Lift lever, end set of the lift lever far from the third supporting rod have block, the block to be slidably disposed on institute
It states in containing cavities, the lift lever is at least partially disposed in the containing cavities, and the other end of the third supporting rod is extended
There are connecting rod, end set of the connecting rod far from the third supporting rod to have lift block, receipts are offered on the protective cover
Receive hole, the connecting rod is connected to the lift block across the reception hole.
More preferably, the upper end of the supporting table is the first spherical surface of evagination, and the spherical surface top is separately equipped with holding plane,
For placing measuring instrument, the lower end of the protective cover offers and matched second spherical surface of the spherical surface.
More preferably, the link block is to be detachably connected with the holder.
The utility model provides a kind of rail measuring instrument protective device, using protective cover can be very good to protect instrument from
Expose to the weather, protective cover can be promoted by lift block under the drive of connecting rod by extending instrument service life, and lift lever exists
It may be implemented to move synchronously under the drive of third supporting rod, when being promoted to specific position, spacing ring is detached from out of limiting slot, the
Two supporting rods may be implemented to overturn and then drive the overturning of protective cover under the action of articulated shaft so that instrument completely reveals
Come, easy to use, spacing ring can ensure that protective cover will not make second support bar generate overturning in working condition.

Specific implementation mode
Below in conjunction with the accompanying drawings, a specific implementation mode of the utility model is described in detail, it is to be understood that this
The protection domain of utility model is not restricted by specific implementation.
As shown in Figure 1 to Figure 2, a kind of rail measuring instrument protective device that the utility model embodiment provides, including holder
10, setting supporting table 11 over the mount 10, protective cover 20, the link block 30 being arranged on the holder 10, setting are connecting
First support bar 31, second support bar 32 on block 30 and third supporting rod 33 offer limiting slot, protective cover in supporting table 11
It is provided with connecting plate 21 on 20, the spacing ring 22 that can extend in limiting slot, second support bar 32 are provided on connecting plate 21
With containing cavities, one end of third supporting rod 33, which is extended, lift lever 34, end of the lift lever 34 far from third supporting rod 33
Portion is provided with block 35, and block 35 is slidably disposed in containing cavities, and lift lever 34 is at least partially disposed in containing cavities, third
The other end of supporting rod 33, which is extended, has connecting rod 331, end set of the connecting rod 331 far from third supporting rod 33 to have promotion
Block 332 offers reception hole on protective cover 20, and connecting rod 331 is connected to lift block 332 across reception hole.
Further, the upper end of supporting table 11 is the first spherical surface of evagination, and spherical surface top is separately equipped with holding plane 12, uses
In placing measuring instrument, the lower end of protective cover 20 offers and matched second spherical surface of spherical surface, the first spherical surface and the second spherical surface
It matches, can prevent rainwater from immersing, due to rainwater gravity, flow can move down, without past along the first spherical surface
Holding plane 12 flows.
