Description

Technical Field

[0001] This utility model relates to the field of bone densitometer technology, specifically to an ultrasonic bone densitometer with protective function. Background Technology

[0002] Bone mineral density, or bone mineral density, is an important indicator of bone quality, reflecting the degree of osteoporosis and serving as a crucial basis for predicting fracture risk. Measuring bone mineral density requires a bone densitometer; currently, the main types of bone densitometers are dual-energy X-ray absorptiometry (DXA) and ultrasound absorptiometry.

[0003] The patent database discloses an ultrasonic bone densitometer (authorization announcement number CN214761177U), comprising: a main frame, wherein the main frame comprises, from bottom to top, a chassis, a horizontally arranged computer host housing, a horizontally arranged bone densitometer host housing, and a monitor stand; a computer host, which is placed in the computer host housing, and the side of the computer host housing facing the operator has a notch; a bone densitometer host, which is placed in the bone densitometer host housing, the lower surface of the bone densitometer host housing is connected to the upper surface of the computer host housing via a column, and the upper surface of the bone densitometer host housing is fixedly connected to the lower surface of the monitor stand; a printer, which is placed on the upper surface of the computer host housing; and a monitor, which is placed on the monitor stand, and the monitor stand also has a keyboard and a mouse, and a bracket holding an ultrasonic detection probe and coupling agent is fixedly connected to one side of the monitor stand.

[0004] The aforementioned bone densitometer is secured by a slot A on the top side of the monitor stand that matches the bottom of the monitor, thus preventing the monitor from falling and providing protection. However, most ultrasonic bone densitometers typically connect their ultrasonic probes to the ultrasonic probe port on the main unit of the bone densitometer via a connector cable. In use, if the user pulls the cable suddenly without paying attention, the connector may separate from the ultrasonic probe port, or the cable may become taut and damaged. The aforementioned device lacks a structure to prevent the connector from falling off and to protect the connecting cable, making it inconvenient to use and relatively impractical. Utility Model Content

[0005] The purpose of this invention is to provide an ultrasonic bone densitometer with protective function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an ultrasonic bone densitometer with protective function, including a first container, with universal wheels symmetrically arranged at the bottom of the first container, a second container on the top of the first container, a computer host housed in the first container, an ultrasonic bone densitometer host housed in the second container, a placement platform on the top of the second container, and a display above the placement platform, a fixing groove adapted to the base of the display on one side of the top of the placement platform, a keyboard movably mounted on one side of the top of the placement platform, a movable plate on one side wall of the placement platform, and a mouse mounted on the movable plate, a hanging ear on one side of the placement platform, and hanging ear slots symmetrically arranged on the hanging ear, with an ultrasonic probe and an ultrasonic transducer respectively installed in the two hanging ear slots. The device includes a coupling agent. One side of the second accommodating body has an ultrasonic probe port. The lower end of the ultrasonic probe is connected to a connecting wire with a connector, and the connector is connected to the ultrasonic probe port. One side of the second accommodating body has a mounting plate. One side of the mounting plate has a protective mechanism connected to the connecting wire. The protective mechanism includes a buffer box, which is fixedly installed on one side of the mounting plate. One side of the buffer box has a cover plate, which is connected to the buffer box via a fixing mechanism. Both ends of the buffer box have wire-locking openings. Inside the buffer box, on the left and right sides respectively, are buffer components one and two arranged in reverse order, and buffer components one and two have the same structure. Inside the buffer box, on the side of buffer component two away from buffer component one, a guide wheel two is rotatably installed.

