Description

Technical Field

[0001] This utility model relates to a fastening component, and more particularly to a quick-install fastening component for walls. Background Technology

[0002] In daily life, many items need to be connected and fixed to walls. If the wall surface is uneven, the verticality of the installation will not meet the requirements, especially in bathroom cabinet water tanks. The final result is that the tank is embedded in the wall, so the actual installation needs to be completed before tiling or painting. That is to say, after the bricks are laid, the cabinet water tank is installed, and water pipes and electrical wires are laid at the same time. After these tasks are completed, the wall is leveled, and finally, tiling or painting is done. Therefore, in some special situations, the wall surface is very uneven. In such installation environments, in order to ensure the verticality requirements, installers can only adjust the bolt lengths gradually, such as... Figure 1 As shown, it is necessary to continuously rotate the screw 01 to adjust the distance between the screw 01 and the wall bracket 02, which is time-consuming and labor-intensive, resulting in poor installation efficiency. Utility Model Content

[0003] This utility model provides a quick-installation fastening component for walls, which overcomes the shortcomings of the prior art. The technical solution adopted by this utility model to solve its technical problem is as follows:

[0004] A wall-mounted quick-install fastening assembly includes a screw and a wall bracket. The wall bracket includes a fixing seat for fixing to the wall during installation and a sleeve that engages with the screw. It also includes an adjusting ring and a pressure block. The sleeve has a positioning hole on its side wall. The pressure block is radially movable and positioned in the positioning hole. The pressure block has internal threads that can be screwed into the external threads of the screw. The adjusting ring is axially movable and fitted onto the sleeve. When the adjusting ring moves axially in a first direction to a locking position, it can limit the pressure block within the positioning hole and screw the internal threads of the pressure block into the external threads of the screw. The distance between the sleeve and the screw is adjusted by rotating the screw. When the adjusting ring moves axially in a second direction to an unlocking position, it releases the restriction on the pressure block. The distance between the sleeve and the screw is adjusted by axially pulling the screw or the sleeve.

[0005] In a preferred embodiment: the adjusting ring and the pressure block are provided with mutually paired inclined push surfaces. During the axial movement of the adjusting ring in the first direction, the inclined push surfaces are used to push the pressure block to move radially inward and finally press against the screw.

[0006] In a preferred embodiment: the number of pressure blocks is multiple, evenly distributed at equal intervals along the circumference, and the number of positioning holes is matched one-to-one with the number of pressure blocks.

[0007] In a preferred embodiment: the adjusting ring has a protruding edge on the inner side of the opening in the second direction, and the outer surface of the sleeve has a groove corresponding to the protruding edge. When the adjusting ring moves axially in the first direction to the locking position, the protruding edge is inserted into the groove.

[0008] In a preferred embodiment: the outer surface of the sleeve is provided with a second groove corresponding to the convex edge. When the adjusting ring moves axially in the second direction to the unlocking position, the convex edge is embedded in the second groove, and a peak is formed on the outer surface of the sleeve between the first groove and the second groove.

[0009] In a preferred embodiment, a locking nut is also included. The locking nut has an opening on its side. The locking nut is fastened to or removed from the screw through its opening. When the adjusting ring moves axially in the first direction to the locking position, the locking nut is fastened to the screw and tightened to press the rod sleeve.

[0010] In a preferred embodiment: the fixing base is a plate or sheet structure, in the shape of a V with a 45-degree bend.

[0011] In a preferred embodiment, a connecting block is further included, the connecting block having a through hole through which the screw passes directly, and a countersunk groove for receiving the head of the screw at one end of the through hole, the diameter of the countersunk groove being larger than the diameter of the through hole.

[0012] In a preferred embodiment, a washer and a clamping nut are also included, and the screw passes through the connecting block, the washer, and the clamping nut in sequence before being inserted into the sleeve.

[0013] In a preferred embodiment, the system further includes a reference frame that is hooked onto the rod sleeve. The reference frame has a pressing surface that engages with the fixing seat in the circumferential direction, and the reference frame has a flat upper surface.

[0014] Compared with the prior art, this technical solution has the following advantages:

[0015] The internal thread that connects to the screw is not located on the sleeve, but on the pressure block. Since the pressure block can move radially, the internal thread can be selected to connect with the external thread by controlling the pressure block. In the connected state, the screw cannot move linearly, but can only be axially advanced or de-elevated by rotation to achieve the tightening effect of the thread. When the pressure block is loosened, the internal thread cannot effectively engage with the external thread. At this time, the distance between the sleeve and the screw can be quickly adjusted, thereby improving the installation efficiency. Attached Figure Description

[0026] Please refer to Figures 1 to 9 A wall-mounted quick-install fastening assembly includes a screw 10 and a wall bracket 20. The wall bracket 20 includes a fixing seat 22 for fixing to the wall during installation and a sleeve 24 that engages with the screw. The sleeve 24 is connected to one end of the fixing seat 22, and no threads are required on the side wall of the inner cavity of the sleeve. It also includes an adjusting ring 30 and a pressure block 40. The sleeve 24 has a positioning hole 242 on its side wall, and the pressure block 40 is radially movable and disposed in the positioning hole 242. The side of the pressure block 40 facing the screw has an internal thread that can be screwed into the external thread of the screw 10. The adjusting ring 30 is axially movable and fitted onto the sleeve 24. When the adjusting ring 30 moves axially in a first direction to the locking position (e.g., ...), ... Figure 8(As shown) The pressure block 40 can be limited within the positioning hole 242 and the internal thread of the pressure block 40 can be screwed together with the external thread of the screw 10. At this time, the screw 10 cannot be axially aligned with the sleeve 24, and the distance between the sleeve and the screw can only be adjusted by rotating the screw 10. When the adjusting ring 30 moves axially in the second direction to the unlocked position (e.g.) Figure 7 As shown, the restriction on the pressure block 40 is released, and the distance between the sleeve and the screw is adjusted by axially pulling the screw or the sleeve. That is, when the adjusting ring 30 no longer presses down on the pressure block 40, even if the internal and external threads are in contact, axially pulling the screw can disengage the internal and external threads.

