Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
Referring to fig. 1-8, the present invention provides a technical solution:
the first embodiment is as follows: an electronic syringe needle convenient for connection comprises an empty barrel 1. The inner side of the hollow cylinder 1 is connected with a piston shaft 3 in a sliding mode, the front end face of the piston shaft 3 is fixedly connected with a piston handle 4, the front end face of the piston shaft 3 is fixedly connected with a piston 5, and the piston 5 is connected with the hollow cylinder 1 in a sliding mode. The middle part of the rear end of the hollow cylinder 1 is communicated with an injection head 7, the rear end of the injection head 7 is in interference fit with a pintle 8, and the rear end of the piston 5 is provided with an electronic stroke controller 27. The rear end face of the pintle 8 is fixedly connected with a fixed disk 9, and the middle part of the fixed disk 9 is in interference fit with the needle stem 2. The back end of the needle stalk 2 is provided with a needle tip 6, and the outer side of the front end of the needle stalk 2 is fixedly connected with a sealing ring 28.
The rear end face of the fixed disc 9 is uniformly and fixedly connected with fixed blocks 10, and the end faces, close to each other, of the fixed blocks 10 are fixedly connected with sliding rods 11. The slide bar 11 is externally connected with a rack 12 in a sliding way. The middle of the rack 12 is provided with a sliding chute 13, the inside of the sliding chute 13 is connected with a sliding column 14 in a sliding manner, the rear end face of the sliding column 14 is fixedly connected with a clamping rod 16, and the outer side of the clamping rod 16 is connected with an L-shaped rod 15 in a sliding manner. The front end face of the L-shaped rod 15 is fixedly connected with a fixed disc 9, the end faces, close to each other, of the clamping rods 16 are fixedly connected with a V-shaped block 17, the V-shaped block 17 is connected with a needle stem 2 in a sliding mode, and the racks 12 are connected with a gear ring 18 in a meshed mode. The front end surface of the gear ring 18 is rotationally connected with a fixed disc 9.
The middle part of the left end face of the left side rack 12 is fixedly connected with a thread block 21, the middle part of the thread block 21 is in threaded connection with a threaded rod 19, the lower end face of the threaded rod 19 is rotatably connected with a supporting block 20, and the front end face of the supporting block 20 is fixedly connected with a fixed disc 9. By inserting the needle stem 2 into the middle of the fixed disk 9 and then rotating the threaded rod 19, the threaded rod 19 drives the left rack 12 to move through the threaded block 21. The gear ring 18 rotates, the three racks 12 move simultaneously, the sliding column 14 slides in the sliding groove 13, the clamping rods 16 are close to each other, and the needle bar 2 is clamped by the V-shaped block 17 to be fixed. When needing to dismantle, as long as reverse rotation threaded rod 19, clamping rod 16 keeps away from each other, can with needle stalk 2 take off to be more convenient for accomplish the installation and dismantle needle stalk 2 and fixed disk 9, and then be more convenient for accomodate needle stalk 2 alone.
Example two: the difference of this embodiment and embodiment one lies in, wherein, empty 1 right side middle part interference fit of section of thick bamboo has grafting post 22, and grafting post 22 right-hand member front side sliding connection has block pole 24, and 24 front end sliding connection of block pole have L type piece 25, and L type piece 25 left end face downside fixedly connected with empty 1 of section of thick bamboo, 24 lower extreme left end face fixedly connected with pressure spring 26 of block pole, pressure spring 26 left end fixedly connected with empty 1 of section of thick bamboo, grafting post 22 rear end face fixedly connected with lag 23. The protecting sleeve 23 is inserted into the rear end of the hollow cylinder 1 through the inserting column 22, then the pressure spring 26 is pulled, and the clamping rod 24 is inserted into the inserting column 22 to complete fixation, so that the protecting sleeve 23 is more conveniently installed at the rear end of the hollow cylinder 1, and a protecting effect is further achieved on the needle stem 2 and the needle point 6.
When the needle bar fixing device works, firstly, the needle bar 2 is inserted in the middle of the fixing disc 9, then the threaded rod 19 is rotated, and the threaded rod 19 drives the left rack 12 to move through the threaded block 21. The gear ring 18 rotates, the three racks 12 move simultaneously, the sliding column 14 slides in the sliding groove 13, the clamping rods 16 are close to each other, and the needle bar 2 is clamped by the V-shaped block 17 to be fixed.
When needing to dismantle, as long as reverse rotation threaded rod 19, clamping rod 16 keeps away from each other, can take off needle stalk 2, accomodate when placing, peg graft protective sheath 23 in empty section of thick bamboo 1 rear end through grafting post 22, then pulling pressure spring 26, it is fixed to accomplish in grafting post 22 with block rod 24 grafting, and protective sheath 23 plays a guard action to needle stalk 2 and needle point 6. The whole device is formed by inserting the needle stalk 2 into the middle of the fixed disk 9 and then rotating the threaded rod 19. The threaded rod 19 drives the left rack 12 to move through the threaded block 21, the gear ring 18 rotates, the three racks 12 move simultaneously, the sliding column 14 slides in the sliding groove 13, the clamping rods 16 are close to each other, and the needle stem 2 is clamped by the V-shaped block 17 to be fixed. When needing to dismantle, as long as reverse rotation threaded rod 19, clamping rod 16 keeps away from each other, can with needle stalk 2 take off to be more convenient for accomplish the installation and dismantle needle stalk 2 and fixed disk 9, and then be more convenient for accomodate needle stalk 2 alone. The protecting sleeve 23 is inserted into the rear end of the hollow cylinder 1 through the inserting column 22, then the pressure spring 26 is pulled, and the clamping rod 24 is inserted into the inserting column 22 to complete fixation, so that the protecting sleeve 23 is more conveniently installed at the rear end of the hollow cylinder 1, and a protecting effect is further achieved on the needle stem 2 and the needle point 6.
