Technical Field

[0001] The utility model relates to the technical field of heat preservation, in particular to a telescopic heat preservation cover. Background Art

[0002] When the workpiece after heating treatment is transported between two devices, the problem of heat loss is easy to occur. In the prior art, a heat preservation tunnel is generally set on the conveying path of the workpiece after heating treatment to keep the workpiece after heating treatment warm through the heat preservation tunnel. The existing heat preservation tunnel is long and large in size, which is inconvenient to store and transport.

[0003] Among the existing patents, the Chinese patent document with application number 202320154742.4 discloses a retractable heat preservation cover device, including heat preservation cover 1 and heat preservation cover 2. Heat preservation cover 1 and heat preservation cover 2 are both inverted U-shaped structural parts. Heat preservation cover 1 and heat preservation cover 2 can be movably connected to the bracket of the conveying roller, and a conveying channel is formed between heat preservation cover 1, heat preservation cover 2 and the conveying roller; the height of heat preservation cover 1 is less than the height of heat preservation cover 2, and heat preservation cover 1 is installed on the inner side of heat preservation cover 2; heat preservation cover 1 is detachably connected to heat preservation cover 2 through a connecting assembly. Although heat preservation cover 1 and heat preservation cover 2 in this patent document can be telescopically slid, heat preservation cover 1 and heat preservation cover 2 need to release the connection state of the connecting assembly before they can be telescopically operated, which is inconvenient to use.

[0004] Therefore, the defects are very obvious and a solution is urgently needed. Utility Model Content

The first telescopic thermal insulation cover plate is fixedly connected to the fixed seat, and the two ends of the remaining telescopic thermal insulation cover plates are respectively slidably connected to the two tracks. The telescopic thermal insulation cover plate is located on the inner side of the side sealing plates, and the side sealing plates block the tracks. Between two adjacent telescopic thermal insulation cover plates, a limiting sealing plate is downwardly arranged at the outer end of the telescopic thermal insulation cover plate of the upper layer, and a limiting contact plate is upwardly arranged at the inner end of the telescopic thermal insulation cover plate of the lower layer, and the limiting contact plate is used to contact with the limiting sealing plate.

[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0020] As Figure 1 and Figure 2 shown, a telescopic heat-insulating cover provided by the utility model includes a fixed seat 1, a plurality of telescopic heat-insulating cover plates 2 which are sequentially stacked and telescopically slidably connected, two tracks 3 which are parallel and spaced apart, and side seal plates 4 installed on the outer sides of the tracks 3. The first telescopic heat-insulating cover plate 2 is fixedly connected to the fixed seat 1, and both ends of the remaining telescopic heat-insulating cover plates 2 are slidably connected to the two tracks 3 respectively. The telescopic heat-insulating cover plates 2 are located inside the side seal plates 4, and the side seal plates 4 shield the tracks 3; between two adjacent telescopic heat-insulating cover plates 2, a limiting seal plate 5 is downwardly arranged at the outer end of the upper-layer telescopic heat-insulating cover plate 2, and a limiting abutting plate is upwardly arranged at the inner end of the lower-layer telescopic heat-insulating cover plate 2. The limiting abutting plate is used for abutting against the limiting seal plate 5, and a lifting ring 6 is arranged at the outer end of the telescopic heat-insulating cover plate 2; specifically, the cross section of the telescopic heat-insulating cover plate 2 is in a U shape or a C shape.

[0021] In this embodiment, the utility model is taken as an example of covering an operating mechanism. The operating mechanism is used to connect two devices. The operating mechanism conveys the workpieces after heat treatment of one device to another device. During the process of the operating mechanism conveying the heated workpieces, this telescopic heat-insulating cover keeps the heated workpieces warm. The fixed seat 1 is fixedly installed on the device. One telescopic heat-insulating cover plate 2 is fixed, and the remaining telescopic heat-insulating cover plates 2 can stretch or contract along the tracks 3 with respect to each other. When two adjacent telescopic heat-insulating cover plates 2 are stretched to the limit position, the limiting seal plate 5 on the upper-layer telescopic heat-insulating cover plate 2 abuts against the limiting abutting plate on the lower-layer telescopic heat-insulating cover plate 2; when two adjacent telescopic heat-insulating cover plates 2 are contracted to the limit position, the lifting ring 6 on the lower-layer telescopic heat-insulating cover plate 2 abuts against the limiting seal plate 5 on the upper-layer telescopic heat-insulating cover plate 2. When the internal structure of the operating mechanism needs to be maintained, only this utility model needs to be contracted, and there is no need to frequently disassemble and assemble this telescopic heat-insulating cover. In addition, the arrangement of the lifting ring 6 facilitates the hoisting or handling of the telescopic heat-insulating cover plate 2; the side seal plates 4 shield the sliding connection parts of the tracks 3 and the telescopic heat-insulating cover plates 2, with a beautiful appearance, preventing foreign matters such as dust from entering the gaps between the tracks 3 and the telescopic heat-insulating cover plates 2, and avoiding the phenomenon that the telescopic heat-insulating cover plates 2 are stuck. The utility model can not only keep warm, but also be used in a telescopic manner, and is convenient for use, storage and transportation, etc. It has a wide range of applications, good versatility, and is convenient for handling the telescopic heat-insulating cover plates 2.

[0022] In this embodiment, the telescopic heat-insulating cover plate 2 includes a high-temperature resistant heat-insulating layer and an outer shell. The high-temperature resistant heat-insulating layer is arranged inside the outer shell, and the high-temperature resistant heat-insulating layer is heat-insulating cotton. This structural design enables the telescopic heat-insulating cover plate 2 to have a good heat-insulating effect.

[0023] In this embodiment, the outer shell includes two galvanized steel plates, and the high-temperature resistant heat-insulating layer is clamped between the two galvanized steel plates. This structural design further improves the heat-insulating effect and has a long service life.

[0024] In this embodiment, the end of the telescopic heat-insulating cover plate 2 is rotatably connected with a pulley 7, and the top surface of the track 3 is provided with a cylindrical guide rail 8, and the pulley 7 is slidably connected with the cylindrical guide rail 8. This structural design makes the sliding of the telescopic heat-insulating cover plate 2 smooth and stable.

[0025] In this embodiment, a mounting plate 9 is installed on the bottom surface of the track 3. The mounting plate 9 is installed on the external structure to facilitate the installation and fixation of the track 3.

[0026] In this embodiment, the high temperature resistant heat-insulating layer and the two galvanized steel plates are riveted together via rivets. This structural design ensures that the high temperature resistant heat-insulating layer and the two galvanized steel plates are firmly connected.

[0027] All technical features in this embodiment can be freely combined according to actual needs.
