Description

Retractable caster frame for assisted standing lifts

technical field

The invention belongs to the technical field of medical rehabilitation appliances, in particular to an auxiliary standing lifting machine.

Background technique

Auxiliary standing lift is a short-distance, multi-functional mobile lifting device for patients in homes, hospitals, and nursing homes. It realizes the safe transfer of paralyzed, injured patients or the elderly among beds, wheelchairs, seats, and toilets, greatly reduces the work intensity of nursing staff, improves nursing efficiency, and reduces nursing risks. However, since there is no standard size for medical facilities such as hospital beds and wheelchairs, it is difficult for the assisted standing lift to be applied to all occasions.

Contents of the invention

The object of the present invention is to provide an openable caster frame of an auxiliary standing lift, so as to expand the application range of the auxiliary standing lift.

The technical solution of the present invention is: an openable caster frame for an auxiliary standing shift machine, which includes: an adjustment handle, a connecting plate, a limit plate, a base beam frame, a pull rod and a caster frame;

The two caster frames are respectively hinged on both sides of the base beam frame through rotating shafts; one side of the caster frame is connected to the bottom of the connecting plate through a tie rod, and the caster frame on the other side is connected to the top of the connecting plate through a tie rod; the top of the connecting plate is connected to Adjustment handle;

The limiting plate is fixed in the middle of the base beam frame; the middle of the limiting plate is provided with a chute and three card slots on the left, middle and right;

The connecting plate is located in the chute of the limiting plate; the pin shaft sleeved with the spring passes through the connecting plate and is connected with the beam frame of the base. The pin shaft is the rotation axis of the adjusting handle and the connecting plate; in the chute of the bit plate;

When the handle is adjusted, the connecting plate and the pull rod pull the caster frame to open and close around the rotating shaft; when the handle is manually adjusted so that the connecting plate snaps into the left, middle, and right slots of the limit plate, the caster frame is respectively closed, parallel, and open. state.

Working principle: When it is necessary to adjust the position of the caster frame, the adjustment handle is moved out of the slot of the limit plate, at this time the spring is compressed, after the adjustment handle is placed in the required slot, under the restoring force of the spring , the adjustment handle is fixed and locked in the corresponding position, and at the same time, it plays the role of locking the caster frame, which improves the stability of the equipment.

Beneficial effects: the invention enables the caster frame of the auxiliary standing lift to have three states: closed, parallel, and open, expands the applicable range of the auxiliary standing lift, and can ensure the stability and reliability of the auxiliary standing lift during the moving process.

detailed description

Referring to accompanying drawing 1, an openable caster frame for an auxiliary standing lift includes: an adjustment handle 1, a connecting plate 2, a limit plate 3, a fixing bolt 5, a base beam frame 6, a pull rod 7 and a caster frame 9 ;

The adjustment handle 1 is used to manually adjust the opening and closing of the caster frame 9;

The connecting plate 2 is used to connect the adjusting handle 1 and the pull rod 7, so that the adjusting handle 1 drives the pulling rod 7 to move; Shaft; the limit plate 3 is clamped on the connecting end of the connecting plate 2 and the adjusting handle 1, and is used to limit the pulling range of the adjusting handle 1 and position the connecting plate 2;

The spring 4 is sleeved on the pin shaft on the connecting plate 2, and the two ends are in conflict with the shoulders of the connecting plate 2 and the pin shaft 5 respectively. Disengaged, together with the limit plate 3, it plays the role of locking and limiting;

The caster frame 9 is hinged at both ends of the base beam frame 6, and other structural parts are connected and fixed;

The two ends of the pull rod 7 are respectively connected to the connecting plate 2 and the caster frame 9 through the joint bearing 8, and when the adjustment handle 1 moves, the caster frame 9 is pulled to open and close around the hinge shaft;

The specific connection relationship is: two caster frames 9 are respectively hinged on both sides of the base beam frame 6 through rotating shafts 10; wherein, one side of the caster frame 9 is connected to the bottom of the connecting plate 2 through a pull rod 7, and the other side of the caster frame 9 through Another pull rod 7 links to each other with the top of connecting plate 2;

The limiting plate 3 is fixed on the middle part of the base beam frame 6; the middle part of the limiting plate 3 is provided with a chute and three card slots on the left, middle and right;

The connecting plate 2 is located in the chute of the limiting plate 3;

The pin shaft 5 sleeved with the spring 4 passes through the connecting plate 2 and is connected with the base beam frame 6; the spring 4 presses the connecting plate 2 into the chute of the limiting plate 3;

Referring to accompanying drawings 2 and 3, when the adjustment handle 1 moves, the connecting plate 2 and the pull rod 7 pull the caster frame 9 to open and close around the rotating shaft 10; When the right card slot is in place, the caster frame 9 is in the closed, parallel and open states respectively.

To sum up, the above are only preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
