Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated guardrails, and relates to a corrugated guardrail for back-mounted installation. Background Technique

[0002] The corrugated guardrail is an anti-collision structure commonly used on both sides of roads. When a vehicle hits the corrugated guardrail, the impact force can be dispersed and buffered by the wavy stress surface of the corrugated guardrail. In the prior art, the corrugated guardrail is fixed outside the column structure by relying on a connecting seat, and the corrugated guardrail and the connecting seat are usually connected by connecting bolts. This results in the need to set connecting holes at corresponding positions on the corrugated guardrail and the connecting seat for the connecting bolts to be inserted. And during the process of installing the corrugated guardrail on the connecting seat, it is necessary to align numerous holes on the corrugated guardrail with numerous holes on the connecting seat one by one, and then the connecting bolts can be smoothly inserted and installed to achieve the connection between the corrugated guardrail and the connecting seat. Once the holes are misaligned, it is difficult or even impossible to insert and install the connecting bolts. This leads to very low efficiency in connecting the corrugated guardrail and the connecting seat by the existing connecting bolts, and it requires workers to manually align the holes, with the operation being very inefficient and inconvenient. Moreover, after the existing corrugated guardrail is penetrated with connecting bolts, the ends of the bolts will be exposed on the side of the corrugated guardrail close to the road, affecting the aesthetics of the corrugated guardrail and also reducing the overall anti-impact performance of the stress surface of the corrugated guardrail.

[0003] Therefore, in view of the above defects existing in the installation structure between the existing corrugated guardrail and the connecting seat, the utility model discloses a corrugated guardrail for back-mounted installation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a corrugated guardrail for back-mounted installation, which replaces the structure of the traditional corrugated guardrail connected to the installation column by numerous connecting bolts, and can achieve quick and efficient hanging connection between the corrugated guardrail and the installation column, improving the installation efficiency of the corrugated guardrail.

[0005] The utility model is realized by the following technical solutions:

[0006] A corrugated guardrail for back-mounted installation includes an installation column, a connecting seat is fixedly installed outside the installation column, a corrugated guardrail is arranged on one side of the connecting seat, a hanging part is arranged on the side of the connecting seat close to the corrugated guardrail, and a docking part corresponding to the hanging part for clamping is arranged on the side of the connecting seat close to the corrugated guardrail; a docking cavity is arranged inside the hanging part, at least one buckle is arranged at the opening of the docking cavity; one end of the docking part extends into the docking cavity, and at least one hanging opening is arranged on the outer side surface of the docking part, and a locking part is sleeved outside the hanging part, and the locking part rotates and squeezes the buckle into the hanging opening to achieve clamping.

[0007] Join one end of the docking part with the docking cavity, then rotate the locking part so that the locking part squeezes the buckle towards the direction close to the hanging opening until the buckle enters the inside of the hanging opening and is clamped with the hanging opening, thereby realizing the docking between the docking part and the hanging part. At this time, the corrugated guardrail is hung on one side of the connecting seat in a back-hanging manner. The connecting seat is pre-connected to the through hole on the installation column through connecting bolts, thereby realizing the convenient hanging of the corrugated guardrail outside the installation column. When the corrugated guardrail needs to be maintained or replaced, only need to rotate the locking part in the reverse direction so that the locking part no longer squeezes the buckle. At this time, the buckle disengages from the hanging opening, and the quick separation of the docking part and the hanging part can be realized, and finally the convenient and efficient disassembly of the corrugated guardrail can be realized.

[0008] To better implement the present utility model, further, the hanging part includes a hanging cylinder body, a docking cavity is arranged at the center of the hanging cylinder body, and four groups of buckles are evenly arranged along the circumferential direction at the edge of the opening of the docking cavity; a locking part is sleeved outside the hanging cylinder body in a threaded fit, and the locking part squeezes the buckle to contract towards the axis direction of the docking cavity by its own rotation.

[0009] To better implement the present utility model, further, a compression inclined surface is arranged on the outer side of the buckle, and an extrusion inclined surface matched with the compression inclined surface is arranged on the inner side of the locking part.

[0010] To better implement the present utility model, further, the locking part includes a locking nut, the locking nut is sleeved outside the hanging cylinder body in a threaded manner, and an extrusion inclined surface is arranged on the inner side of the locking nut.

[0011] To better implement the present utility model, further, an arc-shaped hole is arranged on the cylinder wall of the hanging cylinder body, a locking hole is arranged on the locking nut, and an anti-loosening pin is inserted into the locking hole and the arc-shaped hole.

[0012] To better implement the present utility model, further, the docking part includes a docking block, the docking block is inserted into the docking cavity in a matching manner; a plurality of hanging openings are arranged along the circumferential direction on the outer side surface of the docking block.

