Description

Technical Field

[0001] This utility model relates to the field of fixed structures, and in particular to a fixed structure for a helicopter detector. Background Technology

[0002] With the development of technology, the internal chassis of helicopters has gradually become lighter and smaller. The helicopter chassis is equipped with the required detectors according to the functional needs, and the helicopter chassis and the bracket are connected by plug-in method.

[0003] During the process of plugging and unplugging the chassis and bracket, when the chassis and bracket are pulled out to a certain distance, the chassis is shaken up and down from the rear to detach it. However, the ceramic pins on the plug end and the ceramic pins on the socket end have already detached, but the ceramic pins on the plug end are near the opening of the ceramic sleeve. During the shaking process, due to the manual operation of the staff, the socket shell and the plug shell will be misaligned to a certain extent, and the ceramic sleeve may be damaged due to improper force.

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

[0005] To solve the above-mentioned technical problems, this utility model provides a helicopter detector fixing structure.

[0006] The helicopter detector fixing structure provided by this utility model includes a chassis and a bracket. The chassis and the bracket are plugged in and connected. The front end of the chassis extends downward and has a guide hole. A guide post is fixedly connected to the end of the bracket. The guide post can be movably inserted into the guide hole. A placement groove is opened at the end of the guide post. A pressing device is set in the placement groove. Multiple movable grooves are opened around the side wall of the guide post. A spring is fixedly connected in the movable groove. A positioning block is also movably set in the movable groove. The end of the spring is fixedly connected to the positioning block. The end of the positioning block away from the bracket is set as an inclined surface. The pressing device can drive multiple positioning blocks to move into the movable groove.

[0007] Preferably, the extrusion device includes a pulling member, multiple pull rods, and multiple transmission blocks. The multiple pull rods are respectively fixedly connected to multiple positioning blocks, with one end of each pull rod extending into the placement groove. The multiple transmission blocks are respectively fixedly connected to the multiple pull rods, with the end of each transmission block away from the pull rod being an inclined surface. The pulling member can extrude the inclined surfaces of the multiple transmission blocks, causing the multiple transmission blocks to move closer to each other.

[0008] Preferably, the pulling component includes a connecting rod, a bearing plate, a compression spring, and multiple pressing blocks. One end of the connecting rod is fixedly connected to the bearing plate, and the other end of the connecting rod extends into a placement groove. The multiple pressing blocks are all fixedly installed on the bearing plate. One end of each pressing block is an inclined surface, and the inclined surfaces of the multiple pressing blocks are respectively set to correspond to the inclined surfaces of the multiple transmission blocks. The two ends of the compression spring are respectively fixedly connected to the bottom wall of the placement groove cavity and the bearing plate.

[0009] Preferably, guide blocks are fixedly connected to both sides of the bearing plate, and one end of the guide block is slidably disposed in a groove opened in the inner wall of the placement slot.

[0010] Preferably, a pull plate is fixedly connected to one end of the connecting rod extending out of the placement groove.

[0011] Preferably, the size of the guide post is adapted to the size of the guide hole.

[0012] Compared with related technologies, the helicopter detector fixing structure provided by this utility model has the following beneficial effects:

[0013] 1. In the process of pulling out, the guide post and guide hole of this utility model prevent large-angle displacement during manual pulling out by workers, thus providing a certain degree of protection for the connected parts.

[0014] 2. In this utility model, the movement of the chassis involves the guide hole pressing against the inclined surfaces of multiple positioning blocks, causing the positioning blocks to move into the movable groove. Once the positioning blocks have moved past the positioning blocks, the chassis and bracket are successfully connected. At this point, there is no need to continue pushing the chassis, thus providing a certain positioning function for the movement of the chassis.

[0015] 3. After the chassis and bracket are connected, multiple positioning blocks are located on one side of the guide hole, which also serves to limit the chassis, making the connection between the chassis and bracket less prone to loosening. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-4 ,in, Figure 1 A schematic diagram of the helicopter detector fixing structure provided by this utility model; Figure 2 for Figure 1 The diagram shown is a structural schematic of the chassis. Figure 3 for Figure 1 The diagram shows the structure of the bracket. Figure 4 for Figure 1 The diagram shows a cross-sectional view of the guide post.

