The utility model relates to a kind of non-return sucking heads, it includes attracting tube body, the mounting groove being arranged on aspirator tube body, the closure being arranged in mounting groove and the plectrum for blocking top being arranged in, it has been disposed radially through-hole in the closure, plectrum has been stirred and realizes that closure rotates in mounting groove；The utility model has the closure of through-hole by placing in mounting groove, stirs its rotation by plectrum, when through-hole direction attracts the channel of tube body, channel connection, negative pressure is realized on the head of sucking head, and when the channel of through-hole and attraction tube body is staggered completely, channel is closed.When needing to attract, it is entirely avoided the case where needing operator's whole process to press through-hole uses convenient for operator, improves working efficiency.
Description
Technical field
The utility model relates to a kind of non-return sucking heads.
Background technique
Aspirator is common instrument in current operation or medical procedure, can be used for attracting liquid or other impurities, is inhaled
Leader is connected to negative tube, is attracted using negative pressure, and current aspirator is that through-hole is arranged in the side of tube body mostly, is not made
With under state, it is connected to inside through-hole and sucking head, sucking action will not be generated.When being attracted, operator is needed
Through-hole is blocked with finger, just suction function can be generated on the head of sucking head at this time and be attracted, this requires that must have
One finger is motionless, blocks through-hole always, will limit the operation of operator in this way, causes inconvenient to use.
Utility model content
The technical problem to be solved by the utility model is to provide one kind can realize sucking head opening and closing by stirring plectrum
Non-return sucking head.
The technical scheme adopted by the utility model is a kind of non-return sucking head comprising tube body, setting is attracted to inhale
Mounting groove on skirt body, the closure being arranged in mounting groove and the plectrum for blocking top, the edge in the closure are set
It has been arranged radially through-hole, plectrum has been stirred and realizes that closure rotates in mounting groove.
Mounting groove described in the utility model is arranged radially along attraction tube body, the bottom of closure and the bottom connection of mounting groove
Touching, is provided with the sealing plate for being connected with mounting groove at the top of closure.
The utility model is provided with connecting column at the top of the closure, and connecting column passes through sealing plate, the plectrum setting
On the top of connecting column.
The utility model is provided with sealing ring at the position that the side wall of the upper and lower ends of the closure is contacted with mounting groove.
The utility model is provided with the annular groove for placing sealing ring in the upper and lower ends of the closure.
The utility model is provided with the plucking piece for stirring plectrum rotation on the attraction tube body.
Plucking piece described in the utility model include be slidably connected be arranged in attract tube body on sliding block and be arranged in cunning
The shift fork contacted inside block with plectrum, the position of the shift fork is corresponding with plectrum position, and plectrum is located at two groups of legs of shift fork
Between.
The utility model is provided with recessing groove with connecting column corresponding position inside the sliding block.
The good effect of the utility model are as follows: the utility model has the closure of through-hole by placing in mounting groove, leads to
It crosses plectrum and stirs its rotation, when through-hole direction attracts the channel of tube body, channel connection realizes negative pressure on the head of sucking head,
When the channel of through-hole and attraction tube body is staggered completely, channel is closed.When needing to attract, it is entirely avoided need operator
It the case where whole process pressing through-hole, is used convenient for operator, improves working efficiency.

Specific embodiment
As shown in attached drawing 1-5, the utility model includes attracting tube body 1, setting the operator hand-held part on attracting tube body 1
The mounting groove 6 of position, the closure 7 being arranged in mounting groove 6 and the plectrum 3 that 7 tops of closure are set by connecting column 2, in institute
It states and has been disposed radially through-hole 5 in closure 7, attracting the channel 9 having in tube body 1 for attraction, mounting groove 6 is provided with channel 9
On, it stirs plectrum 3 and realizes to block and 7 rotated in mounting groove 6, when through-hole 5 is towards channel 9, realize head and the company of sucking head
The negative tube connection for attracting tube body 1 is connect, realizes the vacuum suction on head, when through-hole 5 is staggered completely with channel 9, sucking head
Head and negative tube disconnect, and lose suction function.The aperture for adjusting through-hole 5 Yu channel 9 simultaneously, can not change negative tube pressure
The suction that sucking head is adjusted in the case where power, keeps operator more convenient to use, quick.
The mounting groove 6 blocks 7 bottom and the bottom connection of mounting groove 6 touches along being arranged radially for tube body 1 is attracted,
The top for blocking 7 is provided with the sealing plate 4 for being connected with mounting groove 6.
The position that the upper and lower ends of the closure 7 are contacted with mounting groove 6 is provided with sealing ring, in the upper of the closure 7
Lower both ends are provided with the annular groove 8 for placing sealing ring, improve the seal degree blocked between 7 and mounting groove 6, reduce deflation
Phenomenon.
As shown in Figures 6, 7, the plucking piece for stirring the rotation of plectrum 3 is provided on the attraction tube body 1, it is described
Plucking piece includes being slidably connected the sliding block 10 being arranged in attract on tube body 1 and setting is contacted in the inside of sliding block 10 with plectrum 3
Shift fork 12, the position of the shift fork 12 is corresponding with 3 position of plectrum, and plectrum 3 is located at two of shift fork 12 and dials between legs, in institute
It states 10 inside of sliding block and 2 corresponding position of connecting column is provided with recessing groove 11.By pushing sliding block 10 that shift fork 12 is made to drive plectrum 3
Rotation, thus when block deflection, realize the opening and closing of sucking head.
Above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although referring to aforementioned reality
Example is applied the utility model is described in detail, those skilled in the art should understand that: it still can be to preceding
Technical solution documented by embodiment is stated to modify or equivalent replacement of some of the technical features；And these are repaired
Change or replaces, the spirit and scope for the utility model embodiment technical solution that it does not separate the essence of the corresponding technical solution.
