Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of centrifuge accessories, and in particular to a centrifuge door cover limiting structure. Background Technology
[0002] Centrifuges can use centrifugal force to separate substances of different densities, particle sizes, or phases in a mixture. The core logic is to accelerate and amplify the difference in gravity through rotation, allowing heavier or denser substances in the mixture to move faster to the outside of the rotation center, thus separating them from lighter substances. They are mainly used in industrial production, medical testing, and scientific research.
[0003] In the existing technology, centrifuge doors are generally limited by gas springs after being opened. However, for small centrifuges, due to their compact internal structure, there is often not enough space inside the metal shell to install gas springs, so they often lack a limiting structure. At the same time, installing gas springs would also lead to relatively high production costs.
[0004] Therefore, it is necessary to invent a centrifuge door cover limiting structure to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a door cover limiting structure for centrifuges, which has low operating costs, does not occupy the internal space of the metal shell, and the limiting component itself can be produced by punching and bending processes, which reduces the production difficulty and eliminates the need for additional screw holes or bolts on the metal shell and door cover. This ensures the limiting function while further simplifying the structure, reducing production difficulty and cost, and solving the problem mentioned in the background art that for small centrifuges, due to their compact internal structure, there is often not enough space inside the metal shell to install a gas spring, thus often lacking a limiting structure. At the same time, installing a gas spring would also lead to relatively high production costs.
[0006] According to one aspect of this disclosure, the following technical solution is provided: a centrifuge door cover limiting structure, comprising:
[0007] A centrifuge housing assembly, which provides a mounting mechanism for a movable connection assembly;
[0008] Two sets of movable connection assemblies, the two sets of movable connection assemblies being used for movable connection of the centrifuge housing assembly; and
[0009] The limiting component includes a vertical fitting part that fits into two hinges, an inclined limiting part that is fixedly provided at the top of the vertical fitting part, the vertical fitting part and the inclined limiting part are integrally formed, a supporting plane is provided at the top of the inclined limiting part, an avoidance groove is provided on the front of the vertical fitting part, and the vertical fitting part is fixed by two adjacent mounting bolts.
[0010] According to at least one embodiment of the centrifuge door cover limiting structure of the present disclosure, the centrifuge housing assembly includes a metal housing with a top opening, the top of which is fitted with a door cover.
[0011] According to at least one embodiment of the centrifuge door cover limiting structure of the present disclosure, a plurality of heat dissipation openings are provided at the bottom and middle of the back of the metal housing, and door covers are fixedly provided at the four corners of the bottom of the metal housing.
[0012] According to at least one embodiment of the centrifuge door cover limiting structure of the present disclosure, any group of the movable connecting components includes four mounting screw holes respectively opened on the top of the back of the metal housing and the top of the back of the door cover, and the four mounting screw holes are distributed in a rectangular manner.
[0013] According to at least one embodiment of the centrifuge door cover limiting structure of the present disclosure, the movable connection assembly further includes a hinge that fits against the metal housing and the back of the door cover, and four clearance holes are provided at the four corners of the back of the hinge.
[0014] According to at least one embodiment of the centrifuge door cover limiting structure of the present disclosure, each of the four clearance holes is provided with a mounting bolt extending to the inside of an adjacent mounting screw hole, and the mounting bolt is screwed to the adjacent clearance hole.
[0015] According to at least one embodiment of the centrifuge door cover limiting structure of the present disclosure, two adjacent mounting bolts in the lower part of the two sets of movable connecting assemblies pass through the vertical fitting part and are pressed against the side of the vertical fitting part.
[0016] The technical effects and advantages of this utility model are as follows:
[0017] In this invention, when the door cover is opened by the hinge, the upright door cover can be supported by the support plane at the top of the inclined limiting part, thereby limiting the door cover and preventing it from overturning backward, which would increase the difficulty of subsequent reset. The cost of use is low, and it does not occupy the internal space of the metal shell. At the same time, the limiting component itself can be produced by punching and bending processes, which is easy to produce and does not require additional screw holes or additional bolts on the metal shell and door cover. This ensures the limiting function while further simplifying the structure and reducing the production difficulty and cost. Attached Figure Description
[0018] The accompanying drawings illustrate exemplary embodiments of the present disclosure and, together with the description thereof, serve to explain the principles of the present disclosure. These drawings are included to provide a further understanding of the present disclosure and are incorporated in and constitute a part of this specification.

