Abstract
The utility model relates to a kind of water pump anti-reverse mechanism, comprise the ratchet cover plate, straight pin and water pump coupler, the described ratchet cover plate is fixed on the motor rack of water pump, and the pump shaft of water pump is through its core wheel, described water pump coupler is connected with the pump shaft of water pump and is provided with pin-and-hole on described water pump coupler, one end of described straight pin is movably arranged in described pin-and-hole, the other end of described straight pin is mounted on a surface of the described ratchet cover plate, and the surface of the described ratchet cover plate is provided with several ratchets.This water pump anti-reverse mechanism can only move up and down along ratchet plane of inclination from low to high according to the surface that straight pin is being provided with ratchet, once reverse, straight pin is namely stuck by the groove position of ratchet, thus realizes automatic anti-reverse and turn, without the need to manual control, and it is simple and compact for structure, working surface is little, thus reduces amount of finish, improves manufacturing efficiency, lower to the requirement of installing, be convenient to inspection and maintenance.
Description
Technical field
The utility model relates to a kind of anti-reverse mechanism, particularly relates to a kind of water pump anti-reverse mechanism.
Background technique
Some equipment such as water pump generally all require only to rotate towards a direction, be easy to burn out the pump housing, therefore just need some devices to reverse to prevent it if there is reversion.The main following two kinds of structural types of existing anti-reverse mechanism: the first arranges butterfly valve at rising pipe, butterfly valve is divided into Hand-operated butterfly valve and electric butterfly valve two kinds, and Hand-operated butterfly valve inconvenient operation, is unfavorable for the automatic management of whole machine set system, electric butterfly valve operability is good, but high cost; Another kind arranges anti-reverse mechanism on motor, but greatly can increase motor weight and size like this and cost is higher.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of water pump anti-reverse mechanism, make it have more value in industry.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of water pump anti-reverse mechanism, can automatically prevent reversion without the need to manual control, and simple and compact for structure, reduces water pump assembly overall dimensions.
The water pump anti-reverse mechanism that the utility model proposes, comprise the ratchet cover plate, straight pin and water pump coupler, the described ratchet cover plate is fixed on the motor rack of water pump, and the pump shaft of water pump is through its core wheel, described water pump coupler is connected with the pump shaft of water pump and is provided with pin-and-hole on described water pump coupler, one end of described straight pin is movably arranged in described pin-and-hole, and the other end of described straight pin is mounted on a surface of the described ratchet cover plate, and the surface of the described ratchet cover plate is provided with several ratchets.
Further, the described ratchet cover plate comprises interior wheel and foreign steamer, and the other end of described straight pin is mounted on described interior outer surface of taking turns.
Further, the ratchet on described ratchet cover plate surface is along pump shaft sense of rotation loop distribution from low to high, and the other end of described straight pin moves up and down along the inclined surface of ratchet.
Further, described water pump coupler is relatively set with two straight pins.
By such scheme, the utility model at least has the following advantages: this water pump anti-reverse mechanism can only move up and down along ratchet face from low to high according to the surface that straight pin is being provided with ratchet, once reverse, straight pin is namely stuck by the groove position of ratchet, thus realize automatic anti-reverse and turn, without the need to manual control, and simple and compact for structure, and working surface is little, thus minimizing amount of finish, improve manufacturing efficiency, lower to the requirement of installing, be convenient to inspection and maintenance.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
Accompanying drawing explanation
Fig. 1 is the side view of the utility model using state;
Fig. 2 is the front view of the ratchet cover plate;
Fig. 3 is ratchet center circle unfolded drawing.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See shown in Fig. 1 to 3, a kind of water pump anti-reverse mechanism described in the utility model one preferred embodiment, comprises the ratchet cover plate 1, straight pin 2 and water pump coupler 3.The ratchet cover plate 1 is fixed on the motor rack 5 of water pump, and the pump shaft of water pump is through its core wheel, and the ratchet cover plate 1 comprises interiorly takes turns 11 and foreign steamer 12.Water pump coupler 3 is connected with the pump shaft of water pump and is relatively set with two pin-and-holes 4 on described water pump coupler 3, be respectively equipped with two straight pins 2, one end of straight pin 2 is movably arranged in pin-and-hole 4, the other end is mounted on the outer surface of wheel 11 in the ratchet cover plate 1, this outer surface is provided with several ratchets, and in the present embodiment, the quantity of ratchet is six, ratchet is along pump shaft sense of rotation loop distribution from low to high, and the other end of straight pin 2 moves up and down along the inclined surface of ratchet.And ratchet height is 8mm.
When water pump coupler 3 rotates; straight pin 2 rotates with water pump coupler 3; one end that straight pin 2 stretches in pin-and-hole 4 is collected together up and down in pin-and-hole 4; when water pump normally runs; straight pin 2 the other end moves up and down along the inclined surface of the ratchet on wheel 11 outer surfaces in the ratchet cover plate 1; when water pump reverses; straight pin 2 under gravity; the other end drops down onto the groove of the ratchet on the ratchet cover plate 1; straight pin 2 is blocked by ratchet thus stops water pump coupler 3 to reverse, and motor is protected fully.
In sum, this water pump anti-reverse mechanism by arranging two straight pins 2 on water pump coupler 3, straight pin 2 is mounted in the ratchet cover plate 1 and is provided with on the surface of ratchet, move up and down along ratchet plane of inclination from low to high, once reverse, namely straight pin 2 is blocked by the ratchet of wheel 11 outer surfaces in the ratchet cover plate 1, thus realize automatic anti-reverse and turn, without the need to manual control, and simple and compact for structure, and working surface is little, thus minimizing amount of finish, improve manufacturing efficiency, lower to the requirement of installing, be convenient to inspection and maintenance.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
