Abstract
The utility model provides a locking device for a self-leveling ink line device, including a locking wheel, a shell, a cam wheel and three enclasping devices from the outside and in orderly. Every enclasping device includes a enclasping jaw, a torsional spring, a pin roll and a pin blot. The enclasping jaw is a lever structure with certain included angle. The torsional spring is equipped on the pin roll. The pin roll and the pin bolt are fixed on the surface of the shell. The cam wheel is provided with three flanged lips and limited blocks corresponding with the position of the enclasping device and rotates with the locking wheel. The utility model is characterized in that: the locking state is the same as the operation state, with even stress, guaranteeing the precision of the device, with the advantages of simple structure, reasonable design and reliable locking.
Description
Technical field
The utility model relates to the self leveling marker, relates in particular to the locking device in the self leveling marker.
Background technology
In the self leveling marker, the goods of furniture for display rather than for use of instrument internal is in the vertical state automatically under action of gravity, and level, vertical a plurality of laser instruments are installed on the goods of furniture for display rather than for use.In the instrument transportation, the necessary fixing and locking of goods of furniture for display rather than for use, correct with the relative position of protection goods of furniture for display rather than for use and last laser instrument thereof.At present, most of like products all are by lever or pin goods of furniture for display rather than for use to be leaned on inwall, and its structure as shown in Figure 1.When 6 ' time of rotational lock handwheel, drive offset cam 4 ' overcome stage clip 5 ' pressure make lever 3 ' action, with goods of furniture for display rather than for use 1 ' lean inwall 2 ' on.This locking device makes goods of furniture for display rather than for use be subjected to side force, damages the self leveling system easily.
Summary of the invention
The purpose of this utility model provides the locking device in a kind of self leveling marker that can overcome above-mentioned shortcoming.It makes, and goods of furniture for display rather than for use is stressed when locking has evenly protected pendulum mass well, has guaranteed the accurate of instrument.
The purpose of this utility model is to realize by following technical solution.Design the locking device in a kind of self leveling marker, it comprises from outside to inside successively: locking wheel, housing, cam and three enclasp devices, and each enclasp device comprises: hold pawl, torsion spring, bearing pin and pin tightly; The described pawl of holding tightly is the lever construction that certain angle is arranged, and described torsion spring is installed on the bearing pin, and described bearing pin and pin are fixed on the plane of housing; Described cam is provided with corresponding with the enclasp device position three flanges and limited block, and cam is followed the locking wheel rotation.
Locking device in the self leveling marker of the present utility model has the following advantages:
1, locking state is identical with duty, and stressed even, has guaranteed the accurate of instrument.
2, simple in structure, reasonable in design, reliable lock.
Description of drawings
Fig. 1 is the structural representation of locking device in the existing self leveling marker;
Fig. 2 is the structural representation of locking device in the self leveling marker of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, further specify the utility model.
With reference to Fig. 2, the locking device in the self leveling marker of the present utility model comprises from outside to inside successively: locking wheel 6, housing 10, cam 5 and three enclasp devices 3, and each enclasp device 3 comprises again: hold pawl 7, torsion spring 4, bearing pin 9 and pin 8 tightly; Hold pawl 7 tightly for the lever construction of certain angle is arranged, bearing pin 9 and pin 8 are fixed on the plane of housing 10, and torsion spring 4 is installed on the bearing pin 9, and an end embeds and holds tightly in the pawl 7, and the other end is stuck in pin 8 places; Cam 5 is provided with corresponding with enclasp device 3 positions three flanges 51 and limited block 52, and cam 5 is followed locking wheel 6 and rotated together.
In the such scheme, described three enclasp devices 3 are uniform in housing 10 circumference, evenly force on the goods of furniture for display rather than for use 1 so that hold pawl 7 tightly.
In the such scheme, on the described cam 5 groove 53 is set, is provided with embeddable protruding 61 on the locking wheel 6.Housing 10 is provided with chute 101.
In the such scheme, high protruding 512 shapes in indentation 511 both sides in the middle of the shape of described flange 51 is.
In the such scheme, the described pawl 7 of holding tightly is long and short arm 71,72 lever constructions, and long-armed 71 end in contact goods of furniture for display rather than for uses 1.
In the such scheme, the described pawl 7 held tightly is 110～145 ° for the angle of 71,72 on long and short arm.
When locking wheel 6 clockwise direction are rotated, drive cam 5 and turn clockwise together, when flange 51 withstood galianconism 72, long-armed 71 around bearing pin 9 rotations and leave goods of furniture for display rather than for use 1, and this moment, goods of furniture for display rather than for use 1 was in the state that freely swings; Otherwise, when locking wheel 6 is counterclockwise rotated, driving cam 5 is rotated counterclockwise together, when flange 51 leaves galianconism 72, as shown in Figure 2, long-armed 71 under the effect of torsion spring 4 around bearing pin 9 rotation and hold goods of furniture for display rather than for use 1 tightly, this moment, goods of furniture for display rather than for use 1 was in locking state, because the effect of limited block 52 is held pawl 7 tightly and can not opened lock because of the acting force of goods of furniture for display rather than for use 1.Three enclasp devices 3 are held goods of furniture for display rather than for use 1 tightly simultaneously along circumference, make its centre that is in instrument inwall 2, and goods of furniture for display rather than for use 1 is not subjected to the effect of the side direction application of force, and promptly goods of furniture for display rather than for use 1 is locked in duty, thereby has protected instrument well.
Claims (6)
