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

[0033] refer to Figure 1-Figure 9 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 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.

[0034] 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 it. 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., and no specific restrictions are made here. In order to quickly connect the internal cable with the external cable outside the lampshade, 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.

[0035] 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.

[0036] In some embodiments, the locking structure includes a positioning hole 21 and a positioning column 30 that cooperate with each other, wherein one of the connection base 20 and the lampshade 10 is provided with the positioning hole 21, and the other is provided with the positioning column 30, and the positioning column 30 is plugged and fixed with the positioning hole 21, thereby achieving the locking between the connection base 20 and the lampshade 10. It should be noted that the positioning column 30 is completely inserted into the positioning hole 21 and does not protrude from the positioning hole 21, so that the positioning column 30 and the connection base 20 share the same space. Compared with the existing lamps, the positioning column 30 does not occupy additional space, so other structures in the lamp can adopt the existing structure, size and shape without modification.

[0037] Considering the limitation of the thickness of the lampshade 10 on the size of the positioning hole 21, in some embodiments, the positioning hole 21 is opened on the connecting seat 20, the positioning column 30 is fixed on the lampshade 10, and the positioning column 30 and the lampshade 10 are integrally injection molded. When the lamp in the embodiment of the utility model is actually produced, a secondary mold can be directly made based on the existing lamp model, and the modification cost is low. The connecting seat 20 can be obtained by cutting and drilling based on the existing nut.

[0038] 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 bottom wall of the lampshade 10. Correspondingly, the placement direction of the connecting seat 20 needs to be adaptively adjusted so that the threaded hole 24 and the threading opening 121 remain coaxial.

[0039] For example, the threading opening 121 is opened on the side wall of the lampshade 10, and the positioning column 30 is fixed on the bottom wall or top wall of the lampshade 10 and arranged close to the side wall of the lampshade 10. In this case, the positioning hole 21 is arranged perpendicularly to the threaded hole 24, and the positioning column 30 is also perpendicular to the threaded hole 24, so as to reduce the restriction of the space size of the cavity on the movement of the connecting seat 20 toward the positioning column 30. Or the threading opening 121 is opened on the bottom wall or bottom wall of the lampshade 10, and the positioning column 30 is also fixed on the top wall or bottom wall of the lampshade 10. In this case, the positioning hole 21 is arranged in the same direction as the threaded hole 24, and the positioning column 30 is also in the same direction as the threaded hole 24.

[0040] refer to Figure 1As shown, the lampshade 10 is configured as 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. In some embodiments, 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-on and screw-on to enclose and form a cavity. When a seal is required, a sealing ring is also provided between the first shell 11 and the second shell 12. At this time, the threading opening 121 is preferably opened on any end face of the first shell 11 or the second shell 12 along the length direction.

[0041] In order to improve the versatility of the connection base 20, refer to Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the connection seat 20 is set to be a thin sheet structure that is approximately rectangular, and the threaded hole 24 passes through the opposite sides of the connection seat 20 along the thickness direction of the connection seat 20. At the same time, the positioning hole 21 of the connection seat 20 includes a first positioning hole 21a and a second positioning hole 21b, the first positioning hole 21a is vertically arranged with the threaded hole 24, and the second positioning hole 21b is arranged in the same direction as the threaded hole 24. When the threading opening 121 is opened on the side wall of the lampshade 10, the placement direction of the connection seat 20 is adjusted so that the threaded hole 24 of the connection seat 20 is coaxial with the threading opening 121, and the positioning column 30 is plugged and matched with the first positioning hole 21a; when the threading opening 121 is opened on the bottom wall or the top wall of the lampshade 10, the placement direction of the connection seat 20 is adjusted so that the threaded hole 24 of the connection seat 20 is coaxial with the threading opening 121, and the positioning column 30 is plugged and matched with the second positioning hole 21b.

[0042] In some embodiments, in order to further improve the stability of the connection between the positioning hole 21 and the positioning column 30, two first positioning holes 21a and two second positioning holes 21b are provided, and are spaced apart and distributed on opposite sides of the threaded hole 24. Correspondingly, two positioning columns 30 are also spaced apart. Specifically, the spacing between the two positioning columns 30 is not less than 3.6 cm to adapt to the size of nuts on the market.

