Description

Technical Field

[0001] The invention relates to a quick-change device with automatic handle identification for rehabilitation equipment, belonging to the technical field of medical rehabilitation equipment. Background Art

[0002] There are more and more types of medical rehabilitation equipment. Most upper limb medical rehabilitation end handles are non-quick-change structures. Every time a handle with a different function is replaced, the user must set up the corresponding program on the device's operation page before the rehabilitation personnel can perform the corresponding rehabilitation training. The functions of quick handle replacement and automatic handle identification cannot be realized. This increases the inconvenience of equipment operation and greatly reduces the user's rehabilitation experience. Summary of the invention

[0003] The purpose of the present invention is to design a quick-change device for rehabilitation equipment with automatic handle identification, which solves the problem that most upper limb medical rehabilitation terminal handles cannot be quickly replaced and cannot identify different handles.

[0004] In order to achieve the above purpose, the technical solution of the present invention is:

[0005] A quick-change device for rehabilitation equipment with automatic handle identification, characterized by comprising:

[0006] A knob pull cover, an oblique pull pin, a base, and a straight handle or a tow handle for mounting on the base;

[0007] A matching hole is provided in the middle of the base, and the matching hole includes a plane side and an inner circle side;

[0008] The knob cover is connected to one end of the bevel pull pin, and the other end of the bevel pull pin is provided with a cone. A circular hole for the bevel pull pin to pass through is opened on the inner plane side of the matching hole of the base, and the cone passes through the base and is arranged in the matching hole. The bevel pull pin is supported on the base through an elastic support;

[0009] The straight handle or the drag handle has a boss at one end for installation in the matching hole, a conical hole is provided on the flat side of the boss to match the cone, a proximity switch is provided on the inner circle side of the matching hole, and a corresponding induction pin is provided on the boss of the straight handle or the drag handle for distinguishing between the straight handle and the drag handle.

[0010] Preferably, the knob pull cover is provided with a pin hole on one side; one end of the oblique pull pin is connected to the knob pull cover and cooperates with the pin hole of the knob pull cover.

[0011] Preferably, the elastic support is a compression spring, which is sleeved on the bevel pull pin. One end of the compression spring abuts against the cone of the bevel pull pin, and the other end abuts against a spring pressure plate. The spring pressure plate is installed on the base, and a central channel is opened in the middle for the bevel pull pin to pass through.

[0012] Preferably, a plurality of circular holes are opened on the inner circular side of the matching hole, and the proximity switches are arranged in the circular holes.

[0013] Furthermore, the arc surface of the boss of the straight handle is provided with a plurality of circular holes for installing the induction pins, and the arc surface of the boss of the drag handle is provided with a plurality of circular holes for installing the induction pins, and the number of induction pins installed on the straight handle is different from the number of induction pins installed on the drag handle.

[0014] The device of the present invention can quickly lock or unlock the straight handle and the drag handle through the oblique pull pin and the knob pull cover. The rehabilitation equipment can identify whether it is a straight handle or a drag handle through the number and position combination of the induction pins on the proximity switch sensing handle on the base, and quickly switch the rehabilitation programs corresponding to different handles. Up to eight rehabilitation programs can be adapted.

[0015] Compared with the prior art, the present invention achieves the following technical results:

[0016] After adopting the structure provided by the present invention, in the final scene of upper limb medical rehabilitation, the device can have greater compatibility and convenience of operation. The user only needs to quickly replace the handle, and the device can automatically switch to the corresponding rehabilitation program. The rehabilitation personnel can directly carry out rehabilitation training, which greatly reduces the user's requirements for the proficiency of the equipment and eliminates tedious and complicated training.
