DETAILED DESCRIPTION

[0039] In order to make the purpose, technical scheme and advantages of the utility model more clear, the technical scheme in the utility model will be described clearly and completely below in combination with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0040] As Figures 1 to 6 shown, the embodiment of the utility model discloses a kind of medical trolley, including base 1, tray assembly 2 and limiting assembly 3, tray assembly 2 is detachably connected with base 1, tray assembly 2 includes supporting piece 22 and tray 21, tray 21 is equipped at the top of supporting piece 22, tray 21 is suitable for being connected with medical instrument 7, one of supporting piece 22 and tray 21 is equipped with sliding groove 23 extending along the length direction of supporting piece 22, the opening of sliding groove 23 is towards with the width direction of supporting piece 22 consistent, the other of supporting piece 22 and tray 21 is equipped with sliding block 24 matched with sliding groove 23, limiting assembly 3 is used to limit the relative sliding between supporting piece 22 and tray 21.

[0041] In order to make the technical solutions of the present application easier to be understood, the technical solutions of the present application are further described below taking the length direction of the supporting member 22 consistent with the left-right direction and the width direction of the supporting member 22 consistent with the front-rear direction as an example, wherein the left-right direction and the front-rear direction are as shown in Figure 1 In addition, the up-down direction is as shown in Figure 1

[0042] For example, as shown in Figure 1 The tray 21 is located at the top of the supporting member 22 and is used to carry the medical instrument 7.

[0043] The tray 21 is detachably connected with the medical instrument 7, for example, the tray 21 is connected with the medical instrument 7 through clamping or bolt connection.

[0044] One of the supporting member 22 and the tray 21 is provided with a sliding groove 23 extending along the left-right direction, and the other of the supporting member 22 and the tray 21 is provided with a sliding block 24 matched with the sliding groove 23. For example, the supporting member 22 is provided with the sliding groove 23, and the tray 21 is provided with the sliding block 24, or the supporting member 22 is provided with the sliding block 24, and the tray 21 is provided with the sliding groove 23.

[0045] The opening of the sliding groove 23 faces left or right, that is, the two side walls forming the sliding groove 23 are arranged in the up-down direction, and when the sliding block 24 is inserted into the sliding groove 23, the sliding groove 23 can limit the movement of the sliding block 24 in the up-down direction, so that the sliding block 24 can only move in the left-right direction or the front-rear direction. Then, the position of the sliding block 24 is further limited by the limiting assembly 3, so as to limit the relative movement between the sliding block 24 and the sliding groove 23, and further to make the supporting member 22 and the tray 21 have no relative displacement, so as to fix the medical instrument 7 on the tray assembly 2.

[0046] After the tray 21 is slid into position, the limiting assembly 3 is used to lock the position of the tray 21 to prevent accidental sliding during use, thereby ensuring the safety and stability of the medical instrument 7. The limiting assembly 3 includes a spring pin, a buckle or a screw, etc.

[0047] In the related art, the connection support of the medical trolley is designed to be relatively single, and usually can only be adapted to medical instruments 7 of specific brands or models. This limits the application range of the medical trolley, and users need to equip different trolleys for different brands of equipment, which increases the procurement and management costs. Moreover, when the medical instrument 7 is fixed on the medical trolley through the connection support, the replacement process of the medical instrument 7 is often very cumbersome and has low replacement efficiency.

[0048] ​The design of the groove 23 and slider 24 in this invention makes the installation and disassembly of the tray 21 extremely simple. The doctor only needs to align the slider 24 with the groove 23 and then gently push it in or pull it out to complete the installation or operation. The entire process requires no complex tools or specialized skills, greatly reducing the difficulty of operation, saving time and labor costs, and thus facilitating the installation or disassembly of the medical instrument 7 and the medical trolley.

[0049] To further improve replacement efficiency, this invention equips each medical instrument 7 with an identical tray 21. Normally, the tray 21 is installed on the medical instrument 7. When replacing the medical instrument 7, simply remove the old instrument and tray 21 together, and then install the new instrument and tray 21 onto the support 22. This pre-installed tray 21 design avoids the need to disassemble and reassemble the tray 21 each time the medical instrument 7 is replaced, significantly improving replacement efficiency, reducing operation time, and enabling a single medical cart to be compatible with multiple medical instruments 7, thus improving the versatility of the medical cart.

