Description

Technical Field

[0001] This utility model relates to the field of headrest technology, and more specifically, to a microscope headrest with height adjustment support. Background Technology

[0002] Microscopes are widely used as essential observation and analysis tools in industries, education, and healthcare. However, traditional microscope headrests typically lack personalized height adjustment, making them difficult to adapt to the needs of different users. This not only affects work efficiency but can also lead to user discomfort or even health problems due to improper posture. Especially in crowded environments such as hospitals and schools, sharing microscope equipment, particularly the eyepiece which comes into direct contact with the eye, becomes a high-risk factor for cross-infection.

[0003] While existing microscope headrests offer height adjustment via adjustable mechanisms, this is currently only possible through manual adjustment. Users often need to repeatedly adjust the height in situations requiring frequent adjustments or high precision, which is not only time-consuming and laborious but also significantly reduces ease of use and efficiency. Furthermore, in crowded environments, due to high usage frequency, if the headrest tray is not cleaned promptly after prolonged use, it can easily become a breeding ground and transmission medium for bacteria, viruses, and other pathogens.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a microscope head support with height adjustment support to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A microscope head holder with height-adjustable support includes a base plate; a fixing component located at the bottom of the base plate, which stably fixes the microscope head holder to ensure structural stability during use; a mounting cylinder located at the top of the base plate; a lifting component located inside the mounting cylinder, which drives the microscope head holder to reciprocate vertically to achieve precise height adjustment and positioning of the head holder; a head holder located at the top of the lifting component; a winding component located inside the head holder, with sterile gauze wrapped around it for automatic winding and unwinding, effectively preventing cross-contamination between different users; and a controller located at the top of the base plate.

[0008] Furthermore, to improve the stability of the head bracket fixation and achieve rapid release and positioning, the fixing assembly includes several suction components located at the bottom of the base plate, with a wind-blocking component on top of each suction component. Each suction component includes a suction nozzle located at the bottom of the base plate, with a ventilation hole in the center of the nozzle that mates with the wind-blocking component. The wind-blocking component includes a circular groove inside the base plate, with a circular turntable inside the groove. The outer circumference of the circular turntable has an arc-shaped groove that mates with the ventilation hole; a lever is located on the outer circumference of the arc-shaped groove.

[0009] Furthermore, to achieve height adjustment of the microscope holder, the lifting assembly includes a cross link housed inside the mounting cylinder. A bearing is housed inside the cross link, and a rotating shaft is fitted onto the inner circumference of the bearing. Two sets of spiral grooves are formed on the outer circumference of the rotating shaft, and these grooves are staggered. The bottom end of the rotating shaft is connected to the output end of a servo motor. A driven component is located at the top of the rotating shaft. The driven component includes a sleeve mounted on the outer circumference of the rotating shaft. A pin is movably mounted on the circumference side wall of the sleeve. An arc-shaped plate that mates with the spiral grooves is located on the side of the pin closest to the rotating shaft. Several circumferentially arranged receiving plates are provided on the outer circumference of the sleeve. A support seat that mates with the mounting cylinder is located on the outer wall of the receiving plates. Several sliding strips are provided on the outer wall of the support seat.

[0010] Furthermore, to ensure a smooth and stable lifting process and to avoid deviation or shaking, the inner wall of the mounting cylinder is provided with slide rails that cooperate with several slide bars.

[0011] Furthermore, in order to achieve good contact fit and motion transmission, the curvature of the arc plate is the same as that of the spiral groove.

[0012] Furthermore, in order to achieve automatic replacement and recycling of sterile gauze and improve the hygiene and safety of the equipment and the ease of operation, the winding assembly includes slots symmetrically arranged at one end of the head bracket, and rollers one, two, and three are arranged sequentially inside the slots; the outer circumference of the two sets of rollers one is respectively fitted with a new material roll and a waste material roll; the end of roller one located at the waste material roll passes through the head bracket and is connected to the crank handle.

