Chopsticks with changeable head

The utility model is a kind of tableware that mainly is made of timber and two kinds of materials of plastics, especially a kind ofly can save timber, the Chopsticks with changeable head that has the disposable hygienic function again in a large number.

Chopsticks with changeable head in my patent application for the first time is made up of connecting in turn the connecting tube and the chopsticks of wooden chopstick head, plastics.The chopsticks handle can be wooden, bamboo matter or plastics.Chopstick head, chopsticks all are made into the bolt shape structure to the part that plays anastomosis, and connecting tube is made into the nut type structure, and the screw thread on the bolt and the screw thread on the nut must guarantee identical closely each other.Chopstick head, chopsticks are screwed into the part that plays anastomosis by separately respectively and finish connection in the connecting tube from the two ends of connecting tube.When changing chopstick head, earlier old chopstick head is screwed down from connecting tube, chopsticks are screwed on new chopstick head after sterilization again.As seen, the draw bail of this Chopsticks with changeable head is loaded down with trivial details and complicated, bother very much to making production manufacture them, and it is also convenient inadequately to change chopstick head.

The purpose of this utility model provides a kind of Chopsticks with changeable head, and it not only has disposable hygienic function and can save the advantage of timber, and has more to produce and manufacture that they are easy and change chopstick head advantage easily.

The utility model by chopstick head wooden, function of use for once and plastics, reusable chopsticks repeatedly connect two parts and form.Chopsticks directly are made into connecting tube to the part that plays anastomosis, only need 2 draw points of installing in connecting tube; And chopstick head plays the part of anastomosis and does not do special processing and handle, and still keeps original pole shape structure to get final product.2 draw points thrust the chopstick head that injects in the connecting tube, and chopstick head is finished connecting with chopsticks.When changing chopstick head, only need old chopstick head from chopsticks pulling up, chopsticks are plugged after sterilizing new chopstick head just passable again.

As seen: the draw bail of this Chopsticks with changeable head is more simple, and production is manufactured very easy, and in use, it is convenient especially to change chopstick head.

Below in conjunction with accompanying drawing with execute example the utility model is specified.

Fig. 1, be the vertical section structural map of chopstick head, chopsticks handle.

Fig. 2, be that chopstick head, chopsticks are the vertical section structural map that connects good Chopsticks with changeable head.

Fig. 3, be the cross section structural map of connecting tube.

Among the figure 1, chopstick head and mouth and the contacted part of food, be called for short: contact site

2, chopstick head plays the part of anastomosis, is called for short: connection part

3, draw point

4, chopsticks are the connecting tube of front end

5, the portion of the handle of chopsticks handle is called for short: the Handheld Division

Chopstick head is wooden, is pole shape structure, and its diameter is 4.5 millimeters, and it is function of use for once.Long 8 centimetres of the contact site of chopstick head (1), if herein less than 8 centimetres, in the use, mouth and food are run into connecting tube (4) easily, to making the utility model lose wholesomeness one time; If herein greater than 8 centimetres, can cause timber too much to waste.The connection part of chopstick head (2) is long 1.5 centimetres, and is if herein less than 1.5 centimetres, should not chopstick head firm with connecting of chopsticks handle; If herein greater than 1.5 centimetres, can cause timber too much to waste equally.

Long 14 centimetres of the portion of the handle of chopsticks handle (5), its outer surface is decorated various pattern, and purpose is to make Chopsticks with changeable head attractive in appearance, can allow the user be ready to accept.Chopsticks equal the length of chopstick head connection part (2) to long 1.5 centimetres of the connecting tube of front end (4), and its internal diameter is 4.6 millimeters, and pipe thickness is 1 millimeter.2 thicknesses of connecting tube (4) the inside installing and family stitch No. 3 pins that clothing uses similar, length is 6 millimeters draw point (3).The part that 2 draw points are fixed on inside the Handheld Division (5) is connected into one, constitutes " U " shape structure.This structure helps 2 draw points installs in Handheld Division (5) firmly, can effectively resist and pull out when changing chopstick head and the strength of inserting, and prolongs the service life of whole chopsticks handle.2 draw points are with the internal diameter trisection of connecting tube (4).Because draw point (3) is thinner, so it can not split the chopstick head thorn that inserts connecting tube; Since the length of draw point (3) surpass connecting tube length half promptly do not surpass 7.5 millimeters, so when chopstick head and chopsticks when connecting, chopstick head is difficult slotting inclined to one side; In addition, the quantity of draw point is 2, this just guaranteed chopstick head and chopsticks between to connect dynamics enough big, when having avoided the use Chopsticks with changeable head to have meal chopstick head from chopsticks coming off.2 more effective chopstick heads that prevented of draw points rotate on the chopsticks handle simultaneously.

When using the utility model, new chopstick head is inserted chopsticks in the connecting tube of front end (4), at this moment, the draw point (3) in the connecting tube (4) also thrusts the connection part (2) of chopstick head simultaneously, and chopstick head, chopsticks become one promptly connecting, and constitute Chopsticks with changeable head.After the meal, with old chopstick head from chopsticks pulling up, do not re-use.And chopsticks are sterile-processed also reusable.When chopsticks can not make the degree of wear it normally connect with chopstick head again, when perhaps its outer surface degree of wear can not be ready to accept by the user, it can be reclaimed, be processed into new chopsticks handle again.
