Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a detachable connection device for lighting fixtures. Background Technology

[0002] Lighting fixture brackets are key components used for installing and supporting lighting fixtures, widely used in homes, commercial lighting, industrial plants, stages, and other applications. Traditional lighting fixture brackets typically consist of metal rods, fixed bases, and connectors, primarily functioning to suspend the lighting fixture and ensure stability. Currently, the brackets are bolted to the lamp body, making disassembly cumbersome. Furthermore, the overall packaging and transportation of these brackets and the lamp body results in excessively large packaging materials, making handling and transportation extremely inconvenient. Therefore, there is an urgent need for a easily detachable lighting fixture bracket to address the shortcomings of existing technology. Summary of the Invention

[0003] To solve one of the above-mentioned technical problems, the present invention provides a detachable connection device for lamps, which can be easily and flexibly disassembled and assembled, and is convenient for packaging and transportation.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0005] A detachable connection device for a lamp includes a lamp body and a connecting frame. Two slots extending axially along the outer periphery of the lamp body are provided opposite to each other. Each of the two connecting ends of the connecting frame is provided with a corresponding insert block that fits into the slot. The connecting frame is plugged into and out of the slot via the insert blocks. A stop assembly is provided between the lamp body and the connecting frame to stop or allow the insert blocks to be plugged in and out, thereby achieving a detachable connection between the lamp body and the connecting frame. A first elastic element is provided at the leading end of each insert block. When the stop assembly restricts the insert block from being pulled out, the first elastic element causes the insert block to abut against the stop assembly; when the insert block is no longer restricted by the stop assembly, the first elastic element causes the insert block to spring out of the slot.

[0006] In a preferred embodiment, the stop assembly includes a fixing plate and a stop pin. The fixing plate has a first groove, and the lamp body has a second groove corresponding to the first groove. When the fixing plate is fixedly connected to the lamp body by fasteners, the first groove and the second groove together form a sliding hole for the stop pin to slide back and forth. When the protruding end of the stop pin slides from the sliding hole into the slot, the stop pin can prevent the insert from being pulled out of the slot. When the stop pin is fully retracted into the sliding hole, the stop pin can allow the insert to be inserted or pulled out of the slot.

[0007] As a preferred embodiment, the stop pin is further defined as follows: a paddle is fixedly provided on the circumferential surface of the stop pin; the fixing plate has a limiting hole communicating with the sliding hole; the paddle passes through the limiting hole and slides back and forth in the limiting hole to drive the protruding end of the stop pin to slide from the sliding hole into the slot or completely retract into the sliding hole.

[0008] As a preferred embodiment, the insertion block is further defined as follows: the tail end of the insertion block is provided with a U-shaped groove, and after the insertion block is inserted into the slot, the protruding end of the stop pin slides out from the sliding hole, at which time the protruding end of the stop pin can abut against the U-shaped groove.

[0009] As a preferred embodiment, it is further defined that a second elastic element is provided in the sliding hole to keep the stop pin extended under non-external force.

[0010] In a preferred embodiment, the slot is further defined as follows: the slot is mainly composed of a first opening slot and a second opening slot with different widths, the width of the first opening slot being greater than the width of the second opening slot; the first opening slot and the second opening slot are sequentially arranged along the radial direction from the inside to the outside of the lamp body, so that the two side walls of the slot form symmetrical stepped surfaces; the insert is mainly composed of a first protrusion and a second protrusion with different widths, the width of the first protrusion being greater than the width of the second protrusion, so that the insert forms symmetrical stepped surfaces on both sides in the width direction; when the insert and the slot are inserted, the first protrusion and the first opening slot are adapted to each other, and the second protrusion and the second opening slot are adapted to each other, and the stepped surface and the stepped surface on the same side are in contact with each other.

[0011] In a preferred embodiment, the connecting frame further includes a first U-shaped bracket, a second U-shaped bracket, and two connecting shafts. The two ends of the first U-shaped bracket are respectively placed inside the two ends of the second U-shaped bracket. The connecting shaft passes through the ends of the first U-shaped bracket and the ends of the second U-shaped bracket from the outside to the inside and is then fixedly connected to the insert block.

