Abstract
The utility model relates to a toothbrush capable of accurately positioning an inserting port which helps to resolve problems that a brush head and a brush handle of a conventional toothbrush with the replaceable brush head are instable in installation, inaccurate in positioning and easy in abrasion, and a connecting port is short in service lifetime. The toothbrush is characterized in that positioning fixture blocks are arranged on pins; the positioning fixture blocks and the pins are of integral structures; one end of each spring sleeves on each positioning fixture block which is just matched with each spring to ensure stability of each pin and each spring; and one end of each spring abuts against each pin and the other end of each spring abuts against the inner wall of a handle port. The toothbrush capable of accurately positioning the inserting port has following beneficial effects: when the brush head is inserted into a groove in port part, the pins do not shake as a connecting block at the bottom of the brush head and the pins are positioned due to the fact that springs sleeve on the positioning fixture blocks; positioning operation is carried out stably and accurately; and in use, the brush head and the handle well combined as a whole and do not shake or swing.
Description
Technical field
The utility model relates to a kind of toothbrush, is specifically related to the toothbrush of a kind of accurate location socket.
Background technology
Toothbrush is the normal instrument using in people's daily life, for the effect of oral cavity cleaning and tooth, and elongated along with service time, head toothbrushes usually can lose clean effect, so people will throw away whole toothbrush, the toothbrush then more renewing.Yet toothbrush is normally made by plastics, change frequently whole toothbrush, can cause the white pollution of environment, very unfavorable to protection of the environment.
China Patent No.: CN201563874U discloses a kind of toothbrush, comprises brush and handle, and both are connected with the cooperation of draw-in groove by pin, have so just realized the effect of replaceable brush head.
But spring one end of this patent just props up pin, make when brush inserts, spring may teetertotter, and causes the location inaccuracy of pin and draw-in groove, so brush and brush holder are installed unstable.
Utility model content
In order to overcome the deficiency of background technology, the utility model provides the toothbrush of a kind of accurate location socket, has mainly solved brush and the brush holder of existing brush toothbrush with replaceable, installs unstablely, locates coarse problem.
The technical scheme that the utility model adopts is the toothbrush of a kind of accurate location socket, comprise brush, brush holder and the interface unit that connects brush brush holder, in described interface unit, be provided with groove, described brush bottom is provided with the contiguous block matching with this groove, described groove both sides are provided with pin-and-hole, and described pin-and-hole protrudes from groove inwall, in pin-and-hole, be provided with pin, in described interface unit, be also provided with two spring eyes vertical with pin-and-hole, in this spring eye, be provided with spring, described contiguous block is provided with the draw-in groove blocking mutually with pin, described pin is provided with positioning wedged block, this positioning wedged block and pin are integral type structure, described spring one end is sheathed on this positioning wedged block, and this positioning wedged block is just suitable mutually with spring, described spring one end and described pin offset, the other end and handle inwall offset.
Described positioning wedged block is columniform bayonet lock, and the diameter of cylinder is consistent with the internal diameter of spring.
The side of described pin is arc surface, and the bottom margin of described contiguous block is suitable arc surface.
Described interface unit bottom is provided with boss, and described brush holder top is provided with the installation cavity that holds this interface unit and boss, in described boss, is provided with screwed hole, is provided with corresponding screw in described installation cavity.
The beneficial effects of the utility model are: owing to taking technique scheme, when brush is inserted in the groove of interface unit, because spring housing is located on positioning wedged block, when the contiguous block of brush bottom and finger setting, pin can not rock, and makes the stable of location, accurately, in use, brush and handle well become one, and can not produce and rock and wave.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A place enlarged drawing in Fig. 1.
Fig. 3 is the exploded view of interface unit in Fig. 1.
Fig. 4 is the top view of Fig. 3.
In figure 1, brush; 11, contiguous block; 2, brush holder; 21, installation cavity; 3, interface unit; 31, groove; 32, pin-and-hole; 33, pin; 34, spring eye; 35, spring; 36, positioning wedged block; 4, boss; 41, screwed hole.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Figure 1-Figure 4, the toothbrush of a kind of accurate location socket, comprise brush 1, brush holder 2 and the interface unit 3 that connects brush brush holder, in described interface unit 3, be provided with groove 31, described brush 1 bottom is provided with the contiguous block 11 matching with this groove 31, described groove 31 both sides are provided with pin-and-hole 32, and described pin-and-hole 32 protrudes from groove 31 inwalls, in pin-and-hole 32, be provided with pin 33, in described interface unit 3, be also provided with two spring eyes vertical with pin-and-hole 32 34, in this spring eye 34, be provided with spring 35, described contiguous block 11 is provided with the draw-in groove 12 blocking mutually with pin, described pin 33 is provided with positioning wedged block 36, this positioning wedged block 36 is integral type structure with pin 33, described spring 35 one end are sheathed on this positioning wedged block 36, and this positioning wedged block 36 is just suitable mutually with spring 35, described spring 35 one end and described pin 33 offset, the other end and handle 2 inwalls offset.
Described positioning wedged block 36 is columniform bayonet lock, and the diameter of cylinder is consistent with the internal diameter of spring 35.Certainly, positioning wedged block 36 not only limits to cylindrical, also can be for putting shape, and when cylinder, the internal diameter of diameter and spring 35 is consistent just can suppress to sell 33 teetertotter; When being square, square four angles and spring 35 inside offset, and also can play same effect.The utility model is preferably columniform bayonet lock.
The side of described pin 33 is arc surface, and the bottom margin of described contiguous block 11 is suitable arc surface.When both are arc surface, in both engagement process, can reduce certain resistance, for coordinating, strengthen stability.
