Abstract
A kind of lengthening connection mechanism of mop rod, wherein one section of pole is set as outer bar, one section of pole is set as interior bar, the end of the interior bar is equipped with connector, the connector is equipped with screw thread, and the side wall of the outer bar is equipped with the salient point to convex, and the connector screws in the outer bar, the salient point and the screw-thread fit, screw in the salient point in the screw thread.The utility model does not set plastic nut in metal outer bar, thus produce, assembling process it is all relatively simple, the easy to aging, problem that service life is low caused by plastic nut may be not present.
Description
Technical field
The utility model is related to a kind of lengthening connection mechanisms of mop rod.
Background technology
Mop board is usually made of several extension bar bodies, is connected by lengthening connection mechanism between the body of rod and the body of rod, to each
The integral mop rod of body of rod group.
The connection method of lengthening connection mechanism most original between the body of rod and the body of rod is after two sections of body of rod sockets are got up
It screws and follows closely or directly pressed after connecting by rivet, two sections of bodies of rod sockets are got up, its company of this original connection structure
The reliability connect is not high, and destruction to a certain extent can be formed to the body of rod.
In order to overcome the shortcomings of that above-mentioned original connection type, prior art generally use such as under type realize adding for mop rod
Long connection：Mop rod includes outer bar, interior bar, and the upper end of interior bar is set there are one plastic whorl section, and plastic whorl section is equipped with outer spiral shell
Line；It is set in outer bar there are one plastic nut, interior bar is selected into from the lower end of outer bar into outer bar, to plastic whorl section and plastic spiral
Screw-thread fit between mother.Its there is also the shortcomings that be：Plastic nut is fastened in outer bar, for plastic nut and outer bar
Dimensional fits it is more demanding, production, assembling process it is all complex；And the screw-thread fit between plastic nut and thread segment is not
Enough smooth, there is also the low problems of easy to aging, service life for plastic nut.
Invention content
In order to overcome existing mop rod lengthening connection mechanism above-mentioned deficiency, it is simpler that the utility model provides a kind of structure
The lengthening connection mechanism of easier mop rod is assembled in single, production.
The technical scheme in the invention for solving the technical problem is：A kind of lengthening connection mechanism of mop rod, wherein one
Section pole is set as outer bar, and one section of pole is set as interior bar, and the end of the interior bar is equipped with connector, is set on the connector
There are screw thread, the side wall of the outer bar to be equipped with the salient point to convex, the connector screws in the outer bar, the salient point
With the screw-thread fit, screwed in the salient point in the screw thread.
Further, the connector is plastics screw head, and the plastic spiral headgear is tightly in the end of the interior bar.Or
Person：The interior bar is metallic rod, and the side wall of the interior boom end extrudes the screw thread.
Further, the outer bar is metallic rod, and inside punching press is to convex described in formation on the side wall of the outer bar
Point.
Further, the screw thread is one start screw or multiple thread.
The beneficial effects of the utility model are：Plastic nut is not set in metal outer bar, therefore production, assembling process are all
It is relatively simple, the easy to aging, problem that service life is low caused by plastic nut may be not present.

Fig. 2 is the structural schematic diagram of the utility model for being equipped with disk mop.
Fig. 3 is the explosive view of the utility model when thread segment uses one start screw.
Fig. 4 is the sectional view of Fig. 3.
Fig. 5 is the partial enlarged view of part A in Fig. 4.
Fig. 6 is the explosive view of the utility model when thread segment uses double thread.
Fig. 7 is the explosive view of the utility model when thread segment uses three-start screw.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Referring to Fig.1 ~ Fig. 7, the lengthening connection mechanism of mop rod are applied on mop rod, which can be used for flat panel mop
Or disk mop, the lengthening connection mechanism of mop rod include metal outer bar 1, interior bar 2, the head of the interior bar 2 is equipped with screw thread
Section 3, the thread segment 3 are equipped with external screw thread, and the side wall of the metal outer bar 1 is equipped with the salient point 4 to convex, the salient point
4 coordinate with the external screw thread, and the interior bar 2 is screwed in from the lower end of the metal outer bar 1 in the metal outer bar 1, from
And the salient point 4 screws in the external screw thread so that link together between metal outer bar 1 and interior bar 2.The quantity of salient point
It can be configured according to actual needs, but at least need a salient point 4.
Certain thread segment can also be arranged in the tail portion of interior bar, and interior bar 2 screws in institute from the upper end of the metal outer bar 1 at this time
In the metal outer bar 1 stated.
In the present embodiment, the thread segment 3 is plastics screw head, and the plastic spiral headgear is tightly in the upper of the interior bar 2
End；To form the salient point 4, the formation of salient point 4 is simpler for inside punching press on the side wall of the metal outer bar 1.
Certainly, other modes may be used in the formation of thread segment 3, and example thread segment as mentioned is formed in the head of the interior bar
On portion's side wall, i.e., directly external screw thread is extruded on the head of the ontology of interior bar.
The external screw thread can be one start screw or multiple thread, as the external screw thread of thread segment 3 in Fig. 3 uses single head spiral shell
Line, the external screw thread of thread segment 3 uses double thread in Fig. 6, and the external screw thread of thread segment 3 uses three-start screw in Fig. 7.
