[0021] The following is a further detailed description of the present invention or the technical solution of the present invention through specific embodiments and in conjunction with the accompanying drawings of the specification;

[0022] In the description of the present invention, it should be understood that the terms "front", "rear", "up", "down", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] In the description of the present utility model, it should be noted that, unless otherwise specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection of two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. Example 1

[0024] See also Figure 1 , Figure 5 and Figure 6 The present embodiment provides a medical trolley, which includes a trolley body 100 and at least one group of arm structures. In the present embodiment, it includes two groups of arm structures 1 and 2 distributed on the left and right. Since the two arm structures are the same, only one of the arm structures is described in detail. Both arm structures are arranged on the trolley body, and the arm structure includes a rotating shaft A13 installed on the trolley body and an arm 11 rotatably connected to the rotating shaft A13. The free end of the arm 11 is provided with at least one bracket 15, and the bracket 15 forms at least one U-shaped groove for hanging medical equipment. In this way, the utility model provides a brand-new arm structure of a medical trolley, which is suitable for hanging medical equipment of various specifications, and can be freely rotated around the rotating shaft A on the trolley body to adjust the angle of the arm at any time, which is convenient for doctors to operate. In addition, the user can fold the rotating arm together with the trolley body to reduce the storage volume of the trolley.

[0025] One end of the support arm 11 provided in this embodiment is rotatably connected to the rotating shaft A 13 of the trolley top shell through a shaft sleeve A 18 to realize the circumferential rotation of the support arm 11 with the rotating shaft A 13 as the axis. The other end of the support arm is provided with a rotating shaft B 16, and the hanging bracket is rotatably connected to the rotating shaft B 16 through a shaft sleeve B 17. In this way, the circumferential rotation of the hanging bracket 15 itself is realized. This arrangement facilitates the operation, transportation and storage of the support arm and the hanging bracket.

[0026] In some embodiments, a plurality of U-shaped grooves are formed on the hanger, and the plurality of U-shaped grooves are respectively suitable for hanging syringes, puncture needles, and retrieval forceps, that is, conventional built-in instruments are all hung on the medical trolley, which has strong adaptability and is more conducive to doctor's operation. Doctors can arbitrarily choose the medical instruments they want to use.

[0027] In some embodiments, the rotating shaft A is installed on the rear side of the top shell of the trolley body, and the support arm extends upward at an angle. Firstly, it ensures the free rotation of the support arm and avoids the problem of limited rotation caused by its horizontal extension; secondly, it avoids the technical problem of excessive height caused by vertical extension, which is not conducive to doctors taking medical equipment; and more importantly, it allows it to be rotated to the top of the trolley body when storing to reduce the storage volume.

[0028] Furthermore, the bottom of the rotating shaft B16 is connected with a bottom cover 161, and the bottom cover and the rotating shaft B are locked by screws to fix the hanger. The connection between the rotating shaft B and the bottom cover is respectively provided with a groove and a protrusion 162 for positioning and matching, so as to prevent the hanger from driving the bottom cover to rotate during circumferential rotation, thereby causing relative displacement between the bottom cover and the rotating shaft B, affecting the loosening of the screws, and preventing the bottom cover from loosening and falling off. During assembly, the bottom cover is fixed in position according to the groove and the rotating shaft B, which is more convenient. Example 2

[0029] See also Figure 1 The support arm structure provided in this embodiment includes a rotating shaft A13, a support arm 11 and a blocking structure 12, wherein the rotating shaft A13 is installed on the trolley body 100; the support arm 11 is rotatably connected to the rotating shaft A13, and at least one hanging bracket 15 is provided at the free end of the support arm 11, and medical instruments such as syringes, puncture needles, and retrieval forceps are hung on the hanging bracket 15.

[0030] The blocking structure 12 is arranged on the trolley body 100, and the blocking structure 12 switches between a blocking state and an unlocking state. When the blocking structure is in the blocking state, it at least blocks the arm 11 from freely moving toward the trolley body, and when the blocking structure 12 is in the unlocking state, it allows the arm to move freely. In this way, during the use of the medical trolley, when the blocking structure 12 is in the blocking state, the arm can be locked away from the trolley body, avoiding the risk of the arm hitting the trolley body, and avoiding the medical equipment on the rack 15 from contaminating or damaging the trolley. By setting the blocking part, a safe distance is constructed between the medical equipment and the trolley body. In addition, when the arm can be locked in a state of being folded together with the trolley body, the storage volume of the arm is reduced, which is convenient for storage and transportation. At the same time, when the blocking structure is in the unlocking state, the arm can rotate freely to reach an ideal position, and it is easy to store.

[0031] In some preferred embodiments, the blocking structure can prevent the support arm from rotating toward the operating side, in which case a safe distance can be formed between the trolley body and the support arm, or prevent the support arm from rotating away from the operating side when the support arm reaches the operating side, so that the support arm and the trolley body are folded together to reduce the storage volume of the trolley.

[0032] In some embodiments of the present invention, please refer to Figure 2-Figure 4 The blocking structure includes a blocking portion 121 telescopically arranged on the trolley body so that the blocking portion 121 can be extended or retracted. The extension of the blocking portion can prevent the support arm from freely rotating toward the trolley body, and the support arm and the trolley body can be folded and locked. The support arm can be freely rotated by retracting the blocking portion. The blocking portion here realizes the blocking function through telescopic activity.

