Description

Technical Field

[0001] The present invention relates to the technical field of downlights, and particularly to a self-limiting anti-pinch lamp. Background Art

[0002] As a common embedded lighting device, a downlight usually adopts a spring fixing structure to achieve rapid connection between the lamp and the installation base. In the prior art, the spring fixing structure on the downlight generally realizes elastic clamping between the lamp and the installation base through a pre-tightening force. Its typical structure includes U-shaped brackets and torsion springs arranged on both sides of the lamp body. The U-shaped brackets are connected to the torsion springs and are driven by the torsion springs to have a pre-tightening force for clamping with the installation base. When installing this type of downlight, it is necessary to push the U-shaped bracket by hand to swing upward against the elastic force of the torsion spring, and then insert the U-shaped bracket and the upper part of the lamp body into the installation hole of the installation base. Then release the U-shaped bracket. The U-shaped bracket swings downward under the action of the torsion spring and is clamped to the inner wall surface of the installation base, thereby fixing the whole lamp to the installation base. After passing the lamp body through the installation hole, the hand needs to release the U-shaped bracket. At this time, the torsion spring will drive the U-shaped bracket to swing downward quickly, and it is easy to pinch the hand. Summary of the Invention

[0012] Technical solution eight based on technical solution one: the sliding rod includes a first rod body and a second rod body which are sleeved on each other and threadedly matched.

[0013] Technical solution nine based on technical solution one: also includes a segmented part, which is slidably fitted with the lamp body along the up and down directions; the damping part includes a first damping body and a second damping body which are independent of each other, the first damping body acts on the lamp body and the segmented part respectively along the up and down directions, and the second damping body acts on the segmented part and the sliding part respectively along the up and down directions.

[0014] Technical solution ten based on technical solution nine: the lamp body is provided with a protruding blocking portion, the blocking portion is located on the sliding path of the sliding part in the up and down directions, and is configured to be suitable for pressing against the sliding part to block the sliding part from sliding upward to disengage from the sliding rod; the lamp body is provided with a limiting portion located below the sliding part, and the limiting portion is configured to be suitable for pressing against the sliding part to make the sliding part stop at the fourth position.

[0015] It can be seen from the above description of the present invention that, compared with the prior art, the present invention has the following beneficial effects:

[0016] Technical solution 1 provides a self-limiting anti-pinch lamp, which mainly includes a lamp body, an elastic clip, a sliding member, a damping member and a spring. The lamp can be installed at the mounting hole position of a substrate, and the lamp is fixed on the substrate by the elastic clip and the lamp body clamping the upper and lower surfaces of the substrate. Among them, the sliding member can slide up and down relative to the lamp body, and the sliding member can abut against the elastic clip upward, so that the elastic clip is kept in the first position, the spring is fixedly connected to the sliding member, and the spring can abut against the lower surface of the substrate to drive the sliding member to move downward, so that the elastic clip can leave the first position and reach the second position.

[0017] Before installing the lamp, first open the elastic clip upward and keep it in the first position, then slide the sliding member up to the third position, and after the sliding member abuts against the elastic clip upward in the third position, the elastic clip can be released. Under the action of the elastic force, the elastic clip tends to swing downward relative to the lamp body, but at this time the sliding member is located below the elastic clip, and the elastic clip applies a downward force on the sliding member that is outward relative to the lamp body, and the force can be divided into two components, a downward force and an outward force. The downward force pushes the sliding member to slide down, and the outward force makes the sliding member close to the lamp body and form a friction force with the lamp body through friction cooperation to hinder the sliding member from sliding downward. At the same time, the damping member applies an upward force to the sliding member, and when the friction force and the force applied by the damping member are added together, they are greater than the downward force component of the elastic clip on the sliding member, or when the friction force is small, as long as the force applied by the damping member is greater than the downward force component of the elastic clip on the sliding member, the sliding member can support the elastic clip to keep the elastic clip in the first position. Afterwards, the lamp with the elastic clip held in the first position can be passed through the mounting hole on the substrate. At this time, there is no need to apply force to the elastic clip, and the installer can hold other parts of the lamp to avoid the position of the elastic clip.

[0018] After the lamp body passes through the installation hole, the lamp body can be pushed up by hand. At this time, the pressing part on the spring sheet will contact the lower surface of the substrate or the edge of the installation hole. The substrate applies a downward force to the pressing part, thereby driving the sliding member to slide downward and leave the third position, and then remove the support of the sliding member on the elastic clip, so that the elastic clip can swing down to abut the upper surface of the substrate. At this time, the installer's hand will not be in a place where the elastic clip can clamp. In addition, the force formed by the elastic clip abutting against the upper surface of the substrate after swinging downward is relatively large, which can easily overcome the force of the damping member or the sum of the force of the damping member and the friction force, so that the lamp body moves up as a whole.