[0043] In some embodiments, the highest points of the two positioning posts 30 inserted into the first positioning hole 21a are in the same straight line with the axis of the threaded hole 24, and the two positioning posts 30 inserted into the second positioning hole 21b are arranged on both radial sides of the threaded hole 24 (that is, the second positioning hole 21b is arranged on both radial sides of the threaded hole 24) to ensure that the force is uniform when the wiring connector is screwed. More specifically, the first positioning hole 21a is arranged as a blind hole, and the closed end face of the blind hole is in the same straight line with the axis of the threaded hole 24, while the second positioning hole 21b is arranged on one side of the closed end of the blind hole, and the second positioning hole 21b is a through hole.

[0044] In order to achieve complete locking between the connecting base 20 and the lampshade 10 and prevent the threading hole 121 and the threaded hole 24 from being misaligned due to the movement of the connecting base 20 during transportation or installation, in some embodiments, the positioning column 30 and the positioning hole 21 are interference fit to simplify assembly.

[0045] Specifically, refer to Figure 4 As shown, the positioning column 30 includes a tapered column 31 and convex ribs 32. The column 31 is tapered with a cross section gradually decreasing from one end connected to the lampshade 10 to one end away from the lampshade 10. A plurality of convex ribs 32 are arranged at intervals along the outer circumference of the column 31. When the positioning column 30 is inserted into the positioning hole 21, the convex ribs 32 are elastically deformed, so that the positioning column 30 is clamped in the positioning hole 21.

[0046] In other embodiments, the positioning column 30 may be bonded to the positioning hole 21 to prevent the positioning column 30 from being separated from the positioning hole 21. Alternatively, other structures, such as a buckle structure, may be used to limit the connection seat 20.

[0047] In order to minimize the space occupied by the connection base 20 in the lampshade 10 , in some embodiments, a side of the connection base 20 facing the threading opening 121 abuts against the lampshade 10 .

[0048] For example, the threading opening 121 is provided on one side wall of the lampshade 10 in the longitudinal direction. Figure 2-Figure 4 As shown, in order to further reduce the difficulty of inserting the positioning column 30 into the positioning hole 21, the lamp also includes a baffle 50, two along the third direction ( Figure 1 The baffles 50 are symmetrically arranged at intervals (in the middle Y direction) on the opposite outer sides of the two positioning posts 30, and the spacing gradually decreases from the first end close to the threading opening 121 to the second end away from the threading opening 121. When the connecting seat 20 moves toward the positioning post 30 along the second direction, the baffles 50 guide the connecting seat 20, so that the connecting seat 20 can slide smoothly into the installation position of the positioning post 30. In addition, the second end of the baffle 50 can also serve as an auxiliary limiting structure for the terminal in the lampshade 10, reducing the difficulty of assembling the lamp. The first direction, the second direction and the third direction are perpendicular to each other.

[0049] Specifically, the baffle 50 and the lampshade 10 are also integrally injection molded, and the first end of the baffle 50 is connected to the lampshade 10 to increase the structural strength of the baffle 50 and reduce the possibility of deformation of the baffle 50 .

[0050] In order to reduce weight and cost while ensuring the structural strength of the connection base 20, refer to Figure 6 As shown, in some embodiments, a plurality of first weight reducing grooves 22 are arranged around the threaded hole 24 on the side of the connecting seat 20 facing away from the threading opening 121. The shapes of the first weight reducing grooves 22 may be the same or different, and are not specifically limited in the embodiments of the present utility model. However, it should be noted that the side of the first weight reducing grooves 22 facing the threaded hole 24 is arc-shaped and together form an annular structure. The thread is arranged on the inner wall of the annular structure to form the threaded hole 24. At this time, the groove wall shared by adjacent first weight reducing grooves 22 serves as a reinforcing rib, which can ensure the structural strength of the entire connecting seat 20, especially near the threaded hole 24, and the first weight reducing grooves 22 are arranged to avoid the positioning hole 21.

[0051] refer to Figure 7 As shown, in some embodiments, a plurality of second weight-reducing grooves 23 are disposed around the threaded hole 24 on one side of the connection seat 20 facing the threading opening 121 , and each second weight-reducing groove 23 has the same shape and is located on the end surface of the annular structure.

[0052] 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.

[0053] refer to Figure 8 and Fig. 9 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.

[0054] It is understandable that when wiring, the internal cable in the lampshade 10 needs to be led out from the lampshade 10, then connected to the external cable on the wiring connector, and then plugged back into the lampshade 10. Therefore, in some embodiments, the blind cover 40 is detachably connected to the internal cable. For example, a slot for inserting the internal cable is provided at one end of the blind 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 blind 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 blind cover 40, thereby passing through the lampshade 10.

[0055] 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.