[0033] In some specific embodiments, the blocking structure further includes an elastic member, which often pushes the blocking portion 121 so that the blocking portion 121 is always kept in a blocking state. In this way, the setting of the elastic member ensures that the blocking portion 121 is always kept in an extended position so that the hanger 15 is always kept in a safe position, thereby preventing the medical devices hung on the hanger 15 from contaminating or damaging the trolley. In addition, when the support arm moves to the trolley body, the blocking portion is released. At this time, the blocking portion will be moved upward by the upward resetting force of the elastic member until it supports (it can support on the top or side) the support arm, so that the support arm is relatively fixed. In this way, during the transportation of the trolley, the function of storing the support arm is to facilitate packaging and transportation.

[0034] For the convenience of operation, the blocking structure 12 and the rotating shaft A 13 are arranged on the top of the trolley body. In order to prevent the bracket 15 from moving toward the front side of the trolley body 100, the blocking part 121 is arranged on the front side of the rotating shaft A. In this way, the blocking structure is convenient for preventing the bracket 15 from rotating toward the front side of the bracket 15 with the rotating shaft as the axis. The trolley body 100 has a front side for doctors to operate, that is, the operating side. For example, a display, an operating keyboard, a mouse, and a training model are all arranged on the front side of the trolley body 100. The "front side" here refers to the side facing the user. Here, blocking the support arm from moving forward means that the blocking part here prevents the support arm from rotating toward the operating side of the trolley body.

[0035] Specifically, the trolley body includes a shell, wherein the shell has a top shell 101 located at the top, so that a connecting rod 102 is installed on the top shell to install a display, and an area 103 for installing a keyboard and a mouse is also provided on the top shell. For the convenience of operation, the support arm is also installed on the top shell to facilitate the axial hanging of the medical device. At the same time, in order to minimize interference with the operation on the operating side, the mounting end of the support arm, that is, the rotating shaft A, is installed on the rear side of the top shell. In this way, the blocking part needs to be installed on the front side of the rotating shaft A to prevent the support arm from rotating toward the front side of the trolley body.

[0036] In some embodiments, the blocking structure includes a base 123 and a blocking portion 121, the base 123 is fixedly installed on the inner side of the top shell 101, the blocking portion 121 is telescopically arranged to penetrate the top shell, and the blocking portion 121 and the base 123 are slidably matched in the axial direction, and the spring member is arranged between the blocking portion 121 and the base 123. In this way, when the blocking portion 121 moves downward, the spring member is in a tense state, releasing the locking and blocking state of the support arm 11, and allowing the support arm to swing freely; when the pressure on the blocking portion 121 is released, the spring member provides a reset force to the blocking portion, automatically resetting it to the extended position, that is, the blocking state.

[0037] In some embodiments of this embodiment, the blocking structure further includes a limit assembly for limiting the maximum movement of the blocking portion, so that when the blocking portion moves axially downward, the limit assembly can limit the downward movement of the blocking portion, and when the blocking portion is reset axially upward, the limit assembly can limit the upward movement of the blocking portion to prevent it from falling out of the trolley body. Exemplarily, the blocking portion can form a limit fit with the trolley body, and can also form a limit fit with the base. In some examples, the blocking portion includes an upper cover 1211 and a sliding rod 1212, the upper cover 1211 is arranged to pass through the top shell 101, the sliding rod 1212 is connected to the upper cover 1211, a circumferential limiting step 1213 is formed at the bottom of the upper cover 1211, and the top shell is provided with a stop wall that cooperates with the limiting step 1213 to prevent the upper cover 1211 from falling out; the base includes a seat body 1231 and a sleeve 1232, the sleeve 1232 is connected to the seat body 1231, the seat body 1231 has a stop bottom wall 1233 to limit the maximum downward movement stroke of the upper cover 1211, the sliding rod 1212 is slidably matched with the sleeve 1232, and the spring member is sleeved on the outside of the sliding rod and the sleeve; one end of the spring stops on the upper cover and the other end stops on the seat body.

[0038] This example provides a working method of a support arm structure:

[0039] In the initial state, the support arm is rotated. Due to the protrusion of the upper cover, the upper cover limits the rotation degree of the support arm, so that the support arm cannot continue to rotate toward the side of the trolley body, thereby preventing the support arm from rotating and causing the medical equipment on the rack to hit the trolley body during the use of the medical trolley;

[0040] Position adjustment: Press the upper cover, the slide bar slides axially in the sleeve, the upper cover retreats into the top shell or is on the same horizontal plane with the top shell, the spring is compressed, the support arm is rotated, and the support arm can smoothly rotate to the side of the blocking part to reach the ideal position; release the upper cover, and the upper cover returns to the extended position under the action of the spring;

[0041] Storage state: Loosen the blocking upper cover. At this time, the blocking upper cover will move upward due to the upward return force of the spring. The support arm can be supported from the side or top surface to make the support arm relatively fixed. In this way, during the transportation of the trolley, the function of the storage arm is to facilitate packaging and transportation.