[0007] Furthermore, the protective mechanism also includes a limiting sleeve, which is fixedly fitted onto the outside of the connecting line and located on the side of the buffer box near the second accommodating body. Positioning blocks are symmetrically arranged on the outside of the limiting sleeve, with the lower positioning block fixedly connected to the buffer box. Each of the two positioning blocks has a locking block on its opposing inner wall. The outer wall of the limiting sleeve has symmetrically opened slots that fit the locking blocks. A support rod is connected to the top of the upper positioning block, and the upper end of the support rod is fixedly connected to the cover plate. The first buffer assembly includes a sliding rod, which is fixedly installed inside the buffer box. A slider is slidably fitted onto the upper outer side of the sliding rod, and a guide wheel is rotatably mounted on one side of the slider. Furthermore, the first guide wheel is located below the connecting line, and the outer side of the slide rod is fitted with a spring below the slider. The first guide wheel in the second buffer assembly is located above the connecting line, and the second guide wheel is located below the connecting line. The protective mechanism is designed so that when the connecting line is accidentally pulled, the connecting line will exert force on the two first guide wheels, thereby driving the slider to slide and squeeze the first spring. The elasticity of the first spring is used to buffer the force on the connecting line, thereby avoiding damage to the connecting line due to sudden pulling. In conjunction with the use of the limiting sleeve, positioning block, and locking block, the connecting line can be limited to prevent the connector from being pulled off. It is convenient to use and more practical.

[0008] Furthermore, the fixing mechanism includes a connecting seat, which is symmetrically arranged on the upper and lower sides of the buffer box and fixedly connected to the mounting plate. A U-shaped frame is symmetrically fitted on the outer side of the cover plate, and the two ends of the U-shaped frame are respectively inserted into the insertion holes opened at one end of the connecting seat. A transmission rod is provided on the side of the connecting seat away from the buffer box. A handle is connected to one end of the transmission rod outside the connecting seat. A locking rod is provided on the right side of the U-shaped frame at the bottom of the transmission rod. A limiting groove adapted to the locking rod is opened on one side of the U-shaped frame. A fixing block two is provided between the inner bottom surface of the connecting seat and the transmission rod, and the fixing block two is fixedly connected to the connecting seat. A guide rod is fixedly connected to one side of the fixing block two. A fixing block one is fitted on the outer side of the guide rod and fixedly connected to the transmission rod. A spring two is fitted on the outer side of the guide rod between the fixing block one and the fixing block two. The fixing mechanism allows for convenient and quick connection and disassembly between the cover plate and the buffer box, and facilitates the installation and removal of the connecting wire.

[0009] Furthermore, both guide wheels one and two are I-shaped, and the connecting shafts of guide wheels one and two are rotatably connected to the slider and the buffer box respectively through bearings. The two ends of spring one are fixedly connected to the inner walls of the slider and the buffer box respectively, so as to guide and limit the connecting line.

[0010] Furthermore, the transmission rod is U-shaped, and the first and second fixing blocks are located between the left and right U-shaped frames. The two ends of the second spring are fixedly connected to the first and second fixing blocks respectively, so as to connect with the cover plate and limit its movement.

[0011] Furthermore, the limiting sleeve is made of rubber, the locking block has a semi-circular structure, and several rolling balls are movably embedded in the inner wall of the locking port to protect and limit the connecting wire. The rolling balls reduce the friction between the connecting wire and the locking port, thus reducing wear on the connecting wire.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] This utility model, through its protective mechanism, can cause the connecting wire to drive two limiting sleeves to move the slider on the slide rod and compress the spring when the connecting wire is subjected to a sudden pulling force. This utilizes the deformation of the spring to offset and buffer the force, preventing damage to the connecting wire. At the same time, the limiting sleeves, positioning blocks, and locking blocks limit the connecting wire, preventing the connector from separating from the ultrasonic probe socket and affecting its use. This provides protection for the connecting wire, making it convenient to use and more practical.