[0019] After that, the sliding member slides downward to the fourth position. When the sliding member is in the fourth position, it will not interfere with the elastic clip, enabling the elastic clip to be in the second position, so that the lamp can be clamped and fixed on the substrate through the mutual cooperation of the elastic clip and the abutting flange on the lamp body. And during this process, the elastic piece will deform due to its own elasticity, so the elastic piece will not hinder the sliding member from sliding to the fourth position. Therefore, by providing the elastic piece, during the installation of the lamp, it only needs to push the lamp body into place to automatically complete the downward sliding of the sliding member and the fixing of the elastic clip, and single-handed operation can be achieved, making the installation of the lamp more convenient and fast. Moreover, the elastic piece will be blocked by the abutting flange of the lamp body and will not be exposed from the lower surface of the substrate, making the lamp more flat and beautiful after installation. In addition, since the elastic piece only needs to apply a downward force to break the balance when the sliding member is in balance, the elastic piece does not need to always abut against the lower surface of the substrate. When the sliding member is in the fourth position, there can be a certain distance between the lower end of the sliding member and the free end of the elastic piece and the abutting flange of the lamp body, so as to avoid the sliding member and the pressing member from interfering with components such as fireproof cotton and buffer silica gel installed on the lamp.

[0020] With the above structure, when installing the lamp, there is no need to continuously apply force to the elastic clip by hand to keep it open, the installation is more convenient, and there is no need to contact the clip during the installation process, reducing the risk of pinching hands.

[0021] In Technical Solution 2, the shape and size of the elastic piece are designed such that when the elastic clip is in the second position, the free end of the elastic piece is located between the lamp body and the hole wall of the mounting hole. At this time, the elastic piece has a tendency to deform outward, but is restricted by the hole wall of the mounting hole. At the same time, the elastic piece will not completely enter above the substrate. Therefore, when removing the lamp, during the downward movement of the lamp, the elastic piece will not interfere with the upper surface of the substrate, and the lamp can be easily removed.

[0022] In Technical Solution 3, the elastic piece is set to be arc-shaped. Compared with the linear structure, the position where the pressing portion of the arc-shaped structure is set can be the same, so a good abutting fit with the substrate can be formed. And the arc-shaped structure can ensure that the elastic piece has sufficient length, so that when the elastic clip is in the second position, its free end can be located between the lamp body and the hole wall of the mounting hole, and at the same time, it will not make the length of the elastic piece extending outward too long. If the length of the elastic piece extending outward is too long, it will cause the lamp to be difficult to package and is easily damaged due to unexpected touch. More importantly, since the elastic piece is arc-shaped, its deformation tendency is different from that of the linear shape. Its free end will not directly abut against the hole wall of the mounting hole with the outermost end, but will abut against the hole wall of the mounting hole with the side surface of the elastic piece, which can increase the contact area and reduce the fatigue of the elastic piece.

[0023] In Technical Solution 4, the elastic clip is composed of an elastic member and an abutting arm. The sliding member gives way outward to form a yielding space, which can ensure that the sliding member will not interfere with the elastic member when sliding up and down, guaranteeing the smooth movement of the sliding member and the elastic clip.

[0024] In Technical Solution 5, the sliding member is provided with a yielding groove, and the abutting arm is provided with a retracted portion with a width adaptation. The cooperation of the yielding groove and the retracted portion enables the elastic clip to swing downward to the second position without the sliding member having to be located too far below, and can ensure that the sliding member will not interfere with the elastic clip at the second position. At the same time, when the elastic clip is bent upward to the first position, due to the change in the relative positions of the elastic clip and the sliding member, the abutting portion of the sliding member will abut against other positions of the elastic clip except the retracted portion. At this time, the sliding member can effectively abut against the elastic clip. Therefore, the structure of the yielding groove, the retracted portion, and the abutting portion can cooperate with each other, enabling the sliding member to perform the abutting function on the elastic clip while avoiding the sliding member from interfering with the elastic clip, and the moving range of the sliding member is appropriate, preventing the sliding member from being too far down and interfering with the substrate.

[0025] In Technical Solution 6, at least two sliding contact portions for slidingly cooperating with the lamp body are provided on the sliding member. The provision of multiple sliding contact portions can make the sliding of the sliding member on the lamp body more stable, reduce the swaying of the sliding member, and generate sufficient friction between the sliding member and the lamp body when subjected to the force of the elastic clip. At the same time, the yielding space is provided between the two sliding contact portions, and the overall structural design of the sliding member is more reasonable, ensuring the structural strength and function realization of the sliding member itself.

[0026] In Technical Solution 7, the lamp body is provided with a sliding rod, and the sliding contact portion of the sliding member is provided with a sliding hole. The sliding rod can extend into the sliding hole and form a clearance fit, enabling the sliding member to slide up and down along the sliding rod; and the damping member is set as a spring, which can be conveniently sleeved on the sliding rod and can avoid bending deformation, making the force exerted by the damping member on the sliding member more stable.

