Abstract
Description
Technical Field
[0001] The present application relates to a lamp, and particularly to a lamp with a detachable lens. Background Art
[0002] A lamp lens is an optical element that changes the propagation mode and angle of light, converting the parallel light emitted by the lamp into diffused light, thereby achieving the diffusion and focusing effects of the light. Therefore, the quality of the lens directly affects the lighting effect of the lamp.
[0003] Currently, lamp lenses on the market are generally fixed to the lamp body in the following two ways:
[0004] 1. Bolting method: The lamp lens is fixed to the lamp body by screws. When disassembling and assembling, tools are required to complete the disassembly and assembly, which is cumbersome, troublesome, and has low disassembly and assembly efficiency.
[0005] 2. Pressing method: The lamp body is provided with a pressing frame and a locking buckle. The pressing frame is pivotally connected to the lamp body so that the pressing frame can be flipped relative to the lamp body. The lamp lens is installed on the lamp body and is pressed by the pressing frame against the lamp body. The locking buckle and the pressing frame are latched to fix the pressing frame to the lamp body. When using this connection method, the middle part of the lens is prone to deformation, affecting the optical performance of the lamp lens. In order to prevent the lamp lens from deforming, the prior art generally adds reinforcing ribs to the lens and thickens the pressing frame, increasing the manufacturing cost and still being difficult to ensure that the lamp lens does not deform. Summary of the Invention
[0006] Embodiments of the present application provide a lamp with a detachable lens to solve the problems existing in the related art. The technical solutions are as follows:
[0007] Embodiments of the present application provide a lamp with a detachable lens, including:
[0008] A lamp body, on which an installation part is provided, and an installation groove is provided in the middle of the installation part;

The pressing frame is arranged around the installation part, and the pressing frame and the upper edge of the lens are in close contact to press the lens against the lamp body;
[0012] A buckle structure, which is arranged between the lamp body and the pressing frame. When the pressing frame and the upper edge of the lens are in close contact, the buckle structure fixes the lamp body and the pressing frame; and
[0013] A push - type locking structure is provided in the installation groove. The push - type locking structure has a locked state in which it engages with the connecting member and an unlocked state in which it releases the connecting member. The push - type locking structure can be pressed to switch between the locked state and the unlocked state.
[0014] In one embodiment, when the push - type locking structure is in the locked state, the bottom of the lens is in close contact with the lamp board.
[0015] In one embodiment, a first positioning structure is further provided on the lens, and a second positioning structure is provided on the lamp board. The second positioning structure cooperates with the first positioning structure.
[0016] In one embodiment, the number of both the first positioning structure and the second positioning structure is two. The two first positioning structures are disposed at the diagonal positions of the lens, and each second positioning structure cooperates with a corresponding one of the first positioning structures.
[0017] In one embodiment, among the first positioning structure and the second positioning structure, one is a positioning post and the other is a positioning hole.
[0018] In one embodiment, the push - type locking structure includes:
[0019] A mounting base provided with a positioning groove;
[0020] A locking member movably inserted into the positioning groove. The locking member has a locking portion. The locking portion has a retracted state in which it is received in the positioning groove and an extended state in which it extends out of the positioning groove. When the locking portion is in the retracted state, it engages with the connecting member, and when the locking portion is in the extended state, it releases the connecting member; and
[0021] An elastic member located between the locking member and the bottom wall of the positioning groove. The elastic member connects the locking member and the mounting base, and the elastic member is used to provide elastic force to the locking member when the locking portion switches from the retracted state to the extended state.
[0022] In one embodiment, the locking portion has a receiving area for receiving the end of the connecting member. The top opening of the receiving area is reduced when the locking portion is in the retracted state to clamp the end of the connecting member, and the top opening of the receiving area is enlarged when the locking portion is in the extended state to release the end of the connecting member.
[0023] In one embodiment, the locking portion has at least two locking arms, and the at least two locking arms are arranged at intervals and surround the accommodating area.
[0024] In one embodiment, a first limiting portion is provided on the end of the connecting member, and a second limiting portion is provided on the locking arm, and the second limiting portion and the first limiting portion abut against each other to limit the end of the connecting member from leaving the accommodating area.
[0025] In one embodiment, the mounting seat is provided with a first positioning portion, and the locking arm is provided with a second positioning portion, and the second positioning portion cooperates with the first positioning portion when the locking portion is in a retracted state to limit the locking portion from extending out of the positioning slot.
