The limit block does not contact the connecting tube 65, which can avoid the connection tube 65 and the threaded rod 67 from being separated in actual use, thereby improving the stability of the overall device.
[0027] The second adjustment component 7 is used to adjust the connection state between the second guardrail 4 and the pillar 2. The second adjustment component 7 is arranged on the contact surface between the second guardrail 4 and the pillar 2. The second adjustment component 7 includes a movable ring 71, an insert cylinder 72, a rotating shaft 73, a fixed rod 74, an insert block 75, a second spring 76 and a connecting rod 77. The movable ring 71 is fixedly installed on the end of the fixed rod 74, the insert cylinder 72 is fixedly installed on the side of the second guardrail 4 close to the pillar 2, the rotating shaft 73 is rotatably arranged on the insert cylinder 72, the fixed rod 74 is fixedly installed on the rotating shaft 73, the insert block 75 is slidably arranged on the insert cylinder 72 and plugged into the pillar 2, the two ends of the second spring 76 are fixedly connected to the insert block 75 and the insert cylinder 72 respectively, the two ends of the connecting rod 77 are movably connected to the insert block 75 and the rotating shaft 73 respectively, and a socket is provided on the pillar 2, and the shape of the socket is consistent with the cross-sectional shape of the insert cylinder 72, see Figure 7 The side view of the socket is composed of an arc and a straight line, which can limit the direction in which the insert tube 72 is inserted into the pillar 2, ensuring that the insert block 75 can reach the predetermined position and be inserted into the interior of the pillar 2, thereby ensuring the rationality of the overall device and achieving the pre-established purpose.
[0028] Working principle: in actual use, the guard plate 1 is set up on the pillar 2 as the top guard plate, and the second guardrail 4 is slidably set up on the first guardrail 3 to form a guardrail part. The second guardrail 4 is then connected to the pillar 2 using the second adjustment component 7 to form a safety protection frame for providing protection function. Finally, the entire structure is installed on the workbench 5 through the mounting plate at the bottom of the pillar 2 for protection.
[0029] When the size of the entire safety protection frame needs to be adjusted for workbenches 5 of different sizes, the movable ring 71 is rotated, and the rotating shaft 73 fixedly connected to the movable ring 71 through the fixing rod 74 rotates with it. Under the action of the connecting rod 77 movably connected to the plug block 75 and the rotating shaft 73 at both ends, the plug block 75 sliding inside the insert cylinder 72 will slide toward the inside of the insert cylinder 72 as the movable ring 71 rotates, so that the plug block 75 does not contact the pillar 2. At this time, the second guardrail 4 can be removed from the pillar 2 to remove the guardrail part of the safety protection frame. At this time, the U-shaped seat 62 is rotated again. The threaded rod 67 is movable on the upper side, and the connecting tube 65 threadedly connected on the threaded rod 67 is also slidably connected with the fixed tube 63 fixed on the U-shaped seat 62. Therefore, as the threaded rod 67 rotates, the connecting tube 65 will slide up and down, and the conical block 61 fixed at the lower end of the connecting tube 65 will slide synchronously with it. The conical block 61 also contacts the ball head rod 64 sliding inside the guard plate 1. The ball head rod 64 is fixedly connected to the pillar 2. At the same time, the ball head rod 64 also uses a first spring 66 to further connect with the guard plate 1. Because the contact surface between the conical block 61 and the ball head rod 64 is an inclined surface, refer to Figure 3 After the conical block 61 slides downward, it will squeeze the ball head rod 64 outward, causing the support 2 to slide outward on the guard plate 1. Figure 2 After the conical block 61 slides, the distance between the multiple pillars 2 will be adjusted until the workbench 5 of the corresponding size is reached, and the threaded rod 67 can be stopped. At this time, the second guardrail 4 is slid again, so that the insert 72 fixed on the second guardrail 4 is inserted into the interior of the pillar 2, and then the restriction of the movable ring 71 is released. Under the action of the second spring 76 at both ends respectively connected to the insert 72 and the insert block 75, the insert block 75 will be pushed toward the outside of the insert 72 and inserted into the interior of the pillar 2, thereby locking the second guardrail 4 on the pillar 2, and completing the adjustment of the size of the entire safety protection frame.
