Abstract
The utility model relates to a sucker head of a novel film-making dyeing machine. The sucker head comprises a hollow tubular body, wherein the lower end of the tubular body is sleeved with a sucker; the middle of the tubular body is sleeved with a sucker withdrawing sleeve in a sliding manner; a circle of stressed baffle ring is arranged at the upper end surface of the sucker; the sucker withdrawing sleeve props against the stressed baffle ring of the sucker when the tubular body slides to the lowest end. The sucker head has the beneficial effects that a structure of sealing connection of the sealing ring is adopted for a groove in the sucker, and as an O-shaped rubber sealing ring has the characteristic of elastic deformation, gas or liquid leakage is avoided; moreover, the tubular body of the sucker head and the sucker can be solidly connected and are not easy to drop off automatically; meanwhile, the sucker can be more easily pushed and disassociated because of the sucker withdrawing sleeve; due to adoption of corresponding structures of the sealing ring and the sucker groove, the sucker can be more easily inserted, the height of the inserted sucker can be kept accordant, the requirement on machining precision of a conical part of the tail end of the tubular body can be reduced, and as the sealing ring is low in cost and easy to replace, the manufacturing and maintenance cost is effectively lowered.
Description
Technical field
The utility model belongs to the accessory of dyeing machine, is specifically related to a kind of suction nozzle head of novel dyeing machine.
Background technology
Cell preparation staining machine all can adopt disposable suction nozzle transfer liquid, thereby avoids sample cross pollution, in use, needs a kind of suction nozzle head unit repeatedly to insert to get and discharges disposable suction nozzle.Being arranged in the market the suction nozzle of cell preparation staining machine is all that tubular metal, end are the structures of tapering as first, and tapering part firmly contacts and is connected with suction nozzle, to reach the effect that connects and seal.In actual use due to the otherness of suction nozzle, the abrasion deformation of tapering part, insert the reasons such as the dynamics of getting and the degree of depth; capital has a strong impact on being connected and sealing reliability of suction nozzle head and suction nozzle, often there will be and does not get suction nozzle, the suction nozzle faults such as dropping liquid that come off, leak gas.Therefore, be necessary to provide a kind of novel suction nozzle head to overcome defect and the problem of above-mentioned existence.
Summary of the invention
The utility model, in order to solve the technical matters of mentioning in background technology, provides a kind of suction nozzle head of novel dyeing machine.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of suction nozzle head of novel dyeing machine, the tubular body that comprises a hollow, the lower end of tubular body is set with suction nozzle, one of the medium position slip suit of tubular body moves back muzzle, the upper surface of suction nozzle is provided with the stressed back-up ring of a circle, moves back muzzle when tubular body slides into bottom outward and the stressed back-up ring of suction nozzle offsets.
The lower end periphery of tubular body is provided with some circle grooves, and every circle groove is all set with a circle O RunddichtringO, and suction nozzle is tightly connected by the lower end of O RunddichtringO and tubular body.
The lower end of tubular body is lower young pyramidal structure, and the lower end structure of suction nozzle and tubular body is with respect to being taper.
Move back muzzle and be provided with a circle installation back-up ring outward.
The lower end periphery of tubular body is provided with two circle grooves.
The beneficial effects of the utility model are: the structure that adopts O-ring seal to be tightly connected for the groove on suction nozzle.Because O type rubber seal has the characteristic of elastic deformation, so can seal reliably, avoid the dropping liquid that leaks gas; And tubular body and the suction nozzle that can firmly connect suction nozzle head, be difficult for self falling; Meanwhile, move back muzzle and more easily evade suction nozzle.Due to the counter structure of O-ring seal and suction nozzle groove, make to insert that to get suction nozzle easier, contraposition is more accurate, and inserting the height of getting suction nozzle can be consistent.The requirement on machining accuracy that can also reduce tubular body end tapering part, O-ring seal is with low cost, easily changes, and effectively reduces and manufactures and maintenance cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the stressed back-up ring of the utility model Fig. 1.
Embodiment
Referring to Fig. 1, Fig. 2, a kind of suction nozzle head of novel dyeing machine, the tubular body 1 that comprises a hollow, the lower end of tubular body 1 is set with suction nozzle 2, one of the medium position slip suit of tubular body 1 moves back muzzle 3, the upper surface of suction nozzle 2 is provided with the stressed back-up ring 4 of a circle, moves back muzzle 3 while sliding into bottom and the stressed back-up ring 4 of suction nozzle 2 offsets outside tubular body 1.
For all parts of the present utility model, explain:
1) the lower end periphery of tubular body 1 is provided with some circle grooves 5, and every circle groove 5 is all set with a circle O RunddichtringO 6, and suction nozzle 2 is tightly connected by O RunddichtringO 6 and the lower end of tubular body 1.
2) lower end of tubular body 1 is lower young pyramidal structure, and the lower end structure of suction nozzle 2 and tubular body 1 is with respect to being taper.
3) move back the outer circle that is provided with of muzzle 3 back-up ring 7 is installed.
4) the lower end periphery of tubular body 1 is provided with two circle grooves 5.
The beneficial effects of the utility model are: the structure that adopts O-ring seal to be tightly connected for the groove on suction nozzle.Because O type rubber seal has the characteristic of elastic deformation, so can seal reliably, avoid the dropping liquid that leaks gas; And tubular body and the suction nozzle that can firmly connect suction nozzle head, be difficult for self falling; Meanwhile, move back muzzle and more easily evade suction nozzle.Due to the counter structure of O-ring seal and suction nozzle groove, make to insert that to get suction nozzle easier, contraposition is more accurate, and inserting the height of getting suction nozzle can be consistent.The requirement on machining accuracy that can also reduce tubular body end tapering part, O-ring seal is with low cost, easily changes, and effectively reduces and manufactures and maintenance cost.
