Abstract
The utility model relates to an oil level observer, which is characterized in that: the oil level observer comprises a valve body; wherein, an observing cap is assembled on one end of the valve body; a spring box is assembled on the other end of the valve body; a valve core is arranged in the valve body; one end of the valve core, on which a spring is assembled, is elastically contacted with the spring box; the other end of the valve core is contacted with the observing cap through a carrier rod; a clearance is arranged between the valve core and the valve body; and a through hole, through which oil body can flow into the observing cap of the oil level observer, is arranged on the spring box. The oil level observer has the advantages of reasonable structure design and low fabrication cost. After the transparent observing cap is taken off, the oil body in an oil tank can be effectively prevented from flowing out, the accuracy of oil level observation can be effectively ensured under the normal circumstance, and the transparent observing cap can be conveniently cleaned.
Description
Technical field
The utility model belongs to the facilities for observation technical field of oil level in the employed fuel tank of mechanical transmission, is specifically related to a kind of oil level viewer that can prevent when viewer is extractd that oil body from revealing.
Background technique
Oil level in employed gear tank of mechanical transmission such as existing machine tool, compressor or the transmission fuel tank must remain in a certain bottom line scope, oil level is crossed the low wearing and tearing that can cause transmission part in the fuel tank, must install the viewer of observing oil level on fuel tank additional for this reason.
Existing oil level viewer generally comprises the transparent observing body that a body and that is installed on the fuel tank can be observed the fuel tank internal oil level, but the transparent observing body of the oil level viewer of the type is easily because of inner prisoner of war's oil body blurred vision, can't observe normally, the transparent observing body need be carried out wiping or cleaning, with the accuracy that guarantees to observe.When taking off this oil level viewer or this transparent observing body, if the oil level in the fuel tank is positioned at more than the oil level viewer, oil body can flow out from the transparent observing body, causes the loss of oil body in the fuel tank, can't normally clear up and carry out next step accurate observation.
The model utility content
The purpose of this utility model is to provide a kind of reasonable in design, is taking off the oil level viewer that the transparent observing cap can effectively stop the outflow of oil body in the fuel tank, it can effectively guarantee the accuracy that oil level is observed under the normal condition, and is convenient to the cleaning of transparent observing cap.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of oil level viewer, it is characterized in that described oil level viewer comprises a valve body, one end of valve body is equipped with the observation cap, the other end assembling spring case, spool is set in the valve body, and with the spring case Elastic Contact, the other end contacts with the observation cap by a push rod behind the end assembling spring of spool, be provided with the gap between spool and valve body, offer the through hole that makes oil body flow into oil level viewer observation cap end on the spring case.
Concretely, described two ends of valve body is provided with internal thread, observes the threaded one end assembling of cap and valve body, and the other end screw fit of spring case and valve body is fixed.
Describedly be provided with O-ring seal, also be provided with O-ring seal with the screw thread bottom of the spring case of valve body screw fit with the valve body threaded end of observing the cap thread assembling.
Described observation cap is the transparent shell of hollow, and a convex annular table is set in the valve body, and an end of push rod contacts the back indent with the observation cap and cooperates with this convex annular table.
Contact with the extruding of spring case elasticity behind one end of the described spool assembling spring, the other end is when the observation cap takes off and the airtight cut-out oil body of the annular end face passage of described convex annular table, and the surface of contact end of described spool and convex annular table is provided with O-ring seal.
The outer wall of described valve body is provided with a circular groove, is equipped with in the groove that the oil level viewer is fixing uses seal ring, and the external wall of a side valve of described seal ring is provided with fixedly uses outside thread.
This oil level viewer is by being provided with a rubber-like spool in valve body, can guarantee to observe the unimpeded of oil body circulation passage between the cap and the oil level viewer the other end again under the normal condition.When taking off the observation cap, the spring of spool one end advances spool to observing the cap end, make between spool and valve body and form sealing mechanism, prevents that the interior oil body of fuel tank from flowing out, and realization does not have the normal cleaning of the observation cap of oil damage.
Observe between cap and spring case and valve body and all can fix by screw-thread fit, dismounting and easy to maintenance, spool observe cap by push rod under the extruding of normal assembling, form the oil body passage between its outer wall and valve interior wall, can observe the oil level situation in the fuel tank easily.
The beneficial effects of the utility model are, the reasonable in design of this oil level viewer, fabricating cost is low, can effectively stop the outflow of oil body in the fuel tank taking off the transparent observing cap, can effectively guarantee the accuracy that oil level is observed under the normal condition, and be convenient to the cleaning of transparent observing cap.
