Description

Technical Field

[0001] This utility model relates to the field of quality testing equipment technology, and in particular to an egg freshness testing device. Background Technology

[0002] With the food industry's increasingly stringent requirements for egg quality control, egg freshness testing devices are widely used in production, processing, logistics, warehousing, and retail. These devices accurately collect the physical or chemical characteristics of eggs (especially yolks) and, combined with a detection module and display unit, rapidly present freshness data, providing users with a basis for judging egg quality. In actual use, the support structure (such as a tray) used to hold egg samples needs to frequently move in and out of the device's outer shell to replace samples. The opening, resetting, and fixing stability of the support structure directly affects the efficiency of the testing operation and the long-term lifespan of the device. Therefore, optimizing the transmission and locking mechanisms of the support structure has become one of the key directions for improving the practicality of egg freshness testing devices.

[0003] Currently, most commercially available egg freshness testing devices employ a linear slide rail combined with a manually pluggable locking mechanism for opening and resetting the sample-bearing structure. The device housing contains a fixed slide rail, and the sample-bearing push-pull component slides along the slide rail. The locking mechanism typically consists of a pin and a positioning hole. To open the device, the user manually pulls out the pin to release the lock, then manually pulls the push-pull component along the slide rail. After placing the sample, the user pushes the push-pull component back to its original position. Once the positioning hole aligns with the pin, the user manually inserts the pin to lock the device in place. To reduce pushing and pulling resistance, some devices add a lubricating coating to the contact area between the slide rail and the push-pull component, or incorporate a simple spring structure at the end of the push-pull component to assist in resetting its position.

[0004] Because it relies on manually inserting and removing the pin to unlock and manually pulling the push-pull component to open, it not only requires the user to complete multiple steps, increasing the complexity and difficulty of operation, but also, during the reset process of the push-pull component, it is only fixed by the rigid cooperation between the pin and the positioning hole, lacking an effective buffer structure. This causes the push-pull component to easily collide with the inner wall of the outer shell or the locking component when it is reset. After long-term use, it is easy to cause wear and deformation of the components, affecting the service life of the device. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an egg freshness detection device, which aims to improve the problem of high operational complexity caused by the need for manual pulling of the sample carrying structure in existing egg freshness detection devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an egg freshness detection device, comprising a baffle, wherein a first fixing component is provided inside the baffle, a push-pull plate is fixedly connected to one side of the outer wall of the baffle, and a symmetrical second fixing component is provided inside the push-pull plate; The first fixing component includes a first connecting block, the outer wall of which is disposed inside the baffle. A protrusion is fixedly connected to the outer wall of the first connecting block, a rotating shaft is fixedly connected to the inner wall of the protrusion, a fixing ring is rotatably connected to the inner wall of the rotating shaft, and both ends of the fixing ring are fixedly connected to the inner wall of the baffle. A second connecting block is fixedly connected to the outer wall of the rotating shaft, an arc-shaped buckle is fixedly connected to the outer wall of the second connecting block, a housing is slidably connected to the outer wall of the arc-shaped buckle, a first spring is fixedly connected to the lower surface of the arc-shaped buckle, a bearing plate is fixedly connected to one end of the first spring, and the other end of the first spring is fixedly connected to the lower surface of the arc-shaped buckle. Two fixing seats are fixedly connected to the outer wall of the push-pull plate, a second spring is fixedly connected to one end of each of the two fixing seats, the other ends of the two second springs are fixedly connected to the inner wall of a housing, and one end of each second spring is fixedly connected to one end of a fixing seat. Two sliding grooves are formed inside the housing.

[0007] Furthermore, the second fixing component includes a fixing pin, which is disposed inside the push-pull plate. A button is slidably connected inside the fixing pin. A wedge-shaped guide rod is fixedly connected to the lower surface of the button. A spring is sleeved on the outer wall of the wedge-shaped guide rod. One end of the spring is fixedly connected to the lower surface of the button, and the other end of the spring is fixedly connected to the inner wall of the push-pull plate. The outer wall of the wedge-shaped guide rod is provided with symmetrical ball bearings. A tray is fixedly connected to the outer wall of the fixing pin.

[0008] Furthermore, the outer walls of both fixed seats are slidably connected to the inner wall of the slide groove, and the outer walls of both fixed seats are slidably connected to the inner wall of the outer shell.

[0009] Furthermore, a controller is provided on one side of the outer wall of the housing, and a display screen is provided inside the housing.

[0010] Furthermore, a slot is provided inside the outer shell, and the outer wall of the arc-shaped buckle is slidably connected to the slot inside the outer shell.

[0011] Furthermore, the tray has an egg yolk groove inside.

