[0024] The application will be further described below in conjunction with the drawings and embodiments. It is particularly pointed out that the following embodiments are only for illustrating the application, but not for limiting the scope of the application. Similarly, the following embodiments are only part of the embodiments of the application, not all the embodiments of the application, and all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the application.
[0025] In the description of the application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise explicitly and specifically limited. The terms "first", "second", "third" in the embodiments of the application are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second", "third" can be explicitly or implicitly included at least one of the features. All directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the application are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications also change accordingly. The terms "include" and "have" and any variations thereof in the embodiments of the application are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device including a series of steps or units is not limited to the listed steps or units, but can optionally include steps or units not listed, or can optionally include other steps or components inherent to the process, method, product or device.
[0026] In this paper, the phrase "embodiment" means that the specific features, structures or properties described in conjunction with the embodiment can be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0027] The application provides a medical trolley. Please refer toFigures 1-4 The medical trolley 100 has a height direction, which can be the vertical direction of the medical trolley 100 in use. Exemplarily, the height direction can be the Z-axis direction in Figure 1 The medical trolley 100 can include a support assembly 10, a load assembly 20, and a storage assembly 30. The support assembly 10 is used to provide support for other components. The support assembly 10 includes at least one support column 11 extending along the height direction. The support column 11 can be one, two, three, or more. The load assembly 20 includes a load panel 21 and a locking fitting 22 arranged on the load panel 21. The load panel 21 is connected to the support column 11. The normal direction of the load panel 21 can be along the height direction. When the support column 11 is more than one, the load panel 21 is respectively connected to each support column 11, thereby connecting the plurality of support columns 11 into a whole, so that the medical trolley 100 has better integrity. The load panel 21 can be used to place articles. The load assembly 20 can be one or more. When the load assembly 20 is more than one, the plurality of load panels 21 are arranged along the height direction.
[0028] When the number of support columns 11 is greater than or equal to three, the plurality of support columns 11 can be arranged along the outer periphery of the load panel 21, so that the lower ends of the plurality of support columns 11 form a plane, thereby providing stable support for other components. When the number of support columns 11 is less than three, the lower end of the support column 11 can be provided with a base 12, as shown in Figure 1 to enhance the stability of the support column 11. The lower part of the base 12 can also be provided with a plurality of rollers 13 to facilitate the movement of the medical trolley 100.
[0029] Referring to Figure 2 The storage assembly 30 includes a housing 31 and a locking piece 32 arranged on the housing 31. The housing 31 is provided with a storage cavity 311 for accommodating articles. The housing 31 is slidably mounted on the lower part of the load panel 21. The storage cavity 311 has an open state and a closed state. When the storage cavity 311 is in the open state, part or all of the storage cavity 311 is exposed to the load panel 21, at which time articles can be stored in or taken out of the storage cavity 311. When the storage cavity 311 is in the closed state, the load panel 21 covers the storage cavity 311, and the locking piece 32 can cooperate with the locking fitting 22 to limit the sliding of the housing 31, thereby locking the housing 31. Through the sliding of the housing 31 relative to the load panel 21, the storage cavity 311 can be converted between the open state and the closed state. The storage assembly 30 can be one or more. That is, one of the load panels 21 can be provided with the housing 31, or each of the load panels 21 can be provided with the housing 31.
[0030] The locking member 32 can be integrally formed with the housing 31, or the locking member 32 can be assembled with the housing 31. Similarly, the locking matching member 22 can be integrally formed with the bearing panel 21, or the locking matching member 22 can be assembled with the bearing panel 21. The position of at least one of the locking member 32 and the locking matching member 22 is adjustable. That is, the locking member 32 is assembled with the housing 31, and the position of the locking member 32 on the housing 31 can be adjusted during assembly; or, the locking matching member 22 is assembled with the bearing panel 21, and the position of the locking matching member 22 on the bearing panel 21 can be adjusted during assembly; or, the locking member 32 is assembled with the housing 31, and the locking matching member 22 is assembled with the bearing panel 21, and the position of the locking member 32 on the housing 31 can be adjusted during assembly, and the position of the locking matching member 22 on the bearing panel 21 can be adjusted during assembly. In this way, the installation position of the locking member 32 or the locking matching member 22 can be adjusted during assembly of the medical cart 100, so that the bearing panel 21 can be aligned with the housing 31 when the bearing panel 21 covers the storage cavity 311, thereby reducing the gap between the bearing panel 21 and the housing 31, and reducing the impact of the gap on the appearance of the cart.
