Description

Technical Field

[0001] This invention relates to the medical field, specifically to a nursing cart management device. Background Technology

[0002] Nursing carts are indispensable nursing aids in hospital wards, outpatient clinics, nurse stations, and other settings. They are mainly used to carry and transport medications, infusion sets, medical consumables, sterilization equipment, and nursing documents. They can help medical staff efficiently complete daily nursing tasks such as bedside dressing changes, infusion therapy, and ward rounds. The standardization of their storage and management directly affects the efficiency of passage through the ward and medical safety.

[0003] Currently, most medical institutions in China lack dedicated designated management devices for unused nursing carts. They are generally placed haphazardly in vacant areas along ward corridors and around nurses' stations. This extensive management approach has many drawbacks: First, randomly parked carts easily obstruct medical passageways, compressing the effective passage space in wards. During emergency transport and peak hours, this can cause congestion, affecting emergency response efficiency and hindering the cleanliness of the ward environment. Second, without fixed restraints, carts are prone to sliding, shifting, or even tipping over after being bumped or scratched by people. This can lead to spillage and damage of medicines and fragile instruments, posing certain medical safety hazards and failing to meet the requirements of refined ward management.

[0004] While some existing technologies have developed cart fixing brackets, they still have significant technical drawbacks. On the one hand, these fixing devices are mostly fixed structures with non-adjustable fixing point heights, only suitable for a single type of nursing cart. However, in clinical settings, nursing carts come in various types, such as treatment carts, infusion carts, medication carts, and nursing carts, each with different frame heights and handle diameters. Fixed devices cannot be universally adapted, limiting their applicability and making it difficult to achieve unified storage and management of various types of carts in the ward. Therefore, a nursing cart management device needs to be designed to improve these issues. Summary of the Invention

[0005] The problem to be solved by the present invention is to provide a nursing cart management device to address the above-mentioned shortcomings of the prior art. The invention aims to solve the problem that the existing nursing cart fixing management devices are mostly fixed structures with non-adjustable fixing point heights, and can only be adapted to a single size of nursing cart.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a nursing trolley management device, including an assembly plate, a groove provided on the front side of the assembly plate, a mounting frame fixedly connected in the groove, a front receiving cavity opened at the front end of the mounting frame, a rear receiving cavity opened at the middle of the rear end of the mounting frame, and a through groove opened between the rear receiving cavity and the front receiving cavity, the width of the through groove being smaller than that of the rear receiving cavity and the front receiving cavity.

[0007] The front receiving cavity is provided with a trolley fixing mechanism, which is used to clamp and fix the transverse push rod of the nursing trolley.

[0008] A height adjustment mechanism is provided between the trolley fixing mechanism and the mounting frame, and the height adjustment mechanism is used to adjust the longitudinal height of the trolley fixing mechanism.

[0009] Preferably, the trolley retaining mechanism includes a movable frame disposed in the front receiving cavity. The movable frame has two clamps symmetrically distributed vertically inside. A vertically arranged guide rod is also fixedly connected inside the movable frame. The clamps are slidably connected to the guide rod. A first elastic element is fixedly connected between the opposite sides of the two clamps and the inner wall of the front receiving cavity.

[0010] Preferably, each of the two clamping plates has a clamping groove on one side opposite to the other, the clamping groove having a V-shaped structure design, and each of the two clamping plates has an outwardly expanding guide plate at the end away from the moving frame.

[0011] Preferably, the height adjustment mechanism includes a positioning block fixedly connected to the back of the movable frame, and a plurality of positioning slots are longitudinally provided on the inner wall of the front receiving cavity corresponding to the positioning block for the positioning block to be aligned and engaged.

[0012] The height adjustment mechanism also includes a tension reset component, which is used to unlock and automatically reset the positioning block when the height of the trolley fixing mechanism is adjusted.

[0013] Preferably, the stretching reset assembly includes a stop plate disposed in the rear receiving cavity and a guide shaft fixedly connected to the back of the movable frame. The back of the stop plate has a receiving groove corresponding to the position of the guide shaft. The inner wall of the receiving groove has a through hole through which the stop plate passes. One end of the guide shaft passes through the through hole and is fixedly connected to a locking ring in the receiving groove. A second elastic element is disposed inside the receiving groove and between the locking ring and the inner wall of the receiving groove. The second elastic element is sleeved on the outside of the guide shaft.

