Abstract
The utility model discloses a thrust disc for pump with location structure, including keyway and thrust disc body, the keyway is located mesopore upper portion, the mesopore outside is provided with the inner ring, the inner ring outside is provided with the outer loop, be provided with screw and locating hole between the interior ring sum outer loop, be provided with the internal thread in the screw thread, the internal thread outside is provided with the external screw thread, be provided with in the locating hole and fasten the post. This thrust disc for pump with location structure has improvement life, the easy dismantlement, and the convenience is maintained, improves the advantage of installation accuracy.
Description
Technical field
This utility model belongs to pump thrust disc technical field, is specifically related to a kind of pump thrust disc with location structure.
Background technology
The assembling mode of conventional pump, it is generally with multiple screws, thrust disc to be locked on the pump case of pump, its set-up mode the most first offers multiple perforation at pump thrust disc, separately it is correspondingly arranged multiple screw in pump case, one end of each screw run through the perforation of pump again and is locked in screw, according to this pump being locked in casing.In addition to must using hand-held tool, its group sets time length and is difficult to again operation, and it is not easy to maintenance and the replacing of pump, for this, a kind of mode utilizing fastening structure to replace existing screw locking pump is arisen at the historic moment, and the group that thrust disc is locked in pump case by fastening structure sets mode, is to be located at folded for thrust disc on pump case, then by during wherein a mother buckle is arranged on the perforate of thrust disc and pump case, the purpose both combining is reached.But, owing to the contact area between male and female fastener is little, therefore fastening power is not enough and separations that get loose, it addition, tolerance during manufacture the most easily affects the size of fastening power；Furthermore, fastening structure, after repeatedly vibration, also can occur the phenomenon separated, cause the inconvenience in use and puzzlement between male and female fastener.
Utility model content
The purpose of this utility model is to provide a kind of pump thrust disc with location structure, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, this utility model following technical scheme of offer: a kind of pump thrust disc with location structure, including keyway and thrust disc body, described keyway is positioned at mesopore top, is provided with internal ring, is provided with outer shroud outside described internal ring outside described mesopore, screw thread and hole, location it is provided with between described internal ring and outer shroud, being provided with female thread in described screw thread, be provided with external screw thread outside described female thread, described location is provided with hitching post in hole.
Preferably, hole, described location is uniformly arranged 2～4.
Preferably, described screw thread is uniformly arranged 4～6.
Preferably, hole, described location and screw thread distribute alternately.
Technique effect of the present utility model and advantage: should be with the pump thrust disc of location structure, by arranging hole, location, it is achieved that the location of pump thrust disc；By being uniformly arranged hole, multiple location, reach being accurately positioned of pump thrust disc；By being uniformly arranged multiple screw thread, reach the purpose of pump thrust disc and the connection of pump case；Raising service life should be had with the pump thrust disc of location structure, easily disassembled, convenient maintenance, the advantage improving installation accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1 keyway, 2 mesopores, 3 internal ring, 4 outer shrouds, 5 female threads, 6 external screw threads, 7 location hole, 8 centrages, 9 screw threads, 10 thrust disc bodies.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
This utility model provides a kind of pump thrust disc with location structure as shown in Figure 1, including keyway 1 and thrust disc body 10, described keyway 1 is positioned at mesopore 2 top, it is provided with internal ring 3 outside described mesopore 2, it is provided with outer shroud 4 outside described internal ring 3, screw thread 9 and hole 8, location it is provided with between described internal ring 3 and outer shroud 4, described screw thread 9 is provided with female thread 5, described screw thread 9 is uniformly arranged 4～6, it is provided with external screw thread 6 outside described female thread 5, hole, described location 8 is provided with hitching post 7, hole, described location 8 is uniformly arranged 2～4, hole, described location 8 and screw thread 9 distribute alternately.
Operation principle: first, is accurately positioned the hole, location with pump by hole 8, pump thrust disc 10 body location, navigates to correct position, finally, then be tightened on pump case by pump thrust disc 10 body by screw thread 9 with bolt by pump thrust disc 10 body with hitching post 7.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; it is not limited to this utility model; although this utility model being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
