Description
Technical field
The utility model relates to lifting positioning field, especially a kind of lift locating device.
Background technology
Elevating lever is a kind of widely used adjustable for height telescoping rod, and be generally used for the occasion that some need to regulate height, such as some outdoor illuminating lamps just need to use elevating lever; Existing elevating lever utilizes locking nut to lock, positioned-lifting bar, level altitude; Locking screw easily loosens, and affects elevating lever location; The anti-rotation of elevating lever mainly ensures by the frictional force of each parts, poor stability, and rotation can make locking nut loosen, and affects elevating lever location; And need to twist off locking nut to remove location when regulating highly, operating difficulties, uses inconvenience; This kind ofly can prevent elevating lever from rotating with regard to needing and the lifting arm localization mechanism of effective location can solve these problems.
Utility model content
The utility model aims to provide a kind of lift locating device effectively preventing elevating lever from rotating.
For achieving the above object, the utility model provides following technical scheme: lift locating device, comprise A fixed leg, B fixed leg, depression bar, tooth bar, teeth, locking member, locking member control valve, spring and spring stop, described B fixed leg is set in A fixed leg, A fixed leg is provided with tooth bar, described locking member is sleeved on B fixed leg, and locking member is provided with teeth; Described locking member control valve is sleeved on locking member inside; Described locking member control valve inside is provided with spring, and top is provided with depression bar, and it is inner that depression bar is set in B fixed leg, and described spring bottom is provided with spring stop.
Preferably, described locking member control valve entirety is truncated cone-shaped.
Preferably, described spring stop is fixedly connected with locking member.
Compared with prior art, the beneficial effects of the utility model are: this lift locating device, by the position of mobile locking member control valve, the teeth on locking member are made to be in the two states opening and shrink, engage with the tooth bar on B fixed leg, locate the position of B fixed leg with this, can effectively prevent B fixed leg from rotating simultaneously, ensure position stability; Regulate during adjustable height and only by certain mode, locking member control valve need be moved, make teeth be in contraction state, just can remove location, otherwise apply location, regulate the position of B fixed bar, simple to operate, easy to use.
Accompanying drawing explanation
Fig. 1 is overall schematic of the present utility model;
Fig. 2 is the A place enlarged drawing of Fig. 1;
Fig. 3 is sectional view of the present utility model;
Fig. 4 is the A place enlarged drawing of Fig. 3.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-4, in the utility model embodiment, lift locating device, comprises A fixed leg 1, B fixed leg 2, depression bar 3, tooth bar 4, teeth 5, locking member 6, locking member control valve 7, spring 8 and spring stop 9; Described B fixed leg 2 is set in A fixed leg 1, and A fixed leg 1 is provided with tooth bar 4, and described locking member 6 is sleeved on B fixed leg 2, and locking member 6 is provided with teeth 5, and teeth 5 and tooth bar 4 engage and be used for fixed retaining member 6; It is inner that described locking member control valve 7 is sleeved on locking member 6, and locking member control valve 7 entirety is truncated cone-shaped; Described locking member control valve 7 inside is provided with spring 8, top is provided with depression bar 3, it is inner that depression bar 3 is set in B fixed leg 2, spring stop 9 is provided with bottom described spring 8, spring stop 9 is fixedly connected with locking member 6, play the effect stopping spring 8, make locking member control valve 7 be limited in locking member 6 inner, locking member control valve 7 is in the state extruded to locking member 6 under the effect of spring 8; Now, the dual-side of locking member 6 is expanded laterally because being subject to the extruding of locking member control valve 7, so just use be positioned at locking member 6 side teeth 5 stretch out laterally, just withstand the tooth bar 4 on opposite, thus play the effect of location.When removing positioning action, apply pressure to locking member control valve 7 by depression bar 3, spring 8 is compressed, and locking member control valve 7 pressurized state is removed, and locking member 6 resets, thus makes teeth 5 exit tooth bar 4, and positioning action is removed.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should by description integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
