Description

Technical Field

[0001] This utility model relates to the field of lighting equipment, and in particular to a manually adjustable damping sliding component, an adjusting component, and a lamp. Background Technology

[0002] Sliding components are commonly used in many fields due to their flexible adjustability, especially in manually adjustable products, such as lighting fixtures.

[0003] Common sliding components include undamped and damped versions. Undamped sliding components are generally used in conjunction with actuators; while damped sliding components are mostly used in products that require manual adjustment.

[0004] Damped sliding components have built-in damping between the slider and the track. Therefore, manual adjustment requires overcoming resistance to push the slider, and it automatically stops at the desired position. The advantage of this type of sliding component is its ease of adjustment. However, its disadvantages are: since the damping resistance is pre-set at the factory, the damping magnitude cannot be adjusted, making it unsuitable for different user adjustment forces. Secondly, because the damping is pre-set at the factory and decreases over time, in some applications requiring rotational adjustment, the torque generated by rotation can cause the damping between the slider and the track to fail.

[0005] Currently, there is no sliding component on the market that can automatically adjust the sliding damping.

[0006] Therefore, there is an urgent need for a manually adjustable sliding component, adjustment component, and lighting fixture with adjustable damping and convenient adjustment method to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a manually adjustable sliding component with adjustable damping and convenient adjustment method.

[0008] To achieve the above objectives, the present invention provides a manually adjustable damping sliding assembly comprising a track, at least one slider, and a damping adjustment device. The slider is slidably disposed on the track. The damping adjustment device comprises a connecting plate, a movable block, a manual adjustment component, and an elastic component. The movable block is slidably disposed on the track and connected to the slider via the connecting plate. The movable block is located between the track and the connecting plate. The elastic component is disposed inside the movable block. The manual adjustment component is threadedly connected to the connecting plate and passes through the connecting plate to press against the elastic component. The elastic component presses against the movable block. The manual adjustment component can be rotated relative to the connecting plate to change the pressure on the elastic component, thereby changing the pressure on the movable block, thus changing the friction between the movable block and the track, and thus changing the sliding damping of the sliding assembly.

[0009] Preferably, when the manual adjustment component is tightened in the forward direction, it rotates towards the track, applying pressure to the elastic element. This pressure, in turn, applies pressure to the movable block, increasing the friction between the movable block and the track, and thus increasing the sliding damping of the sliding assembly. When the manual adjustment component is loosened in the reverse direction, it retracts away from the track, releasing pressure from the elastic element. This pressure release, in turn, releases pressure from the movable block, reducing the friction between the movable block and the track, and thus reducing the sliding damping of the sliding assembly.

[0010] Preferably, the movable block is made of POM material.

[0011] Preferably, the elastic element is a plurality of elastic pads stacked on top of each other, and all the elastic pads are stacked in opposite pairs.

[0012] Preferably, the movable block is provided with a receiving cavity for accommodating the elastic element, and the bottom of the movable block is provided with a through hole for a manual adjustment element to pass through. The diameter of the through hole is smaller than the diameter of the receiving cavity, and the through hole is connected to the receiving cavity.

[0013] Preferably, the manual adjustment component includes a head and a stud portion connected in sequence, the head protruding from the connecting plate, the stud portion passing through the connecting plate, and the stud portion having a pressing surface for pressing against the elastic element.

[0014] Preferably, a connecting post protrudes from the bottom surface of the stud portion, and a sleeve hole matching the connecting post is provided in the middle of the elastic element. The connecting post passes through the sleeve hole, and the diameter of the connecting post is smaller than the diameter of the stud portion, so that the connecting post and the shoulder of the stud portion form the pressing surface.

[0015] Preferably, the connecting plate is provided with a connecting hole for threaded connection with the manual adjustment component, and the connecting plate is also provided with a mounting hole for connection with the slider.

[0016] Another objective of this invention is to provide an adjustment component with adjustable damping and a convenient adjustment method.

[0017] To achieve the above objectives, the adjustment component of this utility model includes two sets of the aforementioned manually adjustable damping sliding components. The two sets of manually adjustable damping sliding components are symmetrically arranged about an R-axis and can rotate relative to each other about the R-axis.

[0018] Another objective of this invention is to provide a lamp with adjustable damping and a convenient adjustment method.

[0019] To achieve the above objectives, the lamp of this utility model includes a lamp holder, a light source, and the aforementioned adjustment component, wherein the adjustment component is disposed on the lamp holder and the light source is disposed on the adjustment component; or the lamp of this utility model includes a lamp holder, a light source, and the aforementioned manually adjustable damping sliding component, wherein the manually adjustable damping sliding component is disposed on the lamp holder and the light source is disposed on the manually adjustable damping sliding component.

