Description

Multi-functional turnbuckle

Technical field

The utility model relates to self-balancing multi-stage pump field, relates in particular to a kind of turnbuckle structure for self-balancing multi-stage pump in parallel.

Background technology

Self-balance horizontal multistage centrifugal pump turnbuckle structure of the prior art has the following disadvantages:

(1) when turnbuckle is screwed into water exit end, the air in water exit end screw cannot be discharged fast, brings very large difficulty to assembling;

(2), when turnbuckle is screwed into water inlet-outlet segment, coat antirust oil on the screw thread of turnbuckle time, the air in water exit end screw cannot be discharged at all, otherwise, bolt can get rusty, extremely difficult when later pump does maintaining;

(3) when turnbuckle is screwed into water exit end, the screw thread of turnbuckle or water exit end screw have trickle iron filings to drop unavoidably, and the assembling of turnbuckle is extremely difficult;

(4) when turnbuckle is screwed into water exit end, on turnbuckle, without stopping step, often damage the screw of water exit end and the screw thread of turnbuckle, cause water exit end or turnbuckle to be scrapped, bring massive losses;

(5) clamp turnbuckle A-A place while tightening turnbuckle with pipe wrench, pipe wrench often damages the screw thread of turnbuckle rear end, and pump causes hex nut cannot exit turnbuckle in the time doing maintaining.

Summary of the invention

For solving assembling and dismounting difficulty that existing turnbuckle exists, easily get rusty, the problem such as fragile, it is a kind of simple in structure that the purpose of this utility model is to provide, assembling, convenient disassembly, long-lived multi-functional turnbuckle.

For achieving the above object, the utility model provides following technical scheme:

Multi-functional turnbuckle, comprises turnbuckle, and the preceding thread end of turnbuckle is embedded with multi-functional chip removal groove, and the preceding thread end of turnbuckle is provided with stopping step, and the rear thread end of turnbuckle is provided with protection step.

Preferably, the section of described protection step is square.

Multi-functional turnbuckle of the present utility model has following beneficial effect: (1) is provided with multi-functional chip removal groove, and application antirust oil is convenient in exhaust smoothly, has both chip removal etc. multi-functional; (2) stopping step of turnbuckle preceding thread end can well be protected the screw thread in water exit end screw, the also screw thread of fine protection turnbuckle of while; (3) the protection step section of turnbuckle rear thread end is square, is convenient to aerodynamic wind big gun sleeve and assembles fast, can fine protection turnbuckle rear end screw thread; (4) this multi-functional turnbuckle can be protected and replace the spare parts mutually harmless badly in when assembling, and quick-detachment when assembling, maintaining, has improved operating efficiency greatly fast, has reduced the technical ability requirement to skilled worker, brings considerable economic benefit simultaneously.

Brief description of the drawings

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be done to simple introduction below, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.

Accompanying drawing 1 is the structural representation of the utility model embodiment.

Accompanying drawing 2 is B part partial enlarged drawing in accompanying drawing 1;

Accompanying drawing 3 is C part partial enlarged drawing in accompanying drawing 1;

Accompanying drawing 4 is the structural representation of turnbuckle in prior art;

Accompanying drawing 5 is B part partial enlarged drawing in accompanying drawing 4.

In accompanying drawing, 1 is water exit end, and 2 is stage casing, and 3 is turnbuckle, and 4 is inlet segment, and 5 is circular gasket, 6 hex nuts, and 7 is chip area, and 8 is preceding thread stopping step, and 9 is rear thread protection step.

Detailed description of the invention

Below by specific embodiment, the utility model is further described.

A kind of multi-functional turnbuckle, as shown in accompanying drawing 1, accompanying drawing 2 and accompanying drawing 3, comprises turnbuckle 3, and the preceding thread end of turnbuckle is embedded with multi-functional chip removal groove 7, and the preceding thread end of turnbuckle is provided with stopping step 8, and the rear thread end of turnbuckle is provided with protection step 9.

Wherein, the A-A section of described protection step is square.

Specific implementation method of the present utility model is: centrifugal multistage pump multiple centrifugal pump comprises water exit end 1, stage casing 2 and inlet segment 4. First by turnbuckle 3 front end application antirust oil, entangle turnbuckle four directions tail end with aerodynamic wind big gun sleeve, be screwed in water exit end screw through inlet segment 4, in the time that the stopping step 8 of turnbuckle is close to water exit end, now turnbuckle is tightened; Circular gasket 5 is through turnbuckle, and hex nut 6 is screwed into turnbuckle until tighten hex nut 6.

Turnbuckle of the prior art is as shown in accompanying drawing 4 and accompanying drawing 5; chip area is not set; the diameter of thread is equally large with outside diameter; and do not establish protection step; aerodynamic wind big gun sleeve can damage the screw thread of rear end in the time tightening pull bar, therefore, often damages the screw of water exit end and the screw thread of turnbuckle; cause water exit end or turnbuckle to be scrapped, bring massive losses.

The utility model is simple in structure, in the turnbuckle structure of existing self-balance horizontal multistage centrifugal pump, provides a kind of efficient, economic, easy multi-functional turnbuckle.

Applied specific embodiment herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof. The above is only preferred embodiment of the present utility model, should be understood that, due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for those skilled in the art, not departing under the prerequisite of the utility model principle, can also make some improvement, retouching or variation, also above-mentioned technical characterictic can be combined by rights; These improve retouching, change or combination, or without improving, the design of utility model and technical scheme are directly applied to other occasion, all should be considered as protection domain of the present utility model.
