Abstract
The utility model discloses a kind of safe and reliable velocity sensor for avoiding sensing head encapsulating shell from dropping on measure speed gearses, there is sensor installation seat, the front end of sensor installation seat is bolted the sensing head encapsulating shell being placed in sensor installation seat, sensing head is placed in sensing head encapsulating shell, sensing head is connected by printed wiring board with cable, there is boss on the lateral surface of the sensing head encapsulating shell, there is the limiting stand for preventing sensing head encapsulating shell play forward to match with boss in sensor installation seat, there is installing port on the side of sensor installation seat, there is cap on installing port.The utility model can effectively prevent sensing head encapsulating shell play vertically, be slid prevented also from sensing head encapsulating shell to the gear of high-speed rotation, avoid therefore caused by major accident, securely and reliably.
Description
Technical field
The utility model is related to a kind of sensor, especially one kind can avoid sensing head encapsulating shell from dropping on measure speed gearses
Safe and reliable velocity sensor.
Background technology
Existing velocity sensor has sensor installation seat, is sequentially provided with sensing head encapsulation in sensor installation seat from front to back
Shell, printed wiring board and cable, cable are fixed on sensor installation seat with water joint, and sensing head is placed in sensing head envelope
Fill in shell, connected by printed wiring board with cable.Sensing head encapsulating shell install when be from sensor installation seat axially by
Install, be fixed after installing by the countersunk head hexagon socket head cap screw positioned at sensor installation seat side inside outside.Due to speed
Degree sensor needs and outside measure speed gearses are supporting tests the speed, and such as countersunk head hexagon socket head cap screw loosens because vibrating, do not fasten reason,
It this may result in sensing head encapsulating shell to drop on the measure speed gearses that height rotates, then trigger major accident.
The content of the invention
The utility model is to solve the above-mentioned technical problem present in prior art, there is provided one kind can avoid sensing head
The safe and reliable velocity sensor that encapsulating shell is dropped on measure speed gearses.
Technical solution of the present utility model is：A kind of safe and reliable velocity sensor, there is sensor installation seat, passes
The front end of sensor mounting seat is bolted the sensing head encapsulating shell being placed in sensor installation seat, and sensing head is placed in sensing
In head encapsulating shell, sensing head is connected by printed wiring board with cable, has boss on the lateral surface of the sensing head encapsulating shell,
There is the limiting stand for preventing sensing head encapsulating shell play forward to match with boss in sensor installation seat, installed in sensor
There is installing port on the side of seat, there is cap on installing port.
The utility model can be installed in place from installing port by sensing head encapsulating shell, the boss on sensing head encapsulating shell lateral surface
Interacted with the limiting stand in sensor installation seat, can effectively prevent sensing head encapsulating shell play vertically, even if spiral shell occurs
Bolt loosen, slid prevented also from sensing head encapsulating shell to the gear of high-speed rotation, avoid therefore caused by major accident, peace
It is complete reliable.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings specific embodiment of the present utility model.As shown in Figure 1：Compared with technology, there is biography
Sensor mounting seat 1, the front end of sensor installation seat 1 is fixed with by countersunk head hexagon socket head cap screw 2 to be placed in sensor installation seat 1
Sensing head encapsulating shell 3, sensing head 4 are placed in sensing head encapsulating shell 3, and sensing head 4 is connected by printed wiring board 5 with cable 6,
Cable water joint 11 is fixed on sensor installation seat 1, with prior art except that sensing head encapsulating shell 3 it is outer
There is boss 7 on side, there is the limit for preventing the play forward of sensing head encapsulating shell 3 to match with boss 7 in sensor installation seat 1
Position platform 8, has installing port 9 on the side of sensor installation seat 1, there is cap 10 on installing port 9.
During installation, the sensing head encapsulating shell 3 for being built-in with sensing head 4 is placed in sensor installation seat 1 by installing port 9,
Boss 7 is placed on limiting stand 8, is fixed again with countersunk head hexagon socket head cap screw 2 afterwards, by casting glue embedding, lid after integral installation
Upper shell cover 10.The play forward of sensing head encapsulating shell 3 can be prevented, sensing head encapsulating shell can be avoided to slide to the gear of high-speed rotation
On.
