Description

Technical Field

[0001] The utility model relates to the field of monitors, in particular to an unlocking mechanism for a medical multi-parameter monitor. Background Art

[0002] Medical multi-parameter monitors are essential clinical devices that are used to monitor and record patients' vital signs to obtain a variety of indicator data, thereby discovering possible health problems of patients and improving the efficiency and safety of medical work.

[0003] In the medical multi-parameter monitor, the medical multi-parameter monitor can be used independently or in conjunction with a trolley. In order to consider the switching use of the monitor in the two scenarios, the invention patent with application publication number CN114183631A proposes a monitor connection seat and a monitor mounting frame for switching monitors. In the patent, a hook set on the connection seat is engaged with a slot at the bottom of the monitor to lock the monitor, and the monitor can be used in conjunction with the mounting frame; at the same time, an unlocking mechanism is also set on the connection seat, and the unlocking mechanism is used to drive the hook out of the slot, and the monitor can be removed from the mounting frame for independent use.

[0004] The unlocking mechanism of this patent adopts a single-button unlocking method, which is easy to operate but has the risk of accidental touch.

[0005] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a topic to be studied and solved in the present invention. Utility Model Content

[0006] The utility model aims to provide a safer and more stable unlocking mechanism for a medical multi-parameter monitor.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] An unlocking mechanism for a medical multi-parameter monitor, the unlocking mechanism comprising a shell, wherein at least one hook is rotatably connected to the shell via a rotating shaft;

[0009] The hook head penetrates the reserved hole on the surface of the housing and the bayonet on the monitor connection base, and is buckled with the card slot on the monitor through the hook claw;

[0010] The hook tail is provided with a hook spring, which is arranged on the same side as the hook claw and applies a tangential force to the hook tail to rotate the hook and drive the hook claw to engage with the slot;

[0011] The tail of the hook is also provided with a transmission part, which is driven by the pressing keys on both sides of the shell to apply a reverse tangential force to the tail of the hook, so that the hook rotates in the reverse direction and drives the hook claw to leave the slot.

[0012] In a further solution, the transmission parts are provided in two numbers;

[0013] When the hook is provided as one, the two transmission parts act together on the tail of the hook;

[0014] When the number of the hooks is two, the two transmission parts act on the tail of the hooks respectively.

[0015] In a further solution, when the hook is set as one, the two side surfaces of its tail are sloped surfaces, and the relative surfaces of the two transmission parts correspond to the two sloped surfaces respectively. Under the drive of the two pressing keys, the relative surfaces of the two transmission parts gradually approach each other, applying the reverse tangential force to the sloped surfaces.

[0016] In a further solution, when the number of the hooks is two, the opposite surfaces of the two transmission parts respectively abut against the side walls of the two hooks facing away from the hook spring.

[0017] In a further solution, the transmission part includes a pressing rod connected to the inner wall of the pressing key, one end of the pressing rod is externally sleeved with a return spring, and the other end passes through the shell and corresponds to the tail end of the hook.

[0018] In a further solution, at least one pair of positioning rods is provided on the inner wall of the push button, and the positioning rods penetrate the outer shell and are buckled with the inner wall of the outer shell through limiting hooks.

[0019] In a further solution, the upper surface of the shell is detachably connected to the monitor connecting base by screws.

[0020] The working principle and advantages of this utility model are as follows:

[0021] The utility model utilizes two pressing keys to perform double-sided pressing operation to drive all the hooks to detach from the card slots at the bottom of the monitor, and utilizes the card hook spring to drive the card hook to engage with the card slot. The entire unlocking mechanism is convenient for users to quickly disassemble and assemble the monitor. The double-sided pressing operation is ergonomic, the stability of the entire mechanism is better, and it is convenient to use the monitor alone or in conjunction with the monitor mounting frame.

[0022] When there are two hooks, the two push buttons drive the two hooks respectively, and the two hooks are each equipped with a hook spring, so that the entire unlocking mechanism operates more stably and reliably when unlocking, and the structure is simple.

