DETAILED DESCRIPTION
[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example 1
[0027] The preferred embodiment of the synchronous lifting medical transfer machine with easy distance adjustment provided by the utility model is as follows: Figures 1 to 5 As shown: a synchronous lifting medical shift machine which is easy to adjust the distance, includes a base 5, four corners of the bottom end of the base 5 are movably connected with universal wheels 6, a shock absorbing assembly 11 is arranged inside the base 5 at the top of the universal wheel 6, two ends of one side of the top end of the base 5 are fixedly connected with fixing frames 7, a hydraulic cylinder 4 is fixedly connected at the middle position of one side of the top end of the base 5, the output end of the hydraulic cylinder 4 is fixedly connected with a driving seat 8, one side of the driving seat 8 is fixedly connected with a touch screen 3, two ends of the other side of the driving seat 8 are hinged with seat plates 9, and one side of the bottom end of the seat plate 9 is provided with a distance detection assembly 12.
[0028] The distance detection component 12 includes a reserved groove 1202, which is provided on one side of the bottom end of the seat plate 9, and one end of the inner top wall of the reserved groove 1202 is fixedly connected to an infrared laser rangefinder 1203, and the inner top walls of the reserved groove 1202 on both sides of the infrared laser rangefinder 1203 are provided with sliding grooves 1204, and both ends of the inner wall of the sliding groove 1204 are fixedly connected to magnetic blocks 1205, and the interior of the sliding groove 1204 is movably connected to a sliding block 1206, and both ends of the sliding block 1206 are provided with magnetic holes 1207, and one end of the sliding block 1206 is fixedly connected to a protective plate 1208 extending to the outside of the sliding groove 1204, and the sliding block 1206 is used to move in the sliding groove 1204. The protective plate 1208 can slide to open or block the infrared laser rangefinder 1203 by sliding the magnetic block 1205 and the magnetic hole 1207. After the infrared laser rangefinder 1203 is turned on, the infrared laser rangefinder 1203 can be used to detect the distance between the bottom of the seat plate 9 and the top of other platforms, so that the seat plate 9 can reach the optimal height, thereby making the transfer without a sense of drop, thereby improving the user's comfort. When not in use, the protective plate 1208 can be used to block and protect the infrared laser rangefinder 1203 to prevent excessive dust adhesion or external force from scratching the infrared laser rangefinder 1203 and affecting the detection accuracy.
[0029] In this embodiment, a magnetic snap-fit structure is formed between the magnetic block 1205 and the inside of the magnetic hole 1207. The magnetic block 1205 is symmetrically distributed about the transverse center axis of the reserved groove 1202. The magnetic snap-fit between the magnetic block 1205 and the inside of the magnetic hole 1207 is utilized to improve the limiting and fixing stability of the sliding block 1206 after sliding.
[0030] In this embodiment, a sliding structure is formed between the sliding block 1206 and the interior of the sliding groove 1204. The cross-sections of the sliding groove 1204 and the sliding block 1206 are inverted convex. The sliding of the inverted convex sliding block 1206 and the interior of the sliding groove 1204 is utilized to avoid separation between the protective plate 1208 and the reserved groove 1202, and to make the sliding of the protective plate 1208 more stable.
[0031] In this embodiment, anti-slip grooves 1201 are evenly spaced at the bottom of the protective plate 1208, and the cross-sectional area of the protective plate 1208 is larger than the cross-sectional area of the infrared laser rangefinder 1203. The anti-slip grooves 1201 are used to increase the contact friction between the user's fingers and the protective plate 1208, making it more convenient and smooth for the user to push the protective plate 1208. Example 2
[0032] Based on Example 1, a preferred embodiment of the synchronous lifting medical transfer machine that is easy to adjust the distance provided by the utility model is as follows: Figures 1 to 5 As shown: the shock absorbing assembly 11 includes a fixing groove 1106, which is opened at the four corners of the bottom end of the base 5, and the inner top wall of the fixing groove 1106 is fixedly connected with a damper 1101, and the bottom end of the damper 1101 is fixedly connected with a shock absorbing rod 1103 extending to the outside of the base 5, and the bottom end of the shock absorbing rod 1103 is fixedly connected to the top of the universal wheel 6, and the surface of the damper 1101 is wound with a shock absorbing spring 1102, and the top of the shock absorbing spring 1102 is fixedly connected to the inner top wall of the fixing groove 1106. When the universal wheel 6 rolls and generates vibration, the shock absorbing spring 1102 is used to absorb the vibration transmitted by the universal wheel 6, and the damper 1101 is used to consume the elastic potential energy absorbed by the shock absorbing spring 1102, thereby realizing buffering and shock absorption during the transportation of the base 5, reducing the discomfort caused to the user by the vibration during transportation.