[0020] Compared with existing technologies, the manually adjustable damping sliding assembly of this invention utilizes a damping adjustment device. When the manual adjustment piece is turned forward and tightened, it rotates closer to the track, applying pressure to the elastic element. This pressure, in turn, applies pressure to the movable block, increasing the friction between the movable block and the track surface, thus increasing the sliding damping of the sliding assembly. Conversely, when the manual adjustment piece is turned backward and loosened, it retracts away from the track, releasing pressure on the elastic element. This pressure release, in turn, releases pressure on the movable block, reducing the friction between the movable block and the track surface, thus reducing the sliding damping of the assembly. Therefore, the manually adjustable damping sliding assembly of this invention has the advantage of easily adjustable sliding damping. Furthermore, because the pressure of the elastic element on the movable block is elastic, the resulting damping is not abrupt, resulting in a better feel when the slider is adjusted relative to the track. Similarly, the adjustment component of this utility model has two sets of the aforementioned manually adjustable damping sliding components, thus also having the advantage of easily adjustable sliding damping; similarly, the lamp of this utility model has the aforementioned adjustment component or the aforementioned manually adjustable damping sliding component, thus also having the advantage of easily adjustable sliding damping during the adjustment of the light source position.

[0029] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] Please see Figures 1 to 2 The illustration shows a lamp 100 of this utility model, which includes a lamp holder 1, a light source 5, and an adjustment component 3. The adjustment component 3 is disposed on the lamp holder 1, and the light source 5 is disposed on the adjustment component 3. With the help of the adjustment component 3, the position of the light source 5 can be manually adjusted, making the light source 5 adjustable in multiple directions, such as vertically, horizontally, or diagonally.

[0031] Specifically, please refer to Figures 3 to 5 The present invention demonstrates the adjustment component 3, which includes two sets of manually adjustable damping sliding components. For ease of description, one of the manually adjustable damping sliding components will be referred to as the first manually adjustable damping sliding component 31, and the other set will be referred to as the second manually adjustable damping sliding component 32. It is understood that the structures of the two sets of manually adjustable damping sliding components are identical. Specifically, the first manually adjustable damping sliding component 31 is mounted on the lamp holder 1, and the light source 5 is mounted on the second manually adjustable damping sliding component 32, and the light source 5 can rotate relative to the second manually adjustable damping sliding component 32. Specifically, the first manually adjustable damping sliding component 31 and the second manually adjustable damping sliding component 32 are symmetrically arranged around an R-axis and can rotate relative to each other. Specifically, both the first manually adjustable damping sliding component 31 and the second manually adjustable damping sliding component 32 have a damping shaft 7 passing through them, and the damping shaft 7 is located on the R-axis. Specifically, the damping shaft 7 includes two rotatable ends. One end of the damping shaft 7 can rotate relative to the other end as long as it is subjected to a force resisting damping. The damping shaft 7 is a commercially available part, and its structure and principle are well known to those skilled in the art, so they will not be described in detail here.

[0032] Therefore, with the help of the adjustment component 3, the height of the light source 5 can be adjusted when the first slider 311 (mentioned below) in the first manually adjustable damping first sliding component 31 slides along the first track 312 (mentioned below); when the second manually adjustable damping second sliding component 32 is rotated and the second track 322 (mentioned below) slides relative to the second slider 321 (mentioned below), the light source 5 can be adjusted to face any area of ​​use.

[0033] It is understood that the multi-directional adjustable adjustment component 3 of this utility model can be applied not only to the lamp 100, but also to other electronic products or furniture, etc., and is not limited thereto.

[0034] Please see Figures 6 to 8 The first sliding component 31 and the second sliding component 32 with manually adjustable damping of this utility model are shown.

[0035] Please see Figures 6 to 7 The manually adjustable damping first sliding assembly 31 includes a first track 312, at least one first slider 311, and a first damping adjustment device 315. For example, in this embodiment, there are two first sliders 311; however, in other embodiments, there may be one, three, four, or five first sliders 311, and this is not a limitation. Specifically, the two first sliders 311 are spaced apart and slide simultaneously on the first track 312. By using multiple first sliders 311, the force-bearing area between the first sliders 311 and the first track 312 is increased, thus reducing the pressure and making the sliding of the first manually adjustable damping sliding assembly 31 more stable and reliable. Specifically, the first track 312 is mounted on the lamp holder 1. The first track 312 is arranged along the Y-axis direction, but this is not a limitation.