[0023] When there is only one hook, the slope surface at its tail cooperates with the inclined inner end surface of the pressing rod. When the pressing key presses the pressing rod, the slope surface can be driven to rotate, that is, the hook rotates, so as to realize the disengagement of the hook and the slot. The entire unlocking mechanism has a simple structure and is labor-saving and stable to operate. BRIEF DESCRIPTION OF THE DRAWINGS

Example

[0056] See attached Figure 1-9 , an unlocking mechanism for a medical multi-parameter monitor, the unlocking mechanism is arranged below a monitor connection base 100, a monitor 200 is mounted on the monitor connection base 100, and a card slot 210 is arranged at the bottom thereof.

[0057] The unlocking mechanism comprises a housing 1 , in which a hook 2 is rotatably connected via a rotating shaft 3 .

[0058] The head of the hook 2 passes through the reserved hole 13 on the surface of the housing 1 and the socket 110 on the monitor connection base 100 , and is buckled with the slot 210 on the monitor 200 through the hook claw 21 .

[0059] The housing 1 includes a bottom shell 11a and a front shell 11b. When the card slot 210 is set at the bottom of the monitor 200, the bottom shell 11a and the front shell 11b are arranged left and right, the reserved hole 13 is set on the upper surface of the front shell 11b, the hook 2 is vertically set in the front shell 11b, and the rotating shaft 3 is positioned in the bottom shell 11a.

[0060] Among them, each hook 2 can be provided with at least one hook claw 21 at the head. When there are multiple hook claws 21, there are multiple corresponding card slots 210. At this time, the arrangement direction of multiple hook claws 21 is the same, and multiple hook claws 21 are correspondingly engaged with multiple card slots 210 (not shown in the figure).

[0061] At least one hook spring 4 is provided at the tail of the hook 2, and the hook spring 4 is positioned in the bottom shell 11a. The hook spring 4 is provided on the same side as the hook claw 21, and applies a tangential force to the tail of the hook 2, so that the hook 2 rotates and drives the hook claw 21 to engage with the slot 210; Figure 1-2 As shown, when the hook claw 21 is set toward the left, the hook spring 4 is set toward the left; when the upper surface of the housing 1 is matched with the lower surface of the connecting seat, the hook claw 21 is subjected to downward pressure, the hook 2 rotates around the rotating shaft 3, the hook claw 21 tilts to the right, the tail of the hook 2 tilts to the left, and the hook spring 4 is compressed. Figure 1 When the hook 21 enters the slot 210, the upper surface of the housing 1 coincides with the lower surface of the connecting seat, and the hook 21 is not compressed. At this time, the hook spring 4 returns to its natural state and pushes the tail of the hook 2 to the right. Under the limit of the rotating shaft 3, the hook 2 rotates counterclockwise, thereby realizing the rotation and movement of the hook 21 to the left, and tightly engaging with the slot 210. Figure 2 .

[0062] The tail of the hook 2 is also provided with two transmission parts 5, which are arranged in the front shell 11b, and the two transmission parts 5 act together on the tail of the hook 2; the two transmission parts 5 are driven by the pressing keys 6 on the front and rear side walls of the front shell 11b respectively, and apply a reverse tangential force to the tail of the hook 2, so that the hook 2 rotates in the reverse direction and drives the hook claw 21 to disengage from the slot 210; in order to realize the reverse tangential force, the two side surfaces of the tail of the hook 2 are slope surfaces 22, and the opposite surfaces of the two transmission parts 5 correspond to the two slope surfaces 22 respectively; Figure 3-7 As shown, when the hook 2 is vertically arranged, its tail can be perpendicular to the head so as to provide space for the operation of the pressing key 6 and the rotation of the tail; at this time, the slope surface 22 gradually expands outward from top to bottom, and the opposite surfaces of the two transmission parts 5 are also, therefore, after pressing the two pressing keys 6, the opposite surfaces of the two transmission parts 5 gradually approach each other, and the slope surface 22 and the opposite surface move relative to each other, converting the parallel force applied by the hands on both sides into a downward force, that is, applying the reverse tangential force to the slope surface 22, at this time, the slope surface 22 will gradually move downward, and under the limit of the rotating shaft 3, gradually rotate clockwise until the hook claw 21 is disengaged from the card slot 210, and the monitor 200 can be removed.

