An extrusion rod 205 is slidably arranged on the combination slot 203. A vertical plate 204 is movably arranged on the side wall of the extrusion rod 205. The vertical plate 204 is horizontally slidably connected to the positioning cover 201. A shovel plate 2041 is installed at the bottom of the vertical plate 204. A pressing plate 2045 is installed on the extrusion rod 205. The pressing plate 2045 movably penetrates the vertical plate 204. The pressing plate 2045 and the shovel plate 2041 are connected to the positioning convex opening on the side wall of the garage wall 101. 1011 corresponds to block 1011; when the positioning cover 201 needs to be installed, the operator first rotates the turntable 202, and the position of the combination groove 203 on the turntable 202 changes. First, the extrusion rod 205 slides along the expansion groove 2031, thereby driving the extrusion rod 205 and the vertical plate 204 to move to both sides. The shovel plate 2041 at the bottom of the vertical plate 204 can now slide to the top of the positioning protrusion 1011. When the extrusion rod 205 slides along the combination groove 203 to the pull-down groove 2032, the extrusion rod 205 is driven to slide downward through the lifting block 2033. The downward sliding of the extrusion rod 205 can also drive the pressing plate 2045 to move toward the positioning protrusion 1011. Through the mutual cooperation of the shovel plate 2041 and the pressing plate 2045, the positioning cover 201 can finally be connected to the garage wall 101, and the operation is more convenient, which is convenient for improving installation efficiency.

At this time, the cross plate 301 rotates, and the angle above the cross plate 301 increases. At this time, the card cover 302 above the cross plate 301 has a downward movement trend as a whole, so that the tension spring 3023 is elongated. At this time, the tension spring 3023 drives the pull rod 3021 to have a downward movement force, and the pull rod 3021 can drive the connecting rod 303 and the plate 3042 to move downward, and the plate 3042 drives the sealing plug 30 4 contacts with the garage wall 101, and finally completes the extrusion sealing operation, and when the pressing plate 2045 slides horizontally, the pressing plate 2045 can also drive the Z-shaped plate 306 to slide, and the Z-shaped plate 306 drives the blocking block 3061 to slide into the sealing groove 2012, which plays a secondary sealing effect, and the side wall of the cross plate 301 drives the push rod 3051 to move downward, and the push rod 3051 moves downward along the side plate 305, and the push rod 3051 finally contacts with the positioning protrusion 1011, and cooperates with the shovel plate 2041, so as to achieve the purpose of secondary locking and improve the stability and tightness of the connection.

[0026] like Figures 1 to 9 As shown, in a specific embodiment, a partition 1012 is installed on the garage wall 101, the top height of the partition 1012 is greater than the upper surface height of the garage wall 101, and a groove 2011 is opened inside the positioning cover 201, and the size of the groove 2011 is adapted to the size of the partition 1012. When the positioning cover 201 is installed on the garage wall 101 as a whole, the partition 1012 and the groove 2011 need to be aligned with each other, so as to achieve the purpose of assembly.

[0027] like Figures 1 to 9 As shown, further, a rotating rod 2021 is installed on the rotating disk 202, and the rotating rod 2021 movably penetrates the inner wall of the positioning cover 201, a knob 2022 is installed on the top of the rotating rod 2021, and a positioning block 2023 is installed on the side wall of the rotating disk 202. The side wall of the positioning block 2023 fits with the blocking protrusion 2024 installed inside the positioning cover 201, and the distance from the blocking protrusion 2024 to the center of the rotating disk 202 is greater than the radius of the rotating disk 202. The author needs to turn the knob 2022 to drive the rotating rod 2021 to rotate. At this time, the rotating rod 2021 can drive the rotating disk 202 to rotate, and the positioning block 2023 on the side wall of the rotating disk 202 is separated from the blocking protrusion 2024 at this time, wherein the blocking protrusion 2024 serves the purpose of limiting.

[0028] Embodiment 2: The difference between the above embodiment and this embodiment is that: Figures 1 to 9As shown, a reset rod 2061 is rotatably installed on the turntable 202, a baffle 2063 is installed at the end of the reset rod 2061, a reset cover 206 is slidably provided on the side wall of the baffle 2063, the outer shell of the reset cover 206 is rotatably connected to the positioning cover 201, the extension line of the reset cover 206 and the reset rod 2061 does not intersect with the rotation center of the turntable 202, a reset spring 2062 is clamped between the inner wall of the reset cover 206 and the baffle 2063, and the reset spring 2062 is sleeved on the reset rod 2061. The reset spring 2062 is always in a stretched state, so the reset rod 2061 always has a force pushing outward. When the turntable 202 rotates, the force of the reset rod 2061 blocks the rotation. When the position of the connection point between the surface of the turntable 202 and the reset rod 2061 changes, when the connection point moves to the right side of the turntable 202, the reset rod 2061 has a force to drive the turntable 202 to rotate. This force ensures that the turntable 202 will not automatically reset when the turntable 202 is not subject to external force.

