Description

Technical Field

[0001] This utility model relates to the field of pathological examination equipment technology, specifically a self-locking staining machine hanger assembly that is compatible with multi-size slide holders. Background Technology

[0002] With the development of intelligent medical equipment both domestically and internationally, routine HE staining procedures in pathology departments are now generally completed by fully automated staining machines. These machines typically come with a detachable staining carrier consisting of two parts: a suspension base (i.e., a hanger) and a slide holder. The latter is fixed by insertion through positioning holes on both sides and stainless steel guide rods with hooks. In practice, when stained slides need to be sealed, technicians must separate the hanger from the slide holder. Since the length of the hanger is fixed, the conventional separation method requires manual pulling of the metal hooks. This physical disassembly method has significant drawbacks: repeated lateral torsion over a long period can cause deformation of the metal hook structure, leading to the hooks, originally perpendicular to the hanger body, gradually tilting outwards and creating a loose fit with the slide holder. When the fully automated staining machine is running, this loose connection can easily cause the slide holder to accidentally detach, leading to serious consequences such as glass slide breakage and equipment interruption, posing a continuous risk to the stability of pathological examination work. Utility Model Content

[0003] This utility model provides a self-locking staining machine hanger assembly that is compatible with various sizes of slide holders. It can solve the problem that the metal hooks of existing slide holder hangers are prone to deformation when disassembling and assembling with the slide holder, which can cause the slide holder to fall off accidentally.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-locking staining machine hanger assembly adaptable to multi-specification slide holders, comprising a hanger body, wherein sliding cavities are provided at both ends of the hanger body, and sliding blocks that can extend and retract along the ends of the hanger body are installed inside the sliding cavities. Hooks for connecting to both ends of the slide holders are vertically connected to the lower ends of the sliding blocks. Locking pins that can move back and forth are installed on the sidewalls of the hanger body corresponding to the sliding cavities. Multiple locking pins that engage with the locking pins are provided on the sidewalls of the sliding blocks. The positioning hole disengages from the locking pin when it moves forward. A dyeing machine robotic arm connecting plate is installed on the upper middle part of the main body of the bracket. The end of the sliding block is provided with a downward-facing recessed groove. The recessed groove matches the auxiliary hook on the dyeing agent robotic arm. The distance between the two hooks can be adjusted by setting a movable sliding block. When the hook is disassembled from the slide holder, it can be disassembled simply by moving the sliding block. The hook will not deform. Moreover, the sliding block can achieve multiple settings through the cooperation of the locking pin and the positioning hole to adapt to different specifications of slide holders.

[0005] Preferably, the top of the sliding cavity is open, and a cover plate covering the sliding cavity is provided on the upper side of the main body of the bracket. A sliding groove is provided in the middle of the cover plate, and a guide protrusion is provided on the top of the sliding block, which is embedded in or passes through the sliding groove. The guide protrusion can not only guide the sliding of the sliding block, but also allow the operator to quickly drive the sliding block to slide.

[0006] Preferably, a spring is fitted on the outer side of the locking post. The spring keeps the locking post engaged with the positioning hole and keeps the locking post in the locked position, ensuring the safety of the bracket assembly when connected to the slide holder.

[0007] Preferably, the lower side of the locking pin is provided with a lever that passes downward through the main body of the bracket. The lever is set in a reasonable way to make use of the space under the main body of the bracket, so that the operator can drive the locking pin forward to move away from the positioning hole and allow the sliding block to slide smoothly.

[0008] Preferably, a front cover plate is installed on the front side of the main body of the bracket, and a limiting step is provided on the outer side of the locking pin. The locking pin passes through the through hole in the front cover plate and is axially limited by the limiting step. The spring is set between the front cover plate and the main body of the bracket. The front cover plate is detachable to facilitate the removal and installation of the locking pin.

[0009] Preferably, the dyeing machine robotic arm connecting plate is inserted into a slot in the middle of the upper side of the hanger body. The side wall of the hanger body is provided with screw holes that match the slot. Limiting screws for limiting the position of the dyeing machine robotic arm connecting plate are installed in the screw holes. Different models of dyeing machine robotic arm connecting plates can be replaced according to different dyeing machines. Installation and disassembly are relatively simple.