[0036] The first damping adjustment device 315 includes a first connecting plate 3154, a first movable block 3151, a first manual adjustment member 3152, and a first elastic member 3153. The first movable block 3151 is slidably disposed on the first track 312 and connected to the first slider 311 through the first connecting plate 3154. The first movable block 3151 is located between the first track 312 and the first connecting plate 3154. The first elastic member 3153 is provided inside the first movable block 3151. The first manual adjustment member 3152 is threadedly connected to the first connecting plate 3154 and passes through the first connecting plate 3154 to press against the first elastic member 3153. The first elastic member 3153 presses against the first movable block 3151. The first manual adjustment member 3152 rotates relative to the first connecting plate 3154 to change the pressure on the first elastic member 3153, thereby changing the pressure on the first movable block 3151, thus changing the friction between the first movable block 3151 and the first track 312, thereby changing the sliding damping of the first sliding assembly 31.

[0037] Specifically, when the first manual adjustment member 3152 is tightened in the forward direction, it rotates towards the first track 312. At this time, the first manual adjustment member 3152 applies pressure to the first elastic member 3153, which in turn applies pressure to the first movable block 3151, thereby increasing the friction between the contact surface of the first movable block 3151 and the first track 312, and thus increasing the sliding damping of the first sliding assembly 31. When the first manual adjustment member 3152 is loosened in the reverse direction, it retracts away from the first track 312. At this time, the first manual adjustment member 3152 releases pressure on the first elastic member 3153, which in turn releases pressure on the first movable block 3151, thereby reducing the friction between the contact surface of the first movable block 3151 and the first track 312, and thus reducing the sliding damping of the first sliding assembly 31.

[0038] Preferably, the first movable block 3151 is made of POM material, thus possessing high strength, high rigidity, high wear resistance, self-lubrication, and excellent insulation. Therefore, the first movable block 3151 can repeatedly slide on the first track 312.

[0039] Preferably, the first elastic element 3153 is a plurality of first elastic pads stacked on top of each other. Of course, in other embodiments, the first elastic element 3153 may be a spring or a spring post, and is not limited thereto. More specifically, the first elastic pad is a butterfly-shaped pad, and the plurality of first elastic pads are stacked in opposite pairs to obtain a larger deformation space. When the elastic pad is compressed, it can obtain a larger elastic potential energy, thereby generating a greater resistance force on the first movable block 3151.

[0040] Preferably, the bottom of the first movable block 3151 is provided with a first through hole 31512 for the manual adjustment component to pass through, and the first through hole 31512 is connected to the first receiving cavity 31511. The first through hole 31512 allows for no limitation on the threaded tightening stroke of the manual adjustment component. When the threaded surface is long enough, it can be tightened until the bottom surface of the first manual adjustment component 3152 abuts against the surface of the first track 312.

[0041] Specifically, the first manual adjustment member 3152 includes a first head 31521 and a first stud portion (not shown) connected in sequence. The first head 31521 protrudes from the first connecting plate 3154, and the first stud portion passes through the first connecting plate 3154. The first stud portion has a pressing surface (not shown) for pressing against the first elastic member 3153. It is understood that the first connecting plate 3154 has a first connecting hole 31544 for threaded connection with the first stud portion. Preferably, the first connecting plate 3154 has a first recessed hole 31545 recessed at the first connecting hole 31544 for positioning the head 31521. The first recessed hole 31545 also extends upward through the upper end face of the first connecting plate 3154, so that the first head 31521 is partially exposed in the first recessed hole 31545 in its radial direction and also partially exposed in the first recessed hole 31545 in its axial direction. Preferably, the bottom surface of the first stud portion 31522 has a connecting post (not shown in the figure) protruding from it, and the middle of the first elastic member 3153 has a sleeve hole 31531 that matches the first connecting post. The first connecting post passes through the sleeve hole 31531, and the diameter of the connecting post is smaller than the diameter of the stud portion, so that a pressing surface is formed at the shoulder of the connecting post and the stud portion. With the cooperation between the first connecting post and the sleeve hole 31531, when the first elastic member 3153 is compressed and moves, it can move concentrically, so that the generated pressing force is also in the same direction, preventing the pressing force from being dispersed. Preferably, the surface of the first head 31521 is roughened, which increases the friction when a person touches the first head 31521 for adjustment, thus facilitating tightening.