[0027] In Technical Solution 8, the sliding rod includes a first rod body and a second rod body that are sleeved with each other and in threaded cooperation. The first rod body can be set to be relatively fixed, and the second rod body can be set to be relatively rotatable. By rotating the second rod body, the overall length of the sliding rod can be adjusted, thereby adjusting the up and down stroke of the sliding member, facilitating the adaptation to damping members with different damping forces and elastic clips with different elastic forces.

[0028] In Technical Solution 9, a segmented member is provided, and a first damping body and a second damping body are respectively provided above and below the segmented member, so that the damping member can provide segmented damping characteristics: in the initial stage of lamp installation, mainly rely on the first damping body to provide a small damping force to ensure that the lamp body can smoothly pass through the installation hole; in the subsequent installation stage, the first and second damping bodies act together to provide a moderate or large damping force to ensure that the sliding member can reliably lift the elastic clip and maintain stability, and finally achieve a stable self-limiting anti-pinch function. Among them, the magnitude and characteristics of the damping force can be set according to the requirements of different installation stages to achieve the segmented damping effect.

[0029] In Technical Solution 10, a blocking portion is provided on the lamp body to limit the upward sliding stroke of the sliding member and prevent the sliding member from disengaging from the sliding fit with the lamp body. A limiting portion is provided on the lamp body to limit the downward sliding stroke of the sliding member and can accurately limit the position where the sliding member can stop at the fourth position to avoid interference between the sliding member and the elastic clip.

[0050] Embodiment

[0051] An embodiment of the present invention relates to a pinch-proof lamp 20. Referring to Figure 1 , the lamp 20 includes a lamp body 21, an elastic clip 22, a sliding member 30, a damping member 40, and a spring piece 50.

[0052] The lamp 20 is adapted to be installed on a substrate 10 provided with a mounting hole 11. Specifically, reference can be made to Figure 4 and Figure 5 , which respectively show the mating relationship between the lamp 20 and the substrate 10 in two different states. Generally speaking, the lamp 20 can be a downlight, and the substrate 10 is generally a ceiling. Therefore, the upper and lower sides of the substrate 10 respectively form the upper surface of the substrate 10 and the lower surface of the substrate 10. At the same time, a mounting hole 11 can be formed on the substrate 10, and the lamp 20 can be fixedly installed at the position of the mounting hole 11 through the cooperation of the lamp body 21 and the elastic clip 22.

[0053] Among them, the lamp body 21 included in the lamp 20 is generally cylindrical. Of course, in other embodiments, the shape of the lamp body 21 can be adjusted according to actual needs. For example, it can be set as a cuboid shape or other shapes. Generally speaking, the lamp body 21 is generally in a shape with an extension structure in the up and down directions. Its bottom is set as a light outlet, and a light-emitting device, a controller, a driver, etc. are arranged inside it. Generally, a heat dissipation device is arranged on its top, and wires can extend outwards from the top to be connected to an external power supply device. Refer to Figure 1, a butt-joint flange 23 extending outward is provided at the bottom of the lamp body 21. As used in this specification and the claims, "extending outward" is relative to the spatial position occupied by the lamp body 21. The direction toward the inside of the lamp body 21 is inward, and the direction away from the lamp body 21 and toward the outside is outward. The size of the butt-joint flange 23 is larger than the size of the mounting hole 11 on the substrate 10, which enables the butt-joint flange 23 to completely cover the mounting hole 11 and be in butt-joint cooperation with the lower surface of the substrate 10 outside the mounting hole 11. In this embodiment, a flexible foam component, such as EVA foam, can be provided on the butt-joint flange 23 to avoid damaging the lower surface of the substrate 10 when the lamp 20 is fixed to the substrate 10. In this embodiment, the outer edge of the butt-joint flange 23 extends upward to form an upper flange edge 231, and the upper flange edge 231 can enclose to form a groove structure, which is convenient for setting the flexible foam component and can make the appearance more concise.

[0054] In this embodiment, referring to Figure 1 , the lamp body 21 includes a main body, a sliding rod 24, and a fixing base 26. The fixing base 26 is fixedly installed on the main body by bolts, and the sliding rod 24 is threadedly fixed to the fixing base 26, which will be described in detail below. In addition, in this specification and the claims, the "inner and outer directions" can be regarded as the radial direction of the cylindrical lamp body 21, and the direction toward the lamp body 21 is inward, and the direction away from the lamp body 21 is outward.

