Description
Technical Field
The utility model relates to a vehicle braking system field, concretely relates to foldable on-vehicle air brake isolation handle of subway.
Background
The existing air brake isolating device handles used on subway vehicle vehicles are all of non-foldable straight type structures. The handle is usually arranged inside a side wall plate arranged in the vehicle body, and when the pneumatic brake device is used, an operator controls the isolation and the reset of the pneumatic brake of the corresponding bogie through horizontally rotating the brake isolation handle. The movement mode of the handle can only rotate around the control valve rod in a horizontal plane, and does not have the freedom of movement in other directions.
Due to the consideration of attractive appearance and full utilization of space, the space reserved for the brake isolation handle by the built-in wall plate on the subway vehicle is smaller and smaller. The conventional non-collapsible handle can only be rotated in a horizontal plane about the control valve stem, and when the handle is in the isolated position, the tail of the handle projects out of the vertical plane in which the side wall panel is mounted. Where the side wall panels need to be specially shaped to accommodate the handle, the smoothness and overall effectiveness of the side wall panels within the vehicle is compromised.
Therefore, it is necessary to design the handle in a foldable form. The operation of a user on the vehicle is convenient, the smoothness of the built-in side wall plate is guaranteed, and the art designing effect of the vehicle is not affected.
SUMMERY OF THE UTILITY MODEL

One end of each of the two supporting rods is a quarter arc, the end faces of the supporting rods are limiting faces, and the rotation angle of the handle around the pin shaft is +/-90 degrees.
Further, the handle includes:
the sleeve and the end cover are fixedly arranged at one end of the sleeve, and the end cover is positioned at one end far away from the fixed seat;
the sleeve is a hollow cylinder, and a first flange is arranged at one end of the sleeve close to the fixed seat;
a spring mechanism is arranged in the sleeve.
Further, the spring mechanism includes:
the inner handle rod is in sliding fit with the inner cavity of the sleeve, one end of the inner handle rod is inserted into the rotating space of the handle and is rotationally connected with the fixed seat through a pin shaft, a second flange is further arranged at the circumference of the inner handle rod and is coaxial with the inner handle rod, the second flange is located in the middle of the inner handle rod, and the outer diameter of the second flange is the same as the inner diameter of the sleeve and is in sliding fit with the inner cavity of the sleeve;
the compression spring is sleeved at one end, close to the fixed seat, of the inner handle rod, and two ends of the compression spring are respectively attached to the second flange and the first flange;
the stopper, the stopper is in between end cover and the sleeve and keep away from the one end inner chamber screw-thread fit of fixing base with the sleeve, the stopper is hollow structure, the internal diameter of stopper is the same with the diameter of interior handle bar, the inner chamber sliding fit of interior handle bar and stopper, the tip of stopper and second flange form the free space of interior handle bar.
Further, still include: prevent the split pin that round pin axle and fixing base break away from.
The utility model has the advantages that: handle when guaranteeing that former handle possesses the rotary motion degree of freedom unchangeable at the horizontal direction, increase the handle at vertical planar degree of freedom of motion, when the handle is in the isolated state position, can fold the handle to with rail face vertical state, hide to between built-in side wall board and the vehicle side wall, do not influence the built-in whole effect of vehicle.
The handle adopt the round pin axle to link together handle and fixing base, increased the handle at the motion degree of freedom on vertical plane. Meanwhile, a spring is added in the handle for fixing the horizontal and vertical positions of the handle. When the handle is in the isolated state position, can fold the handle to with the rail face vertical state, hide to between built-in side wall board and the vehicle side wall, do not influence the built-in whole effect of vehicle.
Handle increase vertical planar motion degree of freedom can make the handle homoenergetic fold up in any position, its built-in space that occupies does not change because of the change of position, need not carry out built-in special molding and handles, reduce the built-in mould cost ten tens of thousands yuan of opening of single project to do not influence built-in art designer's effect, promote the competitiveness of product.

Detailed Description
The embodiment is described with reference to fig. 1 to 3, and the air brake isolation handle on the folding subway train comprises a fixed seat 1, wherein the fixed seat 1 is fixedly connected with a brake isolation valve;
the handle is rotatably connected with the fixed seat through a pin shaft 6;
wherein, the inside spring mechanism that still is equipped with of handle, the inside spring mechanism of handle is used for keeping making handle and fixing base be in the laminating state constantly.
One end of the fixed seat close to the handle is provided with a support rod 8, and the inner spaces of the two support rods 8 form a rotating space 9 of the handle; one end of the handle is inserted into the rotating space 9 of the handle and is rotatably connected with the fixed seat 1 through a pin shaft 6. One end of each of the two support rods 8 is a quarter arc, the end face of each support rod 8 is a limiting face, and the rotation angle of the handle around the pin shaft 6 is +/-90 degrees.
In this embodiment, the handle includes: the sleeve 2 and the end cover 3 are fixedly arranged at one end of the sleeve 2, and the end cover 3 is positioned at one end far away from the fixed seat 1;
the sleeve 2 is a hollow cylinder, and a first flange 10 is arranged at one end of the sleeve 2 close to the fixed seat;
a spring mechanism is arranged in the sleeve 2.
In this embodiment, the spring mechanism includes: the inner handle rod 4 is in sliding fit with the inner cavity of the sleeve 2, one end of the inner handle rod 4 is inserted into a rotating space 9 of the handle and is rotationally connected with the fixed seat through a pin shaft 6, a second flange 11 is further arranged at the circumference of the inner handle rod 4, the second flange 11 is coaxial with the inner handle rod 4, the second flange 11 is located in the middle of the inner handle rod 4, and the outer diameter of the second flange 11 is the same as the inner diameter of the sleeve 2 and is in sliding fit with the inner cavity of the sleeve 2;
