[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see the appendix Figures 1 to 5 As shown in the embodiment of this utility model, a prefabricated subway station equipment area hoisting hole cover fixing device is applied to cover plate 2. Cover plate 2 is installed on the inner side of the hoisting hole on the mounting surface 1 by a hinge. It includes a rotating seat 3 and a fixed seat 5. The rotating seat 3 and the fixed seat 5 are respectively fixed on the left and right sides of the mounting surface 1 near the cover plate 2. The rotating seat 3 is rotatably connected to a pressure rod 4. The other end of the pressure rod 4 is detachably connected to the fixed seat 5.

[0030] The pressure rod 4 is placed over the gap of the cover plate 2, and a pressure pad 12 is fixedly connected to its lower end. The pressure pad 12 contacts the gap of the cover plate 2. After the pressure rod 4 is installed, the pressure pad 12 will contact the gap at the closed part of the cover plate 2, thereby covering the gap and preventing dust or debris from falling into the equipment space below through the gap of the cover plate 2. At the same time, after the pressure rod 4 is installed, it will exert a downward squeezing force on the cover plate 2 through the pressure pad 12, thereby fixing the cover plate 2, reducing the vibration of the cover plate 2, and thus reducing abnormal noise.

[0031] The pressure pad 12 can be connected and fixed to the pressure rod 4 by bolts, making it easy to replace. The pressure pad 12 can be made of wear-resistant rubber, which has a long service life and is relatively soft, so it can tightly cover the gaps and also play a certain role in cushioning.

[0032] In this embodiment, the fixing base 5 includes a base body 51 fixed to the mounting surface 1. A mating groove 52 is formed on the upper end face of the base body 51. Two connecting studs 53 are fixedly connected inside the mating groove 52. A connecting block 10 is fixed to the end of the pressure rod 4. Two mounting holes are formed on the inner side of the connecting block 10, wherein the inner diameter of the mounting holes is larger than the diameter of the connecting studs 53. The connecting block 10 covers the mating groove 52. The upper end of the connecting stud 53 passes through the mounting hole of the connecting block 10 and is threadedly fitted with a threaded sleeve 11. The threaded sleeve 11 and the connecting block... 10 abuts against the mounting surface 1, and the pressure rod 4 is connected to the mounting surface 1 via the rotating seat 3. After the end of the pressure rod 4 is fixed to the fixing seat 5, a stable connection structure is formed. When fixing, first rotate the pressure rod 4 to cover the connecting block 10 on the mating groove 52. Since the inner diameter of the mounting hole on the connecting block 10 is larger than the diameter of the connecting stud 53, the connecting stud 53 will not interfere with the mating of the connecting block 10 and the mating groove 52. Then install the screw sleeve 11 to complete the fixing of the pressure rod 4. When disassembling, unscrew the screw sleeve 11 to unlock the pressure rod 4.

[0033] The screw sleeve 11 is hexagonal in shape, making it easy to disassemble using common tools such as wrenches.

[0034] Please see Figure 1 and Figures 4 to 5 As shown, in one embodiment of this utility model, two staggered insertion rods 7 are inserted into both sides of the pressure rod 4. At least two clamping components 8 are fixed at intervals on the outer ends of the insertion rods 7. The clamping components 8 abut against the cover plate 2. Two insertion seats 9 are fixed on both the upper and lower sides of the upper end surface of the mounting surface 1. The ends of the insertion rods 7 are inserted into the insertion seats 9. By setting the insertion rods 7 and the clamping components 8, the stability of the cover plate 2 after it is closed can be further improved and vibration can be prevented.

[0035] The clamping assembly 8 includes a fixing frame 81 fixedly connected to the plug rod 7. The outer end of the fixing frame 81 is threadedly connected to an adjusting screw 82. The lower end of the adjusting screw 82 is fixedly connected to a pressure plate 83. The lower end of the pressure plate 83 abuts against the cover plate 2. When in use, the clamping assembly 8 drives the cover plate 2 to press down by rotating the adjusting screw 82, pressing it tightly against the surface of the cover plate 2. Multiple clamping assemblies 8 are provided to form a multi-point pressing and fixing structure, thereby further ensuring the stability of the cover plate 2 and preventing the cover plate 2 from vibrating and making abnormal noise.

[0036] In this embodiment, adjustment components 6 are provided on both sides of the upper end face of the pressure rod 4. The adjustment components 6 are used to adjust the extension degree of the plug rod 7.

[0037] Specifically, the adjusting assembly 6 includes a housing 61 fixed to the pressure rod 4. Inside the housing 61, a worm gear 63 and a worm wheel 64 are rotatably connected. The worm wheel 64 is fixedly connected to a gear 65 rotating inside the pressure rod 4. The end of the plug rod 7 extending into the pressure rod 4 is provided with a toothed groove 14, which meshes with the worm wheel 64. The outer end of the worm gear 63 is fixedly connected to a rotating head 62. When the adjusting assembly 6 is in use, the rotating head 62 is rotated by a tool, which drives the gear 65 to rotate after being transmitted through the worm gear 63 and the worm wheel 64. Since the gear 65 is connected to the plug rod 7 through the toothed groove 14, the rotation of the gear 65 can drive the plug rod 7 to extend and retract, thereby locking and separating the plug rod 7 from the plug seat 9.

[0038] In this embodiment, sleeves 13 are fixedly connected to both sides of the outer end of the pressure rod 4. The sleeves 13 are sleeved on the outer end of the plug rod 7. When the plug rod 7 moves, it will slide along the sleeves 13. The sleeves 13 can improve the stability of the plug rod 7 when it moves and facilitate alignment with the plug seat 9.

[0039] Working principle: In use, first assemble each part in its corresponding position on the outer periphery of the cover plate 2, then close the pressure rod 4 so that the connecting block 10 and the mating groove 52 are installed, and install the screw sleeve 11 so that the pressure pad 12 is tightly pressed into the gap of the cover plate 2. Then, adjust the assembly 6 to make the insertion rod 7 and the insertion seat 9 stably connected, and tighten the clamping assembly 8 to complete the fixation of the cover plate 2. When it is necessary to open the cover plate 2, first separate the insertion rod 7 and the insertion seat 9 by adjusting the assembly 6, then remove the screw sleeve 11 to unlock the pressure rod 4, and then flip the pressure rod 4 up to release the fixation of the cover plate 2.

[0040] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
