Description

Technical Field

[0001] The utility model relates to the technical field of electronic platform scales, in particular to a medical high-precision electronic platform scale. Background Art

[0002] An electronic platform scale is a weighing device installed or placed on the ground, which is widely used in many fields such as industry, commerce, transportation or medical treatment. An electronic platform scale, also known as a platform scale, mainly consists of a load-bearing force transmission mechanism, namely a scale body, a high-precision weighing sensor, a weighing display instrument and other main components.

[0003] The working principle of an electronic platform scale is mainly based on the principle of strain electrical measurement. Specifically, when the object or person to be weighed is placed on the carrier tabletop, the gravity is transmitted to the weighing sensor through the carrier, causing the elastic body of the weighing sensor to deform. This deformation causes the strain gauge bridge circuit attached to the elastic body to lose balance, and then outputs an electrical signal proportional to the weight value. These electrical signals are amplified by a linear amplifier, converted into digital signals by A / D, and then processed by the microprocessor of the instrument, and finally displayed on the interface of the display as required.

[0004] With the increase of market demand, medical electronic platform scales have more and more extensive application requirements. Based on this, Chinese Patent CN211855536U discloses a medical electronic scale with dynamic QR code payment, which includes an electronic scale body. Fixed support feet are fixedly installed at the four corner positions on the lower surface of the electronic scale body. A connection structure is installed on the electronic scale body. An installation column is fixedly installed on the connection structure. An adjustment mechanism is installed at the end of the installation column. A device shell is installed on the adjustment mechanism. A display screen is fixedly installed on the front surface of the device shell. Body fat measurement handles are fixedly installed on both side surfaces of the device shell. The installation support is fixedly installed at one end of the installation column. The installation bolt is fixedly installed on the surface of the electronic scale body. This medical electronic scale with dynamic QR code payment can adjust the use angle of the display screen through the adjustment mechanism, and at the same time, the whole device can be quickly disassembled, reducing the volume of the device and facilitating transportation.

[0005] However, the above-mentioned disclosed medical electronic scale still has the technical problem of inconvenient use. Specifically, as a weighing device dedicated to the medical industry, a medical electronic platform scale needs to have a series of unique characteristics and functions to meet the specific needs of hospitals and clinics. Currently, medical electronic platform scales are widely used in various departments of hospitals and clinics, such as internal medicine, surgery, dialysis rooms, etc. It can not only be used to measure the weight of patients, but also be used to monitor and evaluate the nutritional status and treatment effect of patients.

[0027] Please refer to Figures 1 to 4 , a medical high-precision electronic weighing scale of the present utility model includes: a bearing housing 1, a support keel structure 2, a weighing sensor unit 3, an auxiliary weighing structure 4, a vertical rod structure 5 and a main control module 6; the support keel structure 2 is arranged in the bearing housing 1, and the weighing sensor unit 3 is arranged at the bottom of the support keel structure 2; the auxiliary weighing structure 4 is arranged at the end side of the bearing housing 1, and the auxiliary weighing structure 4 is movably connected to the bearing housing 1; the vertical rod structure 5 is arranged at the other end side of the bearing housing 1 relative to the auxiliary weighing structure 4; the main control module 6 is movably arranged at the top of the vertical rod structure 5, and the weighing sensor unit 3 is electrically connected to the main control module 6.

[0028] Specifically, when a medical high-precision electronic weighing scale of the present utility model is in the working process, the item or person to be weighed is placed on the bearing housing 1; the weight borne by the bearing housing 1 is evenly transmitted to the support keel structure 2, and then the weight is transmitted to the weighing sensor unit 3 by the support keel structure 2. This will cause the elastic body of the induction module in the weighing sensor unit 3 to deform, and this deformation will drive the strain gauge bridge circuit attached to the elastic body to lose balance, and then output an electric signal proportional to the weight value. These electric signals are amplified by a linear amplifier and converted into digital signals through A / D conversion; then they are sent to the microprocessor in the main control module 6 for processing, and finally the weighing result is displayed. Further, when it is applied in medical and other fields, the auxiliary weighing structure 4 can move out from the end side of the bearing housing 1 for some special purposes, such as a person in a wheelchair can be towed together with the wheelchair from the auxiliary weighing structure 4 onto the bearing housing 1; then the above-mentioned weighing process is repeated. It can be seen that a medical high-precision electronic weighing scale of the present utility model can improve the user's convenience in some usage scenarios.

[0029] Further, the auxiliary weighing-on structure 4 includes a guiding inclined surface structure 401, an extending connection structure 402, a moving slider 403, a guiding track 404, a moving driving unit 405, and an auxiliary pushing structure 406. The guiding inclined surface structure 401 is movably arranged at one end side of the bearing housing 1, and the guiding inclined surface structure 401 is connected to the extending connection structure 402, and the extending connection structure 402 is arranged in the bearing housing 1. A plurality of the moving sliders 403 are evenly arranged on both sides of the extending connection structure 402, and two guiding tracks 404 are oppositely arranged on both inner cavity side walls of the bearing housing 1, and a plurality of the moving sliders 403 are movably connected to each guiding track 404. The moving driving unit 405 is arranged below the supporting keel structure 2, and the moving driving unit 405 is drivingly connected to the extending connection structure 402.

[0031] Specifically, when the moving driving motor 405a is powered on and started, it can drive the moving driving lead screw 405b to rotate forward or backward. When the moving driving lead screw 405b rotates forward or backward, the moving driving nut block 405c connected thereto can reciprocate along the moving driving lead screw 405b. Thereafter, the moving driving nut block 405c can drive the extending connection structure 402, and then drive the guiding inclined surface structure 401 to extend out of or retract into the bearing housing 1, so as to realize the functions of being convenient for storage and application.

[0032] Further, the main control module 6 is provided with a display unit 601, a control unit 602, a swing support 603, a swing chute 604, a swing rotating shaft 605 and a tightening member 606; the display unit 601 is arranged on the side of the control unit 602, the swing support 603 is arranged at the lower part of the control unit 602, and the swing chute 604 is arranged in the swing support 603; the swing rotating shaft 605 is respectively connected to the vertical rod structure 5 and the swing support 603, and the tightening member 606 is connected to the vertical rod structure 5 through the swing chute 604.

[0033] Specifically, the display unit 601 is used to display the weighing data processed by the control unit 602. The swing support 603 arranged at the bottom of the control unit 602 is hinged to the vertical rod structure 5 through the swing rotating shaft 605; thus, the main control module 6 can conveniently adjust the visible angle. When the visible angle needs to be adjusted, only need to loosen the tightening member 606, and make the swing support 603 slide along the limit of the swing rotating shaft 605 so that the tightening member 606 slides through a preset angle in the swing chute 604, and then tighten the tightening member 606.

[0034] In summary, a medical high-precision electronic weighing scale of the present utility model is respectively provided with a bearing housing 1, a supporting keel structure 2, a weighing sensor unit 3, an auxiliary weighing structure 4, a vertical rod structure 5 and a main control module 6; the supporting keel structure 2 is arranged in the bearing housing 1, and the weighing sensor unit 3 is arranged at the bottom of the supporting keel structure 2; the auxiliary weighing structure 4 is arranged at the end side of the bearing housing 1, and the auxiliary weighing structure 4 is movably connected to the bearing housing 1; the vertical rod structure 5 is arranged at the other end side of the bearing housing 1 relative to the auxiliary weighing structure 4; the main control module 6 is movably arranged at the top of the vertical rod structure 5, and the weighing sensor unit 3 is electrically connected to the main control module 6.
