Description

Technical Field

[0001] This utility model relates to nuts and wall mounting brackets, and in particular to a quick-release nut and a quick-install wall mounting bracket. Background Technology

[0002] Wall-mounted brackets are used to fix objects (such as cabinet water tanks, washbasins, wall-mounted toilets, etc.) to the wall. They include brackets for connecting to the wall, bolts for connecting the brackets and the objects, and two nuts for tightening the brackets and objects. The nuts and bolts must be threaded together to achieve a tightening effect. Traditionally, nuts are screwed in gradually from the initial end of the bolt. Similarly, when tightening the brackets and objects, installers need to rotate the nuts one turn at a time. Therefore, the slow screwing in and out of the nuts significantly affects the efficiency of assembly and disassembly.

[0003] To improve assembly and disassembly efficiency, C-nuts have appeared on the market. C-nuts can be directly engaged with the bolt at any position through their opening, and then only a slight rotation is needed to tighten the bracket / object, thus greatly reducing the travel distance of the rotating nut. However, the tightening process requires great care. Once the C-nut has tightened the bracket / object and cannot move further, further rotation of the C-nut will cause excessive pressure, leading to outward expansion and deformation of the C-nut, eventually causing it to slip and lose connection with the bolt. In other words, when C-nuts are used with bolts to tighten brackets / objects, they are prone to stripping or disengaging, or rather, the firmness of the C-nut in tightening / clamping the bracket / object is quite limited. Utility Model Content

[0004] This utility model provides a quick-release nut and a quick-install wall bracket, which overcomes the shortcomings of the prior art. The technical solution adopted by this utility model to solve its technical problem is as follows:

[0005] The quick-release nut has a C-shaped threaded hole that can be screwed onto a screw rod. The opening size of the C-shaped threaded hole is slightly smaller than the diameter of the screw rod, and the screw rod can forcefully enter or exit the C-shaped threaded hole through the opening. It also has a clearance hole that communicates with the opening of the C-shaped threaded hole. The outer wall of the quick-release nut is closed in the circumferential direction. The quick-release nut can be hung on the screw rod through the clearance hole, and the clearance hole and the screw rod are in clearance fit.

[0006] In a preferred embodiment: at least one end face is provided with an arc-shaped limiting groove concentric with the C-shaped threaded hole around the periphery of the C-shaped threaded hole.

[0007] In a preferred embodiment: each thread on the inner wall of the C-shaped threaded hole is a sharpened guide triangle shape at both ends.

[0008] In a preferred embodiment: each thread on the inner wall of the C-shaped threaded hole is divided into multiple segments arranged at intervals.

[0009] In a preferred embodiment: the width of the clearance hole gradually increases outward from the opening side of the C-shaped threaded hole.

[0010] In a preferred embodiment, the quick-release nut is a one-piece molded plastic part.

[0011] In a preferred embodiment, the outer side wall of the quick-release nut is provided with a plurality of protrusions at intervals.

[0012] A wall-mounted quick-install bracket includes a wall bracket, a screw, and a quick-locking clip. The wall bracket includes a base plate and a hollow column connected together. The screw and the hollow column are axially telescopically connected. The quick-locking clip is movably mounted on the hollow column. When the quick-locking clip moves radially in a first direction to the locking position, it engages with the screw. When the quick-locking clip moves radially in a second direction to the unlocking position, it disengages from the screw. The bracket also includes a quick-release nut.

[0013] The quick-release nut is provided with a C-shaped threaded hole that can be screwed onto the screw rod. The opening size of the C-shaped threaded hole is slightly smaller than the diameter of the screw rod, and the screw rod can forcefully enter or exit the C-shaped threaded hole through the opening. The quick-release nut is also provided with a clearance hole that communicates with the opening of the C-shaped threaded hole. The outer wall of the quick-release nut is closed in the circumferential direction. The quick-release nut can be hung on the screw rod through the clearance hole, and the clearance hole and the screw rod are in clearance fit. The quick-release nut is fitted onto the screw rod. During installation, the quick-release nut is screwed onto the screw rod and presses against the end face of the hollow column.

[0014] In a preferred embodiment: the end face of the quick-release nut facing the hollow column is provided with an arc-shaped limiting groove concentric with the C-shaped threaded hole around the C-shaped threaded hole, and the end face of the hollow column is provided with a limiting protrusion corresponding to the arc-shaped limiting groove. When the quick-release nut presses against the end face of the hollow column, the arc-shaped limiting groove and the limiting protrusion are inserted together.

[0015] In a preferred embodiment, a connecting block is also included. The number of quick-release nuts is two. The bolt passes through the connecting block and the two quick-release nuts in sequence and is then inserted into the hollow column. During installation, one quick-release nut presses against the hollow column, and the other quick-release nut locks the connecting block.

[0016] Compared with the prior art, this technical solution has the following advantages:

[0017] 1. The quick-release nut uses a C-shaped threaded hole to achieve quick loading and unloading with the screw. At the same time, the outer wall is closed in the circumferential direction and has a similar shape to a regular nut. This can limit the opening deformation and expansion of the C-shaped screw hole, thereby effectively preventing the nut from expanding outward and deforming and the bolt from disengaging when tightened. Therefore, the quick-release nut can withstand the same level of tightening force as a regular nut.

