Description

Technical Field

[0001] This utility model relates to the field of chassis technology, and in particular to a split chassis structure. Background Technology

[0002] During ship navigation and operations, key areas such as the bridge, control room, and engine room require centralized management and control of ship power, navigation, communication, and safety monitoring systems through various control devices. Among these, the split-type chassis structure has become an important component of the ship's control system due to its space-saving design and flexible installation (adapting to ship bulkhead structures), and is widely used in scenarios such as video surveillance switching, equipment status adjustment, and signal command transmission.

[0003] When installing equipment in existing enclosures, the limited internal space severely restricts the movement of personnel, making it difficult to extend arms and hands flexibly. This results in clumsy and inaccurate installation movements. For example, when tightening bolts to secure equipment, the confined space may prevent the application of force, requiring repeated adjustments to posture and significantly extending installation time. Furthermore, the complex and variable swaying of ships during navigation means that if equipment inside the enclosure is not securely fixed, it will frequently collide or rub against the enclosure walls and other equipment.

[0004] Therefore, it is necessary to provide a new split-type chassis structure to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a split chassis structure.

The extension shaft ends of the two telescopic cylinders are connected to one end of the two push-pull rods, and the other ends of the two push-pull rods are fixedly connected to the two fixed plates. A sliding assembly is provided between the placement platform and the extended rectangular plate.

[0008] Preferably, the sliding assembly includes two limiting sliders and two limiting grooves. The two limiting sliders are fixedly connected to both ends of the lower surface of the placement platform away from the fixed plate. The two limiting grooves are opened on both ends of the upper surface of the extended plate. The two limiting sliders are slidably connected inside the two limiting sliders.

[0009] Preferably, the equipment fixing assembly includes a gear transmission assembly, two sliding guide rails, two sliding frame plates, and two fixed clamping plates. The two sliding guide rails are respectively arranged on both sides of the upper surface of the placement platform, and the two sliding frame plates are slidably connected between the two sliding guide rails. The upper surface of the two sliding frame plates is fixedly connected to the two fixed clamping plates respectively, and a gear transmission assembly is provided between the placement platform and the two sliding frame plates.

[0010] Preferably, the gear transmission assembly includes a drive motor, a drive motor shaft, a drive gear, and two transmission racks.

[0011] Preferably, the power supply and the fan are at the same level.

[0012] Compared with related technologies, the split chassis structure provided by this utility model has the following advantages:

[0013] The placement platform uses a placement plate to guide the control equipment into the housing, allowing workers to install the equipment without needing to use any part of their body inside the chassis. This eliminates the limitations of the internal space, allowing for flexible extension of arms and hands, improving operational accuracy, and shortening installation time. Two fixing plates clamp and secure the control equipment, ensuring stable operation even during complex and varied swaying of the ship, preventing frequent collisions or friction between the control equipment and the chassis walls or other equipment.

[0022] In the specific implementation process, such as Figure 1-4 As shown, the device includes a housing 1, an insert box 2 inside the housing 1, an extension plate 3 fixedly connected to the bottom of the insert box 2, a placement platform 301 slidably connected to the extension plate 3, an extension sliding assembly between the extension plate 3 and the placement platform 301, a device placement plate 4 fixedly connected to the upper surface of the placement platform 301, a control device placed on the device placement plate 4, a device fixing assembly on the placement platform 301, a reset switch 201 on the side of the insert box 2 near the opening of the housing 1, two fan fixing plates 202 on both sides of the insert box 2, two fans 203 on the side of the two fan fixing plates 202 close to each other, and a power supply 5 inside the insert box 2.

[0023] In the specific implementation process, such as Figure 2-3As shown, the extended sliding assembly includes a sliding component, two telescopic cylinders 7, two push-pull rods 701, and two fixing plates 702. The two fixing plates 702 are fixedly connected to both ends of the lower surface of the placement platform 301. The two telescopic cylinders 7 are fixedly connected to both ends of one side of the extended rectangular plate 3. The extension shaft ends of the two telescopic cylinders 7 are connected to one end of the two push-pull rods 701, and the other ends of the two push-pull rods 701 are fixedly connected to the two fixing plates 702. A sliding assembly is provided between the placement platform 301 and the extended rectangular plate 3. The sliding assembly includes two limiting sliders 306 and two limiting grooves 305. The two limiting sliders 306 are fixedly connected to both ends of the lower surface of the placement platform 301 on the side away from the fixing plates 702. The two limiting grooves 305 are formed on both end faces of the upper surface of the extended rectangular plate 3. The two limiting sliders 306 are slidably connected inside the two limiting sliders 306.

[0024] In the specific implementation process, such as Figure 4 As shown, the equipment fixing assembly includes a gear transmission assembly, two sliding guide rails 304, two sliding frame plates 302, and two fixed clamping plates 303. The two sliding guide rails 304 are respectively disposed on both sides of the upper surface of the placement platform 301. The two sliding frame plates 302 are slidably connected between the two sliding guide rails 304. The two fixed clamping plates 303 are respectively fixedly connected to the upper surfaces of the two sliding frame plates 302. A gear transmission assembly is provided between the placement platform 301 and the two sliding frame plates 302. The gear transmission assembly includes a drive motor 603 and a drive... The motor shaft 601, drive gear 6, and two transmission rack plates 602 are arranged. The drive motor 603 is located at the center of the lower surface of the placement platform 301. The output end of the drive motor 603 is connected to one end of the drive motor shaft 601, and the other end of the drive motor shaft 601 is fixedly connected to the drive gear 6. The two transmission rack plates 602 are respectively located on the lower surface of the two sliding frame plates 302. The two transmission rack plates 602 are staggered and mesh with the drive gear 6. Preferably, the power supply 5 and the fan 203 are at the same level.

[0025] The working principle of this utility model is as follows: Two telescopic cylinders 7 are activated to drive two push-pull rods 701 to push two fixed plates 702 to the outside of the housing 1. Simultaneously, the two fixed plates 702 drive the placement platform 301 to move stably outward under the auxiliary limiting of its two limiting sliders 306 and two limiting grooves 305. Then, the placement platform 301 drives the equipment placement plate 4 to move synchronously. The operator then installs the control device on the upper surface of the equipment placement plate 4. Then, the two telescopic cylinders 7 are activated in the reverse direction to drive the two push-pull rods 701 to pull the two fixed plates 702 to the inside of the housing 1. The above operation is then repeated in the reverse direction, allowing the placement platform 301 to drive the control device into the housing 1 through the equipment placement plate 4. This allows the operator to install the equipment without needing to enter the housing, without being restricted by the internal space of the housing. Arms, hands, and other operating parts can be flexibly extended, improving operational accuracy and shortening installation time.

[0026] After the control equipment is installed, the drive motor 603 is started to drive the drive motor shaft 601 to rotate the drive gear 6. The drive gear 6 meshes and drives the two transmission rack plates 602 to move closer to each other. Then, the two transmission rack plates 602 drive the two sliding frame plates 302 to move closer to each other on the two sliding guide rails 304. Thus, the two sliding frame plates 302 drive the two fixed clamping plates 303 to clamp and fix the control equipment. As a result, during the ship's navigation, the direction and amplitude of the swaying are complex and changeable. The control equipment inside the chassis will not frequently collide or rub against the inner wall of the chassis or other equipment, ensuring the stable operation of the control equipment.

[0027] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