[0012] Furthermore, the inner wall of the bearing plate is fixedly connected to the outer wall of the baffle.

[0013] Furthermore, the push-pull plate has a slot inside, and the outer walls of the two balls are slidably connected to the slot inside the push-pull plate, and the outer walls of the two balls are slidably connected to the inner wall of the fixing pin.

[0014] This utility model has the following beneficial effects: 1. In this utility model, rotating the upward protrusion causes the connecting block one and the rotating shaft to rotate synchronously along the fixed ring, which in turn causes the connecting block two to move the arc-shaped buckle downward. During this process, the arc-shaped buckle cooperates with the spring one, squeezing the spring one to deform and accumulate elastic force. After the arc-shaped buckle disengages from the slot inside the outer shell, the locking state is quickly released. The elastic force accumulated by the spring two can push the connecting block one and further drive the push-pull plate out along the slide groove. The entire opening process does not require complicated tools and can be completed by simply rotating the protrusion, simplifying the operation steps and reducing the difficulty of use for users. The spring two can buffer the impact force when the baffle is reset, avoiding damage to parts due to hard collisions and extending the service life of the device.

[0015] 2. In this utility model, when installing the tray, align the fixing pin with the push-pull plate, press the button to move the wedge-shaped guide rod downward. After the wedge-shaped guide rod moves downward, it provides space for the ball bearing to move, allowing it to disengage from the slot in the fixing pin. At this time, the fixing pin can be smoothly brought into the push-pull plate. After releasing the button, the elastic force of the spring pushes the wedge-shaped guide rod to reset, and the ball bearing re-engages between the slot in the push-pull plate and the fixing pin, realizing the rapid fixing of the tray. This can quickly complete the tray preparation work before the eggs are broken, effectively preventing the tray from loosening or shifting during the detection process due to slight vibration of the device or external force when the yolk is placed. It ensures that the yolk is always in the detection area within the yolk groove, avoiding inaccurate detection results due to tray displacement, and also facilitating the cleaning and replacement of the tray.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-6 An embodiment of this utility model is provided: an egg freshness detection device, including a baffle 2, a first fixing component is provided inside the baffle 2, a push-pull plate 13 is fixedly connected to one side of the outer wall of the baffle 2, and a symmetrical second fixing component is provided inside the push-pull plate 13. The first fixing component includes a connecting block 8, the outer wall of which is located inside the baffle 2. A protrusion 3 is fixedly connected to the outer wall of the connecting block 8. A rotating shaft 12 is fixedly connected to the inner wall of the protrusion 3. A fixing ring 9 is rotatably connected to the inner wall of the rotating shaft 12. Both ends of the fixing ring 9 are fixedly connected to the inner wall of the baffle 2. A connecting block 10 is fixedly connected to the outer wall of the rotating shaft 12. An arc-shaped buckle 11 is fixedly connected to the outer wall of the connecting block 10. A housing 1 that provides installation space for all internal components is slidably connected to the outer wall of the arc-shaped buckle 11, while protecting the internal detection module and mechanical structure and preventing external interference. A spring 7 is fixedly connected to the lower surface of the arc-shaped buckle 11. One end of the spring 7 is fixedly connected to a bearing plate 6, and the other end of the spring 7 is fixedly connected to the arc-shaped buckle. On the lower surface of the push-pull plate 13, two fixed seats 14 are fixedly connected to the outer wall. One end of each fixed seat 14 is fixedly connected to a spring 15. The other end of each spring 15 is fixedly connected to the inner wall of a housing 1. One end of each spring 15 is fixedly connected to one end of the fixed seat 14. After the baffle 2 is released from the housing 1, the spring 15 rebounds due to the accumulated elastic force. The fixed seat 14 transmits the elastic force of the spring 15 to the push-pull plate 13, causing the push-pull plate 13 to pop out of the housing 1. At the same time, it cooperates with the slide groove 16 to realize the directional sliding of the push-pull plate 13. Two slide grooves 16 are opened inside the housing 1. The slide grooves 16 limit the pop-out trajectory of the fixed seat 14 and the push-pull plate 13 to ensure that the push-pull plate 13 moves smoothly and steadily in and out of the housing 1.

[0020] Specifically, rotating the protrusion 3 upwards causes the connecting block 8 and the rotating shaft 12 to move synchronously along the fixing ring 9, causing the connecting block 10 to move the arc-shaped buckle 11 downwards. The arc-shaped buckle 11 cooperates with the bearing plate 6, squeezing the spring 7 to deform and accumulate elastic force. When the arc-shaped buckle 11 disengages from the slot of the outer shell 1, the lock is released. The elastic force generated by the deformation of the spring 15 pushes the fixing seat 14 forward. The fixing seat 14 causes the push-pull plate 13 to pop out along the slide groove 16, preparing for the subsequent installation of the tray 17 and egg inspection.

