[0003] The perforated spray guardrail with patent number CN202611195U is provided with an upper crossbeam, a lower crossbeam and a column. The ends of the upper crossbeam and the lower crossbeam are fixedly connected to the column. A vertical pipe is provided between the upper crossbeam and the lower crossbeam. A base is provided at the bottom of the column. The upper crossbeam, the lower crossbeam and the vertical pipe are hollow structures. Holes are provided on the upper crossbeam and the lower crossbeam to insert the vertical pipe and correspond to the vertical pipe. The upper side of the cross section of the vertical pipe is an obtuse angle side convex upward, and the bottom side is an obtuse angle side convex downward. The upper side, the bottom side and the upper straight side and the two side sides are connected by smooth transition angles.

[0004] However, research has shown that existing guardrails still have the following defects:

[0005] At present, bolts are generally used to fix the cross bars to the support columns. When connecting the cross bars, tools such as screwdrivers are needed, which is rather troublesome, and the operation of multiple bolts is time-consuming. At the same time, since the vertical bars are clamped by two cross bars, when a vertical bar is damaged and needs to be replaced, the cross bar needs to be removed first before the vertical bar can be taken out from between the two cross bars, which is rather troublesome. Therefore, it is necessary to optimize a composite guardrail that is easy to install and replace through technological innovation and design optimization. Utility Model Content

[0006] At present, bolts are generally used to fix the cross bars to the support columns. When connecting the cross bars, tools such as screwdrivers are required, which is more troublesome, and the operation of multiple bolts is more time-consuming. At the same time, since the vertical bars are clamped by two cross bars, when one vertical bar is damaged and needs to be replaced, the cross bar needs to be removed first before the vertical bar can be taken out from between the two cross bars, which is more troublesome. In order to solve the above problems, the embodiment of the present application provides a composite guardrail that is easy to install and replace. By pulling the rectangular blocks at both ends of the cross bar, the rectangular blocks drive the sliding plate to squeeze the spring 1, and at the same time the insert block enters the sliding cavity, the cross bar is aligned with the slot on the support column, the rectangular block is released, and the spring 1 drives the insert block to be inserted into the slot, thereby completing the rapid installation of the cross bar, improving the installation efficiency.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the present invention to clearly and completely describe the technical solution of the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The instrument placement rack involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] This embodiment introduces a specific structure of a composite guardrail that is easy to install and replace. Figure 1-Figure 7 As shown, a composite guardrail that is easy to install and replace includes:

[0030] Two support columns 2, two cross bars 3 are provided between the two support columns 2, slots 18 are provided at the contact position between the support columns 2 and the cross bars 3, and plug blocks 11 are provided on the side of the cross bars 3 facing the support columns 2. Sliding cavities 13 are provided at both ends of the cross bars 3, and a moving mechanism that can drive the plug blocks 11 to move is provided inside the sliding cavity 13. Several vertical bars 4 are provided between the two cross bars 3, and a cavity 7 is provided inside the cross bar 3. An elastic mechanism that can apply elastic force to the vertical bars 4 is provided inside the cavity 7.

[0031] At present, bolts are generally used to fix the cross bar 3 and the support column 2. When connecting the cross bar 3, tools such as screwdrivers are needed, which is more troublesome, and operating multiple bolts is more time-consuming. The moving mechanism includes a sliding plate 12 provided inside the sliding cavity 13. The sliding plate 12 can slide in the sliding cavity 13. A spring 10 is provided inside the sliding cavity 13. The insert block 11 passes through the cross bar 3 and is fixedly connected to the sliding plate 12. When the spring 10 is in a compressed state, it will drive the sliding plate 12 and the insert block 11 to move in the sliding cavity 13. The insert block 11 will pass through the cross bar 3 and be inserted into the slot 18 on the support column 2, thereby completing the quick installation of the cross bar 3.

[0032] At the same time, a guide column 9 is provided inside the sliding cavity 13, and the guide column 9 passes through the sliding plate 12. The sliding plate 12 can slide on the guide column 9, and the spring 10 is sleeved on the outside of the guide column 9 to facilitate guiding the sliding plate 12 and the spring 10.

