Description

Technical Field

[0001] The present invention relates to the technical field of lamp installation, in particular to a self-adaptive positioning auxiliary mechanism for lamp installation. Background Art

[0002] When installing lamps such as downlights and spotlights, you must first lay out the lamps at the ceiling installation location, obtain the hole origin, and then drill holes at the hole origin in the ceiling to facilitate the installation of downlights and spotlights.

[0003] Currently, drilling is typically done with a hole saw during construction. However, due to a lack of effective positioning assistance, the hole saw can easily deviate from the drilling origin, causing the drilled hole to deviate from the pre-defined origin. Inaccurate hole positioning not only affects the proper installation of the luminaire, but also necessitates re-drilling, resulting in wasted materials and reduced construction efficiency. Summary of the Invention

[0004] The present invention provides a self-adaptive positioning auxiliary mechanism for lamp installation, which can overcome certain defects of the prior art.

[0005] According to the present invention, an adaptively adjustable positioning auxiliary mechanism for lamp installation includes a mechanism body, which includes a mounting rod, a positioning member that cooperates with the opening origin at the end of one end of the mounting rod, and the positioning member has at least three mounting planes arranged parallel to the ceiling, and the orientations of the three mounting planes correspond to any three directions of the front, rear, left, and right in space. The three mounting planes are each provided with a measuring instrument, which is used to cooperate with the corresponding wall surface to achieve re-measurement of the positioning size of the opening origin;

[0006] A support assembly is telescopically provided at the mounting rod, and the support assembly is used to support and position the mounting rod to achieve verticality between the positioning piece and the corresponding ceiling at the opening origin.

[0007] The present invention discloses an adaptively adjustable positioning auxiliary mechanism for lamp installation, which is provided with at least three installation planes parallel to the ceiling and facing any three directions of the front, rear, left and right in different directions in space through the positioning piece. A measuring instrument is installed at each installation plane. During the lamp installation process, the measuring instrument can cooperate with the corresponding wall surface, and compare the data such as the distance from the positioning piece to the wall surface with the relevant dimensions of the opening origin positioned in advance, thereby realizing the re-measurement of the opening origin positioning dimension. In this way, possible deviations in the opening origin positioning can be discovered in time, and the problem of inaccurate drilling position in the subsequent drilling is avoided, which not only reduces the waste of materials, but also saves construction time and improves construction efficiency.

[0008] It can be understood that the provision of the support assembly enables the measuring instrument to be in a vertical position relative to the ceiling, thereby improving measurement accuracy.

[0009] Preferably, the support assembly includes a fixed ring arranged at the mounting rod and a first movable ring slidably arranged at the mounting rod, the first movable ring is hinged with a plurality of abutment arms along the circumference, the fixed ring is hinged with a second support arm corresponding to the plurality of abutment arms along the circumference, and the second support arm is hinged to the abutment arm at one end away from the fixed ring.

[0010] Multiple abutment arms are distributed circumferentially along the first movable ring and connected to the fixed ring via second support arms, forming a stable support structure. When the abutment arms abut against the ceiling, they provide stable support for the mounting rod, ensuring that the positioning member is perpendicular to the corresponding ceiling at the hole origin, thereby ensuring the accuracy of the hole origin positioning.

[0011] It can be understood that when support is needed, support can be achieved by pushing the first movable ring, and when use is completed, the first movable ring can be pulled back to collect, which is easy to collect and simple and convenient to operate.

[0012] Preferably, a locking assembly is provided at the first movable ring, and the locking assembly includes a tightening part provided at the first movable ring, the tightening part has a plurality of connecting plates equidistantly arranged along the circumference of the first movable ring, and the connecting plates are formed with external threads near the outer wall of the first movable ring, and a fastening tube is rotatably provided at the tightening part, and an internal thread that cooperates with the external thread is formed inside the fastening tube, and the fastening tube is used to cooperate with the tightening part to limit the first movable ring.

