Abstract

The utility model discloses a simple-structure manual reversing valve which comprises a front cover, a handle, a push rod and a hinge shaft. The push rod is connected on the inner side of the front cover in an inserted manner and can transversely move, the hinge shaft is longitudinally connected on the inner side of the front cover in an inserted manner and hinged to the front cover, a rack is arranged on the top face of the push rod, the hinge shaft comprises a ratchet annular distributed on the outer side face of the hinge shaft by taking the hinge shaft as an axis, the ratchet and the rack are in matched connection, and the handle is arranged on the outer side of the front cover and connected with one end of the hinge shaft. The simple-structure manual reversing valve is quite simple in structure and low in cost.

Description

A kind of hand-operated direction valve simple in structure

Technical field

The utility model belongs to a kind of valve body field, is specifically related to a kind of hand-operated direction valve simple in structure.

Background technique

Traditional hand-operated direction valve includes handle, end cap, push rod, hinge axis and pin; One end of described pin is plugged on push rod, and the other end is fixedly connected with hinge axis, and described hinge axis is connected with handle, and when operation, described handle drives the pin on hinge axis to rotate take hinge axis as axle center, thereby promotes push rod to realize operation.But this structure is very complicated.

Model utility content

(1) technical problem that will solve

The technical problems to be solved in the utility model is to make the structure of hand-operated direction valve simpler.

(2) technological scheme

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of hand-operated direction valve simple in structure, comprises protecgulum, handle, push rod and hinge axis; Described push rod is plugged on the inner side of protecgulum can transverse shifting, and described hinge axis is longitudinally plugged on the inner side of protecgulum hinged with protecgulum; The end face of described push rod includes tooth bar, described hinge axis includes take hinge axis as axle center annular spread is at the ratchet of hinge axis outer side surface, and described ratchet and tooth bar are connected, and described handle is arranged on the outside of protecgulum and one end of hinge axis is connected.

The two ends of described hinge axis are socketed with respectively 1 seal ring; Described hinge axis is tightly connected by seal ring and protecgulum.

Described hinge axis comprises 2 hinging shafts and 1 ratchet axle; Described 2 hinging shafts are separately positioned on the two ends, left and right of ratchet axle and fix clamping with ratchet axle, and described ratchet is take ratchet axle as axle center annular spread is on the outer surface of ratchet axle.

Described hinging shaft is tightly connected by seal ring and protecgulum.

Described handle comprises taper knob and handle bar; One end of described handle bar is connected with one of them hinge axis, the other end socket taper knob.

(3) beneficial effect

Hand-operated direction valve simple in structure of the present utility model, by the tooth bar clamping of ratchet and push rod of hinge axis is set, moves thereby start push rod, without the pin that transmission is set, thereby make the overall structure of hand-operated direction valve simpler, thereby reduced cost, easier for installation.

Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.

Hand-operated direction valve a kind of simple in structure as shown in Figure 1-Figure 3, comprises protecgulum 1, handle 4, push rod 2 and hinge axis 3; Described push rod 2 is plugged on the inner side of protecgulum 1 can transverse shifting, and described hinge axis 3 is longitudinally plugged on the inner side of protecgulum 1 hinged with protecgulum 1; The end face of described push rod 2 includes tooth bar 21, described hinge axis 3 includes take hinge axis 3 as axle center annular spread at the ratchet 31 of hinge axis 3 outer side surfaces, described ratchet 31 is connected with tooth bar 21, and the outside that described handle 4 is arranged on protecgulum 1 is connected with one end of hinge axis 3.When use, pull handle 4 hinge axis 3 is rotated, described ratchet 31 starts rotation, thereby realizes hand-operated direction valve operation because ratchet 31 drives push rod 2 to move with tooth bar 2.Therefore without the pin that transmission is set, make the overall structure of hand-operated direction valve simpler, thereby reduced cost, easier for installation.

The two ends of described hinge axis 3 are socketed with respectively 1 seal ring 5; Described hinge axis 3 is tightly connected by seal ring 5 and protecgulum 1, prevents leakage of oil.

Described hinge axis 3 comprises 32 and 1 ratchet axle 33 of 2 hinging shafts; Described 2 hinging shafts 32 are separately positioned on the two ends, left and right of ratchet axle 33 and fix clamping with ratchet axle 33, and described ratchet 31 is take ratchet axle 33 as axle center annular spread is on the outer surface of ratchet axle 33.Because ratchet axle 33 is with ratchet 31, so add, to make man-hour the integral material of hinge axis 3 expend very large, and this structure can be by hinge axis 3 segmentation processing, thereby have saved material.

Described hinging shaft 32 is tightly connected by seal ring 5 and protecgulum 1.

Described handle 4 comprises taper knob 41 and handle bar 42; One end of described handle bar 42 is connected with one of them hinge axis 32, the other end socket taper knob 41.

The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
