Description

Technical Field

[0001] This utility model relates to the field of small and medium-sized instrument technology, specifically to a flip cover limiting device. Background Technology

[0002] Flip-cover limiting devices are a common structure in the housings of small and medium-sized instruments. They mainly use standard hinges to achieve the flipping of the cover. First, the hinge is usually installed near the edge of the instrument housing, making it easy for the hinge to be exposed and affecting the overall appearance of the instrument. When the flip cover is in the center of the instrument housing, the upper surface of the flip cover is prone to colliding with the main body of the housing after it is opened, causing wear to the paint surface of the housing and affecting the appearance. In addition, the damping effect of the flip cover is generated by the interference fit between the pin and the pin hole. After repeated use, the damping effect is easily weakened or lost. After repeated use, the damping will become smaller and it will not be able to meet the requirement of stopping at any position within the opening and closing angle range. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of the existing technology by providing a flip cover limiting device, so as to accurately control the opening and closing angle of the flip cover while avoiding bumps and knocks, and to achieve stable stopping at any opening and closing angle.

[0004] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a flip cover limiting device, including: a flip cover, a shell body, a limiting block, and a rotating component; The outer shell body has a receiving cavity for accommodating the flip cover. The flip cover is rotatably connected to the outer shell body through the rotating assembly. The rotating assembly includes a fastening rotating shaft and an elastic sealing ring sleeved on the fastening rotating shaft. The fastening rotating shaft passes through the limiting block, and when the flip cover is opened to the maximum angle, the limiting surface of the limiting block contacts the outer shell body. The flip cover is also provided with a rotating hole that rotatably engages with the fastening rotating shaft. The rotating hole is located on the side of the flip cover and at the end of the flip cover. The elastic sealing ring is used to close the rotating hole.

[0005] In some embodiments, the flap also includes a first foam, a foam base plate, and a second foam. The flap is provided with a mounting cavity for accommodating the first foam. The first foam is fixed in the mounting cavity. The foam base plate is fixed to the flap. The second foam is disposed on the foam base plate and protrudes from the bottom surface of the flap.

[0006] In some embodiments, the hardness of the first foam is less than that of the second foam.

[0007] In some embodiments, a magnetic attraction component is further included, the magnetic attraction component including a circular magnet and a magnet holder, the circular magnet being fixedly disposed on the foam base plate and partially penetrating the second foam, the magnet holder being disposed in the receiving cavity and magnetically coupled to the circular magnet.

[0008] In some embodiments, the limiting block is connected to the fastening rotating shaft by an additional fastener, the additional fastener including a screw and a set screw.

[0009] In some embodiments, a rotating shaft fixing seat is further included. The rotating shaft fixing seat is disposed on the housing body, and the fastening rotating shaft is rotatably engaged with the rotating shaft fixing seat and passes through the rotating shaft fixing seat to connect with the limiting block.

[0010] In some embodiments, the rotating hole is located on the side of the flip cover and close to the upper surface of the flip cover.

[0011] In some embodiments, the limiting surface contacts the upper surface of the housing body to limit the opening angle of the flip cover.

[0012] Furthermore, the beneficial effects of this utility model are as follows: This invention features a fastening rotating shaft with an elastic sealing ring and a limiting block. The limiting block ensures that its limiting surface contacts the outer shell when the flip cover is opened to its maximum angle, thus achieving precise control of the flip cover's opening angle and preventing excessive rotation that could cause the flip cover to collide with the outer shell. The elastic sealing ring provides adjustable damping and efficient sealing and dust prevention, ensuring smooth flip cover rotation and preventing external contaminants from entering.

[0013] Meanwhile, this utility model also includes a first foam, a foam base plate, and a second foam. The first foam, the foam base plate, and the second foam reduce the impact and noise when closing. The addition of the magnetic suction component can firmly attract the flip cover when it is closed, thus enhancing the stability of the flip cover closure. Attached Figure Description

[0017] like Figure 1 - Figure 8 As shown, this utility model provides a flip cover 1 limiting device, including: flip cover 1, outer shell body 7, limiting block 10, and rotating assembly; The outer shell body 7 has a receiving cavity 11 for accommodating the flip cover 1. The flip cover 1 is rotatably connected to the outer shell body 7 through a rotating assembly. The rotating assembly includes a fastening rotating shaft 9 and an elastic sealing ring 8 sleeved on the fastening rotating shaft 9. The fastening rotating shaft 9 passes through the limiting block 10, and when the flip cover 1 is opened to the maximum angle, the limiting surface 15 of the limiting block 10 contacts the outer shell body 7. The flip cover 1 is also provided with a rotating hole 13 that is rotatably engaged with the fastening rotating shaft 9. The rotating hole 13 is located on the side of the flip cover 1 and at the end of the flip cover 1. The elastic sealing ring 8 is used to close the rotating hole 13.

