Description

Technical Field

[0001] The utility model relates to the technical field of patient transfer equipment, in particular to a clamping mechanism with adjustable arm spacing and a hugging type transfer machine. Background Technique

[0002] A transfer machine is a tool for transferring patients. It can lift a patient from a seat, and a caregiver can push the patient to the toilet and gently place the patient on the toilet seat. It can also be used in scenarios such as transferring a patient from a seat to a dining chair where patient transfer is required. This type of equipment is usually driven by an electric push rod to drive a robotic arm, and the robotic arm lifts or lowers the patient.

[0003] Most of the existing transfer machines are basket suspension type. Before lifting, the patient needs to be fixed before lifting, which is rather troublesome to operate and requires removing the straps. Additionally, when the patient is fixed by the straps, the patient cannot be unbuttoned to use the toilet. Another type of transfer machine is a back-hugging type transfer machine with a structure imitating human back-hugging. The back-hugging process is simple. This solution uses a clamping arm with a fixed angle, and the clamping force on the patient is generated by the patient's weight pressing down. The clamping force of this clamping mechanism is completely generated by gravity, that is, the greater the gravity, the greater the clamping force, and the function of adjusting the clamping force cannot be achieved. Since some weak elderly people cannot bear too much clamping force, this type of transfer machine is not suitable for such patients. There are also some transfer machines where the positions of the two axillary support structures (including the left-right spacing and / or the front-back spacing) are fixed. Due to the large differences in the body widths of different people, that is, the widths in the left-right direction and / or the front-back direction of the body, this type of transfer machine has poor applicability and results in a poor user experience. Therefore, it is necessary to develop a new type of clamping mechanism with adjustable arm spacing and a hugging type transfer machine to solve the above problems. Summary of the Utility Model

[0004] Aiming at at least one of the above existing technical problems, the purpose of the utility model is to provide a clamping mechanism with adjustable arm spacing and a hugging type transfer machine.

One end of any one of the connecting rods is hinged to one side of the slider.

[0013] Preferably, the adjusting mechanism further includes an adjusting column protruding outwardly at one end of any one of the adjusting plates away from the other adjusting plate. Adjusting grooves are respectively formed at both ends of the mounting plate and are recessed inwardly and can be clamped with the corresponding adjusting columns.

[0014] Preferably, the locking member is a locking screw. A connecting groove extending along the moving direction of the adjusting plate is formed on one of the mounting plate and any one of the adjusting plates, and a connecting hole matching the locking screw is formed on the other of the mounting plate and any one of the adjusting plates.

[0015] Preferably, any one of the arm components can rotate relative to its corresponding adjusting plate around the connection point of the two.

[0016] Preferably, any one of the arm components includes:

[0017] At least one swing rod, one end of which is hinged to its corresponding adjusting plate and the other end extends toward the side of the adjusting plate away from the other adjusting plate.

[0018] At least one connecting member, one end of any of the connecting members being fixed to the other end of the swing rod and the connecting member extending transversely away from the swing rod in a direction perpendicular to the extending direction of the swing rod;

[0019] A hugging arm, which is fixed to the other end of the corresponding connecting member.

[0020] Preferably, the connecting member is a telescopic link or a cylinder that can telescopically move towards or away from the swing rod.

[0021] Preferably, each hugging arm assembly further includes an arm pad provided on the hugging arm and a chest pad provided on the side of the mounting plate facing the two hugging arm assemblies.

[0022] Preferably, a cover plate is further provided outside the adjusting mechanism to shield the adjusting driving member.