[0014] Preferably, a guide groove is provided on the inner wall of the rear receiving cavity in the vertical direction, and a plurality of guide rollers placed in the guide groove are rotatably connected to the stop plate.

[0015] Preferably, auxiliary pull plates extending to the outside of the mounting frame are fixedly connected to both sides of the movable frame.

[0016] Preferably, a positioning groove is provided at the bottom end of one side of the assembly plate, and a positioning protrusion embedded in the positioning groove is provided at the bottom end of the other side of the assembly plate.

[0017] Preferably, a linkage response component is provided between the height adjustment mechanism and the trolley fixing mechanism. The linkage response component controls the height adjustment mechanism to switch between a locked state and an adjustable state in response to the longitudinal external force on the trolley fixing mechanism.

[0018] The linkage response component includes a force transmission rod fixedly connected to the back of the movable frame, and a response wedge block slidably assembled in the rear receiving cavity. One end of the response wedge block abuts against the force transmission rod, and the other end of the response wedge block slides against the stop plate of the height adjustment mechanism through an inclined wedge surface.

[0019] When the trolley retaining mechanism is subjected to downward longitudinal pressure, the force transmission rod pushes the response wedge block to slide downward. The response wedge block forces the stop plate to move away from the inner wall of the rear receiving cavity through the inclined wedge surface, so that the positioning block disengages from the positioning slot to allow height adjustment. When the longitudinal pressure is removed, the response wedge block returns to its original position under the action of the elastic reset member, and the stop plate resets synchronously, so that the positioning block re-engages into the corresponding positioning slot to achieve automatic locking.

[0020] Preferably, the linkage response component further includes an anti-disengagement locking device, which is disposed in the through groove between the front receiving cavity and the rear receiving cavity. The anti-disengagement locking device includes a backstop ring fixedly fitted on the outside of the force transmission rod, and a backstop pawl rotatably connected to the inner wall of the through groove. A reset torsion spring is connected between the backstop pawl and the inner wall of the through groove.

[0021] The anti-reverse claw always tends to deflect toward the anti-reverse ring under the action of the reset torsion spring. The outer peripheral wall of the anti-reverse ring is provided with a number of one-way anti-reverse grooves at axial intervals. The one-way anti-reverse grooves engage with the anti-reverse claw in one direction, which is used to restrict the trolley fixing mechanism to move only in one direction after the positioning block is disengaged from the positioning groove, and to prevent the trolley fixing mechanism from accidentally slipping due to misoperation.

[0022] Preferably, the clamping plate of the trolley fixing mechanism is further provided with an adaptive clamping triggering component. The adaptive clamping triggering component includes a touch pressure plate embedded in the bottom of the clamping groove and a triggering link disposed in the moving frame. A push column is fixedly connected to the back of the touch pressure plate. The push column passes through the clamping plate and movably abuts against one end of the triggering link.

[0023] The other end of the trigger link extends to the outside of the moving frame and is fixedly connected to a positioning indicator block. When the transverse push rod of the nursing trolley is fully inserted into the clamping groove and presses the touch plate, the touch plate drives the trigger link to slide through the push column, so that the positioning indicator block extends out of the outer wall of the moving frame to indicate the clamping position.

[0024] Preferably, a wall-mounted base is provided on the rear side of the assembly plate, and a deflection adjustment assembly is provided between the wall-mounted base and the assembly plate. The deflection adjustment assembly includes an arc-shaped adjustment rail fixed to the wall-mounted base and a guide slider fixed to the back of the assembly plate and slidably fitted into the arc-shaped adjustment rail. The arc-shaped adjustment rail has multiple angle positioning holes along the arc direction, and the guide slider is provided with positioning pins that selectively engage with the angle positioning holes. The deflection adjustment assembly is used to adjust the deflection angle of the assembly plate relative to the wall-mounted base so that the trolley fixing mechanism can be fixed at different orientation angles in the horizontal plane, adapting to the management needs of the nursing trolley parking angle for ward passages with different orientations.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. The trolley fixing mechanism of the present invention can quickly snap into and fix the nursing trolley frame by cooperating with the upper and lower clamps and the first elastic element. The operation is simple and labor-saving, and it can realize the fixed-point storage of the trolley, avoid the trolley being placed randomly and occupying the medical passage, improve the cleanliness of the ward environment and the safety of passage. The V-shaped clamping groove on the clamp can be adapted to trolley frames of different diameters. With the help of the outward expansion guide plate, the alignment difficulty is reduced and the reliability of use is improved.

