Abstract
The utility model relates to a screwed coupler with observing holes. The screwed coupler comprises the screwed coupler, and is characterized in that two observing holes are formed in the two side faces on the middle position of the screwed coupler, are through holes, are communicated with an internal hole of the screwed coupler and are uniformly distributed along the periphery of the outer side of the screwed coupler; and the diameter of the observing holes is 5mm. The screwed coupler has the advantages that whether matched surfaces of two shafts are jacked together or not is observed through the observing holes, so that whether the screwing depth of the two shafts is equal or not is conveniently observed when the screwed coupler is connected with the two shafts; and whether the end surfaces of the two shafts are jacked together or not is determined, so that the phenomenon of vibration of a water pump caused by poor assembly is prevented.
Description
Technical field
The utility model relates to a kind of screwed coupling structure for the vertical draining pump of major axis, the particularly improvement of double thread coupler structure.
Background technique
The vertical draining pump of major axis is to belong to the major axis pump, and the quantity of every pump axis is a lot, and axle head all car has screw thread.Is connected by screwed coupling between axle and the axle, the requirement counterface must withstand on together during the connections of two axles, and the degree of depth that two axles are screwed into screwed coupling will equate, otherwise can influence intensity.But in existing structure, screwed coupling is enclosed construction, can't observe inner case, is screwed into deep equality so just can't guarantee two axles, can't judge that also the end face of two axles withstands on together, if do not withstand on the vibrations that can cause water pump together.
Summary of the invention
The purpose of this utility model is to solve screwed coupling in the prior art can't determine being screwed into the degree of depth and whether equating of two axles when connecting two axles, the end face that also can't judge two axles withstands on existing problem together, and a kind of novel screwed coupling structure is provided.The utility model design has the screwed coupling of peep hole, comprise screwed coupling, it is characterized in that: the bi-side in the screwed coupling neutral position offer peep hole, peep hole is through hole, be communicated with the endoporus of screwed coupling, peep hole is 2, and is uniform along screwed coupling outer circumference direction, and the diameter of peep hole is 5mm.Whether the utility model advantage is and withstands on together by the fitting surface that peep hole is observed two axles, thereby made things convenient for screwed coupling being screwed into the degree of depth and whether equating of two axles when connecting two axles, and judge whether the end face of two axles withstands on together, and avoided the water pump seismism that cause because assemble not in place.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing 1 is the prior art constructions schematic representation.
Accompanying drawing 2 is structural representation in use of the present utility model.
Embodiment
Comprise screwed coupling 1 among the figure, it is characterized in that: offer peep hole 2 in the bi-side in screwed coupling neutral position, peep hole is through hole, be communicated with the endoporus 3 of screwed coupling, peep hole is 2, and is uniform along screwed coupling outer circumference direction, and the diameter of peep hole is 5mm.
Portion in the screwed coupling neutral position processes peep hole, and peep hole is through hole, and quantity is 2, and is along the circumferential direction uniform, and the diameter of peep hole is 5mm.At first screwed coupling is screwed into lower shaft 4 in use, can whether arrives the central position of peep hole by the fitting surface that peep hole is observed lower shaft, if arrive the central position of peep hole, then be seated.And then will go up axle and 5 be screwed into screwed coupling, and whether withstand on together by the fitting surface that peep hole is observed two axles, thereby made things convenient for use, and avoided the water pump seismism that causes because assembling is not in place.
Claims (1)
1. the screwed coupling that has peep hole, comprise screwed coupling, it is characterized in that: the bi-side in the screwed coupling neutral position offer peep hole, peep hole is through hole, be communicated with the endoporus of screwed coupling, peep hole is 2, and is uniform along screwed coupling outer circumference direction, and the diameter of peep hole is 5mm.
