Description
Technical field
The utility model relates to a kind of water pump.Specifically, the pump chamber connection securing means linked together by vertical water pump cavity is used to.
Background technique
All know at water pump production industry, the vertical water pump for high rise building water supply is stacked by multiple modular pump to form.Wherein, the cavity of each unit water pump must link together in stacking shape.Conventional attachment methods is arranging two screw rods in the cavity surrounding stacking shape, all there is plush copper two screw rods lower end, the surrounding of described pump seat and pump head is all processed with two rod aperture, after described two screw rods upper end is each passed through two rod aperture pump seat below described pump seat, stretch out on pump head after being each passed through two rod aperture on pump head again, the external part of its two screw rods is all processed with screw thread and is furnished with nut.By screw on nut, can realize carrying out fastening to multiple cavity stacked together.Although adopt, can to realize between multiple cavity in this way fastening, and owing to needing the screw rod of through whole housing depth, the steel not only needed are more, and cost of production is high, and screw rod protrudes in cavity surrounding, very unsightly.Again owing to only having two screw rods, cavity surrounding unbalance stress, easily produces skew, makes the sealing effect between cavity poor, thus causes the leakage of water pump.
Model utility content
Problem to be solved in the utility model is to provide a kind of pump chamber connection securing means.This pump chamber connection securing means, use steel few, cost of production is low, attractive in appearance.Adopt this pump chamber connection securing means, good sealing effect between cavity, water pump leak case can be avoided to occur.
The problems referred to above to be solved in the utility model are realized by following technological scheme:
Pump chamber connection securing means of the present utility model comprises pump head and at least two cavitys, and described pump head is short cylinder, and its sidewall has water outlet, and there is flange plate at its two ends respectively.Described cavity is cylindrical and stacks together, and be characterized in that the flange plate circumference of described pump head lower end has axis hole, all have pull bar in axis hole, there is screw thread pull bar upper end is furnished with nut.Described cavity surrounding has steel band, and steel band quantity is equal with pull bar, and steel band upper end links together with corresponding pull bar lower end respectively.All there is interior crotch described steel band lower end, and described interior crotch is hooked on that cavity bottom edge undermost.
Wherein, described that cavity lower end undermost is uncovered shape, and described interior crotch is hooked on that oral area edge, cavity lower end undermost.
The cross section of described steel band is circular arc, and the cylindrical radian of its radian and described cavity is suitable.
Take such scheme, have the following advantages:
As can be seen from the above scheme, because the flange plate circumference of described pump head lower end is processed with axis hole, all have pull bar in axis hole, there is screw thread pull bar upper end is furnished with nut.Described cavity surrounding has steel band, and steel band quantity is equal with pull bar, and steel band upper end links together with corresponding pull bar lower end respectively.All there is interior crotch described steel band lower end, and described interior crotch is hooked on that cavity bottom edge undermost.The locking mechanism utilizing the parts such as several short rod and steel band to form, just can realize fixing between multiple cavity.Compared with the conventional method in background technique, not only can save steel, reduce cost of production, and very attractive in appearance.Adopt this pump chamber connection securing means, good sealing effect between cavity, thus the generation avoiding water pump leak case.
Accompanying drawing explanation
Fig. 1 is pump chamber connection securing means schematic diagram of the present utility model;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Embodiment
As depicted in figs. 1 and 2, pump chamber connection securing means of the present utility model comprises pump head 5 and 12 cavitys 3, and described pump head 5 is short cylinder, and its sidewall is processed with water outlet 4, its two ends are processed with flange plate 6 respectively.Described cavity 3 is cylindrical and 12 cavitys 3 and stacks together.The flange plate 6 circumference processing four of described pump head 5 lower end has axis hole, and these four axis holes are along the circumferential direction uniform.All be furnished with pull bar 8 in described axis hole, pull bar 8 upper end is processed with screw thread and is furnished with nut 7.Described cavity 3 surrounding is provided with four steel bands 2, and steel band 2 upper end welds together with corresponding pull bar 8 lower end respectively.The cross section of described steel band 2 is circular arc, and the cylindrical radian of its radian and described cavity 3 is suitable.Described steel band 2 lower end is all processed with interior crotch 1, and described interior crotch 1 is all hooked in that cavity 3 bottom sides undermost along upper.
Wherein, that cavity lower end undermost is uncovered shape, and described interior crotch is hooked on that oral area edge, cavity lower end undermost.
