In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] refer to Figure 1-Figure 11 As shown, in the embodiment of the utility model, a lamp is proposed, which is mainly suitable for occasions where the internal cable and the external cable of the lamp are connected through a wiring connector. The wiring connector belongs to the prior art and needs to be assembled and fixed on the lamp through an internal nut, which will not be described in detail here. It can be understood that the lamp can be used in general occasions where lighting is required, and can also be used in special occasions where the sealing performance of the lamp itself is required to be high. In other words, whether the lamp has a sealing structure is not a limitation of the embodiment of the utility model.

[0035] The lamp includes a lampshade 10, a connection seat 20 and a locking structure. The lampshade 10 is set as a closed structure, and a cavity is set inside. The cavity is installed with structures including but not limited to a light source and internal cables connected to the light source. The light source can be an LED light board or a lamp tube, a lamp bead, etc., which is not specifically limited here. In order to quickly connect the internal cable with the external cable outside the lampshade 10, a threading opening 121 connecting the cavity and the outside is opened on the lampshade 10. The locking structure is configured to fix the connection seat 20 in the lampshade 10. The connection seat 20 is opened with a threaded hole 24 coaxial with the threading opening 121. The wiring connector can pass through the threading opening 121 and be threadedly connected to the connection seat 20.

[0036] In the above-mentioned lamp, a locking structure is used to fix the connecting base 20 with a threaded hole 24 inside the lampshade 10. When connecting the internal cable and the external cable, it is only necessary to lead the internal cable out of the lampshade 10 through the threading opening 121 and connect it to the external cable on the wiring connector, and then insert the wiring connector into the cavity through the threading opening 121. The connection between the wiring connector and the connecting base 20 can be achieved by screwing the wiring connector. The wiring connector can be assembled on the lampshade 10 without opening the lampshade 10. The operation is simple and the assembly time is short.

[0037] It is understandable that the threading opening 121 can be provided on the side wall of the lampshade 10 , or on the top wall or the bottom wall of the lampshade 10 .

[0038] refer to Figure 1 As shown, in some embodiments, the lampshade 10 is in the shape of a long strip extending along a first direction (X direction in the figure), and its cross-sectional shape along a second direction (Z direction in the figure) can be circular, rectangular or other shapes, without specific limitation here, and the second direction is perpendicular to the first direction. Specifically, the lampshade 10 includes a first shell 11 and a second shell 12 distributed along the second direction, wherein the first shell 11 has an opening toward the second shell 12, and the second shell 12 has an opening toward the first shell 11, and the first shell 11 and the second shell 12 are connected by means including but not limited to snap-fitting and screwing to enclose and form a cavity, and when a seal is required, a sealing ring is also provided between the first shell 11 and the second shell 12.

[0039] Taking the example of the threading opening 121 being opened on any side wall of the lampshade 10 along the first direction, in some embodiments, the locking structure includes a matching limit slot seat and a limit plug block 60, and a plurality of limit slot seats are spaced apart and distributed on the opposite sides of the connecting seat 20 along the third direction and abut against the opposite sides of the connecting seat 20. A limit slot extending along the third direction is opened on the limit slot seat, and the limit plug block 60 is arranged on the side of the connecting seat 20 along the third direction and is plugged in and matched with the limit slot on the limit slot seat one by one. It should be emphasized that the limit plug block 60 is in contact with the bottom of the limit slot.

[0040] The plug-in cooperation between the limit groove seat and the limit plug block 60 limits the movement of the connecting seat 20 along the first direction, and the contact between the limit plug block 60 and the bottom of the limit groove limits the rotation of the connecting seat 20 around its own axis. At the same time, the limit groove seats arranged on the opposite sides of the connecting seat 20 along the third direction and abutting against the connecting seat 20 also limit the movement of the connecting seat 20 along the third direction.