[0026] In one embodiment, the buckle structure includes a buckle and a buckle portion, the buckle portion is arranged on the pressure frame, one end of the buckle is pivoted on the lamp body so that the buckle can be turned upside down relative to the lamp body, and the other end of the buckle is buckled with the buckle portion.
[0027] The advantages or beneficial effects of the above technical solution at least include:
[0028] The lamp of the present invention has a connecting piece in the middle of the lens and a push-type lock structure on the lamp body. When installing, the edge of the lens can be pressed by the pressing frame, so that the edge of the lens and the part near the edge can be closely attached to the lamp board. At the same time, the middle of the lens can be tightened by buckling the connecting piece and the push-type lock structure, so that the middle of the lens and the part near the middle can be closely attached to the lamp board or tend to be attached to the lamp board, thereby eliminating the deformation of the lens or reducing the amount of the lens, effectively preventing the deformation of the lens, and making the lens have better optical performance, thereby improving the lighting effect of the lamp;
[0029] In addition, the edge of the lens is pressed against the light board by a pressing frame and a buckle structure, and the middle of the lens is tightened against the light board by a connecting piece and a push-type lock structure. Both are detachable. When installing, place the lens on the light board and press the lens to engage the connecting piece and the push-type lock structure, then flip down the pressing frame and buckle the buckle structure to complete the installation. When disassembling, unlock the buckle structure, then open the pressing frame, and finally press the lens to disengage the connecting piece and the push-type lock structure. The operation is simple, the disassembly and assembly are convenient, and the disassembly and assembly efficiency is high;
[0030] In addition, because the connector and the push-lock structure are buckled, the lens is still connected to the lamp body when the frame is opened, which can prevent the lens from falling off the lamp body during the opening of the frame, thereby protecting the lens.
[0031] The above summary is only for the purpose of the specification and is not intended to be limiting in any way.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0039] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.
[0040] Referring to Figures 1 - 4 , there is shown a lamp with a detachable and replaceable lens according to a preferred embodiment of the present invention, including:
[0041] A lamp body 1, on which a mounting part 11 is provided, and a mounting groove 12 is provided in the middle of the mounting part 11;
[0042] The lamp panel 2 is disposed on the mounting portion 11 to expose the mounting groove 12;
[0043] The lens 3 is disposed on the top surface of the lamp panel 2, and a connecting member 31 is provided in the middle of the lens 3;
[0044] The pressing frame 4 is pivotally provided on the lamp body 1 so that the pressing frame 4 can be flipped relative to the lamp body 1. The pressing frame 4 is arranged around the mounting portion 11, and the upper edge of the pressing frame 4 is in close contact with the lens 3 to press the lens 3 against the lamp body 1;
[0045] The buckle structure 5 is provided between the lamp body 1 and the pressing frame 4. When the upper edge of the pressing frame 4 is in close contact with the lens 3, the buckle structure 5 fixes the lamp body 1 and the pressing frame 4, and further fixes the lens 3 on the lamp body 1; and
[0046] The push-button lock structure 6 is provided in the mounting groove 12. The push-button lock structure 6 has a locked state of engaging with the connecting member 31 and an unlocked state of releasing the connecting member 31. The push-button lock structure 6 can be pressed to switch between the locked state and the unlocked state.
[0047] For the lamp of the present invention, since the connecting member 31 is provided in the middle of the lens 3 and the push-button lock structure 6 is provided on the lamp body 1, during installation, the edge of the lens 3 can be pressed by the pressing frame 4, so that the edge and the parts near the edge of the lens 3 can be in close contact with the lamp panel 2. At the same time, the middle of the lens 3 can be tightened by engaging the connecting member 31 and the push-button lock structure 6, so that the middle and the parts near the middle of the lens 3 can be in close contact with the lamp panel 2 or tend to be in a state of fitting with the lamp panel 2, thereby eliminating or reducing the deformation of the lens 3, effectively preventing the lens 3 from deforming, enabling the lens 3 to have better optical performance, and thus improving the lighting effect of the lamp;
[0048] In addition, using the pressing frame 4 in cooperation with the buckle structure 5 to press the edge of the lens 3 against the lamp panel 2 and using the connecting member 31 and the push-button lock structure 6 to tighten the middle of the lens 3 against the lamp panel 2 are both detachable methods. During installation, place the lens 3 on the lamp panel 2 and press the lens 3 to engage the connecting member 31 and the push-button lock structure 6, then flip down the pressing frame 4 and fasten the buckle structure 5 to complete the installation. During disassembly, unlock the buckle structure 5, then flip open the pressing frame 4, and finally press the lens 3 to disengage the connecting member 31 and the push-button lock structure 6. The operation is simple, the disassembly and assembly are convenient, and the disassembly and assembly efficiency is high;
[0049] In addition, since the connecting member 31 and the push-button lock structure 6 are engaged, the lens 3 is still connected to the lamp body 1 when the pressing frame 4 is flipped open, which can prevent the lens 3 from falling off the lamp body 1 during the process of flipping open the pressing frame 4, and thus can play a role in protecting the lens 3.