[0010] Preferably, the main body of the hanging frame is made of polymer resin material, and the connecting plate, sliding block and hook of the dyeing machine robotic arm are made of stainless steel material, which not only ensures corrosion resistance and acid and alkali resistance, but also reduces the operating load of the equipment through weight reduction design.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] With a simple structure, the distance between the two hooks can be adjusted by setting a movable sliding block. When the hooks are disassembled from the slide holder, they can be disassembled simply by moving the sliding block. The hooks will not deform. Moreover, the sliding block can switch between multiple positions through the cooperation of the locking post and the positioning hole to adapt to different specifications of slide holders. Therefore, the hanging bracket assembly of this utility model can not only solve the problem that the metal hooks of the existing slide holder brackets are prone to deformation when disassembling and assembling with the slide holder, causing the slide holder to fall off accidentally, but also adapt to different specifications of slide holders and different staining machines, and has good versatility.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] like Figure 1-5As shown, this utility model addresses the problem that existing slide holder hangers are prone to deformation of metal hooks during disassembly and assembly, leading to accidental slide holder detachment. The present invention provides the following technical solution: a self-locking staining machine hanger assembly adaptable to multiple slide holder specifications, comprising a hanger body 2. The hanger body 2 has sliding cavities 13 at both ends. Sliding blocks 5, which can extend and retract along the ends of the hanger body 2, are installed inside the sliding cavities 13. Hooks 4 for connecting to both ends of the slide holder 1 are vertically connected to the lower end of the sliding blocks 5. Locking pins 12, which can move back and forth, are installed on the sidewalls of the hanger body 2 corresponding to the sliding cavities 13. The side wall is provided with multiple positioning holes 10 that fit into the locking pin 12. When the locking pin 12 moves forward, it disengages from the positioning holes 10. The upper middle part of the main body 2 of the bracket is equipped with a dyeing machine robotic arm connecting plate 3. The end of the sliding block 5 is provided with a downward-facing recessed groove 9. The recessed groove 9 matches the auxiliary hook on the dyeing agent robotic arm. The distance between the two hooks 4 can be adjusted by setting the movable sliding block 5. When the hook 4 is disassembled from the slide holder 1, it can be disassembled by simply moving the sliding block 5. The hook 4 will not deform. Moreover, the sliding block 5 can achieve multiple switching through the cooperation of the locking pin 12 and the positioning hole 10 to adapt to different specifications of slide holders.

[0022] Specifically, the main body 2 of the bracket can be set in a long strip shape, and the sliding cavities 13 at both ends are also long strips. Their cross-sections match the cross-sections of the sliding block 5. When the sliding block 5 slides outward, the distance between the two hooks 4 increases, which can match a standard slide holder with 30 slides. When the sliding block 5 slides inward, the distance between the two hooks 4 decreases, which can match a standard slide holder with 20 slides. Whether it is a standard slide holder with 20 slides or a standard slide holder with 30 slides, a corresponding number of slide slots 11 are arranged on its inner side.

[0023] In use, the slide is inserted into the slide slot 11, the slide holder 1 is fixed to the hook 4, and the main body 2 of the bracket is fixed to the fully automatic dyeing machine. Specifically, a triangular guide hole is hollowed out on the robotic arm connecting plate 3 of the dyeing machine, which forms a clearance fit with the protruding structure of the robotic arm in the fully automatic dyeing machine to form a fixed point. At the same time, the recessed groove 9 on the lower side of the end of the sliding block 5 can be used to fix the auxiliary rising hook groove of the robotic arm in the fully automatic dyeing machine with a pin. Therefore, the robotic arm connecting plate 3 and the recessed groove 9 can be selected and used according to different fully automatic dyeing machines. That is, the bracket assembly in this embodiment can be used for the two main types of robotic arms of existing fully automatic dyeing machines, which has good versatility.

[0024] In this embodiment, as Figure 1As shown, the top of the sliding cavity 13 is open, and a cover plate 6 covering the sliding cavity 13 is provided on the upper side of the hanging body 2. A groove 7 is provided in the middle of the cover plate 6. A guide protrusion 8 is provided on the top of the sliding block 5, which is embedded in or passes through the groove 7. The guide protrusion 8 can not only guide the sliding of the sliding block 5, but also allow the operator to quickly drive the sliding block 5 to slide. The top of the guide protrusion 8 can be provided with an anti-slip structure, such as teeth, anti-slip texture, etc., so that there will be no slippage when the operator drives the guide protrusion 8 with his thumb. The length of the groove 7 matches the stroke of the sliding block 5.

[0025] In this embodiment, a spring 15 is sleeved on the outer side of the locking post 12. The spring 15 keeps the locking post 12 in the state of being engaged with the positioning hole 10 and keeps the locking post 12 in the locked position, ensuring the safety of the bracket assembly when connected to the slide holder 1. When unlocking is required, the locking post 12 needs to be pulled outward. To facilitate the pulling outward of the locking post 12, a lever 17 is provided on the lower side of the locking post 12, which passes downward through the bracket body 2. The lever 17 makes reasonable use of the space below the bracket body 2, making it convenient for the operator to drive the locking post 12 forward to disengage from the positioning hole 10, allowing the sliding block 5 to slide smoothly.