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.
[0027] Figure 1 This is a schematic diagram of the overall structure of a centrifuge door cover limiting structure according to one embodiment of the present disclosure.
[0028] Figure 2 This is a partial structural diagram of the centrifuge housing assembly 1 and the movable connection assembly 2 of a centrifuge door cover limiting structure according to one embodiment of the present disclosure.
[0029] Figure 3 This is a partial structural diagram of the movable connection assembly 2 and the limiting assembly 3 of the centrifuge door cover limiting structure according to one embodiment of the present disclosure.
[0030] like Figures 1-3 As shown, the centrifuge door cover limiting structure disclosed herein may include: centrifuge housing assembly 1, two sets of movable connection assemblies 2, and limiting assembly 3, etc.
[0031] like Figure 2 As shown in this disclosure, the centrifuge housing assembly 1 includes a metal housing 11 with a top opening, a door cover 12 attached to the top of the metal housing 11, multiple heat dissipation openings 13 at the bottom and middle of the back of the metal housing 11, and support columns 14 fixedly installed at the four corners of the bottom of the metal housing 11.
[0032] Thus, the door cover 12 is used to cover the top opening of the metal housing 11, the heat dissipation opening 13 is used to assist the electrical components installed inside the metal housing 11 in heat dissipation, and the support column 14 provides effective support for the metal housing 11. All of these are conventional technologies in the field.
[0033] like Figure 2 and Figure 3 As shown, in a preferred embodiment, each set of movable connecting components 2 includes four mounting screw holes 21 respectively opened on the top back of the metal housing 11 and the top back of the door cover 12. The four mounting screw holes 21 are rectangularly distributed. The movable connecting component 2 also includes a hinge 22 that fits against the back of the metal housing 11 and the door cover 12. Four clearance holes 23 are opened at the four corners of the back of the hinge 22. Mounting bolts 24 extending to the inside of the adjacent mounting screw holes 21 are passed through the inner side of each of the four clearance holes 23. The mounting bolts 24 are screwed into the adjacent clearance holes 23. The two adjacent mounting bolts 24 at the bottom of the two sets of movable connecting components 2 pass through the vertical fitting part 31 and are pressed against the side of the vertical fitting part 31.
[0034] Thus, by using four mounting bolts 24 through four mounting screw holes 21 to fix the hinge 22 to the back of the metal housing 11 and the door cover 12, the door cover 12 can be rotated on the top of the metal housing 11 through the hinge 22 to achieve opening and closing, which is a conventional technology in the field.
[0035] like Figure 3As shown in this disclosure, the limiting component 3 includes a vertical fitting part 31 that fits into two hinges 22. An inclined limiting part 32 is fixedly provided at the top of the vertical fitting part 31. The vertical fitting part 31 and the inclined limiting part 32 are integrally formed. A supporting plane 33 is provided at the top of the inclined limiting part 32. An avoidance groove 34 is provided on the front of the vertical fitting part 31. The avoidance groove 34 allows the mounting bolts 24 to pass through. At the same time, due to the wide design of the avoidance groove 34, it can reduce the difficulty of matching with the avoidance holes 23 on the two hinges 22, thereby further reducing the installation difficulty. The vertical fitting part 31 is fixed by two adjacent mounting bolts 24.
[0036] Therefore, when the door cover 12 is opened by the hinge 22, the upright door cover 12 can be supported by the support plane 33 at the top of the inclined limiting part 32, thereby limiting the door cover 12 and preventing it from over-flipping backward, which would increase the difficulty of subsequent reset. The cost of use is low and it does not occupy the internal space of the metal shell 11. At the same time, the limiting component 3 itself can be produced by punching and bending processes, which is easy to produce and does not require additional screw holes or additional bolts to be made on the metal shell 11 and the door cover 12. This ensures the limiting function while further simplifying the structure and reducing the production difficulty and production cost.
[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.
[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
