Description

Technical Field

[0001] This utility model relates to the technical field of thin tube clamping devices, and in particular to a thin tube clamping device. Background Technology

[0002] In modern animal husbandry, cattle breeding has become an important way to improve the production performance of cattle herds and improve breeds. Artificial insemination is a key step in cattle breeding, which usually requires the use of thin-diameter insemination tubes or frozen semen aspiration tubes to deliver the collected and processed semen into the cow's body. Because insemination tubes are mostly thin, long, smooth, transparent tubes with small diameters and are fragile, a high degree of stability and cleanliness is required during the operation.

[0003] Existing clamps mostly use metal structures and rely on rigid clamping to fix thin tubes. These clamps come into direct contact with the thin tubes during use, and the tubes are easily damaged due to their high surface hardness. In addition, they need to be disinfected with high intensity after each operation to prevent cross-contamination. This not only increases the complexity of the operation process, but also makes it difficult to achieve continuous and high-frequency clamping operations, resulting in low overall efficiency. Utility Model Content

[0004] Therefore, it is necessary to provide a clamping device for thin tubes, which addresses the problems that existing clamps are mostly metal structures that rely on rigid clamping to fix thin tubes, which can easily cause damage to the tube body. Furthermore, they require high-intensity disinfection after each use, which increases the complexity of operation, makes it difficult to achieve continuous high-frequency operation, and results in low overall efficiency.

[0005] A clamping device for thin tubes includes: a clamp; a protective replacement mechanism, wherein a telescopic protective replacement mechanism for quickly replacing the contact part after clamping is disposed on one side of the clamp; wherein the protective replacement mechanism includes two protective sleeves fixedly installed on one side of the clamp, each of the two protective sleeves is provided with a contact component, and a reset component is provided inside the clamp.

[0006] The contact assembly includes a fixing groove formed on one side of two adjacent protective sleeves, a contact pad is provided inside the fixing groove, and a clamping pad is fixedly installed inside the contact pad.

[0007] The inner wall of the fixing groove is fixedly connected with multiple locking strips. The contact pad has multiple locking slots on the side near the fixing groove. The multiple locking slots engage with adjacent locking strips. The protective sleeve has a positioning groove on one side. The protective sleeve engages with one side of the clamp through the positioning groove.

[0008] The contact pad is rectangular, and multiple friction strips are fixedly connected to the side of the contact pad away from the fixing groove.

[0009] All of the friction strips are arranged horizontally, and all of the friction strips are equidistantly distributed.

[0010] A sealing ring is fixedly installed on the outer side of the contact pad, and the sealing ring is sealed and snapped into the inner wall of the fixing groove.

[0011] The reset assembly includes a spring disposed inside the clamp, both ends of which are fixedly connected to the inner wall of the clamp.

[0012] The spring is provided with a protective sleeve on its outer side, and both sides of the protective sleeve are fixedly connected to the inner wall of the clamp.

[0013] Beneficial effects

[0014] 1. Each time the clamp picks up a thin tube, the contact components can be quickly replaced with brand new contact parts, avoiding the risk of cross-contamination caused by repeated use of traditional metal clamps, and significantly improving the cleanliness and biosafety of the operation. The reset component can automatically reset after the clamp completes the gripping action, restoring the protective sleeve to its initial state, facilitating the next replacement of the contact components, thereby ensuring the continuity and efficiency of the operation;

[0015] 2. When the clamp is subjected to external force while gripping the thin tube, the spring can be compressed to store energy; after the external force is released, the spring releases its elastic potential energy and quickly resets the clamp to its initial position, which not only ensures that the clamp always has the ability to quickly reset during multiple gripping operations.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-5 This invention describes a clamping device for thin tubes.