[0050] In one embodiment, when the push-type locking structure 6 is in the locked state, the bottom of the lens 3 is in close contact with the lamp board 2, so that the lens 3 and the lamp board 2 are fitted together, thereby reducing the deformation amount of the lens 3 and effectively preventing the lens 3 from deforming.
[0051] See Figure 1 , in one embodiment, the mounting portion 11 is a groove structure, and the mounting portion 11 can at least accommodate the lamp board 2 to position the lamp board 2 and ensure that the lamp board 2 is mounted at a set position.
[0052] See Figure 2 , a relief hole 21 is provided in the middle of the lamp board 2. The relief hole 21 penetrates through the lamp board 2 vertically. The relief hole 21 is located above the mounting groove 12 and communicates with the mounting groove 12. The relief hole 21 is used for the end portion of the connecting member 31 to pass through to avoid the end portion of the connecting member 31, so that the end portion of the connecting member 31 can cooperate with the push-type locking structure 6.
[0053] See Figure 2 , in one embodiment, a first positioning structure 32 is further provided on the lens 3, and a second positioning structure 22 is provided on the lamp board 2. The second positioning structure 22 cooperates with the first positioning structure 32. In this way, the lens 3 can be guided for installation by the cooperation of the first positioning structure 32 and the second positioning structure 22, so that the lens 3 can be installed at a set position, ensuring that the protrusion on the lens 3 is aligned with the corresponding lamp beads on the lamp board 2 to prevent deviation, thereby improving the lighting effect of the present lamp. At the same time, the connecting member 31 and the push-type locking structure 6 can be quickly aligned, and thus the installation efficiency can be improved.
[0054] See Figure 2 , in one embodiment, the number of the first positioning structure 32 and the second positioning structure 22 is two. The two first positioning structures 32 are respectively disposed at the diagonal positions of the lens 3, and each second positioning structure 22 cooperates with a corresponding first positioning structure 32. In this way, it can not only play a better positioning role for the lens 3, but also avoid the problem of too long installation positioning operation time caused by too many first positioning structures 32 and second positioning structures 22, and thus the installation efficiency of the lens 3 can be improved.
[0055] Of course, in other embodiments, the number of the first positioning structure 32 and the second positioning structure 22 can be one or three or more, as long as it can play an installation positioning role for the lens 3.
[0056] See Figure 2, in one embodiment, among the first positioning structure 32 and the second positioning structure 22, one is a positioning post and the other is a positioning hole. The cooperation of the positioning post and the positioning hole can not only play a guiding role in installation, but also play a certain limiting role on the lens 3, which can effectively prevent the lens 3 from being offset relative to the lamp board 2 or the lens 3 from falling off the lamp board 2.
[0057] Of course, in other embodiments, among the first positioning structure 32 and the second positioning structure 22, one is a groove structure and the other is a convex structure, or both are convex structures.
[0058] See Figure 4 , in one embodiment, the push-button locking structure 6 includes:
[0059] A mounting seat 61, on which a positioning groove 611 is provided;
[0060] A locking member 62, which is movably inserted into the positioning groove 611. The locking member 62 has a locking portion 621. The locking portion 621 has a retracted state received in the positioning groove 611 and an extended state extending out of the positioning groove 611. When the locking portion 621 is in the retracted state, it is engaged with the connecting member 31, and when the locking portion 621 is in the extended state, it releases the connecting member 31; and
[0061] An elastic member 63, which is located between the locking member 62 and the bottom wall of the positioning groove 611. The elastic member 63 connects the locking member 62 and the mounting seat 61. The elastic member 63 is used to provide elastic force to the locking member 62 when the locking portion 621 switches from the retracted state to the extended state. That is, when pressing the lens 3, the lens 3 presses the connecting member 31, and then the connecting member 31 presses the locking member 62. The locking member 62 is pressed and moves downward along the positioning groove 611. The locking member 62 moves downward and compresses the elastic member 63, so that the elastic member 63 stores energy. At this time, the locking member 62 is in the retracted state and the locking portion 621 engages the connecting member 31. When pressing the lens 3 again, the lens 3 presses the connecting member 31, and then the connecting member 31 presses the locking member 62. The locking member 62 is pressed and moves downward along the positioning groove 611 to unlock from the mounting seat 61. The elastic member 63 resets and pushes the locking member 62 to move upward along the positioning groove 611, so that the locking portion 621 extends out of the positioning groove 611 to release the connecting member 31, realizing the unlocking of the connecting member 31, so that the lens 3 can be removed from the lamp board 2. This push-button locking structure 6 is simple and practical, convenient to operate, highly reliable, and small in size, which can avoid occupying too much installation space and make the installation more convenient.