[0055] The number of the elastic clips 22 included in the lamp 20 is at least two, and they can rotate relative to the lamp body 21. In this embodiment, the number of the elastic clips 22 is set to two, and the two elastic clips 22 are symmetrically arranged at an interval of 180°. Among them, referring to Figure 1, the elastic clip 22 includes an elastic member 221 and an abutting arm 222. The elastic member 221 is installed on the lamp body 21, and the abutting arm 222 is integrally formed with or has a connection relationship with the elastic member 221. The relative rotation of the elastic clip 22 with respect to the lamp body 21 mainly means that the abutting arm 222 can rotate relative to the lamp body 21. The elastic member 221 basically only deforms rather than changes its position relative to the lamp body 21. Therefore, on the basis that the elastic member 221 is installed on the lamp body 21, the abutting arm 222 can be directly rotatably connected to the lamp body 21 through structures such as a rotating shaft, or the relative rotation with the lamp body 21 can be indirectly realized through the cooperation between the elastic member 221 and the lamp body 21. Specifically, the elastic member 221 can be set as a torsion spring. The torsion spring is installed on the lamp body 21 through a shaft rod formed on the lamp body 21 as a whole, and one end of the torsion spring is fixed on the lamp body 21, and the other end thereof is connected to the abutting arm 222. In a general design, the torsion spring is generally made of metal, and the abutting arm 222 is also made of metal. Therefore, the torsion spring and the abutting arm 222 can be integrally formed. Or, in other installation methods, a box-shaped extension part can be directly led out from the torsion spring, and the extension part can be inserted and fixed into a corresponding slot in the lamp body 21. Under the limiting action of the slot, the elastic member 221 can be fixedly installed on the lamp body 21, and at the same time, by using the elastic force of the elastic member 221 itself, the abutting arm 222 can also rotate relative to the lamp body 21. Refer to Figure 1 , the elastic member 221 is arranged at a position close to the lamp body 21, and the abutting arm 222 extends outward relative to the lamp body 21. A buffer sleeve can be arranged at the free end of the abutting arm 222, and the buffer sleeve can be made of materials such as plastic and rubber to increase the contact area between the free end of the abutting arm 222 and the upper surface of the substrate 10. In this embodiment, the position of the fixing seat 26 on the lamp body 21 corresponds to the position of the elastic clip 22, and the elastic member 221 of the elastic clip 22 is fixedly installed in the slot on the fixing seat 26.

[0056] Among them, the elastic clip 22 can move between a first position and a second position. Refer to Figure 2 and Figure 4 , in the first position, the elastic clip 22 extends upward and is in an open state. Refer to Figure 3 and Figure 5, when in the second position, the elastic clip 22 swings downward to a state of extending obliquely downward toward the outside. And, when the elastic clip 22 is in the first position, the elastic clip 22 opens upward so that the size of the lamp 20 in the horizontal direction is smaller than the size of the mounting hole 11. Therefore, the lamp 20 can pass through the mounting hole 11 and the elastic clip 22 enters the space above the substrate 10. When the elastic clip 22 is in the second position, the elastic clip 22 swings downward under the elastic action of the elastic member 221, and the abutting arm 222 presses downward against the upper surface of the substrate 10. At the same time, the reaction force of the upper surface of the substrate 10 on the elastic clip 22 will cause the entire lamp body 21 to move upward until the abutting flange 23 abuts upward against the lower surface of the substrate 10. At this time, with the cooperation of the elastic clip 22 and the abutting flange 23, the lamp 20 can be fixed on the substrate 10. It should be understood that Figure 4 and Figure 5 The figures shown are only schematic diagrams and do not represent the state in the actual application scenario. For the convenience of explaining the installation process of the easily installable lamp 20 involved in the embodiments of the present invention, some of its structures are simplified and adjusted. The dimensional relationship and positional relationship between the mounting hole 11 and the elastic clip 22 should be subject to the written description in the specification. The drawings are only for auxiliary explanation.

[0057] Referring to Figure 1 , the sliding member 30 in the lamp 20 is slidably engaged with the lamp body 21 in the up and down direction and moves between a third position on the upper side and a fourth position on the lower side; in the third position, the sliding member 30 abuts upward against the elastic clip 22 in the first position and receives the force applied by the elastic clip 22 to maintain the third position through the frictional engagement between it and the lamp body 21; in the fourth position, the elastic clip 22 is allowed to be in the second position. And, the damping member 40 acts on the lamp body 21 and the sliding member 30 in the up and down direction respectively and is adapted to apply an upward force to the sliding member 30; in the third position, the sliding member 30 abuts upward against the elastic clip 22 in the first position and uses the force of the damping member 40 on it to overcome the force of the elastic clip 22 on it to maintain the third position; in the fourth position, the elastic clip 22 is allowed to be in the second position.

[0058] Among them, at least two sliding members 30 are provided corresponding to the elastic clips 22 one by one. In this embodiment, two elastic clips 22 are provided, so two sliding members 30 are correspondingly provided. This kind of setting scheme has a simple overall structure, can ensure that each elastic clip 22 can be limited by the sliding member 30, the holding effect of the sliding member 30 on the elastic clip 22 is better, and it is convenient for the installation of the sliding member 30, reducing the overall production cost of the lamp 20. Of course, in other embodiments, an annular sliding member 30 surrounding the outside of the lamp body 21 can be provided, which can also play a role in limiting the elastic clip 22.