[0027] 2. The present invention features a height adjustment mechanism that allows for flexible adjustment of the longitudinal height of the trolley fixing mechanism. Pulling the movable frame unlocks the height adjustment, and the mechanism automatically locks in place once adjusted. This design makes the invention suitable for nursing trolleys of different specifications and frame heights, thus broadening its applicability.

[0028] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0037] To make the technical means, creative features, objectives, and effects of this invention clearer and easier to understand, the invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0038] This invention proposes a nursing trolley management device, including an assembly plate 1. A groove is provided on the front side of the assembly plate 1, and a mounting frame 2 is fixedly connected within the groove. The assembly plate 1 is a roughly rectangular metal plate and can be fixedly installed on the ward wall, nurse station side wall, or other locations using expansion bolts, serving as the mounting base for the device. The mounting frame 2, which is a rectangular block, is fixedly connected to the groove of the assembly plate 1 by bolts. The mounting frame 2 is embedded in the groove for stable assembly. A front receiving cavity 201 is provided at the front end of the mounting frame 2, and a rear receiving cavity 203 is provided at the middle of the rear end of the mounting frame 2. The rear receiving cavity 203 and the front receiving cavity 201 are connected. A through slot 202 is provided between the two sides. The width of the through slot 202 is smaller than that of the rear receiving cavity 203 and the front receiving cavity 201. The mounting frame 2 forms a stepped cavity structure that is wider at the front, narrower in the middle, and wider at the back. It is used to accommodate functional components and form axial limiting. A trolley fixing mechanism 3 is provided in the front receiving cavity 201. The trolley fixing mechanism 3 is used to clamp and fix the transverse push rod of the nursing trolley, so as to realize the fixed storage of the nursing trolley. A height adjustment mechanism is provided between the trolley fixing mechanism 3 and the mounting frame 2. The height adjustment mechanism is used to adjust the longitudinal height of the trolley fixing mechanism 3 to adapt to the push frame height of different models of trolleys for fixed storage.

[0039] In this embodiment, as Figure 5 , Figure 6 and Figure 7As shown, the trolley retaining mechanism 3 includes a movable frame 301 disposed within the front receiving cavity 201. The movable frame 301 is a rectangular frame with an open front end. Two vertically symmetrically distributed clamping plates 303 are disposed inside the movable frame 301. A vertically arranged guide rod 304 is also fixedly connected inside the movable frame 301. Sliding holes adapted to the guide rod 304 are provided on the clamping plates 303. The clamping plates 303 and guide rods 304 are slidably connected, allowing the clamping plates 303 to slide vertically along the guide rods 304, ensuring the straightness of the opening and closing action of the clamping plates 303. Preferably, the number of guide rods 304 is not less than two, improving... To ensure the stability of the movement of the clamping plates 303, a first elastic element 305 is fixedly connected between the opposite sides of the two clamping plates 303 and the inner wall of the front receiving cavity 201. Under normal conditions, the elastic force of the first elastic element 305 pushes the two clamping plates 303 together to form a clamping force. In a preferred embodiment, the first elastic element 305 can be a compression spring. The number of first elastic elements 305 can be designed according to the clamping force requirements. The first elastic element is a 304 stainless steel compression spring with a wire diameter of 1.2mm, an outer diameter of 8mm, and a free length of 15mm. The working compression amount is 5~8mm, and the normal clamping force is not less than 30N.

[0040] In this embodiment, as Figure 6 As shown, each of the two clamping plates 303 has a clamping groove 3031 on one side opposite to the other. The clamping groove 3031 has a V-shaped structure design, which can be adapted to circular push rods of different diameters. The line contact improves the clamping stability and prevents the nursing trolley from shaking. In a preferred embodiment, the included angle of the V-shaped clamping groove 3031 can be 90° and the groove depth is 5mm, which can be adapted to circular push rods with diameters of φ16mm~φ32mm. Each of the two clamping plates 303 has an outwardly expanding guide plate 3032 at the end away from the moving frame 301. The outwardly expanding guide plate 3032 is integrally formed with the clamping plate 303 to form a trumpet-shaped entrance. In a preferred embodiment, the outward expansion angle of the outwardly expanding guide plate can be 30° and the maximum opening width of the entrance can be 50mm. The nursing trolley pusher can quickly slide into the clamping groove 3031 area along the guide slope of the outwardly expanding guide plate 3032, reducing the difficulty of the alignment operation.