[0063] See attached Figure 5-6 and Figure 8-9 The transmission part 5 includes a pressing rod 51 connected to the inner side wall of the pressing key 6, one end of the pressing rod 51 is sleeved with a reset spring 52, and the other end passes through the shell 1 and corresponds to the tail end of the hook 2; when the two pressing keys 6 are pressed inward, the two pressing rods 51 move inward and approach each other, and their inner end surfaces can cooperate with the ramp surface 22 to realize the rotation of the ramp surface 22, and the hook 21 is disengaged from the slot 210, so that the monitor 200 can be removed. During this process, the reset spring 52 is in a compressed state; when the two pressing keys 6 are released, under the reaction force of the reset spring 52, the pressing key 6 will drive the pressing rod 51 to return to its original position.

[0064] In order to prevent the push key 6 from detaching from the shell 1, at least one pair of positioning rods 7 are provided on the inner wall of the push key 6, and the positioning rods 7 penetrate the shell 1 and are buckled with the inner wall of the shell 1 through the limit hooks 8; when the push key 6 is pressed, the positioning rods 7 can move inward with it, and when the push key 6 is released, the positioning rods 7 move outward with it, and when the push key 6 is reset, the limit hooks 8 are buckled with the inner wall of the shell 1, preventing the push key 6 from continuing to move outward. Example

[0065] This embodiment is basically the same as Embodiment 1, except that:

[0066] See attached Figure 10-14The two hooks 2 are rotatably connected in the housing 1 through the rotating shaft 3, and the two hooks 2 are correspondingly engaged with the two slots 210 on the monitor connecting socket 100. The monitor 200 can be locked and unlocked by only using the two hooks 2 without other assembly parts.

[0067] The shell 1 includes an intermediate shell 12a and two side plates 12b; when the card slot 210 is set at the bottom of the monitor 200, an installation cavity is formed between the left and right sides of the intermediate shell 12a and the two side plates 12b, two hooks 2 and two transmission parts 5 are respectively arranged in the two installation cavities, two push buttons 6 are arranged on the left and right side plates 12b, and two reserved holes 13 are respectively arranged on the top of the two installation cavities.

[0068] The two transmission parts 5 act on the tail of the hook 2 respectively, and the opposite surfaces of the two transmission parts 5 abut against the side walls of the two hooks 2 facing away from the hook spring 4 respectively.

[0069] The hook claws 21 of the two hooks 2 may be arranged in the same direction or in opposite directions.

[0070] When the hook claws 21 of the two hooks 2 are arranged in the same direction, the hook claws 21 of the two hooks 2 face inwards and engage with the inner edges of the two slots 210. The hook spring 4 is arranged on the inner sides of the two hooks 2, and the two transmission parts 5 are arranged on the outer sides of the two hooks 2. Fig.13 .

[0071] When the upper surface of the housing 1 is matched with the lower surface of the connecting seat, the hook claws 21 of the two hooks 2 are subjected to downward pressure, the hook 2 rotates around the rotating shaft 3, the two hook claws 21 are tilted outwards, the tails of the two hooks 2 are tilted inwards, and the hook spring 4 is compressed. Fig.10 When the hook 21 enters the slot 210, the upper surface of the housing 1 coincides with the lower surface of the connecting seat, and the hook 21 is not compressed. At this time, the hook spring 4 returns to its natural state and pushes the tail of the hook 2 outward to restore its original position. The two hooks 21 rotate inward to restore their original positions and are tightly engaged with the slot 210. Fig.11 .

[0072] When the hook claws 21 of the two hooks 2 are arranged in opposite directions, the hook claws 21 of the two hooks 2 face outwards and engage with the outer edges of the two slots 210, the hook springs 4 are arranged on the outside of the two hooks 2, and the two transmission parts 5 are arranged on the inside of the two hooks 2 (not shown in the figure).

[0073] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
