Description

Pod ventilation switching clamp

Technical Field

The utility model relates to an aircraft production mounting fixture field, concretely relates to nacelle ventilation switching anchor clamps.

Background

Because some test items of the airplane need the onboard pod to be in a working state in the assembly production process, one of the necessary conditions for the pod to work is to cool the ground ventilation meeting the air volume requirement, but because the ventilation interface of the pod is very special, common ground ventilation pipes cannot be connected, and the binding connection by cloth belts or adhesive tapes wastes time and labor, and the connection is not firm and poor in sealing property, so that the production efficiency and the quality are directly influenced.

Consequently, in order to effectively solve this problem, developed this utility model and carried out the ventilation pipe switching, can practice thrift manpower and cycle, can increase fastness and leakproofness again, stop latent quality hidden danger risk.

SUMMERY OF THE UTILITY MODEL

According to the appearance characteristics and the connection form of the nacelle ventilation interface, the nacelle ventilation switching clamp is designed and manufactured, and is small, exquisite, light, concise in operation and convenient and quick to use.

The technical scheme of the utility model as follows: a pod ventilation switching clamp comprises a pipe connector 1, a filter screen 2, a pod connector 3, a fixing column 4 and a telescopic rod 5; the pipe connector 1 is a hollow cylinder, two ends of the pipe connector are respectively communicated with the ventilating pipe and the cabin connector 3, and the pipe connector 1 and the ventilating pipe are clamped by a clamp; a filter screen 2 is arranged at the inlet of the pipe joint 1 and is used for filtering impurities blown out of the ventilation pipe; the cabin interface 3 is a hollow cuboid which is divided into a front section and a rear section, the front section is hollow and elliptical, and the rear section is hollow and rectangular; the lower part of the rear section part is provided with a V-shaped notch for avoiding the bulge at the interface of the nacelle; two sides of the rear section part are both fixed with a fixed column 4 for fixing and rebounding a telescopic rod 5; the two telescopic rods 5 are respectively connected into the cabin interface 3 through the fixing columns 4 and extend out, and are clamped into circular holes on two sides of the cabin interface when the nacelle is connected; the telescopic rod 5 is provided with a circular ring and is used for stretching outwards.

The pipe interface 1, the cabin interface 3 and the pod interface are all made of rubber materials, so that the connection tightness is guaranteed.

Filter screen 2, fixed column 4 and telescopic link 5 are stainless steel.

The pipe joint 1 has the inner diameter of about 60mm and the outer diameter of about 80mm, is used for being connected with a ventilation pipe of ground ventilation equipment, and can be clamped with the pipe joint 1 by using a common hoop;

the inner layer of the cabin interface 3 is about 80mm multiplied by 30mm, and can be tightly attached to the interface on the nacelle;

the diameter of the section of the telescopic rod 5 is 5mm, penetrates through the fixing column 4, enters the cabin interface 3, and extends out by about 6m.

The utility model has the advantages that: the utility model discloses a be used for butt joint ground ventilation pipe when aircraft nacelle work needs carry out ventilation cooling, guarantee that ground ventilation pipe and nacelle can effectual sealing connection. The utility model discloses an use the back, can guarantee the effective connection of ground ventilation pipe and nacelle, and easy and simple to handle, swift, the leakproofness has also obtained improving by a wide margin, has both avoided latent quality safety hidden danger, has also practiced thrift the cycle of preparation work in the testing process, has improved professional technical level simultaneously, has optimized the test process, produces higher economic benefits and social for scientific research production.

Detailed Description

A pod ventilation switching clamp comprises a pipe connector 1, a filter screen 2, a pod connector 3, a fixing column 4 and a telescopic rod 5; the pipe connector 1 is a hollow cylinder, two ends of the pipe connector are respectively communicated with the ventilating pipe and the cabin connector 3, and the pipe connector 1 and the ventilating pipe are clamped by a clamp; a filter screen 2 is arranged at the inlet of the pipe joint 1 and is used for filtering impurities blown out of the ventilation pipe; the cabin interface 3 is a hollow cuboid which is divided into a front section and a rear section, the front section is hollow and elliptical, and the rear section is hollow and rectangular; the lower part of the rear section part is provided with a V-shaped notch for avoiding the bulge at the pod interface; two sides of the rear section part are both fixed with a fixed column 4 for fixing and rebounding a telescopic rod 5; the two telescopic rods 5 are respectively connected into the nacelle interface 3 through the fixed columns 4 and extend out of the nacelle interface, and are clamped into circular holes on two sides of the nacelle interface when the telescopic rods are used for being connected with the nacelle; the telescopic rod 5 is provided with a circular ring and is used for stretching outwards.

The filter screen 2, the fixing column 4 and the telescopic rod 5 are made of stainless steel.

When the utility model is used, firstly, the ground ventilation pipe is sleeved on the pipe connector 1 and is clamped tightly by the clamp;

then the finger rings at the tail parts of the two telescopic rods 5 are simultaneously stretched outwards;

then sleeving the cabin interface 3 on the pod interface;

and finally, loosening the finger ring at the tail part of the telescopic rod 5 to enable the rebounded telescopic rod 5 to be just clamped in the round holes at the two sides of the pod connector, so that the switching clamp cannot fall off in the ventilation process.

After ventilation is finished, the finger rings at the tail parts of the two telescopic rods 5 are stretched outwards again, and the switching device can be detached from the nacelle.
