Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] The utility model discloses a guardrail to solve the prior art problems, can make the column body be in the vertical use state or be in the storage state that sticks with the base, and reduce the occupation space of guardrail in the storage state, and, the clamping structure of limiting pin and clamping part is simple, and the manufacturing cost is lower, and the operation is more convenient, can realize the rapid folding storage of guardrail.

[0031] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0032] As Figures 1-6 The utility model discloses a guardrail to solve the prior art problems, can make the column body be in the vertical use state or be in the storage state that sticks with the base, and reduce the occupation space of guardrail in the storage state, and, the clamping structure of limiting pin and clamping part is simple, and the manufacturing cost is lower, and the operation is more convenient, can realize the rapid folding storage of guardrail.

[0033] In use, the bottom end of the limiting pin 2 is inserted into the first clamping joint, the elastic member is in a compressed state, the annular plate 5 is in abutment with the end of the first clamping joint under the elastic force of the elastic member, and the limiting pin 2 is clamped and fixed with the first clamping joint, so that the fence body is vertically arranged (can be vertical or have a certain angle with the vertical direction) and in a use state. When the protective fence needs to be stored, the limiting pin 2 is pulled upward by the force applying part, the annular plate 5 is separated from the end of the first clamping joint, until the bottom end of the limiting pin 2 is pulled out of the first clamping joint, then the fence body is rotated towards the base until the limiting pin 2 is aligned with the second clamping joint, and then the force applying part is released. Under the elastic force of the elastic member, the bottom end of the limiting pin 2 is inserted into the second clamping joint, the annular plate 5 is in abutment with the end of the second clamping joint, so that the fence body is arranged close to the base, reducing the overall space occupied by the protective fence.

[0034] When the protective fence is stored, the limiting pin 2 is separated from the first clamping joint, the force applying part is released to restore the elastic member to its original length, and when the limiting pin 2 moves to the vicinity of the second clamping joint, the force applying part is pulled again to compress the elastic member, so that the limiting pin 2 is aligned with the second clamping joint, and then the force applying part is released, so that the bottom end of the limiting pin 2 is inserted into the second clamping joint.

[0035] The top end and the bottom end in this embodiment are based on the fence body in the use state.

[0036] Therefore, by clamping the limiting pin 2 with the first clamping joint or the second clamping joint in the clamping part, the fence body can be in a vertical use state or a storage state close to the base, and the space occupied by the protective fence in the storage state is reduced. Moreover, the clamping structure of the limiting pin 2 and the clamping part is simple, the manufacturing cost is lower, the operation is more convenient, and the protective fence can be quickly folded and stored.

[0037] The base in the embodiment comprises a bottom plate 6 and a plurality of walking wheels 7 and support feet 8 arranged at the bottom of the bottom plate 6. The plurality of walking wheels 7 are arranged near one edge of the bottom plate 6, and the plurality of support feet 8 are arranged near the other edge of the bottom plate 6. The two edges are parallel to each other. In use, the walking wheels 7 and the support feet 8 are in contact with the ground, and the height of the walking wheels 7 and the support feet 8 is adapted to ensure that the bottom plate 6 is in or close to a horizontal state. The bottom plate 6 is provided with a plurality of hinge seats 9, and the fence body is hinged to the hinge seats 9. The hinge seats 9 are arranged near one edge of the top of the bottom plate 6, and the edge near the hinge seats 9 corresponds to the edge near the walking wheels 7. In use, the fence body and the bottom plate 6 are approximately in the shape of L, and the fence body can be inclined to the side of the support feet 8 to facilitate its stability, and the friction between the support feet 8 and the ground is large, which can avoid the protective fence from being moved by mistake; in storage, the fence body is close to or even attached to the upper surface of the bottom plate 6. In addition, when the protective fence is in the storage state, the worker can lift the top end of the fence body and make the fence body in an inclined state, at the same time, the support feet 8 are away from the ground, only the walking wheels 7 are in contact with the ground, and the fence body can be moved by the walking wheels 7, achieving the purpose of transferring the protective fence; and after arranging the walking wheels 7 at the bottom of the bottom plate 6, the difficulty of transferring the protective fence can be obviously reduced, thereby reducing the labor intensity of the worker. In addition, when the fence body and the clamping part are in the clamping state, the position of the fence body relative to the bottom plate 6 will not change, ensuring the structural stability of the protective fence during the transfer process.

[0038] The angle adjusting mechanism in the embodiment further comprises a support plate 10, a hinge block 11 and a rotating arm 12. The support plate 10 is fixed on the bottom plate 6, and specifically, it can be connected by bolts, which facilitates the overall disassembly of the angle adjusting mechanism. The hinge block 11 and the clamping part are both fixed on the upper surface of the support plate 10. The bottom end of the rotating arm 12 is hinged to the hinge block 11, and the top end is fixedly connected to the limiting cylinder 1 on one side, and is fixedly connected to the fence body on the other side through a connecting rod.

[0039] The fence body in the embodiment comprises a horizontal rod 13 and a vertical rod 14. The top end of the vertical rod 14 is fixed to the horizontal rod 13, and the bottom end of the vertical rod 14 is hinged to the hinge seat 9 on the upper surface of the base.

[0040] In order to facilitate pulling the limiting pin 2, the top of the limiting pin 2 is connected with a pull rope 15 in the embodiment. The pull rope 15 extends upward and penetrates through the horizontal rod 13, and then connects a pull ring 16, which facilitates the worker to pull the limiting pin 2 through the pull ring 16.

[0041] The clamping part in the embodiment comprises a bent pipe body 17, and the two ends of the bent pipe body 17 are respectively a first clamping head and a second clamping head. The limiting pin 2 can be inserted into the bent pipe body 17, and the diameter of the annular plate 5 is greater than the inner diameter of the bent pipe body 17, which can abut against the end of the bent pipe body 17.
