[0001] This utility model relates to the field of weighing scales, and in particular to a drop-proof weighing scale. Background Technology

[0002] A weighing scale is a device used to weigh a user. The user can weigh themselves by standing on the scale. However, when a weighing scale is used in a senior activity center, it is usually difficult for elderly people in wheelchairs to weigh themselves due to their limited mobility. Therefore, this application provides a drop-proof weighing scale to meet the needs. Summary of the Invention

[0003] This invention provides a drop-proof weighing scale to solve the problem that conventional weighing scales are usually difficult to use to weigh elderly people in wheelchairs.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A drop-proof weighing scale includes a weighing scale body and also includes:

[0006] The anti-fall mechanism includes a seat that is detachably connected to the weighing surface of the scale body. The top of the seat is fixed with a cushion, a fixed armrest, a backrest, and a column. The cushion and backrest are located between the fixed armrest and the column. The fixed armrest is hinged to a movable armrest on its side. The top of the column is provided with a clip for connecting and positioning the movable armrest and the column.

[0007] Preferably, the locking component includes an L-shaped locking strip rotatably connected to the top of the column, and a locking groove is provided at the top of the movable handrail, with the bottom of the vertical section of the L-shaped locking strip locked in the locking groove.

[0008] Preferably, a connecting seat is fixed to the top of the column, and the horizontal end of the L-shaped clip is movably sleeved on the rotating shaft surface fixed to the inner wall of the connecting seat.

[0009] Preferably, the horizontal section of the L-shaped card strip is provided with a protrusion, which is arc-shaped and curved upward.

[0010] Preferably, the vertical section of the L-shaped card strip has a rounded chamfer at its end.

[0011] Preferably, a support block is fixed to the side of the fixed handrail, and the support block fits against the bottom of the movable handrail.

[0012] Preferably, a second support block is fixed to the side of the column, and the second support block is in contact with the bottom of the movable handrail.

[0013] Preferably, curved surfaces are provided at the corner positions of the upper surfaces of both support block one and support block two.

[0014] Compared with the prior art, this utility model has at least the following beneficial effects:

[0015] In the above solution, by setting up an anti-fall mechanism, elderly people in wheelchairs can be lifted onto a seat consisting of a seat, cushion, and backrest, and then weighed. Furthermore, through the design of fixed and movable armrests, the elderly can hold onto the fixed and movable armrests while sitting in the seat to prevent falls.

[0016] By incorporating an L-shaped locking strip and a raised portion, when lifting an elderly person onto the seat, the L-shaped locking strip can be rotated upwards to separate it from the slot. Then, the movable armrest can be rotated to open its position, preventing it from obstructing the lifting of the elderly person and facilitating the process. Once the elderly person is seated, closing the movable armrest and engaging the L-shaped locking strip in the slot prevents it from rotating arbitrarily, ensuring stable protection for the elderly. The raised portion, located on the L-shaped locking strip, allows the L-shaped locking strip to be rotated upwards by gripping it with a finger, facilitating the separation from the slot and further simplifying the opening of the movable armrest.

[0017] By setting support block one and support block two, both of which are supported at the bottom of the movable handrail, the hinge at the connection between the movable handrail and the fixed handrail is prevented from bearing force alone, thereby improving the service life of the hinge.

Detailed Implementation

[0024] The present invention provides a drop-proof weighing scale in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art can also use other alternative methods to implement the invention. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0025] like Figures 1-4 As shown, an embodiment of this utility model provides a drop-proof weighing scale, including a weighing scale body 1, and further comprising:

[0026] The anti-fall mechanism 2 includes a seat 3 detachably connected to the weighing surface of the scale body 1. The top of the seat 3 is fixed with a cushion 4, fixed armrests 6, a backrest 5, and a column 15. The cushion 4 and backrest 5 are located between the fixed armrests 6 and the column 15. Movable armrests 7 are hinged to the sides of the fixed armrests 6. A locking device 8 is provided on the top of the column 15 for connecting and positioning the movable armrests 7 and the column 15. By setting up the anti-fall mechanism 2, the seat 3, cushion 4, and backrest 5 facilitate the lifting of elderly people in wheelchairs or with mobility issues onto the scale for weighing. The design of the fixed armrests 6 and movable armrests 7 provides support for the elderly during weighing, preventing falls. The locking device 8 connects and positions the movable armrests 7 and the column 15, ensuring that the movable armrests 7 can stably perform their protective function, thus improving the safety and adaptability of the scale body 1.

[0027] like Figure 2 and Figure 4 As shown in this embodiment, the locking component 8 includes an L-shaped locking strip 9 rotatably connected to the top of the column 15. The top of the movable armrest 7 has a locking groove 16. The bottom of the vertical section of the L-shaped locking strip 9 is locked in the locking groove 16. When it is necessary to lift the elderly onto the seat, the L-shaped locking strip 9 can be rotated upward to separate it from the locking groove 16, thereby rotating the movable armrest 7 to open its position and preventing the movable armrest 7 from affecting the operation of lifting the elderly. After the elderly sits on the seat, the movable armrest 7 is closed and the L-shaped locking strip 9 is locked in the locking groove 16, which can prevent the movable armrest 7 from rotating at will and ensure that the protective ability of the movable armrest 7 for the elderly is stable.

