However, the existing medical wiring harness has defects, for example, the existing medical wiring harness generally adopts the anti-tripping plastic tenon design to achieve the anti-pulling effect, and after the packaging anti-tripping harness is used for a period of time, the fixing strength of the anti-tripping harness is reduced due to the aging of the plastic.

Disclosure of Invention

The invention mainly provides a novel pulling-resistant wire harness for a medical apparatus product, which is used for solving the technical problems in the background technology.

The technical scheme adopted by the invention for solving the technical problems is as follows:

the utility model provides a novel medical instrument product is with anti-drawing pencil, including the wire, the output of wire is fixed with the plug, the plug is pegged graft with the socket mutually, the inside of plug is fixed with the wire cover, the bilateral symmetry of wire cover is equipped with L shape slider, every the one end of L shape slider all runs through L shape guiding hole and is connected with spacing dish, every L shape guiding hole all set up with on the casing of plug, and every L shape slider is kept away from same one side the equal butt in one side of spacing dish has the jack catch, every the bottom of jack catch all runs through the casing of plug and through the spring with the inner wall of plug is connected, the socket is close to the one end of plug is fixed with the cutting ferrule, cutting ferrule and two jack catch looks joint.

Further, the wire is including tensile sinle silk, the peripheral of tensile sinle silk is encircleed and is equipped with a plurality of transmission pencil, and is a plurality of transmission pencil with bond each other through insulating rubber between the tensile sinle silk, it is a plurality of the peripheral cladding of transmission pencil has the flame retardant coating, the outside cladding of flame retardant coating has insulating skin.

Furthermore, the diameter length of each limiting disc is larger than the width length of the L-shaped guide hole on the same side, and each limiting disc is in meshed connection with one end, far away from the clamping jaw, of the L-shaped sliding sheet on the same side through threads.

Furthermore, one end of the lead close to the socket is a flexible head.

Furthermore, the outer peripheral surface of the lead is sleeved with a plastic spring sleeve.

Further, the bottom of one end of each L-shaped sliding piece close to the same side of the clamping jaw is in meshed connection with the outer peripheral surface of the wire guide sleeve through threads.

Furthermore, the surface of one side of each limiting disc, which is far away from the L-shaped sliding sheet on the same side, is provided with anti-skid grains.

Furthermore, each cutting ferrule all through the screw thread with the socket meshing is connected, every cutting ferrule's cross section is the font.

Compared with the prior art, the invention has the beneficial effects that:

firstly, the fixing strength reduction caused by plastic aging can be overcome, the separation of the wire harness from the medical apparatus and instruments is effectively prevented when the device is stressed, the limit disc is pushed through the matching of the plug and the socket, the limit disc drives the L-shaped sliding sheet on the limit disc to move along the L-shaped guide hole on the plug, the inclined surface of the L-shaped sliding sheet is abutted against the inclined surface of the claw, so that the claw is driven to lift when the L-shaped sliding sheet slides until the hook-shaped part of the claw extends out of the plug, and the hook-shaped part of the claw can hook the clamping sleeve on the socket at the moment to limit the movement of the plug.

Secondly, the invention can limit the motion of the L-shaped sliding piece, prevent the L-shaped sliding piece from shaking due to the interference of external force factors, and when the L-shaped sliding piece rotates by the guidance of the L-shaped guide hole, the L-shaped sliding piece is engaged with the outer peripheral surface of the wire guide sleeve by screw threads, so that the screw threads assist the L-shaped guide hole to limit the sliding of the L-shaped sliding piece.

Thirdly, the plastic spring sleeve sleeved on the lead prevents a user from touching the leaky lead by mistake and simultaneously prevents the lead from scraping other equipment to cause the loss of the lead.

The present invention will be explained in detail below with reference to the drawings and specific embodiments.