[0026] Two positioning holes 10 can be provided on the side of the sliding block 5, corresponding to either a 20-piece standard slide holder or a 30-piece standard slide holder. During operation, the technician pushes the sliding block 5 outward to its maximum stroke. At this time, the guide protrusion 8 expands to both sides simultaneously. The distance between the two rods is suitable for the installation requirements of a 30-piece standard slide holder. The locking pin 12 is precisely embedded in the positioning hole 10 of the carrier to form a rigid connection. When switching to a 20-piece slide holder, the locking pin 12 is pushed outward to disengage it from the first positioning hole 10. Then, the sliding block 5 is pushed to slide towards the axis until it enters the positioning hole 10. At this time, the distance between the rods is adapted to a smaller slide holder through a mechanical self-locking mechanism.

[0027] In this embodiment, a front cover plate 14 is installed on the front side of the hanger body 2, and a limiting step is provided on the outer side of the locking pin 12. The locking pin 12 passes through the through hole on the front cover plate 14 and is axially limited by the limiting step. The spring 15 is disposed between the front cover plate 14 and the hanger body 2. The front cover plate 14 is detachable to facilitate the disassembly and installation of the locking pin 12. The front cover plate 14 can be connected and fixed to the hanger body 2 by screws.

[0028] In this embodiment, the dyeing machine robotic arm connecting plate 3 is inserted into the slot in the middle of the upper side of the hanging frame body 2. The side wall of the hanging frame body 2 is provided with screw holes 18 that match the slot. The screw holes 18 are equipped with limiting screws to limit the position of the dyeing machine robotic arm connecting plate 3. Different models of dyeing machine robotic arm connecting plates 3 can be replaced according to different dyeing machines. The installation and disassembly are relatively simple.

[0029] In this embodiment, the main body 2 of the hanging frame is made of polymer resin material, and the connecting plate 3, sliding block 5 and hook 4 of the dyeing machine robotic arm are made of stainless steel material, which not only ensures corrosion resistance and acid and alkali resistance, but also reduces the operating load of the equipment through weight reduction design.

[0030] In summary, the technical solution adopted in this embodiment has the following technical effects:

[0031] 1. In existing technologies, disassembling the slide holder and the hanger requires direct external force to pull the metal hook. The lateral torque causes the hook to deform by 0.1-0.3 mm in a single operation, and the cumulative deformation can reach 1-2 mm after 50 operations. This results in an increased gap between the slide holder and the hook (exceeding 0.5 mm), making it very easy for the hook to fall off when the staining machine is running (vibration frequency 5-10 Hz). The solution in this embodiment uses a sliding block to move the hook horizontally to achieve disassembly. The hook only bears vertical tension (balanced with the weight of the slide holder) and has no lateral torque. After 1000 disassembly and assembly tests, the hook deformation is less than 0.02 mm, the gap is stable within 0.1 mm, and the risk of falling off is reduced to zero.

[0032] 2. Existing slide holders only accommodate a single specification (e.g., 30 slides per pack, 200mm in length). Changing specifications requires replacing the entire slide holder assembly. This embodiment utilizes the multi-positional cooperation of sliding blocks and positioning holes to precisely accommodate mainstream slide holders of 20 slides (150mm in length), 30 slides (200mm in length), and 40 slides (250mm in length): positioning holes are spaced 25mm apart along the length of the sliding block, and the clearance between the locking post and the positioning hole is ≤0.05mm, ensuring that the hook spacing error is ≤0.1mm after position switching, meeting the alignment accuracy requirements of the connecting holes at both ends of the slide holder.

[0033] 3. Existing technology requires both hands to pull the hooks on both sides during disassembly, taking 8-10 seconds per operation. Uneven force can easily cause the slide holder to tilt (angle > 5°), potentially causing staining solution to drip. The solution in this embodiment, through the cooperation of a lever and guide protrusions, allows for single-person, single-handed operation: unlocking by moving the lever (3-5mm stroke) takes only 1 second, and adjusting the spacing by pushing the guide protrusions (sliding speed 50-100mm / s) takes only 2-3 seconds. The total time for disassembly and assembly is ≤ 5 seconds, improving efficiency by over 50%. Simultaneously, the anti-slip texture of the guide protrusions (0.5mm deep diagonal grooves, 1mm spacing) prevents slippage, ensuring smooth sliding and a slide holder tilt angle < 1°, eliminating the risk of staining solution dripping.

[0034] 4. The main body of the hanging rack is made of high-molecular resin (such as ABS, model ABS-757), which has the characteristics of acid and alkali corrosion resistance (no cracking or discoloration after immersion in staining solution environment of pH2-pH12 for 30 days); the connecting plate, sliding block and hook of the staining machine robotic arm are made of 304 stainless steel (2mm thick), which has passed the salt spray test (5% NaCl solution, 35℃, 48 hours) without corrosion, ensuring a service life of ≥3 years in the humid environment of the pathology laboratory with multiple chemical reagents (the service life of existing metal hooks is usually <1 year due to the ordinary material).

[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0036] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0037] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