[0041] In order to prevent the limiting plug 60 from being separated from the limiting groove seat, that is, to prevent the connecting seat 20 from moving in the second direction, the locking structure further includes a limiting block 70, which can be arranged on the connecting seat 20 or on the side wall of the lampshade 10. For example, the limiting block 70 is arranged on the side wall of the lampshade 10 where the threading opening 121 is provided and abuts against the side of the connecting seat 20 away from the bottom wall of the lampshade 10, and the side of the limiting block 70 away from the bottom wall of the lampshade 10 gradually tilts toward the bottom wall of the lampshade 10 from one end connected to the side wall to the end away from the side wall. When the limiting plug 60 moves toward the limiting groove seat, the connecting seat 20 squeezes the guide surface of the limiting block 70 to deform the limiting block 70, until the connecting seat 20 moves to the bottom of the limiting block 70 and abuts against the limiting block 70, and the limiting block 70 returns to its original shape, and cooperates with the groove bottom of the limiting groove seat to limit the connecting seat 20 in the second direction. Alternatively, the limit block 70 is disposed on the side of the connecting seat 20 facing the side wall where the threading opening 121 is provided. Unlike the limit block 70 disposed on the lampshade 10, the side of the limit block 70 facing the bottom wall where the threading opening 121 is located is gradually inclined from the end connected to the connecting seat 20 to the end away from the connecting seat 20 toward the bottom wall away from the lampshade 10. At this time, a limit card hole needs to be provided on the side wall of the lampshade 10. When the limit plug 60 moves toward the limit slot seat, the limit block 70 squeezes the side wall to deform the side wall until the limit block 70 is inserted into the limit card hole. Considering the sealing performance and processing difficulty of the lampshade 10, it is preferred that the limit block 70 is disposed on the side wall of the lampshade 10 and is integrally formed with the side wall of the lampshade 10.

[0042] At this time, based on the limit card block 70 and the cooperating limit slot seat and limit plug block 60, the connecting seat 20 is fixed in the lampshade 10. When connecting the internal cables and the external cables, it is only necessary to screw the wiring connector self-threading opening 121 onto the connecting seat 20 without opening the lampshade 10.

[0043] In some embodiments, the limiting plug 60 includes a first limiting plug 60a and a second limiting plug 60b, wherein the first limiting plug 60a is fixed to a side of the connecting seat 20 away from the bottom wall of the lampshade 10, and the second limiting plug 60b is fixed to a side of the connecting seat 20 close to the bottom wall of the lampshade 10. Correspondingly, the limiting groove seat includes a first limiting groove seat and a second limiting groove seat, the limiting groove on the first limiting groove seat is for the first limiting plug 60a to be inserted, the limiting groove on the second limiting groove seat is for the second limiting plug 60b to be inserted, and the end surface of the second limiting groove seat away from the bottom wall abuts against the connecting seat 20, so as to better limit the rotation of the connecting seat 20.

[0044] In some embodiments, the cross-section of the first limit slot gradually increases from the bottom of the slot to the slot direction where the connecting seat 20 is inserted. This arrangement can not only reduce the difficulty of inserting the first limit plug 60a into the first limit slot, but also reduce the difficulty of moving the connecting seat 20 to the bottom of the limit block 70 or the difficulty of the limit block 70 being inserted into the limit hole.

[0045] In some embodiments, two first limit blocks 60a and two second limit blocks 60b are provided, and are symmetrically arranged on both sides of the connecting seat 20 along the third direction. Two first limit slot seats and two second limit slot seats are also provided, and are symmetrically arranged on both sides of the threading opening 121 along the third direction. In some other embodiments, one first limit block 60a and one second limit block 60b can also be provided, and are respectively located on both sides of the connecting seat 20 along the third direction. Or two first limit blocks 60a are provided, and one second limit block 60b is provided. Or one second limit block 60b is provided, and two second limit blocks 60b are provided. In summary, as long as the limit blocks 60 and the limit slot seats cooperating with the limit blocks 60 are provided on both sides of the connecting seat 20 along the third direction, it is sufficient, for example, only two first limit blocks 60a or only two second limit blocks 60b are provided.