[0018] In the above structure, when the flip cover 1 of this utility model is rotated to the maximum angle, the limiting surface 15 of the limiting block 10 contacts the upper surface of the outer shell body 7, preventing the flip cover 1 from opening further and ensuring that the angle is controllable. At the same time, by setting a fastening rotating shaft 9 with an elastic sealing ring 8, and also setting a limiting block 10, the limiting block 10 can make its limiting surface 15 contact the outer shell body 7 when the flip cover 1 is opened to the maximum angle. The elastic sealing ring 8 can achieve the effect of providing adjustable damping and efficient sealing and dust prevention, ensuring that the flip cover 1 rotates smoothly and preventing external pollutants from entering.

[0019] One possible implementation includes a first foam 2, a foam base plate 4, and a second foam 5. The flip cover 1 has a mounting cavity 12 for accommodating the first foam 2. The first foam 2 is fixed in the mounting cavity 12. The foam base plate 4 is fixed to the flip cover 1. The second foam 5 is disposed on the foam base plate 4 and protrudes from the bottom surface of the flip cover 1. The hardness of the first foam 2 is less than that of the second foam 5. The back of the first foam 2 is provided with adhesive. The first foam 2 is installed inside the mounting cavity 12 of the flip cover 1. The foam base plate 4 is fixed to the flip cover 1 by four M2.5*6 countersunk screws, and the second foam 5 is adhered by adhesive. The first foam 2 is made of black sponge, and the second foam 5 is made of black silicone rubber. As shown in the figure, both the foam base plate 4 and the second foam 5 have clearance grooves. The first foam 2 passes through the foam base plate 4 and the second foam 5. This completes the installation process of the first foam 2, the foam base plate 4, and the second foam 5. In use, the outer shell 7 is installed on the instrument body. After manually opening the flip cover 1 and inserting the reagent card box, the first foam 2 contacts the reagent card box and is compressed by about 3mm, which gives the reagent card box a reverse force, which helps to place the reagent card box in place and reduces the impact and noise when closing.

[0020] One possible implementation also includes a magnetic suction assembly, which includes a circular magnet 3 and a magnet fixing seat 6. The circular magnet 3 is fixedly disposed on the foam base plate 4 and partially penetrates the second foam 5. The magnet fixing seat 6 is disposed in the receiving cavity 11 and is magnetically coupled to the circular magnet 3. Specifically, as shown in the figure, there are two sets of circular magnets 3. One set is placed in the cylindrical hole on the magnet fixing strip, and the other set is disposed on the foam base plate 4. When the flip cover 1 is closed, the attraction force of the magnet can ensure that the flip cover 1 is pressed into place, thereby enhancing the closing stability of the flip cover 1.

[0021] In one possible implementation, the limiting block 10 is connected to the fastening rotating shaft 9 via additional fasteners, including screws and set screws, and also includes a rotating shaft fixing seat 14. The rotating shaft fixing seat 14 is disposed on the housing body 7. The fastening rotating shaft 9 is rotatably engaged with the rotating shaft fixing seat 14 and passes through the rotating shaft fixing seat 14 to connect with the limiting block 10. In the above structure, one end of the fastening rotating shaft 9 is provided with a threaded structure. First, an M2.5*10 Torx socket screw and an M2.5 set screw are pre-installed on the limiting block 10. Then, the fastening rotating shaft 9 passes through the rotating shaft fixing seat 14 on the housing body 7, wherein the threaded end is threadedly connected to the rotating hole 13 on the flip cover 1. However, it is worth noting that as the connection between the fastening rotating shaft 9 and the flip cover 1 becomes more secure, the elastic deformation of the elastic sealing ring 8 on the fastening rotating shaft 9 also increases, thereby... The damping of the flip cover 1 can be adjusted, and the gap between the flip cover 1 and the side wall of the cavity 11 on the outer shell body 7 can also be adjusted. After the gap is properly adjusted, the limiting surface 15 of the limiting block 10 is brought into contact with the outer shell body 7, and the M2.5*10 Torx socket screw and M2.5 set screw pre-installed on the limiting block 10 are tightened. With the tightening of the threads, the flip cover 1, the fastening rotating shaft 9 and the limiting block 10 become a whole. When the flip cover 1 is opened, as the angle of the flip cover 1 increases, when the maximum opening angle of 120° is reached, the limiting surface 15 of the limiting block 10 first contacts the upper surface of the outer shell body 7, thereby preventing the outer surface of the flip cover 1 from colliding with the outer surface of the outer shell body 7. This achieves the effect of precisely controlling the opening angle of the flip cover 1 and preventing the collision between the flip cover 1 and the outer shell body 7 caused by excessive rotation.

[0022] In one possible implementation, the rotating hole 13 is located on the side of the flip cover 1 and close to the upper surface of the flip cover 1, as shown in the figure. More specifically, the center of the rotating hole 13 is 5.5 mm away from the upper surface of the flip cover 1 and 10 mm away from the side.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
