Detailed Description

The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.

The collection barrel for picking up the insulin pen type syringe needle comprises a barrel body 1, a cover body A2, a pressing plate 3, a locking pin 4, a clamping assembly 5 and a tightening sleeve 7, wherein the cover body A2 is arranged on the top wall of the barrel body 1, the cover body A2 is fixedly connected with the barrel body 1 through screws, a barrel body 52 of the clamping assembly 5 is arranged in a through hole in the middle of the cover body A2, at least two circles of arc-shaped grooves 53 are formed in the outer circumference of the middle of the barrel body 52 at different heights, the locking pin 4 is fixed to the lower side of the cover body A2 through the pressing plate 3, the locking pin 4 is symmetrically distributed around the through hole in the middle of the cover body A2, the arc end of a central pin 44 on the locking pin 4 is arranged in one circle of the arc-shaped grooves 53, two groups of symmetrical notches are formed in the lower portion of the barrel body 52, the upper ends of the four elastic sheets 54 are fixedly connected with the barrel body 52 at the notches respectively, the lower ends of the four elastic sheets 54 are in a horn shape, clamping claws 55 are fixedly arranged on the inner wall of the lower end of each elastic sheet 54, the outer portion of the barrel body 52 is also sleeved with the tightening sleeve 7, the locking.

The locking pin 4 further comprises a fixing screw 41, a spring 42 and a shell 43, the center pin 44 is in a two-stage stepped shaft shape, the small end of the center pin 44 penetrates through one end of the shell 43 and is in clearance fit with a through hole at the end of the shell 43, and the large end of the center pin 44 is arranged in the shell 43; the other end of the housing 43 is fixedly connected to the fixing screw 41 by a screw, and a spring 42 is further provided between the center pin 44 and the fixing screw 41.

A ring 51 is fixedly arranged on the outer side of the top end of the cylinder 52; the elastic sheet 54 is a spring steel belt, and the holding claw 55 is a rubber strip. The tightening sleeve 7 and the pressing plate 3 are integrally formed. The barrel body 1 can be in the shape of a cylinder, a cube or a cuboid.

The outer wall of the barrel 52 is also provided with an anti-rotation rib 56, and the inner wall of the through hole in the middle of the cover A2 is provided with a clamping groove matched with the anti-rotation rib 56; without the anti-rotation ribs 56, one hand would grasp the barrel 52 and the other hand would rotate to unscrew the needle; the addition of anti-rotation ribs 56 prevents barrel 52 from rotating when the needle is manually turned for removal. The outer wall of the lower end of the cylinder 52 is also fixedly provided with a limiting block 57. The user is restricted from pulling the cartridge body 52 out of the through hole of the cover body a 2.

The locking pin 4 provided on the cover a2 locks the cylinder 52 in the clamping assembly 5 in a pre-tightening position or a clamping position, that is, when the center pin 44 of the locking pin 4 is snapped into the upper arc-shaped groove 53 on the outer wall of the cylinder 52, the tightening sleeve 7 does not tighten the lower ends of the four elastic pieces 54. At this time, if the pen-type injector is inserted into the barrel 52, the clasping claws 55 on the inner walls of the four elastic sheets 54 can provide a certain pretightening force for the needle of the pen-type injector, and the pretightening force provided can not only prevent the pen-type injector from falling naturally, and facilitate the lifting of the barrel 52 by an operator, but also prompt the operator that the needle of the injector reaches the corresponding positions of the clasping claws 55.

When the utility model is actually used, the cover body A2 and all parts mounted on the cover body A2 are mounted on the barrel body 1, and the center pin 44 of the locking pin 4 is clamped into the upper ring arc-shaped groove 53 on the outer wall of the barrel body 52; the injector which needs to unscrew the needle head is inserted into the cylinder body 52, the needle head is pre-tightened by utilizing the holding claws 55 on the inner walls of the four elastic sheets 54, the cylinder body 52 is manually lifted, the central pin 44 of the locking pin 4 retracts due to the contraction and extrusion, and when the lower circle arc-shaped groove 53 on the outer wall of the cylinder body 52 is opposite to the central pin 44, the central pin 44 is clamped into the lower circle arc-shaped groove 53 on the outer wall of the cylinder body 52 under the action of the spring. The central pin 44 of the locking pin 4 locks the cylinder 52 in the clamping position, and after the cylinder 52 moves upwards, the tightening sleeve 7 tightens the lower ends of the four elastic sheets 54, namely, the clasping claws 55 clamp the needle of the injector, and the needle is screwed off by manually rotating the pen injector. The barrel 52 is pressed downwards, so that the central pin 44 of the locking pin 4 is clamped in the upper arc-shaped groove 53 on the outer wall of the barrel 52, the clamping claws 55 on the inner walls of the four elastic sheets 54 are in a pre-tightening state, and the needle head taken down from the pen-type injector cannot naturally fall; at this time, the removed needle head can be pushed down by the slender strip-shaped object to drop in the barrel body 1, or a pen-type injector needing to unscrew the needle head can be pushed down, then the needle head of the pen-type injector needing to unscrew the needle head is pre-tightened, and then the operation of removing the needle head is repeated.

The utility model locks the cylinder in the clamping component at the pre-tightening position or the clamping position through the locking pin arranged on the cover body A, and the holding claw on the inner wall of the lower end of the elastic sheet realizes pre-tightening or clamping the needle head of the pen type injector; when the lower end of the elastic sheet is tightened up by the tightening sleeve, the holding claw clamps the needle head, and the needle head is screwed off by manual rotation, so that the utility model not only solves the problem that the exposed needle head is directly discarded in the garbage can, but also solves the problems that the needle head is not easy to take and is easy to stab when the needle head is taken; the utility model discloses no matter well hold the claw tightly and be in pretension state or press from both sides tight state, this internal syringe needle of bucket can not fall out, and fill the back at the bucket body, can take off reuse with lid A2, cover with ordinary lid B8 and unify the processing with the syringe needle after good, reduce the pollution to the environment as far as possible.