Detailed implementation manners

[0033] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in combination with the specific implementation manners and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0034] A clamping mechanism 100 with adjustable arm spacing according to an embodiment of the present utility model. Specifically, refer to Figures 1 to 4 , mainly including a mounting plate 10, an adjusting mechanism 20 and two arm assemblies 30. The mounting plate 10 is a square plate, arranged vertically. The two opposite surfaces of the mounting plate 10 are also namely as Figure 1The front and back shown are implemented as the front side and the back side respectively. The adjusting mechanism 20 includes two adjusting plates 21, an adjusting driving member 22, and at least two locking members 23. Specifically, the two adjusting plates 21 are disposed opposite to each other and movably on one side of the mounting plate 10 (exemplarily the front side of the mounting plate 10 in the figure, that is, the side facing the patient), that is to say, the two adjusting plates 21 are disposed opposite to each other and movably on the left and right sides of the front side of the mounting plate 10. The adjusting driving member 22 is disposed on the side of the mounting plate 10 where the two adjusting plates 21 are located, that is, the front side of the mounting plate 10 and is located between the two adjusting plates 21. For the adjusting driving member 22, it includes a fixed rod 221 and a sliding member 222. The fixed rod 221 is arranged vertically (that is to say, the axis of the fixed rod 221 is perpendicular to the moving direction of the two adjusting plates 21, and the two adjusting plates 21 move horizontally in the left and right directions) at the middle position of the front side of the mounting plate 10. The sliding member 222 is slidably engaged with the fixed rod 221, that is, the sliding member 222 can slide up and down along the fixed rod 221. The sliding member 222 is hingedly connected to the adjusting plate 21 through a connecting rod 24. That is to say, the sliding member 222 slides up and down along the fixed rod 221 to drive the two adjusting plates 21 to move horizontally left and right. The locking members 23 are respectively connected to the mounting plate 10 and the adjusting plate 21 to fix the adjusting plate 21 at the required position. That is to say, when the adjusting plate 21 is adjusted to an appropriate position, the adjusting plate 21 is fixed to the mounting plate 10 through the locking member 23, so that the adjusting plate 21 will no longer move left and right relative to the mounting plate 10. Regarding the number of the locking members 23, there is no special limitation, and one or more locking members 23 can be provided corresponding to each adjusting plate 21, that is, at least one. The two arm-holding assemblies 30 with arms 32 are arranged in mirror symmetry and are respectively disposed at the ends of the two adjusting plates 21 away from each other, that is to say, the two arm-holding assemblies 30 with arms 32 are arranged on the left and right ends of the mounting plate 10, one on the left and one on the right, and are respectively for the left and right arms of the patient to rest on. Since the arm-holding assembly 30 with arms 32 is connected to the adjusting plate 21, and the adjusting plate 21 can move left and right relative to the mounting plate 10, therefore, the two arm-holding assemblies 30 with arms 32 can also move left and right relative to the mounting plate 10, so as to adjust the distance between the two arm-holding assemblies 30 with arms 32, and further enable the holding mechanism 100 to be adaptively adjusted according to the body types of different patients, improving the applicability of the product. The structure of the adjusting mechanism 20 is simple and has strong practicability.

[0035] Specifically, as Figure 2 and Figure 3As shown in the figure, the upper and lower ends of the fixed rod 221 are respectively fixed to the upper and lower ends of the middle position of the mounting plate 10 through a square fixing block 2211. There is a gap between the fixed rod 221 and the front surface of the mounting plate 10, and they are not in contact with each other, so as to provide for the installation of the sliding member 222 and its up and down sliding along the fixed rod 221. The sliding member 222 includes a square plate-shaped slider 2221 slidably disposed within the gap between the fixed rod 221 and the front surface of the mounting plate 10, and at least one sliding block 2222 (exemplarily, the number of sliding blocks 2222 in the figure is three) with one end fixed to the surface of the slider 2221 facing away from the front surface of the mounting plate 10 and the other end slidably sleeved on the fixed rod 221. The slider 2221 can slide up and down along the axis of the fixed rod 221 under the drive of the sliding block 2222. Each adjusting plate 21 is connected to the slider 2221 through at least one connecting rod 24 (exemplarily two in the figure). Specifically, one end of each connecting rod 24 is hinged to one side edge of the slider 2221, and the other end is hinged to the corresponding side of the adjusting plate 21. By sliding the slider 2221 up and down along the fixed rod 221, the angle between the connecting rod 24 hinged to the slider 2221 and the slider 2221 changes. The change in the angle causes the distance between the connecting rod 24 and the adjusting plates 21 on both sides of it in the horizontal direction to change. Since the other end of the connecting rod 24 is also hinged to the adjusting plate 21, the change in the angle of the connecting rod 24 drives the adjusting plate 21 hinged to it to move horizontally, realizing the left and right sliding of the two adjusting plates 21 on the left and right sides of the fixed rod 221, so that the two arm components 30 respectively connected to the two adjusting plates 21 approach or move away from each other, and further realizing the adjustable distance between the two arm components 30. The structure of the adjusting mechanism 20 is simple and convenient to adjust. The user only needs to slide the slider 2221 up and down along the fixed rod 221. Further preferably, as Figure 4 shown, the slider 2221 is disposed on the front surface of the mounting plate 10. Generally, a chest pad is installed on the front surface of the mounting plate 10 to prevent the chest of the patient from being injured by the adjusting mechanism 20 on the front surface of the mounting plate 10 during use. However, the presence of the chest pad makes it inconvenient for the patient to adjust by himself. Therefore, components for operating and adjusting the adjusting mechanism 20 can be added to the back surface of the mounting plate 10. During use, medical staff or the patient's relatives can operate on the back surface of the mounting plate 10 so that the two arm components 30 can be adjusted adaptively according to the body width of the patient. Specifically, on the surface of one side of the back surface of the mounting plate 10 corresponding to the end of each adjusting plate 21 away from the other adjusting plate 21, there is an outward (that is, as Figure 4The adjusting column 25 that protrudes forward as shown. During adjustment, first adjust the locking member 23 so that it does not lock the adjusting plate 21 and the mounting plate 10. Then, pull or push the corresponding adjusting plate 21 relative to the mounting plate 10 through the adjusting column 25 for adjustment. After the adjustment is completed, lock the adjusting plate 21 and the mounting plate 10 through the locking member 23. Concave adjusting grooves are respectively formed in the left and right side edges of the mounting plate 10. The size of the adjusting groove matches that of the adjusting column 25. The adjusting column 25 is clamped in the corresponding adjusting groove when the two adjusting plates 21 are in the closest position. The setting of the adjusting groove can limit the two adjusting plates 21 when they are in the closest position. When the adjusting groove is clamped in the adjusting groove, it is not limited whether the slider 2221 is at the lowest end of the fixed rod 221. It can be, or it can not be. Preferably, it is.

