Description

Spring pressing type instrument connecting structure

Technical Field

The utility model relates to the field of medical equipment, especially, relate to a spring is according to formula apparatus connecting structure.

Background

In order to realize convenient disassembly and cleaning and reuse of the existing medical apparatus, the medical apparatus generally adopts a structural mode that two detachable apparatuses are connected for use, the existing apparatus and the existing apparatus are generally connected by threads, and the connecting method can be screwed up only by rotating the apparatus for a plurality of circles. If the screw is not tightened, the screw can be loosened; if the screw is too tight, the screw is difficult to disassemble, and the use and the disassembly are very inconvenient.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model discloses a spring press type instrument connection structure.

The utility model adopts the following technical scheme:

a spring-push type instrument connecting structure comprises an instrument A and an instrument B, the instrument A and the instrument B are detachably connected, a connecting end of the instrument A comprises a conical matching surface and a groove arranged on a conical matching surface end connecting surface, a connecting end of the instrument B comprises a conical matched surface and a connecting ring fixedly connected with the conical matched surface end, the connecting ring comprises a fixing ring and a floating ring, a pin shaft is fixedly arranged outside the upper side of the fixing ring, the floating ring is inserted into the pin shaft, the floating ring floats relative to the fixing ring through the pin shaft, a spring button is fixedly arranged outside the lower side of the fixing ring, the spring button comprises a spring, a button inner core and a button outer sleeve, the button outer sleeve is fixedly connected with the floating ring, the button outer sleeve can slide outside the button inner core, the spring is arranged between the button outer sleeve and the button inner core inside the button, a pin is, the pin is in fit clamping with the groove, and the conical matching surface is matched with the conical matched surface.

Preferably, the button inner core and the fixing ring are welded and fixed.

Preferably, the button outer sleeve is fixed with the floating ring in a welding mode.

The utility model has the advantages that: when the spring press type instrument connecting structure is connected, only the instrument A needs to be inserted into the instrument B and inserted to the bottom, the conical matching surface and the conical matched surface are matched, and the pin is matched and clamped with the groove, so that connection can be completed. When the device is disassembled, the device A can be pulled out from the device B only by pressing the button outer sleeve, and the connection and the disassembly are very convenient and stable.

Detailed Description

The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:

example (b): as shown in the attached figures 1-5, a spring-push type instrument connecting structure comprises an instrument A1 and an instrument B2, the instrument A and the instrument B are detachably connected, a connecting end of the instrument A comprises a conical matching surface 6 and a groove 7 arranged on a connecting surface at the tail end of the conical matching surface, the connecting end of the instrument B comprises a connecting ring fixedly connected with a conical matched surface 11 and the tail end of the conical matched surface, the connecting ring comprises a fixing ring 13 and a floating ring 14, a pin shaft 15 is fixedly arranged outside the upper side of the fixing ring, the floating ring is inserted into the pin shaft, the floating ring floats relative to the fixing ring through the pin shaft, a spring button is fixedly arranged outside the lower side of the fixing ring, the spring button comprises a spring 8, a button inner core 10 and a button outer sleeve 9, the button inner core is welded and fixed with the fixing ring, the button outer sleeve is welded and fixed with the floating ring, a pin 12 is arranged on the left side and the right side of the floating ring, the pin is matched and clamped with the groove, and the conical matching surface is matched with the conical matched surface.

When the spring press type instrument connecting structure is used, only the instrument A needs to be inserted into the instrument B and inserted to the bottom, the conical matching surface and the conical matched surface are matched, the pin can slide to the position B4 from the position A3, then the floating ring drives the pin to slide to the position C5 under the action of the spring, and if the button is not pressed, the pin cannot slide out of the groove, namely the instrument A cannot be separated from the instrument B. When the pin is in the position C, the taper matching surface and the taper matched surface are just fit with each other. If the pin needs to be pulled out, the floating ring moves to drive the pin to slide from the position C to the position B only by pressing the button outer sleeve, and the pin can be pulled out of the instrument A when in the position B to finish the disassembly.
