Description
Technical Field
The utility model belongs to the technical field of helicopter cabin cover supports and designs, especially, relate to a folding vaulting pole device.
Background
Some cabin covers on the helicopter need to be checked before and after each flight, and some cabin covers need to be turned upwards and fixed at a certain angle by using a supporting rod for supporting in order to facilitate work and maintenance. Therefore, the stay bars on helicopters are used frequently, and must have sufficient reliability and long life, and need to be simple, reliable, and durable.
As the supporting function of the cabin cover, the support rod is widely applied. Non-foldable straight rods or pneumatic support rods with pneumatic springs are generally adopted on helicopters and vehicles. The former needs enough space in the cabin, otherwise the stay bar can not be stored in the cabin when the cabin cover is closed, and the cabin structure and the cabin cover need to be respectively provided with a fixed support of the movable end of the stay bar for connection and conversion of two states, so that the installation requirement is high, and the operation is complicated when the cabin cover is opened and closed; the support rod has a certain telescopic function by adopting a pneumatic spring, but has the defects of high manufacturing cost and low reliability.
SUMMERY OF THE UTILITY MODEL
In view of the above, an object of the present invention is to provide a folding brace device for supporting a cabin cover, which has the advantages of low cost, reliability and durability, and is favorable for improving the maintainability of the upper cabin cover of a helicopter or a vehicle.
In order to achieve the above purpose, the utility model adopts the following technical scheme to realize.
A folding brace apparatus, comprising: the device comprises an upper stay bar, a sleeve, a movable block, a lower stay bar and a joint bearing;
the upper support rod and the lower support rod are movably connected through a movable block;
the sleeve is movably sleeved outside the upper support rod;
the joint bearing is installed at the bottom of the lower support rod.
The utility model discloses technical scheme's characteristics and further improvement do:
(1) when the cabin cover is supported by the folding support rod device, one end of the upper support rod is connected to a support of the cabin cover, and the lower support rod is connected to a support of the cabin structure through the joint bearing.
(2) The spherical plain bearing is used for rotating on a support of the cabin structure at different angles.
(3) When the folding support rod device is opened, the sleeve slides downwards from the upper support rod under the action of gravity, the upper support rod, the movable block and the lower support rod are fixed on the same axis, and the folding support rod device becomes a two-force straight rod.
(4) When the folding stay bar device is folded, the sliding sleeve is pushed upwards to the upper stay bar, and the folding stay bar is converted into a folding shape from a straight bar shape through the movable block.
(5) The device further comprises: and the two semicircular head rivets are respectively used for fixing the two ends of the movable block on the upper support rod and the lower support rod.
The utility model provides a pair of folding vaulting pole device can realize upwards opening the support vaulting pole of cabin cover on vehicle, helicopter, the aircraft. The support rod has the advantages of simple structure, low manufacturing cost, good operability, reliability and durability, and is beneficial to improving the use and maintenance of the upper cabin cover of the helicopter and the vehicle.
Drawings
Fig. 1 is a schematic structural diagram of a folding brace apparatus provided by an embodiment of the present invention, wherein 1 is an upper brace, 2 is a sleeve, 3 is a half-round rivet, 4 is a movable block, 5 is a lower brace, and 6 is a joint bearing.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Aiming at the upward opening cabin cover structure, a folding support rod component is developed and used for supporting and fixing the cabin cover in an upward opening state. The embodiment of the utility model provides a folding vaulting pole subassembly includes vaulting pole (1), sleeve pipe (2), half round head rivet (3), movable block (4), lower vaulting pole (5), joint bearing (6), as shown in fig. 1.
One end of the folding brace rod component is connected to the support of the cabin cover, and the other end of the folding brace rod component is connected to the support of the cabin structure. When the cabin cover is opened, the folding stay bar is straightened, the sleeve 2 slides downwards from the upper stay bar 1 under the action of gravity, the upper stay bar 1, the movable block 4 and the lower stay bar 5 are fixed on the same axis, and the stay bar assembly is changed into a two-force straight bar to keep the cabin cover at the opened position.
When closing the cabin cover, push the sleeve 2 to the upper stay bar 1 upwards, in addition hold the cabin cover and lower it with the hand, then the cabin cover moves downwards under the action of gravity, closes gradually, and the folding stay bar changes from the straight bar shape to the folding shape. After the cabin cover is closed, the folding support rod assembly is stored in the cabin.
The movable block 4 prevents the upper support rod 1 and the lower support rod 5 from being crossed and collided, and the joint bearing 6 plays a role in adjusting angles of the support rods in different states. The folding support rod assembly is simple in structure, and high reliability of the support rod is guaranteed. Compared with a common straight rod support rod, the middle folding function is added, the number of the supports on the cabin cover is reduced from 3 to 2, the end of the support rod does not need to be provided with a detachable support ball head, and compared with a pneumatic support rod, a complex pneumatic spring element is obviously not needed to be added.
The utility model provides a pair of folding vaulting pole device can realize upwards opening the support vaulting pole of cabin cover on vehicle, helicopter, the aircraft. The support rod has the advantages of simple structure, low manufacturing cost, good operability, reliability and durability, and is beneficial to improving the use and maintenance of the upper cabin cover of the helicopter and the vehicle.
The above description is only for the specific embodiments of the present invention, and the present invention is described in detail, and the detailed description is not the conventional technology. However, the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are also included in the scope of the present invention. The protection scope of the present invention shall be subject to the protection scope of the claims.
