Technical Field
[0001] This instruction manual relates to the medical field, and in particular to a medical trolley. Background Technology
[0002] In hospitals, medical trolleys are used to transport medical equipment and medications. When using a medical trolley, it must be secured in place after reaching its destination to prevent accidents caused by people accidentally bumping into it.
[0003] Currently, the main method for securing medical carts to their destination is to install wheel locks on each wheel of the cart. After confirming that the cart has reached its destination, the doctor controls the wheel locks on each wheel to restrict the movement of each wheel, thus securing the cart to its destination.
[0004] While this method can secure the medical cart to its destination, it requires controlling the wheel locks at each wheel to fix the cart in place, which is time-consuming and inefficient.
[0005] Therefore, how to quickly secure the medical trolley to its destination is an urgent problem to be solved. Summary of the Invention
[0006] This specification provides a medical trolley to partially solve the aforementioned problems existing in the prior art.

[0010] When the pedal (110) is subjected to downward pressure, the driven rod (112) is driven to extend outward in the horizontal direction by the driving rod (111), so that the brake rod (113) moves away from the driving rod in the horizontal direction;
[0011] When the brake lever (113) moves away from the drive lever in the horizontal direction, the brake pin (114) at the end of the brake lever (113) is inserted into the brake hole disc (115) to achieve braking of the medical trolley.
[0012] Optionally, the braking device further includes: a locking plate (120), a spring (130), and a connecting rod (140), wherein the locking plate (120) is provided with a guide groove (150), and a ball head at one end of the connecting rod (140) is embedded in the guide groove (150);
[0013] The spring is used to control the movement of the ball head at one end of the connecting rod (140) in the guide groove (150).
[0014] Optionally, the braking device (100) further includes: a spring upper hanger (160), a spring lower hanger (170), and a connecting plate (180).
[0015] The upper spring post (160) is mounted on the locking plate (120), the lower spring post (170) is mounted on the driving rod (111), one end of the connecting plate (180) is connected to the lower spring post (170), and the other end of the connecting plate (180) is connected to the other end of the connecting rod (140).
[0016] When the distance between the upper spring post (160) and the lower spring post (170) is adjusted by the deformation of the spring, the connecting plate (180) drives the ball head of the connecting rod (140) to move in the guide groove (150).
[0017] Optionally, the locking plate (120) includes a limiting point (121). The limiting point (121) has an inclined surface and a cross section, wherein the inclined surface is used to allow the ball head of the connecting rod (140) to move along the inclined surface to pass through the limiting point (121), and the cross section is used to prevent the ball head of the connecting rod (140) from moving in a direction pointing towards the limiting point (121).
[0018] Optionally, the pattern enclosed by the guide groove (150) is an inverted heart shape.
[0019] Optionally, the braking device further includes a pin (190) for hinged connection between the driven rod (112) and the brake rod (113).
[0020] Optionally, the medical trolley further includes: a workbench (200), a connecting device (210), and a trolley chassis (220).
[0021] Optionally, the connecting device (210) includes a lifting column (240) to control the height of the worktable (200) by adjusting the lifting column (240).

[0025] The medical trolley provided in this specification includes a braking device, which comprises a pedal (110), an active lever (111), a driven lever (112), a brake lever (113), a brake pin (114), and a brake disc (115). In practical applications, when the pedal (110) is subjected to downward pressure, the active lever (111) drives the driven lever (112) to extend outward in the horizontal direction, so that the brake lever (113) moves away from the active lever in the horizontal direction. When the brake lever (113) moves away from the active lever in the horizontal direction, the brake pin (114) at the end of the brake lever (113) is inserted into the brake disc (115) to achieve braking of the medical trolley.
[0026] As can be seen from the medical trolley provided in this specification, when the pedal (110) is subjected to downward pressure, the medical trolley can be braked without having to control the wheel locks at each wheel, thereby improving the braking efficiency of the medical trolley.

[0034] To make the objectives, technical solutions, and advantages of this specification clearer, the technical solutions of this specification will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Exemplary embodiments will be described in detail here, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. Obviously, the described embodiments are only a part of the embodiments of this specification, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without creative effort are within the scope of protection of this specification.
[0035] The following is in conjunction with the appendix Figures 1-6 This specification provides a detailed description of the technical solutions provided in each embodiment.
[0036] In medical settings, doctors need to use medical trolleys to transport medical supplies (such as surgical instruments and medicines). During use, once the medical trolley reaches its destination, it is often necessary to secure it there to prevent accidents caused by people accidentally bumping into it.
