Description

Technical Field

[0001] This utility model relates to the field of wall repair technology, and in particular to an adhesive injection screw device for sealing wall cracks and leaks. Background Technology

[0002] In building walls, especially exterior walls, wind and rain erosion often leads to cracks. If not repaired in time, these cracks will continue to widen. Wall cracks not only cause air and water leaks, but in severe cases, they can also affect the structural strength of the wall, thus increasing the risk of wall collapse. Therefore, timely repair of wall cracks is crucial.

[0003] Existing technologies mostly use glue-injecting screws to fill wall gaps, but existing glue-injecting screw devices are inconvenient to use. They require tightening the screw body first, and then operating the corresponding parts to squeeze out the glue. This process is complicated and time-consuming.

[0004] Based on the above-mentioned shortcomings, a glue-injecting screw device for sealing wall cracks and leaks is proposed. Utility Model Content

[0005] The purpose of this invention is to provide an adhesive injection screw device for sealing wall cracks and leaks, in order to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides a glue-injecting screw device for sealing wall cracks and leaks, comprising a screw-in assembly, multiple telescopic assemblies, and a hollow screw body. The screw body consists of a countersunk section at the top, a glue-injecting section in the middle, and a screw tip section at the bottom. The countersunk section has multiple through holes, and the telescopic assemblies are engaged inside the through holes. The inner side of the telescopic assemblies is fixedly connected to the screw-in assembly. The outer wall of the glue-injecting section is threaded, and the glue-injecting assembly is slidably connected to the inner wall of the glue-injecting section. The glue-injecting assembly is filled with glue material at its bottom, and the bottom of the screw tip section has a glue inlet groove.

[0007] Preferably, the screw-in assembly includes a rotating block and a linkage cap fixedly connected to the bottom of the rotating block. The rotating block is rotatably connected to the inner wall of the glue injection section. A cross-shaped fusion groove is provided at the top of the rotating block. The fusion groove is composed of two groove sections, one long and one short. A prism-shaped inner hole is provided at the bottom of the linkage cap.

[0008] Preferably, the telescopic assembly includes multiple telescopic rods, a push post, and an inclined pressure rod. The fixed end of the telescopic rod is connected to the outer wall of the linkage cap, and the moving end of the telescopic rod is connected to a locking block, which engages in the through hole. A compression spring is provided on the outside of the telescopic rod.

[0009] Preferably, the lower end of the pressure rod is fixedly connected to the outer wall of the countersunk section, the upper end of the pressure rod is fixedly connected to one end of the push column, and the other end of the push column extends into the through hole.

[0010] Preferably, the glue injection assembly includes a sliding plug slidably connected to the inner wall of the glue injection section, and a linkage block is fixedly connected to the top of the sliding plug, the linkage block being adapted to the linkage cap.

[0011] Preferably, a stop block is adhered to the groove of the adhesive.

[0012] Therefore, this utility model provides a glue-injecting screw device for sealing wall cracks and leaks, employing the aforementioned structure. Through the coordinated operation of the telescopic rod and push column, and the linkage cap and linkage block, the insertion of the glue-injecting screw and the injection of glue can be gradually completed by simply rotating the rotating block with a screwdriver. During the screwing process, the rotating block automatically releases its limit and triggers glue injection, eliminating the need for the separate steps of tightening the screw and manually injecting glue in traditional methods. This makes operation convenient and significantly improves construction efficiency.

[0025] Example

[0026] like Figures 1-7 As shown, the present invention discloses a glue-injecting screw device for sealing wall cracks and leaks, comprising a screw-in assembly 4, multiple telescopic assemblies 5, and a hollow screw body. The screw body consists of a countersunk section 1 at the top, a glue-injecting section 2 in the middle, and a screw tip section 3 at the bottom. The outer wall of the countersunk section 1 is a gradually inclined surface with multiple through holes 6. The through holes 6 are preferably arranged in a circumferential array and are perpendicular to the central axis of the screw body. The telescopic assemblies 5 are engaged inside the through holes 6, and the inner side of the telescopic assemblies 5 is fixedly connected to the screw-in assembly 4.

[0027] The screw-in assembly 4 includes a rotating block 41 and a linkage cap 42 fixedly connected to the bottom of the rotating block 41. The rotating block 41 is rotatably connected to the inner wall of the glue injection section 2. In this embodiment, the outer wall of the rotating block 41 is set to be cylindrical. Therefore, in addition to rotating, the rotating block 41 can also slide in the glue injection section 2, which facilitates the rapid advancement of glue injection.

