Door leaves 5 are fixedly mounted on one side outer walls of the two sleeves 4. A hydraulic tightening mechanism is arranged on the top outer wall of the base 1. The hinged seat 2 can be limited and fixed by arranging the hydraulic tightening mechanism.
[0034] Among them, the hydraulic tightening mechanism includes a hydraulic cylinder 6, which is fixedly installed on the top outer wall of the base 1. One of the fixed seats 7 is fixedly installed on the output end of the hydraulic cylinder 6, and another fixed seat 7 is fixedly installed on the outer wall of one side of the hinged seat 2. By setting two fixed seats 7, it is convenient to carry out fixed installation. One side outer wall of the two fixed seats 7 is penetrated by a mounting hole 9, and mounting columns 10 are slidably installed in the two mounting holes 9. The mounting holes 9 are set to facilitate the installation of the mounting columns 10. The outer surfaces of both sides of the two mounting columns 10 are provided with threads 11, and nuts 12 are screwed on the two threads 11.
[0035] When in use, insert the two mounting columns 10 into the two corresponding mounting holes 9, and then rotate and install the two nuts 12 on the corresponding mounting columns 10 to complete the fixed connection between the two fixing seats 7 and the hydraulic cylinder 6 and the articulated seat 2, so that the articulated seat 2 can be limited and blocked, and the installation is also relatively convenient.
[0036] Reference Figure 4 and Figure 5 The top outer wall of the base 1 is provided with a rectangular groove 24, in which a box body 18 is slidably mounted, and the box body 18 is fixedly mounted on the bottom outer wall of the hinge seat 2. By providing the rectangular groove 24, the box body 18 can be slidably mounted therein.
[0037] Reference Figure 4 The inner walls of both sides of the box body 18 are rotatably mounted with the same screw 20, which is a bidirectional screw. Two threaded plates 21 are symmetrically screwed on the screw 20, and multiple clamping columns 19 are fixedly mounted on the outer walls of the two threaded plates 21 that are away from each other. A rotating column 22 is fixedly mounted on one end of the screw 20, and one end of the rotating column 22 penetrates through the outer wall of one side of the base 1 and is fixedly mounted with a knob 8. By rotating the knob 8, the knob 8 rotates, thereby driving the rotating column 22 and the screw 20 to rotate, and the screw 20 rotates, thereby driving the two threaded plates 21 to move away from each other and pushing the multiple clamping columns 19 on both sides to move away from each other.
[0038] Reference Figure 4The outer walls on both sides of the box body 18 are provided with a plurality of sliding holes 23, and the plurality of clamping columns 19 are slidably installed in the corresponding sliding holes 23. The sliding holes 23 are provided to assist movement.