[0031] The housing 31 has a sliding-out direction and a sliding-in direction. The sliding-out direction is the sliding direction of the housing 31 when the storage cavity 311 is switched from the closed state to the open state. Correspondingly, the sliding-in direction is the sliding direction of the housing 31 when the storage cavity 311 is switched from the open state to the closed state. Exemplarily, the sliding-out direction can be the positive direction of the Y-axis in the X-Y coordinate system, and the sliding-in direction can be the negative direction of the Y-axis in the X-Y coordinate system. Figure 1 Figure 1 Because the opening and closing frequency of the housing 31 is high, after being used for a period of time, the related components are prone to wear, causing the gap between the components to increase, and then a large gap appears on the outer surface of the cart, which affects the appearance of the cart. In an embodiment, the medical cart 100 further comprises a pre-tightening assembly 40 for providing a pre-tightening force to the housing 31. The pre-tightening assembly 40 can be installed on the support column 11, the bearing panel 21, or the housing 31. The pre-tightening force can act on the housing 31 to limit the movement of the housing 31. When the storage cavity 311 is in the closed state, the pre-tightening force provided by the pre-tightening assembly 40 is in the sliding-out direction. When the storage cavity 311 is in the closed state, the pre-tightening force is arranged in the sliding-out direction. On the one hand, the pre-tightening force can limit the movement of the housing 31 towards the sliding-in direction, so that the housing 31 and the bearing panel 21 remain relatively fixed, preventing the housing 31 from shifting, thereby maintaining a small gap between the bearing panel 21 and the housing 31, and reducing the impact of the gap on the appearance of the cart. On the other hand, when the storage cavity 311 is switched from the closed state to the open state, that is, when the storage cavity 311 is opened, the pre-tightening force can push the housing 31 to move towards the sliding-out direction, thereby facilitating the opening of the housing 31.
[0032] The shell 31 can be substantially cuboid. Please refer to Figure 3 The shell 31 has a first face 312 at the front end in the sliding-out direction, and a second face 313 opposite to the first face 312. The first face 312 can be the face of the shell 31 facing the user during use. The storage assembly 30 includes first rails 23, two first rails 23 are respectively arranged at the lower part of the bearing panel 21, and the two sides of the shell 31 perpendicular to the sliding-out direction are respectively connected with the first rails 23 in sliding mode. The two sides of the shell 31 can be provided with rollers, and the shell 31 is connected with the first rails 23 in sliding mode through the rollers. Alternatively, the storage assembly 30 includes second rails 33, two second rails 33 are respectively arranged at the two sides of the shell 31 adjacent to the first face 312, and each second rail 33 is connected with the corresponding first rail 23 in sliding mode, so that the second rail 33 can slide relative to the first rail 23, and thus the shell 31 can slide relative to the bearing panel 21.
[0033] The first rails 23 and the second rails 33 can be directly connected, for example, one of the first rails 23 and the second rails 33 can be provided with a sliding groove, and the other is provided with a flange, and the flange is accommodated in the sliding groove. Alternatively, as shown in Figure 4 In an embodiment, the bearing assembly 20 further includes a rail support 24, the rail support 24 is connected with the first rails 23, and the first rails 23 are connected with the second rails 33 through the rail support 24. The rail support 24 and the first rails 23, and the rail support 24 and the second rails 33 can also be provided with balls to reduce the resistance when the two rails slide relative to each other. By providing the rail support 24, the sliding stroke between the second rail 33 and the first rail 23 can be increased, so that the sliding stroke can be greater than the length of the first rail 23 or the second rail 33.
[0034] In an embodiment, as shown in Figure 3 Figures 5-7 The pre-tightening assembly 40 includes an elastic rod 41. The elastic rod 41 can be rod-shaped, and the extension direction of the elastic rod 41 can be parallel to the sliding direction of the shell 31. When subjected to external action, the elastic rod 41 can be compressed to produce elastic deformation and generate a reaction force on the force applying body; when the external action is removed, the elastic deformation of the elastic rod 41 recovers, and the elastic rod 41 can push the force applying body to move. The elastic rod 41 is installed on the bearing panel 21 or the shell 31. That is, the elastic rod 41 can be installed on the bearing panel 21 or the shell 31. When the storage cavity 311 is in the closed state, the bearing panel 21 or the shell 31 compresses the elastic rod 41 to generate a pre-tightening force, thereby limiting the shell 31 from sliding towards the sliding-in direction. When the storage cavity 311 is opened, the elastic deformation of the elastic rod 41 recovers, and the elastic rod 41 can push the shell 31 to move towards the sliding-out direction, thereby facilitating the opening of the shell 31.
