[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-Figure 3 The utility model provides an embodiment: a tinned copper busbar cable bridge, comprising a sleeve 1, the top of the sleeve 1 is elastically connected to a connecting pipe 3 through a reset spring 2, the connecting pipe 3 can move vertically on the inner wall of the sleeve 1 with a wedge block 4, a limiting mechanism is arranged at the bottom end of the connecting pipe 3, a slot 5 is arranged on the side wall of the sleeve 1, a moving sleeve 6 is slidably connected to the inner wall of the sleeve 1, the sleeve 1 and the moving sleeve 6 are both made of tinned copper, a cable bridge is formed by the sleeve 1 and the moving sleeve 6, and a plug block 7 is fixedly connected to the side wall of the moving sleeve 6.

[0028] Reference Figure 4 The top inner wall of the movable sleeve 6 is elastically connected with a card block 10 through a positioning spring 9. The outer wall of the sleeve 1 is provided with a card slot 8, and the card slot 8 has a vertical opening and a horizontal opening. When the card block 10 coincides with the vertical opening of the card slot 8, the position of the movable sleeve 6 can be limited. When the card block 10 coincides with the horizontal opening of the card slot 8, the card block 10 can be allowed to move with the movable sleeve 6. The top inner wall of the movable sleeve 6 is fixedly connected to one end of the positioning spring 9. When the card block 10 moves upward, the positioning spring 9 will be compressed. When resetting, the elastic force of the positioning spring 9 is used to reset the card block 10. The other end of the positioning spring 9 is fixedly connected to the top of the card block 10. The card block 10 is slidably connected to the inner wall of the movable sleeve 6. A notch is provided on the movable sleeve 6, so that the card block 10 can slide along the notch of the movable sleeve 6, and the card block 10 is engaged with the inner wall of the card slot 8.

[0029] Reference Figure 1-Figure 3 The top end of the sleeve 1 is fixedly connected to one end of the return spring 2. When the connecting tube 3 moves upward, the return spring 2 will be stretched. When resetting, the elastic force of the return spring 2 is used to bring the connecting tube 3 back to normal state. The other end of the return spring 2 is fixedly connected to the inner side wall of the connecting tube 3. The connecting tube 3 passes through and is slidably connected to the inner wall of the sleeve 1. The limiting mechanism includes a wedge block 4, which is fixedly connected to the bottom end of the connecting tube 3. The plug block 7 is plugged into the inner wall of the slot 5. The middle part of the plug block 7 is clamped with the outer wall of the wedge block 4. The middle part of the plug block 7 has an opening, which allows the middle opening of the plug block 7 to be clamped with the wedge block 4.

[0030] Working principle: First, when you need to adjust the use length of the tinned copper busbar cable tray, you only need to move the block 10 upwards and compress the positioning spring 9 to separate the vertical opening of the block 10 and the slot 8, so that the horizontal openings of the block 10 and the slot 8 overlap, and let the block 10 extend outward along the inner wall of the sleeve 1 with the movable sleeve 6 to increase the use length of the tinned copper busbar cable tray. When limiting is required, you only need to loosen the block 10 and use the reverse elastic force of the positioning spring 9 to reset the block 10, so that the block 10 overlaps and engages with the vertical opening of the slot 8, limit the length of the entire movable sleeve 6 moved out, and adjust the use length of the tinned copper busbar cable tray according to actual needs.

[0031] When it is necessary to splice the two sets of sleeves 1 and the movable sleeve 6, it is only necessary to insert the plug block 7 on the side wall of the movable sleeve 6 into the slot 5, let the left end of the plug block 7 squeeze the inclined surface of the wedge block 4, let the wedge block 4 move the connecting pipe 3 upward and stretch the reset spring 2, when the wedge block 4 and the middle opening of the plug block 7 overlap, use the reverse elastic force of the reset spring 2 to reset the connecting pipe 3 and the wedge block 4, let the wedge block 4 and the middle opening of the plug block 7 be inserted and limited, and complete the assembly of the two sets of sleeves 1 and the movable sleeve 6.

[0032] When it is necessary to release the splicing of the sleeve 1 and the movable sleeve 6, it is only necessary to pull the connecting tube 3 upwards and stretch the return spring 2 to separate the middle opening of the wedge block 4 and the insert block 7, and remove the insert block 7 from the notch of the slot 5. It is simple and convenient during use.

[0033] When you need to adjust the length of the tinned copper busbar cable tray again, just follow the first step.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
