Embodiment
See Fig. 1 and 2, show telescopic positioning device of the present utility model.
Described telescopic positioning device comprises fixed block 10 and extension member 11, described fixed block 10 is provided with the chute 101 carrying out elastic movement for extension member 11, in the drawings, described fixed block 10 contains extension member 11, what those skilled in the art were known is, fixed block 10 also can not contain extension member 11, chute 101 can be the open trough of one end open, to be applicable to different mechanisms, fixed block can be formed as the parts relative to not movement in various mechanism, and extension member is formed as the parts needing telescopic moving, the utility model can be assemblied in different extending meanss.
Wherein, described extension member 11 is provided with multiple spaced locating slot 111, and described multiple locating slot 111 is parallel to telescopic direction, and span also can regulate according to the needs of location.
Described fixed block 10 is provided with by gland 12, describedly be installed on fixed block 10 by gland 12 by multiple assembly department 121 being arranged at bight, optionally, described assembly department 121 is provided with the through hole run through for screw, the corresponding screw be provided with for screw fastening on described fixed block 10, describedly be provided with locating piece 13 by gland 12, see Fig. 3 and Fig. 4, described locating piece 13 is rectangular sheet and comprises superposed press part 131 and the press part 132 being positioned at bottom, the lower end of described locating piece 13 is extended with positioning part 133 downwards, described fixed block 10 is provided with the perforation running through to insert a wherein locating slot 111 for positioning part 133, described by being provided with button 122 and spring 123 in gland 12, the bottom of described button 122 is resisted against described press part 131, top stretches out from the through hole by gland 12, and the lower end of button 122 is provided with flange to avoid deviating from from by gland 12, the bottom of described spring 123 is resisted against described press part 132, top is resisted against the lower surface by gland 12, described fixed block 10 is provided with the projection 125 being resisted against locating piece 13 middle lower surface between button 122 and spring 123.
Thus, under normal conditions, spring 123 is by the press part 132 of elastic force against locating piece 13, thus force positioning part 133 through the perforation of fixed block 10 and be inserted in the wherein locating slot 111 on extension member 11, at this moment location can be formed, and once need telescopic moving, by pushing button 122, the lower end abutment press part 131 of button 122 also overcomes the elastic force of spring 123 by lever principle, the positioning part 133 of locating piece 13 is driven upwards to lift, deviate from from locating slot 111, thus extension member 11 can carry out telescopic slide by opposed fixed member 10, until move to the position location of needs, unclamp button again, re-start location, not only this structure simple but also laborsaving.
Wherein, for avoiding loosening and moving of spring, also can be provided with guide rod 124, described spring 123 is wound in guide rod 124 outer rim to avoid loosening of spring, described guide rod 124 can be arranged at by gland 12 or fixed block 10, by suitable mode be fixed and keep-spring two ends against.
Wherein, see Fig. 5 and Fig. 6, show the different structure in another embodiment of the utility model, for realizing two-way location, locating slot 11 can be set to the rectangular recess in Fig. 1-2, thus provide former and later two directions against location, no matter be stretch forward or backward, button is all needed to carry out lifting and could move, and in order to realize unidirectional location, the locating slot 112 that also can arrange in Fig. 5-6 is dovetail groove, namely the straight trough 1121 of side and the skewed slot 1122 of opposite side is comprised, needing the direction of location, straight trough 1121 is set, thus formed to positioning part 133 against, not needing the direction of locating, skewed slot 1122 is set, skewed slot 1122 is provided with the inclined-plane can deviate from for positioning part 133, thus unidirectional movement can be carried out by direct pull extension member 11 without the need to pressing keys, unidirectional flexible location can be realized thus.
Wherein, described in by the protection projection 126 that gland 12 also can be provided with protection button 122, the height of described protection protruding 126 stretches out equal or slightly high by the height of gland 12 with button 122, and protection protruding 126 is provided with receiving groove 127 and presses button for pointing.
Wherein, locating piece 13 can be the high-strength materials such as steel and makes, and described button is made by plastics, and described spring is helical spring.
As can be seen here, the utility model has the advantage of:
1, structure is simple, easy to operate, can realize the flexible location of single-direction and dual-direction;
2, accurate positioning, the cooperation of positioning part and locating slot avoids loosening.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present utility model, application or use.Although described in an embodiment and be described in the drawings embodiment, but the utility model do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present utility model, scope of the present utility model will comprise any embodiment of specification and the appended claim fallen into above.
