Description
Technical field
The present invention relates to grasp field, more particularly to a kind of steering grasp for being capable of measurement distance.
Background technology
Rangefinder can be divided into following three class from ranging general principle：Laser range finder be using laser to target away from
From the instrument for carrying out Accurate Determining.Laser range finder operationally projects a branch of very thin laser to target, is connect by photoelectric cell
The laser beam of target reflection is received, timer determines laser beam from the time for being transmitted into reception, calculated from observer to target
Distance.Laser range finder is current the most widely used rangefinder, and laser range finder can be categorized as Handheld laser survey again
Distance meter（0-300 meters of measurement distance）, telescope laser range finder（500-3000 meters of measurement distance）.Ultrasonic range finder is root
Run into what the characteristic that barrier reflects was measured according to ultrasonic wave.Ultrasonic transmitter launches ultrasonic wave to a direction,
Timing is started simultaneously in transmitting, ultrasonic wave is propagated in atmosphere, barrier is encountered in way and just returns to come immediately, ultrasonic receiver
Receive back wave and just interrupt immediately and stop timing.The echo that barrier is reflected is run into by constantly detecting to produce after ripple is launched,
So as to measure transmitting ultrasonic wave and receive the time difference T of echo, then obtain apart from L.Ultrasonic range finder, due to ultrasonic wave
Larger by surrounding environment influence, so general measure distance is shorter, measurement accuracy is than relatively low.The use of scope is not at present very wide
It is wealthy, but price is than relatively low, general hundreds of yuan or so.The instrument of precise distance measurement is carried out with the infrared light of modulation, ranging is generally 1-5
Kilometer.What is utilized is indiffusion principle when infrared ray is propagated：Because infrared ray refractive index very little when passing through other materials, institute
Infrared ray can all be considered with the rangefinder of long range, and ultrared propagation needs the time, when infrared ray is sent out from rangefinder
Go out to encounter reverberation and be reflected back and received by rangefinder further according to infrared ray from being issued to time for being accepted to and infrared
The spread speed of line can just calculate distance, and the advantage of infrared distance measurement is cheap, is easily made, and safety has the disadvantage that precision is low, distance
Closely, directionality is poor.
Bow and crossbow are used as a kind of weapon very early in China.Crossbow is to create to come on the basis of bow, due to
Limited by muscle power, people pulls open bow can not be lasting, in order to extend the time drawn a bow, preferably aims at, our ancestors' invention
Crossbow.Crossbow is main to be made up of bow and crossbow arm two parts, is filled on bow and is filled the trigger mechanism of a crossbow on string, arm, both coordinate and shot arrows.The use of crossbow,
It is first string is pulled open to be buckled on the trigger mechanism of a crossbow, it is to be captured when arriving best launching time, move " outstanding knife "（Trigger）, arrow is projected
Go.The earliest trigger mechanism of a crossbow is to have played " time-delay mechanism ", and later by updating, the performance of crossbow is become better and better, species
It is more and more.Still it is fan and collector as a kind of ancient shooting equipment although present crossbow is no longer used to weapon
Doted on, therefore to its Improvement also in lasting progress.Although the structure change of crossbow, innovations in pattern or design determines that its is basic
The ejection mechanism of performance is substantially unchanged, i.e., drive crossbow bolt action with the elastic force of bow.The crossbow of prior art is remained as follows not
Foot, first by the limitation of traditional " bow " structure, it is impossible to provide longer crossbow bolt boosting slideway, the basic tension force in short-term by bow is pushed away
Dynamic crossbow bolt, its thrust is restricted, i.e., crossbow bolt can not be made to obtain enough impulse forces, and range is not good, and slideway is shorter also unfavorable in addition
Keep stable in a transmit direction in crossbow bolt；Secondly, the general armrest arm of the crossbow of prior art lifts support transmitting, and is inconvenient to take aim at
Standard, hit rate is relatively low；Again, string is pulled open by arm and is buckled on the trigger mechanism of a crossbow, operation is laborious, thus bow can not be done it is too strong
Firmly, which also limits the range of crossbow.
For a long time, the safety measure that operation of ascending a height is taken Shortcomings always, only by operator's self-ability of ascending a height
To ensure safety.If the operator that ascends a height makes a fault during climbing, accidentally drop fall for the moment, easily lead to serious personnel
High falling injury accident.According to both at home and abroad from the point of view of disclosed data, for steel vertical ladder climbing using more anti-
Drop device, it is desirable to have seizing wire is through vertical ladder top pulleys or is fixed on steel vertical ladder, for installing this device
The first place operating personnel that ascends a height but can not effectively be protected, and this device climbs also and inconvenient.Therefore, lack a kind of
The device that operating personnel climbs vertical ladder can be substituted, and when developing this climbing device, it is necessary to a kind of device of fixing
Hook, traditional gib head its support force deficiency are climbed, and is difficult to clasp supporter during exercise, is easily broken off relations.