[0035] The elastic rod 41 can act on the side where the first face 312 of the shell 31 is located, or can act on the two sides adjacent to the first face 312, or can act on the side where the second face 313 is located. For example, a baffle is arranged at the lower part of the bearing panel 21 close to the second face 313, one end of the elastic rod 41 is mounted on the baffle, and the other end of the elastic rod 41 can act on the second face 313 of the shell 31.
[0036] The elastic rod 41 can be directly mounted on the bearing panel 21, or can be mounted on the bearing panel 21 through other components. Please refer to Figures 5-7 In an embodiment, the pre-tightening assembly 40 includes a mounting member 42, and the elastic rod 41 is mounted on the bearing panel 21 through the mounting member 42. The mounting member 42 is two, and the two mounting members 42 are respectively arranged at the two sides of the lower part of the bearing panel 21. One end of the mounting member 42 is arranged close to the end of the first guide rail 23, and the other end of the mounting member 42 extends perpendicularly to the sliding-out direction, and the other end is provided with the elastic rod 41. When the storage cavity 311 is in the closed state, the second face 313 compresses the elastic rod 41 to generate a pre-tightening force. The mounting member 42 is provided in two, and one elastic rod 41 is mounted on each mounting member 42. The two elastic rods 41 respectively exert pre-tightening forces on the two sides of the shell 31, which can prevent the shell 31 from being eccentrically stressed and being deflected. The one end of the mounting member 42 is arranged close to the end of the first guide rail 23, and the other end extends perpendicularly to the sliding-out direction of the shell 31, so that the mounting member 42 can share the mounting side plate of the lower part of the bearing panel 21 with the first guide rail 23, and no additional components are needed to fix the mounting member 42, which can reduce the number of components of the load-bearing assembly 20.
[0037] When the shell 31 is pushed into the lower part of the bearing panel 21, if the pushing force is too large, the second face 313 of the shell 31 may collide with other components of the lower part of the bearing panel 21, and even cause damage to the shell 31 or other components. In an embodiment, as Figures 5-7 shown in the figure, the pre-tightening assembly 40 includes a limiting member 43 and a buffer member 44. The limiting member 43 is connected with the mounting member 42, and the limiting member 43 is used to limit the sliding stroke of the shell 31 in the sliding-in direction, so as to prevent the second face 313 of the shell 31 from colliding with other components of the lower part of the bearing panel 21. The limiting member 43 can be integrally formed on the mounting member 42, that is, the limiting member 43 can be a part of the mounting member 42; or the limiting member 43 can be assembled with the mounting member 42, that is, the limiting member 43 and the mounting member 42 are relatively independent, and the two are respectively processed and then assembled. The buffer member 44 is arranged at the end of the limiting member 43 close to the second face 313. The material of the buffer member 44 can be silica gel or rubber. The buffer member 44 can be deformed under the impact force, which can not only reduce the impact force of the shell 31 on other components of the lower part of the bearing panel 21, but also reduce the impact noise, which is beneficial to improve the user experience.
[0038] Referring to Figure 7 In an embodiment, the elastic rod 41 comprises a support portion 411, a telescopic portion 412 and a first spring 413. The support portion 411 is used to provide support for the telescopic portion 412 and the first spring 413. The support portion 411 is mounted on the bearing panel 21 or the shell 31, the first spring 413 is contained in the support portion 411, and the telescopic portion 412 is in sliding connection with the support portion 411. Under external action, the telescopic portion 412 can slide relative to the support portion 411, the telescopic portion 412 compresses the first spring 413, so that the first spring 413 is elastically deformed. When the storage cavity 311 is in the closed state, one end of the telescopic portion 412 is in contact with the bearing panel 21 or the shell 31, and the other end is in contact with the first spring 413. The telescopic portion 412 compresses the first spring 413 to generate a pre-tightening force, thereby limiting the shell 31 from sliding towards the sliding-in direction.