[0050] Therefore, the medical trolley of this utility model embodiment has the advantages of high efficiency in replacing medical instruments 7 and strong versatility.

[0051] In some embodiments, two slides 23 are provided, and the two slides 23 are arranged at intervals in the width direction of the support member 22. The openings of the two slides 23 are arranged facing each other. Two sliders 24 are provided, and the two sliders 24 are arranged in a one-to-one correspondence with the two slides 23.

[0052] For example, such as Figure 2 and Figure 3 As shown, the support member 22 is provided with two sliding grooves 23, which are arranged at intervals in the front-to-back direction, and the openings of the two sliding grooves 23 face each other, that is, the opening of the front sliding groove 23 faces backward, and the opening of the rear sliding groove 23 faces forward. The tray 21 is provided with two sliders 24, which are correspondingly arranged with the two sliding grooves 23. Alternatively, the support member 22 is provided with two sliders 24, and the tray 21 is provided with two sliding grooves 23.

[0053] Therefore, the two bottom walls of the two slide grooves 23 are arranged at intervals in the front-back direction. When the slider 24 is inserted into the slide groove 23, the two bottom walls can restrict the movement of the slider 24 in the front-back direction. At the same time, the side walls of the slide groove 23 can restrict the movement of the slider 24 in the up-down direction. Thus, it is ensured that the slider 24 can only slide in the left-right direction, which facilitates installation and disassembly.

[0054] Optionally, the support member 22 has a protrusion in the middle for connection with medical equipment, and the front and rear edges of the support member 22 are provided with strip plates, which are set lower than the protrusion. The strip plates are the sliders 24.

[0055] In some embodiments, the medical trolley comprises an adjusting assembly 4, which is arranged between the base 1 and the tray assembly 2, and the tray assembly 2 is rotatably connected to the adjusting assembly 4 along the length direction of the supporting member 22, and the adjusting assembly 4 can adjust the rotation angle of the tray assembly 2.

[0056] The adjusting assembly 4 is arranged at the bottom of the tray assembly 2, and the tray assembly 2 can rotate relative to the adjusting assembly 4 along the left-right direction, so that the adjusting assembly 4 can adjust the tray assembly 2 at multiple angles, greatly improving the flexibility and adaptability of the medical trolley.

[0057] Optionally, the bottom of the supporting member 22 is provided with a rotating shaft, and the adjusting assembly 4 is provided with a corresponding bearing or shaft hole, so that the supporting member 22 can freely rotate on the adjusting assembly 4 through the rotating shaft. Alternatively, the bottom of the supporting member 22 is hinged to the adjusting assembly 4, so that the supporting member 22 can rotate along the left-right direction.

[0058] In some embodiments, the adjusting assembly 4 comprises a connecting rod 41 and an adjusting rod 42, one end of the connecting rod 41 is connected to the base 1, the connecting rod 41 is provided with a first through hole 411, the first through hole 411 penetrates the connecting rod 41 along the length direction of the supporting member 22, the adjusting rod 42 is rotatably arranged in the first through hole 411, the adjusting rod 42 is provided with a first fitting part 421, the bottom of the supporting member 22 is provided with an avoiding part 221 and a second fitting part 222, the other end of the connecting rod 41 can extend into the avoiding part 221 and is spaced apart from the inner wall surface of the avoiding part 221, and the first fitting part 421 is fixedly connected with the second fitting part 222.

[0059] For example, as shown in FIG. 1, the connecting rod 41 extends along the up-down direction, and the lower end of the connecting rod 41 is detachably connected to the base 1, for example, bolted or buckled. Figures 3 to 5 The upper end of the connecting rod 41 can extend into the avoiding part 221, but there is a space between the upper end of the connecting rod 41 and the inner wall surface of the avoiding part 221, which can avoid interference between the connecting rod 41 and the supporting member 22, and can ensure that the first fitting part 421 can smoothly fit with the second fitting part 222.

[0060] The first through hole 411 penetrates the connecting rod 41 along the left-right direction, and the diameter of the adjusting rod 42 is slightly smaller than the diameter of the first through hole 411, so as to ensure that the adjusting rod 42 can smoothly rotate in the through hole. The second fitting part 222 is arranged on one side of the avoiding part 221, and the first fitting part 421 is fixedly connected with the second fitting part 222, for example, bolted, so that the adjusting rod 42 is fixedly connected with the supporting member 22, and thus the supporting member 22 can be rotated when the adjusting rod 42 is rotated.