[0026] In one embodiment, a clamping device for a thin tube includes: a clamp 100; a protective replacement mechanism 200, wherein the telescopic protective replacement mechanism 200 for quickly replacing the contact part after clamping is disposed on one side of the clamp 100; wherein the protective replacement mechanism 200 includes two protective sleeves 210 fixedly installed on one side of the clamp 100, each of the two protective sleeves 210 having a contact component 220 on one side, and a reset component 230 being disposed inside the clamp 100.

[0027] In this embodiment, the contact component 220 can be quickly replaced with a completely new contact part each time the clamp 100 grips the thin tube, avoiding the risk of cross-contamination caused by repeated use of traditional metal clamps 100, and significantly improving the cleanliness and biosafety of the operation. The reset component 230 can automatically reset after the clamp 100 completes the gripping action, restoring the protective sleeve 210 to its initial state, facilitating the next replacement of the contact component 220, thereby ensuring the continuity and efficiency of the operation;

[0028] It should be noted that the thin tube clamping device typically includes a clamping fixture 100 body for clamping and an elastic element for driving the clamping action to achieve the clamping and releasing function of the thin tube. The contact component 220 only performs a quick replacement of the clamping part after the clamping action is completed and does not participate in the clamping movement of the clamping fixture 100 body, so it will not affect the normal clamping process of the clamping device. The reset component 230 only provides a reset force after the clamping fixture 100 completes the clamping, so that the protective replacement mechanism 200 returns to its initial state. Its function is independent of the clamping function of the clamping fixture 100, so it will not interfere with the stability and accuracy of the thin tube clamping.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, the contact assembly 220 includes a fixing groove 221 formed on one side of the two protective sleeves 210. A contact pad 222 is provided inside the fixing groove 221, and a clamping pad 226 is fixedly installed inside the contact pad 222.

[0030] In this embodiment, when the clamp 100 grips the thin tube, it can flexibly fit and hold the outer wall of the thin tube through the clamping pad 226. The contact pad 222 can play a buffering role to avoid damage or breakage of the thin tube due to rigid contact. The clamping pad 226 is made of phase change material, which can absorb or release heat according to temperature changes during the clamping of breeding cattle, and maintain a relatively stable temperature of the contact surface with the thin tube, avoiding condensation or sliding of the tube wall due to sudden temperature changes. Since the contact pad 222 can be detachably installed in the fixing groove 221, it can be quickly replaced when its surface is contaminated or worn, ensuring that the clamp 100 still has a stable clamping effect and good cleanliness in high-frequency operation.

[0031] Multiple locking strips 223 are fixedly connected to the inner wall of the fixing groove 221. Multiple locking slots 224 are opened on the side of the contact pad 222 near the fixing groove 221. The multiple locking slots 224 are engaged with the adjacent locking strips 223. A positioning groove 227 is opened on one side of the protective sleeve 210. The protective sleeve 210 is engaged with one side of the clamp 100 through the positioning groove 227.

[0032] In this embodiment, the contact pad 222 can be securely installed in the fixing groove 221 by snap-fit, which not only ensures the stability during the clamping process, but also facilitates quick replacement after wear or contamination. The positioning groove 227 on one side of the protective sleeve 210 is snapped into the clamp 100, realizing the reliable positioning and fixation of the protective sleeve 210, avoiding loosening or displacement during the clamping of the thin tube. In addition, the protective sleeve 210 also has a quick replacement function, so that the clamp 100 can be flexibly switched according to different usage needs or disinfection requirements.

[0033] The contact pad 222 is rectangular, and multiple friction strips 225 are fixedly connected to the side of the contact pad 222 away from the fixing groove 221.

[0034] In this embodiment, the contact pad 222 adopts a rectangular structure design, which enables it to form a stable force-bearing support surface within the fixing groove 221, ensuring uniform force during clamping. When clamping the thin tube, the friction strip 225 effectively increases the friction between the friction strip and the tube wall, preventing slippage due to a smooth tube surface or the presence of condensation, thereby improving the stability and reliability of clamping. Simultaneously, the friction strip 225 can also disperse stress to a certain extent, reducing localized pressure on the outer wall of the thin tube and minimizing the risk of breakage.

