Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Embodiment
A kind of oxygen rifle is arranged with fixed ring 2 and contact ring 3 referring to Figures 1 and 2, including gun body 1 in gun body 1.Fixed ring 2
It is interference fitted with gun body 1, contacts ring 3 and 1 clearance fit of gun body, and contact the lower section that ring 3 is fixed on fixed ring 2.Oxygen rifle makes
The lifting and fixation for realizing oxygen rifle by lift cart during, contact ring 3 and lift cart is fixed, and reduce gun body 1
To the influence of contact ring 3 when inclination.Several support rods can be set between lift cart and the lower end surface of contact ring 3, will prop up
The both ends of strut are fixed with lift cart and contact 3 screw of ring respectively.In order to reduce temperature when gun body 1 works to fixed ring
2 and contact ring 3 damage, the inner sidewall of fixed ring 2 is provided with thermal insulation layer, the preferred aeroge of the material of thermal insulation layer in the present embodiment
Felt.
Referring to Figures 1 and 2, several detection devices are provided between fixed ring 2 and contact ring 3, detection device is able to detect
Whether gun body 1 is tilted out.Any detection device includes gravitation ball 5, pressure sensor 61 and connects with pressure sensor 61
The pressure display unit 62 connect.Whole gravitation balls 5 is arranged at the lower surface of fixed ring 2, and between gravitation ball 5 and fixed ring 2
By flexural pivot chain link, enable gravitation ball 5 that multidirectional rotation occurs around its hinge joint between fixed ring 2.Entirely
The gravitation ball 5 in portion can be contacted with the lateral wall of contact ring 3, and the pressure at whole gravitation balls 5 and contact 3 contact point of ring
It is identical.Thus whole gravitation balls 5 and the hinge joint of fixed ring 2 are respectively positioned on same circumference, the centre of sphere of any gravitation ball 5
Distance to contact ring 3 is identical, so the pressure value between whole gravitation ball 5 and contact ring 3 is identical.
Referring to Figures 1 and 2, contact ring 3, which is located at itself and the contact point of gravitation ball 5, offers several grooves, any groove
It is fixed with pressure sensor 61, the test side of pressure sensor 61 and the contact of corresponding gravitation ball 5, inside so as to detect
Pressure value of the gravitation ball 5 relative to contact ring 3 out.It is provided with several pressure display units 62 in gun body 1, pressure display unit 62 and right
The pressure sensor 61 answered is electrically connected, to show the pressure value between pressure sensing and gravitation ball 5.Pressure passes in the present embodiment
Sensor 61 uses piezo-electric pressure sensor 61, can be using electrical component and other devices gravitation ball 5 and pressure sensor
Pressure conversion between 61 is at electric signal, and then pressure display unit 62 receives the corresponding pressure for showing measurement after electric signal
Value.It also can choose other kinds of sensor simultaneously.Because the working principle of pressure sensor 61 and pressure display unit 62 and
Mutual connection relationship belongs to the prior art, therefore details are not described herein.
Referring to Figures 1 and 2, in order to realize the multi-faceted detection to gun body 1, whole gravitation balls 5 is uniformly arranged.Simultaneously
It is convenient for analyzing the direction of the deflection of gun body 1 by the detection device being uniformly arranged.When gun body 1 deflects, it is set in gun body 1
On fixed ring 2 can also deviate identical angle accordingly, gravitation ball 5 of the ball-joint at this time below fixed ring 2 is in its gravity
Under the action of can rotate at its hinge joint with fixed ring 2, at this time because contact ring 3 and lift cart are fixed, connect
Touching ring 3 can still be maintained horizontally disposed；Thus the pressure between each gravitation ball 5 and contact ring 3 can be because fixed ring 2 turns
It moves and changes.The power change transitions that the pressure sensor 61 contacted at this time with gravitation ball 5 will test are electric signal transmission to pressure
Power display 62, thus may determine that whether gun body 1 occurs according to the variation of the pressure value of each pressure display unit 62 display
Inclination.The change value of pressure that also can analyze each pressure display unit 62 simultaneously obtains the general offset direction of gun body 1.It needs
Bright, even if gun body 1 shifts in actual operation, offset is also smaller, and the amplitude of the rotation of gravitation ball 5 is smaller,
Because without being completely disengaged in the course of rotation with pressure sensor 61.
Referring to Fig. 2, restraining position ring block 4 is arranged in gun body 1, stop collar 4 and gun body 1 are interference fitted, and stop collar 4 can be limited and be connect
The maximum distance that touching ring 3 slides downwards.After releasing the fixation of contact ring 3 and lift cart, effect of the contact ring 3 in its gravity
Lower sliding downwards, until being contacted with stop collar 4.In order to which the impact force for reducing contact ring 3 and when stop collar 4 contacts connects to being placed on
The damage of the pressure sensor 61 inside ring 3 is touched, the upper surface of stop collar 4 is provided with buffer stopper 7, can buffer and absorb portion
Divide impact force.In order to further mitigate the impact force between contact ring 3 and stop collar 4, set between stop collar 4 and buffer stopper 7
Several elastic components 71 are equipped with, the both ends of whole elastic components 71 are fixed with stop collar 4 and buffer stopper 7 respectively.The present embodiment is hit by a bullet
The property preferred spring of part 71.
Referring to Figures 1 and 2, it is provided with protective cover in gun body 1, the detection of fixed ring 2, contact ring 3 and whole can be filled
Covering is set inside it, to reduce influence of the external environment to testing result.The material of protective cover is excellent in the present embodiment
Select suprasil.Protective cover includes the first protective cover 81 and the second protective cover 82, and the first protective cover 81 and the second protective cover 82 are right
Claim setting, be capable of forming guard space after the first protective cover 81 and the cooperation of the second protective cover 82, and the shape of protective cover can be with
For any one in sphere, cuboid and square etc..First protective cover 81 and the lateral wall of gun body 1 are fixed, the second protection
Cover 82 and the first protective cover 81 are detachably connected.The first protective cover 81 can be more by welding, screwing etc. in the present embodiment
Kind mode realizes the fixation of itself and 1 lateral wall of gun body.Second protective cover 82 and the first protective cover 81 can be solid by fastening screw
Fixed, the fixation of the first protective cover 81 and the second protective cover 82 for convenience, the first protective cover 81 and the second protective cover 82 mutually lean on
Close end face, which is extended, flange, can be realized consolidating for the first protective cover 81 and the second protective cover 82 by fixing two flanges
It is fixed.
Referring to Fig.1, for the ease of observe each pressure display unit 62 pressure value variation, will be whole in the present embodiment
