Abstract
The utility model relates to an anti-reverse device provided with a novel anti-reverse end cover, which comprises a bearing base, an anti-reverse end cover, a pin hole, a bearing, an anti-reverse disk, round nuts, a frame oil seal, a rotating shaft, keys, a column pin, a bearing sleeve, a felt oil seal, adjusting nuts and screws. The utility model is characterized in that a through hole is arranged on the top of the pin hole of the anti-reverse end cover; and the diameter of the through hole is smaller than that of the column pin. The utility model has the advantages that before starting a water pump, users can observe the position of the column pin by a observation hole; if the column pin is stopped above the pin hole because of the effect of the friction force, users can use iron wires or other thin articles to press the column pin down, thereby guaranteeing the normal operation of the anti-reverse device.
Description
Technical field
The utility model relates to a kind of anti-reverse end cap of anti-reverse mechanism, particularly a kind of anti-reverse mechanism with novel anti-reverse end cap.
Background technique
Vertical sewage pump is easy to form counter-rotating when starting, so the counter-rotating will prevent starting mode of pump with anti-reverse mechanism the time.Anti-reverse end cap is a component part of anti-reverse mechanism, when water pump will reverse, straight pin can fall in the groove on the counnter attack rotating disk, block the rotation of anti-reverse end cap by straight pin, and anti-reverse end cap and axle are by the key transmission, axle also stops operating like this, thereby has stoped the counter-rotating of water pump, and this is that anti-reverse mechanism prevents the principle of reversing.But because the gap of the pin-and-hole of straight pin and anti-reverse end cap must be less, and they all have certain roughness, in actual motion straight pin be easy to be subjected to the effect of frictional force and rest on pin-and-hole above, straight pin falls less than in the groove on the counnter attack rotating disk when water pump reverses, thereby does not have the effect that prevents the water pump counter-rotating.
Summary of the invention
The purpose of this utility model is to solve the problem that exists frictional force to make that straight pin can't fall sometimes between straight pin on the anti-reverse end cap of anti-reverse mechanism in the prior art and the pin-and-hole, and a kind of anti-reverse mechanism with novel anti-reverse end cap is provided.A kind of anti-reverse mechanism of the utility model design with novel anti-reverse end cap, comprise bearing support, anti-reverse end cap, pin-and-hole, bearing, counnter attack rotating disk, round nut, outside framework oil seal, rotating shaft, key, straight pin, bearing housing, felt collar oil sealing, adjust nut, screw, it is characterized in that: on the pin-and-hole top of anti-reverse end cap, a through hole is arranged.The diameter of through hole is less than the diameter of straight pin.The utility model has the advantages that before starting mode of pump, the user can observe the residing position of straight pin by peep hole, if straight pin is subjected to the top that the effect of frictional force rests on pin-and-hole, the user can subdue straight pin by thin objects such as iron wires, thereby guarantees the normal use of anti-reverse mechanism.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The top processes the through hole 6 of a diameter less than straight pin 11 above the pin-and-hole 3 on the anti-reverse end cap 2, before starting mode of pump, the user can observe straight pin 11 residing positions by through hole 6, if straight pin 11 is subjected to the top that the effect of frictional force rests on pin-and-hole 3, the user can subdue straight pin 3 by objects such as iron wires, thereby guarantees the normal use of anti-reverse mechanism.Through hole 6 diameters must fly out from through hole 6 when water pump rotates to prevent straight pin 11 less than the diameter of pin-and-hole 3.
Claims (2)
1. anti-reverse mechanism with novel anti-reverse end cap, comprise bearing support, anti-reverse end cap, pin-and-hole, bearing, counnter attack rotating disk, round nut, outside framework oil seal, rotating shaft, key, straight pin, bearing housing, felt collar oil sealing, adjust nut, screw, it is characterized in that: on the pin-and-hole top of anti-reverse end cap, a through hole is arranged.
2. by the described a kind of anti-reverse mechanism with novel anti-reverse end cap of claim 1, it is characterized in that: the diameter of through hole is less than the diameter of straight pin.
