The clamping mechanism is convenient to use and simple in structure.

Description

Technical Field

[0001] The utility model relates to the technical field of transfer devices, in particular to a clamping mechanism of a transfer machine. Background Art

[0002] A transfer machine can help people with limited mobility to move between a wheelchair and a sofa, a bed, a toilet, a seat, etc., and can also help them solve a series of life problems such as using the toilet and taking a bath.

[0003] The distance or height of the axillary arms on both sides of the chest rest of the existing transfer machine is fixed. When used in a scenario where multiple people share one device (such as a hospital or a nursing home), because the users to be carried vary in body fat and thinness, the distance or height of the axillary arms on both sides of the chest rest is bound to be inapplicable to everyone. Therefore, every time a person is carried, it is necessary to adjust it once, which is very troublesome. And if multiple devices are equipped at the same time for this purpose, the cost is too high.

[0004] Therefore, designing a brand-new clamping mechanism of a transfer machine has become one of the technical problems urgently to be solved in this field. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a clamping mechanism of a transfer machine.

[0006] To achieve the above purpose, the technical scheme adopted by the utility model is specifically as follows:

[0007] A clamping mechanism of a transfer machine includes a chest rest housing, the chest rest housing is in a "T" shape and is a hollow structure; a motor is arranged in the center of the inside of the chest rest housing, and a lead screw is connected to each end of the motor; a clamping arm fixing block is arranged in the inner cavity on each side of the left and right of the chest rest housing, and each lead screw passes through the clamping arm fixing block on the same side and is in threaded transmission; a notch is formed in the front of each side of the left and right of the chest rest housing, a clamping arm is arranged in each notch, and the tail end of each clamping arm is fixedly connected to the clamping arm fixing block on the same side.

[0008] Wherein, the thread directions of the left and right lead screws are opposite.

[0009] Wherein, when the motor rotates forward, the lead screws on both sides can drive the corresponding clamping arm fixing blocks to move inwards; when the motor rotates in reverse, the lead screws on both sides can drive the corresponding clamping arm fixing blocks to move outwards, so as to adjust the distance between the clamping arms during use.

[0010] Wherein, the clamping arm fixing blocks can move left and right in the cavity of the chest rest housing.

[0011] Compared with the prior art, the outstanding effect of the utility model lies in:

[0012] The clamping mechanism of the transfer machine of the present utility model can adjust the distance between the clamping arms at any time. When the motor rotates forward, the lead screws on both sides can drive the clamping arm fixing blocks to move inward; when the motor rotates in reverse, the lead screws on both sides can drive the clamping arm fixing blocks to move outward, so as to adjust the distance between the clamping arms during use. This clamping mechanism is convenient to use and has a simple structure.

[0013] The following further describes the clamping mechanism of the transfer machine of the present utility model with reference to the accompanying drawings and specific embodiments. Description of the Drawings

[0017] Among them, 101 - chest rest outer shell, 102 - clamping arm, 103 - lead screw, 104 - motor, 105 - clamping arm fixing block. Specific Embodiments

[0018] As Figures 1-3 shown, a clamping mechanism of a transfer machine includes a chest rest outer shell 101. The chest rest outer shell 101 is in a "T" shape and is a hollow structure. A motor 104 is provided at the center inside the chest rest outer shell 101, and a lead screw 103 is connected to each end of the motor 104. A clamping arm fixing block 105 is provided in each of the internal cavities on the left and right sides of the chest rest outer shell 101, and each lead screw 103 passes through the clamping arm fixing block 105 on the same side and is driven by a thread. A notch is provided on the front of each of the left and right sides of the chest rest outer shell 101, and a clamping arm 102 is provided in each notch. The tail end of each clamping arm 102 is fixedly connected to the clamping arm fixing block 105 on the same side. The extending direction of the clamping arm 102 is perpendicular to the front of the chest rest outer shell 101. The clamping arm fixing block 105 can move left and right in the cavity of the chest rest outer shell 101.

[0019] The thread directions of the left and right lead screws 103 are opposite. When the motor rotates forward, the lead screws on both sides can drive the corresponding clamping arm fixing blocks to move inward. When the motor rotates in reverse, the lead screws on both sides can drive the corresponding clamping arm fixing blocks to move outward, so as to adjust the distance between the clamping arms during use.

[0020] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. It should not be construed as a limitation of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should fall within the protection scope determined by the claims of the present invention.
