Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of building construction auxiliary devices, and in particular to a high-strength waterproof backing board reinforcement device. Background Technology
[0002] As is well known, waterproofing is a crucial aspect of ensuring building quality and lifespan in the modern construction industry. Waterproof backing boards, as an important component of waterproofing systems, are widely used in areas prone to water accumulation such as bathrooms, kitchens, and basements, as well as exterior walls and other areas requiring waterproofing protection. Their main function is to provide a solid supporting foundation for the waterproof layer, enhancing its stability and durability, and preventing moisture from penetrating into the building structure, thereby avoiding structural damage, mold growth, and other problems caused by water erosion.
[0003] Existing waterproof backing boards are mostly fixed to the substrate using common methods such as clips and expansion bolts. However, this method has been found to neglect the dead corners of the waterproof backing board. These areas are far from the central fixing point and lack sufficient support and restraint when subjected to external forces, making them particularly vulnerable and prone to cracking. This reduces the stability of the waterproof backing board and results in poor practicality. Utility Model Content

The right end of the base is connected to the left end of the backing board body via the fixing mechanism, and auxiliary mechanisms are evenly arranged on the left end of the backing board. Each auxiliary mechanism includes an mounting block, a connecting block, a positioning plate, a fixing block, two sets of clamping plates, two sets of first locking blocks, a guide assembly, a telescopic assembly, and a buffer mechanism. The left end of the backing board body is connected to the right end of the fixing block. The left end of the fixing block slides and is fitted to the right end of the connecting block via the buffer mechanism. The left end of the connecting block is connected to the right end of the positioning plate. The base is connected to the left end of the mounting block on the right side. The mounting block has a working cavity with a pre-drilled hole on the right end. The left end of the positioning plate passes through the pre-drilled hole and is tightly attached to the left end of the working cavity of the mounting block. The front and rear ends of the working cavity of the mounting block are connected to one end of the clamping plate through a telescopic component. The left ends of the two sets of clamping plates are slidably attached to the working cavity of the mounting block through a guide component. The opposite ends of the two sets of clamping plates are connected to one end of a set of first locking blocks. The left side of the front and rear ends of the positioning plate is provided with a set of locking slots. The other ends of the two sets of first locking blocks are respectively engaged with a set of positioning plate locking slots.
[0006] Preferably, the telescopic assembly includes multiple sets of damping rods and multiple sets of first springs. The front and rear ends of the working cavity of the fixed block are evenly connected to one end of the multiple sets of damping rods, and one end of the two sets of clamping plates is connected to the other end of the multiple sets of damping rods. A set of first springs is provided on the outer side of each of the multiple sets of damping rods.
[0007] Preferably, the guide assembly includes two sets of guide blocks, and two sets of sliding grooves are evenly provided on the left end of the working cavity of the two sets of mounting blocks. The left ends of the two sets of guide blocks are slidably connected to the sliding grooves of the working cavity of the mounting blocks, and the right ends of the two sets of guide blocks are connected to the left end of a set of clamping plates.
[0008] Preferably, the buffer mechanism includes a slide rod, two sets of second springs, two sets of first sliders, two sets of connecting plates, and a hinge assembly. The left end of the fixed block is provided with a groove, and the right end of the groove of the fixed block is provided with a set of sliding grooves, and the set of sliding grooves is provided with slide rods. The two sets of first sliders are slidably connected through the slide rods and the sliding grooves at the right end of the grooves of the fixed block, respectively.

Simultaneously, the left end of the positioning plate is inserted into the working cavity of the mounting block through the reserved hole until the left end of the positioning plate is tightly fitted with the left end of the working cavity of the mounting block. When the positioning plate slides within the working cavity of the mounting block, it squeezes the two sets of first locking blocks and clamping plates. This causes the two sets of clamping plates to drive the first locking blocks to slide and begin squeezing the telescopic component. When the two sets of slots on the positioning plate align with the first locking blocks, the telescopic component rebounds, causing the two sets of clamping plates to drive the first locking blocks and positioning plate to engage, thus completing the installation. This assists in reinforcing the waterproof backing board, improving its support and constraint effects, thereby enhancing its stability and practicality. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0018] like Figures 1 to 4As shown, this utility model discloses a high-strength waterproof backing board reinforcement device, comprising a base 1, a backing board body 2, a fixing mechanism 3, and four sets of auxiliary mechanisms 4. The right end of the base 1 is connected to the left end of the backing board body 2 via the fixing mechanism 3, and auxiliary mechanisms 4 are evenly arranged on the left end of the backing board. The auxiliary mechanisms 4 include an mounting block 401, a connecting block 402, a positioning plate 403, a fixing block 404, two sets of clamping plates 405, two sets of first locking blocks 406, a guide assembly, a telescopic assembly, and a buffer mechanism. The left end of the backing board body 2 is connected to the right end of the fixing block 404. The left end of the fixed block 404 slides onto the right end of the connecting block 402 via a buffer mechanism. The left end of the connecting block 402 is connected to the right end of the positioning plate 403. One side of the right end of the base 1 is connected to the left end of the mounting block 401. The mounting block 401 is provided with a working cavity. A reserved hole is provided at the right end of the working cavity of the mounting block 401. The left end of the positioning plate 403 passes through the reserved hole and is tightly attached to the left end of the working cavity of the mounting block 401. The front and rear ends of the working cavity of the mounting block 401 are respectively connected to one end of the clamping plate 405 via a telescopic component. The left ends of the two sets of clamping plates 405 are connected to the mounting block 401 via a guide component. The working chamber slides tightly against the substrate. One end of each of the two sets of clamping plates 405 is connected to one end of a set of first locking blocks 406. A set of locking slots is provided on the left side of both the front and rear ends of the positioning plate 403. The other ends of the two sets of first locking blocks 406 are respectively engaged with the locking slots of the positioning plate 403. The installation position of the backing plate is determined on the substrate and marked. The mounting block is fixed to the substrate according to the marked position. Then, the worker connects the backing plate body through the fixing mechanism. Simultaneously, the left end of the positioning plate is inserted into the working chamber of the mounting block through the pre-drilled hole until the left end of the positioning plate is flush with the mounting block. The left end of the working cavity of the block fits tightly. When the positioning plate slides in the working cavity of the installation block, it will squeeze the two sets of first locking blocks and clamping plates. This causes the two sets of clamping plates to drive the first locking blocks to slide and start squeezing the telescopic component. When the two sets of slots of the positioning plate are aligned with the first locking blocks, the telescopic component rebounds, causing the two sets of clamping plates to drive the first locking blocks and positioning plates to lock together, thus completing the installation. This helps to reinforce the waterproof backing plate, improve the support and constraint effect of the waterproof backing plate, and thus improve the stability of the waterproof backing plate, thereby enhancing its practicality.