[0039] In an embodiment, as shown in Figure 8 The pre-tightening assembly 40 comprises an elastic pad 45. The material of the elastic pad 45 can be an elastic material such as silica gel or rubber. Under external action, the elastic pad 45 can be elastically deformed. The elastic pad 45 is in the shape of a block, a sheet or a strip, and the elastic pad 45 is mounted on the lower part of the bearing panel 21 or the second surface 313. For example, the lower part of the bearing panel 21 near the second surface 313 is provided with a baffle, and the elastic pad 45 can be mounted on the baffle; or for example, the elastic pad 45 is mounted on both sides of the bearing panel 21 through the mounting member 42. When the storage cavity 311 is in the closed state, the bearing panel 21 or the second surface 313 compresses the elastic pad 45 to generate a pre-tightening force, thereby limiting the shell 31 from sliding towards the sliding-in direction. The elastic pad 45 can be one or multiple. When the elastic pad 45 is multiple, the multiple elastic pads 45 can be distributed at intervals on the lower part of the bearing panel 21 or the second surface 313, so that the pre-tightening force generated by the multiple elastic pads 45 can act uniformly on the shell 31.
[0040] Referring to Figure 9 In an embodiment, the pre-tightening assembly 40 comprises a first magnetic member 46 and a second magnetic member 47, the first magnetic member 46 is mounted on the lower part of the bearing panel 21, and the second magnetic member 47 is mounted on the second surface 313. For example, the lower part of the bearing panel 21 near the second surface 313 is provided with a baffle, and the first magnetic member 46 can be mounted on the baffle; or for example, the first magnetic member 46 can also be mounted on both sides of the bearing panel 21 through the mounting member 42. The magnetic member can be a permanent magnet or a non-permanent magnet, for example, an electromagnet. When the storage cavity 311 is in the closed state, the first magnetic member 46 and the second magnetic member 47 repel each other to generate a pre-tightening force, thereby limiting the shell 31 from sliding towards the sliding-in direction.
[0041] The locking member 32 can be a pin, and the locking fitting part 22 can be a blind hole structure formed in the lower part of the bearing panel 21. The position of the pin on the shell 31 can be adjusted during assembly, so that the bearing panel 21 can be aligned with the shell 31 when the storage cavity 311 is in the closed state. When the storage cavity 311 is in the closed state, the pin is inserted into the blind hole, and the locking member 32 cooperates with the locking fitting part 22 to limit the sliding of the shell 31 towards the sliding-in direction and the sliding of the shell 31 towards the sliding-out direction, that is, the cooperation of the locking member 32 and the locking fitting part 22 can limit the relative sliding of the shell 31 and the bearing panel 21. However, due to the machining precision, and for the convenience of cooperation between the locking member 32 and the locking fitting part 22, the diameter of the blind hole is usually larger than the outer diameter of the pin, that is, there is a gap between the outer wall of the pin and the inner wall of the blind hole. If the cooperation between the locking member 32 and the locking fitting part 22 limits the sliding of the shell 31 towards the sliding-out direction, and the bearing panel 21 is aligned with the shell 31 when the storage cavity 311 is in the closed state, then when the cooperation between the locking member 32 and the locking fitting part 22 limits the sliding of the shell 31 towards the sliding-in direction, there will be a gap between the bearing panel 21 and the shell 31. In this application, the pre-tightening force provided by the pre-tightening assembly 40 limits the sliding of the shell 31 towards the sliding-in direction, so that the sliding limit of the shell 31 towards the sliding-in direction is not dependent on the locking member 32 and the locking fitting part 22, thereby maintaining a small gap between the bearing panel 21 and the shell 31, and reducing the influence of the gap on the appearance of the trolley.