[0028] The top of the rotating block 41 is provided with a cross-shaped fusion slot 43, which is composed of two vertical grooves of different lengths, so as to be compatible with both Phillips and flathead screwdrivers. In this embodiment, the bottom of the linkage cap 42 is provided with a prism-shaped inner hole, preferably in the form of a vertical regular octagon.

[0029] The telescopic assembly 5 includes multiple telescopic rods 51, push rods 52, and inclined pressure rods 53. The fixed end of the telescopic rod 51 is connected to the outer wall of the linkage cap 42, and the moving end of the telescopic rod 51 is connected to a locking block 54, which is engaged in the through hole 6. A compression spring 55 is sleeved on the outside of the telescopic rod 51, and the compression spring 55 is engaged between the locking block 54 and the linkage cap 42. The locking block 54 is used to limit and lock the compression spring 55.

[0030] In the initial stage of screwing in, the compression spring 55 causes the locking block 54 at the end of the telescopic rod 51 to be firmly locked in the locking hole. At this time, it is equivalent to an ordinary screw. Under the action of the screwdriver, the screwing assembly 4 drives the screw body to rotate through the linkage cap 42, telescopic rod 51, and locking block 54, effectively screwing in and embedding it into the wall, thus playing a role in fastening the walls on both sides of the crack.

[0031] The lower end of the pressure rod 53 is fixedly connected to the outer wall of the countersunk section 1, and the upper end of the pressure rod 53 is fixedly connected to one end of the push column 52. The other end of the push column 52 extends into the through hole 6.

[0032] As the screw body continues to rotate, when the screw body is about to be fully embedded in the wall, the pressure rod 53 is squeezed by the wall, which pushes the push post 52 into the locking hole and into the locking block 54. The squeezing of the push post 52 compresses the telescopic rod 51, and finally pushes the telescopic rod 51 out of the locking hole, releasing the restriction on the rotating block 41.

[0033] The outer wall of the injection section 2 is threaded, and the inner wall of the injection section 2 is slidably connected to the injection component 7, which is used to control the injection of adhesive. The injection component 7 includes a sliding plug 71 slidably connected to the inner wall of the injection section 2. It is preferably made of rubber, and the lower end is a frustoconical structure. The bottom is filled with adhesive. The top of the sliding plug 71 is concentrically fixedly connected to a linkage block 72, which is adapted to the linkage cap 42.

[0034] After the limit is released, the rotating block 41 rotates or slides downward under the action of the screwdriver, so that the linkage cap 42 and the linkage block 72 are tightly matched and linked. At this time, the force can be applied to push or rotate the sliding plug 71, so that the sliding plug 71 moves down and squeezes the rubber material below.

[0035] The screw tip 3 has a funnel-shaped structure that converges towards the middle, and a glue outlet groove 8 is provided at the bottom. A stop block 9 is bonded inside the glue outlet groove 8. The stop block 9 can seal the glue outlet groove 8 to prevent the glue from overflowing during transportation.

[0036] As the adhesive is continuously squeezed, the pressure gradually increases, eventually breaking through the baffle 9, and the adhesive fills the gaps in the wall, thus sealing the gaps.

[0037] The working principle of the above-mentioned glue-injecting screw device for sealing wall cracks and leaks is as follows:

[0038] In the initial stage of screwing, the screw body is effectively embedded in the wall under the action of the screwdriver; as the screw is screwed deeper, the telescopic rod 51 automatically releases its limit, and the screwing component 4 pushes the rubber slide 71 down, continuously squeezing the rubber material; as the pressure of the rubber material increases, it eventually breaks through the block 9's seal on the rubber material, filling the gap in the wall and achieving the filling of the wall gap; the whole process only requires inserting the screwdriver into the fusion slot 43 and continuously rotating it, without any extra operations, which is convenient and quick.

[0039] Therefore, this utility model provides a glue-injecting screw device for sealing wall cracks and leaks, employing the aforementioned structure. Through the coordinated operation of the telescopic rod and push column, and the linkage cap and linkage block, the insertion of the glue-injecting screw and the injection of glue can be gradually completed by simply rotating the rotating block with a screwdriver. During the screwing process, the rotating block automatically releases its limit and triggers glue injection, eliminating the need for the separate steps of tightening the screw and manually injecting glue in traditional methods. This makes operation convenient and significantly improves construction efficiency.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