[0041] In this embodiment, as Figure 3 and Figure 5 As shown, the height adjustment mechanism includes a positioning block 302 fixedly connected to the back of the movable frame 301. The inner wall of the front receiving cavity 201 has a plurality of positioning slots 2011 longitudinally provided at the corresponding position of the positioning block 302 for the positioning block 302 to be aligned and engaged. By engaging the positioning block 302 on the movable frame 301 into the positioning slots 2011 on the mounting bracket 2, the longitudinal position of the movable frame 301 is locked. Preferably, the number of positioning blocks 302 and positioning slots 2011 is not less than two sets, symmetrically arranged on both sides of the through groove 202 to improve the stability of locking the position of the movable frame 301.

[0042] In this embodiment, the height adjustment mechanism further includes a tension reset component 4, which is used to unlock and automatically reset the positioning block 302 when the height of the trolley fixing mechanism 3 is adjusted.

[0043] In this embodiment, as Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, the stretching reset assembly 4 includes a stop plate 401 disposed in the rear receiving cavity 203 and a guide shaft 402 fixedly connected to the back of the moving frame 301. The back of the stop plate 401 is provided with a receiving groove 4011 corresponding to the position of the guide shaft 402. A through hole is provided on the inner wall of the receiving groove 4011 to pass through the stop plate 401. One end of the guide shaft 402 passes through the through hole and is placed in the receiving groove 4011 and fixedly connected with a locking ring 403. A second elastic member 404 is disposed inside the receiving groove 4011 and between the locking ring 403 and the inner wall of the receiving groove 4011. The second elastic member 404 is sleeved on the outside of the guide shaft 402. Under normal conditions, the elastic force of the second elastic element 404 pushes the locking ring 403 to move backward, which in turn drives the moving frame 301 to press against the rear wall of the front receiving cavity 201 via the guide shaft 402, so that the positioning block 302 is stably engaged in the positioning slot 2011 and maintains a height-locked state. When the moving frame 301 is pulled forward, the guide shaft 402 drives the locking ring 403 to compress the second elastic element 404 forward, and the positioning block 302 simultaneously moves forward to disengage from the positioning slot 2011. At this time, the moving frame is released from height lock and can move up and down to adjust its position. In this specific embodiment, the number of receiving groove 4011, guide shaft 402, locking ring 403 and second elastic member 404 is not less than two sets to ensure that the position of the stop plate 401 will not deviate. In this embodiment, four sets are preferred. Preferably, the second elastic member 404 can be a compression spring. The second elastic member is a 304 stainless steel compression spring with a wire diameter of 1.5mm, an outer diameter of 10mm and a free length of 20mm. The compression amount in the locking state is 6~8mm to ensure that the positioning block 302 is stably engaged and does not disengage.

[0044] In this embodiment, as Figure 4 and Figure 8 As shown, a guide groove 2031 is provided vertically on the inner wall of the rear receiving cavity 203. Several guide rollers 405 placed in the guide groove 2031 are rotatably connected to the stop plate 401. When the moving frame 301 is adjusted up and down, the stop plate 401 moves up and down together. The guide rollers 405 roll along the guide groove 2031, converting sliding friction into rolling friction, reducing the resistance of height adjustment, and ensuring the stability and straightness of the movement process. Preferably, the number of guide grooves 2031 and guide rollers 405 is not less than two sets to improve the stability of the stop plate 401 during movement adjustment.

[0045] In this embodiment, as Figure 6 As shown, auxiliary pull plates 306 extending to the outside of the mounting frame 2 are fixedly connected to both sides of the movable frame 301. The auxiliary pull plates 306 are integrally formed with the movable frame 301. Medical staff can pull the movable frame 301 forward through the auxiliary pull plates 306, making the operation more labor-saving and convenient.

[0046] In this embodiment, as Figure 1 As shown, a positioning groove 101 is provided at the bottom of one side of the assembly plate 1, and a positioning protrusion 102 is provided at the bottom of the other side of the assembly plate 1, which is embedded in the positioning groove 101. When multiple sets of the nursing cart management device are installed side by side, the positioning protrusion 102 of the previous set of nursing cart management device can be embedded into the positioning groove 101 of the next set of device to achieve rapid alignment and splicing, and improve the positioning accuracy and installation efficiency of batch installation.