[0013] After the supporting assembly adjusts the telescopic length by sliding the first movable ring so that the abutting arm reaches a suitable supporting state, the function of the locking assembly is to fix the position of the first movable ring. The multiple connecting pieces of the tightening part are equidistantly arranged along the circumference of the first movable ring, and the connecting piece has an external thread near the outer wall of the first movable ring, which cooperates with the internal thread inside the fastening tube. When the fastening tube is rotated, due to the threaded fit, the fastening tube will move along the connecting piece and exert pressure on the tightening part, causing the tightening part to hold the first movable ring tightly, thereby locking the first movable ring in a specific position on the mounting rod, which helps the measuring instrument to more accurately remeasure the hole origin positioning dimensions, reduce the measurement error caused by unstable support, thereby improving the accuracy of hole origin positioning, and provide a more accurate position reference for subsequent drilling and lamp installation.

[0014] Specifically, the locking assembly operates by rotating the fastening tube, which locks the first movable ring through threaded engagement. This operation is relatively simple, requiring no complex skills or tools. Furthermore, to adjust the extension length of the support assembly, simply rotate the fastening tube in the opposite direction to unlock it, adjust the position of the first movable ring, and relock it. This is quick and convenient, improving construction efficiency.

[0015] Preferably, a driving assembly is provided at the mounting rod, and a positioning member is provided at the output end of the driving assembly. The positioning member includes a mounting seat provided at the output end of the driving assembly, a positioning needle is provided at the mounting seat and is coaxially arranged with the mounting rod, and extension rods are symmetrically provided at the side walls on both sides of the mounting seat, and a scratching knife is provided at the extension rod; wherein the length of the scratching knife is less than the length of the positioning needle.

[0016] Through the coordinated arrangement of the scoring knife, the driving assembly and the positioning pin, when the driving assembly is working, the scoring knife can use the positioning pin as the center of the circle to make a hole in the ceiling. After re-measurement, the hole opening operation can be performed without the need to use a hole opener for the hole opening operation, thereby improving work efficiency.

[0017] It can be understood that the length of the scratching knife is smaller than the length of the positioning pin, so that when the user is drilling a hole, he or she can release the limit of the support component by the locking component, push the installation rod to make the positioning pin insert into the ceiling first, and then continue to push the installation rod to perform the hole drilling operation.

[0018] Preferably, the extension rod is formed with a mounting groove along the length direction, and a through hole is formed at the top wall of the mounting groove. A cutter is slidably provided in the mounting groove, and a bolt is provided at the through hole for limiting the cutter.

[0019] The mounting groove on the extension rod provides a sliding space for the cutter, so that the cutter can be adjusted along the length of the extension rod to adapt to the opening requirements of different apertures, thereby adapting to the installation requirements of various different specifications of lamps.

[0020] Preferably, a clamping seat corresponding to the abutting arm is formed on the outer wall of the mounting seat, and a groove is formed on the clamping seat, and the groove is used to cooperate with the abutting arm to achieve circumferential limitation of the mounting seat.

[0021] Through the cooperation between the card seat and the abutment arm, when the abutment arm is in the storage state, Figure 6 In the state shown, the abutment arm forms a circumferential limit on the mounting seat, so that the mounting seat will not rotate during positioning re-measurement, thereby improving measurement accuracy.

[0022] Preferably, an anti-sliding block is provided at the end of the abutting arm away from one end of the first movable ring.

[0023] Through the above-mentioned mechanism, when the abutment arm abuts against the ceiling or the surrounding supporting surface, the friction force generated between the anti-sliding block and the supporting surface will be significantly increased, which can effectively prevent the abutment arm from sliding or displacing during the support process, ensuring that the support assembly can provide stable support for the installation rod, and thereby ensuring that the positioning piece remains vertical to the corresponding ceiling at the origin of the opening.

[0024] It is understandable that the anti-sliding block can also play a role of buffering and protection, avoiding direct hard contact between the abutting arm and the ceiling, and reducing scratches, wear or damage to the ceiling.