[0014] This utility model, through a fixing mechanism, allows for convenient and quick connection and fixation or disassembly between the cover plate and the buffer box, facilitating the installation and removal of connecting wires, and also making it convenient for the maintenance and repair of components inside the buffer box.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 - Figure 6The illustrated ultrasonic bone densitometer with protective function includes a housing 1. The bottom of housing 1 is symmetrically equipped with casters. A second housing 2 is located on top of housing 1. Housing 1 houses a computer host, and housing 2 houses the ultrasonic bone densitometer host. In this example, a printer (not shown) is located on one side of housing 2 on top of housing 1. A platform 3 is located on top of housing 2, and a monitor 4 is located above the platform 3. A fixing groove for the base of the monitor 4 is located on one side of the top of the platform 3. A keyboard is movably mounted on one side of the top of the platform 3. A movable plate with a mouse is located on one side wall of the platform 3. A hanging ear 5 is located on one side of the platform 3, and hanging ear slots are symmetrically arranged on the hanging ear 5. An ultrasonic probe 6 and an ultrasonic transducer 6 are respectively installed in the two hanging ear slots. The coupling agent 7 and the second container 2 have an ultrasonic probe socket on one side. The lower end of the ultrasonic probe 6 is connected to a connecting line 11 with a connector, and the connector is connected to the ultrasonic probe socket. The second container 2 has a mounting plate 8 on one side. The mounting plate 8 has a protective mechanism connected to the connecting line 11 on one side. The protective mechanism includes a buffer box 9, which is fixedly installed on one side of the mounting plate 8. The buffer box 9 has a cover plate 10 on one side, which is connected to the buffer box 9 through a fixing mechanism. Both ends of the buffer box 9 have wire-locking openings. The buffer box 9 has a buffer component 12 and a buffer component 2 13 arranged in reverse order on the left and right sides, respectively. The buffer component 12 and the buffer component 2 13 have the same structure. The second guide wheel 18 is rotatably installed on the side of the buffer component 2 13 away from the buffer component 12 inside the buffer box 9. In this example, the protective mechanism also includes a limiting sleeve 19, which is fixedly sleeved on the outside of the connecting line 11 and located on the side of the buffer box 9 near the second accommodating body 2. Positioning blocks 20 are symmetrically arranged on the outside of the limiting sleeve 19, and the lower positioning block 20 is fixedly connected to the buffer box 9. Each of the two positioning blocks 20 has a locking block 21 on its opposite inner wall. The outer wall of the limiting sleeve 19 has symmetrically opened slots that fit the locking blocks 21. A support rod 22 is connected to the top of the upper positioning block 20, and the upper end of the support rod 22 is fixedly connected to the cover plate 10. The first buffer assembly 12 includes a sliding rod 14, which is fixedly installed inside the buffer box 9. A slider 15 is slidably sleeved on the upper outer side of the sliding rod 14. A guide wheel 16 is rotatably mounted on one side of the slider 15. 16 is located below the connecting line 11. A spring 17 is sleeved on the outside of the slide bar 14 below the slider 15. The guide wheel 16 in the buffer assembly 2 13 is located above the connecting line 11, and the guide wheel 2 18 is located below the connecting line 11. The protective mechanism is designed so that when the connecting line 11 is accidentally pulled, the connecting line 11 will exert force on the two guide wheels 16, thereby driving the slider 15 to slide and squeeze the spring 17. The elastic force of the spring 17 is used to buffer the force on the connecting line 11, thereby avoiding damage to the connecting line 11 due to sudden pulling. In conjunction with the use of the limiting sleeve 19, positioning block 20, and locking block 21, the connecting line 11 can be limited to prevent the connector from being pulled off. It is convenient to use and more practical.In this example, the fixing mechanism includes a connecting seat 23, which is symmetrically arranged on the upper and lower sides of the buffer box 9 and is fixedly connected to the mounting plate 8. A U-shaped frame 25 is symmetrically fitted on the outer side of the cover plate 10. Both ends of the U-shaped frame 25 are inserted into insertion holes at one end of the connecting seat 23. A transmission rod 24 is provided inside the connecting seat 23 on the side away from the buffer box 9. One end of the transmission rod 24 is connected to a handle outside the connecting seat 23. A locking rod 26 is provided at the bottom of the transmission rod 24 on the right side of the U-shaped frame 25. A fitting for the locking rod 26 is provided on one side of the U-shaped frame 25. The limiting groove has a fixing block 29 between the inner bottom surface of the connecting seat 23 and the transmission rod 24, and the fixing block 29 is fixedly connected to the connecting seat 23. A guide rod 28 is fixedly connected to one side of the fixing block 29. A fixing block 27 is sleeved on the outside of the guide rod 28, and the fixing block 27 is fixedly connected to the transmission rod 24. A spring 30 is sleeved on the outside of the guide rod 28 between the fixing block 27 and the fixing block 29. The setting of the fixing mechanism can facilitate the connection and disassembly between the cover plate 10 and the buffer box 9, and facilitate the installation and removal of the connecting wire 11.