[0013] To better implement the present utility model, further, the docking block is in the shape of a frustum of a cone.

[0014] To better implement the present utility model, further, a connecting plate is arranged on the side of the docking block close to the corrugated guardrail, and the connecting plate is fixedly connected to the trough side of the corrugated guardrail.

[0015] Compared with the prior art, the present utility model has the following advantages and beneficial effects:

[0016] The utility model realizes the convenient and efficient installation of the corrugated guardrail on the connecting seat by arranging a hanging part on one side of the connecting seat and a docking part on one side of the corrugated guardrail, and then through the quick positioning and clamping between the hanging part and the docking part, so that the staff no longer needs to drill a large number of holes during the installation of the corrugated guardrail, greatly improving the installation efficiency of the corrugated guardrail; at the same time, through the back-hanging structure between the hanging part and the docking part, the connecting end of the corrugated guardrail is completely hidden on the back side of the stress surface, and there is no need to arrange a large number of holes on the stress surface of the corrugated guardrail, which not only ensures the aesthetics of the corrugated guardrail, but also does not affect the overall impact resistance of the stress surface due to drilling holes.

[0028] Embodiment 1:

[0029] A corrugated guardrail for back mounting in this embodiment, as Figures 1 - 5 shown, includes an installation column 1. A connection seat 2 is fixedly installed on the outside of the installation column 1. A corrugated guardrail 3 is arranged on one side of the connection seat 2. A hanging part 4 is arranged on the side of the connection seat 2 close to the corrugated guardrail 3. A docking part 5 corresponding to the hanging part 4 is arranged on the side of the connection seat 2 close to the corrugated guardrail 3. A docking cavity 41 is arranged inside the hanging part 4, and at least one buckle 42 is arranged at the opening of the docking cavity 41. One end of the docking part 5 extends into the docking cavity 41, and at least one hanging opening 51 is arranged on the outer side surface of the docking part 5. A locking part 6 is sleeved outside the hanging part 4, and the locking part 6 rotates and presses the buckle 42 into the hanging opening 51 to achieve clamping.

[0030] The connecting seat 2 is fixed to the outer side of the mounting column 1 through connecting bolts, and the intercepting seat 2 is used to support and fix the corrugated guardrail 3. The docking member 5 on one side of the corrugated guardrail 3 is correspondingly inserted into the interior of the docking cavity 41, and the corrugated guardrail 3 is pushed towards the direction close to the mounting column 1, so that the buckle 42 at the opening of the docking cavity 41 enters the hanging opening 51 on the outer side surface of the docking member 5, realizing the pre-splicing of the hanging member 4 and the docking member 5. Then rotate the locking member 6, so that the locking member 6 presses the buckle 42 into the hanging opening 51, ensuring the stable clamping of the buckle 42 and the hanging opening 51, and further realizing the convenient clamping of the corrugated guardrail 3 on the connecting seat 2. When it is necessary to disassemble the corrugated guardrail 3, only need to rotate the locking member 6 reversely, so that the locking member 6 no longer presses the buckle 42. At this time, under the action of an external force, pull the corrugated guardrail 3, so that the buckle 42 disengages from the hanging opening 51, and the convenient separation between the corrugated guardrail 3 and the connecting seat 2 can be realized.

[0031] Through the convenient clamping structure between the hanging member 4 and the docking member 5, the quick back-hanging installation of the corrugated guardrail 3 on one side of the connecting seat 2 is realized, replacing the structure of connecting the corrugated guardrail 3 and the connecting seat 2 with connecting bolts and connecting pins in the prior art, and greatly improving the installation efficiency of the corrugated guardrail 3. The locking pressure of the locking member 6 ensures that the buckle 42 can be stably clamped inside the hanging opening 51, thereby preventing the corrugated guardrail 3 from falling off the connecting seat 2.

[0032] Embodiment 2:

[0033] A back-hanging corrugated guardrail, improved on the basis of Embodiment 1, as Figure 4 shown, the hanging member 4 includes a hanging cylinder body 43, a docking cavity 41 is provided at the center of the hanging cylinder body 43, and four groups of buckles 42 are uniformly arranged along the circumferential direction at the edge of the opening of the docking cavity 41; an external thread of the hanging cylinder body 43 is in threaded fit with a locking member 6 sleeved thereon, and the locking member 6 contracts towards the axis direction of the docking cavity 41 by rotating itself to press the buckle 42.

