Description

[0001] This application is a divisional application of the invention patent application filed on April 7, 2026, with application number 2026104494179 and invention title "A concealed positioning device and its installation and positioning method". Technical Field

[0002] This invention relates to an installation positioning tool, and more particularly to a concealed mounting positioning device and its installation positioning method for marking the position of a concealed mounting groove on a wall for an item to be installed. Background Technology

[0003] Currently, many wall-mounted items, such as shelves, mirrors, and cabinets, have concealed hanging slots on their backs. Installation requires drilling holes in the wall and installing hooks before aligning the item's hanging slot with the hooks. However, since the hanging slots are located on the back of the item and are not directly visible during installation, it's difficult to accurately determine the drilling positions for the hooks. Existing positioning methods typically use a measuring tape for estimation, which has significant errors, resulting in items being misaligned or unable to be hung after installation, requiring repeated adjustments—a time-consuming and laborious process.

[0004] Therefore, there is an urgent need for a device and method that can quickly and accurately locate the mounting holes of concealed hanging items. Summary of the Invention

[0005] The purpose of this invention is to provide a concealed hanging positioning device and its installation and positioning method to solve the problems of difficult positioning and large errors when installing concealed hanging items in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A concealed hanging positioning device includes a snap-fit ​​component and a marking forming part. The snap-fit ​​component is adapted to be detachably snapped into a concealed hanging slot of an item to be installed and has a hanging central axis. The marking forming part is used to leave a positioning mark on the wall surface and has a marking central axis that coincides with the hanging central axis.

[0008] It should be noted that the core inventive point of this invention lies in discovering that the geometric relationship of "the mark center axis coinciding with the hook center axis" is the key to achieving WYSIWYG precise positioning. In traditional manual measurement methods, the positioning reference (concealed hanging groove) and the mark reference (mark point) need to be manually measured to establish a correspondence, and errors are unavoidable. This invention, by precisely coinciding the center axis of the mark forming part with the hook center axis of the snap-fit ​​component in geometry, ensures that wherever the device is hung, the mark is applied there, achieving positioning marking without any measurement steps, thus eliminating the source of measurement error in principle. Any concealed hanging positioning device that achieves the coincidence of the mark center axis and the hook center axis, regardless of its specific implementation method, falls within the protection scope of this invention. Under the guidance of the disclosure of this invention, those skilled in the art can use their common knowledge to design various specific structures that satisfy this geometric constraint without creative effort, and these specific structures should all be understood as being fully disclosed and covered by this invention.

[0009] In one embodiment, the device further includes a main body, the snap-fit ​​member is disposed at the top of the main body, the mark forming part is disposed at the bottom of the main body, and the main body is configured to drive the mark forming part to move toward the wall, so that the mark forming part contacts the wall to leave a positioning mark.

[0010] In one embodiment, the device further includes a resilient reset member configured to retract and reset the mark forming portion after the pressing force is released. The resilient reset member may be a helical spring, a sheet spring, or an elastic rubber body.

[0011] It should be noted that there are various variations in the specific implementation of the above-mentioned components, and all of these variations fall within the protection scope of this invention. For example, the mark forming part can be at least one of a sponge, a felt sheet, a photosensitive pad, or a rigid tip; the elastic reset member can be at least one of a coil spring, a spring sheet, or an elastic rubber body. These variations have all been clearly disclosed in the original specification of the parent invention, and those skilled in the art will understand that regardless of the specific variation used, as long as the geometric relationship of the mark center axis coinciding with the hook center axis is satisfied, the WYSIWYG precise positioning effect of this invention can be achieved.

[0012] In one implementation, the snap-fit ​​connector is a replaceable connection to adapt to concealed hanging slots of different sizes.

[0013] In one embodiment, the marking forming part is at least one of sponge, felt, photosensitive pad, or rigid tip. The marking forming part is replaceably connected to the main body of the device, facilitating the replenishment or replacement of marking material.

[0014] This invention also provides a method for using the aforementioned concealed hanging positioning device, comprising the following steps: inserting the snap-fit ​​component into the concealed hanging groove on the back of the item to be installed, so that the device is suspended on the item; moving the item to be installed to the target installation area on the wall; pressing the item towards the wall, so that the marking portion contacts the wall and leaves a positioning mark on the wall; removing the item from the wall, and drilling holes or installing hanging nails according to the positioning mark on the wall. Before pressing, the horizontal position of the item to be installed can also be determined, and the horizontal position can be determined by using a spirit level, laser level, or tape measure, with the outer frame of the item to be installed as a reference for horizontal calibration.

[0015] Beneficial effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Precise Positioning: The marking center axis coincides with the hanging center axis, providing a WYSIWYG (what you see is what you get) solution without the need to measure hole positions. The core contribution of this invention is that any concealed hanging positioning device that achieves the coincidence of two center axes can achieve precise positioning without manual measurement.

[0018] 2. Easy to operate: Simply insert the device into the concealed mounting slot, move the item to the wall, and press to complete the positioning mark. There is no need for repeated measurement and adjustment, which greatly improves the installation efficiency.