[0029] like Figures 1 to 9 As shown, in a specific embodiment, a slide plate 2042 is installed on the top of the vertical plate 204, a guide rod 2043 is movably installed on the side wall of the slide plate 2042, guide seats 2044 are installed at both ends of the guide rod 2043, and the guide seats 2044 are welded to the positioning cover 201. When the vertical plate 204 slides, the vertical plate 204 slides along the guide rod 2043, and the guide rod 2043 limits the entire moving path.

[0030] like Figures 1 to 9As shown, further, a limiting slot 2053 is provided on the vertical plate 204, and the limiting slot 2053 is a through slot. A limiting slider 2052 is slidably arranged inside the limiting slot 2053, and a limiting rod 2054 is installed inside the limiting slider 2052, and both ends of the limiting rod 2054 are installed on the side walls of the limiting slot 2053. A limiting spring 2055 is sleeved on the limiting rod 2054, and one end of the limiting spring 2055 is clamped on the side wall of the limiting slot 2053, and the other end of the limiting spring 2055 is clamped on the limiting slider 2052. One end of the limiting slider 2052 is connected to the pressure plate 2045, and the other end of the limiting slider 2052 is connected to the extrusion rod 205. A guide slider 2051 is installed on the top of the extrusion rod 205, and the guide slider 2051 is slidably connected to the combined groove 203. When the guide slider 2051 moves to the pull-down groove 2032 as a whole, the guide function of the lifting block 2033 can drive the guide slider 2051 to slide downward as a whole, and then drive the bottom limit slider 2052 to slide inside the limit slide groove 2053 through the extrusion rod 205. The limit slider 2052 slides inside the limit rod 2054 and compresses the limit spring 2055 at the bottom, which facilitates the reset operation later. When the limit slider 2052 slides downward, the limit slider 2052 can drive the pressure plate 2045 of the side wall to move toward the positioning protrusion 1011, and the shovel plate 2041 and the pressure plate 2045 cooperate to finally achieve the purpose of fixed locking.

[0031] Embodiment 3: The difference between the above embodiment and this embodiment is that: Figures 1 to 9As shown, a pull plate 3022 is slidably provided inside the card cover 302, one end of the pull plate 3022 is connected to the pull rod 3021, and a tension spring 3023 is connected between the other end of the pull plate 3022 and the side wall of the card cover 302, and the stretching direction of the tension spring 3023 and the moving direction of the pull rod 3021 are in the same straight line. A connecting seat 3031 is installed at the bottom of the connecting rod 303, and the connecting seat 3031 is rotatably connected to the end of the pull rod 3021. The connecting rod 303 is slidably connected to the notch 3033 opened inside the positioning cover 201, and a slide rail 3032 is slidably provided on the top of the connecting rod 303, and the slide rail 3032 is installed on the flat plate 3042, and a positioning rod 3043 is movably installed on the flat plate 3042, and the positioning rod 3043 is installed in the inner cavity of the positioning cover 201. When the pressing plate 2045 moves downward vertically, the fixing seat 3011 can be driven to move downward, and the cross plate 301 on the fixing seat 3011 moves downward at this time, and finally the bottom of the cross plate 301 contacts the positioning protrusion 1011, and then the cross plate 301 is squeezed to rotate, and the angle above the cross plate 301 becomes larger, and a card cover 302 is installed at the end of the cross plate 301. At this time, the connection position of the cross plate 301 at the end of the card cover 302 is changed, and the connection point slides downward at this time, so that the overall height of the card cover 302 is shortened, and the card cover 302 is now When the tension spring 3023 is pulled, the tension spring 3023 pulls the pull plate 3022 with a downward force, the pull plate 3022 drives the pull rod 3021 to move, and the pull rod 3021 drives the connecting seat 3031 with a downward force, and the connecting rod 303 on the top of the connecting seat 3031 can drive the flat plate 3042 to move downward. At this time, the flat plate 3042 slides on the positioning rod 3043, and the flat plate 3042 drives the connecting plate 3041 and the sealing plug 304 to move downward. The sealing plug 304 can fit with the garage wall 101 at this time, and finally complete the sealing operation of the two.

[0032] like Figures 1 to 9As shown, further, a strip groove 3056 is provided on the side wall of the cross plate 301, a slide bar 3055 is slidably provided on the strip groove 3056, a vertical rod 3054 is installed on the side wall of the slide bar 3055, the bottom of the vertical rod 3054 is connected to the push rod 3051, and the push rod 3051 is in a vertical state. A limit plate 3052 is installed on the top of the push rod 3051, and a compression spring 3053 is sleeved on the surface of the push rod 3051, one end of the compression spring 3053 is clamped on the surface of the side plate 305, and the other end of the compression spring 3053 is clamped on the lower surface of the limit plate 3052. When the cross plate 301 rotates, the height of the strip groove 3056 on the cross plate 301 changes, and the sliding bar 3055 on the strip groove 3056 slides inside and presses down the sliding bar 3055, and the vertical rod 3054 driven by the sliding bar 3055 moves downward, and the vertical rod 3054 drives the push rod 3051 to slide downward along the side plate 305, and finally the push rod 3051 and the positioning protrusion 1011 are squeezed, and at this time, the purpose of secondary fixation is achieved through the mutual cooperation between the end of the push rod 3051 and the shovel plate 2041. When the push rod 3051 moves downward, the limit plate 3052 on the push rod 3051 moves downward, and the compression spring 3053 can be compressed at this time, and the compression spring 3053 is used to facilitate the later reset.

