Specific embodiment
With reference to specification drawings and specific embodiments, the present invention is further described.
Embodiment 1 can be used for this chain exposure of bicycle, motorcycle situation outside.As shown in Fig. 1 to 5, this hair
Bright embodiment 1 includes the housing 10 of upper opening, and centre is a vertical sprocket wheel 11, and chain service kit is with described sprocket wheel 11
The plane at place is in symmetrical structure.The center of sprocket wheel 11 is fixedly connected a trunnion axis 9, and the two ends of trunnion axis 9 rotate with housing 10 and connect
Connect.The both sides of sprocket wheel 11 are respectively provided with a horizontal bevel gear 12 being fixed on trunnion axis 9, and described horizontal bevel gear 12 is respectively with one
Vertical bevel gear 13 is meshed.The described top of vertical bevel gear 13 is fixedly connected a hollow shaft 8, and described hollow shaft 8 is at least
Top half is hollow structure, nested one or more structures of sleeve 17 in the described outer surface of hollow shaft 8, the described knot of sleeve 17
Structure is fixedly connected with described housing 10.
When using, chain to be detected 18 is placed in the upside of described sprocket wheel 11, the pin in described hollow shaft 8 with chain 18
Sub 19 contour positions are provided with multiple detection holes, and the quantity in described detection hole is even number.Detection is provided with the cavity of hollow shaft 8
Part 15, described detection piece 15 includes hollow vertical cylinder body and is fixed on radially distributing on the side of cylinder
Multiple Horizontal Cylinders 16, the quantity of described Horizontal Cylinder 16 is equal to the quantity in described detection hole, Horizontal Cylinder 16
Internal diameter of the diameter less than detection hole, the end of Horizontal Cylinder 16 is located in detection hole, therefore detection piece 15 can be hollow
A range of movement is carried out in the cavity of axle 8.Elastic shaft is passed through in the described vertical cylinder body middle cavity of detection piece 15
14, 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 from hollow shaft 8
Stretch out, upper end is pointer 2, in elongate shape, and the position that elastic shaft 14 is located in the middle of the vertical cylinder of detection piece 15 is provided with spherical knot
Structure 3, the center section of described vertical cylinder body cavity is in spherical with the described identical of chondritic 3.Hollow shaft 8 it is upper
Side, is provided with dial 1, and described dial 1 is fixed on hollow shaft 8 or housing 10, can be on dial 1 by pointer 2
Read scale.
On described housing 10, the outside of detection piece 15 be provided with screwed hole and the cored screw 4 matched with screwed hole, institute
Interior thin outer thick shoulder hole is provided with the middle of the cored screw 4 stated, outer thick interior thin push rod 6, the thick section of push rod 6 are provided with shoulder hole
Part is exposed from shoulder hole, and spring 7 is provided with the thick section of shoulder hole, and the spring 7 is enclosed within the thin segment of push rod 6, by spring 7
Back into the inner of push rod 6 in the cavity of cored screw 4 by effect, the rotation of the hollow shaft 8 described in the inner obstruction 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 small on handle 5
In the distance of pin joint Yu a wherein side, it is connected by smooth curve edge between hinged end and the side, handle is hinged
End forms the structure of a cam 20.
Operating process is as follows：When using, chain 18 to be detected is placed on described sprocket wheel 11, promotes chain 18 forward
Walk about, while band movable sprocket 11 rotates, rotated with dynamic bevel gear by described trunnion axis 9, and then drive 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 position of pin 19 on chain 18 there occurs skew, as shown in figure 5, then the pin 19 is promoted on detection piece 15
Corresponding trunnion axis 9 offset, detection piece 15 drives described elastic shaft 14 to offset, after through elastic shaft 14, side-play amount is amplified,
Side-play amount is read by pointer 2, dial 1, then the pin 19 for offseting is corrected.Handle 5 is hinged around it first
Point is rotated by 90 °, and quickly being promoted described push rod 6 inwards by the effect of the cam 20 of its end is made on its close detection piece 15
Corresponding trunnion axis 9, then hand-held handle 5, rotate around cored screw 4, make its precession inwards, by catch bar promote examine
Survey part 15 to move inwards, promote pin 19 to move by detection piece 15, when 2 return of pointer, pin 19 returns to correct position.
So as to effectively prevent offset because of pin 19, cuff link comes off the phenomenon of the disconnection of caused chain 18.
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 the prior art need to take backplate apart safeguarded, Zhi Nengtong
Special maintenance personnel are crossed to be operated.Embodiment 2 provides a kind of more shirtsleeve operation mode, and medical personnel can be from enforcement
With the instrument by chain oiling or maintenance window, voluntarily regular maintenance is carried out for the Medical Devices with chain, reduced
Medical equipment failure rate, it is ensured that the normal work of hospital.
In embodiment 2, the technical characteristic do not mentioned in the present embodiment is same as Example 1.As shown in fig. 6, described
The hole that housing 10 is located at push rod 6 is unthreaded hole, and described push rod 6 is located in the hole, and a platform 22 is fixedly connected on housing 10,
Described handle 5 is hinged with the platform 22, and hinged place is provided with torsion spring (not shown), and hand is made by the elastic reaction of torsion spring
Handle 5 is in the direction parallel to push rod 6.Connected by connecting rod 21 between described push rod 6 and handle 5, the two ends of connecting rod 21 difference
It is hinged with push rod 6 and handle 5, wherein the pin joint between connecting rod 21, handle 5 and the pin joint between handle 5, platform 22
Axis of the line perpendicular to handle.
When pin 19 offsets, handle 5 is rotated, promote push rod to move inwards by connecting rod 21.When at the uniform velocity rotary handle 5
When, the speed of push rod 6 is from fast to slow, and after handle 5 rotates 90 degree, mechanism is in dead-centre position, now most exerting oneself most to push rod 6
Greatly, because the firm setting in motion space-time of push rod 6 is pushed away, quick promotion can be such that push rod 6 quickly moves, rear push-rod 6 promote detection piece
15 and then pin 19 is promoted to reset, now mechanism moves closer to dead-centre position, and the active force to push rod 6 is gradually increased, therefore logical
Crossing the mechanism can easily promote pin 19 to move.
It should be noted that particular of the 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.
