Background technique
When the length of mop rod, clothes-horse, besom bar etc. was longer, these poles had Telescopic usually, and existing expansion link uses telescoping tube as handle usually, and are fixing but telescoping tube is difficult for, and connect insecurely, use comparatively to bother.
The model utility content
The purpose of this utility model is to overcome above shortcomings in the prior art, and a kind of reasonable in design is provided, and is fixing simple, is connected firmly flexible rod bindiny mechanism easy to use.
The technical scheme in the invention for solving the above technical problem is: this connecting mechanism of expansion rod comprises the inner tube that sleeve pipe and caliber and sleeve pipe are complementary, its characteristics are: also comprise handle, with the location overcoat of locating hole, shape and size all with the positioning inner sleeve of locating overcoat and being complementary; An end that is fixed on sleeve pipe of described positioning inner sleeve, the other end of this positioning inner sleeve is provided with three to five lobe lobe bodies uniformly, described positioning inner sleeve and sleeve pipe all are set with on inner pipe, described location coat suit is on sleeve pipe, the locating hole that puts outside this location is for oval, and the structure of described handle is U-shaped, and this handle is hinged on the sleeve pipe by screw, described screw cross-under is in the locating hole of location overcoat, and the two ends of described handle all are arranged in the locating hole of location overcoat.
Lobe body number on the positioning inner sleeve described in the utility model other end is pintongs.
Positioning inner sleeve described in the utility model is fixed on the inwall of sleeve pipe.
Positioning inner sleeve described in the utility model is fixed on the outer wall of sleeve pipe.
The utility model compared with prior art, have the following advantages and effect: interior pipe cross-under in the location, overlap and sleeve pipe in, be provided with three to five lobe lobe bodies on one uniformly and have in the cover in the location, the lobe body that puts in the location can be clamped by the location overcoat, make the lobe body that puts in the location firmly anchor ear on the outer wall of interior pipe, thereby the locating function of pipe in sleeve pipe in realizing.
The utility model by carry on the handle or drop-down just can reach that the location overcoat moves down or on the purpose of moving, thereby the function of realization positioning inner sleeve anchor ear inner tube.
The utility model is simple in structure, and is easy to operate, and the connection between sleeve pipe and the interior pipe is fastening effective.
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation;
Fig. 2 is that the utility model embodiment removes the structural representation of shaking hands afterwards and carrying out decomposed;
Fig. 3 is the utility model embodiment's location overcoat and the structural representation that handle is installed in sleeve pipe;
Fig. 4 is that the utility model embodiment's location overcoat and handle is installed in the structural representation that analyse and observe sleeve pipe the back on the sleeve pipe.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Embodiment:
Referring to Fig. 1 to Fig. 4, connecting mechanism of expansion rod in the present embodiment is made up of sleeve pipe 1, location overcoat 2, positioning inner sleeve 3, inner tube 4,5 and two screws 6 of handle, its middle sleeve 1 mates mutually with the caliber of inner tube 4, sleeve pipe 1 can be sleeved on the inner tube 4, and the caliber of sleeve pipe 1 and inner tube 4 mutually mates and is prior art.The shape of location overcoat 2 and positioning inner sleeve 3 and size are also mated mutually.
Positioning inner sleeve 3 end that is fixed on sleeve pipe 1 in the present embodiment, and the outside wall surface of positioning inner sleeve 3 and sleeve pipe 1 fixes, and the positioning inner sleeve 3 in the utility model also can fix with the internal face of sleeve pipe 1.On the other end of positioning inner sleeve 3, be provided with uniformly pintongs lobe body, namely on the other end of positioning inner sleeve 3, be provided with uniformly four interspaces, and the other end that makes positioning inner sleeve 3 is lobe body shape, thereby guarantee that the caliber on positioning inner sleeve 3 other ends has zoom function, can under external force the pipe fitting of cross-under in positioning inner sleeve 3 be held firmly.Lobe body number in the utility model on positioning inner sleeve 3 other ends can arrange according to actual needs, usually between three to five lobes.
Be provided with two oval-shaped locating holes on the overcoat 2 of location in the present embodiment, this location overcoat 2 is sleeved on the sleeve pipe 1, the bottom of location overcoat 2 is set with mutually with the positioning inner sleeve 3 that is fixed on the sleeve pipe 1, the lobe body that just can realize on positioning inner sleeve 3 other ends by moving down of location overcoat 2 shrinks, and namely the caliber on positioning inner sleeve 3 other ends dwindles.Handle 5 in the present embodiment is U-shaped structure, and handle 5 is hinged on the sleeve pipe 1 by two screws 6, and two screws 6 cross-under are in two locating holes of location overcoat 2 respectively, the two ends of handle 5 also lay respectively in two locating holes of location overcoat.When on carry or under when pulling handle 5, the two ends of handle 5 can produce an active force to location overcoat 2, so that location overcoat 2 is round about mobile, as shaking hands 5 when upwards carrying, the two ends extruding of handle 5 is located overcoat 2 and location overcoat 2 is produced a downward active force, so that location overcoat 2 moves down.
Sleeve pipe 1 in the present embodiment and positioning inner sleeve 3 all are sleeved on the inner tube 4, when handle 5 when drop-down, shake hands 5 pairs to locate overcoats 2 and produce a power that moves up, so that location overcoat 2 moves on slightly along sleeve pipe 1, thereby so that being subjected to locating the extruding force of overcoat 2, the pintongs lobe body on the positioning inner sleeve 3 reduces, so that pintongs lobe body reduces the anchor ear power that inner tube 4 produces, inner tube 4 just can move in sleeve pipe 1 and positioning inner sleeve 3.On the contrary, when carrying on the handle 5, shake hands 5 pairs to locate overcoats 2 and produce a power that moves down, so that location overcoat 2 moves down slightly along sleeve pipe 1, pintongs lobe body on the positioning inner sleeve 3 is subjected to locating the extruding force increase of overcoat 2, so that pintongs lobe body increases the anchor ear power that inner tube 4 produces, inner tube 4 has just been suffered in positioning inner sleeve 3 by anchor ear firmly, thereby has realized good positioning function.
Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