[0027] As described above, when the wall surface is uneven, the adjusting ring 30 can be moved to release the pressure block 40. Then, without turning the screw, the axial movement of the wall bracket 20 can be quickly adjusted so that the fixing seat 22 of the wall bracket 20 is in contact with the wall surface. Then, the adjusting ring 30 can be moved to restrict the pressure block 40. After that, the wall bracket is installed. Only a slight tightening of the bolts is needed to lock the bolts, thus achieving quick installation.

[0028] Preferably, the adjusting ring 30 and the pressure block 40 are provided with mutually matching inclined pushing surfaces. During the axial movement of the adjusting ring 30 in the first direction, the inclined pushing surfaces push the pressure block 40 radially inward and gradually move it until it finally presses against the screw 10. The inclined pushing surfaces enable the adjusting ring and the pressure block to maintain a better contact and tightness, and can also reduce the assembly accuracy requirements between components. However, as long as the machining accuracy is good enough, the inclined pushing surfaces are not necessary. For example, if the inner wall of the adjusting ring has a straight hole structure, the pressure block can still be clamped.

[0029] Preferably, there are multiple pressure blocks 40, evenly distributed at equal intervals along the circumference, and the number of positioning holes 242 is matched one-to-one with the number of pressure blocks. In this embodiment, there are two pressure blocks.

[0030] Preferably, the adjusting ring 30 has a protruding edge 32 on the inner side of the opening in the second direction, and the outer surface of the sleeve 24 has a groove 244 corresponding to the protruding edge. When the adjusting ring 30 moves axially in the first direction to the locking position, the protruding edge 32 is inserted into the groove 244. This ensures stable positioning of the adjusting ring 30 on the shaft, meaning the adjusting ring stably presses against the pressure block 40, and the upper limit of the tightening force that the screw 10 can withstand is higher.

[0031] Preferably, the outer surface of the sleeve 24 is further provided with a second groove 246 corresponding to the protruding edge 32. When the adjusting ring 30 moves axially in the second direction to the unlocked position, the protruding edge 32 is embedded in the second groove 246, and a peak 248 is formed on the outer surface of the sleeve between the first groove and the second groove. Thus, during the adjustment process by moving the adjusting ring 30, the protruding edge 32 squeezes past the peak 248 and falls into the first groove 244 or the second groove 246, obtaining a shifting feel.

[0032] Preferably, it also includes a locking nut 50, the side of which has an opening 52. The locking nut 50 is fastened to or removed from the screw rod 10 through its opening 52. When the adjusting ring 30 moves axially in the first direction to the locking position, the locking nut 50 is fastened to the screw rod 10 and tightened to press against the rod sleeve 24 (e.g., Figure 8 As shown in the figure, this will more firmly fix the position of the wall bracket 20.

[0033] Preferably, the fixing base 22 is a plate or sheet structure, in the shape of a V-shape with a 45-degree bend, thereby adapting to installation needs in corner positions (e.g., Figure 9 (As shown).

[0034] Preferably, the device further includes a connecting block 60, which has a through hole 62 through which the screw 10 passes directly. At one end of the through hole, the connecting block 60 has a recess 64 for receiving the head of the screw 10, the diameter of which is larger than the diameter of the through hole 62. The connecting block 60 can be directly embedded into the frame of the object to be installed, making positioning easier and improving overall strength.

[0035] Preferably, the device further includes a washer 70 and a clamping nut 80. The screw 10 passes sequentially through the connecting block 60, the washer 70, and the clamping nut 80 before being inserted into the rod sleeve 24. The washer 70 and the clamping nut 80 can clamp the frame of the object to be installed, making the structure more robust.

[0036] Preferably, it also includes a reference frame 90, which is hooked onto the rod sleeve 24. The reference frame has a pressing surface 92 that engages with the fixing seat 22 in the circumferential direction. At the same time, the reference frame has a flat upper surface 94.

[0037] The following is combined Figures 5 to 8Taking the cabinet water tank as an example, let me introduce the installation steps. Two wall quick-install fastening components are used. The left and right side frames of the cabinet water tank are connected to the wall at the top by a wall quick-install fastening component. First, the connecting block 60 is inserted into the frame of the cabinet water tank, and the connecting block 60 is fixed to the frame of the cabinet water tank using the clamping nut 80. Then, the cabinet water tank is placed against the wall, with its lower end supported on the ground. Due to the unevenness of the wall surface, the wall bracket 20 may be too close to the wall or too far away; it is also possible that it is just touching the wall. The figure shows an example where the wall bracket 20 is too far from the wall. Next, the adjusting ring 30 is moved to the unlocked position, and the wall bracket 20 is pushed towards the wall so that the fixing seat 22 of the wall bracket is against the wall. The upper surface 94 of the reference frame 90 can be observed and adjusted to be level, thus ensuring that the fixing seat 22 is installed horizontally. Next, the adjusting ring 30 is moved to the locked position, fixing the fixing seat 22 of the wall bracket 20 to the wall, and the verticality of the cabinet water tank is finely adjusted by rotating the screw 10. Finally, the locking nut 50 is locked. Of course, the above installation steps are just an example and are not limited to this.

[0038] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
