Description

Technical Field

[0001] The invention relates to the technical field of power lines, in particular to a power transmission structure of a hard track lamp. Background Art

[0002] Existing hard track lamps include a hard track and a sliding lamp base with a lamp slidably set on the hard track. A conductive strip is set in the track of the hard track. The sliding lamp base is slidably set in the track and obtains power from the conductive strip through a spring sheet in contact with the conductive strip. The conductive strip is connected to an external power cord to obtain power. With this structure, once the length of the hard track is determined, it is difficult to change. It is difficult to obtain a hard track with a required length by cutting profiles according to site needs. Moreover, an external power cord is required, which is inconvenient to use. It is not possible to set various forms of light sources to obtain light sources of various properties. Summary of the invention

[0003] The object of the present invention is to provide a power transmission structure for hard track lamps that can overcome one or more of the above-mentioned shortcomings, can quickly and easily obtain hard rails of required lengths by cutting profiles according to on-site needs, and can be equipped with other forms of light sources.

[0004] The present invention is implemented as follows: it includes a U-shaped hard rail profile, a quick-connect cable, and a sliding base. The quick-connect cable includes an insulator and two or more wires arranged side by side on the insulator. The quick-connect cable is a built-in quick-connect cable in which all the wires are buried in the insulator, or the quick-connect cable is an exposed quick-connect cable in which part of the wires are exposed. A quick-connect cable embedding groove is provided at the bottom of the U-shaped recess of the U-shaped hard rail profile, and positioning grooves are provided on both inner side walls of the U-shaped recess of the U-shaped hard rail profile. The sliding base is slidably arranged in the U-shaped recess and is positioned by a hook structure on the sliding base positioned on the positioning groove. A guide hole directly reaching the quick-connect cable is provided on the sliding base, and a conductive quick connector is provided in the guide hole. The conductive quick connector includes an embedding component with a positioning clamp and a conductive head arranged on the embedding component. The conductive head of the conductive quick connector embedded in the guide hole rests on the wire of the quick-connect cable so that the wire of the quick-connect cable is connected to the power facilities or wires on the sliding base.

[0005] When in use, the U-shaped hard rail profile is cut according to the required length, and the quick-connect cable is embedded in the quick-connect cable embedding groove. Of course, the quick-connect cable is also cut according to the required length. The sliding base is set on the U-shaped recess, and then moved to the required position of the U-shaped hard rail profile. The position of the sliding base is fixed by the hook structure, and the conductive quick connector is inserted into the guide hole to make the conductive head contact with the wire of the quick-connect cable (if the quick-connect cable is a built-in quick-connect cable, the conductive head is a needle-pierced conductor, which is connected to the wire in the insulator after being inserted into the insulator. If the quick-connect cable is an exposed quick-connect cable, the conductive head is a blunt conductive head, and the wide contact surface of the conductive head is close to the exposed wire), and power is supplied to the electrical facilities (such as electric light sources) or wires on the sliding base through the quick-connect cable; at the same time, the quick-connect cable outside the U-shaped hard rail profile can be connected to the electrical facilities (such as electric light sources) by quick connection, which enriches the variety of light sources and the diversity of lights, and facilitates the user's light source setting and use.

[0006] Preferably, a pair of wire buckles are provided, which include inlays with positioning clips, and the two ends of a section of quick-connect cable in the U-shaped hard rail profile are positioned in the U-shaped hard rail profile through the pair of wire buckles, so that the quick-connect cable with a length much longer than the straight-line distance between the pair of wire buckles falls and is exposed outside the U-shaped hard rail profile. Electrical facilities with quick-connect structures can be quickly connected to the quick-connect cable that has fallen and is exposed outside the U-shaped hard rail profile, thereby enriching the application scenarios and lighting design.

[0007] Preferably, one end of the embedded component of the conductive quick connector is hinged to one side of the guide hole through an axis rotation, and the other end of the embedded component of the conductive quick connector is fixed to the other side of the guide hole. When in use, the embedded component is pressed toward the guide hole, so that the embedded component swings along the axis into the guide hole, so that the conductive head on the embedded component is close to the quick-connect cable, so that the conductive head is in close contact with the wire on the quick-connect cable. When the embedded component is completely inserted into the guide hole, the other end of the embedded component can be fixed to the buckle on the other side of the guide hole by a hook, so that the conductive quick connector is positioned in the guide hole.

[0008] Preferably, a sealing member is provided at the end of the U-shaped hard rail profile, and the sealing member includes a decorative head and an inlay block inlaid in the U-shaped recess of the U-shaped hard rail profile, and a hook structure is provided on the inlay block, and the sealing member is positioned and fixed at the end of the U-shaped hard rail profile through the hook structure, and a cable inlay recess is provided at the bottom of the decorative head, and the quick-connect cable led out from the end of the U-shaped hard rail profile is led out from the outside of the decorative head through the cable inlay recess.