[0047] In this embodiment, the assembly plate 1, mounting bracket 2, movable frame 301, and clamping plate 303 are made of 304 stainless steel with a brushed surface to meet the requirements of medical disinfection and corrosion resistance; the guide roller 405 is made of medical-grade nylon.

[0048] The assembly plate 1 serves as the mounting base for the entire device, and a groove is formed on its front side. The mounting bracket 2 is fixedly connected to this groove, forming the main support body of the device. A front receiving cavity 201 is formed at the front end of the mounting bracket 2 to accommodate and guide the longitudinal movement of the trolley fixing mechanism 3; a rear receiving cavity 203 is formed at the middle of the rear end of the mounting bracket 2 to accommodate the rear end component of the height adjustment mechanism; a through groove 202 is formed between the front receiving cavity 201 and the rear receiving cavity 203, which extends longitudinally and is used for the transmission component connecting the internal components of the front receiving cavity 201 and the rear receiving cavity 203 to pass through. The width of the through groove 202 is designed to be smaller than the width of the rear receiving cavity 203 and smaller than the width of the front receiving cavity 201, thereby forming stepped limiting surfaces on the inner walls of the front receiving cavity 201 and the rear receiving cavity 203 respectively, to limit the maximum displacement stroke of the internal components and prevent the components from falling out.

[0049] A trolley securing mechanism 3 is installed in the front receiving cavity 201. This trolley securing mechanism 3 forms a detachable clamping and fixing engagement with the transverse push rod of the nursing trolley to achieve fixed-point storage of the trolley. A height adjustment mechanism is provided between the trolley securing mechanism 3 and the mounting frame 2. This height adjustment mechanism connects the trolley securing mechanism 3 and the mounting frame 2 in the longitudinal direction. By changing the longitudinal position of the trolley securing mechanism 3 in the front receiving cavity 201, the overall height of the trolley securing mechanism 3 can be adjusted to accommodate nursing trolley models with different push rod heights.

[0050] By setting up a linkage response component consisting of a force transmission rod and a response wedge, the height adjustment action does not require an additional unlocking switch or knob. Instead, it directly utilizes the longitudinal pressure applied by the operator to the cart retention mechanism 3 as the driving force. When medical staff need to adjust the height, they only need to press down on the moving frame 301 of the cart retention mechanism 3. The force transmission rod then pushes the response wedge to slide along the inner wall of the rear receiving cavity 203. The response wedge converts the vertical force into a horizontal component through its inclined wedge surface, forcing the stop plate 401 to move away from the inner wall of the rear receiving cavity 203, thereby completely disengaging the positioning block 302 from the positioning slot 2011. The entire unlocking process is completed simultaneously with the height adjustment operation, achieving a "press to unlock" one-handed blind operation effect, greatly simplifying the adjustment process and improving clinical efficiency.

[0051] When the longitudinal pressure is released, the response wedge automatically returns to its original position under the elastic force of the elastic reset member. Simultaneously, the stop plate 401 resets and pushes the positioning block 302 back into the corresponding height positioning slot 2011. This locking process requires no manual intervention and is completed automatically via mechanical linkage. This effectively prevents the trolley fixing mechanism 3 from slipping during use due to medical staff forgetting to lock it, thus ensuring the height stability of the nursing trolley after it is fixed and preventing the trolley from tipping over or medications from spilling due to changes in the fixing point height, thereby improving safety.

[0052] The force transmission rod, response wedge, and stop plate 401 employ a sliding engagement with an inclined wedge surface to transmit force. This decomposes the longitudinal load into a horizontal driving force through the inclined surface, and the force amplification effect ensures that even a small pressing force can reliably drive the stop plate 401 to complete the unlocking stroke. Simultaneously, this linkage response assembly is entirely enclosed within the front and rear receiving cavities 201 and 203, making it less susceptible to interference from external foreign objects. Its long-term performance remains stable, making it suitable for the high-frequency operating environment of hospitals.

[0053] One-way movement restriction prevents accidental slippage. An anti-slip locking device consisting of a retaining ring and retaining claws is installed within the through groove 202. Multiple one-way retaining grooves are spaced axially on the outer peripheral wall of the retaining ring, ensuring that the retaining claws remain in a one-way engaged state with the retaining grooves under the action of the return torsion spring. When the positioning block 302 completely disengages from the positioning groove 2011, the cart retaining mechanism 3 can only move in one direction—for example, it can only adjust downwards and cannot spring back upwards, or vice versa. This one-way restriction mechanism ensures that even if the medical staff accidentally releases their hand during operation or if the cart retaining mechanism 3 is subjected to vibration or impact, it will not experience uncontrolled bidirectional free sliding, effectively avoiding the risk of the cart falling off due to sudden changes in height.