[0019] 3. High adaptability: The snap-fit ​​connector adopts a replaceable design and can be adapted to different specifications of concealed hanging slots.

[0020] 4. Reusable: The device can be completely removed after marking is completed. After the marking part is replaced or replenished, it can be used again, which is economical and environmentally friendly. Attached Figure Description

[0021] Figure 1 This is a three-dimensional structural diagram of an embodiment of the present invention.

[0022] Figure 2 This is a cross-sectional structural diagram of an embodiment of the present invention.

[0023] Figure 3 This is a schematic diagram of the exploded structure according to an embodiment of the present invention. Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] like Figures 1 to 3As shown in the figure, an embodiment of the present invention provides a concealed positioning device, including a snap-fit ​​component 1, an outer cylinder 2, a telescopic marking component 3, an elastic reset component 4, a support part 5, and an anti-detachment structure 6.

[0026] The snap-fit ​​component 1 is located at the top of the device. Its shape and size match the concealed hanging slot of the item to be installed. It is detachably snapped into the concealed hanging slot, allowing the entire device to be suspended from the back of the item. The snap-fit ​​component 1 has a central hanging shaft. The connection between the snap-fit ​​component 1 and the outer cylinder 2 is replaceable, such as a threaded connection, a snap-fit ​​connection, or an interference fit, so that the appropriate snap-fit ​​component 1 can be replaced according to different concealed hanging slot specifications.

[0027] The outer cylinder 2 is a hollow cylindrical structure, with a telescopic marking assembly 3 inserted inside. The telescopic marking assembly 3 can slide along the axial direction of the outer cylinder 2. The telescopic marking assembly 3 includes a shaft post 31 and a coloring part 32 integrally formed on the front end of the shaft post 31, the diameter of the coloring part 32 being larger than the diameter of the shaft post 31. The front end of the telescopic marking assembly 3, i.e., the front end face of the coloring part 32, is provided with a marking forming part 7. The marking forming part 7 has a marking central axis, which coincides with the hooking central axis of the snap-fit ​​member 1.

[0028] An elastic reset member 4 is disposed between the outer cylinder 2 and the telescopic marking assembly 3. In this embodiment, the elastic reset member 4 is a helical spring, sleeved on the shaft 31, with one end abutting against the inner wall step of the outer cylinder 2 and the other end abutting against the rear end face of the colored part 32. The elastic reset member 4 applies an elastic force to the telescopic marking assembly 3, causing it to retract upwards away from the wall.

[0029] The support part 5 is located on the bottom end face of the outer cylinder 2 and is used to abut against the wall surface when pressed. The support part 5 has anti-slip properties, and its surface can be provided with anti-slip texture or made of anti-slip materials such as rubber to prevent the device from sliding relative to the wall surface when pressed. The support part 5 can be a continuous annular pad, multiple circumferentially distributed columnar supports, multiple protrusions, or multiple block structures.

[0030] The anti-detachment structure 6 is used to prevent the telescopic marking assembly 3 from detaching from the outer cylinder 2. In this embodiment, the anti-detachment structure 6 is a limiting outer cylinder with a three-layer stepped structure: the first layer 61 wraps around the shaft 31 and provides it with sliding guidance; the inner stepped surface of the second layer 62 cooperates with the front end surface of the coloring part 32 to limit the retraction stroke of the telescopic marking assembly 3, and the outer stepped surface cooperates with the rear end surface of the coloring part 32 to limit the downward stroke of the telescopic marking assembly 3; the third layer 63 hides the coloring part 32 and the marking forming part 7 inside when not in operation, thus providing protection.

[0031] The marking forming part 7 is used to leave positioning marks on the wall surface. The marking forming part 7 can be a carrier that can absorb or store pigment, such as a photosensitive pad, sponge, felt, or ink absorber; it can also be a directly writable material such as chalk, wax block, or water-soluble pigment block; or it can be a hard tip, such as a metal tip, used to create indentations on the wall surface. The marking forming part 7 and the coloring part 32 can be connected by a replaceable connection, such as a plug-in, adhesive, or threaded connection, for easy replacement or replenishment.

[0032] In use, first select the appropriate snap-fit ​​component 1 according to the specifications of the concealed hanging slot of the item to be installed, and install it on the outer cylinder 2. Then, snap the snap-fit ​​component 1 into the concealed hanging slot on the back of the item to be installed, so that the device is suspended on the item. Move the item to be installed to the target installation area on the wall, so that the support part 5 abuts against the wall. Use a spirit level or laser level to adjust the item to a horizontal position with the outer frame of the item as a reference. After confirming the position, press the item to be installed towards the wall. At this time, the outer cylinder 2 and the snap-fit ​​component 1 move towards the wall with the item. The telescopic marking component 3 extends towards the wall against the elastic reset component 4, and the marking forming part 7 contacts the wall and leaves a positioning mark on the wall. After releasing the pressing force, the telescopic marking component 3 retracts and resets under the action of the elastic reset component 4, and the marking forming part 7 retracts into the anti-detachment structure 6. Finally, remove the item to be installed from the wall, drill holes or install nails according to the positioning mark left on the wall, and then hang the item.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various improvements and modifications without departing from the spirit and principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