[0033] In addition, circular holes 14 are formed on the facing surfaces of the two horizontal bars 3 , which are connected to the cavity 7 . The two ends of the vertical bar 4 are respectively located in the two circular holes 14 , making it easy to insert the vertical bar 4 into the horizontal bar 3 .

[0034] Since the vertical rod 4 is clamped by two cross rods 3, when one vertical rod 4 is damaged and needs to be replaced, it is necessary to remove the cross rod 3 first before the vertical rod 4 can be taken out from between the two cross rods 3, which is more troublesome. The elastic mechanism includes a second guide column 15 fixed inside the cavity 7, and the two ends of the second guide column 15 are fixedly connected to the inner wall of the cavity 7. The second guide column 15 is penetrated by a movable plate 8, and the outer sleeve of the second guide column 15 is provided with a second spring 16. The vertical rod 4 is first inserted into the round hole 14 in the upper cross rod 3, and the vertical rod 4 is pushed hard so that the vertical rod 4 squeezes the movable plate 8. The movable plate 8 will squeeze the spring 2 16. When it cannot be squeezed, the bottom of the vertical rod 4 can be inserted into the round hole 14 in the horizontal rod 3 below. Release your hand. Under the squeezing of the upper spring 2 16, the vertical rod 4 will squeeze the bottom spring 2 16. The two springs 2 16 squeeze each other, so that both ends of the horizontal rod 3 are located inside the cavity 7, which is convenient for quick installation of the vertical rod 4. At the same time, when one of the vertical rods 4 is broken, the broken horizontal rod 3 can be directly replaced by following the above-mentioned reverse operation. It is more convenient and the vertical rod 4 can be quickly replaced without removing the horizontal rod 3 first.

[0035] It is worth noting that a slot 17 is provided on the side of the movable plate 8 facing the vertical rod 4 , and the vertical rod 4 can be inserted into the slot 17 , which facilitates limiting the vertical rod 4 , improves the stability of the vertical rod 4 , and prevents the vertical rod 4 from sliding on the movable plate 8 .

[0036] What's more, rectangular openings 5 are provided at both ends of the crossbar 3, which are connected to the sliding cavity 13. A rectangular block 6 is provided in the rectangular opening 5, which is fixedly connected to the movable plate 8. The rectangular block 6 can drive the sliding plate 12 to slide inside the sliding cavity 13, making it convenient for the sliding plate 12 to drive the plug block 11 to be inserted into the slot 18 and to move the plug block 11 out of the slot 18.

[0037] A base plate 1 is fixed to the bottom of each of the two support columns 2 , and the base plate 1 can be fixed to the ground by bolts, so as to facilitate the installation of the support columns 2 .

[0038] When installation is required, the staff first fixes the support column 2 on the ground through the bottom plate 1, pulls the rectangular blocks 6 at both ends of the crossbar 3, and the rectangular blocks 6 drive the sliding sliding plate 12 to squeeze the spring 10. At the same time, the insert block 11 enters the sliding cavity 13, aligns the crossbar 3 with the slot 18 on the support column 2, loosens the rectangular block 6, and the spring 10 drives the insert block 11 to insert into the slot 18, thereby completing the rapid installation of the crossbar 3 and improving the installation efficiency. Subsequently, the vertical rod 4 is first inserted into the round hole 14 in the upper crossbar 3, and the vertical rod 4 is pushed hard to squeeze and move the vertical rod 4. Plate 8, moving plate 8 will squeeze spring 2 16. When it can no longer be squeezed, the bottom of the vertical rod 4 can be inserted into the round hole 14 in the horizontal rod 3 below. Release your hand. Under the squeezing of the upper spring 2 16, the vertical rod 4 will squeeze the bottom spring 2 16. The two springs 2 16 squeeze each other, so that both ends of the horizontal rod 3 are located inside the cavity 7, which is convenient for quick installation of the vertical rod 4. At the same time, when one of the vertical rods 4 is broken, the broken horizontal rod 3 can be replaced directly by following the above-mentioned reverse operation. It is relatively simple and convenient, and the vertical rod 4 can be quickly replaced without removing the horizontal rod 3 first.

[0039] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