[0036] For the locking member 23, it can be selected as a conventional locking screw on the existing market. Correspondingly, a connecting groove extending along the moving direction of the adjusting plate 21 is formed in one of the mounting plate 10 and any one adjusting plate 21, and a connecting hole matching the locking screw (i.e., the same inner and outer diameters) is formed in the other of the mounting plate 10 and any one adjusting plate 21. The locking screw passes through the connecting groove and then connects with the connecting hole to realize the locking and fixing of the mounting plate 10 and the adjusting plate 21, or the locking screw passes through the connecting hole and the connecting groove in sequence and then abuts against the bottom of the connecting groove to lock the adjusting plate 21 and the mounting plate 10. In the embodiment of the present utility model, by way of example, as Figure 4 shown, the connecting groove is formed in the mounting plate 10, and the connecting hole is arranged on the adjusting plate 21, that is, the locking screw passes through the connecting groove and then is fixed together with the connecting hole. When adjustment is required, loosen the locking screw so that the outer end of the locking screw does not abut against the upper and lower side walls of the notch of the connecting groove, so as to realize that the adjusting plate 21 and the mounting plate 10 are not in a locked state. When the adjustment is completed, tighten the locking screw so that the outer end of the locking screw abuts against the upper and lower side walls of the notch of the connecting groove.

[0037] For the arm-holding 32 assemblies 30, due to the arrangement of the adjusting mechanism 20, the distance between the two arm-holding 32 assemblies 30 can be adjusted according to the body shape of the patient, so that the holding mechanism 100 can be applicable to patients with different body shapes. The patient can adjust according to his own body shape, so that the two arm-holding 32 assemblies 30 can clamp the patient more appropriately and comfortably. After the distance between the two arm-holding 32 assemblies 30 is adjusted, the adjusting plate 21 and the mounting plate 10 will be locked and fixed by the locking member 23, that is, the positions of the two arm-holding 32 assemblies 30 are fixed, and the clamping force of the two arm-holding 32 assemblies 30 cannot be adjusted during use, so that the use experience of the holding mechanism 100 needs to be further improved. Further preferably, any one of the arm-holding 32 assemblies 30 can rotate relative to its corresponding adjusting plate 21 around the connection point of the two. That is to say, when the patient places his arms on the two arm-holding 32 assemblies 30, the arm-holding 32 assemblies 30 are affected by gravity and move downward and inward, that is, towards the direction of the other arm-holding 32 assembly, so as to stick to the patient's body and hold the patient. That is to say, the patient can adjust the distance between the two arm-holding 32 assemblies 30 through the adjusting mechanism 20 so that the patient can conveniently enter the clamping space between the two arm-holding 32 assemblies 30, and then rely on his own gravity to make the arm-holding 32 assemblies 30 move downward and inward to clamp the patient, so as to prevent the patient from falling backward during the lifting process of the transfer machine, improving the use safety. In this case, the patient does not necessarily adjust the distance between the arm-holding 32 assemblies 30 to correspond to his body width when adjusting. He can first adjust it to be wider than his body width, and then use his weight to rotate the two arm-holding 32 assemblies 30 downward and inward to clamp. This is not only convenient for the patient to enter before use, but also can clamp the patient during use, improving the use safety of the patient. The use is more flexible.