[0019] As a preferred embodiment of the above, the telescopic assembly includes multiple sets of damping rods 407 and multiple sets of first springs 408. The front and rear ends of the working cavity of the fixing block 404 are evenly connected to one end of the multiple sets of damping rods 407, and one end of each of the two sets of clamping plates 405 is connected to the other end of the multiple sets of damping rods 407. A set of first springs 408 is provided on the outer side of each of the multiple sets of damping rods 407. The two sets of clamping plates drive the first locking block to slide and start to compress the first spring. When the two sets of locking slots of the positioning plate are aligned with the first locking block, the first spring rebounds, causing the two sets of clamping plates to drive the first locking block and the positioning plate to lock together. This allows for quick positioning and locking of the positioning plate, improving the stability of its backing plate and thus enhancing its practicality.
[0020] As a preferred embodiment of the above, the guide assembly includes two sets of guide blocks 409. Two sets of sliding grooves are evenly provided on the left end of the working cavity of the two sets of mounting blocks 401. The left ends of the two sets of guide blocks 409 are slidably connected to the sliding grooves of the working cavity of the mounting blocks 401, and the right ends of the two sets of guide blocks 409 are connected to the left end of a set of clamping plates 405, respectively. This ensures that the clamping plates always maintain linear motion during movement, so that the first locking block can be accurately engaged or disengaged from the positioning plate slot, thus enhancing practicality.
[0021] In a preferred embodiment, the buffer mechanism includes a slide rod 410, two sets of second springs 411, two sets of first sliders 412, two sets of connecting plates 413, and a hinge assembly. A groove is provided at the left end of the fixing block 404, and a set of sliding grooves is provided at the right end of the groove. A slide rod 410 is mounted on these sliding grooves. The two sets of first sliders 412 are slidably connected via the slide rod 410 and the sliding grooves at the right end of the groove in the fixing block 404. The right ends of the two sets of connecting plates 413 are respectively connected to the left ends of the first sliders 412. A set of second springs 411 are provided at both ends of the outer sides of the two sets of slide rods 410. 1. The top and bottom of the two sets of second springs 411 are respectively connected to one end of the slide groove and one end of the second spring 411. The left ends of the two sets of connecting plates 413 are hinged to the right end of the connecting block 402 through the hinge assembly. When subjected to a large external force impact during installation, the buffer mechanism can absorb and disperse the impact force. The second spring buffers the impact force by compression and extension. The first slider slides on the slide rod to adjust the position of the connecting plate. The impact force is dispersed to the fixed block and the connecting block through the hinge assembly, reducing the direct impact on the dead corner of the backing plate and protecting the backing plate from damage, thus enhancing practicality.
[0022] As a preferred embodiment of the above, the hinge assembly includes multiple sets of hinge seats 414 and four sets of support rods 415. The left ends of the two sets of connecting plates 413 are evenly hinged through the two sets of hinge seats 414 and one end of the support rods 415, and the right end of the connecting block 402 is hinged through the other four sets of hinge seats 414 and the other end of the support rods 415. The hinge assembly enables the connecting plates to rotate flexibly when the buffer mechanism is working, better adapting to impact forces in different directions, ensuring that the buffer mechanism can effectively disperse the impact force, improving the buffering effect and adaptability of the buffer mechanism, and thus enhancing its practicality.
[0023] As a preferred embodiment of the above, the four sets of positioning plates 403 are provided with inclined surfaces on the left ends of their front and rear sides; the inclined surfaces can guide the positioning plates to pass smoothly through the reserved holes on the right end of the working cavity of the mounting block, reduce installation resistance, improve installation efficiency, and make the installation of the auxiliary mechanism more convenient, thus enhancing practicality.
[0024] This utility model discloses a high-strength waterproof backing board reinforcement device. During operation, the installation position of the backing board is determined on the substrate and marked. The mounting block is fixed to the substrate according to the marked position. Then, the worker connects the backing board body through a fixing mechanism. Simultaneously, using the inclined surfaces on the left ends of both sides of the positioning plate, the left end of the positioning plate is inserted into the working cavity of the mounting block through a pre-drilled hole until the left end of the positioning plate is tightly fitted with the left end of the working cavity of the mounting block. When the positioning plate slides within the working cavity of the mounting block, it presses against two sets of first locking blocks and clamping plates. This causes the two sets of clamping plates to drive the first locking blocks to slide and press against the first spring. When the two sets of slots on the positioning plate align with the first locking blocks, the first spring rebounds, causing the two sets of clamping plates to drive the first locking blocks and positioning plate into place, thus completing the installation. Before completing the above actions, the device is first moved to the desired position by the user.
