Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a disc-lock type self-locking lower support structure for scaffolding. Background Technology

[0002] Disc-lock scaffolding is a new type of scaffolding system, named for the disc-locking method used to connect its main components, horizontal bars and vertical bars. It is widely used in various construction projects. The scaffolding underpinning is the core load-bearing and adjustment component of the scaffolding support system. It is mainly installed at the bottom of the scaffolding uprights to connect the uprights to the foundation (such as the ground, floor slabs, or wooden blocks). By adjusting the height, it can achieve horizontal leveling of the scaffolding, bear vertical loads, and transfer them to the foundation structure.

[0003] Current scaffolding supports are typically made by directly connecting threaded rods to sleeve rods, which has low fault tolerance. Damage to the threads will cause failure, insufficient safety redundancy, and poor adaptability. They can only form a one-to-one fixed fit relationship and are not compatible with cross-specification systems. Utility Model Content

[0004] The purpose of this utility model is to provide a disc-lock type self-locking lower support structure for scaffolding, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a disc-lock type scaffold self-locking lower support structure, including a support screw and a telescopic assembly. The telescopic assembly is installed on the top of the support screw. The telescopic assembly includes a movable sleeve rod threadedly connected to the outer side of the top of the support screw. A limiting sleeve rod is inserted into the bottom upper surface of the movable sleeve rod through a slot. A fixing screw rod is threadedly connected to one bottom side of the limiting sleeve rod. A lever is fixedly connected to one bottom side of the movable sleeve rod. A limiting toothed ring is fixedly connected to the other bottom side of the movable sleeve rod.

[0006] Preferably, a support sleeve is fitted on the outer side of the limiting sleeve, the bottom of the support sleeve abuts against the movable sleeve, and a connecting disc is threaded to the top of the support sleeve.

[0007] Preferably, a limiting frame is fixedly connected to the bottom of the outer wall of the support sleeve rod, and a limiting tooth block is slidably connected to the inner side of the limiting frame through a slot. An adjusting screw is threadedly connected to the top inner side of the limiting tooth block, and one end of the adjusting screw and the limiting frame form a rotating structure through a slot.

[0008] Preferably, a support plate is fixedly connected to the bottom end of the support screw, and an inclined support plate is fixedly connected to the outer side of the bottom of the support screw, with the bottom of the inclined support plate fixedly connected to the support plate.

[0009] Preferably, the outer side of the support plate is rotatably connected to an extension leg via a shaft, and the inside of the extension leg is slidably connected to an insert block via a slot. Locking screws are threadedly connected to both sides of the insert block.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. A detachable sleeve shaft structure is provided between the support screw and the support sleeve rod through a telescopic component. When thread damage occurs, the damaged sleeve shaft structure can be quickly removed and replaced separately, reducing maintenance costs and the risk of failure due to thread damage. The safety redundancy is higher. The sleeve shaft can be designed as a variable diameter adaptable structure, compatible with multiple thread sizes, improving adaptability and expanding the scope of application. Height adjustment is achieved through the threaded connection between the movable sleeve rod and the support screw rod. The support sleeve rod is inserted into the top of the movable sleeve rod, and then the limiting sleeve rod is slid into the support sleeve rod and inserted into the movable sleeve rod. After that, the movable sleeve rod and the limiting sleeve rod are connected through the fixed screw rod to form a detachable sleeve shaft structure. The connecting plate seals the top of the support sleeve rod and provides connection support with other scaffolding structures. By rotating the adjusting screw, the limiting tooth block moves horizontally in the groove of the limiting frame, so that the limiting tooth block abuts against the groove of the limiting tooth ring, thereby facilitating the synchronous locking of the support sleeve rod and the sleeve shaft structure, enhancing practicality. The lever allows the user to easily apply force to rotate the sleeve shaft structure.

[0011] 2. By rotating the extension legs, the ground support is expanded, enhancing the stability of the bottom support. The insert block slides inside the extension legs and is inserted into the slot on the outside of the support plate, achieving a stable connection between the support plate and the extension legs. The locking screw passes through the slot of the extension legs and is threadedly connected to the insert block to fix the position. Attached Figure Description