[0054] The anti-disengagement locking device acts as a second locking line of defense, independent of the engagement between the positioning block 302 and the positioning slot 2011, providing "dynamic protection" during height adjustment. Even when the positioning block 302 is suspended and not engaged with any of the positioning slots 2011, the anti-disengagement locking device still provides reliable displacement restriction, preventing the trolley securing mechanism 3 and the nursing trolley from falling down. This structural design significantly improves the safety redundancy of the device during adjustment operations, making it particularly suitable for nursing trolleys carrying medications or fragile instruments.

[0055] The tooth profile of the anti-reverse groove is configured to block in only one direction. In the opposite direction, the anti-reverse claw can smoothly slide through the anti-reverse groove without generating substantial resistance. Therefore, the anti-disengagement lock will not interfere with normal downward pressing and adjustment operations, maintaining a good operating feel and achieving a balance between safety and convenience.

[0056] Visual feedback on clamping status enhances operational certainty. A purely mechanical clamping positioning detection and feedback system is constructed by embedding a trigger plate at the bottom of the clamping groove 3031 and installing a trigger link and a positioning indicator block within the moving frame 301. When the lateral push rod of the nursing cart is fully engaged at the bottom of the clamping groove 3031 and sufficient clamping force is applied, the push rod presses against the trigger plate. The trigger plate, through a push post, drives the trigger link to slide along the inside of the moving frame 301, thereby pushing the positioning indicator block out from the outer wall of the moving frame 301. Medical staff can visually determine whether the cart has been reliably clamped and fixed by observing the extension status of the positioning indicator block, avoiding cart loosening due to inadequate clamping and effectively improving operational reliability.

[0057] The entire adaptive clamping trigger assembly operates entirely on the principle of mechanical linkage, without relying on any electrical components or sensors. This reduces manufacturing costs and avoids signal failures caused by aging electrical wiring or poor contact during frequent push-pull operations. This mechanical feedback structure boasts an extremely long service life and strong anti-interference capabilities, making it particularly suitable for complex conditions in hospital environments, such as disinfectant wiping and liquid splashing.

[0058] The trigger position for the pressure plate is located at the bottom of the clamping groove 3031. This means that the positioning indication will only be triggered when the push rod overcomes the elastic force of the first elastic element 305 and fully enters the bottom of the clamping groove 3031, rather than generating false feedback when the push rod is only partially engaged. This "deep-position triggering" design ensures a strict correspondence between the positioning indication signal and the actual clamping and locking state, avoiding safety hazards caused by false prompts.

[0059] By installing a wall-mounted base on the rear side of the mounting plate 1, and a deflection adjustment assembly consisting of an arc-shaped adjustment rail and a guide slider between the wall-mounted base and the mounting plate 1, the mounting plate 1 can be deflected at an angle relative to the wall-mounted base in the horizontal plane. The guide slider is fitted into the arc-shaped adjustment rail and slides along its arc direction. When it slides to the desired angle, it is locked by inserting a positioning pin into the corresponding angle positioning hole. This design allows the management device installed on the wall to flexibly adjust the outward angle of the trolley fixing mechanism 3 according to the specific direction of the ward corridor and the spatial layout of the nurse station, so that the nursing trolley can form an optimal angle with the direction of the passage after being parked, which is convenient for pushing and retrieving, and minimizes the occupation of passage space.

[0060] The curved adjustment rail has multiple angle positioning holes along its arc, each corresponding to a specific deflection angle, such as -30°, 0°, and +30°. Medical staff can select the most suitable fixed angle based on the actual channel width, trolley length, and daily pushing route. The insertion and engagement between the positioning pin and the angle positioning hole is simple to operate and reliable, and will not drift due to vibration during long-term use, ensuring the consistency of the trolley's parking orientation and contributing to the standardized, visualized, and unified management of the ward environment.

[0061] The wall-mounted base is installed independently of the assembly plate 1. During installation, the wall-mounted base is first fixed to the wall using expansion bolts, then the assembly plate 1 is assembled with the arc-shaped adjustment rail using guide sliders, and finally locked in place by positioning pins. This layered installation method reduces on-site construction difficulty, allowing installers to fix the base first without precise alignment, and then make minor angle adjustments. This improves installation efficiency and facilitates later maintenance or replacement of the entire management device.

