Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a thermometer dropper. Background Technology

[0002] Thermometer shakeout machines are a common auxiliary device widely used in medical institutions and home environments. Their main function is to quickly reset the thermometer reading through centrifugal force.

[0003] In practical use, current thermometer droppers typically involve simply placing the thermometer in a square slot arranged in an outward "V" shape relative to the rotating shaft. This slot is structurally simple, consisting of a basic square recess, and lacks effective restraint or fixation for the thermometer. When the operator starts the device, the dropper uses centrifugal force generated by high-speed rotation to fling the mercury column from the thermometer. However, because the contact between the thermometer and the square slot is only point or line contact, the friction is insufficient and there is a gap due to movement. During high-speed rotation, the thermometer is highly susceptible to detaching from the slot due to vibration and centrifugal force. This not only risks the thermometer breaking but also poses safety risks such as mercury contamination and glass shards. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a thermometer drop device that can fix the thermometer and prevent it from being thrown off the device.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A thermometer dropper includes a turntable body with a placement slot for holding a thermometer. A distinguishing feature is the inclusion of a clamping mechanism detachably mounted on the turntable body and located on one side of the placement slot. The clamping mechanism includes a pressure plate that can move up and down relative to the turntable body. The pressure plate has a clamping portion covering the placement slot, which clamps and secures the thermometer placed in the slot by applying downward pressure.

[0007] In some embodiments, the clamping mechanism further includes a base, a limiting block, a guide rod, and a spring; the base is detachably mounted on the turntable body, and its upper surface is connected to its lower surface with at least one guide hole; the guide rod is vertically and movably inserted into the guide hole, and its bottom end is provided with a limiting ring; the limiting block is fixedly mounted on the upper surface of the base, and its upper surface is provided with a through hole through which the guide rod can movably pass; the spring is sleeved on the guide rod, one end of which abuts against the limiting ring, and the other end abuts against the limiting block, thereby applying a downward elastic force to the clamping part of the pressure plate; the pressure plate is connected to the top end of the guide rod.

[0008] In some embodiments, the thermometer dropper further includes a cover and a locking screw. The cover can cover the top of the turntable body, and the locking screw passes through the cover and is threaded to the center of the turntable body to press and fix the cover onto the turntable body.

[0009] Compared to existing technologies, this invention achieves at least the following beneficial effects: This invention directly constrains the thermometer by applying downward pressure from the pressure plate, effectively eliminating the risk of it detaching from the placement slot during high-speed rotation. This avoids safety hazards such as mercury leakage and flying glass shards caused by thermometer breakage, thus improving the safety of the equipment. Simultaneously, the lifting and lowering movement of the pressure plate can accommodate thermometers of different sizes, enhancing the versatility and adaptability of the dropping machine.

[0015] The present invention will now be described in detail with reference to exemplary embodiments shown in the accompanying drawings. However, it should be understood that the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present invention more complete and to fully convey the concept of the present invention to those skilled in the art.

[0016] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0017] like Figures 1 to 3 As shown, the thermometer dropping mechanism of this utility model includes a turntable body 1 and a pressing mechanism 2. The turntable body 1 has a placement slot 11 for accommodating the thermometer. The pressing mechanism 2 is detachably mounted on the turntable body 1 by hexagonal socket screws 3 and is located on one side of the placement slot 11. The pressing mechanism 2 includes a pressure plate 25 that can move up and down relative to the turntable body 1. The pressure plate 25 has a pressing part covering directly above the placement slot 11. The pressing part presses and fixes the thermometer placed in the placement slot 11 by downward pressure.

[0018] In this embodiment, the bottom of the turntable body 1 of the slinger is equipped with a motor to drive its rotation. A power cord for connecting to a power source, a rocker switch for starting the motor, and a timer button for selecting 30 or 60 seconds of rotation are located on the outside of the slinger. The placement slot 11 is a square slot. In this embodiment, there are three placement slots 11, evenly distributed on the turntable in an "outward octagonal" pattern to accommodate the direction of centrifugal force. The pressing part is the pressure plate 25 itself, a one-piece square plate that protrudes from the pressure plate 25 towards the placement slot 11.