[0033] In this embodiment, an auxiliary groove 1105 is opened at an equal angle on the lower end of the inner wall of the fixed groove 1106, and an auxiliary block 1104 that slides with the inside of the auxiliary groove 1105 is fixedly connected at an equal angle to the upper end of the surface of the shock-absorbing rod 1103. The auxiliary block 1104 slides in the auxiliary groove 1105, so that the shock-absorbing rod 1103 can slide up and down more smoothly, and the sliding friction between the two can also consume a part of the elastic potential energy absorbed by the shock-absorbing spring 1102.
[0034] Furthermore, a slide groove 1 is provided on the inner wall of the fixed frame 7, and sliders 2 that slide with the inside of the slide groove 1 are fixedly connected at both ends of the driving seat 8. The sliding of the slider 2 in the slide groove 1 makes the driving seat 8 slide up and down more smoothly, which is convenient for the user to lift or lower.
[0035] In addition, support rods 10 are hinged at both ends of the lower end of one side of the driving seat 8, and the top end of the support rod 10 is fixedly connected to one side of the bottom end of the seat plate 9. The support rod 10 can be used to support the seat plate 9 to improve the structural strength of the seat plate 9 itself.
[0036] The working principle and use process of the utility model are as follows: first, when displacement is required, the protective plate 1208 is pushed first, and the anti-slip pattern 1201 is used to increase the contact friction between the user's finger and the protective plate 1208, so that the protective plate 1208 slides more easily and drives the sliding block 1206 to slide inside the sliding groove 1204 until the infrared laser rangefinder 1203 is fully opened;
[0037] Then the staff rotates the seat plate 9 to open it, and then pushes the base 5 to slide through the handle on the fixing frame 7. At this time, when the universal wheel 6 rolls and generates vibration, the universal wheel 6 moves and drives the shock absorbing rod 1103 to slide inside the fixing groove 1106 to compress the damper 1101 and the shock absorbing spring 1102. At this time, the shock absorbing spring 1102 absorbs the vibration transmitted by the universal wheel 6, and the damper 1101 consumes the elastic potential energy absorbed by the shock absorbing spring 1102, thereby achieving buffering and shock absorption during the transportation of the base 5, reducing the discomfort caused by the vibration during transportation to the user;
[0038] Then, the seat plate 9 is placed at a suitable position for the user, and then the hydraulic cylinder 4 is started to drive the driving seat 8 to descend, thereby causing the seat plate 9 to descend. At this time, the infrared laser rangefinder 1203 is used to detect the distance between the bottom end of the seat plate 9 and the top end of other platforms to avoid a large drop feeling to the user when the seat plate 9 is higher than other platforms, causing discomfort, or the seat plate 9 is not stopped in time during lifting and lowering, resulting in collision with other platforms. At this time, the collision feeling will also cause discomfort to the user and damage the slide 1. Then, the seat plate 9 is closed, and the user sits on the top of the seat plate 9. Then, the hydraulic cylinder 4 is started to make the driving seat 8 rise and drive the seat plate 9 to rise, thereby realizing the lifting action of the user, and then the base 5 is transferred to other platforms. Repeat the above operation to transfer the user to other platforms.
[0039] When not in use, the protective plate 1208 is slid to completely cover the infrared laser rangefinder 1203. At this time, the magnetic block 1205 is engaged with the magnetic attraction inside the sliding block 1206 to achieve limited fixation of the protective plate 1208 after sliding, thereby preventing excessive dust and impurities from adhering to the surface of the infrared laser rangefinder 1203 or scratches caused by external forces, which may affect the accuracy of the infrared laser rangefinder 1203 in detecting distance.
[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