[0013] Furthermore, to provide good ventilation in the chin contact area and avoid stuffiness or discomfort caused by prolonged contact, a breathable sheet is provided at the inner top of the headrest and at the bottom of the sterile gauze.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. This utility model features a reasonable and reliable structure and simple operation. By incorporating a fixing component, the base plate is firmly connected to the tabletop, ensuring structural stability. Users can quickly lock or release the device by simply rotating a lever, enhancing operational convenience and safety. Simultaneously, the lifting component allows for flexible adjustment of the headrest height according to different heights and experimental needs, effectively improving operational comfort and image acquisition stability. Furthermore, the winding component automatically unfolds and retracts the sterile gauze before and after each use, reducing direct contact between the user and the headrest, effectively avoiding the risk of pathogen transmission, and thus improving the hygiene, safety, and operational reliability of the equipment in high-frequency, multi-user scenarios.

[0016] 2. This utility model, by setting up a fixing component, uses an adsorption method to firmly connect the base plate to the table surface, thereby achieving stable support for the microscope head holder and effectively ensuring its structural stability and operational reliability during use. Users can quickly complete the adsorption locking or release operation with a simple rotation of the lever, thus improving the ease of operation, efficiency, and safety of the equipment.

[0017] 3. This utility model, by incorporating a lifting component, allows users to flexibly adjust the height of the microscope head support according to actual needs, thereby better accommodating operators of different heights and diverse experimental scenarios, significantly improving operational comfort and image acquisition stability. Simultaneously, the servo motor operates only in the forward direction, simplifying the operating mechanism and effectively extending the equipment's lifespan while ensuring flexible adjustment, further enhancing the device's practicality.

[0018] 4. This invention, by incorporating a winding component, automatically unfolds and retracts the sterile gauze before and after each use, forming an effective physical barrier and reducing direct contact between the user and the headrest. This effectively avoids the potential spread of pathogens due to untimely or inadequate cleaning of the headrest, thereby improving the hygiene, safety, and operational reliability of the device in scenarios involving multiple users using it continuously.

[0030] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0031] According to an embodiment of the present invention, a microscope head holder with height-adjustable support is provided.

[0032] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-8 As shown, a microscope head holder with height-adjustable support according to an embodiment of the present invention includes a base plate 1; a fixing component 2, disposed at the bottom of the base plate 1, which stably fixes the microscope head holder to ensure its structural stability during use; a mounting cylinder 3, disposed at the top of the base plate 1; a lifting component 4, disposed inside the mounting cylinder 3, which drives the microscope head holder to reciprocate vertically to achieve precise adjustment and positioning of the head holder height; a head holder 5, disposed at the top of the lifting component 4; a winding component 6, disposed inside the head holder 5; sterile gauze 8, which is wrapped around the winding component 6 and automatically retracts and expands, effectively avoiding cross-contamination between different users; and a controller 7, disposed at the top of the base plate 1.

[0033] By utilizing the aforementioned technical solution of this utility model, the base plate 1 is firmly connected to the tabletop by setting the fixing component 2, ensuring structural stability. Users can quickly lock or release the device simply by rotating the lever 2024, improving operational convenience and safety. Simultaneously, the lifting component 4 can flexibly adjust the height of the headrest 5 according to different heights and experimental needs, effectively improving operational comfort and image acquisition stability. Furthermore, the winding component 6 automatically unfolds and retracts the sterile gauze 8 before and after each use, reducing direct contact between the user and the headrest 5, effectively avoiding the risk of pathogen transmission, and thus improving the hygiene safety and operational reliability of the equipment in high-frequency, multi-user scenarios.

[0034] Specifically, the controller 7 is equipped with a human-machine interface and a PLC (programmable logic controller). The human-machine interface is the interaction interface between the operator and the automation system. Its main function is to display the real-time operating status and the input of control commands. The PLC is used to execute specific control tasks, such as switch and sensor signal acquisition and processing.

