Detailed Description

Example (b):

referring to figures 1-5 of the drawings,

the injection needle for the livestock raising and the veterinary comprises a main body 1, a needle head 2 and a fixing component;

as shown in fig. 2, an ear plate 106 is arranged on the outer surface of a main body 1, a needle 2 is arranged on one side of the main body 1, limiting rods 201 are arranged on two sides of the needle 2, one end of each limiting rod 201 is connected with a fixing block 203 in a sliding manner, adjusting blocks 3 are arranged on the inner walls of two sides of the main body 1, an injection chamber 101 is arranged in the main body 1, a piston 102 is connected in the injection chamber 101 in a sliding manner, a push rod 103 is fixedly connected to one side of the piston 102, one end of the push rod 103 is fixedly connected with a push plate 104, an adjusting chamber 301 is arranged in the adjusting block 3, the fixing block 203 is positioned in the adjusting chamber 301, and one end of the fixing block 203 protrudes out of the outer surface of the main body 1;

the adjusting bin 301 is internally provided with a fixing component for limiting and clamping the needle head 2.

The main body 1 is made of polystyrene material, the polystyrene material has the characteristics of strong hardness, light transmission and the like, the main body 1 can load liquid medicine into the injection bin 101 in the using process, the main body 1 made of the polystyrene material can prevent the main body 1 from being damaged, the liquid medicine suction condition in the main body 1 can be observed due to the light transmission characteristic, and the amount of the liquid medicine is controlled;

as for the main body 1, polymethyl methacrylate material with the light transmission performance reaching 92% should be selected, and then polystyrene material with the light transmission performance only reaching 90% should be selected, which are two materials with better light transmission performance, but the manufacturing cost of the polymethyl methacrylate material is higher, so that the manufacturing cost of the main body 1 is too high, therefore, the polymethyl methacrylate material is not suitable for manufacturing the main body 1, the manufacturing cost of the same polystyrene material is lower, and the light transmission performance of the polystyrene material is also enough for checking the quantity of extracted liquid medicine.

Further, fixed subassembly includes interlock tooth 204 and cooperation tooth 302, be provided with a plurality of interlock tooth 204 on the surface of fixed block 203 one side, regulation bin 301 is provided with a plurality of cooperation tooth 302 on being close to the inner wall of syringe needle 2 one side, and interlock tooth 204 and cooperation tooth 302 interlock mutually, in the use, when the user need insert syringe needle 2 on the animal body, the user can take the finger on otic placode 106, and press from both sides two fingers, promote fixed block 203 and make it at the inside removal of regulation bin 301, extrude reset spring 303 and with interlock tooth 204 and cooperation tooth 302 card together, with this with syringe needle 2 fixed, prevent that syringe needle 2 rocks when the user need prick syringe needle 2 on the animal body and leads to the condition emergence that is difficult to pierce the epidermis.

Further, the inside movable groove of having seted up of fixed block 203, be provided with stopper 205 on the inner wall of movable groove both sides, spacing groove 202 has been seted up to gag lever post 201 both sides, and stopper 205 and spacing groove 202 sliding connection, in the use, when interlock tooth 204 on fixed block 203 and cooperation tooth 302 were mutually meshed, fixed block 203 will not be able to rotate, block in spacing groove 202 through stopper 205 this moment, make fixed block 203 also limit gag lever post 201, and then fix syringe needle 2, prevent its rotation.

Further, fixed block 203 one side is provided with reset spring 303, the gag lever post 201 surface is located to reset spring 303 cover, and the inner wall fixed connection of reset spring 303 other end and surge bin 301, when the user inserts syringe needle 2 and begins to inject on the animal, can loosen the centre gripping of finger to fixed block 203, fixed block 203 will move in the direction of keeping away from cooperation tooth 302 under reset spring 303's promotion, with this separate interlock tooth 204 and cooperation tooth 302, relieve the block to fixed block 203, and then relieve the restriction to syringe needle 2, syringe needle 2 can be at main part 1 with this rotation of carrying out the freedom this moment, when the animal struggled by the injection, syringe needle 2 also can rotate along with struggling of animal, avoid the animal to struggle the in-process and leave the condition emergence of syringe needle 2 rupture in the animal.

Further, the opening has been seted up to main part 1 one side, be provided with a plurality of cardboard 105 on the push rod 103 surface, and cardboard 105 is connected with the opening block, in the use, the user promotes push rod 103 through push pedal 104 and drives piston 102 and inside the sliding of injection storehouse 101, with this with the inside liquid medicine injection precession animal in the injection storehouse 101 internal, in the promotion in-process, push rod 103 rocks when the block through the opening to cardboard 105 can prevent that the user from promoting push rod 103, cause the condition that the liquid medicine of piston 102 perk is revealed to take place.

Further, 2 one end fixedly connected with draught tube 107 of syringe needle, inside the draught tube 107 other end inserts injection storehouse 101, when the user promoted piston 102 and carries out the in-process that the medicine was injected, the liquid medicine reaches 2 insides of syringe needle through draught tube 107, injects the animal in again, links up through draught tube 107 and can supply liquid that the in-process of syringe needle 2 pivoted also can be incessant.

Furthermore, an inclined plane is arranged on one side of the needle head 2, the inclination angle of the inclined plane is 15-30 degrees, the contact surface between the needle head 2 and the animal epidermis can be reduced through the inclination angle, so that the pressure of the needle head 2 when a user inserts the needle head 2 is improved, the user can conveniently insert the needle head 2 on the animal epidermis, and the use convenience is improved.

When the utility model is used, firstly, a user needs to prick the needle 2 into a liquid medicine bottle, partial liquid medicine is pumped into the injection bin 101, the animal can be injected, the user can put fingers on the ear plate 106 and clamp the two fingers, the fixing block 203 is pushed to move in the adjusting bin 301, the reset spring 303 is squeezed and the biting tooth 204 and the matching tooth 302 are clamped together, so that the needle 2 is fixed, the situation that the epidermis is difficult to puncture due to the shaking of the needle 2 when the user needs to prick the needle 2 on the animal is prevented, after the needle 2 is fixed, the needle 2 is stuck on the epidermis of the animal, the needle 2 is inserted on the animal, when the needle 2 is inserted on the animal, the clamping of the fixing block 203 by the fingers can be released, the fixing block 203 moves in the direction far away from the matching tooth 302 under the pushing of the reset spring 303, so as to separate the biting tooth 204 and the matching tooth 302, the clamping of the fixing block 203 is released, and then the limitation of the needle 2 is released, at the moment, the needle 2 can freely rotate in the main body 1, when an injected animal struggles, the needle 2 can also rotate along with the struggle of the animal, the situation that the needle 2 is broken and left in the animal body in the animal struggling process is avoided, the injection can be started after the limitation of the needle is untied, a user can push the push rod 103 to drive the piston 102 to slide in the injection cabin 101 through the push plate 104, so that the liquid medicine in the injection cabin 101 is injected into the animal body, in the pushing process, the clamping of the clamping plate 105 through the opening can prevent the push rod 103 from shaking when the user pushes the push rod 103, the situation that the piston 102 tilts the liquid medicine to be leaked is caused, the liquid medicine reaches the inside of the needle 2 through the flow pipe 107 and is injected into the animal body again, the liquid can be supplied uninterruptedly in the rotating process of the needle 2 through the connection of the flow pipe 107, therefore, the device can provide convenient and practical liquid medicine injection function for users through the structure.
