[0031] like Figures 1 to 5 As shown: a safety guardrail for mining, comprising: a frame plate 1; wherein the front and back sides of the frame plate 1 are both provided with rectangular grooves, a guard plate 2 is slidably and clamped at the rectangular groove of the frame plate 1, a buffer spring 6 is provided between the guard plate 2 and the rectangular groove, one end of the buffer spring 6 is fixedly installed on one side of the guard plate 2, and the end of the buffer spring 6 away from the guard plate 2 is fixedly installed on the inner wall of the rectangular groove, the guard plate 2 can be provided to protect the device, the buffer spring 6 can make the guard plate 2 play an effective buffering role when subjected to external force, decompose the force, and reduce the damage caused by the external force, the number of the guard plates 2 is two, the two guard plates 2 are distributed front and back with the midline of the front side of the frame plate 1 as the axis of symmetry, the number of the buffer springs 6 is eight, and every four buffer springs 6 form a group and are distributed front and back of the frame plate 1, the two guard plates 2 can protect both sides of the device, and the eight buffer springs 6 can make the buffering effect of the front and back of the guard plate 2 stable.

[0032] There are two vertical poles 3, which are arranged on both sides of the frame plate 1. The bottom of the vertical pole 3 is fixedly installed with a support foot 4. The support foot 4 installed on the bottom surface of the vertical pole 3 can stabilize the entire device and can be stably placed. Among them, a card slot is provided on the side of the vertical pole 3 near the upper end, and a slot is provided on the top of the vertical pole 3. The slot is connected to the card slot, and a sliding groove is provided on the inner wall of the slot.

[0033] The disassembly and assembly mechanism 5 is arranged between the frame plate 1 and the upright pole 3. The disassembly and assembly mechanism 5 comprises: an upper clamping column 51, which is arranged between the frame plate 1 and the upright pole 3, and the upper clamping column 51 is clamped in the clamping slot; wherein a groove is formed on the upper surface of the upper clamping column 51; a latch 53, which is inserted in the slot, and the lower end of the latch 53 is located in the clamping slot and is clamped in the groove on the upper clamping column 51.

[0034] In the above-mentioned embodiment, the end of the upper clamping column 51 away from the frame plate 1 is rounded, and the lower end of the pin 53 is rounded. By setting one end of the upper clamping column 51 to a rounded corner and the lower end of the pin 53 to a rounded corner, it is convenient for the upper clamping column 51 to easily push the pin 53 upward after entering the clamping slot, so as to achieve the final clamping effect. A limit block 54 is fixedly installed on the outer wall of the pin 53, and the limit block 54 is slidably set with the slide slot. A spring 55 is fixedly installed on the top surface of the limit block 54, and the end of the spring 55 away from the limit block 54 is fixedly installed with the top of the inner wall of the slide slot. The limit block 54 is set to prevent the pin 53 from falling off, and the spring 55 is set to automatically reset the pin 53.

[0035] The disassembly and assembly mechanism 5 also includes a lower clamping column 56 which is clamped with a groove opened on the side of the vertical rod 3 near the lower end. The end of the lower clamping column 56 away from the vertical rod 3 is fixedly installed on the side of the frame plate 1. The lower clamping column 56 can stabilize the lower end of the frame plate 1 without shaking.

[0036] When installing, just align the upper clamping column 51 with the clamping slot and the lower clamping column 56 with the groove, and then directly clamp them in. The upper clamping column 51 can be squeezed to the lower end of the latch 53 during the process of being inserted into the clamping slot. Since one end of the upper clamping column 51 and one end of the latch 53 are rounded, the latch 53 can be easily squeezed upward. At this time, the upper clamping column 51 continues to be inserted into the clamping slot until the latch 53 is reset to the groove on the surface of the upper clamping column 51 under the action of the spring 55, and finally the effect of quick installation is achieved.

[0037] When disassembling, it is only necessary to move the latch 53 upwards to disengage the lower end of the latch 53 from the groove on the surface of the upper clamping column 51, and finally to pull the upright pole 3 outwards to complete the disassembly.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