[0035] In one embodiment, the fixing component 2 includes several suction members 201 disposed at the bottom end of the base plate 1, and a wind-blocking component 202 disposed at the top of the suction member 201. The suction member 201 includes a suction nozzle 2011 disposed at the bottom end of the base plate 1, and a ventilation hole 2012 cooperating with the wind-blocking component 202 is opened in the middle of the suction nozzle 2011. The wind-blocking component 202 includes a circular groove 2021 disposed inside the base plate 1, and a circular turntable 2022 disposed inside the circular groove 2021. An arc-shaped groove 2023 cooperating with the ventilation hole 2012 is opened on the outer circumference of the circular turntable 2022; a lever 2024 is disposed on the outer circumference of the arc-shaped groove 2023. This not only improves the stability of the head bracket 5 but also achieves rapid release and positioning functions.

[0036] The working principle of the fixing component 2 is as follows: After the microscope is placed in position, the head bracket 5 is aligned with the fixing surface of the microscope for installation. The suction nozzle 2011 adheres to the surface under gravity, and the internal air is naturally discharged through the ventilation hole 2012. At this time, the lever 2024 is moved, causing the circular turntable 2022 to rotate until the arc groove 2023 is misaligned with the ventilation hole 2012, and the solid part of the turntable completely covers the opening, forming a sealed cavity. The pressure difference between the external atmospheric pressure and the internal pressure of the suction nozzle drives the silicone suction nozzle to adhere tightly to the surface, achieving stable installation of the fixing component 2. After use, simply reverse the lever 2024 to realign the arc groove 2023 with the ventilation hole 2012, and the internal and external air pressures quickly balance. The suction nozzle 2011 loses its pressure difference support, allowing the bracket to be easily removed or its position adjusted.

[0037] It should be explained that both the suction nozzle 2011 and the circular turntable 2022 are made of rubber and are used to seal the ventilation hole 2012. The rubber material has good elasticity and sealing performance, and can provide reliable airtightness under different pressure conditions.

[0038] In one embodiment, the lifting assembly 4 includes a cross link 401 disposed inside the mounting cylinder 3. A bearing 402 is disposed inside the cross link 401. A rotating shaft 403 is sleeved on the inner circumference of the bearing 402. Two sets of spiral grooves 404 are formed on the outer circumference of the rotating shaft 403, and the two sets of spiral grooves 404 are staggered. The bottom end of the rotating shaft 403 is connected to the output end of the servo motor 405. A follower 406 is disposed on the top of the rotating shaft 403. The driven member 406 includes a sleeve 4061 disposed on the outer circumferential wall of the rotating shaft 403. A pin 4062 is movably disposed on the circumferential side wall of the sleeve 4061. An arc-shaped plate 4063 that mates with a spiral groove 404 is disposed on the side of the pin 4062 near the rotating shaft 403. A plurality of circumferentially arranged receiving plates 4064 are disposed on the outer circumferential wall of the sleeve 4061. A support base 4065 that mates with the mounting cylinder 3 is disposed on the outer wall of the plurality of receiving plates 4064. A plurality of slide bars 4066 are disposed on the outer wall of the support base 4065. Thus, the rotational motion of the servo motor 405 is converted into the vertical lifting motion of the driven member 406, realizing the height adjustment of the microscope holder.

[0039] The specific working principle of the lifting assembly 4 is as follows: By pressing the button on the controller 7, the servo motor 405 is started to rotate forward, and its output end drives the rotating shaft 403 to rotate. Since the rotating shaft 403 has two sets of staggered spiral grooves 404, when the rotating shaft rotates, the arc plate 4063 on the driven member 406 cooperates with the spiral grooves 404. The servo motor 405 only needs to continue to rotate forward to move the sleeve 4061 to the top along one set of spiral grooves 404. When the rotating shaft 403 reaches the upper limit position, since the spiral grooves 404 are staggered, the arc plate 4063 will automatically switch to the other set of spiral grooves 404 and slide along it in the opposite direction, thereby realizing reciprocating motion. During the movement of the sleeve 4061, the receiving plate 4064 moves synchronously, thereby driving the support base 4065 and the slide bar 4066 to slide in the mounting cylinder 3, ultimately realizing the overall lifting function of the lifting assembly 4. When it is necessary to stop lifting, release the button on the controller 7 to stop the servo motor 405 from running, and the lifting assembly 4 can be stably maintained at the current height.