[0025] Preferably, a collecting assembly is provided at the mounting rod, and the collecting assembly includes a second movable ring slidably provided at the mounting rod, the second movable ring is provided between adjacent abutting arms, the second movable ring is hinged with multiple connecting arms along the circumference, oilcloth is provided between the multiple inner walls, a second support arm is hinged at the end of the connecting arm away from one end of the second movable ring, the second support arm is hinged to the fixed ring at the end away from one end of the connecting arm, and the second support arm is provided between adjacent first support arms.

[0026] By setting the collection component, the collection component is in the following position when re-measuring the hole origin positioning size. Figure 6 The stored state shown in FIG. 1 is convenient for the user to align the positioning needle with the hole origin. When performing the punching operation, the connecting arm and the oilcloth at the connecting arm are stretched open by pushing the second movable ring. Figure 1 、 Figure 2 and Figure 3 The state shown is convenient for collecting the broken materials produced when the hole is opened.

[0027] Preferably, a recess for the abutment arm to engage is formed on the outer wall corresponding to the second movable ring and the abutment arm.

[0028] Through the above structure, when the storage assembly and the support assembly are stored, the abutment arm and the storage assembly can be stored to the position as shown in FIG. Figure 6 In the state shown, the volume is small and there is no need to climb up to open the hole, which improves the practicality of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] In order to further understand the content of the present invention, the present invention is described in detail with reference to the embodiments. It should be understood that the embodiments are merely for explanation of the present invention and are not intended to limit the present invention.

[0037] Example 1

[0038] See also Figure 1-6 This embodiment provides an adaptively adjustable positioning auxiliary mechanism for lamp installation, which includes a mechanism body 100, which includes a mounting rod 110. A positioning member 120 is provided at one end of the mounting rod 110, which cooperates with the origin of the opening. The positioning member 120 has at least three mounting planes arranged parallel to the ceiling. The orientations of the three mounting planes correspond to any three directions of the front, rear, left, and right in space. A measuring instrument 130 is provided on each of the three mounting planes. The measuring instrument 130 is used to cooperate with the corresponding wall surface to achieve re-measurement of the positioning size of the opening origin.

[0039] A support assembly 140 is telescopically provided at the mounting rod 110 , and the support assembly 140 is used to support and position the mounting rod 110 so as to achieve verticality between the positioning member 120 and the corresponding ceiling at the opening origin.

[0040] The present invention discloses an adaptively adjustable positioning auxiliary mechanism for lamp installation, which is provided with at least three installation planes parallel to the ceiling and facing any three directions of the front, rear, left and right in different directions in space through the positioning member 120. A measuring instrument 130 is installed at each installation plane. During the lamp installation process, the measuring instrument 130 can cooperate with the corresponding wall surface, and compare the data such as the distance from the positioning member 120 to the wall surface with the relevant dimensions of the opening origin positioned in advance, thereby realizing the re-measurement of the opening origin positioning dimension. In this way, possible deviations in the opening origin positioning can be discovered in time, and the problem of inaccurate subsequent drilling positions can be avoided, which not only reduces material waste, but also saves construction time and improves construction efficiency.

[0041] It is understandable that the provision of the support assembly 140 enables the measuring instrument 130 to be in a vertical position relative to the ceiling, thereby improving measurement accuracy.

[0042] In this embodiment, the support assembly 140 includes a fixed ring 310 provided at the mounting rod 110 and a first movable ring 320 slidably provided at the mounting rod 110, the first movable ring 320 is hinged with a plurality of abutment arms 330 along the circumference, the fixed ring 310 is hinged with a second support arm 370 corresponding to the plurality of abutment arms 330 along the circumference, and the second support arm 370 is hinged to the abutment arm 330 at one end away from the fixed ring 310.

[0043] A plurality of abutment arms 330 are distributed circumferentially along the first movable ring 320 and connected to the fixed ring 310 via second support arms 370, forming a stable support structure. When abutment arms 330 abut against the ceiling, they provide stable support for the mounting rod 110, ensuring that the positioning member 120 is perpendicular to the ceiling at the opening origin, thereby ensuring the accuracy of the opening origin location.