[0025] In this example, both guide wheel 16 and guide wheel 18 are I-shaped. The connecting shafts of guide wheel 16 and guide wheel 18 are rotatably connected to slider 15 and buffer box 9 respectively through bearings. The two ends of spring 17 are fixedly connected to the inner walls of slider 15 and buffer box 9 respectively to guide and limit the connecting line 11. In this example, the transmission rod 24 is U-shaped. Fixing block 1 27 and fixing block 29 are located between the left and right U-shaped frames 25. The two ends of spring 2 30 are fixedly connected to fixing block 1 27 and fixing block 29 respectively to connect with cover plate 10 and limit its movement. In this example, the limiting sleeve 19 is made of rubber, and the locking block 21 has a semi-circular structure. Several rolling balls are movably embedded in the inner wall of the locking port to protect and limit the connecting line 11. The rolling balls reduce the friction between the connecting line 11 and the locking port, reducing wear on the connecting line 11.

[0026] The working principle of this utility model is as follows: In use, the connecting wire 11 passes above the guide wheel 16 in the buffer assembly 12, below the guide wheel 16 in the buffer assembly 23, and above the guide wheel 18. The guide wheel 18 is then installed inside the positioning block 20 connected to the buffer box 9. The locking block 21 connected to the positioning block 20 at the lower position is inserted into the corresponding slot at the bottom of the limiting sleeve 19. Then, the cover plate 10 is installed. Before installing the cover plate 10, the handle is pulled to move the transmission rod 24, causing the transmission rod 24 to drive the locking rod 26. At the same time, the transmission rod 24 will... The first fixing block 27 slides along the guide rod 28, and in conjunction with the second fixing block 29, it presses against the second spring 30 until the locking rod 26 moves to the right side of the insertion hole. Then, the cover plate 10 can be installed, allowing both ends of the U-shaped frame 25 to be inserted into the corresponding insertion holes. Simultaneously, the cover plate 10 will move the support rod 22 and the positioning block 20 connected to one end of the support rod 22, causing the positioning block 20 to cover the outside of the limiting sleeve 19. The locking block 21 on the inner wall of the positioning block 20, connected to the support rod 22, will then engage with the slot on the top wall of the limiting sleeve 19, achieving limiting and fixing at the limiting sleeve 19. At the same time, both ends of the U-shaped frame 25 are completely fixed. The handle is fully inserted into the connector 23, and then the pulling force applied to the handle can be released. This allows the fixing block 27 to move the transmission rod 24 back to its original position under the elastic force of the spring 30. The transmission rod 24 then moves the locking rod 26 synchronously, causing the locking rod 26 to engage in the limiting groove on the U-shaped frame 25, thus fixing and restricting the U-shaped frame 25. This completes the installation of the cover plate 10. To remove the cover plate 10, simply pull the handle again and repeat the above steps to remove the cover plate 10. When the connecting wire 11 is accidentally subjected to pulling force, the connecting wire 11 can be synchronously squeezed and pushed to buffer the movement. The movement of guide wheel 16 in component 12 and buffer component 2 13 causes the connected slider 15 to slide along the slide rod 14 and compress spring 17. The elastic force generated by the deformation of spring 17 will offset and buffer the force on the connecting wire 11, thereby preventing damage to the connecting wire 11. At the same time, the limiting sleeve 19, positioning block 20 and locking block 21 limit the position of the limiting sleeve 19, preventing it from being suddenly subjected to force and causing the connector at one end of the connecting wire 11 to separate from the ultrasonic probe socket, thus affecting its use. It can play a protective role for the connecting wire 11 and has a stronger practicality.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