[0042] Please see Figure 8 The manually adjustable damping second sliding assembly 32 includes a second track 322, at least one second slider 321, and a second damping adjustment device 326. For example, in this embodiment, there are two second sliders 321; however, in other embodiments, there may be one, three, four, or five second sliders 321, and this is not a limitation. Specifically, the two second sliders 321 are spaced apart and slide simultaneously on the second track 322. By using multiple second sliders 321, the force-bearing area between the second sliders 321 and the second track 322 is increased, thus reducing the pressure and making the sliding of the manually adjustable damping second sliding assembly 32 more stable and reliable. Specifically, the light source 55 is mounted at the end of the second track 322 and is rotatable.

[0043] Specifically, please refer to Figure 8The second damping adjustment device 326 includes a second connecting plate 3264, a second movable block 3261, a second manual adjustment member 3262, and a second elastic member 3263. The second movable block 3261 is slidably disposed on the second track 322 and connected to the second slider 321 through the second connecting plate 3264. The second movable block 3261 is located between the second track 322 and the second connecting plate 3264. The second elastic member 3263 is provided inside the second movable block 3261. The second manual adjustment member 3262 is threadedly connected to the second connecting plate 3264 and passes through the second connecting plate 3264 to press against the second elastic member 3263. The second elastic member 3263 presses against the second movable block 3261. The second manual adjustment member 3262 rotates relative to the second connecting plate 3264 to change the pressure on the second elastic member 3263, thereby changing the pressure on the second movable block 3261, thus changing the friction between the second movable block 3261 and the second track 322, thereby changing the sliding damping of the second sliding assembly 32.

[0044] Specifically, when the second manual adjustment member 3262 is turned on the right, it rotates towards the second track 322. At this time, the second manual adjustment member 3262 applies pressure to the second elastic member 3263, which in turn applies pressure to the second movable block 3261, thereby increasing the friction between the contact surface of the second movable block 3261 and the second track 322, and thus increasing the sliding damping of the second sliding assembly 32. When the second manual adjustment member 3262 is turned on the left, it retracts away from the second track 322. At this time, the second manual adjustment member 3262 releases pressure on the second elastic member 3263, which in turn releases pressure on the second movable block 3261, thereby reducing the friction between the contact surface of the second movable block 3261 and the second track 322, and thus reducing the sliding damping of the second sliding assembly 32.

[0045] Please see Figure 8 Preferably, the second movable block 3261 is made of POM material, thus possessing high strength, high rigidity, high wear resistance, self-lubrication, and excellent insulation. Therefore, the second movable block 3261 can repeatedly slide on the second track 322; Please see Figure 8 Preferably, the second elastic element 3263 is a plurality of overlapping second elastic pads. Of course, in other embodiments, the second elastic element 3263 may be a spring or a spring column, and is not limited thereto. More specifically, the second elastic pad is a butterfly-shaped pad, and the plurality of second elastic pads are stacked in opposite pairs to obtain a larger deformation space. When the second elastic pad is compressed, it can obtain a larger elastic potential energy, thereby generating a greater resistance force on the second movable block 3261.

[0046] Please see Figure 8 The bottom of the second movable block 3261 is provided with a second through hole (not shown in the figure) for the manual adjustment component to pass through, and the second through hole is connected to the second receiving cavity. The second through hole allows for unrestricted thread tightening stroke of the second manual adjustment component 3262. When the thread surface is long enough, it can be tightened until the bottom surface of the second manual adjustment component 3262 abuts against the surface of the second track 322.

[0047] Please see Figure 8 Specifically, the second manual adjustment member 3262 includes a second head 32621 and a second stud portion 32622 connected in sequence. The second head 32621 protrudes from the second connecting plate 3264, and the second stud portion 32622 passes through the second connecting plate 3264. The second stud portion 32622 is provided with a pressing surface 32624 for pressing against the second elastic member 3263. It is understood that the second connecting plate 3264 is provided with a second connecting hole 32644 for threaded connection with the stud portion 32622. Preferably, the second connecting plate 3264 has a second recessed hole (not shown in the figure) recessed at the second connecting hole 32644 for positioning the head 32621. The second recessed hole also penetrates downward through the lower end face of the second connecting plate 3264, so that the second head 32621 is partially exposed in the second recessed hole in its radial direction and also partially exposed in the second recessed hole in its axial direction. Preferably, a second connecting post 32623 protrudes from the bottom surface of the second stud portion 32622, and a sleeve hole 32631 matching the second connecting post 32623 is provided in the middle of the second elastic member 3263. The second connecting post 32623 passes through the sleeve hole 32631, and the diameter of the second connecting post 32623 is smaller than the diameter of the second stud portion 32622, so that a pressing surface 32624 is formed at the shoulder of the second connecting post 32623 and the second stud portion 32622. With the cooperation between the second connecting post 32623 and the sleeve hole 32631, when the second elastic member 3263 is compressed and moves, it can move concentrically, so that the generated pressing force is also in the same direction, preventing the pressing force from being dispersed. Preferably, the side of the second head 32621 is a friction surface, which increases the friction when a person touches the second head 32621 for adjustment, thereby facilitating tightening.

