[detailed description of the invention]
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Fig. 1 is the structure sectional view of lamp stand in an embodiment, the locking member structural representation of Fig. 2 to be the STRUCTURE DECOMPOSITION figure of lamp stand in an embodiment, Fig. 3 be lamp stand shown in Fig. 2.Composition graphs 1 to Fig. 3, this lamp stand comprises interior loop bar 100, outer loop bar 200 and locking and regulating device 300.Outer loop bar 200 hollow.Interior loop bar 100 is contained in outer loop bar 200, and relatively outer loop bar 200 can free reduction.Locking and regulating device 300 is connected with interior loop bar 100, is housed in outer loop bar 200, for interior loop bar 100 is positioned in outer loop bar 200, and loop bar 100 height in regulating.
Locking and regulating device 300 comprises and struts part 310, regulating part 320 and locking member 330.Strut part 310 to be connected with interior loop bar 100, regulating part 320 connection struts part 310 and locking member 330, and regulating part 320 regulates locking member 330 axially relatively to strut part 310 along outer loop bar 200 and moves.Locking member 330 has elasticity, and when locking member 330 moves to and struts part 310, strut part 310 and strut locking member 330, locking member 330 extrudes outer loop bar 200 and deformation occurs, and interior loop bar 100 is tightly fixed on outer loop bar 200 by free reduction status lock.
In this embodiment, strut part 310 in truncated cone-shaped, the bottom that radius is larger is fixedly connected with interior loop bar 100, and relative top is connected with regulating part 320.Strut part 310 basal diameter and be less than or equal to interior loop bar 100 external diameter.
Regulating part 320 comprises screw rod 321, adjusting nut 322 and jump ring 323.Screw rod 321 one end with strut part 310 top and be connected.Adjusting nut 322 and screw rod 321 adaptation are spirally connected, and adjusting nut 322 is reciprocating rotation on screw rod 321.Jump ring 323 is arranged in screw rod 321 other end, prevents adjusting nut 322 from being come off by screw rod 321.In a preferred embodiment, to be connected one end be threaded rod to screw rod 321 with strutting part 310, and screw rod 321 other end polished rod, does not have screw thread.
Locking member 330 is socketed on adjusting nut 322, and adjusting nut 322 drives locking member 330 to move on screw rod 321.Locking member 330 comprises locking plug 331 and cushion rubber 332.Composition graphs 3, locking plug 331 is two, is the semicircle column type of hollow, and split forms the cylinder of hollow, and is sheathed on adjusting nut 322.Adjusting nut 322 moves up and down on screw rod 321 by rotarily driving two locking plugs 331 on screw rod 321.Cushion rubber 332 is set in two locking plug 331 peripheries, locks two locking plugs 331.Locking plug 331 inner circumferential is provided with the nut groove 3311 for being socketed adjusting nut 322, and periphery is recessed to form the aprons slot 3312 holding cushion rubber 332.After the split of two locking plugs 331, cushion rubber 332 is set in the aprons slot 3312 of two locking plugs 331, is locked by two locking plugs 331, makes two to lock plug 331 and is not separated.Adjusting nut 322 by rotating on screw rod 321, regulate two to lock plug 331 to move up and down on screw rod 321, when two locking plugs 331 move to and strut part 310, strut part 310 two locking plugs 331 are strutted, two locking plugs 331 extrude outer loop bar 200 and deformation occur, thus are locked by interior loop bar 100.
Sectional view when Fig. 4 is the adjustment of lamp stand shown in Fig. 1 height, Fig. 5 is schematic diagram when lamp stand is fixed shown in Fig. 1.Sectional view when Fig. 6 is the use of lamp stand shown in Fig. 1.Composition graphs 1 to Fig. 6, in use, adjusting nut 322 is socketed on screw rod 321 this lamp stand, and jump ring 323 is located on screw rod 321, and locking member 330 is socketed on adjusting nut 322.First, turn interior loop bar 100, make adjusting nut 322 be positioned at the position of polished rod of screw rod 321, locking member 330 is in natural size, the free reduction in loop bar 200 outside of interior loop bar 100, as required by interior loop bar 100 outward loop bar 200 li be encased in proper height.Then, oppositely turn interior loop bar 100, turning in process, adjusting nut 322 drives locking plug 331 to move toward strutting direction, part 310 bottom surface, strut part 310 gradually two locking plugs 331 to be strutted, softened locking plug 331 and outer loop bar 200 close contact, be fixed on outer loop bar 200 by frictional force tightly by interior loop bar 100, do not slide, holding is carried out to bulb.When changing or keep in repair bulb, only need turn interior loop bar 100 and make locking member 330 return to natural size.Adjustment highly.This lamp stand becomes interior loop bar 100 and outer loop bar 200 from single lamp stand, and the fixing and release by locking and regulating device 300 of interior loop bar 100, be adjusted to outer loop bar 200 optional position, adjustment oneself height, is down to desired height by bulb, changes or maintenance bulb, safe, convenient, fast, carry out work high above the ground without the need to operator, avoid potential safety hazard, ensure that personal security.
In other embodiments, locking member comprises locking plug and cushion rubber.Locking plug be socketed with adjusting nut, and locking plug is the column type of hollow, and cylinder offers one vertically and through otch, and inner circumferential offers nut groove, and periphery offers aprons slot.When locking plug and being socketed with adjusting nut, first locking plug is pulled open with incision, then locking plug sleeve is connected on adjusting nut, finally cushion rubber is sheathed in aprons slot, locking locking plug.
Or regulating part comprises screw rod and jump ring, screw rod one end with strut part top and be connected, periphery is equipped with screw thread.Locking member comprises locking plug, and locking plug is the column type of hollow, is connected with screw flight, and locking is filled in one end relative with strutting part and had at least one opening vertically.Jump ring is arranged in the screw rod other end, prevents locking plug from coming off.Locking plug by screw motion to strutting part, by strut part strut to outer loop bar close contact, locking in loop bar.
In addition, be the interior loop bar that is locked further, this lamp stand also comprises locking pin, and locking pin runs through outer loop bar, is spirally connected with outer loop bar.Locking pin moves back and forth, locking and the interior loop bar of release.
Above-mentioned lamp stand, has interior loop bar and outer loop bar, and interior loop bar is by locking and regulating device outside loop bar are located, be in outer loop bar optional position, adjustment oneself height, when repairing or replacing bulb, is down to desired height by bulb, carry out changing or keeping in repair, substitute a traditional lamp stand, safe, convenient, fast, carry out work high above the ground without the need to operator, avoid potential safety hazard, ensure that personal security.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