Detailed Implementation

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-8 As shown, a disc-lock type scaffolding self-locking support structure includes a support screw 1 and a telescopic assembly 2. The telescopic assembly 2 is installed on the top of the support screw 1. The telescopic assembly 2 includes a movable sleeve 201 threadedly connected to the outer side of the top of the support screw 1. A limiting sleeve 202 is inserted into the bottom upper surface of the movable sleeve 201 through a slot. A fixed screw 203 is threadedly connected to one bottom side of the limiting sleeve 202. A lever 204 is fixedly connected to one bottom side of the movable sleeve 201, and a limiting toothed ring 205 is fixedly connected to the other bottom side of the movable sleeve 201. The telescopic assembly 2 provides a detachable sleeve shaft structure between the support screw 1 and the support sleeve 206. When thread damage occurs, only... The ability to quickly disassemble and replace damaged sleeve structures reduces maintenance costs and the risk of failure due to thread damage, offering higher safety redundancy. The sleeve can be designed as a variable diameter adaptable structure, compatible with multiple thread sizes to improve adaptability and expand its application range. Height adjustment is achieved by threading the movable sleeve rod 201 to the support screw rod 1. The support sleeve rod 206 is inserted into the top of the movable sleeve rod 201, and then the limiting sleeve rod 202 is slid into the support sleeve rod 206 and inserted into the movable sleeve rod 201. The fixed screw rod 203 connects the movable sleeve rod 201 and the limiting sleeve rod 202 to form a detachable sleeve structure. The lever 204 allows the user to apply force to rotate the sleeve structure.

[0016] Furthermore, a support sleeve 206 is fitted on the outer side of the limiting sleeve 202. The bottom of the support sleeve 206 abuts against the movable sleeve 201. A connecting plate 207 is threadedly connected to the top of the support sleeve 206. The connecting plate 207 closes the top of the support sleeve 206 and provides connection support to other scaffolding structures.

[0017] Furthermore, a limiting frame 208 is fixedly connected to the bottom of the outer wall of the support sleeve 206. A limiting tooth block 209 is slidably connected to the inner side of the limiting frame 208 through a slot. An adjusting screw 210 is threadedly connected to the top inner side of the limiting tooth block 209. One end of the adjusting screw 210 and the limiting frame 208 form a rotating structure through a slot. By rotating the adjusting screw 210, the limiting tooth block 209 is moved horizontally within the slot of the limiting frame 208, so that the limiting tooth block 209 abuts against the groove of the limiting tooth ring 205. This facilitates the synchronous locking of the support sleeve 206 and the sleeve shaft structure, enhancing practicality.

[0018] Furthermore, a support plate 3 is fixedly connected to the bottom end of the support screw 1, and an inclined support plate 4 is fixedly connected to the outer side of the bottom of the support screw 1. The bottom of the inclined support plate 4 is fixedly connected to the support plate 3. The surface of the support plate 3 has mounting holes for adding fixing nails to be driven into the ground to enhance structural stability. The inclined support plate 4 provides auxiliary support for the support screw 1 to improve stability.

[0019] Furthermore, an extension leg 5 is rotatably connected to the outer side of the support plate 3 via a shaft. An insert 6 is slidably connected to the inside of the extension leg 5 via a slot. Locking screws 7 are threadedly connected to both sides of the insert 6. By rotating the extension leg 5, the support ground is expanded, enhancing the stability of the bottom support. The insert 6 slides inside the extension leg 5 and is inserted into the slot on the outer side of the support plate 3, thus achieving a stable connection between the support plate 3 and the extension leg 5. The locking screws 7 pass through the slot of the extension leg 5 and are threadedly connected to the insert 6 to fix the position.

[0020] Working principle: In use, firstly, the telescopic component 2 provides a detachable sleeve shaft structure between the support screw 1 and the support sleeve 206. When thread damage occurs, the damaged sleeve shaft structure can be quickly removed and replaced, reducing maintenance costs and the risk of failure due to thread damage, thus increasing safety redundancy. The sleeve shaft can be designed as a variable diameter adaptable structure, compatible with multiple thread sizes, improving adaptability and expanding the scope of application. Height adjustment is achieved through the threaded connection between the movable sleeve 201 and the support screw 1. The support sleeve 206 is inserted into the top of the movable sleeve 201, and then the limiting sleeve 202 is slid into the support sleeve 206 and inserted into the movable sleeve 201. The fixed screw 203 connects the movable sleeve 201 and the limiting sleeve 202 to form a detachable sleeve shaft structure. Secondly, the connecting plate 207 closes the top of the support sleeve 206 and provides access to other scaffolding structures. The connection support is achieved by rotating the adjusting screw 210 to move the limiting tooth block 209 within the slot of the limiting frame 208, so that the limiting tooth block 209 abuts against the groove of the limiting tooth ring 205, thereby facilitating the synchronous locking of the support sleeve rod 206 and the sleeve shaft structure, enhancing practicality. The lever block 204 allows the user to apply force to rotate the sleeve shaft structure. In the third step, the surface of the support plate 3 has mounting holes for adding fixing nails to be driven into the ground to enhance structural stability. The inclined support plate 4 provides auxiliary support for the support screw 1 to improve stability. In the fourth step, the extension leg 5 is rotated to expand the support ground and enhance the stability of the bottom support. The insert block 6 slides within the extension leg 5 and is inserted into the slot on the outside of the support plate 3, achieving a stable connection between the support plate 3 and the extension leg 5. The locking screw 7 passes through the slot of the extension leg 5 and is threadedly connected to the insert block 6 to fix the position. This completes the use of a disc-lock type self-locking lower support structure for scaffolding.
