Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails, and more specifically, particularly relates to a guardrail. Background Art

[0002] As the name suggests, a guardrail is a kind of fence that plays a protective role. When returning farmland to forest, guardrails need to be erected to prevent people from climbing over and damaging the saplings.

[0003] Most existing guardrails are equipped with spikes to prevent people from climbing over them. However, the spikes can easily injure workers when they are carrying them, posing a great safety hazard. After the guardrails are fixed on the soil, the soil becomes loose after the rainy season, which will affect the stability of the guardrails. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a guardrail to solve the problem that most existing guardrails are provided with spikes to prevent people from climbing over, but the spikes can easily injure the workers when they are carrying them, posing a great safety hazard; after the guardrail is fixed on the soil, the soil becomes loose after the rainy season, which will affect the stability of the guardrail.

[0005] The purpose and effect of the protective fence of the utility model are achieved by the following specific technical means:

[0006] A guardrail comprises a guardrail frame; the guardrail frame is a concave structure, the top end surface of the inner wall of the guardrail frame is welded with guardrails in a linear array, and the top of the guardrail is a pointed structure.

[0007] Furthermore, a blocking rod is slidably arranged on the protection rod welded in a linear array, and two locking screws are threadedly connected to the blocking rod, and the two locking screws are threadedly connected to the guardrail frame, and at this time, the upper end of the protection rod is exposed.

[0008] Furthermore, the adjustment portions of the two locking screws are both elliptical structures.

[0009] Furthermore, a fixing assembly is installed on the guardrail frame, and the fixing assembly consists of a fixing block and a ground nail. A fixing block is welded to the front end and the rear end of the guardrail frame, and each fixing block is plugged into a ground nail, and four ground nails are all plugged into the soil.

[0010] Furthermore, the four fixing blocks are all concave block structures.

[0011] Furthermore, two second connection seats are welded to the front end face and the rear end face of the guardrail frame. The second connection seats are composed of two rectangular blocks, and a support arm is rotatably arranged on each second connection seat.

[0012] Furthermore, each of the support arms is provided with a circular hole.

[0013] Furthermore, two first connecting seats are welded on the right end surface of the guardrail frame, and two connecting rods are welded on the left end surface of the guardrail frame. Both connecting rods are L-shaped bent rod structures, and the two connecting rods match the two first connecting seats.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the present application, by setting the baffle rod and the locking screw, on the one hand, during transportation, the two locking screws are loosened, the baffle rod is moved upward until the top of the protective rod is hidden in the baffle rod and the locking screw is tightened, so as to prevent the upper end of the protective rod from injuring the staff during transportation; on the other hand, because the adjustment parts of the two locking screws are both elliptical structures, it is prevented that deliberate saboteurs use a wrench to loosen the locking screws and use the baffle rod to cover the protective rod, which has high safety.

[0016] In the present application, through the setting of the fixing assembly, since the four fixing blocks are all concave block structures, when removing the ground nails, the pry bar can be directly inserted into the groove on the fixing block and pried, which facilitates the removal of the ground nails and is easy to disassemble.

[0017] In the present application, by setting up the second connecting seat and the support arm, when fixing the guardrail frame, the four support arms are rotated and unfolded, and the fixing nails are passed through the circular holes on the support arms and then nailed into the ground. Compared with the existing device, the present device is more stable and avoids the problem of soft soil caused by continuous rainy days, which in turn affects the stability of the guardrail.

[0029] As attached Figure 1 To Attachment Figure 6 As shown:

[0030] The utility model provides a guardrail, comprising a guardrail frame 1; the guardrail frame 1 is a concave structure, the top end surface of the inner wall of the guardrail frame 1 is welded with guard rods 105 in a linear array, and the top of the guard rods 105 is a pointed structure.

[0031] Among them, a blocking rod 106 is slid on the linear array-welded protective rod 105, and two locking screws 107 are threadedly connected to the blocking rod 106. The two locking screws 107 are threadedly connected to the protective railing frame 1. At this time, the upper end of the protective rod 105 is exposed. When transporting, loosen the two locking screws 107, move the blocking rod 106 upward until the top of the protective rod 105 is hidden in the blocking rod 106 and tighten the locking screws 107. During the transportation process, prevent the upper end of the protective rod 105 from injuring the staff. After the installation is completed, loosen the two locking screws 107 and move the blocking rod 106 downward until the upper end of the protective rod 105 is exposed, and threadably connect the two locking screws 107 to the protective railing frame 1.

[0032] The adjustment positions of the two locking screws 107 are both elliptical structures, which prevents vandals from using a wrench to loosen the locking screws 107 and use the blocking rod 106 to cover the protective rod 105 .

[0033] Among them, a fixing component 2 is installed on the guardrail frame 1, and the fixing component 2 is composed of a fixing block 201 and a ground nail 202. A fixing block 201 is welded on the front end and the rear end of the guardrail frame 1, and each fixing block 201 is plugged with a ground nail 202, and four ground nails 202 are all plugged into the soil.

[0034] Among them, the four fixing blocks 201 are all concave block structures. When removing the ground nails 202, the pry bar can be directly inserted into the groove on the fixing block 201 and pried, which facilitates the removal of the ground nails 202.

[0035] Two second connection seats 103 are welded to the front and rear ends of the guardrail frame 1 . The second connection seats 103 are composed of two rectangular blocks. A support arm 104 is rotatably mounted on each of the second connection seats 103 .

[0036] Each support arm 104 is provided with a circular hole. When fixing the guardrail frame 1 through the support arms 104, the four support arms 104 are rotated and unfolded, and the fixing nails are passed through the circular holes on the support arms 104 and then nailed into the ground. Example

[0037] On the basis of embodiment one, two first connecting seats 101 are welded on the right end face of the guardrail frame 1, and two connecting rods 102 are welded on the left end face of the guardrail frame 1. The two connecting rods 102 are both L-shaped bent rod structures. The two connecting rods 102 match the two first connecting seats 101. During use, the connecting rods 102 are inserted into the first connecting seats 101, and multiple guardrail frames 1 can be connected to each other.

[0038] Working principle: When transporting, loosen the two locking screws 107, move the blocking rod 106 upward until the top of the protective rod 105 is hidden in the blocking rod 106 and tighten the locking screws 107. During the transportation process, prevent the upper end of the protective rod 105 from injuring the staff. After the installation is completed, loosen the two locking screws 107 and move the blocking rod 106 downward until the upper end of the protective rod 105 is exposed, and thread the two locking screws 107 on the guardrail frame 1; when fixing, pass the four ground nails 202 through the four fixing blocks 201 and nail them into the soil. When removing the ground nails 202, directly insert the pry bar into the groove on the fixing block 201 and pry it; when performing auxiliary support, rotate and unfold the four support arms 104, and pass the fixing nails through the circular holes on the support arms 104 and then nail them into the ground.