[0059] Reference Figure 2 and Figure 3 , the sliding member 30 is slidably arranged on the lamp body 21 and can move between the third position in Figure 2 and the fourth position in Figure 3 . In this embodiment, the sliding member 30 is provided with at least two sliding contact portions 34 arranged along the circumferential direction of the lamp body 21 and used for sliding cooperation with the lamp body 21; the lamp body 21 is provided with a sliding rod 24 extending in the up and down direction; the sliding contact portion 34 on the sliding member 30 is provided with a sliding hole 341 penetrating up and down, and the sliding hole 341 is in clearance fit with the sliding rod 24.

[0060] Specifically, the fixing base 26 is provided with two assembly holes 261, the inner wall of the assembly hole 261 is provided with internal threads, the bottom of the sliding rod 24 is provided with external threads, and the sliding rod 24 can be fixed to the fixing base 26 by means of threaded connection, and then assembled to the main body of the lamp body 21. The sliding rod 24 is generally in the shape of a rod extending upward and can cooperate with the sliding contact portion 34 on the sliding member 30 to enable the sliding member 30 to slide up and down relative to the lamp body 21. Among them, corresponding to one sliding member 30, the lamp body 21 is provided with two sliding rods 24, and the sliding member 30 is also provided with two sliding contact portions 34 corresponding to the two sliding rods 24. Reference Figure 1 , these two sliding contact portions 34 can be regarded as ear-shaped structures extending from the main body of the sliding member 30 along the circumferential direction to both sides. The sliding holes 341 penetrating up and down are provided on the two sliding contact portions 34, and the outer diameter of the sliding rod 24 matches the inner diameter of the sliding hole 341, so that the sliding hole 341 can form a clearance fit with the sliding rod 24.

[0061] The part between the two sliding contact portions 34 of the sliding member 30 is the main body of the sliding member 30. The upper end of this main body forms a top holding portion 31. The top holding portion 31 can abut against the elastic clip 22 during the process of the sliding member 30 sliding upward away from the fourth position, or the elastic clip 22 can be first bent upward to the first position, and then the sliding member 30 is slid upward to the third position, and the top holding portion 31 of the sliding member 30 abuts against the abutting arm 222 of the elastic clip 22. At this time, due to the specific positional relationship, the frictional force between the sliding member 30 and the sliding rod 24 is just balanced with the elastic force of the elastic member 221 on the abutting arm 222, so that the elastic clip 22 is kept in the first position, and at the same time the sliding member 30 is kept in the third position. The sliding member 30 is provided with at least two sliding contact portions 34 for sliding cooperation with the lamp body 21. The arrangement of multiple sliding contact portions 34 can make the sliding of the sliding member 30 on the lamp body 21 more stable and reduce the shaking of the sliding member 30.

[0062] In this embodiment, the damping member 40 is a spring, which is sleeved on the above-mentioned sliding rod 24, and the lower end of the damping member 40 abuts against the fixed seat 26, and the upper end of the damping member 40 abuts against the sliding portion 34 of the sliding member 30, so as to apply an upward force to the sliding member 30. When the sliding member 30 reaches the third position, the upward force applied by the damping member 40 to the sliding member 30 will cause the sliding member 30 to overcome the acting force of the elastic clip 22 on it and remain in the third position. When the sliding member 30 reaches the fourth position, although the force applied by the damping member 40 to the sliding member 30 is greater at this time, but at this time the downward acting force of the elastic clip 22 on the sliding member 30 is greater than the acting force of the damping member 40 on the sliding member 30, so the sliding member 30 will remain in the fourth position.

[0063] Further, in this embodiment, the sliding rod 24 includes a first rod body and a second rod body that are sleeved with each other and in threaded cooperation. Specifically, an internal thread is provided at the bottom of the first rod body, and the first rod body is directly screwed and fixed on the fixed seat 26. At the same time, an internal thread or an external thread is formed on the upper side portion of the first rod body, and a corresponding external thread or internal thread is formed on the lower side portion of the second rod body. The second rod body can be screwed on the first rod body, and by rotating the second rod body, the height position of the second rod body relative to the first rod body can be adjusted, so as to adjust the overall length of the sliding rod 24, and further adjust the up and down stroke of the sliding member 30, which is convenient for adapting to elastic clips 22 with different elastic forces.

[0064] Moreover, in this embodiment, a segmenting member is further provided, which is slidably engaged with the lamp body 21 in the up and down direction; the damping member 40 includes independent first and second damping bodies. The first damping body acts on the lamp body 21 and the segmenting member in the up and down direction respectively, and the second damping body acts on the segmenting member and the sliding member 30 in the up and down direction respectively. Specifically, the segmenting member is an annular member with a through hole in the middle, so that the segmenting member can be sleeved on the sliding rod 24. The damping member 40 is formed by the cooperation of the first and second damping bodies. In this embodiment, two springs sleeved on the sliding rod 24 can be provided. The spring located below is the first damping body, its lower end abuts against the fixed seat 26, and its upper end abuts against the segmenting member; the spring located above is the second damping body, its lower end abuts against the segmenting member, and its upper end abuts against the sliding portion 34. Through the above structure, the damping member 40 can provide segmented damping characteristics: in the initial stage of installing the lamp 20, mainly rely on the first damping body to provide a small damping to ensure that the lamp body 21 can smoothly pass through the installation hole 11 lightly; in the subsequent installation stage, the first and second damping bodies act together to provide a moderate or large damping force to ensure that the sliding member 30 can reliably lift the elastic clip 22 and maintain stability, and finally achieve a stable self-limiting anti-pinch function. Among them, different damping force magnitudes and characteristics can be set according to the requirements of different installation stages to achieve the segmented damping effect.