[0019] refer to Figure 3 Specifically, the clamping mechanism 2 also includes a base 21, a limiting block 22, a guide rod 23, and a spring 24. The base 21 is detachably mounted on the turntable body 1, and its upper surface has at least one guide hole connected to its lower surface. The guide rod 23 is vertically and movably inserted into the guide hole, and its bottom end has a limiting ring 231. The limiting block 22 is fixedly mounted on the upper surface of the base 21 by countersunk screws, and its upper surface has a through hole 221 that movably passes through the guide rod 23. The spring 24 is sleeved on the guide rod 23, with one end abutting against the limiting ring 231 and the other end abutting against the limiting block 22, thereby applying a downward elastic force to the clamping part of the pressure plate 25. The pressure plate 25 and the top end of the guide rod 23 are also connected by countersunk screws.

[0020] The base 21 serves as a mounting platform, mounted on the turntable body 1 and located on the side of the placement slot 11 facing the axis of the turntable body 1. The bottom of the base 21 has a connecting lug 211 with a slotted hole 2111. The base 21 is detachably threaded to the turntable body 1 via an internal hexagonal screw 3 passing through the slotted hole 2111. The design of the slotted hole 2111 allows for fine-tuning of the base 21's mounting position before use, ensuring that the pressure plate 25 is accurately aligned with the placement slot 11, enhancing assembly flexibility and tolerance.

[0021] The limiting ring 231 is welded and fixed to the lower end of the guide rod 23. The number of guide rod 23, spring 24, and through holes 221 on the limiting block is equal to the number of guide holes. In this embodiment, there are two guide holes, two guide rods 23, two springs 24, and two through holes 221. This arrangement avoids the drawback of the pressure block rotating when there is only a single guide rod 23. The outer diameter of the limiting ring 231 is slightly smaller than the inner diameter of the guide hole, and the inner diameter of the through hole 221 is slightly larger than the outer diameter of the guide rod 23. In this way, the guide rod 23 can freely rise and fall through the guide hole and the through hole 221.

[0022] To ensure that the clamping mechanism can reliably hold the thermometer while preventing it from being crushed, the selection and installation of the spring 24 must ensure that the elastic force it provides meets the following functional requirements: the spring 24 is a compression spring, and its stiffness is such that when the pressure plate 25 is pressed down to contact and clamp the thermometer, the downward clamping force provided by the spring 24 is sufficient to prevent the thermometer from falling out of the placement slot 11 under the centrifugal force and vibration generated by the high-speed rotation of the dropper; at the same time, this clamping force is combined with the buffering effect of the buffer pad 252, and its maximum value is limited to a safe range that is not enough to crush the thermometer glass tube.

[0023] A handle 251 is attached to the pressure plate 25 for easy upward lifting. In this embodiment, the handle 251 is an inverted U-shaped handle. This design allows medical staff to easily lift the pressure plate 25 by hand to overcome the spring force, thereby freeing up space in the placement slot 11 for inserting or removing the thermometer.

[0024] A buffer pad 252 is attached to the lower surface of the pressing part of the pressure plate 25. In this embodiment, the buffer pad 252 is made of a flexible material such as sponge or rubber. This design prevents the hard pressure plate 25 from directly impacting the glass thermometer when it is pressed down, thus preventing it from breaking; at the same time, the elastic deformation of the material increases the friction between the thermometer and the thermometer, making the fixation more stable and reliable.

[0025] refer to Figure 2 Specifically, the thermometer dropper also includes a cover 4 and a locking screw 5. The cover 4 can cover the top of the turntable body 1, and the locking screw 5 passes through the cover 4 and is threaded to the center of the turntable body 1 to press and fix the cover 4 onto the turntable body 1.

[0026] The turntable body 1 has an annular step on its top outer surface for positioning the cover 4. The cover 4 has a through hole in its center, and the turntable body 1 has a threaded hole in its upper surface center. The lower end of the locking screw 5 passes through this through hole and is screwed into the threaded hole in the center of the turntable body 1. When the locking screw 5 is tightened, the nut will press the cover 4 firmly against the turntable, forming a fully enclosed protective cover. With this design, even in the extremely rare event that the thermometer is thrown out, the cover 4 can completely confine the thermometer inside the dropping mechanism.

[0027] The thermometer dropper is used as follows: First, medical personnel lift the handle 251 upwards, causing the pressure plate 25 to rise. Then, place the thermometer into the placement slot 11 on the turntable. Next, slowly lower the handle 251; the pressure plate 25 automatically presses down under the restoring force of the spring 24, its clamping part firmly holding the thermometer in place. After securing it, start the device; the turntable rotates, generating centrifugal force to drop the mercury column from the thermometer. After use, simply lift the pressure plate again to remove the thermometer.

[0028] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
