Two sliding grooves are opened on the track connecting piece. When the left curtain and the right curtain approach each other, the left curtain and the right curtain can be misaligned through the two sliding grooves, so as to prevent light transmission.

[0003] In the utility model with the application number CN202120815798.0, it discloses a magnetic curtain track convenient for opening and closing, including a track housing with a through groove penetrating through both ends. When the track is connected to the track housing, it is difficult to position the tracks at both ends, and there is a problem that the depths of the tracks entering the through groove are different. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a track connecting piece for increasing the positioning connection of the track.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A track connecting piece includes a connecting body and a cover plate. The connecting body and the cover plate are detachably connected. Positioning sections are formed at both ends of the connecting body, and positioning grooves are formed in the positioning sections. A misalignment cavity is formed between the cover plate and the connecting body. Both of the positioning grooves communicate with the misalignment cavity, and a limiting plate is formed between the misalignment cavity and the positioning grooves.

[0006] As a further improvement of the utility model, fixing holes are opened at the top of the positioning section.

[0007] As a further improvement of the utility model, a first support pillar is integrally formed in the connecting body. A first threaded hole is opened on the first support pillar, and a first connection hole corresponding to the first threaded hole is opened on the cover plate.

Detailed implementation mode

[0023] The following further details the present utility model in conjunction with the drawings and embodiments. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0024] Refer to Figures 1 to 6 As shown, a track connector in this embodiment includes a connecting body 1 and a cover plate 2. The connecting body 1 and the cover plate 2 are detachably connected. Among them, the cover plate 2 and the connecting body 1 can be connected by a buckle or by a bolt. Preferably, the detachable connection is achieved by a bolt;

[0025] Positioning sections 3 are formed at both ends of the connecting body 1. A positioning groove 31 is formed in the positioning section 3 for adapting to a track. Two tracks are respectively inserted into and fixed to the corresponding positioning grooves 31; an offset cavity 11 is formed between the cover plate 2 and the connecting body 1. Two symmetrically arranged slideways are provided in the connecting body 1. The two slideways are symmetric about the center of the line connecting the two positioning sections 3. Both slideways are used to connect pulleys, so that the left curtain and the right curtain can move in a set direction;

[0026] Both of the two positioning grooves 31 communicate with the offset cavity 11. A limiting plate 4 is formed between the offset cavity 11 and the positioning groove 31. The limiting plate 4 limits the track. When one end of the track is inserted into the corresponding positioning groove 31, its end facing the offset cavity 11 will abut against the limiting plate 4, thereby forming a limit on the track, so that after the two tracks are installed with the connecting body 1, the depths of the tracks extending into the positioning section 3 are the same, and the distances that the left curtain and the right curtain can move along the tracks are the same.

[0027] Fixing holes 32 are formed at the tops of the positioning sections 3. Screws are used to connect the positioning sections 3 and the tracks. The screws pass through the fixing holes 32 and are screwed into the tracks, thereby realizing the fixed connection between the tracks and the positioning sections 3.

[0028] Refer to Figure 5 and Figure 6As shown, in this embodiment, a first support column 12 is integrally formed in the connecting body 1. A first threaded hole 121 is formed in the first support column 12, and a first connection hole 21 corresponding to the first threaded hole 121 is formed in the cover plate 2. The first connection hole 21 is formed on the column inside the cover plate 2 to increase the depth of the first connection hole 21. There is one first support column 12, and it is located in the middle of the dislocation cavity 11, between two slideways, reducing the use of bolts, and only one first connection hole 21 needs to be formed on the cover plate 2, making the processing of the cover plate 2 more convenient;

[0029] The first connection hole 21 and the first threaded hole 121 are detachably connected by a bolt;

[0030] Setting the first support column 12 in the middle of the dislocation cavity 11 can extend the end length of the slideway without obstruction.

[0031] A plurality of reinforcing ribs 122 are formed between the first support column 12 and the connecting body 1. The arrangement of the reinforcing ribs 122 increases the connection strength of the first support column 12 and prevents the first support column 12 from breaking.

[0032] At least one card slot 41 is formed in the limiting plate 4, and a card block 22 adapted to the card slot 41 is formed at the end of the cover plate 2. The cooperation of the card slot 41 and the card block 22 can position the cover plate 2, and can prevent the cover plate 2 from detaching from the connecting body 1 after the bolt between the first support column 12 and the cover plate 2 is removed.

[0033] In another embodiment, two mutually misaligned second support columns are integrally formed in the connecting body 1. Second threaded holes are formed in the second support columns, and second connection holes corresponding to the second threaded holes are formed in the cover plate 2. Among them, there are two second support columns, so there are two second threaded holes. The two second support columns are respectively located at the tail ends of the slideways. This connection method makes the cover plate 2 more stable.

[0034] Refer to Figure 6 As shown, two symmetrically arranged first limiting strips 13 are formed in the connecting body 1. Both ends of the first limiting strip 13 respectively extend to the corresponding positioning grooves 31. The first limiting strip 13 limits the pulley, so that the pulley will not shake during sliding and is more stable.

[0035] Refer to Figure 5 As shown, two symmetrically arranged second limiting strips 23 are formed in the cover plate 2. Both ends of the second limiting strip 23 respectively extend to the end of the cover plate 2. The second limiting strip 23 corresponds to the first limiting strip 13, and the second limiting strip 23 and the first limiting strip 13 act together to limit the pulley.

[0036] Two limiting sections 42 are formed on the limiting plate 4, and the limiting sections 42 are respectively against the corresponding second limiting strips 23. The limiting sections 42 are used to receive the second limiting strips 23 and the limiting members on the track, so that the pulley can smoothly move from the track to the connector 1.

[0037] Extension strips 24 are integrally formed on opposite sides of the cover plate 2, and the extension strips 24 are in contact with the inner wall of the dislocation cavity 11. The provision of the extension strips 24 can reduce the shaking of the cover plate 2 and increase the stability of the cover plate 2 when the cover plate 2 and the connector 1 are not connected by bolts.

[0038] Reference Figure 5 As shown, the bottom of the extension strip 24 can fit with the bottom wall of the offset cavity 11 in the connector 1, thereby preventing the cover plate 2 from being excessively pressed downward.

[0039] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
