[0033] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0034] The guardrail of the present utility model is described below with reference to the accompanying drawings.
[0035] The utility model provides a guardrail, such as Figure 1 , Figure 4 and Figure 5 As shown, the guardrail includes:
[0036] A plurality of vertical poles 1 are arranged in parallel and spaced apart from each other vertically;
[0037] A crossbar mechanism 2, comprising a crossbar body 21 connected between two adjacent uprights 1 and a joint assembly 22 detachably mounted on the end of the crossbar body 21, wherein the joint assembly 22 is sleeved on the uprights 1 and can pivot around the uprights 1; and
[0038] The pivot locking member is used for pivot locking of the joint assembly 22 .
[0039] By setting the crossbar body 21 and the joint assembly 22 to be detachably connected, the length of the guardrail can be adjusted by replacing the crossbar body 21 of different lengths, and by changing the length of the guardrail, the protective length of the guardrail can be matched with the actual situation on site, avoiding the phenomenon of gaps or interference due to insufficient or excessive length of the guardrail, and by setting the joint assembly 22 to be sleeved on the vertical pole 1, the angle between adjacent crossbar bodies 21 can be adjusted, so that the guardrail can be connected at any angle at the turning point. Furthermore, the crossbar body 21, the vertical pole 1 and the joint assembly 22 in the utility model can be replaced separately, with strong interchangeability, convenient for mass production and promotion, and easy maintenance.
[0040] like Figure 1 , Figure 2 and Figure 3 As shown, in an embodiment of the utility model, the joint assembly 22 may include a first joint 221, the first joint 221 includes a first sleeve portion 221a for sleeve-fitting with the vertical pole 1 and a first plug-in portion 221b extending from the side of the first sleeve portion 221a, and the first plug-in portion 221b is used to be plug-fitted with the end of the cross bar body 21.
[0041] Specifically, the cross bar body 21 can be a hollow tube, and the size of the first plug-in portion 221b is the same as the inner diameter of the cross bar body 21. One end of the cross bar body 21 can be directly sleeved on one of the vertical poles 1, and the other end can be connected to the adjacent vertical pole 1 by inserting the first joint 221. Of course, the cross bar body 21 can also be connected to the two adjacent vertical poles 1 by inserting the first joints 221 at both ends. The first plug-in portion 221b of the first joint 221 can be extended from the end of the cross bar body 21. By adjusting the insertion depth of the first plug-in portion 221b, the length of the cross bar mechanism 2 can be fine-tuned, and by replacing cross bar bodies 21 of different lengths, the length of the cross bar mechanism 2 can be greatly adjusted. By selecting a cross bar body 21 of a suitable length and adjusting the insertion depth of the first plug-in portion 221b, the vertical poles 1 of any spacing can be accurately matched.
[0042] In an embodiment of the utility model, the first plug-in portion 221b can also be set as a hollow tube, or a plug-in hole can be set on the first plug-in portion 221b, and the cross bar body 21 can be inserted into the first plug-in portion 221b to achieve the plug-in fit between the first plug-in portion 221b and the cross bar body 21.

[0044] like Figure 5 As shown, when the length to be protected is shorter, generally only two vertical poles 1 and a plurality of groups of cross bar mechanisms 2 connected between the two vertical poles 1 are needed to meet the protection requirements. In this state, the connection form of the cross bar body 21 and the two adjacent vertical poles 1 can be: one end of the cross bar body 21 is directly sleeved on one of the vertical poles 1, and the other end is connected to the other vertical pole 1 through the first joint 221 or the second joint 222, or the two ends of the cross bar body 21 are respectively connected to the two vertical poles 1 through the first joint 221 or the second joint 222.
[0045] like Figure 1 , Figure 3 and Figure 4 As shown, when the length to be protected is longer, more vertical poles 1 are needed, and the first joint 221 and the second joint 222 are used in combination, wherein the multiple vertical poles 1 need to include side vertical poles located on both sides of the guardrail and an intermediate vertical pole located between the two side vertical poles. In order to ensure that the adjacent crossbar bodies 21 connected to the intermediate vertical poles are at the same level, a positioning clamping groove 222c can be provided on the second sleeve portion 222a, and the first joint 221 can be positioned by the positioning clamping groove 222c, so that the central axes of the first plug-in portion 221b and the second plug-in portion 222b are in line. At the same time, due to the clamping relationship between the first sleeve portion 221a and the positioning clamping groove 222c, when the height of the crossbar mechanism 2 is positioned, only one set of height limiters 3 is needed to achieve the height positioning of the first joint 221 and the second joint 222 used in combination, which greatly simplifies the installation process.
[0046] like Figure 1 and Figure 5As shown, in the embodiment of the utility model, the crossbar mechanism 2 further includes a sleeve joint 23, which is fixedly mounted on the end of the crossbar body 21 and can be sleeved on the vertical pole 1.

[0047] In the embodiment of the present utility model, there are many ways to rotate and lock the joint assembly 22. Taking the first joint 221 as an example, Figure 1 , Figure 2 and Figure 3 As shown, the first joint 221 may be provided with a socket hole for sleeve-fitting with the vertical pole 1, and the side circumference of the first joint 221 is provided with a locking hole 223 connected to the socket hole, and the vertical pole 1 may be provided with an alignment hole for aligning with the locking hole 223, and the pivot locking member may be one of a locking pin, a screw, and a bolt, and the first joint 221 may be locked and fixed by the pivot locking member passing through the locking hole 223 and the alignment hole. Of course, the pivot locking member may also be a locking sleeve set in the socket hole, etc.
[0048] In the embodiment of the present utility model, locking holes 223 may also be provided on the sleeve joint 23 and the second joint 222 .
[0049] In the embodiment of the utility model, in order to realize the rapid positioning of the installation height of the crossbar mechanism 2, a height limiting structure can be provided on the vertical pole 1. Specifically, Figure 2 As shown, a positioning groove 11 can be provided on the vertical pole 1. The number of the positioning grooves 11 is multiple and they are spaced apart along the height direction of the vertical pole 1. The guardrail can also include a height limiter 3. The height limiter 3 can be an axial retaining spring. The axial retaining spring is clamped in the positioning groove 11 and supports the corresponding first joint 221, second joint 222 or sleeve joint 23 at the bottom, so as to realize the rapid positioning of the installation height of the crossbar mechanism 2. Of course, the height limiting structure can also be an installation positioning hole provided on the vertical pole 1, and the height limiting member 3 can also be a screw, a positioning pin or other component used to be inserted into the installation positioning hole.
