Description
Technical Field
The utility model belongs to hand power BB rifle especially relates to detection device of hand power BB rifle gas tightness.
Background
Whether air leakage exists is judged by detecting the strength of bullet firing force during detection of the existing hand-pulled gun finished product gun, and the strength has a certain range during force testing. For the small air leakage, the bullet firing strength is in the detection range, and the misjudgment can occur.
Disclosure of Invention
The utility model aims to overcome the weak point that exists when present hand power rifle finished product rifle gas tightness detects, provide one kind and can effectively prevent the erroneous judgement, can accurately judge the detection device of hand power rifle gas tightness whether gas leakage of hand power rifle.
The utility model discloses the technical scheme who adopts is a detection device of hand power rifle gas tightness, its main points lie in, it is by the atmospheric pressure test meter, the connecting piece, the sealing washer is constituteed, the one end of connecting piece meets with the inlet end of atmospheric pressure test meter, the inlet end of atmospheric pressure test meter is the external screw thread, the connecting piece is matched with screw with it, the hole that is for lining up at the connecting piece center, communicate with each other with the centre bore of atmospheric pressure test meter, the other end of connecting piece is the barrel link, the appearance is the cylindricality, the external diameter cooperatees with the internal diameter of hand power rifle barrel, the head lateral surface design of barrel link has the seal ring groove, the seal ring cover is in.
The barrel connecting end of the connecting piece is provided with two sealing ring grooves.
The aperture of the central hole of the connecting piece is not larger than that of the central hole of the air pressure test meter.
The utility model discloses an utilize current atmospheric pressure test table, made the connecting piece of joining in marriage with the hand power rifle is special, guarantee the gas tightness between connecting piece and the hand power rifle through the sealing washer. The operation mode is as follows: after the hand-pulling gun is loaded (under the condition of no bullet), an air-tight device is installed, and the trigger is pulled to see the swinging condition of the pointer. The pointer does not fall to a place with a small numerical value after rotating to a certain index, which proves that the air tightness is good, no air leakage exists in the pointer, the pointer is a qualified product, otherwise, the pointer cannot meet the requirement of a finished product gun. The utility model discloses simple structure, convenient to use, whether the direct detection leaks gas, and the testing result is clear and definite, and the erroneous judgement rate is low.
Drawings
FIG. 1 is a diagram of the usage state of the present invention
FIG. 2 is an exploded view of the present invention
Fig. 3 is a cross-sectional view of the present invention
Wherein: 1 air pressure test meter, 2 connecting pieces, 21 sealing ring grooves, 3 sealing rings and 4 hand-pulling guns.
Detailed Description
The present invention is described in detail below with reference to the drawings so that those skilled in the art can understand the present invention more clearly.
As shown in fig. 1-3, a hand-pull gun airtightness detection device is composed of an air pressure test meter 1 (0.25 MPa), a sealing ring 3 (purchased part), and a connecting piece 2 (self-made part), wherein the sealing ring is generally an O-shaped sealing ring, one end of the connecting piece is connected with an air inlet end of the air pressure test meter, the air inlet end of the air pressure test meter is an external thread, the connecting piece is a screw hole matched with the connecting piece, the center of the connecting piece is a through hole and communicated with a center hole of the air pressure test meter, and the aperture of the center hole of the connecting piece is not larger than that of the center hole of the air pressure. The other end of the connecting piece is a gun tube connecting end, the shape is cylindrical, the outer diameter of the connecting piece is matched with the inner diameter of a gun tube of a hand-pulling gun, a sealing ring groove 21 is designed on the outer side face of the head of the gun tube connecting end, two sealing ring grooves are formed in the outer side face of the head of the gun tube connecting end, and two O-shaped sealing rings are sleeved in the sealing ring grooves. When the hand-pulling gun is used, after the hand-pulling gun is loaded (under the condition of no bullet), one end of the O-shaped sealing ring connecting piece sleeved on the device is inserted into the head of the hand-pulling gun barrel, and the trigger is pulled to see the swinging condition of the pointer. The pointer does not fall to a place with a small numerical value after rotating to a certain index, which proves that the air tightness is good, no air leakage exists in the pointer, the pointer is a qualified product, otherwise, the pointer cannot meet the requirement of a finished product gun.
