guardrail. The vertical plate 323 extends to the corrugated side surface of the end of the corrugated guardrail. After the corrugated surface of the corrugated guardrail is elastically tightened by the locking spring 322, the locking screw can be screwed into the auxiliary locking threaded hole on the vertical plate 323 to further strengthen the connection between the ends of the corrugated guardrail.

[0036] The rest of this embodiment is the same as that of embodiment 1, so it will not be described again.

[0037] Example 3:

[0038] A transition quick-connect structure at the connection position of a corrugated guardrail is improved on the basis of embodiment 1 or 2, such as Figure 5 As shown, the male joint 1 includes a plurality of male hinges 11 arranged at intervals, and the female joint 2 includes a plurality of female hinges 21 arranged in the interval areas between adjacent male hinges 11, and the male hinges 11 and the female hinges 21 are hingedly connected via hinge shafts.

[0039] The male connector 1 includes at least three spaced male hinges 11, with two gaps formed between the three male hinges 11. The corresponding female connector 2 includes two female hinges 21 with corresponding gaps. The female hinges 21 are inserted into the gaps between the male hinges 11, aligning the hinge holes on the male hinges 11 with the hinge holes on the female hinges 21. The hinge shafts can then be inserted into the aligned hinge holes, achieving a convenient connection between the male connector 1 and the female connector 2.

[0040] Furthermore, both the upper and lower ends of the hinge shaft are provided with externally threaded sections, and the external threads of the externally threaded sections are covered with locking nuts. When the locking nuts are not tightened, the male connector 1 and the female connector 2 can rotate relative to each other. After the relative angle between the male connector 1 and the female connector 2 is adjusted, the locking nuts are tightened to compress the male hinge 11 and the female hinge 21, thereby fixing the relative position between the male connector 1 and the female connector 2.

[0041] Furthermore, a shock-absorbing pad is provided between the mating surfaces of the male hinge 11 and the female hinge 21. By providing the shock-absorbing pad, the impact vibration between the male hinge 11 and the female hinge 21 can be effectively buffered when the corrugated guardrail is hit, thereby avoiding serious deformation of the male hinge 11 and the female hinge 21.

[0042] Furthermore, a plurality of groups of connecting reinforcement ribs are provided between the male hinge 11 and the corrugated clamp 3 and between the female hinge 21 and the corrugated clamp 3. By welding the reinforcement ribs, the connection strength between the male hinge 11 and the female hinge 21 is further strengthened.

[0043] The rest of this embodiment is the same as that of embodiment 1 or 2, and thus will not be described in detail.

[0044] The above are only preferred embodiments of the present invention and do not limit the present invention in any form. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention fall within the scope of protection of the present invention.
