It is pointed out that in this article, " inner side ", " outside " are for the center of locking mechanism, are called inner side near the center of locking mechanism, and the center away from locking mechanism is called outside, and this meets the general custom of those skilled in the art.
The utility model provides a kind of locking mechanism, comprises handle, briquetting, the first connecting shaft, the second connecting shaft and coupling.First connecting shaft is coaxially connected by coupling with the second connecting shaft, and is each passed through corresponding briquetting, and the first connecting shaft and the second connecting shaft are provided with the contrary screw thread of rotation direction.
Each briquetting is provided with for the first connecting shaft or the second connecting shaft through and the tapped hole of screw-thread fit with the first connecting shaft or the second connecting shaft; thus when the first connecting shaft and the second connecting shaft rotate simultaneously; by the cooperation of screw thread, two briquettings can be driven to draw close to the inside simultaneously or be separated laterally simultaneously.The inner top side of each briquetting is provided with the scarf can be close to the mobile platform of torque standard device; inside lower end is provided with the scarf can be close to the base of torque standard device; thus when two briquettings are drawn close to the inside or are separated laterally simultaneously simultaneously, mobile platform can be locked with base or separate.
Handle is fixedly connected with the first connecting shaft outboard end, and the rotation of handle can drive the first connecting shaft to rotate.
Handle can shake, and can be in locking state and releasing orientation, in the locked condition, mobile platform and base are locked, and mobile platform can not move freely relative to base, at releasing orientation, mobile platform and base released, mobile platform can move relative to base.
Under preferable case, locking mechanism also can comprise the sensing device being in locking state or releasing orientation for detecting handle.Sensing device can comprise cam and sensor, and cam is fixedly installed on the outboard end of the second connecting shaft, the position that sensor setting is corresponding with cam on briquetting.Sensor can detect the pivotal position of cam, and then detects the position of handle.
Under preferable case, locking mechanism also can comprise and is arranged at the side of coupling and/or the support of both sides, for supporting the first connecting shaft and/or described second connecting shaft, prevents the first connecting shaft, the second connecting shaft sagging because of Action of Gravity Field.In order to improve support effect, support can be fixedly attached to mobile platform.
Described locking mechanism can be arranged on the mobile platform of torque standard device, can move and move by mobile platform 4.The used time does not detachably get off yet.
Fig. 1 is the structural representation of the locking mechanism according to exemplary embodiment.As shown in Figure 1, handle 1, briquetting 2, first connecting shaft 3, second connecting shaft 6 and coupling 5 is comprised according to the locking mechanism of exemplary embodiment.
First connecting shaft 3 is coaxially connected by coupling 5 with the second connecting shaft 6, and after namely connecting, the first connecting shaft 3 and the second connecting shaft 6 are coaxially, thus when a connecting shaft rotates, another root connecting shaft can be driven to rotate simultaneously.First connecting shaft 3 and the second connecting shaft 6 are provided with screw thread, and the screw thread of the first connecting shaft 3 is contrary with the thread rotary orientation of the second connecting shaft 6, if namely the screw thread of the first connecting shaft 3 is right-handed thread, then the screw thread of the second connecting shaft 6 is left-handed thread, otherwise or.First connecting shaft 3 and the second connecting shaft 6 are each passed through corresponding briquetting 2.
Each briquetting 2 is provided with for the first connecting shaft 3 or the second connecting shaft 6 through and the tapped hole of screw-thread fit with the first connecting shaft 3 or the second connecting shaft 6, thus when connecting shaft rotates, screw thread can promote briquetting and move, and is similar to screw mandrel slide block structure.And due to the screw thread of the first connecting shaft 3 contrary with the thread rotary orientation of the second connecting shaft 6, therefore when connecting shaft rotates, briquetting 2 movement direction of both sides is contrary.The upper and lower two ends, inner side of each briquetting 2 are provided with scarf, and upper end scarf can be close to mobile platform 4, and lower end scarf can be close to base 9.
Handle 1 is fixedly connected with the first connecting shaft 3 outboard end, thus handle 1 rotation can drive the first connecting shaft 3 to rotate.
A whole set of locking mechanism is arranged on the mobile platform 4 of torque standard device, can move and mobile with mobile platform 4.
In the preferred case, be fixedly installed cam in the outboard end of the second connecting shaft 6, briquetting 2 correspond to cam position sensor 7 is set.Cam follows handle 1, first connecting shaft 3 and the second connecting shaft 6 synchronous axial system, and when the projection of cam is near sensor 7, sensor 7 sends signal, when the projection of cam leaves sensor 7, and sensor 7 no signal.By the signal condition of monitoring sensor 7, can determine that handle 1 is in locking state or releasing orientation.Sensor 7 is such as photoelectric position sensor.
In the preferred case, can also arrange support in the side of coupling 5 and/or both sides, support can be fixedly attached to mobile platform 4, for supporting the first connecting shaft 3 and/or the second connecting shaft 6, prevents it sagging due to gravity effect.
With reference to figure 1 and Fig. 2, the using process according to the locking mechanism of exemplary embodiment is described.In using process, the first connecting shaft 3 connected by coupling 5 and the second connecting shaft 6 pass the central aperture of mobile platform 4, and do not contact with mobile platform 4, and briquetting 2 is installed on mobile platform 4 two ends.Handle 1 is shaken clockwise to " unclamping " state, the rotation of handle 1 drives the first connecting shaft 3 and the second connecting shaft 6 to rotate clockwise simultaneously, because the screw thread on connecting shaft and the corresponding threaded holes on briquetting close, and the thread rotary orientation of two connecting shafts is contrary, promote two briquettings 2 by screw thread to separate to both sides, mobile platform 4 and base 9 unclamp, and mobile platform can move freely on guide rail 8.
Handle 1 is shaken to " locking " state counterclockwise, the rotation of handle 1 drives the first connecting shaft 3 and the second connecting shaft 6 to rotate counterclockwise simultaneously, because the screw thread on connecting shaft and the corresponding threaded holes on briquetting close, and the thread rotary orientation of two connecting shafts is contrary, two pieces of briquettings 2 come closer simultaneously, inside briquetting 2 scarf squeezing action under, mobile platform 4 is compacted with base 9, and mobile platform 4 can not move on guide rail 8.Therefore, swinging handle can realize mobile platform 4 both sides and locks simultaneously.
Compared with prior art, the beneficial effects of the utility model there is provided a kind of locking mechanism, effectively can not only lock mobile platform, and easy to operate, only need an action can realize mobile platform both sides and lock simultaneously, namely achieve " one-touch " operation.Locking mechanism of the present utility model is more stable than common locking device locking effect, and stress is more reasonable.In addition, locking mechanism of the present utility model can arrange sensing device, can detect locking mechanism and be in locking state or releasing orientation, and externally provide automatically controlled signal, prevent misoperation.
Apply concrete example herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