[0028] like Figure 2 and Figure 4 As shown in this embodiment, a connecting seat 10 is fixed to the top of the column 15, and the horizontal end of the L-shaped locking strip 9 is movably sleeved on the rotating shaft surface fixed to the inner wall of the connecting seat 10. The setting of the connecting seat 10 and the rotating shaft provides a stable rotating connection structure for the L-shaped locking strip 9, so that the L-shaped locking strip 9 can rotate flexibly around the rotating shaft, making it convenient for the operator to rotate the L-shaped locking strip 9 upward or downward, thereby limiting and unlocking the movable handrail 7.

[0029] like Figure 2 and Figure 4 As shown in this embodiment, a protrusion 11 is provided at the horizontal section of the L-shaped card strip 9. The protrusion 11 is manufactured by integral molding. The protrusion 11 is arc-shaped and curved upward. The design of the protrusion 11 makes it easy for the operator to grip this place with their fingers, which facilitates the application of a force to separate the L-shaped card strip 9 from the card slot 16, and further facilitates the opening of the movable handrail 7.

[0030] like Figure 4 As shown in this embodiment, the vertical section of the L-shaped card strip 9 has a rounded chamfer at its end. The rounded chamfer can guide the L-shaped card strip 9 into the card slot 16, thereby facilitating the positioning of the movable handrail 7.

[0031] like Figure 1 and Figure 3 As shown in this embodiment, a support block 12 is fixed to the side of the fixed handrail 6. The support block 12 fits against the bottom of the movable handrail 7. The support block 12 supports the bottom of the movable handrail 7, which can prevent the hinge at the connection between the movable handrail 7 and the fixed handrail 6 from bearing the force alone. During the opening, closing and use of the movable handrail 7, it shares its weight and the pressure generated, effectively extending the service life of the hinge.

[0032] like Figure 2 and Figure 4 As shown in this embodiment, a second support block 13 is fixed to the side of the column 15. The second support block 13 fits against the bottom of the movable handrail 7. The second support block 13 and the first support block 12 work together to support the bottom of the movable handrail 7 from different positions, further dispersing the load on the movable handrail 7, thereby more comprehensively protecting the hinge at the connection between the movable handrail 7 and the fixed handrail 6, greatly improving the durability of the hinge, and ensuring the long-term stable use of the movable handrail 7.

[0033] like Figure 3 and Figure 4 As shown in this embodiment, curved surfaces 14 are provided at the corners of the upper surfaces of support block 12 and support block 2 13. The design of the curved surfaces 14 can reduce the friction between support block 12, support block 2 13 and the bottom of the movable handrail 7, making the movable handrail 7 rotate more smoothly.

[0034] Working principle: When it is necessary to lift an elderly person in a wheelchair onto the weighing scale, the operator first holds the protrusion 11 on the L-shaped locking strip 9 with their fingers. Utilizing its upward curved structure, it is easy to apply force and rotate the L-shaped locking strip 9 upward, so that its vertical section separates from the slot 16 at the top of the movable armrest 7. At this time, the movable armrest 7 loses the restriction of the L-shaped locking strip 9 and can rotate around the hinge point on the side of the fixed armrest 6, opening the movable armrest 7 and avoiding obstructing the operation of lifting the elderly person. Thus, the elderly person can be smoothly lifted onto the seat composed of the seat 3, cushion 4 and backrest 5.

[0035] After the elderly person sits in the seat, the operator rotates the movable armrest 7 back to its original position to put it in a protective state. Then, the L-shaped locking strip 9 is rotated downwards so that its vertical section is re-locked into the locking slot 16. This method fixes the movable armrest 7 and prevents it from rotating randomly, ensuring that the movable armrest 7 can stably play its protective role. Together with the fixed armrest 6, it provides reliable anti-fall support for the elderly person, allowing them to hold onto the fixed armrest 6 and the movable armrest 7 during the weighing process, maintain their body balance, and avoid falling.

[0036] During the use of the movable handrail 7, the support block 12 on the side of the fixed handrail 6 and the support block 2 13 on the side of the column 15 always support the bottom of the movable handrail 7, sharing the weight of the movable handrail 7 and the pressure generated during use. This prevents the hinge at the connection between the movable handrail 7 and the fixed handrail 6 from bearing a large load alone, thus effectively extending the service life of the hinge. Even when the movable handrail 7 is open, the support block 12 still supports the movable handrail 7, preventing the hinge at the connection between the movable handrail 7 and the fixed handrail 6 from bearing a large load alone. In addition, the curved surface 14 at the corner of the upper surface of the support block 12 and the support block 2 13 reduces friction with the bottom of the movable handrail 7, making the movable handrail 7 rotate more smoothly and further improving the user experience. Once the elderly person is seated and holding the handrail firmly, the scale body 1 can weigh them, completing the entire safe weighing process. The weight can be displayed on the pointer dial or digital display screen by a bystander.

[0037] After weighing, the movable armrest 7 is opened, and then the elderly person is lifted from the seat to the wheelchair. Other elderly people can then be weighed again. In addition to being suitable for elderly people in wheelchairs, it is also suitable for elderly people with mobility difficulties, thus improving the adaptability of the scale body 1.

[0038] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