[0048] Please see Figure 5Specifically, a damping shaft 7 is simultaneously inserted through the middle of the first connecting plate 3154 and the second connecting plate 3264, and the damping shaft 7 is located on the R-axis. The damping shaft 7 includes two ends that can rotate relative to each other. One end of the damping shaft 7 is inserted through the first connecting plate 3154, and the other end of the damping shaft 7 is inserted through the second connecting plate 3264. It can be understood that, with the help of the damping shaft 7, after the second manually adjustable damping sliding component 32 rotates relative to the first manually adjustable damping sliding component 31 and stops rotating, the second manually adjustable damping sliding component 32 can still maintain its rotated position.

[0049] Please see Figures 6 to 7 To facilitate the assembly of the first connecting plate 3154, the first slider 311, and the damping shaft 7, a first mounting hole 31541 for the damping shaft 7 to pass through the middle of the first connecting plate 3154 is provided, and several second mounting holes 31542 for threaded fasteners to pass through the upper and lower parts of the first connecting plate 3154. It is understood that the first slider 311 and the first connecting plate 3154 are fixedly connected by threaded fasteners. Preferably, in order to prevent the head 31521 of the threaded fastener from protruding from the surface of the first connecting plate 3154, the surface of the first connecting plate 3154 is also recessed at the second mounting hole 31542, so that the head of the threaded fastener is hidden in the first slot 31543, making the gap between the first manually adjustable damping sliding component 31 and the second manually adjustable damping sliding component 32 smaller, and the two will not interfere with each other when the first manually adjustable damping sliding component 31 and the second manually adjustable damping sliding component 32 pivot relative to each other.

[0050] Please see Figure 8 Similarly, to facilitate the assembly of the second connecting plate 3264, the second slider 321311, and the damping shaft 7, the second connecting plate 3264 has a third mounting hole 32641 through its middle for the damping shaft 7 to pass through, and several fourth mounting holes 32642 through its upper and lower parts for threaded fasteners to pass through. It is understood that the second slider 321 and the second connecting plate 3264 are fixedly connected by threaded fasteners. Preferably, in order to prevent the head 31521 of the threaded fastener from protruding from the surface of the second connecting plate 3264, the surface of the second connecting plate 3264 is also recessed at the fourth mounting hole 32642, so that the head of the threaded fastener is hidden in the second slot 32643, making the gap between the first manually adjustable damping sliding component 31 and the second manually adjustable damping sliding component 32 smaller, and the first manually adjustable damping sliding component 31 and the second manually adjustable damping sliding component 32 will not interfere with each other when they pivot relative to each other.

[0051] Compared with existing technologies, the manually adjustable damping sliding assembly of this invention utilizes a damping adjustment device. When the manual adjustment component is turned forward and tightened, it rotates closer to the track, applying pressure to the elastic component. This pressure, in turn, applies pressure to the movable block, increasing the friction between the movable block and the track surface, thus increasing the sliding damping of the sliding assembly. Conversely, when the manual adjustment component is turned backward and loosened, it retracts away from the track, releasing pressure on the elastic component. This pressure release, in turn, releases pressure on the movable block, reducing the friction between the movable block and the track surface, and thus reducing the sliding damping of the sliding assembly. Therefore, the manually adjustable damping sliding assembly of this invention has the advantage of easily adjustable sliding damping. Furthermore, because the pressure of the elastic component on the movable block is elastic, the resulting damping is not abrupt, resulting in a better feel when the slider is adjusted relative to the track. Similarly, the adjustment component of this utility model has two sets of the aforementioned manually adjustable damping sliding components, thus also having the advantage of easily adjustable sliding damping; similarly, the lamp of this utility model has the aforementioned adjustment component or the aforementioned manually adjustable damping sliding component, thus also having the advantage of easily adjustable sliding damping during the adjustment of the light source position.

[0052] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