[0038] More specifically, for the arm-holding 32 assemblies 30, since the two arm-holding 32 assemblies 30 are arranged in mirror symmetry, that is, the structures are the same, only one of them will be taken as an example for description in the embodiment of the present invention. As Figure 4 shown, the arm-holding 32 assembly 30 includes at least one swing rod 31, at least one connecting member 33 and an arm-holding 32. One end of any swing rod 31 is hinged to the corresponding adjusting plate 21, and the other end extends towards the side of the adjusting plate 21 away from the other adjusting plate 21. Any connecting member 33 extends transversely in a direction perpendicular to the extending direction of the swing rod 31 and away from the swing rod 31 (that is, as Figure 4As shown from the front to the back, one end of any connecting member 33 is fixed to the other end of the swing rod 31. The swing arm is fixed to the other end of the connecting member 33. The swing arm is a vertically arranged plate for the installation of arm pads, and can be used for the arms or armpits of patients to rest on. Similarly, the swing arm is also arranged with the side of the adjusting plate 21 facing away from the side with the adjusting plate 21 installed on the mounting plate 10, that is, as Figure 1 or Figure 2 shown, extending from the back to the front.

[0039] For the connecting member 33, preferably, as Figure 4 shown, the connecting member 33 is a telescopic connecting rod 24 or a cylinder that can telescopically move towards or away from the swing rod 31. That is to say, the U-shaped clamping space formed by the two hugging arm assemblies 30, the mounting plate 10, and the adjusting mechanism 20 can be adjusted not only in the left-right direction but also in the front-back direction, further improving the applicability and comfort of use.

[0040] According to some preferred embodiments of the present invention, any hugging arm 32 assembly 30 further includes an arm pad (not shown) sleeved on the hugging arm 32 and a chest pad (not shown) sleeved on the front side of the mounting plate 10 facing the two hugging arm 32 assemblies 30, that is, the front of the mounting plate 10. For the arm pad and the chest pad, preferably, they are conventional sponge pads on the existing market. For the shape of the arm pad, it can be selected as U-shaped and directly sleeved on the hugging arm 32. For the shape of the chest pad, it can be selected as L-shaped and directly placed on the front of the mounting plate 10.

[0041] According to some preferred embodiments of the present invention, as Figure 1 shown, since the adjusting mechanism 20 is installed on the front of the mounting plate 10, and the chest pad may not be thick enough, it is possible that when the patient presses on the chest pad, the adjusting mechanism 20 may cause secondary injury to the patient. Therefore, it is necessary to provide a cover plate 40 on the front of the mounting plate 10 to cover the adjusting mechanism 20, more specifically, the adjusting driving member 22. For example, the cover plate 40 is a U-shaped plate. It can not only prevent the adjusting mechanism 20 from causing secondary injury to the patient, but also play a role in protecting the adjusting mechanism 20, preventing foreign objects from entering the adjusting mechanism 20 and causing the adjusting mechanism 20 to jam and unable to be used normally.

[0042] The embodiment of the present invention also provides a hugging type transfer machine, including the clamping mechanism 100 of the above embodiment. Specifically, see Figure 5, including a frame 200, the clamping mechanism 100 of the above embodiment provided at the upper end of the frame 200, and movable walking wheels 300 provided at the bottom end of the frame 200. The clamping mechanism 100 further includes the adjusting mechanism 20 of the above embodiment. As an alternative embodiment, the transfer machine of the embodiment of the present invention further includes a knee pad 500 provided in the middle of the frame 200 and a push-pull grip 400 for the user's handrail provided at the upper end of the frame 200. Since it includes the clamping mechanism 100 of the above embodiment, it at least has the beneficial effects of the clamping mechanism 100 of the above embodiment, and details are not described herein again.

[0043] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
