Description
Technical field
The invention belongs to internal-combustion engine injection system field, relate in particular to a kind of assembly preventing delivery valve holder from loosening.
Background technique
Delivery valve holder is the main constituent elements of diesel engine high-pressure injection pump.High-pressure injection pump mainly compresses the surface of contact of plunger coupled parts and delivery valve matching parts by delivery valve holder, form seal space.More common method carries out annular knurl in the middle part of twin cylinder pump delivery valve holder cylindrical at present, is then fixed by two semi-circular pressing plates.This device not only increases the manufacturing procedure of delivery valve holder, and structure is loaded down with trivial details, and after long-term use, by the pressing plate of bolt presses, easily occurs loosening situation thus lose anti-loosing effect.
Model utility content
The utility model, for the deficiencies in the prior art, provides a kind of structure preventing delivery valve holder from loosening, and prevents from being connected between delivery valve holder with the pump housing loosening, and ensures sealing and pump oil pressure, works more reliably, more stable, longer service life.And overall structure is compacter.
For achieving the above object, the utility model provides a kind of assembly preventing delivery valve holder from loosening, and comprises tight seat and puts control strip, delivery valve holder and fixed connecting piece, wherein, one end that control strip is put at said tight seat offers interior dodecagonal binding groove, and the other end offers mounting groove; Described delivery valve holder comprises the locking portion of tight seat, and the described locking portion of tight seat is hexagon, and closely cooperates with described binding groove; Described fixed connecting piece is arranged in mounting groove, is fixed on oil jet pump body by described restraint location control strip.
Further, described mounting groove is kidney slot.
Further, described mounting groove is circular trough.
Further, described tight seat is put control strip and is adopted metal material.
Further, described fixed connecting piece is bolt.
Further, it is flake structure that control strip is put at described tight seat, and described binding groove is sleeved on around the locking portion of tight seat, and close contact peripheral with the locking portion of tight seat.
The beneficial effects of the utility model:
Structure is simple, and facilitate attractive in appearance, anti-loosing effect is better.
The locking modular construction of delivery valve holder is simple, shim designs, and locking for tight seat parts are fixed on the pump housing with bolt by the tight seat of hexagonal of interior 12 jiaos of clamping stagnation delivery valve holders, and simple design can effectively prevent tight seat from loosening.

The implication of the "and/or" described in the utility model refers to respective individualism or both simultaneous situations include interior.
The implication of " inside and outside " described in the utility model refers to relative to equipment itself, in the direction of sensing equipment inside is, otherwise is outward, but not the specific restriction to equipment mechanism of the present utility model.
When the implication of " left and right " described in the utility model refers to reader just to accompanying drawing, the left side of reader is a left side, and the right of reader is the right side, but not the specific restriction to equipment mechanism of the present utility model.
The indirect connection that can be the direct connection between parts also can be by other parts between parts of the implication of " connection " described in the utility model.
As illustrated in fig. 1 and 2, the assembly preventing delivery valve holder 2 from loosening, comprises tight seat and puts control strip 1, delivery valve holder 2 and fixed connecting piece, wherein, one end that control strip 1 is put at said tight seat offers interior dodecagonal binding groove, and the other end offers mounting groove.
As shown in Figure 4, delivery valve holder 2 comprises the locking portion of tight seat, and the locking portion of tight seat is hexagon, and closely cooperates with binding groove; Fixed connecting piece is arranged in mounting groove, is fixed on oil jet pump body by restraint location control strip.
As preferred a kind of mode of execution, mounting groove is kidney slot or circular trough.
As preferred a kind of mode of execution, tight seat is put control strip 1 and is adopted metal material.
As preferred a kind of mode of execution, fixed connecting piece is bolt.
As shown in Figure 3, control strip 1 is put for flake structure in tight seat, and binding groove is sleeved on around the locking portion of tight seat, and close contact peripheral with the locking portion of tight seat.
The locking modular construction of delivery valve holder is simple, shim designs, the tight seat of hexagonal of interior 12 jiaos of clamping stagnation delivery valve holders, the inwall of interior 12 jiaos is just by tight for hexagonal seat card master, in 12 jiaos combine the tight seat of the hexagonal that can meet delivery valve holder with kidney slot and be in any position and can be fixed, be fixed on the pump housing with bolt by locking for tight seat parts, simple design can effectively prevent tight seat from loosening.
These are only mode of execution of the present utility model, it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