[0062] Working principle: When in use, it is fixed to the ward wall, the nurse station side wall, etc. by expansion bolts. If multiple sets of devices need to be installed side by side, the positioning protrusion 102 of the first set of assembly plate 1 in the two adjacent sets is aligned and embedded into the positioning groove 101 of the second set of assembly plate 1 to achieve quick horizontal alignment, and all devices are spliced ​​and fixed in sequence.

[0063] Then, based on the height of the trolley frame to be stored, the longitudinal height of the trolley fixing mechanism 3 is pre-adjusted. Medical staff hold the auxiliary pull plates 306 on both sides of the moving frame 301 and pull the moving frame 301 horizontally forward. The moving frame 301 drives the guide shaft 402 on its back to move forward synchronously. The locking ring 403 at the end of the guide shaft 402 moves forward accordingly, compressing the second elastic element 404 in the receiving groove 4011. Simultaneously, the positioning block 302 on the back of the moving frame 301 moves forward synchronously, completely disengaging from the positioning slot 2011 on the inner wall of the front receiving cavity 201 of the mounting frame 2, releasing the longitudinal lock of the moving frame 301. Maintaining the forward-pulling state, the moving frame 301 is moved upward or downward to... During the movement at the target height, the stop plate 401 moves longitudinally synchronously with the guide shaft 402 and the moving frame 301. The guide roller 405 on the stop plate 401 rolls along the guide groove 2031 on the inner wall of the rear receiving cavity 203, converting sliding friction into rolling friction and reducing adjustment resistance. After the height is adjusted to the correct position, the auxiliary pull plate 306 is released, and the compressed second elastic element 404 releases its elastic force, pushing the locking ring 403 to reset backward. Through the guide shaft 402, the moving frame 301 is driven to press against the rear wall of the front receiving cavity 201, so that the positioning block 302 is aligned and locked into the positioning slot 2011 of the corresponding height, automatically completing the height locking. The height adjustment of the trolley fixing mechanism 3 is completed.

[0064] When the nursing trolley needs to be stored away at a designated location, align the lateral push rod of the trolley with the funnel-shaped entrance formed by the outward-expanding guide plate 3032 at the front end of the two clamping plates 303, and push the trolley inward. The push rod gradually squeezes into the space between the two clamping plates 303 along the inclined surface of the outward-expanding guide plate 3032, applying a reverse compressive force to the upper and lower clamping plates 303, causing the two clamping plates 303 to separate upward and downward along the guide rod 304. At the same time, the first elastic element 305 on the corresponding side is compressed. When the push rod slides completely into the V-shaped clamping groove 3031 of the clamping plate 303, the compressive force disappears, and the compressed first elastic element 305 releases its restoring elastic force, pushing the two clamping plates 303 towards each other along the guide rod 304. The push rod is clamped by the V-shaped clamping groove 3031, relying on the elasticity... The clamping force secures the nursing trolley in place. The V-shaped clamping groove 3031 can accommodate push rods of different diameters, ensuring stable clamping and preventing the trolley from shaking. When the nursing trolley needs to be retrieved, hold the trolley pusher and pull it horizontally outward. The pusher applies an outward force to the inner wall of the V-shaped clamping groove 3031, pushing the upper and lower clamping plates 303 to separate in the opposite direction along the guide rod 304. This compresses the first elastic element 305 again, gradually widening the clamping opening. As the trolley is pulled outward continuously, the pusher completely disengages from between the two clamping plates 303 along the inclined surface of the outward-expanding guide plate 3032. After the clamping plates 303 lose their squeezing force, the first elastic element 305 automatically resets, causing the two clamping plates 303 to return to their initial close-up state. The device returns to its ready-to-use state, completing the trolley retrieval.

A reset torsion spring is connected between the backstop claw and the inner wall of the through groove (202). Under the action of the reset torsion spring, the backstop claw always tends to deflect toward the backstop ring. Several one-way backstop grooves are provided axially at intervals on the outer peripheral wall of the backstop ring. The one-way backstop grooves engage with the backstop claw in one direction to restrict the trolley fixing mechanism (3) to move only in one direction after the positioning block (302) is disengaged from the positioning slot (2011), so as to prevent the trolley fixing mechanism (3) from accidentally slipping due to misoperation.
