Description
Technical field
The utility model relates to the technical field of vacuum pump, refers in particular to a kind of improved medical gas ring vacuum pump.
Background technique
The gas ring vacuum pump of conventional medical industry, the output shaft of its outputting power is generally positioned at the front end of the pump housing (being pump cover end), reaches the object of installation by being fixed on pump cover, thus the power output that vacuum pump can be produced is used for medical equipment.Because the pump cover of vacuum pump is not generally offered mounting hole, in the time that output shaft needs outputting power, need pump cover to process, the newly-increased through hole mating with output shaft can use.Due to the repeatedly processing of pump cover, by the increase that first causes cost of production to drop into; Secondly mate with output shaft owing to a through hole need to being offered in the center of pump cover, need to transform for existing pump cover, procedure complexity, is unfavorable for the comprehensive production of product.
Summary of the invention
The utility model provides a kind of improved medical gas ring vacuum pump for the problem of prior art, this medical gas ring vacuum pump stretches out motor fan housing after the rotor shaft of drive motor is lengthened, and is directly connected with medical equipment as output shaft, and procedure is simple, easy to assembly, practical.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of improved medical gas ring vacuum pump, include the pump housing and drive motor that coupling connects, the front-end face of the described pump housing is provided with pump cover, described drive motor is provided with motor fan housing, described drive motor is equipped with rotor shaft, one end of described rotor shaft is connected with pump cover, and the other end of described rotor shaft is fixedly connected with and passes motor fan housing with motor fan housing.
Wherein, one end that described rotor shaft stretches out motor fan housing is provided with screw thread.
Further, also include base, the cross section of described base is " V " type, and the described pump housing is installed in " V " type groove of base.
Wherein, the described pump housing is fixedly connected with base through screws.
The beneficial effects of the utility model:
The utility model provides a kind of improved medical gas ring vacuum pump, by lengthening the rotor shaft of drive motor, its one end is connected with pump cover, and stretching out motor fan housing, the other end can be connected with medical equipment as output shaft, form respectively balance pivot at two ends, not only can ensure the stressed even, not yielding of rotor shaft, effectively strengthen working life; And the utility model offers for pump cover the through hole mating with rotor shaft specially without the pump cover end at the pump housing, break through traditional fixed installation pattern, thereby made the utility model procedure simple, easy to assembly, practical.
Brief description of the drawings

Embodiment
For the ease of those skilled in the art's understanding, below in conjunction with embodiment and accompanying drawing, the utility model is further described, the content that mode of execution is mentioned is not to restriction of the present utility model.
Referring to Fig. 1 to Fig. 2, below in conjunction with accompanying drawing, the utility model is described in detail.
The improved medical gas ring vacuum pump of one described in the utility model, include the pump housing 1 and drive motor 2 that coupling connects, the front-end face of the described pump housing 1 is provided with pump cover 11, described drive motor 2 is provided with motor fan housing 21, described drive motor 2 is equipped with rotor shaft 3, one end of described rotor shaft 3 is connected with pump cover 11, and the other end of described rotor shaft 3 is fixedly connected with and passes motor fan housing 21 with motor fan housing 21.
The utility model provides a kind of improved medical gas ring vacuum pump, by lengthening the rotor shaft 3 of drive motor 2, its one end is connected with pump cover 11, and stretching out motor fan housing 21, the other end can be connected with medical equipment as output shaft, form respectively balance pivot at two ends, thereby ensure the stressed even, not yielding of rotor shaft 3, effectively strengthen working life; All offer through hole 211 because whether motor fan housing 21 center needs to stretch out rotor shaft 3, therefore in the time that rotor shaft 3 of the present utility model is fixed as output shaft and medical equipment, the utility model offers for pump cover 11 through hole 211 mating with rotor shaft 3 specially without pump cover 11 ends at the pump housing 1, break through traditional fixed installation pattern, thereby make the utility model procedure simple, easy to assembly, practical.
In the utility model, one end that described rotor shaft 3 stretches out motor fan housing 21 is provided with screw thread 31.In the time that rotor shaft 3 is connected with outside medical equipment, the screw thread 31 that stretches out one end of motor fan housing 21 by rotor shaft 3 carries out screw thread 31 with medical equipment and is connected, disassembly and assembly are all very convenient, and good stability, effectively strengthened practicability of the present utility model.
Further, also include base 4, the cross section of described base 4 is " V " type, and the described pump housing 1 is installed in " V " type groove 41 of base 4.In the utility model, the bottom of the described pump housing 1 is provided with base 4, because the cross section of base 4 is " V " type, the pump housing 1 directly can be installed in this " V " type groove 41, not only the pump housing 1 is played the effect of support, can also play fixing effect to the pump housing 1, effectively avoid the pump housing 1 to occur rocking in the time of work, strengthen stability of the present utility model.
In the utility model, the described pump housing 1 is fixedly connected with by screw 42 with base 4.In the time that the described pump housing 1 is installed on base 4, by the pump housing 1 and base 4 use screws 42 are locked, can further strengthens the pump housing 1 and be installed on the stability of base 4, thereby effectively strengthen practicability of the present utility model.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
