Description
Technical Field
The utility model belongs to the technical field of the anastomat part installation technique and specifically relates to a novel mounting structure of turn button and steering spindle dish for anastomat.
Background
The steering shaft disc and the steering button are parts of a straight line cutting anastomat body for the endoscope, and the steering shaft disc and the steering button are used for steering an assembly connected with the anastomat body at the upper and lower rotating shaft sleeve parts. The steering button and the steering shaft disc assembly are fixed through a steering button fixing pin. The holes need to be aligned for installing the fixing pin of the steering button, and then the fixing pin of the steering button is installed, which is troublesome. The steering button fixed pin is interference fit with the steering shaft disc assembly, the outer diameter of the pin is small, the pin needs to be sunk into the steering button, and the positioning requirement on the tool is high.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the utility model provides a novel mounting structure of steering button and steering shaft dish for improved anastomat.
The utility model provides a technical scheme that its technical problem adopted is: a novel mounting structure of a steering button and a steering shaft disc for an anastomat comprises a connecting block arranged on the anastomat, wherein a rotary shaft sleeve is arranged on the connecting block, the steering shaft disc is pre-installed in the rotary shaft sleeve, the steering shaft disc comprises a base and a connecting column vertically arranged on the base, a knurled structure is arranged at the end part of the connecting column, the steering button is pressed on the steering shaft disc, a connecting pipe is arranged in the center of the steering button, and the connecting pipe and the connecting column are in interference fit to enable the structure to be stable during press mounting;
furthermore, two vertical positioning grooves which are symmetrical left and right are arranged on the connecting column, so that the steering button with positioning requirements is convenient to position when being pressed and mounted;
furthermore, the knurling structure of the utility model is a ratchet-shaped or wavy structure, the machining ensures the precision, the interference fit with the steering button is realized during the assembly, the through hole matched with the fixing pin of the steering button is cancelled, and the friction force between the steering shaft disc and the steering button is increased;
further, the annular knurl structure with spliced pole formula forming structure as an organic whole.
Furthermore, the connecting block include last connecting block or lower connecting block of anastomat.
The utility model has the advantages that: the defects in the background technology are overcome, and the method has the following advantages: 1. the steering shaft disc and the steering button are provided with pin holes and fixing pins of the steering button, so that one-step assembly process is reduced; 2. the knurling has been increased to steering spindle dish upper end, and the pressure equipment is convenient, and steering spindle dish and steering button cooperation are firm, are difficult for droing, satisfy normal operation requirement.

Detailed Description
The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The embodiment of the utility model relates to a novel mounting structure of a steering button and a steering shaft disc for an anastomat, as shown in fig. 1, fig. 2 and fig. 3, comprises a connecting block 1 arranged on the anastomat, wherein a rotary shaft sleeve 2 is arranged on the connecting block 1, the steering shaft disc is preassembled in the rotary shaft sleeve 2, the steering shaft disc comprises a base 3 and a connecting column 4 vertically arranged on the base 3, the end part of the connecting column 4 is provided with a knurled structure 5, the steering shaft disc is crimped with a steering button 6, the center in the steering button 6 is provided with a connecting pipe 7, the connecting pipe 7 and the connecting column 4 are in interference fit during press mounting to enable the structure to be stable, the connecting column 4 is provided with two vertical positioning grooves 8 which are bilaterally symmetrical, and the steering button 6 with positioning requirements is convenient to position during press mounting; the knurling structure 5 is a ratchet-shaped structure, the machining ensures the precision, the interference fit with the steering button 6 is realized during the assembly, a through hole matched with a fixing pin of the steering button 6 is eliminated, and the friction force between the steering shaft disc and the steering button 6 is increased; the knurling structure 5 and the connecting column 4 are of an integrated forming structure.
The working principle is as follows: load steering button 6 on the steering spindle dish earlier, then with steering button 6 safe impressing on the steering spindle dish, connecting pipe in the steering button 6 and spliced pole 4 on the steering spindle dish realize interference fit through annular knurl structure 5 this moment, annular knurl structure 5 makes and has sufficient frictional force in order to ensure the stability of whole structure between steering spindle dish and the steering button 6, be difficult for droing.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