[0062] See Figure 4, in one embodiment, the latch portion 621 has a receiving area 622. The receiving area 622 accommodates the end of the connecting member 31. The top opening of the receiving area 622 shrinks when the latch portion 621 is in the retracted state to clamp the end of the connecting member 31, thereby restricting the end of the connecting member 31 from disengaging from the receiving area 622. The top opening of the receiving area 622 enlarges when the latch portion 621 is in the extended state to release the end of the connecting member 31, enabling the end of the connecting member 31 to disengage from the receiving area 622. That is, the latch portion 621 has a variable diameter structure. When in the retracted state, the inner diameter of the latch portion 621 becomes smaller, and thus the end of the connecting member 31 can be clamped. When in the extended state, the latch portion 621 is no longer restricted by the positioning groove 611, and its inner diameter becomes larger, thereby releasing the end of the connecting member 31.
[0063] See Figure 4 , in one embodiment, the latch portion 621 has two latch arms 6211. The two latch arms 6211 are spaced apart and enclose the receiving area 622. Due to the spaced-apart arrangement and the elasticity of their own materials, when the latch portion 621 is in the retracted state, the latch arms 6211 can reliably clamp the end of the connecting member 31 under the restricting action of the positioning groove 611. When the latch portion 621 is in the extended state, the latch arms 6211 disengage from the restricting action of the positioning groove 611 and open, thereby releasing the end of the connecting member 31. The structure is simple and practical, with high reliability.
[0064] Of course, in other embodiments, the number of the latch arms 6211 can be three or more.
[0065] See Figure 4 , in one embodiment, a first limiting portion 311 is provided on the end of the connecting member 31, and a second limiting portion 6212 is provided on the latch arm 6211. The second limiting portion 6212 abuts against the first limiting portion 311, enabling the latch portion 621 to reliably clamp the end of the connecting member 31, thereby restricting the end of the connecting member 31 from disengaging from the receiving area 622. The structure is simple and practical, with high reliability.
[0066] In one embodiment, a first positioning portion (not shown in the figure) is provided on the mounting seat 61, and a second positioning portion (not shown in the figure) is provided on the latch arm 6211. The second positioning portion cooperates with the first positioning portion when the latch portion 621 is in the retracted state to position the latch portion 621, restricting the latch portion 621 from protruding out of the positioning groove 611, thereby maintaining the latch portion 621 in the retracted state.
[0067] See Figure 4 , in one embodiment, the elastic member 63 is a spring. Of course, in other embodiments, the elastic member 63 can also be an elastic structure such as a spring sheet.
[0068] SeeFigures 2 - 4 Moreover, the push - type locking structure 6 further includes a pressing plate 7 and a fastener 8. The pressing plate 7 abuts against the mounting base 61. The pressing plate 7 has a connection hole which cooperates with the mounting base 61. The fastener 8 connects the pressing plate 7 and the lamp body 1 together to fix the mounting base 61 on the lamp body 1.
[0069] Of course, in other embodiments, the above - mentioned push - type locking structure 6 can specifically adopt a pressing structure similar to that applied to a ballpoint pen to control the extension or retraction of the ballpoint pen refill.
[0070] See Figures 1 - 2 , the snap - fit structure 5 includes a buckle 51 and a snap - fitting portion 52. The snap - fitting portion 52 is provided on the pressing frame 4. One end of the buckle 51 is pivotally provided on the lamp body 1, so that the buckle 51 can be turned up and down relative to the lamp body 1, and thus the other end of the buckle 51 can be snap - fitted or disengaged from the snap - fitting portion 52. This snap - fit structure 5 has high snap - fit reliability and can ensure that the pressing frame 4 can firmly press the lens 3.
[0071] Of course, in other embodiments, the snap - fit structure 5 can include a male buckle and a female buckle. The male buckle is provided on the lamp body 1 and the female buckle is provided on the pressing frame 4, which can also achieve reliable snap - fit between the pressing frame 4 and the lamp body 1.
