Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a telescopic device for cable trays and the cable tray thereof. Background Technology

[0002] In the field of cable trays, trough-type cable trays are trough-shaped components made from a single sheet of steel. The difference between them and tray-type cable trays is the height-to-width ratio. Tray-type cable trays are shallow and wide, while trough-type cable trays have a certain depth and enclosure.

[0003] Currently, the lengths of these trough-type cable trays are all of fixed specifications in the market. In actual construction, multiple trough-type cable trays are usually spliced ​​together for use. However, the joints between the cable trays can only be connected and limited, and cannot be extended or adjusted, thus restricting the flexibility of the trough-type cable trays during use.

[0007] Preferably, the mounting part includes a placement groove, which is formed on the side of the sliding plate. The side of the sliding plate also has a through hole, which is located above the placement groove. A fan-shaped groove is formed at the end of the through hole away from the placement groove. The fan-shaped groove communicates with the through hole. A portion of the abutment component is inserted into the through hole, and the abutment component is partially operably moved into the placement groove.

[0008] Preferably, the limiting component includes a plurality of limiting teeth, the limiting teeth being linearly arrayed and installed below the rectangular mounting hole, and the top of the limiting teeth and the top wall of the rectangular mounting hole having reserved placement space for accommodating the abutment component.

[0009] Preferably, the abutting assembly includes a connecting shaft rotatably mounted in the through hole. A knob is mounted on one end of the connecting shaft, and an abutting plate is mounted on the end of the knob near the connecting shaft. The abutting plate is disposed in the fan-shaped groove. A pawl is mounted on the other end of the connecting shaft. The pawl operably abuts against the limiting tooth. A spring is sleeved on the connecting shaft. One end of the spring abuts against the inner wall of the placement groove, and the other end of the spring abuts against the side wall of the pawl.

[0010] A telescopic cable tray includes a cable tray body, which is U-shaped. The sidewall of the cable tray body is the aforementioned connecting plate.

[0011] Beneficial Effects: This utility model relates to a telescopic device for cable trays and the cable tray itself. When it is necessary to splice the cable tray bodies together, the connector is inserted into the end of the cable tray body. When the connector is inserted, an external force is applied to the knob to compress the spring, causing the abutment component to move into the placement groove. This allows the connector to be smoothly inserted into the cable tray. After the connector is inserted into the cable tray body, the abutment component moves into the rectangular mounting hole under the action of the spring. By using the abutment component and the limiting component to limit each other, the cable tray body and the connector can be mutually inserted and limited. Under the action of the abutment component, the position of the connector in the cable tray body can be adjusted to achieve retraction. This can prevent the cable tray body from swinging when connected to the connector, and can also adjust the spacing at the connection of the cable tray bodies, making the connection of the cable tray bodies flexible.

[0014] like Figures 1 to 8This utility model provides a technical solution: a telescopic device for cable trays, including a connecting plate 1. A rectangular mounting hole 2 is provided below the connecting plate 1. A limiting component 3 is installed on the bottom inner wall of the mounting hole. The limiting component 3 includes a plurality of limiting teeth 31, which are linearly arrayed below the rectangular mounting hole 2. A placement space 32 is reserved between the top of the limiting teeth 31 and the top wall of the rectangular mounting hole 2. The placement space 32 is used to accommodate an abutment component 6. A sliding plate 4 is installed on the side of the connecting plate 1. The sliding plate 4 is slidably connected to the connecting plate 1. An installation part 5 is provided on the sliding plate 4 near the corresponding position of the rectangular mounting hole 2. The installation part 5 includes a placement groove 51, which is provided on the side of the sliding plate 4. A through hole 52 is also provided on the side of the sliding plate 4. The through hole 52 is located above the placement groove 51 and away from the placement groove 51. A fan-shaped groove 53 is provided at one end of the abutment, which communicates with the through hole 52. The abutment assembly 6 includes a connecting shaft 61, which is rotatably mounted in the through hole 52. A knob 62 is installed at one end of the connecting shaft 61, and an abutment plate 63 is installed at the end of the knob 62 near the connecting shaft 61. The abutment plate 63 is disposed in the fan-shaped groove 53. A pawl 64 is installed at the other end of the connecting shaft 61, and the pawl 64 operably abuts against the limiting tooth 3. On the 1st, a spring 65 is sleeved on the connecting shaft 61. One end of the spring 65 abuts against the inner wall of the placement groove 51, and the other end of the spring 65 abuts against the side wall of the pawl 64. That is, when an external force is applied to the knob 62, the spring 65 is compressed, which moves the pawl 64 into the placement space 32. After the knob 62 is released, the pawl 64 is inserted into the rectangular mounting hole 2, so that the pawl 64 and the limiting tooth 31 abut against each other and limit each other, thus realizing the mutual splicing and limiting of the connecting plate 1 and the sliding plate 4.

[0015] In a further embodiment, a guide block 7 is installed on the side of the connecting plate 1. The guide block 7 is installed along the length direction of the connecting plate 1. A sliding groove 8 is provided on the side wall of the sliding plate 4. The guide block 7 is slidably installed in the sliding groove 8. With the cooperation of the guide block 7 and the sliding groove 8, the sliding plate 4 slides on the side of the connecting plate 1, so that when the sliding plate 4 is inserted into the connecting plate 1, it avoids the situation of swinging after connection.

[0016] A telescopic cable tray includes a cable tray body 9, which is U-shaped. The sidewall of the cable tray body 9 is the aforementioned connecting plate 1. The top of the cable tray body 9 has a plurality of threaded holes 10, which are arranged linearly along the length of the cable tray. An abutment component 6 is installed at one end of the cable tray. The abutment component 6 is the aforementioned abutment component 6. A connector is inserted into the cable tray. The connector is U-shaped, and the sidewall of the connector is the aforementioned sliding plate.

[0017] Through the above technical solution, the present invention can achieve the following working process: When it is necessary to splice the cable tray bodies 9 together, first insert the connector into the cable tray body 9, and at the same time apply external force to the knob 62 to compress the spring 65, so that the pawl 64 moves into the placement groove 51. When the rectangular mounting hole 2 in the connector moves into the placement groove 51, release the compression of the spring 65. Under the action of the spring 65, the pawl 64 moves into the rectangular mounting hole 2. The other end of the connector is installed with another set of cable tray bodies 9 in the same way. By applying external force to the cable tray body 9, the positional relationship between the connector and the cable tray can be adjusted to realize the spacing between the cable tray bodies 9. After the spacing is adjusted, the cable tray body 9 and the connector are mutually abutted and limited by the cooperation of the pawl 64 and the limiting tooth 31.

[0018] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments.