[0021] Reference Figures 1-6 The second fixing component includes a fixing pin 20, which is located inside the push-pull plate 13. A button 19, providing a point of force for the operator, is slidably connected inside the fixing pin 20. A wedge-shaped guide rod 21 is fixedly connected to the lower surface of the button 19. Pressing the button 19 causes the wedge-shaped guide rod 21 to move downwards. A spring 22 is sleeved on the outer wall of the wedge-shaped guide rod 21. One end of the spring 22 is fixedly connected to the lower surface of the button 19, providing power for the button 19 and the wedge-shaped guide rod 21 to reset. The other end of the spring 22 is fixedly connected to the inner wall of the push-pull plate 13. Symmetrical ball bearings 23 are provided on the outer wall of the wedge-shaped guide rod 21. The downward movement of the wedge-shaped guide rod 21 pushes the ball bearings 23 out of the slots in the push-pull plate 13. A tray 17 is fixedly connected to the outer wall of the fixing pin 20. The outer walls of both fixing seats 14 are slidably connected to the inner wall of the slide groove 16. A controller 5 is installed on one side of the outer wall of the outer shell 1, and a display screen 4 is installed inside the outer shell 1. A slot is opened inside the outer shell 1, and the outer wall of the arc-shaped buckle 11 is slidably connected to the slot inside the outer shell 1. A yolk groove 18 is opened inside the tray 17, which limits the placement of the yolk and prevents the yolk from flowing, ensuring that the detection module can accurately collect egg liquid data. The inner wall of the support plate 6 is fixedly connected to the outer wall of the baffle 2. A slot is opened inside the push-pull plate 13, and the outer walls of the two balls 23 are slidably connected to the slots inside the push-pull plate 13. After the wedge-shaped guide rod 21 is reset, the wedge-shaped guide rod 21 pushes the balls 23 into the slots inside the push-pull plate 13, which can lock with the slots inside the push-pull plate 13 to prevent the tray 17 from radially shifting during movement and to ensure that the yolk is always in the detection area. The outer walls of the two balls 23 are slidably connected to the inner wall of the fixing pin 20.

[0022] Specifically, pressing button 19 causes the wedge-shaped guide rod 21 to move downwards. Spring 3 22 is compressed and accumulates reset elasticity. After the wedge-shaped guide rod 21 moves downwards, it provides space for the ball 23 to move, allowing it to disengage from the inner groove of the fixing pin 20 and move to the recess of the wedge-shaped guide rod 21. The fixing pin 20 is aligned with the push-pull plate 13. When button 19 is released, spring 3 22 releases its elasticity, causing the wedge-shaped guide rod 21 to reset, so that the ball 23 locks with the push-pull plate 13. Finally, the tray 17 is installed on the push-pull plate 13, preventing the tray 17 from shifting during the testing process.

[0023] Working principle: When the device is needed, the baffle 2 should be popped out first, and the protrusion 3 should be rotated upward. The protrusion 3 drives the connecting block 8 and the rotating shaft 12 to move in the same direction along the fixed ring 9. Since the rotating shaft 12 is fixedly connected to the connecting block 10, the connecting block 10 drives the arc-shaped buckle 11 to move downward, cooperate with the bearing plate 6, and squeeze the spring 7 to deform it and accumulate elastic force. When the arc-shaped buckle 11 is disengaged from the slot inside the outer shell 1, the locking state is released. The elastic force generated by the compression deformation of the spring 15 pushes the fixed seat 14 forward. The fixed seat 14 further drives the push-pull plate 13 to pop out along the slide groove 16.

[0024] Next, install button 19 on push-pull plate 13. Since push-pull plate 13 is fixedly connected to fixing pin 20, press button 19. Button 19 drives wedge guide rod 21 to move down. Spring 3 22 is squeezed by fixing pin 20, accumulating elastic force for subsequent reset. The downward movement of wedge guide rod 21 provides space for ball 23 to move out of the slot in fixing pin 20 and move to the recess of wedge guide rod 21. Then, align fixing pin 20 with push-pull plate 13 and drive fixing component into push-pull plate 13. Release button 19. The elastic force accumulated by spring 3 22 drives wedge guide rod 21 to reset, so that ball 23 re-locks with spring 3 22 and push-pull plate 13. Finally, install tray 17 on push-pull plate 13. Then, break the egg and place it in yolk groove 18. Push baffle 2 to push yolk groove 18 into the shell 1. Adjust controller 5 and observe the test results on display screen 4.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
