Description

Locking device for flying wing carriage

Technical Field

The utility model relates to a locking device, in particular to all-wing aircraft carriage locking device.

Background

The winged vehicle is also called a winged vehicle, also called a double-wing vehicle, and is called a wing-opening type van-type transport vehicle, and two wings of a carriage of the winged vehicle can be unfolded and lifted by 270 degrees by being driven by a power unit, so that the winged vehicle is named. At present, most of locking devices of two-wing side plates of all flying wing carriages in the market mostly adopt manual lock catches, the manual lock catches often have the problems of time and labor waste or insecure locking and the like when in use, and are easy to open after collision and unsafe. Therefore, a locking device for a flying wing carriage, which is convenient to operate and safe and reliable, needs to be designed.

Disclosure of Invention

In view of the above problem, an object of the utility model is to provide a convenient operation and reliable all-wing aircraft carriage locking device of locking to solve current manual hasp and waste time and energy and the insecure problem of locking.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides a winged vehicle compartment locking device, includes flexible driver, pull rod, L type hasp and limiting plate, flexible driver fixed mounting in winged vehicle compartment bottom. The L-shaped lock catch comprises a rotating plate and a locking plate, wherein one side of the rotating plate is vertically overlapped with the locking plate, and the other side of the rotating plate is rotatably connected with the bottom of the winged vehicle compartment through a rotating hinge. The bottom surface of rotor plate sets firmly a bedplate perpendicularly, the bedplate on seted up a connecting hole, the one end of pull rod with flexible driver is connected, the other end with the connecting hole is articulated. The limiting plate is fixed at the bottom of the flying wing carriage, and a containing hole for the pull rod to pass through is formed in the limiting plate.

Furthermore, the telescopic driver is fixed at the bottom of the flying wing carriage through a driver fixing frame.

Furthermore, the telescopic driver is an air cylinder or a hydraulic oil cylinder, and one end of the pull rod is hinged with the tail end of a telescopic rod of the telescopic air cylinder or the hydraulic oil cylinder.

The utility model discloses following beneficial effect has: the utility model provides a winged vehicle carriage locking device drives the pull rod motion through cylinder or hydraulic cylinder, and then drives the opening and shutting of L type hasp, realizes locking and opening the winged vehicle carriage, the utility model has the advantages of simple and reasonable structure, locking is reliable, and is safe convenient, and the practicality is high, convenient operation.

Fig. 2 is a schematic view of the wing plate opening state of the winged plate in the winged vehicle compartment of the present invention.

Description of the main component symbols: 1. a telescopic cylinder; 2. a cylinder fixing frame; 3. a pull rod; 4. l-shaped lock catches; 40. a support plate; 400. connecting holes; 41. a rotating plate; 42. a locking plate; 5. a hinge; 6. a wing plate.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 and 2, the locking device for the flying wing compartment comprises a telescopic cylinder 1, a cylinder fixing frame 2, a pull rod 3 and an L-shaped lock catch 4, wherein the cylinder fixing frame 2 is fixedly installed at the bottom of the flying wing compartment, the telescopic cylinder 1 is fixed on the cylinder fixing frame 2, and a control switch of the telescopic cylinder 1 is arranged in a cab. The L-shaped lock catch 4 comprises a rotating plate 41 and a locking plate 42, wherein one side of the rotating plate 41 is vertically overlapped with the locking plate 42, and the other side of the rotating plate 41 is connected with the bottom of the winged vehicle compartment through a rotating hinge 5. A support plate 40 is vertically and fixedly arranged on the bottom surface of the rotating plate 41, a connecting hole 400 is formed in the support plate 40, one end of the pull rod 3 is connected with the telescopic rod of the telescopic cylinder 1, and the other end of the pull rod is hinged with the connecting hole 400.

A limiting plate 7 is fixedly arranged at the bottom of the winged vehicle compartment, a containing hole 70 for the pull rod 3 to pass through is formed in the limiting plate 7, and the section size of the containing hole 70 is larger than the diameter of the pull rod 3. The purpose of the cross-sectional dimension of the receiving bore 70 being larger than the diameter of the drawbar 3 is: when L type hasp 4 is opened, pull rod 3 can use the pin joint of pull rod 3 and telescopic cylinder 1 to rotate certain distance downwards as the centre of a circle, and when L type hasp 4 was closed, this accommodation hole 70 can continue to rotate downwards pull rod 3 and carry on spacingly to make telescopic cylinder 1 can promote pull rod 3 right, finally realize L type hasp and fasten pterygoid lamina 6 in all-wing aircraft carriage again.

The utility model discloses a theory of operation does: the locking devices of the flying wing carriages are uniformly distributed along two sides of the length direction of the flying wing carriages, when the wing plates 6 of the flying wing carriages need to be opened, a control switch is pressed down in a cab, the telescopic cylinder 1 acts to drive the pull rod 4 to pull the support plate 40, so that the L-shaped lock catches 4 of the locking devices of the flying wing carriages are opened simultaneously, and the wing plates 6 of the flying wing carriages can be opened; after the wing plate 6 of the all-wing aircraft carriage is closed, the control switch is pressed down again, the telescopic cylinder 1 drives the pull rod 4 to push the support plate 40, and then the L-shaped lock catches 4 of the all-wing aircraft carriage locking devices are reset simultaneously to lock the wing plate 6 of the all-wing aircraft carriage.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