[0042] In an embodiment, the locking fitting part 22 is assembled with the bearing panel 21, and the position of the locking fitting part 22 on the bearing panel 21 can be adjusted during assembly. For example, Figure 10As shown, the locking member 22 comprises a locking block 221 and a fixing member 222 for fixing the locking member 22. The fixing member 222 can be a screw or a rivet. The locking block 221 is provided with an adjusting hole 223, and the fixing member 222 passes through the adjusting hole 223 to fix the locking block 221 to the lower part of the bearing panel 21. The locking block 221 is arranged on the side close to the first face 312 of the shell 31, so that the locking block 221 is located on the side close to the user in use, and the user can conveniently open or close the storage cavity 311. The size of the adjusting hole 223 in the sliding-out direction is greater than the size in the direction perpendicular to the sliding-out direction. That is, the adjusting hole 223 is substantially in the shape of a racetrack, and the length direction of the adjusting hole 223 is arranged along the sliding-out direction of the shell 31. Before the fixing member 222 completely fixes the locking block 221 to the bearing panel 21 during the assembly of the medical trolley 100, the size of the adjusting hole 223 in the sliding-out direction of the shell 31 is greater than the size in the direction perpendicular to the sliding-out direction, so that there is a gap between the hole wall of the adjusting hole 223 and the outer wall of the fixing member 222 in the sliding-out direction of the shell 31, and the relative position of the locking block 221 and the bearing panel 21 can be adjusted along the sliding-out direction of the shell 31, so that the bearing panel 21 is aligned with the shell 31 when the storage cavity 311 is in the closed state, thereby reducing the difference between the bearing panel 21 and the shell 31. In addition, during the use of the medical trolley 100, if there is a large difference between the bearing panel 21 and the shell 31, the fixing member 222 can be loosened at this time, the position of the locking block 221 on the bearing panel 21 is adjusted, so that the bearing panel 21 is aligned with the shell 31 when the storage cavity 311 is in the closed state, and the difference between the bearing panel 21 and the shell 31 can also be reduced.
[0043] Please refer to Figure 10 、 Figure 11 In an embodiment, the locking block 221 is provided with a locking groove 224, and the locking member 32 comprises a lock 321, which is in sliding connection with the shell 31, so that the lock 321 and the shell 31 can slide relative to each other, and the lock 321 can be inserted into or pulled out of the locking groove 224, thereby locking or unlocking the shell 31. The lock 321 can be arranged in the horizontal direction, so that the lock 321 can be inserted into the locking groove 224 under the action of gravity in the normal state, and the shell 31 remains in the locked state. Alternatively, the locking member 32 further comprises a second spring 322, which is mounted on the shell 31, and the lock 321 can be inserted into the locking groove 224 by means of the second spring 322 in the normal state. Specifically, when the storage cavity 311 is in the closed state, one end of the lock 321 is inserted into the locking groove 224, and the other end of the lock 321 is in contact with the second spring 322, so that the lock 321 can compress the second spring 322, the second spring 322 is elastically deformed, and the second spring 322 exerts a force on the lock 321, thereby inserting the lock 321 into the locking groove 224.
[0044] The latch 321 and the second spring 322 can be directly mounted on the housing 31. Or, as... Figure 11 As shown, in one embodiment, the locking member 32 includes a fixing seat 323, a latch 321, and a second spring 322 mounted on the housing 31 via the fixing seat 323. The fixing seat 323 is mounted on the side where the first surface 312 of the housing 31 is located, and a first receiving groove 325 is formed on the fixing seat 323, within which the second spring 322 and the latch 321 are received. By setting the fixing seat 323 to receive the second spring 322 and the latch 321, the multiple components of the locking member 32 form a relatively independent module, which facilitates the assembly of the locking member 32. The latch 321 can move horizontally to lock the housing 31. For example, the latch 321 is located on one side of the first surface 312 of the housing 31 in the horizontal direction. The latch 321 may also have a protrusion, which the user pushes or pulls to move the latch 321 to lock the housing 31. Or, as... Figure 11 As shown, in one embodiment, the locking member 32 includes a handle 324, which drives the latch 321 to move to lock or unlock the housing 31. The handle 324 is rotatably connected to the fixed base 323. The latch 321 has a second receiving groove 326. One end of the handle 324 is accommodated in the second receiving groove 326, and the other end of the handle 324 is used to apply an external force. When the handle 324 rotates under the external force, it can drive the latch 321 to move away from the locking groove 224 in the height direction, thereby releasing the restriction on the sliding of the housing 31. Setting the latch 321 to move in the height direction allows the latch 321 to be located in the middle area of the first surface 312 of the housing 31 in the horizontal direction. Compared with the latch 321 being located on one side of the housing 31, it can prevent the housing 31 from being eccentrically stressed under the action of pre-tightening force, which is beneficial to reduce the large gap between the two sides of the housing 31 and the bearing panel 21, and can reduce the impact of the gap on the appearance of the trolley. The handle 324 is designed to rotate to move the latch 321. The handle 324 forms a lever that can change the direction of force, thereby facilitating the unlocking operation of the housing 31. Specifically, the force applied by the user to the handle 324 can be along the sliding direction of the housing 31. The handle 324 changes the direction of the force to the height direction and acts on the latch 321, thereby causing the latch 321 to move in the height direction.
