Abstract
The utility model discloses a fine adjustment needle cylinder comprising a valve sleeve, a needle head, a valve needle, a valve drum and a flow control hole. The valve sleeve and the valve drum are fastened through fixed connection. The valve drum is provided with a valve drum head. The valve needle is arranged inside the valve drum. The needle head is arranged on one side of the valve needle, and a valve cap is arranged on the other side of the valve needle. A needle hole fitting the needle head is arranged on the valve sleeve. The flow control hole is arranged in the valve drum head. The fine adjustment needle cylinder achieves fine adjustment and guarantees precision simultaneously. The fine adjustment needle cylinder is simple in structure, stable and reliable, and has a self-locking function.
Description
Technical field
The utility model relates to a kind of syringe of finely tuning realized.
Background technology
The surface of conventional syringes is provided with scale, when needs repeatedly use same a kind of liquid in different time sections, and when the dosage needs are accurate, in most cases the staff is by rule of thumb with feel, can work as dosage when very little, it is just not much of that to depend experience and feel alone, and this just needs a kind of syringe that can keep accurate dosage output.
Summary of the invention
The utility model purpose: the purpose of this utility model is in order to solve the deficiencies in the prior art, and a kind of syringe of finely tuning realized is provided, and has guaranteed precision when having realized fine setting, and is simple in structure, has auto-lock function and reliable and stable.
Technical scheme: in order to realize above purpose, a kind of syringe of finely tuning realized described in the utility model, it comprises valve pocket, syringe needle, needle, valve cylinder and flow control hole, described valve pocket is fastening by captiveing joint with valve cylinder, and described valve cylinder is provided with the valve cylinder head, is provided with needle in the described valve cylinder, one side of described needle is provided with syringe needle, the opposite side of needle is provided with bonnet, and described valve pocket is provided with the pin hole that matches with syringe needle, and described flow control hole is located on the valve cylinder head.
Described valve pocket, syringe needle, needle and valve cylinder are on same axis.
Described needle and valve cylinder are realized fixing by internal and external threads.
Flow control hole links to each other with flow-controlling gate.
Needle and valve cylinder are in transmission connection by screw thread, can extrapolate the number of turns of bonnet rotation by the dosage of needs output, behind the bonnet of rotating valve Aculeata, the rotatablely moving of needle turns and drives syringe needle and carry out traveling priority, input required liquid by flow-controlling gate in flow control hole, this liquid is exported by pin hole, and the syringe needle on the needle will constantly enter into pin hole along with the rotation of bonnet, when the inclined-plane on the syringe needle withstands pin hole, stop output liquid.
Beneficial effect: the utility model provides a kind of syringe of finely tuning realized, simple in structure, the dosage that can export as required rotates the number of turns of bonnet, thereby realizes the fine setting of dosage, and dosage is accurate, can realize self-locking, and is reliable and stable.
Description of drawings
Fig. 1 is semisectional view of the present utility model;
Fig. 2 is the front view of needle;
Fig. 3 is the cutaway view of valve pocket.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate the utility model.
Shown in Figure 3 such as Fig. 1 Fig. 2, the utility model comprises: valve pocket 1, syringe needle 2, needle 3, valve cylinder 4 and flow control hole 5, described valve pocket 1 is fastening by captiveing joint with valve cylinder 4, described valve cylinder 4 is provided with valve cylinder head 6, be provided with needle 3 in the described valve cylinder 4, a side of described needle 3 is provided with syringe needle 2, and the opposite side of needle 3 is provided with bonnet 8, described valve pocket 1 is provided with the pin hole 7 that matches with syringe needle 2, and the described flow control hole that links to each other with flow-controlling gate 5 is located on the valve cylinder head 6.
Described valve pocket 1, syringe needle 2, needle 3 and valve cylinder 4 are on same axis.
Described needle 3 and valve cylinder 4 are realized fixing by internal and external threads.
The utility model provides a kind of syringe of finely tuning realized, simple in structure, syringe needle 2 is done traveling priority under the drive of the gyroscopic movement of needle 3, can know that by the number of the helix line on the needle 3 nut 8 needs the number of turns of rotating, thereby realization dosage is finely tuned accurately, realize fixingly by internal and external threads because of needle 3 and valve cylinder 4, so this syringe can realize self-locking, and reliable and stable.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model Spirit Essence all should be encompassed within the protection domain of the present utility model.