[0061] The medical trolley of the utility model, utilizes the connecting rod 41, the adjusting rod 42 and the avoiding portion 221 and the second fitting portion 222 of the bottom of the supporting piece 22, realizes the rotation of the tray assembly 2, thereby improving the flexibility of the medical instrument 7.

[0062] In some embodiments, the first fitting portion 421 is two, and the two first fitting portions 421 are respectively arranged at the two ends of the adjusting rod 42; the second fitting portion 222 is two, and the avoiding portion 221 is arranged between the two second fitting portions 222 in the length direction of the supporting piece 22; and the two first fitting portions 421 and the two second fitting portions 222 are one-to-one correspondingly arranged.

[0063] For example, as shown in Figure 3 and Figure 4 , one first fitting portion 421 is arranged at each end of the adjusting rod 42, and the bottom of the supporting piece 22 is provided with two second fitting portions 222; each first fitting portion 421 can be a plane, a protrusion or other shapes, and the specific design depends on the structure of the second fitting portion 222, as long as the two can be closely fitted and cannot rotate relative to each other.

[0064] Optionally, the first fitting portion 421 and the second fitting portion 222 are both planes, thereby facilitating processing. The first fitting portion 421 and the second fitting portion 222 are both provided with bolt holes, and the two are connected through bolts.

[0065] The medical trolley of the utility model embodiment, the design of the two first fitting portions 421 and the two second fitting portions 222 not only provides double fixing points, but also disperses the load and enhances the stability of the overall structure.

[0067] For example, as shown in Figure 4 and Figure 5 , the first threaded hole 44 extends in the front-rear direction, the first threaded hole 44 is in communication with the first through hole 411, and when it is necessary to fix the angle of the tray assembly 2, the locking bolt 43 is only needed to be screwed into the first threaded hole 44 until the locking bolt 43 abuts against the adjusting rod 42.

[0068] Therefore, the locking of the adjusting rod 42 can be realized by tightening the locking bolt 43 to abut against the adjusting rod 42, which not only ensures that the tray assembly 2 can be fixed after being adjusted to the required angle, but also simplifies the operation process, so that the angle adjustment of the medical instrument 7 is more convenient.

[0069] In some embodiments, the tray 21 is provided with a first limiting hole 211, the supporting piece 22 is provided with a second limiting hole 223 corresponding to the first limiting hole 211, and the limiting assembly 3 comprises a limiting piece 31 which can enter and exit the first limiting hole 211 and the second limiting hole 223.

[0070] For example, as shown in Figure 5 and Figure 6 , the tray 21 is provided with a first limiting hole 211, the supporting piece 22 is provided with a second limiting hole 223 corresponding to the first limiting hole 211, and the center line of the first limiting hole 211 and the center line of the second limiting hole 223 completely coincide when the tray 21 and the supporting piece 22 are aligned. The size and shape of the second limiting hole 223 are consistent with those of the first limiting hole 211, so that the limiting piece 31 can pass through the two limiting holes at the same time, realizing the fixed connection of the tray 21 and the supporting piece 22. The medical trolley of the embodiment of the utility model can ensure that the tray 21 is fixed on the supporting piece 22 after being adjusted in place, thereby preventing the tray 21 from sliding accidentally, and further ensuring the stability of the medical instrument 7.

[0075] The connecting rod 32 is movably arranged in the inner cavity 341 in the up-down direction. The limiting piece 31 is fixedly connected with the top end of the connecting rod 32, and the bottom of the connecting rod 32 is fixedly connected with the pulling piece 33. Thus, when the pulling piece 33 is moved, the pulling piece 33 drives the limiting piece 31 to move up and down through the connecting rod 32, so that the limiting piece 31 can enter and exit the first limiting hole 211 and the second limiting hole 223.

[0076] The cross-sectional area of the limiting piece 31 is smaller than the cross-sectional area of the inner cavity 341, so that the limiting piece 31 can enter the inner cavity 341 when it is moved downward, thereby not affecting the relative sliding between the tray 21 and the supporting piece 22.

[0077] The cross-sectional area of the pulling piece 33 is larger than the cross-sectional area of the inner cavity 341, so that the pulling piece 33 cannot enter the inner cavity 341 and affect the use of the limiting assembly 3.