[0065] Meanwhile, referring to Figure 1 , at least at the part corresponding to the elastic clip 22, the sliding member 30 gives way outward relative to the lamp body 21 to form a yielding space 33 that does not interfere with the elastic member 221. The yielding space 33 is formed between the two sliding connection parts 34. It is easy to understand that the outward yielding of the sliding member 30 here means that the main body part of the sliding member 30 is more outward relative to its two sliding connection parts 34. The two sliding connection parts 34 are formed by slanting and extending from the main body of the sliding member 30 towards the lamp body 21, thereby forming a yielding space 33 between the sliding member 30 and the sliding 24 of the lamp body 21. The yielding space 33 can ensure that the sliding member 30 will not interfere with the elastic member 221 when sliding up and down, ensuring the smooth movement of the sliding member 30 and the elastic clip 22.

[0066] In addition, referring to Figure 1 , the sliding member 30 is provided with a yielding groove 32 that is recessed downward and penetrates in the inner and outer directions corresponding to the abutting arm 222. The abutting arm 222 is provided with a retracted portion 223 adapted to the width of the yielding groove 32 corresponding to the yielding groove 32; in the first position, a top holding portion 31 that abuts the abutting arm 222 upward is formed at the top of the sliding member 30; in the second position, the retracted portion 223 of the abutting arm 222 is located in the yielding groove 32.

[0067] Specifically, a yielding groove 32 is provided on the main body part of the sliding member 30. The yielding groove 32 is recessed downward from the top of the main body part of the sliding member 30 and penetrates in the inner and outer directions, having a certain width and depth. At the same time, corresponding to the yielding groove 32, a retracted portion 223 is provided on the abutting arm 222 of the elastic clip 22. The size of the retracted portion 223 is adapted to the width of the yielding groove 32, and its length position on the abutting arm 222 is just when Figure 3 the sliding member 30 shown is in the fourth position, the retracted portion 223 can enter the yielding groove 32. It is easy to understand that the abutting arm 222 usually has a width direction corresponding to its length direction. In this width direction, the abutting arm 222 has a certain width. Generally, the width of the abutting arm 222 is consistent in its length direction. In this embodiment, a section of the abutting arm 222 is particularly set as a width-reducing section, that is, the above-mentioned retracted section. Referring to Figure 3When the sliding member 30 is at the fourth position, the retracted section of the abutting arm 222 just falls into the clearance groove 32, and when the sliding member 30 is at the third position, the supporting portion 31 will normally abut against the normal width portion of the abutting arm 222. The cooperation between the clearance groove 32 and the retracted portion 223 ensures that when the elastic clip 22 swings downward to the second position, the position of the sliding member 30 does not need to be too far below, and it can be ensured that the sliding member 30 will not interfere with the elastic clip 22 at the second position. At the same time, when the elastic clip 22 is bent upward to the first position, due to the change in the relative position of the elastic clip 22 and the sliding member 30, the supporting portion 31 of the sliding member 30 will abut against other positions of the elastic clip 22 except the retracted portion 223, and at this time, the sliding member 30 can effectively support the elastic clip 22. Therefore, the structures of the yield groove 32, the retracted portion 223 and the supporting portion 31 are provided, and the three can cooperate with each other, so that the sliding member 30 can play the supporting function of the elastic clip 22, and the sliding member 30 can be prevented from interfering with the elastic clip 22, and the moving range of the sliding member 30 is appropriate to prevent the sliding member 30 from being too low and interfering with the substrate 10.

[0068] Further, refer to Figure 1 The lamp body 21 is provided with a blocking portion 241 protruding therefrom. The blocking portion 241 is located on the sliding path of the sliding member 30 in the up-down direction and is configured to be suitable for resisting the sliding member 30 to prevent the sliding member 30 from sliding upward to be separated from the sliding rod 24. The lamp body 21 is provided with a limiting portion 25 located below the sliding member 30. The limiting portion 25 is configured to be suitable for resisting the sliding member 30 to make the sliding member 30 stop at the fourth position.