[0046] refer to Figure 7 and Fig. 9 As shown, under the premise that both the first limiting plug 60a and the second limiting plug 60b are provided, the connection seat 20 is mushroom-shaped as a whole, including a cover and a handle, the two first limiting plugs 60a are located on opposite sides of the cover, and the two second limiting plugs 60b are located on opposite sides of the handle. At this time, the first limiting groove seat abuts against the opposite sides of the cover, and the second limiting groove seat abuts against the opposite sides of the handle and its side away from the bottom wall abuts against the cover. Specifically, the bottom of the limiting groove on the first limiting groove seat and the axis of the threaded hole 24 are on the same straight line to ensure uniform force when screwing the wiring connector.

[0047] In order to prevent the connection seat 20 from occupying too much space in the lampshade 10, the connection seat 20 is arranged to fit the side wall of the lampshade 10 with the threading opening 121. In order to prevent the limiting groove seat from affecting the installation of other components in the lampshade 10, the thickness of the limiting plug 60 along the first direction is less than the thickness of the connection seat 20 along the first direction. More specifically, the limiting plug 60 fits the side wall with the threading opening 121. Based on this, the lamp includes a first limiting seat 80a, and the first limiting seat 80a and the side wall with the threading opening 121 are integrally injection molded. The first limiting seat 80a is L-shaped so as to cooperate with the side wall to form a limiting groove opened on the first limiting groove seat. Specifically, in order to further reduce the processing difficulty of the first limiting seat 80a and improve the structural strength of the first limiting seat 80a, the first limiting seat 80a is connected to the bottom wall of the lampshade 10.

[0048] The lamp also includes a second limit seat 80b, which is integrally injection-molded with the bottom wall of the lampshade 10. The second limit seat 80b and the side wall with the threading opening 121 cooperate with the bottom wall to form a second limit groove seat, and there is a gap between the second limit seat 80b and the side wall with the threading opening 121 to form a limit groove opened on the second limit groove seat.

[0049] In some embodiments, the connection seat 20 is processed by using an internal nut connected to a wiring connector in the prior art, and the connection seat 20 and the limiting plug 60 are formed simultaneously by thinning the four corners of the internal nut. The first limiting seat 80a, the second limiting seat 80b and the limiting block 70 can be molded for a second time based on an existing lamp model and integrally formed with the lampshade 10, with low modification cost. Other components in the lampshade 10 can also adopt existing structures, sizes and shapes without modification.

[0050] In some embodiments, in order to prevent foreign objects from entering the interior of the lamp through the threading opening 121 during transportation or storage, the lamp further includes a cover 40, which is detachably connected to the lampshade 10 and seals the threading opening 121. For example, the outer peripheral surface of the cover 40 has an external thread, and the cover 40 can be inserted into the threading opening 121 and threadedly connected to the connection base 20.

[0051] refer to Fig.10 and Fig.11 As shown, in some embodiments, the cover 40 can be made of existing screws, such as cross-slot screws. When wiring is required, the cover 40 can be screwed off from the lampshade 10.

[0052] It is understandable that when wiring, the internal cable in the lampshade 10 needs to be taken out from the lampshade 10, then connected to the external cable on the wiring connector, and then inserted back into the lampshade 10. Therefore, in some embodiments, the internal cable is detachably connected to the cover 40. For example, a slot for inserting the internal cable is provided at one end of the cover 40 inserted into the lampshade 10, and the end of the internal cable away from the light source is inserted into the slot. When the cover 40 is separated from the lampshade 10 and moves in a direction away from the lampshade 10, the end of the internal cable away from the power source moves with the cover 40, thereby leaving and passing through the lampshade 10.

[0053] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