[0044] It is understandable that when support is needed, support can be achieved by pushing the first movable ring 320, and when use is completed, collection can be achieved by pulling back the first movable ring 320, which is convenient for collection and easy to operate.

[0045] In this embodiment, a locking assembly 150 is provided at the first movable ring 320, and the locking assembly 150 includes a tightening portion provided at the first movable ring 320, and the tightening portion has a plurality of connecting pieces 410 equidistantly arranged along the circumference of the first movable ring 320, and the connecting pieces 410 are formed with external threads 420 near the outer wall of the first movable ring 320, and a fastening tube 430 is rotatably provided at the tightening portion, and an internal thread that cooperates with the external thread 420 is formed inside the fastening tube 430, and the fastening tube 430 is used to cooperate with the tightening portion to limit the first movable ring 320.

[0046] After the supporting assembly 140 adjusts the telescopic length by sliding the first movable ring 320 so that the abutting arm 330 reaches a suitable supporting state, the function of the locking assembly 150 is to fix the position of the first movable ring 320. The multiple connecting pieces 410 of the tightening part are arranged equidistantly along the circumference of the first movable ring 320, and the connecting piece 410 has an external thread 420 near the outer wall of the first movable ring 320, which cooperates with the internal thread inside the fastening tube 430. When the fastening tube 430 is rotated, due to the threaded fit, the fastening tube 430 will move along the connecting piece 410 and apply pressure to the tightening part, so that the tightening part hugs the first movable ring 320, thereby locking the first movable ring 320 in a specific position on the mounting rod 110, which helps the measuring instrument 130 to more accurately re-measure the hole origin positioning size, reduce the measurement error caused by unstable support, thereby improving the accuracy of the hole origin positioning, and providing a more accurate position reference for subsequent drilling and lamp installation.

[0047] Specifically, the locking assembly 150 primarily operates by rotating the fastening tube 430, which locks the first movable ring 320 through threaded engagement. This operation is relatively simple, requiring no complex skills or tools. Furthermore, to adjust the telescopic length of the support assembly 140, simply reverse the rotation of the fastening tube 430 to unlock it, adjust the position of the first movable ring 320, and then relock it. This is quick and convenient, improving construction efficiency.

[0048] Example 2

[0049] Seen in Figure 1-6 This embodiment also provides an adaptively adjustable positioning auxiliary mechanism for lamp installation, which differs from Example 1 in that: a driving component 510 is provided at the mounting rod 110, and a positioning member 120 is provided at the output end of the driving component 510. The positioning member 120 includes a mounting seat 520 provided at the output end of the driving component 510, and a positioning pin 530 is provided at the mounting seat 520 coaxially with the mounting rod 110. Extension rods 210 are symmetrically provided at the side walls on both sides of the mounting seat 520, and a scratching knife 550 is provided at the extension rod 210; wherein, the length of the scratching knife 550 is less than the length of the positioning pin 530.

[0050] The driving assembly 510 includes a housing, a motor is disposed inside the housing, and the positioning member 120 is disposed at the output end of the motor.

[0051] The mounting rod 110 has an inner cavity formed therein, in which a cylindrical battery is arranged.

[0052] Through the coordinated arrangement of the scoring knife 550, the driving assembly 510 and the positioning pin 530, when the driving assembly 510 is working, the scoring knife 550 can use the positioning pin 530 as the center of the circle to make a hole in the ceiling. After re-testing, the hole opening operation can be performed without the need to use a hole opener for the hole opening operation, thereby improving work efficiency.

[0053] It can be understood that the length of the scratching knife 550 is smaller than the length of the positioning pin 530, so that when the user is drilling a hole, he or she can release the limit of the support component 140 by the locking component 150, push the installation rod 110 to allow the positioning pin 530 to be inserted into the ceiling first, and then continue to push the installation rod 110 to perform the hole drilling operation.

