The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

The utility model provides a lighting lamp 10 with a splicing function, which comprises a lamp body 100 and a connecting fitting 200 as shown in fig. 1. As shown in fig. 2 and 3, the lamp body 100 is provided with a plurality of connection slots 110, the plurality of connection slots 110 are symmetrically distributed on the side wall of the lamp body 100, and the connection fitting 200 is detachably inserted into the connection slot 100. During the splicing, the two ends of the connection fitting 200 are respectively inserted into the connection slots 110 of the two lamp bodies 100, so as to realize convenient splicing of the lamp bodies 100 (as shown in fig. 5).

As shown in fig. 3 and 4, the connection slot 110 is provided with a blocking wall 111, the connection fitting 200 is provided with a clamping arm 210 matched with the blocking wall 111, and the clamping arm 210 is provided with a waist-shaped through hole 211. When plugging, the retaining arm 210 of the connection fitting 200 enters the connection slot 110, and the retaining arm 210 is blocked by the blocking wall 111 and cannot be laterally separated from the connection slot 110 (can only be withdrawn from the opening direction of the connection slot 110). Moreover, after the connection fitting 200 is inserted into the connection slot 110, the retaining arm 210 is slightly deformed, and then abuts against the inner wall of the connection slot 110, so that the provision of the waist-shaped through hole 211 provides a necessary condition for the retaining arm 210 to deform.

Meanwhile, a coupling hole 201 is opened at one side of the connection fitting 200. The coupling hole 201 may be engaged with the external bracket 20 (shown in fig. 8) to stably mount the lamp body 100 on the bracket 20.

When in use, a user can select the splicing mode of the lamp body 100 by changing the matching of the connecting fitting 200 and the lamp body 100 according to the needs:

for example, when two lamp bodies 100 are to be spliced together (as shown in fig. 5), a user first inserts one end of the connection fitting 200 into the connection slot 110 on one side of the first lamp body 100, and then inserts the other end of the connection fitting 200 into the connection slot 110 of the second lamp body 100. After plugging, the retaining arm 210 of the connection fitting 200 is blocked by the blocking wall 111 and cannot be separated laterally, and the retaining arm 210 is extruded with the inner wall of the connection slot 110, and is affected by friction force, so that the connection fitting 200 is not easy to withdraw from the opening of the connection slot 110. Thus, the rapid splicing of the two lamp bodies 100 can be realized, and the connecting fitting 200 and the connecting slot 110 are matched, so that the two lamp bodies 100 are not easy to shake or separate after being spliced, and the splicing stability is improved. Similarly, by adding the connecting fitting 200 on the other side of the second lamp body 100, more lamp bodies 100 can be spliced. The splicing of the plurality of lamp bodies 100 may extend either laterally or longitudinally; of course, matrix stitching can also be implemented as long as enough luminaire bodies 100 are used;

for another example, when the lamp body 100 and the bracket 20 need to be spliced, the user first inserts the end of the connection fitting 200 without the coupling hole 201 into the connection slot 110 (as shown in fig. 7 and 8), and the coupling hole 201 faces out of the lamp body 100 after insertion. Then, the user performs the splicing of the bracket 20 and the connection fitting 200 through the coupling hole 201. The coupling hole 201 may be threaded, and the bracket 20 is screwed with the connection fitting 200.

In the present embodiment, the inner wall of the connection socket 110 is inclined inwards, and when the connection socket 110 is plugged, the inner wall of the connection socket 110 presses the retaining arm 210 of the connection fitting 200. Thus, when the connection fitting 200 is inserted into the connection slot 110, the retaining arm 210 is slightly deformed by being pressed, and as the inner wall of the connection slot 110 is inclined inwards, the deformation of the retaining arm 210 becomes more obvious as the connection fitting 200 is inserted. The deformed clamping arm 210 is tightly abutted against the inner wall of the connecting slot 110, and a large friction force is generated between the clamping arm and the connecting slot due to extrusion, so that the connecting fitting 200 is not easy to separate from and slide out from the opening of the connecting slot 110;

further, as shown in fig. 6, the edge of the catch arm 210 is a circular arc shape with a convex center. That is, the edge of the retaining arm 210 is olive-shaped with two large ends, so that the edge of the retaining arm 210 forms an arc, so that the edge of the retaining arm 210 has a certain guiding function during plugging, and the connection fitting 200 can be plugged into the connection slot 110 more easily. Meanwhile, the radian of the edge of the clamping arm 210 is matched with the inner wall of the inward inclined connecting slot 110, so that when the connecting fitting 200 is just plugged into the connecting slot 110, a gap exists between the clamping arm 210 and the inner wall of the connecting slot 110, and the plugging of the connecting fitting 200 is not blocked; when the connection fitting 200 is pressed deep into the connection slot 110, the gap between the catch arm 210 and the inner wall of the connection slot 110 is rapidly closed, so that the connection fitting 200 can be pressed together with the inner wall of the connection slot 110 only by traveling a short distance.