[0012] As a preferred embodiment, the first U-shaped bracket is further defined as follows: the first U-shaped bracket is provided with a limiting post, and the second U-shaped bracket is provided with an arc-shaped hole adapted to the limiting post; the first U-shaped bracket is adapted to the arc-shaped hole of the second U-shaped bracket through the limiting post.

[0013] By adopting the above technical solution, the present invention has at least the following beneficial effects:

[0014] The detachable connection device includes a lamp body and a connecting frame. The outer circumference of the lamp body is provided with two slots extending along the axial direction of the lamp body. Both connecting ends of the connecting frame are provided with plugs that are adapted to the slots. The connecting frame is connected to the slots by plugging and unplugging the plugs. A stop component is provided between the lamp body and the connecting frame to stop or allow the plugs to be plugged and unplugged, thereby realizing the detachable connection between the lamp body and the connecting frame. This structure is simple in design, easy to replace and efficient, and more convenient in packaging and transportation. Attached Figure Description

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] In the description of this invention, it should be understood that the terms "center," "middle," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicating orientation or positional relationships are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0022] As attached Figure 1As shown, a detachable connection device for a lamp includes a lamp body 1 and a connecting frame 2. Two slots 11 extending axially along the outer periphery of the lamp body 1 are arranged opposite each other. Each of the two connecting ends of the connecting frame 2 is provided with a corresponding insert 21 that fits into the slot 11. The connecting frame 2 is plugged into and out of the slot 11 via the inserts 21. A stop assembly 3 is provided between the lamp body 1 and the connecting frame 2 to stop or allow the inserts 21 to be plugged in and out, thereby achieving a detachable connection between the lamp body 1 and the connecting frame 2. The first end of the insert 21 is connected to one end of a first elastic member 22, and the other end of the first elastic member 22 abuts against the side wall of the slot 11. When the stop assembly 3 restricts the insert 21 from being pulled out, the first elastic member 22 causes the insert 21 to abut against the stop assembly 3; when the insert 21 is no longer restricted by the stop assembly 3, the first elastic member 22 causes the insert 21 to spring out of the slot 11.

[0023] As attached Figure 2 and attached Figure 3 As shown, the stop assembly 3 includes a fixing plate 31 and a stop pin 32. The fixing plate 31 has a first groove 311, and the lamp body 1 has a second groove 100 corresponding to the first groove 311. When the fixing plate 31 is fixedly connected to the lamp body 1 by fasteners, the first groove 311 and the second groove 100 together form a sliding hole 10 for the stop pin 32 to slide back and forth. Of course, we can also provide only the first groove 311 on the fixing plate 31, or only the second groove 100 on the lamp body 1. Either design can realize the sliding setting of the stop pin 32. Preferably, the first groove 311 and the second groove 100 coexist to form the sliding hole 10, so that the stop pin 32 can slide stably and smoothly. Further, the sliding hole 10 is set on the inner wall of the slot 11, that is, the sliding hole 10 is opened in the radial direction of the lamp, so that the sliding hole 10 and the slot 11 are perpendicularly arranged.

[0024] As attached Figure 4As shown, when the protruding end of the stop pin 32 slides from the sliding hole 10 into the slot 11, the stop pin 32 can prevent the insert 21 from being pulled out of the slot 11; when the stop pin 32 is fully retracted into the sliding hole 10, the stop pin 32 can allow the insert 21 to be inserted or pulled out of the slot 11. A second elastic element 33 is provided in the sliding hole 10 to keep the stop pin 32 protruding under non-external force. Specifically, during installation, the insert 21 is first inserted into the slot 11. Under the action of the second elastic element 33, the protruding end of the stop pin 32 can automatically slide from the sliding hole 10 into the slot 11. At this time, the protruding end of the stop pin 32 and the insert 21 remain in contact, thus completing the fixed connection between the connecting frame 2 and the lamp body 1. During disassembly, the stop pin 32 is fully retracted into the sliding hole 10. At this time, the insert 21 loses the restriction of the stop pin 32 and is removed from the slot 11, thus completing the detachable connection between the connecting frame 2 and the lamp body 1.