[0037] Currently, the conventional method for securing medical trolleys is to operate the wheel locks located on each wheel of the trolley to secure it at the destination after the trolley arrives at its destination.
[0038] While this method can secure the medical cart to its destination, it is time-consuming and inefficient because each time it needs to be secured, the wheel locks on each wheel of the cart need to be operated.
[0039] In order to solve the problem of low efficiency in fixing the medical cart to the destination mentioned above, this manual provides a medical cart.
[0040] In a medical trolley provided in this specification, the medical trolley includes a braking device, wherein the specific structure of the braking device can be as follows: Figure 1 The diagram shows a braking device for a medical trolley provided in this specification.
[0041] exist Figure 1 The braking device includes: a pedal (110), a driving lever (111), a driven lever (112), a brake lever (113), a brake pin (114), and a brake disc (115).
[0042] In practical applications, when the pedal (110) is subjected to downward pressure (e.g., when the pedal (110) is pressed with a foot), the active rod (111) connected to the pedal (110) will move downward due to the downward pressure. As a result, the active rod (111) will drive the driven rod (112) to extend horizontally, so that the brake rod (113) moves away from the active rod (111) in the horizontal direction. It should be noted that the connection between the active rod (111) and the driven rod (112) can be hinged.
[0043] When the brake lever (113) moves away from the drive lever (111) in the horizontal direction, the brake pin (114) at the end of the brake lever (113) is inserted into the brake hole disc (115) to achieve braking of the medical trolley.
[0044] The following is combined Figure 2 This instruction manual provides a schematic diagram illustrating a braking device for a medical trolley.
[0045] like Figure 2 As shown, in a medical trolley provided in this specification, the braking device may further include: a locking plate (120), a spring (130), and a connecting rod (140). The locking plate (120) has a guide groove (150), and the connecting rod (140) may have at least one end that is a ball that can rotate within a certain angle, serving as the ball head of the connecting rod (140). It should be noted that the ball head of the connecting rod (140) can be embedded in the guide groove (150). The spring (130) can be used to control the movement of the ball head of the connecting rod (140) within the guide groove (150). Specifically, when the pedal is subjected to downward pressure, it drives the active rod to move downward. Since the lower spring post is mounted on the active rod, the lower spring post also moves downward with the active rod, thereby increasing the distance between the upper spring post and the lower spring post to stretch the spring and cause it to deform.
[0046] like Figure 2 As shown, the braking device may further include: an upper spring hanger (160), a lower spring hanger (170), and a connecting plate (180). The upper spring hanger (160) is mounted on the locking plate (120), the lower spring hanger (170) is mounted on the drive rod (111), one end of the connecting plate (180) is connected to the lower spring hanger (170), and the other end of the connecting plate (180) is connected to the other end of the connecting rod (140). In actual use, when the distance between the upper spring hanger (160) and the lower spring hanger (170) is adjusted by the deformation of the spring (130), the connecting plate (180) drives the ball head of the connecting rod (140) to move in the guide groove (150).
[0047] The following is combined Figure 3 This specification provides a schematic diagram of a locking plate.
[0048] like Figure 3 As shown, the locking plate (120) may include a limiting point (121), wherein the limiting point has an inclined surface and a cross section. The inclined surface is used to allow the ball head of the connecting rod (140) to move along the inclined surface to pass through the limiting point (121), and the cross section is used to prevent the ball head of the connecting rod (140) from moving in the direction pointing towards the limiting point (121). That is, when the ball head of the connecting rod (140) moves to the inclined surface of the limiting point, it can pass through the limiting point along the inclined surface. When the ball head of the connecting rod (140) moves to the cross section of the limiting point, it will be blocked by the cross section of the limiting point and cannot pass through the limiting point.
[0049] In actual use, when the pedal (110) is not under force, the ball head of the connecting rod (140) is located at... Figure 3 The position of (1). When the pedal (110) is subjected to downward pressure, according to the above connection relationship, the ball head of the connecting rod (140) will move downward along the guide groove (150).
[0050] When the ball head of the connecting rod (140) moves to Figure 3 When in position (2), since the right side of position (2) is the section of the limiting point, the ball head of the connecting rod (140) cannot move into the right guide groove. Therefore, the ball head of the connecting rod (140) will move downward along the left guide groove.