Further, it was found that, in the course of actual use, when the connection fitting 200 is spliced with the bracket 20 a plurality of times, the inner wall of the coupling hole 201 is easily worn, resulting in loosening of the connection. For example, the coupling hole 201 is screwed to the bracket 20, and after a plurality of splices, the threads on the inner wall of the coupling hole 201 are worn, which may result in the connection fitting 200 being not firmly spliced to the bracket 20, or even the connection fitting 200 being not connected to the bracket 20, and the connection stability is reduced. In order to solve the above-described problems, the present utility model has been devised specifically for the connection fitting 200.

Specifically, as shown in fig. 9, the connection fitting 200 includes a base 220 and a sleeve 230, the coupling hole 201 is provided at one side of the base 220, the sleeve 230 is installed in the coupling hole 201, and threads are provided on an inner wall of the sleeve 230. The outer wall of the sleeve 230 is provided with plum blossom teeth 231 and a middle limit groove 232, the coupling hole 201 of the base 220 is internally provided with tooth grooves 221 and convex ribs 222, and the tooth grooves 221 are matched with the plum blossom teeth 231 to prevent the sleeve 230 from rotating in the coupling hole 201; the rib 222 cooperates with the intermediate limit groove 232 to limit axial movement of the sleeve 230.

In this embodiment, the base 220 of the connection fitting 200 is mated with the connection socket 110, and the base 220 is not in direct contact with the bracket 20, but is in indirect contact with the bracket 20 through the sleeve 230. The design is that the base 220 is slightly deformed when being matched with the connecting slot 110, and the material is softer; if the coupling hole 201 of the base 220 is directly in contact with the bracket 20, the coupling hole 201 is easily worn after a plurality of splices. After the sleeve 230 is indirectly contacted, the sleeve 230 does not need to be deformed, and can be made of harder materials, so that abrasion in the splicing process is reduced or prevented, and the connecting fitting 200 can still have good connecting stability after being spliced for a plurality of times.

It should be noted that, between the base 220 and the sleeve 230, the tooth grooves 221 are matched with the plum blossom teeth 231, and the rib 222 is matched with the middle limit groove 232, so that the sleeve 230 is limited, so that the sleeve 230 is firmly limited in the coupling hole 201. Thus, after the connection fitting 200 is spliced with the bracket 20 through the sleeve 230, the connection fitting 200 is not connected with the bracket 20 stably due to the movement of the sleeve 230 in the coupling hole 201.

Preferably, the sleeve 230 is a metal structure, and the base 220 is an integrally formed plastic structure. The metal sleeve 230 can reduce or prevent the abrasion during the splicing, while the plastic base 220 can have better elastic deformation and provide a larger friction coefficient during the extrusion. In the production process, the sleeve 230 is first produced, then the sleeve 230 is placed in an injection mold of the base 220, and finally the base 220 is injection molded. In this way, the sleeve 230 may be wrapped in the base 220, thereby achieving connection of the sleeve 230 to the base 220.

Further, it is found that, after a period of time, the deformability of the retaining arm 210 of the connection fitting 200 is degraded, and the edge of the retaining arm 210 is worn to some extent, which makes the connection fitting 200 inserted into the connection slot 110 easily separate from the opening direction, thereby reducing the splice stability. In order to overcome the above technical problems, the present utility model has been specially designed to enable the connection fitting 200 to maintain good connection stability for a long period of time.

Specifically, as shown in fig. 10, 12 and 13, a locking assembly 300 is disposed inside the lamp body 100, and the locking assembly 300 is used for limiting the connection fitting 200 inserted into the connection slot 110. Wherein, the locking assembly 300 comprises: the lamp comprises a positioning nail 310, a main body sliding part 320 and an extending elastic part 330, wherein the positioning nail 310 is fixedly arranged on the lamp body 100, the main body sliding part 320 is arranged in the lamp body 100 in a sliding mode through the positioning nail 310, and the extending elastic part 330 is arranged between the main body sliding part 320 and the positioning nail 310. The main body sliding member 320 is provided with a locking pin 321; the locking pin 321 can movably enter the connecting slot 110 and be inserted into the waist-shaped through hole 211 of the connecting fitting 200, so as to realize locking limit of the connecting fitting 200.