[0040] In one embodiment, the inner wall of the mounting cylinder 3 is provided with slide rails 9 that cooperate with a plurality of slide bars 4066. This ensures a smooth and stable lifting process and avoids deviation or shaking.

[0041] In one embodiment, the curvature of the arc plate 4063 is the same as that of the spiral groove 404. This achieves good contact fit and motion transmission.

[0042] In one embodiment, the winding assembly 6 includes slots 601 symmetrically arranged at one end of the head bracket 5. Rollers 602, 603, and 604 are sequentially arranged inside the slots 601. New material rolls 606 and waste material rolls 607 are respectively fitted onto the outer circumferential walls of the two sets of rollers 602. One end of the roller 602 located at the waste material roll 607 passes through the head bracket 5 and is connected to the crank handle 605. This not only achieves automatic replacement and recycling of the sterile gauze 8 but also effectively improves the hygiene and safety of the equipment and the ease of operation.

[0043] The specific working principle of the winding assembly 6 is as follows: When a winding operation is required, the user cranks the handle 605 to rotate the roller 602. Since the waste roll 607 is fitted onto the outer circumference of the roller 602, the rotation of the roller 602 will simultaneously drive the waste roll 607, which in turn drives the new roll 606 to rotate synchronously. During the rotation, the waste roll 607 continuously winds up the used material, while the new roll 606 continuously releases new sterile gauze 8, thereby achieving the orderly recycling and replacement of the used sterile gauze 8. The rollers 603 and 604 play a guiding and supporting role during the winding process, ensuring that the sterile gauze 8 can be smoothly wound onto the new roll 606 and the waste roll 607. Since the head bracket 5 has an arc-shaped internal structure, the new roll 606 and the waste roll 607 can remain horizontal under the support of the two sets of rollers 604. After replacement, the user only needs to place their chin on the head support 5 and press the sterile gauze 8 tightly against it. The new roll of material 606 will then automatically expand and contract to complete the protective coverage of the contact area.

[0044] It should be explained that when it is necessary to replace the new material roll 606 and the waste material roll 607, the staff removes the cover plate on one side of the head bracket 5 with bolts and replaces it. After installation, the staff pulls out sterile gauze 8 from the new material roll 606, wraps it around the top of the head bracket 5, and then wraps it around the roller 602 at the crank handle 605. The staff then tightens it by cranking the crank handle 605 and installs the cover plate, thus achieving the replacement effect.

[0045] In one embodiment, a breathable sheet 10 is provided at the inner top of the headrest 5 and at the bottom of the sterile gauze 8. This provides good ventilation for the chin contact area, avoiding stuffiness or discomfort caused by prolonged contact.

[0046] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0047] like Figures 1-8As shown, in practical applications, the controller 7 is electrically connected to the servo motor 405. First, after the user places the microscope in position, the head support 5 is aligned with the fixed surface of the microscope for installation. After adjustment, under the action of gravity, the suction nozzle 2011 fits tightly against the support surface (the specific working principle of the fixing component 2 is as described above). Subsequently, by moving the lever 2024, the base plate 1 is stably fixed. After the user places their head on the head support 5, they press the button on the controller 7 to control the servo motor 405 to rotate forward (the specific working principle of the lifting component 4 is as described above), driving the rotating shaft 403 to rotate. Since the outer wall of the rotating shaft 403 is provided with staggered spiral grooves 404, which cooperate with the arc plate 4063, the sleeve 4061 moves axially, thereby driving the receiving plate 4064, the support base 4065 and the slide bar 4066 to move synchronously, realizing smooth lifting and lowering within the mounting cylinder 3. Once the headrest is raised to the appropriate height, release the button. The servo motor 405 will stop running, and the lifting assembly 4 will remain at the set height. After use, press another button on the controller 7 and crank the handle 605 to rotate (the specific working principle of the winding assembly 6 is described above). This will cause the waste roll 607 to rotate, simultaneously pulling the sterile gauze 8 to complete the automatic replacement, effectively reducing direct contact between the user and the headrest 5 and improving hygiene and safety.

[0048] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly.