[0025] As attached Figure 4 As shown, a paddle 321 is fixedly provided on the circumferential surface of the stop pin 32. The fixing plate 31 has a limiting hole 312 communicating with the sliding hole 10. The limiting hole 312 is used to limit the sliding range of the stop pin 32. The paddle 321 passes through the limiting hole 312 and slides back and forth in the limiting hole 312 to drive the protruding end of the stop pin 32 to slide from the sliding hole 10 into the slot 11 or completely retract into the sliding hole 10. The paddle 321 is used to manipulate the reciprocating movement of the stop pin 32 to facilitate switching the unlocking and locking of the stop pin 32.

[0026] As attached Figure 2 As shown, the tail end of the insert 21 is provided with a U-shaped groove 211. The tail end of the insert 21 refers to the end of the insert 21 that is close to the stop pin 32 after it is inserted into the slot 11. After the insert 21 is inserted into the slot 11, the protruding end of the stop pin 32 slides out from the sliding hole 10. At this time, the protruding end of the stop pin 32 can abut in the U-shaped groove 211. The U-shaped groove 211 can increase the fit with the protruding end of the stop pin 32 and facilitate the abutment of the stop pin 32 and the U-shaped groove 211.

[0027] As attached Figure 2 and attached Figure 4 As shown, the first end of the plug 21 is provided with a first elastic member 22 that can keep the U-shaped groove 211 of the plug 21 abutting against the protruding end of the stop pin 32. The first end of the plug 21 refers to the end of the plug 21 that is inserted into the slot 11. The first elastic member 22 helps to prevent the plug 21 from loosening in the axial direction of the lamp body 1, and keeps the tail end of the plug 21 abutting against the stop pin 32. In addition, when the plug 21 loses the abutment of the stop pin 32, the first elastic member 22 can also make the plug 21 spring up, that is, the tail end of the plug 21 is higher than the top of the slot 11, which makes it easier to remove the connecting bracket 2.

[0028] In this embodiment, the first elastic element 22 and the second elastic element 33 are elastic sheets or springs. Specifically, the first elastic element 22 is a V-shaped elastic sheet and the second elastic element 33 is a spring.

[0029] As attached Figure 3 and attached Figure 5 As shown, the slot 11 is mainly composed of a first opening slot 111 and a second opening slot 112 with different widths. The width of the first opening slot 111 is greater than the width of the second opening slot 112. The first opening slot 111 and the second opening slot 112 are arranged sequentially along the radial direction from the inside to the outside of the lamp body 1, so that the two side walls of the slot 11 form symmetrical stepped surfaces. The insert 21 is mainly composed of a first protrusion 212 and a second protrusion 213 with different widths. The width of the first protrusion 212 is greater than the width of the second protrusion 213, so that the insert 21 forms symmetrical stepped surfaces on both sides in the width direction. When the insert 21 and the slot 11 are inserted, the first protrusion 212 and the first opening slot 111 are adapted to each other, while the second protrusion 213 and the second opening slot 112 are adapted to each other. The stepped surfaces and stepped surfaces fit together, increasing the contact surface and adaptability between the insert 21 and the slot 11, and ensuring the sliding stability between them.

[0030] As attached Figure 5 As shown, the connecting frame 2 also includes a first U-shaped bracket 23, a second U-shaped bracket 24, and two connecting shafts 25. The two ends of the first U-shaped bracket 23 are respectively placed inside the two ends of the second U-shaped bracket 24. The connecting shafts 25 pass through the ends of the first U-shaped bracket 23 and the second U-shaped bracket 24 from the outside to the inside and are fixedly connected to the insert block 21. The first U-shaped bracket 23 and the second U-shaped bracket 24 are connected by the connecting shafts 25 and can rotate relative to each other. That is, the first U-shaped bracket 23 and the second U-shaped bracket 24 can support each other by spreading them apart, and the first U-shaped bracket 23 and the second U-shaped bracket 24 can be folded together or used for hoisting.

[0031] In this embodiment, the first U-shaped bracket 23 is provided with a limiting post 231, and the second U-shaped bracket 24 is provided with an arc-shaped hole 241 adapted to the limiting post 231. The first U-shaped bracket 23 adapts to the arc-shaped hole 241 of the second U-shaped bracket 24 through the limiting post 231 to limit the relative rotation angle between the first U-shaped bracket 23 and the second U-shaped bracket 24, and prevent the rotation angle between the two from being too large.

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
