[0001] The utility model relates to a split type electronic endoscope, especially to a split type electronic endoscope handle assembly structure. BACKGROUND
[0002] A medical endoscope is a kind of medical equipment, which can enter the stomach through the oral cavity or enter the body through other natural orifices, and is used for checking and treating the internal organs, tissues and other parts of the human body. The existing disposable endoscope usually includes a handle, an insertion tube and the like, and the handle of the disposable endoscope includes a plurality of housings which are connected to form a complete handle housing through detachable connection, and different components are installed on / inside different housings. After use, the housing for connecting the insertion tube is directly detached and discarded as a whole, and the other parts of the disposable endoscope can be reused. This not only facilitates use, reduces use cost, but also is more sanitary and reduces the risk of cross infection.
[0003] For example, a split type endoscope upper handle and lower handle locking structure is disclosed in Chinese Patent No. CN219206843U, authorized on June 20, 2023, which includes an upper handle housing, a lower handle housing and a stop safety mechanism. The bottom of the upper handle housing is provided with a plug-in stop, and the two sides of the upper handle housing are provided with exposure ports. The top of the lower handle housing is provided with an insertion part, and the two sides of the insertion part are respectively provided with mounting ports. First and second press elastic lock plates are respectively arranged in the two mounting ports. The outer side surfaces of the first and second press elastic lock plates are respectively provided with hook parts. A clamping groove is arranged on the inner wall surface of the plug-in stop. The stop safety mechanism is arranged outside the first press elastic lock plate and can be switched between the safety state and the safety release state. To separate the upper handle housing from the lower handle housing, the U-shaped toggle is turned downward to the terminal point, the abutting protrusion is separated from the stop plate, the stop safety mechanism is in the safety release state, the first and second press elastic lock plates are pressed inward, the first and second press elastic lock plates are retracted, and the hook parts are completely withdrawn from the clamping groove. Then, the lower handle housing is pulled downward, and the lower handle housing and the upper handle housing are separated. This structure is complicated to operate and inconvenient to use. UTILITY MODEL CONTENTS

[0005] In order to achieve the above object, the utility model discloses the following technical scheme: a kind of split electronic endoscope handle assembly structure of the utility model, including upper handle shell and lower handle shell, the upper handle shell bottom is equipped with upper insertion stop and upper insertion part, the lower handle shell is equipped with lower insertion stop and lower insertion part, the lower insertion part is inserted with upper insertion stop and is inserted with lower insertion stop, the upper insertion part is inserted with lower insertion stop, the upper insertion part is equipped with button and elastic locking mechanism, the button is connected with elastic locking mechanism, the lower insertion stop is equipped with button avoiding mouth, the inner wall of lower insertion stop is equipped with the clamping groove that can be clamped with elastic locking mechanism, when upper insertion part is inserted into lower insertion stop, after lower insertion part and upper insertion stop are inserted, elastic locking mechanism and clamping groove are clamped, upper handle shell and lower handle shell are connected and locked each other, when button is pressed, elastic locking mechanism and clamping groove are separated, and upper handle shell and lower handle shell can be separated.The utility model upper handle shell and lower handle shell are inserted with cooperation, by the clamping of elastic locking mechanism and clamping groove, make upper handle shell and lower handle shell lock and be fixed together, by pressing button, elastic locking mechanism and clamping groove are separated, so that upper handle shell and lower handle shell are unlocked and separated, directly pulling out upper handle shell can separate upper handle shell and lower handle shell;Relative to the locking cooperation structure of existing upper handle and lower handle, it is more simple to operate, and it is more easy and convenient to assemble and disassemble.
[0006] As preferred, the elastic locking mechanism includes a pair of locking sliders, which are slidingly arranged in the upper insertion part. The locking slider includes a sliding block and a locking arm arranged on the sliding block. The locking arm can be inserted into or withdrawn from the clamping groove. A spring is arranged between the sliding blocks. A driving slope is arranged on the outer side of the sliding block. The button is movably connected to the upper insertion part. A pressing arm is arranged on the button. The pressing arm passes through the upper insertion part. An extrusion slope is arranged on the end of the pressing arm, which is in contact with the driving slope. When the spring is in a natural state, the outer end of the locking arm is exposed outside the upper insertion part under the action of the spring (against the sliding block). By pressing the button, the extrusion slope extrudes the driving slope inward, so that the two sliding blocks are close to each other. The outer end of the locking arm is retracted into the upper insertion part, so that the upper insertion part can be inserted into the lower insertion stop.

When the upper handle shell and the lower handle shell are to be separated, the button is pressed, so that the extrusion slope extrudes the driving slope inward, so that the two sliding blocks are close to each other. The outer end of the locking arm is retracted into the upper insertion part until it is withdrawn from the clamping groove. At this time, the upper handle shell and the lower handle shell are unlocked and separated, so that the upper handle shell can be pulled out. A guide slope can also be arranged on the outer end of the locking arm. When the outer end of the locking arm is extruded, the spring is compressed, so that the outer end of the locking arm is automatically retracted into the upper insertion part, without the need to press the button. The direct insertion cooperation of the upper handle shell and the lower handle shell can be realized.
[0007] As preferred, the upper insertion part is provided with a stepped long circular hole, and a sliding block connecting screw is arranged in the stepped long circular hole, and the sliding block connecting screw is threadedly connected with a sliding block and can slide along the stepped long circular hole.
[0008] As preferred, the upper insertion part is provided with a button connecting screw, and the button screw passes through the upper insertion part and is threadedly connected with a button.
[0009] As preferred, the inner side surface of the sliding block is provided with a spring limiting groove, and both ends of the spring are arranged in the spring limiting groove.
[0010] As preferred, the upper insertion part is provided with a sliding block limiting plate, and the sliding block limiting plate is arranged outside the sliding block.
[0011] Therefore, the utility model has the following beneficial effects: through the clamping of the elastic locking mechanism and the clamping groove, the upper handle shell and the lower handle shell are locked and fixed together, by pressing the button, the elastic locking mechanism and the clamping groove can be separated, so that the upper handle shell and the lower handle shell are unlocked and separated, thereby the upper handle shell and the lower handle shell can be separated, compared with the locking and cooperation structure of the existing upper handle and lower handle, the operation is more simple, and the assembly and disassembly are more convenient.