[0033] The implementation principle of the anti-leakage structure of the post-cast belt of an underground garage in this embodiment is as follows: When a leak-proof operation is required, the operator can install the positioning cover 201 as a whole onto the garage wall 101. At this time, the partition plate 1012 and the groove 2011 need to be aligned with each other to achieve the purpose of assembly.

[0034] Then the operator needs to turn the knob 2022 to drive the rotating rod 2021 to rotate. At this time, the rotating rod 2021 can drive the rotating disk 202 to rotate, and the positioning block 2023 on the side wall of the rotating disk 202 is separated from the blocking protrusion 2024, wherein the blocking protrusion 2024 serves the purpose of limiting.

[0035] The position of the combination groove 203 on the turntable 202 changes, and first the guide slider 2051 slides on the expansion groove 2031. Then, the guide slider 2051 drives the extrusion rod 205 to slide horizontally, and the extrusion rod 205 drives the entire vertical plate 204 to slide horizontally to both sides, and finally the shovel plate 2041 at the bottom of the vertical plate 204 slides to the bottom of the positioning protrusion 1011, and when the vertical plate 204 slides, the vertical plate 204 slides along the guide rod 2043, and the guide rod 2043 limits the entire moving path.

[0036] When the guide slider 2051 moves to the pull-down groove 2032 as a whole, the guide function of the lifting block 2033 can drive the guide slider 2051 to slide downward as a whole, and then drive the bottom limit slider 2052 to slide inside the limit slide groove 2053 through the extrusion rod 205. The limit slider 2052 slides inside the limit rod 2054 and compresses the limit spring 2055 at the bottom, which facilitates the reset operation later. When the limit slider 2052 slides downward, the limit slider 2052 can drive the pressure plate 2045 of the side wall to move toward the positioning protrusion 1011, and the shovel plate 2041 and the pressure plate 2045 cooperate to finally achieve the purpose of fixed locking.

[0037] When the pressing plate 2045 moves downward vertically, the fixing seat 3011 can be driven to move downward, and the cross plate 301 on the fixing seat 3011 moves downward at this time, and finally the bottom of the cross plate 301 contacts the positioning protrusion 1011, and then the cross plate 301 is squeezed to rotate, and the angle above the cross plate 301 becomes larger, and a card cover 302 is installed at the end of the cross plate 301. At this time, the connection position of the cross plate 301 at the end of the card cover 302 is changed, and the connection point slides downward at this time, so that the overall height of the card cover 302 is shortened, and the card cover 302 is now When the tension spring 3023 is pulled, the tension spring 3023 pulls the pull plate 3022 with a downward force, the pull plate 3022 drives the pull rod 3021 to move, and the pull rod 3021 drives the connecting seat 3031 with a downward force, and the connecting rod 303 on the top of the connecting seat 3031 can drive the flat plate 3042 to move downward. At this time, the flat plate 3042 slides on the positioning rod 3043, and the flat plate 3042 drives the connecting plate 3041 and the sealing plug 304 to move downward. The sealing plug 304 can fit with the garage wall 101 at this time, and finally complete the sealing operation of the two.

[0038] When the vertical plate 204 slides horizontally, the pressure plate 2045 on the side wall of the vertical plate 204 can slide horizontally, and the pressure plate 2045 can drive the Z-shaped plate 306 to slide outward, while the blocking block 3061 slides synchronously. The blocking block 3061 can slide into the sealing groove 2012, so that the blocking block 3061 is located on the surface of the sealing groove 2012 and the partition 1012, thereby achieving a secondary sealing effect.

[0039] When the cross plate 301 rotates, the height of the strip groove 3056 on the cross plate 301 changes, and the sliding bar 3055 on the strip groove 3056 slides inside and presses down the sliding bar 3055, and the vertical rod 3054 driven by the sliding bar 3055 moves downward, and the vertical rod 3054 drives the push rod 3051 to slide downward along the side plate 305, and finally the push rod 3051 and the positioning protrusion 1011 are squeezed, and at this time, the purpose of secondary fixation is achieved through the mutual cooperation between the end of the push rod 3051 and the shovel plate 2041. When the push rod 3051 moves downward, the limit plate 3052 on the push rod 3051 moves downward, and the compression spring 3053 can be compressed at this time, and the compression spring 3053 is used to facilitate the later reset.