In this embodiment, as shown in fig. 13, the main body sliding member 320 is provided with a sliding slot 322, the positioning pin 310 is disposed through the sliding slot 322, and the number of the positioning pins 310 and the number of the sliding slots 322 are two. Thus, the two sets of positioning pins 310 cooperate with the sliding grooves 322 to realize stable sliding of the main body sliding member 320, and the sliding grooves 322 provide limiting and guiding effects for sliding of the main body sliding member 320. Meanwhile, the body slider 320 is provided with two hinge posts 323, and the two hinge posts 323 are respectively connected with the two positioning pins 310 through the extension elastic members 330.

Preferably, as shown in fig. 11 and 12, the main body slider 320 is provided with a lever 324, and the lever 324 is disposed through the lamp body 100 and extends to the outside of the lamp body 100. In this way, the user can control the body slider 320 to slide through the lever 324.

The following describes the operation of the locking assembly 300 in conjunction with the above-described structure:

in the initial state, as shown in fig. 10, the locking assembly 300 is in a state in which the main body slider 320 is accommodated in the lamp body 100 and the extension elastic member 330 is in an extended state;

when the connection fitting 200 is inserted into the connection slot 110, the clamping arm 210 is pressed to slightly deform, and the waist-shaped through hole 211 is deformed (i.e., the waist-shaped through hole 211 is not closed). The user then toggles the lever 324 to cause the body slider 320 to slide toward the connection slot 110. During the state change of the locking assembly 300 as shown in fig. 14, as the body slider 320 slides, the distance between the hinge post 323 and the positioning pin 310 is first shortened, and the extension elastic member 330 is compressed; then, after the hinge post 323 passes from the right side to the left side of the positioning nail 310 (as shown in fig. 14), the distance between the hinge post 323 and the positioning nail 310 increases again, and the extension elastic member 330 is changed back to the unfolded state;

at this time, the body slider 320 approaches the connection slot 110, the locking pin 321 thereon is penetrated into the connection slot 110, and the locking pin 321 is just penetrated into the waist-shaped through hole 211 of the connection fitting 200. Thus, the lock pin 321 cooperates with the waist-shaped through hole 211 to limit the connection fitting 200, thereby preventing the connection fitting 200 from sliding out of the opening of the connection slot 110;

when the user needs to detach, he or she toggles the lever 324 in the opposite direction, so that the main body slider 320 slides in the opposite direction, and the lock pin 321 can retract and no longer clamp the waist-shaped through hole 211. Thus, the connection fitting 200 can be withdrawn from the opening of the connection slot 110, so as to release the splice between the lamp bodies 100.

The operation of the latch assembly 300 is now described.

It is emphasized that the locking assembly 300 of the present utility model has the following features and functions:

first, the provision of the stretch elastic 330 provides better tactile feedback to the user. When the user starts to toggle the main body slider 320, the extension elastic member 330 is gradually compressed, and the pushing force required by the extension elastic member is gradually increased; and when the hinge post 323 passes over the position of the positioning pin 310, the expansion elastic member 330 is actively changed from the compressed state to the expanded state, so that the user can not apply any force. Thus, the user can obviously feel a jerky feeling when dialing the main body sliding piece 320, so that whether the main body sliding piece 320 is pushed in place can be clearly judged;

secondly, due to the extension elastic member 330, when the locking assembly 300 is not subjected to external force, the extension elastic member 330 is in the unfolded state, so that the hinge post 323 and the positioning pin 310 are separated from each other as far as possible. Thus, with the elastic force support of the extension elastic member 330, the body slider 320 is not easily shaken, and even if the body slider 320 is collided or erroneously touched, the extension elastic member 330 can autonomously reset the body slider 320 so that the body slider 320 is stably maintained in the current state as long as the extension elastic member 330 is not overcome and the hinge post 323 passes over the positioning pin 310;

thirdly, the locking assembly 300 has a simple and reliable structure, which can reduce the manufacturing cost and facilitate the operation and subsequent maintenance of the user.

In another embodiment, in order to enable the lighting fixture 10 with the splicing function of the present utility model to be suspended conveniently, the fixture body 100 is provided with a hook 120 (as shown in fig. 2). The end of the hook 120 is hinged to the lamp body 100, and a receiving groove 101 (as shown in fig. 11) for receiving the hook 120 is formed in the back surface of the lamp body 100.

Thus, the hook 120 can rotate on the lamp body 100, and when the lamp is required to be used, the hook 120 rotates to extend out; when not in use, the hook 120 can be rotated to the back of the lamp body 100 to facilitate storage.

In summary, according to the lighting fixture 10 with the splicing function, the splicing combination structure and the splicing combination mode can be replaced according to the needs, and meanwhile, the lighting fixture has high connection stability and is convenient to operate.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model.