[0069] Specifically, the blocking portion 241 is disposed at the top of the sliding rod 24, and it is a flange structure that extends uniformly outward relative to the axis of the sliding rod 24, so that the size of the top of the sliding rod 24 is larger than the outer diameter of its lower position. After the slider 30 slides upward beyond the third position, the sliding joint portion 34 will be limited by the blocking portion 241 and cannot continue to slide upward, thereby restricting the upward sliding stroke of the slider 30 and preventing the slider 30 from disengaging from the sliding fit with the lamp body 21. Among them, since the sliding rod 24 is installed by fixedly connecting its lower end to the body of the lamp body 21, during assembly, the slider 30 can be first sleeved on the sliding rod 24, and then the sliding rod 24 can be screwed and fixed to the body of the lamp body 21. The limiting portion 25 is a table structure provided on the fixed seat 26 corresponding to the position of the sliding rod 24 in this embodiment. The height of this table structure is preset. When the slider 30 slides downward to the fourth position, the sliding joint portion 34 of the slider 30 will abut against this table structure, so that the slider 30 stops at the fourth position and cannot continue to slide downward. Through this limiting portion 25, the downward sliding stroke of the slider 30 can be restricted, and the slider 30 can be accurately limited to be able to stop at the fourth position, avoiding interference between the slider 30 and the elastic clip 22.

[0070] Further, referring to Figure 1 , the elastic piece 50 is fixedly connected to the slider 30 and extends outward relative to the lamp body 21, and it is provided with a pressing portion 51; the pressing portion 51 is adapted to abut upward against the lower surface of the substrate 10 to provide a force for the slider 30 to move downward against the friction force, and make the elastic piece 50 pass through elastic deformation so that its free end crosses the lower side hole edge of the mounting hole 11. Among them, the elastic piece 50 is configured such that when the elastic clip 22 is in the second position, its free end is located between the lamp body 21 and the hole wall of the mounting hole 11.

[0071] Specifically, referring to Figure 1 and Figure 2 , the elastic piece 50 can be a metal or plastic thin sheet, which has a certain structural strength and good elasticity. After it is installed on the slider 30, the elastic piece 50 as a whole extends outward relative to the lamp body 21, and this outward extension can be set to extend outward and downward. The upper end of the elastic piece 50 is its fixed end. After the upper side portion of the elastic piece 50 is bent downward to form a bent structure, the bent structure can be lapped on the bottom of the relief groove 32 of the slider 30, and then the fixed end of the elastic piece 50 can be fixed on the slider 30 by screws. Connecting in this way can effectively improve the connection firmness between the elastic piece 50 and the slider 30. Referring to Figure 4, a pressing portion 51 is provided at the middle position of the elastic piece 50. When the sliding member 30 is in the third position, the position of the pressing portion 51 of the elastic piece 50 in space is exactly such that during the process of the lamp 20 passing through the mounting hole 11 on the substrate 10, it contacts the edge of the mounting hole 11. Then, the elastic piece 50 will be deformed by the force exerted on it by the edge of the mounting hole 11, and at the same time, the downward force received will pull the sliding member 30 to move downward against the friction force, thereby releasing the elastic clip 22 in the first position. And, during this process, due to the elastic deformation of the elastic piece 50 itself, during the process of its contact with and being stressed by the edge of the mounting hole 11, the elastic piece 50 will not interfere with the mounting hole 11, and finally the free end of the elastic piece 50 will cross the lower edge of the mounting hole 11. Further, after the lamp 20 is installed in place, that is, when the elastic clip 22 is in the second position, the free end of the elastic piece 50 will be located between the lamp body 21 and the hole wall of the mounting hole 11, that is, the hole wall of the mounting hole 11 limits the elastic piece 50. At this time, the elastic piece 50 has a tendency to deform outward, but is restricted by the hole wall of the mounting hole 11, and at the same time, the elastic piece 50 will not completely enter above the substrate 10. Therefore, when the lamp 20 is removed, during the downward movement of the lamp 20, the elastic piece 50 will not interfere with the upper surface of the substrate 10, and the lamp 20 can be easily removed.

[0072] In addition, referring to Figure 1 , Figure 2 and Figure 4 , the elastic piece 50 starts from its connection position with the sliding member 30 and is in an arc shape bent toward the position where the lamp body 21 is located. Compared with a straight-line structure, the position where the pressing portion 51 is provided can be the same, so a good abutting fit can be formed with the substrate 10. And, the arc-shaped structure can ensure that the elastic piece 50 has sufficient length, so that when the elastic clip 22 is in the second position, its free end can be located between the lamp body 21 and the hole wall of the mounting hole 11, and at the same time, it will not make the length of the elastic piece 50 extending outward too long. If the length of the elastic piece 50 extending outward is too long, it will cause the lamp 20 to be difficult to package and is easily damaged due to unexpected touches. More importantly, since the elastic piece 50 is arc-shaped, its deformation tendency is different from that of a straight-line shape. Its free end will not directly abut against the hole wall of the mounting hole 11 with its outermost end, but will abut against the hole wall of the mounting hole 11 with the side surface of the elastic piece 50, which can increase the contact area and reduce the fatigue of the elastic piece 50.