[0054] In this embodiment, the extension rod 210 is formed with an installation groove 540 along the length direction, and a through opening is formed at the top wall of the installation groove 540. A cutter 550 is slidably provided in the installation groove 540, and a bolt 560 is provided at the through opening. The bolt 560 is used to limit the cutter 550.

[0055] The mounting slot 540 on the extension rod 210 provides a sliding space for the cutter 550, so that the cutter 550 can be adjusted along the length of the extension rod 210, so as to adapt to the opening requirements of different apertures, thereby adapting to the installation requirements of various different specifications of lamps.

[0056] In this embodiment, a clamping seat 521 corresponding to the abutting arm 330 is formed on the outer wall of the mounting seat 520 , and a groove is formed on the clamping seat 521 , which is used to cooperate with the abutting arm 330 to achieve circumferential limitation of the mounting seat 520 .

[0057] Through the cooperation between the card seat 521 and the abutting arm 330, when the abutting arm 330 is in the storage state, Figure 6 In the state shown, the abutment arm 330 forms a circumferential limit on the mounting seat 520, so that the mounting seat 520 will not rotate when the positioning remeasurement is performed, thereby improving the measurement accuracy.

[0058] In this embodiment, an anti-sliding block 331 is provided at the end of the abutting arm 330 away from the first movable ring 320 .

[0059] Through the above-mentioned mechanism, when the abutment arm 330 abuts against the ceiling or the surrounding supporting surface, the friction force generated between the anti-sliding block 331 and the supporting surface will be significantly increased, which can effectively prevent the abutment arm 330 from sliding or displacing during the support process, ensuring that the support assembly 140 can stably support the mounting rod 110, and thereby ensuring that the positioning member 120 remains perpendicular to the corresponding ceiling at the origin of the opening.

[0060] It is understandable that the anti-sliding block 331 can also play a role of buffering and protection, avoiding direct hard contact between the abutting arm 330 and the ceiling, and reducing scratches, wear or damage to the ceiling.

[0061] In this embodiment, a collecting assembly 220 is provided at the mounting rod 110, and the collecting assembly 220 includes a second movable ring 350 slidably provided at the mounting rod 110, the second movable ring 350 is provided between adjacent abutting arms 330, the second movable ring 350 is hinged with multiple connecting arms 360 along the circumference, and oilcloth 380 is provided between the multiple inner walls, and a second support arm 370 is hinged at the end of the connecting arm 360 away from one end of the second movable ring 350, the second support arm 370 is hinged to the fixed ring 310 at the end of the second support arm 370 away from one end of the connecting arm 360, and the second support arm 370 is provided between adjacent first support arms 340.

[0062] By setting the collecting component 220, when re-measuring the size of the opening origin, the collecting component 220 is in the following position: Figure 6 The stored state shown in FIG. 1 is convenient for the user to align the positioning pin 530 with the hole origin. When performing the punching operation, the connecting arm 360 and the oil cloth 380 at the connecting arm 360 are stretched open by pushing the second movable ring 350. Figure 1 、 Figure 2 and 3 The state shown is convenient for collecting the broken materials produced when the hole is opened.

[0063] In this embodiment, a recess 351 for the abutting arm 330 to engage is formed on the outer wall of the second movable ring 350 and the outer wall of the abutting arm 330 .

[0064] Through the above structure, when the storage assembly 220 and the support assembly 140 are stored, the abutment arm 330 and the storage assembly 220 can be stored to the position as shown in FIG. Figure 6 In the state shown, the volume is small and there is no need to climb up to open the hole, which improves the practicality of the present disclosure.

[0065] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application based on one or several embodiments provided in the present application to obtain other embodiments, and these embodiments do not exceed the scope of protection of the present application.

[0066] The above is a schematic description of the present invention and its embodiments, which is not restrictive. The embodiments shown in the embodiments are only part of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by the above and, without departing from the purpose of the present invention, designs a structure and embodiment similar to the technical solution without creatively designing, they shall fall within the scope of protection of the present invention.
