Specific embodiment
With reference to specification drawings and specific embodiments, the present invention is further described.
Embodiment 1 can be used for bicycle, this chain of motorcycle exposure situation outside.As shown in Fig. 1 is to 5, this
Bright embodiment 1 includes the housing 10 of upper opening, and middle is a vertical sprocket wheel 11, and the present invention is located with described sprocket wheel 11
Plane symmetrically structure.Sprocket wheel 11 center is fixedly connected a trunnion axis 9, and the two ends of trunnion axis 9 are rotated with housing 10 and are connected.Sprocket wheel
11 both sides are respectively provided with a horizontal bevel gear 12 being fixed on trunnion axis 9, and described horizontal bevel gear 12 is respectively vertically bored with one
Gear 13 is meshed.Described vertical bevel gear 13 top is fixedly connected a hollow shaft 8, the described hollow shaft 8 at least first half
It is divided into hollow structure, nested one or more sleeve 17 structures of described hollow shaft 8 outer surface, described sleeve 17 structure and institute
The housing 10 stated is fixedly connected.
During use, chain 18 to be detected is placed in the upside of described sprocket wheel 11, the pin with chain 18 in described hollow shaft 8
Sub 19 contour positions are provided with multiple detection holes, and the quantity in described detection hole is even number.It is provided with detection in the cavity of hollow shaft 8
Part 15, described detection piece 15 includes the vertical cylinder body of hollow and is fixed on radially distributing on cylindrical side
Multiple Horizontal Cylinders 16, the quantity of described Horizontal Cylinder 16 is equal to the quantity in described detection hole, Horizontal Cylinder 16
Diameter be less than the internal diameter in detection hole, the end of Horizontal Cylinder 16 is located at detection in the hole, and therefore detection piece 15 can be hollow
Carry out a range of movement in the cavity of axle 8.Elastic shaft 14 is passed through in described detection piece 15 vertical cylinder body middle cavity,
Described elastic shaft 14 is made up of elastomeric material, and its lower end is fixedly connected with described hollow shaft 8, and upper end is stretched in hollow shaft 8
Go out, upper end is pointer 2, in elongate shape, and the position that elastic shaft 14 is located in the middle of detection piece 15 vertical cylinder is provided with chondritic
3, the mid portion of described vertical cylinder body cavity is in spherical with described chondritic 3 identical.The top of hollow shaft 8,
It is provided with dial 1, described dial 1 is fixed on hollow shaft 8 or housing 10, can be read on dial 1 by pointer 2
Scale.
On described housing 10, the outside of detection piece 15 be provided with screwed hole and the cored screw 4 matching with screwed hole, institute
It is provided with interior carefully outer thick shoulder hole, ladder in the hole is provided with outer slightly interior thin push rod 6, the thick section of push rod 6 in the middle of the cored screw 4 stated
Part is exposed from ladder in the hole, is provided with spring 7, this spring 7 is enclosed within push rod 6 thin segment, by spring 7 in the thick section of shoulder hole
Push rod 6 the inner back in the cavity of cored screw 4 for effect, the inner rotation hindering described hollow shaft 8 of anti-throw-out lever 6
Turn.The outer end of cored screw 4 is hinged with handle 5, as shown in figure 4, the end points of hinged end and the distance of pin joint are little on handle 5
In the distance of pin joint and wherein one side, it is connected by smooth curve edge between hinged end and this side, in this region
Interior formation one cam 20 structure.
Operating process is as follows：During use, chain 18 to be detected is placed on described sprocket wheel 11, promotes chain 18 forward
Walk about, band movable sprocket 11 rotates simultaneously, dynamic bevel gear rotation is carried by described trunnion axis 9, and then drives described hollow shaft 8
Rotation, described detection piece 15 rotates around elastic shaft 14 therewith, and the pin 19 on detection hole and chain 18 in hollow shaft 8 is one by one
Align.If certain pin 19 position on chain 18 there occurs skew, as shown in figure 5, then this pin 19 promotes on detection piece 15
Corresponding trunnion axis 9 offset, detection piece 15 drives described elastic shaft 14 to offset, after side-play amount being amplified through elastic shaft 14,
Side-play amount is read by pointer 2, dial 1, then the pin 19 of skew is corrected.First will be hinged around it for handle 5
Point rotates 90 °, and by the effect of the cam 20 of its end, by described push rod 6, quick promotion makes it on detection piece 15 inwards
Corresponding trunnion axis 9, then hand-held handle 5, rotate around cored screw 4 so as to precession inwards, inspection promoted by catch bar
Survey part 15 to move inwards, promote pin 19 mobile by detection piece 15, when pointer 2 return, pin 19 returns to correct position.
Thus effectively prevent offset because of pin 19, cuff link comes off the phenomenon that the chain 18 leading to disconnects.
And in Medical Devices or care appliances, such as it is freely lifted sick bed, limb rehabilitating telecontrol equipment, wheelchair-style walking device for moving on stairs
Deng, due to being public situation, chain can not expose outside, in prior art need to take backplate apart safeguarded, Zhi Nengtong
Cross special maintenance personnel to be operated.Embodiment 2 provides one kind more shirtsleeve operation mode, and medical personnel can be from enforcement
Pass through chain oiling or maintenance window with this instrument, voluntarily regular maintenance is carried out for the Medical Devices with chain, decreases
Medical equipment failure rate is it is ensured that the normal work of hospital.
In embodiment 2, the technical characteristic do not mentioned in the present embodiment is all same as Example 1.As shown in fig. 6, it is described
The hole that housing 10 is located at push rod 6 is unthreaded hole, and described push rod 6 is located in this hole, and housing 10 is fixedly connected a platform 22, institute
The handle 5 stated is hinged with this platform 22, and hinged place is provided with torsion spring (not shown), makes handle by the elastic reaction of torsion spring
5 are in the direction parallel to push rod 6.Be connected by connecting rod 21 between described push rod 6 and handle 5, connecting rod 21 two ends respectively with
Push rod 6 and handle 5 are hinged, wherein the company of the pin joint between the pin joint between connecting rod 21, handle 5 and handle 5, platform 22
Line is perpendicular to the axis of handle.
When pin 19 offsets, turning handle 5, promote push rod to move inwards by connecting rod 21.When at the uniform velocity rotary handle 5
When, push rod 6 speed is from fast to slow, when handle 5 rotate 90 degree after, mechanism is in dead-centre position, now to push rod 6 most exert oneself
Greatly, because the firm setting in motion space-time of push rod 6 pushes away, quick promotion can make push rod 6 quickly move, rear push-rod 6 promote detection piece
15 so promote pin 19 reset, now mechanism moves closer to dead-centre position, and the active force of push rod 6 is gradually increased, therefore logical
Crossing this mechanism can easily promote pin 19 mobile.
It should be noted that the particular of the present invention is to the present invention have been described in detail, for ability
For the technical staff in domain, various obviously change to what it was carried out without departing from the spirit and scope of the present invention
Become all within protection scope of the present invention.