[0034] An external thread is provided on the outer cylinder wall of the hanging cylinder body 42, and an internal thread is provided in the inner hole of the locking member 6, thereby realizing the threaded fit installation of the locking member 6 outside the hanging cylinder body 42. At the same time, a pressure-receiving part is provided on the outer side surface of the buckle 42, and an extrusion part cooperating with the pressure-receiving part is provided on the inner hole of the locking member 6. By rotating the locking member 6, the extrusion part presses the buckle 42 towards the direction close to the hanging opening 51, ensuring that the buckle 42 can be stably clamped inside the hanging opening 51.

[0035] Further, as Figure 3 shown, a pressure-receiving inclined surface 421 is provided on the outer side of the buckle 42; as Figure 6 shown, an extrusion inclined surface 422 cooperating with the pressure-receiving inclined surface 421 is provided on the inner side of the locking member 6.

[0036] When the locking member 6 rotates forward, the pressing inclined surface 422 presses the pressed inclined surface 421 towards the direction close to the hanging opening 51, and then presses the buckle 42 into the hanging opening 51, and ensures that the buckle 42 can be firmly installed inside the hanging opening 51. When the locking member 6 rotates reversely, at this time, the pressing inclined surface 422 moves away from the pressed inclined surface 421, so that the pressing inclined surface 422 no longer presses the pressed inclined surface 421. At this time, under the action of an external force pulling the corrugated guardrail 3, the buckle 42 is disengaged from the inside of the hanging opening 51.

[0037] Other parts of this embodiment are the same as those of Embodiment 1, so they will not be described in detail.

[0038] Embodiment 3:

[0039] A corrugated guardrail for back mounting, improved on the basis of Embodiment 1 or 2, as Figure 3 shown, the locking member 6 includes a locking nut 61, the locking nut 61 is threadedly sleeved outside the hanging cylinder 43, and a pressing inclined surface 422 is arranged inside the locking nut 61. The threaded hole of the locking nut 61 is in threaded fit connection with the external thread on the outer wall of the hanging cylinder 43, and a pressing inclined surface 422 is arranged at one end of the inner hole of the locking nut 61 close to the pressed inclined surface 421. By rotating the locking nut 61, the pressing inclined surface 422 presses the pressed inclined surface 421, and at the same time, after stopping rotating the locking nut 61, through the self-locking thread fit connection structure between the threaded hole of the locking nut 61 and the external thread on the outer wall of the hanging cylinder 43, it is avoided that the buckle 42 directly disengages from the hanging opening 51.

[0040] Further, as Figure 4 shown, an arc-shaped hole is arranged on the barrel wall of the hanging cylinder 43, a locking hole 611 is arranged on the locking nut 61, and an anti-loosening pin 62 is inserted in the locking hole 611 and the arc-shaped hole. When the locking nut 61 rotates and locks in place, at this time, the locking hole 611 is aligned with the arc-shaped hole, and the anti-loosening pin 62 can be inserted in the locking hole 611 and the arc-shaped hole. Through the cooperation between the anti-loosening pin 62 and the arc-shaped hole, the rotation position of the locking nut 61 is restricted to avoid loosening of the locking nut 61.

[0041] Other parts of this embodiment are the same as those of Embodiment 1 or 2, so they will not be described in detail.

[0042] Embodiment 4:

[0043] A corrugated guardrail for back mounting, improved on the basis of any one of Embodiments 1-3, as Figure 5As shown in the figure, the docking part 5 includes a docking block 52, and the docking block 52 is in plug-in fit with the docking cavity 41; a plurality of hanging openings 51 are arranged circumferentially on the outer side surface of the docking block 52. The docking block 52 and the docking cavity 41 are in plug-in fit and guiding, so that the corrugated guardrail 3 can be quickly pre-positioned and installed on one side of the connecting seat 2, without the need to align the connecting holes on the corrugated guardrail 3 with the connecting holes on the connecting seat 2 as in the prior art, greatly improving the installation and positioning efficiency of the corrugated guardrail 3.

[0044] Further, the docking block 52 is in the shape of a frustum of a cone. Correspondingly, the inner cavity shape of the docking cavity 41 is a tapered hole. The quick guiding and positioning installation of the corrugated guardrail 3 on one side of the connecting seat 2 is realized through the cooperation of the docking block 52 and the docking cavity 41.

[0045] Further, a connecting plate is arranged on the side of the docking block 52 close to the corrugated guardrail 3, and the connecting plate is fixedly connected to the valley side of the corrugated guardrail 3. The end face of the docking block 52 on the side close to the corrugated guardrail 3 is directly welded to the corrugated guardrail 3 or connected by connecting bolts.

[0046] Other parts of this embodiment are the same as any one of Embodiments 1-3, so they will not be described in detail.

[0047] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention.
