Description

Technical Field

[0001] This utility model relates to the field of fastening connectors, and in particular to a novel expansion tube suitable for various wall structures. Background Technology

[0002] Existing expansion tubes are typically used in conjunction with screws to fix or install brackets or panels on walls. Current expansion tubes achieve a tight fit by retracting an annular groove or by combining the retraction of the annular groove with a narrow hole in the tube wall, allowing the tube to expand and be knotted. However, the retraction of the annular groove in existing expansion tubes results in a small contact area between the expansion tube and the hole wall, or the retraction of the annular groove and the narrow hole make it difficult to twist and knot the expansion tube, thus limiting its applicability to various wall types. Utility Model Content

[0003] The purpose of this invention is to provide an expansion tube suitable for various wall types, which is easy to expand or twist and knot, and can be expanded or expanded and knotted according to different wall types, with a simple processing procedure. This aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel expansion tube suitable for multiple walls includes a pipe opening, a hollow deformation section, and a tail end arranged sequentially along the length of the expansion tube; the hollow deformation section includes a connecting section arranged opposite each other, a shaped strip hole provided on each side of the connecting section along the length of the connecting section, and an expansion knotting strip provided in each of the shaped strip holes, the expansion knotting strip being expanded or knotted according to different wall types; at least one rib is provided on the inner wall of the hollow deformation section along the length direction.

[0006] Preferably, the irregularly shaped perforations are similar to continuous rhomboid perforations.

[0007] Furthermore, multiple ribs are provided on the inner wall of the hollow deformable section, wherein the multiple ribs are provided on the inner wall of the connecting section or the inner wall of the expansion knot strip or on the inner wall of the connecting section and the inner wall of the expansion knot strip.

[0008] Furthermore, several conical protrusions are provided on the edges of the irregular strip holes on both sides of the connecting section or on the bulging knot strip.

[0009] Furthermore, a pair of T-shaped expansion lobes are provided opposite each other at the tail end.

[0010] Preferably, the outer peripheral wall of the T-shaped expansion flap is provided with a plurality of teeth.

[0011] The beneficial effects of this utility model are as follows: by providing a shaped strip hole on each side of the connecting section along the length of the connecting section and providing an expansion knot strip in each shaped strip hole, and providing ribs along the length of the inner wall of the hollow deformation section, it is convenient for the expansion knot strip to expand or expand and twist to tie; at the same time, when encountering a cement wall or solid wall, the expansion knot strip expands and drives the expansion tube body to fit tightly with the pre-embedded hole; when encountering a hollow brick wall, the expansion knot strip expands and twists to tie, driving the expansion tube to expand and tie to fill more hollow brick space, so that the expansion tube body fits tightly with the pre-embedded hole.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be further described clearly and completely below in conjunction with the embodiments of this utility model. It should be noted that the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] It should be understood that the terms "upper", "lower", "front", "back", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Example 1, as Figures 1-3 As shown, the present invention provides a novel expansion tube 1 applicable to multiple walls, comprising a tube opening 11, a hollow deformation section 12, and a tail end 13 arranged sequentially along the length of the expansion tube.

[0024] Among them, such as Figure 2 As shown, the hollow deformable section 12 includes a connecting section 121 arranged opposite to each other, a shaped strip hole 122 on each side of the connecting section along the length direction of the connecting section, and an expansion knot strip 123 in each shaped strip hole. The expansion knot strip is expanded or expanded and knotted according to different wall types. At least one rib 124 is provided on the inner wall of the hollow deformable section along the length direction.

[0025] Preferably, such as Figure 1 As shown, the irregular strip hole 122 is a continuous diamond-shaped strip hole. More preferably, the diamond-shaped strip holes are arranged relatively symmetrically. The diamond-shaped strip holes make it easy for the expansion knotting strip to twist and knot along the spiral torque when the expansion tube is knotted.

[0026] Preferably, such as Figure 3 As shown, multiple ribs (124, 125) are provided on the inner wall of the hollow deformation section 12. Among them, the ribs 124 provided on the inner wall of the connecting section or the ribs 125 provided on the inner wall of the expansion knot strip or the connecting section and the inner wall of the expansion knot strip can enhance the strength of the expansion tube wall when it expands and knots.

[0027] Example 2, as Figure 4 As shown, based on Embodiment 1, several conical protrusions 126 are provided on the edge of the irregular strip hole on both sides of the connecting section or on the expansion knot strip, which ensures a larger contact area and a tighter fit between the outer wall of the expansion tube and the inner wall of the reserved hole. At the same time, when encountering a hollow brick wall, the cavity for filling the hollow brick is increased, making the fixing or installation of the expansion tube and screw assembly more secure.

[0028] Example 3, as Figure 5-6 As shown, based on the aforementioned Embodiment 1 or Embodiment 2, a pair of similar T-shaped expansion flaps 131 are provided at the tail end. When the connecting section expands or expands and knots, the expansion flaps at the tail end expand, so that the expansion tube has a larger contact area and a tighter fit with the inner wall of the reserved hole along its overall length.

[0029] Example 4, as Figure 7 As shown, based on the aforementioned embodiment three, a number of teeth 132 are provided on the outer peripheral wall of the T-shaped expansion flap 131, which strengthens the T-shaped expansion flap and increases the cavity to fill the hollow brick when it encounters a hollow brick wall, making the fixing or installation of the expansion tube and screw assembly more secure.

[0030] like Figure 8 As shown, the novel embodiments one to four described above are applicable to the use of expansion tubes 1 and screws 2 in combination in multi-wall applications.

[0031] This utility model discloses a novel expansion tube applicable to multiple walls. It features a shaped slot on each side of a connecting section along its length, with an expansion knotting strip within each slot. Ribs are also installed along the length of the inner wall of the hollow deformation section. These ribs facilitate the expansion and twisting of the knotting strips. When encountering a cement or solid wall, the expansion knotting strips expand, causing the expansion tube to fit tightly against the pre-embedded hole. When encountering a hollow brick wall, the expansion knotting strips expand and twist, causing the expansion tube to expand and fill more of the hollow brick space, ensuring a tight fit between the expansion tube and the pre-embedded hole.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
