Abstract

The utility model relates to a daily connecting-rod combining structure, belonging to the field of a daily household article and solving the problems that the existing mops, hangers, brooms, and the like have difficultly-regulated rod length and are not easily received and stored, the connecting part of a connecting rod combining part is easily loosened and is not firm, and the connecting rod combining part is not beautiful. The daily connecting-rod combining structure has the advantages that the rod length is easily regulated, the structure is easily received and stored, the connecting part of the connecting rod combining part is not easily loosened and is firm, and the connecting rod combining part is beautiful. The daily connecting-rod combining structure comprises a socket, an expansion head, a spiral groove and a spiral head. The utility model is characterized in that the socket is a circular hollow groove, and the expansion head is a hollow cylindrical structure the diameter of which is smaller than that of the socket. The lower half part of the expansion head is provided with four longitudinal openings, and the spiral groove is positioned at the hollow part of the inner side of the expansion head and is a helical groove. The spiral head is a cylinder the top end of which is provided with a spiral raised line matched with the spiral groove. The daily connecting-rod combining structure has the advantages of simple structure, reasonable design and obvious function and is suitable for people for promotion and using.

Description

Daily connecting rod assembly structure

Technical field

The utility model relates to a kind of bar linkage structure, belongs to daily family article field.

Background technique

In people's daily life, the bar portion of daily instruments such as mop, clothes hanger, bar broom always can face the not enough problem of length, if adopt long bar portion, can be not easy to take in storage again, so split type jointed connecting rod structure is arisen at the historic moment, but the bound fraction of existing split type jointed connecting rod structure all is to adopt insert-type sleeve-connected, or screw thread is twisted the mode that connects, these modes in use for some time, it is loosening that connection part will take place, problem such as insecure, and outward appearance neither be very attractive in appearance.

The model utility content

In order to overcome the bad adjusting of bar minister degree of existing mop, clothes hanger, bar broom etc., not easily contained storage, it is loosening that connection part takes place easily in the connecting rod connecting part, insecure, inaesthetic deficiency, the purpose of this utility model is: provide a kind of bar minister degree to regulate well, easily contained storage, it is loosening that the connecting rod connecting part is difficult for that connection part takes place, firmly, and daily connecting rod assembly structure attractive in appearance.

The technological scheme that its technical problem that solves the utility model adopts is as follows: a kind of daily connecting rod assembly structure, comprise socket, expansion-head, spiral chute, spiral head, described socket is circular hollow groove, expansion-head is the diameter hollow columnar body structure more young than socket, be positioned at socket inside, expansion-head lower half portion has 2-6 bar longitudinal opening, spiral chute is positioned at the inboard hollow space of expansion-head, be helical groove, spiral head be the top have can with the cylindrical body of the spiral burr of spiral chute coupling.

Described expansion-head lower half portion longitudinal opening quantity is 4.

Also comprise sleeving connecting rod, described sleeving connecting rod and socket link together.

Also comprise inserted link, described inserted link and spiral head link together.

In use, spiral head is inserted into socket inside, be connected and begin with expansion-head and tighten, the opening of expansion-head lower half portion begins expansion, makes the side of expansion-head and socket fluid-tight engagement together, reaches the purpose that is fastenedly connected, only need spiral head is returned stubborn during dismounting, expansion-head is shunk, and the space occurs between expansion-head and socket, can extract.

Compared with prior art, the beneficial effects of the utility model are:

1. adopt split modular structure with joint with uses that combine of two connecting rods, enough length is arranged during use, finish using and be convenient to take in storage after dismantling.

2. expansion-head and socket are combined closely, and make the connection of connecting rod enough firm, and aging produce loosening can not take place.

3. present technique connecting rod socket parts all place socket inside, make jointing more smoothly complete, and aesthetics greatly improves.

Description of drawings

Fig. 1 is the structural representation of the daily connecting rod assembly structure of the utility model.

Embodiment

Below in conjunction with drawings and Examples the utility model is further specified, but not as to qualification of the present utility model.

See also the embodiment of the daily connecting rod assembly structure of the utility model shown in Figure 1.

Embodiment

A kind of daily connecting rod assembly structure, comprise socket 1, expansion-head 2, spiral chute 3, spiral head 4, described socket 1 is circular hollow groove, the expansion-head 2 hollow columnar body structure littler that be diameter than socket 1, be positioned at socket 1 inside, expansion-head 2 lower half portions have 4 longitudinal openings, and spiral chute 3 is positioned at expansion-head 2 inboard hollow spaces, be helical groove, spiral head 4 for the top have can with the cylindrical body of the spiral burr of spiral chute 3 coupling.

Also comprise sleeving connecting rod 5, sleeving connecting rod 5 links together with socket 1.

Also comprise inserted link 6, inserted link 6 links together with spiral head 4.

Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