[0073] The present embodiment relates to a self-limiting anti-pinch lamp 20, which mainly includes a lamp body 21, an elastic clip 22, a sliding member 30, a damping member 40 and a spring 50. The lamp 20 can be installed at the mounting hole 11 of the substrate 10, and the lamp 20 is fixed on the substrate 10 by clamping the upper and lower surfaces of the substrate 10 by the elastic clip 22 and the lamp body 21. The sliding member 30 can slide up and down relative to the lamp body 21, and the sliding member 30 can abut against the elastic clip 22 upward, so that the elastic clip 22 is kept in the first position, and the spring 50 is fixedly connected to the sliding member 30, and the spring 50 can abut against the lower surface of the substrate 10 to drive the sliding member 30 to move downward, so that the elastic clip 22 can leave the first position and reach the second position.

[0074] Before installing the lamp 20, the elastic clip 22 is first opened upward and kept in the first position, and then the sliding member 30 is slid up to the third position. After the sliding member 30 abuts against the elastic clip 22 upward at the third position, the elastic clip 22 can be released. Under the action of the elastic force, the elastic clip 22 tends to swing downward relative to the lamp body 21, but at this time the sliding member 30 is located below the elastic clip 22. The elastic clip 22 exerts a downward force on the sliding member 30 and an outward force relative to the lamp body 21. The force can be divided into two components, a downward force and an outward force. The downward force pushes the sliding member 30. 0 slides down, the outward force will make the sliding member 30 close to the lamp body 21 and form a friction force that hinders the sliding member 30 from sliding downward through friction cooperation with the lamp body 21. At the same time, the damping member 40 will apply an upward force to the sliding member 30. When the friction force and the force applied by the damping member 40 add up to be greater than the downward force of the elastic clip 22 on the sliding member 30, or when the friction force is small, as long as the force applied by the damping member 40 is greater than the downward force of the elastic clip 22 on the sliding member 30, the sliding member 30 can support the elastic clip 22 and keep the elastic clip 22 in the first position. Afterwards, the lamp 20 with the elastic clip 22 in the first position can be passed through the mounting hole 11 on the substrate 10. At this time, there is no need to apply force to the elastic clip 22. The installer can hold other parts of the lamp 20 to avoid the position of the elastic clip 22.

[0075] After the lamp body 21 passes through the mounting hole 11, the lamp body 21 can be continuously pushed upward by hand. At this time, the pressing portion 51 on the elastic piece 50 will contact the lower surface of the substrate 10 or the edge of the mounting hole 11, and the substrate 10 applies a downward force to the pressing portion 51, thereby driving the sliding member 30 to slide downward and leave the third position, and then removing the abutment of the sliding member 30 against the elastic clip 22, so that the elastic clip 22 can swing downward to abut against the upper surface of the substrate 10. At this time, the installer's hand will not be in the place where the elastic clip 22 can clamp. Moreover, the acting force formed after the elastic clip 22 swings downward and abuts against the upper surface of the substrate 10 is relatively large, and it can easily overcome the acting force of the damping member 40 or the sum of the acting force and the frictional force of the damping member 40, so that the whole lamp body 21 moves upward.

[0076] After that, the sliding member 30 slides downward to the fourth position. When the sliding member 30 is in the fourth position, it will not interfere with the elastic clip 22, so that the elastic clip 22 can be located at the second position, so that the lamp 20 can be clamped and fixed on the substrate 10 through the mutual cooperation of the elastic clip 22 and the abutting flange 23 on the lamp body 21. And in this process, the elastic piece 50 will deform due to its own elasticity, so the elastic piece 50 will not hinder the sliding member 30 from sliding to the fourth position. Therefore, by setting the elastic piece 50, during the installation of the lamp 20, only the lamp body 21 needs to be pushed in place to automatically complete the downward sliding of the sliding member 30 and the fixing of the elastic clip 22, which can realize single-handed operation, and the installation of the lamp 20 is more convenient and fast. Moreover, the elastic piece 50 will be blocked by the abutting flange 23 of the lamp body 21 and will not be exposed from the lower surface of the substrate 10, making the lamp 20 more flat and beautiful after installation. In addition, since the elastic piece 50 only needs to apply a downward force to break the balance when the sliding member 30 is in balance, the elastic piece 50 does not need to always abut against the lower surface of the substrate 10. When the sliding member 30 is in the fourth position, the lower end of the sliding member 30 and the free end of the elastic piece 50 can be at a certain distance from the abutting flange 23 of the lamp body 21, so as to avoid the sliding member 30 and the pressing member from interfering with components such as fireproof cotton and buffer silica gel installed on the lamp 20.

[0077] With the above structure, when installing the lamp 20, there is no need to continuously apply force to the elastic clip 22 by hand to keep it open, the installation is more convenient, and there is no need to contact the clip during the installation process, reducing the risk of pinching hands.

[0078] The above description of the specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the inspiration of the present invention or the above embodiments, those of ordinary skill in the art, combined with common general knowledge, ordinary technical knowledge in the art and / or the prior art, through logical analysis, reasoning or limited experiments, can obtain modifications, equivalent replacements or other improvements to the embodiments of the present invention or some of its technical features, which should all be included in the protection scope of the present invention.