[0012] The power transmission structure of the hard track lamp of the present invention is now described in further detail in conjunction with the accompanying drawings and embodiments: like Figure 1 As shown, the power transmission structure of the hard track lamp of the present invention is implemented as follows, including a U-shaped hard track profile 1, a quick-connect cable 2, and a sliding base 4 with an electric light source 3. The U-shaped hard track profile 1 is made of metal (such as aluminum alloy) or hard plastic, and the quick-connect cable 2 includes an insulator 201 and two or more wires 202 arranged side by side on the insulator 201. Figure 4 As shown, the quick-connect cable 2 is a built-in quick-connect cable in which the conductors 202 are all buried in the insulator 201, or Figure 5 The quick-connect cable 2 shown is an exposed quick-connect cable with a conductor 202 partially exposed. A quick-connect cable embedding groove 102 is provided at the bottom of the U-shaped recess 101 of the U-shaped hard rail profile 1, and positioning grooves 103 are provided on the two inner side walls of the U-shaped recess 101 of the U-shaped hard rail profile 1. The sliding base 4 is slidably set in the U-shaped recess 101 and is positioned by a first hook structure 5 on the sliding base 4 positioned on the positioning groove 103. The sliding base 4 is provided with a guide hole 6 directly reaching the quick-connect cable 2, and a conductive quick connector 7 is provided in the guide hole 6. The conductive quick connector 7 includes an embedding component 702 with a hook 701 and a conductive head 703 arranged on the embedding component 702. The conductive head 703 of the conductive quick connector 7 embedded in the guide hole 6 rests on the conductor 202 of the quick-connect cable 2 to make the conductor 202 of the quick-connect cable 2 conductive with the electric light source 3.

[0013] Preferably, one end of the embedded component 702 of the conductive quick connector 7 is rotatably hinged to one side of the guide hole 6 through a shaft 704 , and the other end of the embedded component 702 of the conductive quick connector 7 is fixed to the other side of the guide hole 6 through a positioning clamp 701 .

[0014] Preferably, a hook 701 with elasticity is connected to the side of the inlay component 702, a spring sheet 705 is arranged on the inner wall of the guide hole 6 corresponding to the hook 701, and an inclined surface 706 obliquely facing outwards is arranged on the upper part of the hook.

[0015] When in use, the embedded component 702 is pressed toward the guide hole 6, so that the embedded component 702 swings along the axis 704 into the guide hole 6, so that the conductive head 703 on the embedded component 702 is close to the quick-connect cable 2, so that the conductive head 703 is in close contact with the wire 202 on the quick-connect cable 2. When the embedded component 702 is completely inserted into the guide hole 6, the hook head of the positioning clamp 701 on the embedded component 702 is hooked at the bottom end of the spring piece 705, so that the conductive quick connector 7 is positioned in the guide hole 6; the embedded component 702 is pressed, and the upper part of the spring piece 705 moves to the upper part of the positioning clamp 701. On the inclined surface 706, under the action of the inclined surface 706, the spring piece 705 and the positioning clamp 701 serving as a hook are relatively separated, the hook head of the positioning clamp 701 serving as a hook leaves the bottom end of the spring piece 705, and the pressed embedded component 702 is released. Under the action of elasticity, the spring piece 705 moves downward relative to the inclined surface 706, so that the hook head of the positioning clamp 701 serving as a hook is located at the side of the spring piece 705 and is free from the constraint of the bottom of the spring piece 705. The embedded component 702 can swing upward and leave the guide hole 6.

[0017] Preferably, the hook structure 5 includes a rotating head 501 and wings 502 arranged on both sides of the rotating head 501. The rotating heads 501 of the first and second hook structures 5 are rotatably set on the inlay block 802 or the sliding base 4. The inlay block 802 or the sliding base 4 is provided with windows 503 matching the wings 502 on the two side walls facing the U-shaped hard rail profile 1, so that the inlay block 802 is driven by the rotating head 501 to rotate out of the window 503 and be clamped on the positioning groove 103, or rotate into the inlay block 802 or the sliding base 4 to break away from the constraint and fixation of the positioning groove 103.

The insulator 201 is then connected to the wire 202 in the insulator 201. If the quick-connect cable 2 is an exposed quick-connect cable, the conductive head 703 is a blunt conductive head, and the wide contact surface of the conductive head 703 is close to the exposed wire 202). The electric light source 3 on the sliding lamp base 4 is powered by the quick-connect cable 2 to light the electric light source; at the same time, the quick-connect cable 2 outside the U-shaped hard rail profile 1 can be connected to the quick-connect electric light source 9 by quick connection, which enriches the variety of light sources and the diversity of lights, and facilitates the user's light source setting and use.

Through a pair of wire clips 10, the two ends of a section of quick-connect cable 2 in the U-shaped hard rail profile 1 are positioned inside the U-shaped hard rail profile 1, so that the quick-connect cable 2, which is much longer than the straight-line distance between the pair of wire clips 10, falls and is exposed outside the U-shaped hard rail profile 1. The electrical facilities 11 (electric light source) with a quick-connect structure can be quickly connected to the quick-connect cable 2 that has fallen and is exposed outside the U-shaped hard rail profile 1, thereby enriching the application scenarios and lighting design.