[0018] 2. The quick-release nut can be hung on the screw through the clearance hole and moved quickly without falling off, which can prevent the quick-release nut from falling off and being lost.

[0019] 3. The quick-release nut has an arc-shaped limiting groove on its end face. When it approaches the object being locked, the arc-shaped limiting groove can engage with the limiting protrusion on the object being locked, further preventing the quick-release nut from expanding and deforming, thereby further improving its pressure resistance.

[0020] 4. The C-shaped threaded hole has tapered guide triangles at both ends, which makes it easier to connect with the screw and avoids damaging the threads.

[0021] 5. Each thread on the inner wall of the C-shaped threaded hole is divided into multiple segments with intervals, which makes it easier for the screw to enter and exit the C-shaped threaded hole. Attached Figure Description

[0029] Please refer to Figures 1 to 6A quick-install wall bracket includes a quick-release nut 10, a screw 20, a wall bracket 30, and a quick-lock buckle 40. The wall bracket 30 includes a base plate 32 and a hollow column 34 connected together. The screw 20 and the hollow column 34 are axially movable and telescopically inserted. The quick-lock buckle 40 is radially movable on the hollow column 34. The quick-release nut 10 is fitted onto the screw 20. The quick-release nut 10 has a C-shaped threaded hole 12 that can be screwed onto the screw 20. The opening size of the C-shaped threaded hole 12 is slightly smaller than the diameter of the screw, and the screw can forcibly enter or exit the C-shaped threaded hole 12 through the opening. That is, under external force, the C-shaped threaded hole 12 of the quick-release nut 10 can be fastened onto the screw 20, or the two can disengage from the snap-lock connection. The quick-release nut 10 also has a clearance hole 14, which communicates with the opening of the C-shaped threaded hole 12. The outer wall of the quick-release nut 10 is closed in the circumferential direction. The quick-release nut 10 can be hung on the screw 20 through the clearance hole 14, and the clearance hole 14 and the screw 20 are in clearance fit, that is, the size of the clearance hole 14 is larger than that of the screw 20. Therefore, if the screw 20 exits the C-shaped threaded hole 12 and enters the clearance hole 14, the quick-release nut 10 can be translated linearly along the screw 20. If the screw 20 enters the C-shaped threaded hole 12, the screw 20 is screwed into the quick-release nut 10.

[0030] During installation, when the quick-lock buckle 40 moves radially in the second direction to the unlock position, it disengages from the screw 20. The screw 20 retracts to the clearance hole 14. Then, the extension and retraction of the screw 20 and the hollow column 34 are adjusted. Next, the quick-lock buckle 40 moves radially in the first direction to the locking position and engages with the screw 20, thereby fixing the screw 20 and the hollow column 34 in an axial position. Finally, the quick-release nut 10 is moved toward the hollow column 34. After reaching the hollow column 34, the quick-release nut 10 is pushed to allow the screw 20 to enter the C-shaped threaded hole 12. The quick-release nut 10 is then turned to bring it close to and press against the hollow column 34.

[0031] Preferably, the end face of the quick-release nut 10 facing at least one side of the hollow column 34 is provided with an arc-shaped limiting groove 16 concentric with the C-shaped threaded hole 12 around the C-shaped threaded hole 12, and the end face of the hollow column 34 is provided with a limiting protrusion 342 corresponding to the arc-shaped limiting groove. When the quick-release nut 10 presses against the end face of the hollow column 34, the arc-shaped limiting groove 16 and the limiting protrusion 342 are inserted together.

[0032] Preferably, each thread 122 on the inner wall of the C-shaped threaded hole 12 has a tapered guide triangle shape at both ends. (See attached diagram) Figure 3As can be seen, in this embodiment, there are a total of four threads 122, and the opening ends are all sharpened guide triangle shapes.

[0033] Preferably, each thread 122 on the inner wall of the C-shaped threaded hole 12 is divided into multiple segments arranged at intervals. In this embodiment, it is divided into two segments.

[0034] Preferably, the width of the relief hole 14 gradually expands outward from the opening side of the C-shaped threaded hole 12, thus forming a trumpet shape.

[0035] Preferably, the quick-release nut 10 is a one-piece molded plastic part.

[0036] Preferably, the outer side wall of the quick-release nut 10 is provided with a plurality of protrusions 18 at intervals.

[0037] Preferably, the device also includes a connecting block 50. There are two quick-release nuts 10. The bolt 20 passes through the connecting block 50 and the two quick-release nuts 10 in sequence and then inserts into the hollow column 34. During installation, one quick-release nut 10 presses against the hollow column 34, while the other quick-release nut 10 is used to lock the connecting block 50. The connecting block 50 can be embedded into the object being installed. The screw 20 locks the connecting block 50 under the drive of the other quick-release nut 10.

[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.