[0035] Multiple friction strips 225 are arranged horizontally, and the multiple friction strips 225 are equidistantly distributed.

[0036] In this embodiment, the contact pad 222 can form a uniform frictional force distribution when clamping the thin tube, effectively avoiding damage to the thin tube caused by excessive local force. The transverse friction strip 225 can provide a stable limiting effect in the axial direction of the thin tube, preventing the thin tube from slipping or rotating during clamping, thereby ensuring the stability and accuracy of clamping.

[0037] A sealing ring 228 is fixedly installed on the outer side of the contact pad 222, and the sealing ring 228 is sealed and engaged with the inner wall of the fixing groove 221.

[0038] In this embodiment, the sealing ring 228 can form a sealing engagement with the inner wall when it is assembled into the fixing groove 221. This not only ensures the stability of the contact pad 222 during the clamping process and prevents it from loosening or falling off, but also effectively blocks external dust, liquid or impurities from entering the fixing groove 221, thus avoiding the degradation of the performance of the contact components due to contamination.

[0039] like Figure 2 , Figure 3 and Figure 5 As shown, the reset assembly 230 includes a spring 231 disposed inside the clamp 100, and both ends of the spring 231 are fixedly connected to the inner wall of the clamp 100.

[0040] In this embodiment, when the clamp 100 is subjected to an external force while gripping the thin tube, the spring 231 can be compressed to store energy; after the external force is released, the spring 231 releases its elastic potential energy and quickly resets the clamp 100 to its initial position, which not only ensures that the clamp 100 always has the ability to quickly reset during multiple gripping operations.

[0041] A protective sleeve 232 is provided on the outer side of the spring 231, and both sides of the protective sleeve 232 are fixedly connected to the inner wall of the clamp 100.

[0042] In this embodiment, the protective sleeve 232 enables the spring 231 to always move within a limited trajectory during compression and extension, avoiding jamming or deformation caused by deviation or external force interference. The protective sleeve 232 can also effectively block external dust, liquid or impurities from entering the working area of ​​the spring 231, reducing the impact of corrosion and pollution on elastic performance, thereby extending the service life of the spring 231.

[0043] Working Principle: First, the thin tube is placed within the clamping area of ​​the clamp 100. Two protective sleeves 210 flexibly clamp the thin tube via contact components 220. The rectangular support surface of the contact pad 222 ensures uniform clamping force, preventing damage to the tube wall due to single-point force. The friction strips 225 on its outer side adhere to the outer wall of the thin tube, providing sufficient friction to prevent slippage caused by smooth surfaces or condensation. The friction strips 225 are laterally and equidistantly distributed, ensuring uniform clamping force along the thin tube's axis, thus guaranteeing a stable and reliable clamping process. After the clamp 100 completes one clamping operation, the spring 231 in the reset component 230 automatically releases its stored energy when the external force is removed, restoring the protective sleeve 210 to its initial position. The protective replacement mechanism 200 is then in a replaceable state. At this time, the contact component 220 can be quickly disassembled and replaced with brand-new contact pads 222 and clamping pads 226, effectively avoiding the risk of cross-contamination from repeated use and ensuring the cleanliness and biosafety of the clamp 100 during high-frequency operations. The sealing ring 228 forms a sealed engagement with the inner wall of the fixing groove 221, preventing external impurities from entering the fixing groove 221 and maintaining the long-term stability and reliability of the contact components. Throughout the clamping process, the clamping pad 226, as a phase change material component, can regulate the temperature of the contact area with the thin tube during operation, avoiding condensation or slippage on the surface of the thin tube caused by temperature differences, thereby further improving clamping stability. The protective sleeve 232 on the outside of the spring 231 ensures the smooth operation of the spring 231 during the reset process and prevents dust and impurities from entering, improving the reliability and lifespan of the reset action.