[0023] In the specific implementation process, such as Figures 1-4 As shown, the device includes a chassis 1 and a bracket 2. The chassis 1 and the bracket 2 are pluggable. The chassis 1 extends downward at the front end and has a guide hole 3. The bracket 2 is fixedly connected to a guide post 4. The guide post 4 can be movably inserted into the guide hole 3. The size of the guide post 4 is adapted to the size of the guide hole 3. The guide post 4 has a placement groove 5 at its end. A pressing device is installed in the placement groove 5. Multiple movable grooves 6 are opened around the side wall of the guide post 4. A spring 7 is fixedly connected in the movable groove 6. A positioning block 8 is also movably installed in the movable groove 6. The end of the spring 7 is fixedly connected to the positioning block 8. The end of the positioning block 8 away from the bracket 2 is set as an inclined surface. The pressing device can drive multiple positioning blocks 8 to move into the movable groove 6. The chassis 1 moves on the bracket 2. The guide hole 3 presses the inclined surface of multiple positioning blocks 8, thereby causing the positioning blocks 8 to move into the movable groove 6. The positioning blocks 8 move safely into the movable groove 6. When the guide hole 3 on the chassis 1 moves past the positioning block 8, the chassis 1 and the bracket 2 are plugged in.

[0024] The extrusion device includes a pulling member, multiple pull rods 9, and multiple transmission blocks 10. The pull rods 9 are fixedly connected to multiple positioning blocks 8, with one end extending into the placement groove 5. The transmission blocks 10 are fixedly connected to the pull rods 9, with the end of each transmission block 10 away from the pull rod 9 being an inclined surface. The pulling member can extrude pressure on the inclined surfaces of the transmission blocks 10, causing them to move closer together. The pulling member includes a connecting rod 11, a bearing plate 12, a compression spring 13, and multiple extrusion blocks 14. One end of the connecting rod 11 is fixedly connected to the bearing plate 12, and the other end extends out of the placement groove 5. Multiple extrusion blocks 14 are fixedly installed on the support plate 12. One end of the extrusion block 14 is an inclined surface. The inclined surfaces of the multiple extrusion blocks 14 are respectively set to correspond to the inclined surfaces of the multiple transmission blocks 10. The two ends of the compression spring 13 are respectively fixedly connected to the bottom wall of the inner cavity of the placement groove 5 and the support plate 12. During the pulling process, the pull plate 16 is pulled, and the connecting rod 11 and the support plate 12 are moved through the pull plate 16. The multiple extrusion blocks 14 extrude multiple transmission blocks 10 through the inclined surfaces of the two. The positioning block 8 is moved into the movable groove 6 through the transmission block 10 and the pull rod 9, which facilitates the pulling out of the machine box 1.

[0025] Guide blocks 15 are fixedly connected to both sides of the support plate 12. One end of the guide block 15 is slidably disposed in the groove opened in the inner wall of the placement groove 5. The stability of the support plate 12 when moving is improved by the guide blocks 15.

[0026] A pull plate 16 is fixedly connected to one end of the connecting rod 11 that extends out of the placement groove 5. The pull plate 16 facilitates the pulling of the connecting rod 11.

[0027] The working principle of this utility model is as follows: When the chassis 1 is pushed onto the bracket 2, the guide hole 3 at the front end of the chassis 1 will first contact the guide post 4 of the bracket 2 and move in this direction. As the chassis 1 moves, the guide hole 3 presses against the inclined surfaces of multiple positioning blocks 8, thereby causing the positioning blocks 8 to move into the movable groove 6. The positioning blocks 8 are safely moved into the movable groove 6. After the guide hole 3 on the chassis 1 has moved past the positioning blocks 8, the chassis 1 and the bracket 2 are connected. Under the action of the compressed spring 7, the positioning blocks 8 are reset. The multiple positioning blocks 8 are located on one side of the guide hole 3, which also serves as a limit for the chassis 1, so that the chassis 1 and the bracket 2 are connected. The connector is not easy to loosen. During the pulling process, the pull plate 16 is pulled, which drives the connecting rod 11 and the bearing plate 12 to move. Multiple pressing blocks 14 press multiple transmission blocks 10 through their inclined surfaces. The transmission blocks 10 and the pull rod 9 drive the positioning block 8 to move into the movable groove 6. The spring 7 is compressed and the compression spring 13 is stretched, pulling the housing 1 so that the housing 1 moves past the positioning block 8. Under the action of the spring 7 and the compression spring 13, each component is reset. Through the guide post 4 and the guide hole 3, the operator is less likely to have a large angle of displacement during the manual pulling process, thus playing a certain protective role for the connected components.

[0028] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