[0051] When the ball head of the connecting rod (140) moves to Figure 3 At position (3), since the limiting point at position (3) is an inclined plane, the ball head of the connecting rod (140) can pass through the limiting point along the inclined plane of the limiting point and reach the... Figure 3 Position (4) in the middle. It should be noted that at this time, the pedal (110) has reached the bottom (the brake pin (114) has been inserted into the brake disc (115) to achieve the braking of the medical cart). The user of the medical cart can release the pedal (110) at this time. Due to the tension generated by the deformation of the spring (130), the ball head of the connecting rod (140) moves upward. Since the left side of position (4) is the section of the limit stop, the ball head of the connecting rod (140) cannot move to the guide groove on the left side of position (4) and can only move to the guide groove on the right side of position (4).
[0052] When the ball head of the connecting rod (140) moves to position (5), because the limiting point at that position is an inclined plane, the ball head of the connecting rod (140) can pass through the limiting point along the inclined plane of the limiting point and reach... Figure 3At position (6), because it only receives the tension of the spring (130) deformation, the ball head of the connecting rod (140) will stop at position (6). At the same time, the ball head moves from position (4) to position (6), and the driving rod moves upward a certain distance, which will drive the driven rod and the brake pin (114) to be pulled out of the brake hole disc (115) by a certain length. However, the brake pin (114) is still in the brake hole disc (115) and plays a braking role.
[0053] When the pedal (110) is subjected to downward pressure, the ball head of the connecting rod (140) will move downward. Since the limiting point on the left side of position (6) is a cross section, the ball head of the connecting rod (140) cannot move to the left guide groove, but can only move to the right guide groove.
[0054] When the ball head of the connecting rod (140) moves to Figure 3 At position (7), because the limiting point at position (7) is an inclined plane, the ball head of the connecting rod (140) can pass through the inclined plane of the limiting point and reach the limiting point. Figure 3 Position (8) in the middle. At this time, the pedal (110) reaches the bottom. When the pedal is released and the pedal is not subjected to downward pressure, the ball head of the connecting rod (140) will move upward due to the pull caused by the deformation of the spring (130). Since the limiting point on the left side of position (8) is a cross section, the ball head of the connecting rod (140) cannot pass through the limiting point and can only move to the guide groove on the right.
[0055] When the ball head of the connecting rod (140) moves to Figure 3 When in position (9), the limiting point at position (9) is an inclined plane, so the ball head of the connecting rod (140) can pass through the limiting point along the inclined plane of the limiting point and return to position (1). At this time, the medical trolley stops braking and resumes its mobility.
[0056] It should be noted that the directional terms such as "up," "down," "left," and "right" mentioned above are based on the observer's direct line of sight. Figure 3 The direction of time. As the observer observes... Figure 3 Depending on the location, the directional words mentioned above, such as "up," "down," "left," and "right," will also change accordingly.
[0057] Based on the function of the limiting plate described above in actual application, it can be seen that in the medical trolley provided in this manual, when in actual use, the user of the medical trolley can brake the medical trolley when pressing the pedal (110) for the first time, and the user of the medical trolley can stop braking the medical trolley when pressing the pedal (110) for the second time, so that the medical trolley can regain its ability to move.
[0058] It should be noted that, from Figure 3 As can be seen, the shape enclosed by the guide groove (150) can be considered as an inverted heart shape. In practical applications, the shape enclosed by the guide groove (150) can be of many kinds, such as... Figure 4 The diagram shows the shape of a guide groove provided in this specification. Examples will not be provided here.
[0059] like Figure 1 As shown, the braking device may further include a pin (190), which is used to realize the hinge connection between the driven rod (112) and the brake rod (113).
[0060] The following is combined Figure 5 This instruction manual provides a schematic diagram of a medical trolley.
[0061] like Figure 5 As shown, the medical trolley may also include: a worktable (200), a connecting device (210), and a trolley chassis (220).

[0062] like Figure 5 As shown, the medical trolley may also include: casters (221) and brake wheels (222). It should be noted that the brake disc (115) is located in the brake wheel (222).
[0063] The following is combined Figure 1 This document explains the connection relationships of the medical trolleys provided.
[0064] like Figure 1 As shown, Figure 1 Each connecting block (211) is used to connect the braking device and the trolley chassis (220). The connection method can be to weld the connecting block (211) to the trolley chassis (220) or to nest the connecting block (211) into the trolley chassis (220). This specification does not specify the connection method.
[0065] It should be noted that, as Figure 6 This is a schematic diagram of a medical trolley provided in this specification. The trolley chassis (220) also includes a housing (230). In practical applications, the connecting block a in the braking device is connected to the housing (230).
[0066] As can be seen from the medical trolley provided in this specification, the medical trolley can be braked when the pedal (110) is subjected to downward pressure, without the need to control the wheel locks at each wheel to brake the medical trolley, thereby improving the braking efficiency of the medical trolley.
[0067] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
