Detailed implementation manners

[0027] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present invention, the following will further describe the solutions of the present invention. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] Combined with Figures 1 to 5 As shown, the safety protection guardrail provided by the embodiment of the present utility model includes a support frame 1, an upper cross bar 2, a lower cross bar 3 and a column 4. The upper cross bar 2 is installed at the upper end of the support frame 1, the lower cross bar 3 is slidably clamped at the lower end of the support frame 1, the column 4 is inserted between the upper cross bar 2 and the lower cross bar 3. A chute 51 is formed in the upper cross bar 2, a rectangular groove 21 is formed at the upper end of the upper cross bar 2, communication grooves 211 are formed on both sides of the lower end of the rectangular groove 21, the communication grooves 211 communicate with the chute 51, an elastic clamping mechanism 5 is installed in the chute 51, and the clamping end of the elastic clamping mechanism 5 is clamped with the end of the column 4 inserted into the upper cross bar 2. An elastic plugging and fixing mechanism 6 is installed in the rectangular groove 21, and the plugging end of the elastic plugging and fixing mechanism 6 passes through the communication groove 211 and is clamped with the elastic clamping mechanism 5. The elastic clamping mechanism 5 and the elastic plugging and fixing mechanism 6 form a column fixing assembly, and the number of the column fixing assemblies is the same as that of the columns 4.

[0030] Wherein, column installation grooves are formed on the inner surfaces of the upper cross bar 2 and the lower cross bar 3, and the column 4 is inserted into the column installation grooves.

[0031] Thus, by arranging a column fixing assembly on each column, when it is necessary to maintain and replace a certain column, only need to lower the lower cross bar and then pull up the plug board, then the column can be pulled out. At the same time, the other columns are still fixed by the column fixing assemblies at their upper ends, which does not affect the work of the staff, realizes the separate detachable fixation of each column, improves the service life of the safety guardrail, and improves the work efficiency of the staff.

[0032] In some embodiments, as Figure 1 、 Figure 4 and Figure 6 shown, the elastic clamping mechanism 5 includes a spring 52, one end of which is fixedly connected to the chute 51, the other end of the spring 52 is fixedly connected with an arc-shaped slider 53, an arc-shaped groove 54 is formed on the column 4, the arc-shaped slider 53 is clamped with the arc-shaped groove 54, and a plug interface 531 is formed on the arc-shaped slider 53, and the plug interface 531 is clamped with the plugging end of the elastic plugging and fixing mechanism 6.

[0033] Thus, the column 4 is inserted into the column installation groove. At this time, due to the elastic force of the spring 52, the arc-shaped slider 53 is pushed into the arc-shaped groove 41 to be clamped with the column 4.

[0034] In some embodiments, as Figure 1 、Figure 4 and Figure 5 As shown in Figure 5 , the elastic plugging and fixing mechanism 6 includes a spring group 62, one end of which is fixedly connected to the bottom surface of the rectangular groove 21. The other end of the spring group 62 is fixedly connected to a straight plate 61. On both sides of the lower end of the straight plate 61, plug plates 63 are fixedly connected. The plug plates 63 pass through the communication groove 211 and are clamped in the plug interface 531.

[0035] Among them, the spring group 62 is composed of springs evenly distributed horizontally along the bottom surface of the rectangular groove 21. A waterproof plate 7 is hinged to the upper end of the rectangular groove 21, and the waterproof plate 7 fits against the inner wall of the rectangular groove 21.

[0036] Thus, by pulling up the straight plate 61, the plug plates 63 are driven to leave the plug interface 531. At this time, the column 4 can be pulled out. After being pulled out, the straight plate 61 is reset due to the pulling force of the spring group 62. When assembly is required, the straight plate 61 is pulled up again, the column 4 is inserted into the column installation groove, and the straight plate 61 is released, driving the plug plates 63 to reset to plug and fix the arc-shaped slider 53.

[0037] In some embodiments, as Figure 1 、 Figure 4 and Figure 5 shown, it further includes a fixing rod 9. Through grooves 11 are opened on the side walls of both sides of the support frame 1, and slots 31 are provided on both sides of the lower cross bar 3. The fixing rod 9 passes through the through grooves 11 and is clamped with the slots 31.

[0038] Among them, a clamping opening is opened on the outside of the through groove 11. Limit blocks 8 are provided on the inner walls of both sides of the support frame 1, which fit against the upper surface of the fixed lower cross bar 3. The two sides of the lower end of the support frame 1 are fixedly connected with bases 10.

[0039] Thus, when the column 4 needs to be maintained and replaced, the fixing rod 9 is pulled out of the through groove 11, and the limit blocks 8 are provided to prevent the lower cross bar 3 from rising excessively and damaging the column 4.

[0040] Next, a specific embodiment of the present utility model will be described in conjunction with the attached Figures 1 - 5 description:

[0041] As Figures 1 to 5As shown, it includes a support frame 1, an upper crossbar 2, a lower crossbar 3 and a column 4. The upper crossbar 2 is installed at the upper end of the support frame 1. The lower crossbar 3 is slidably clamped at the lower end of the support frame 1. The column 4 is inserted between the upper crossbar 2 and the lower crossbar 3. A chute 51 is provided in the upper crossbar 2. A rectangular groove 21 is provided at the upper end of the upper crossbar 2. Communication grooves 211 are provided on both sides at the lower end of the rectangular groove 21. The communication grooves 211 communicate with the chute 51. An elastic clamping mechanism 5 is installed in the chute 51. The clamping end of the elastic clamping mechanism 5 is clamped with the end of the column 4 inserted into the upper crossbar 2. An elastic plugging and fixing mechanism 6 is installed in the rectangular groove 21. The plugging end of the elastic plugging and fixing mechanism 6 passes through the communication groove 211 and is clamped with the elastic clamping mechanism 5. The elastic clamping mechanism 5 and the elastic plugging and fixing mechanism 6 form a column fixing assembly. The number of the column fixing assemblies is the same as that of the columns 4.

[0042] During actual use, when the column 4 needs to be maintained and replaced, the fixing rod 9 is pulled out, the lower crossbar 3 is moved to the lowermost end of the support frame 1, the waterproof plate 7 is opened, the straight plate 61 is pulled up to drive the plug plate 63 to leave the plug interface 531. At this time, the column 4 can be pulled out. After being pulled out, the straight plate 61 is reset due to the pulling force of the spring group 62. When assembly is required, the straight plate 61 is pulled up again, and the column 4 is inserted into the column installation groove. At this time, due to the elastic force of the spring 52, the arc-shaped slider 53 is pushed into the arc-shaped groove 41 to be clamped with the column 4. The straight plate 61 is released, driving the plug plate 63 to reset to plug and fix the arc-shaped slider 53, completing the detachable fixing of each column separately, improving the service life of the safety guardrail and the work efficiency of the staff.
