Description

Technical Field

[0001] This invention relates to the field of equipment protection technology, and in particular to a connector and outer cover suitable for use with an outer cover. Background Technology

[0002] Desktop manufacturing equipment typically refers to devices capable of 3D printing, laser processing, and CNC machining. They are usually small and lightweight, suitable for indoor use in homes, and close to people. 3D printing requires heat preservation, and the molten material releases odors; laser processing generates light pollution, causing irreversible damage to the eyes; CNC machining produces dust and generates prolonged noise, causing significant pollution to the indoor environment. Therefore, desktop equipment needs protective structures to reduce environmental pollution during operation.

[0003] Most existing desktop devices use an integrated protective structure, which requires the manufacture of large molds to create the integrated shell, resulting in a long project manufacturing cycle. When repairing the equipment, it is difficult to return it to the factory for repair or for the user to disassemble and repair it themselves. Some devices have an outer cover design that separates the equipment and the protective structure, which has problems with difficult assembly and long assembly time. Summary of the Invention

[0004] The purpose of this invention is to provide a connector and outer cover suitable for outer covers, so as to solve the problems of long manufacturing cycle and difficult maintenance and assembly of existing outer covers.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] This invention first provides a connector suitable for an outer cover, comprising:

Multiple bolts can pass through the first connecting hole and the second connecting hole to thread the beam and the column.

[0010] Optionally, the end face opposite to the first opening is provided with a groove, and the second connecting hole is provided at the bottom of the groove, the groove depth being not less than the head thickness of the bolt.

[0011] Optionally, the outer and inner walls of the column mounting surface are parallel to each other and respectively connect to the two beam mounting surfaces.

[0014] The present invention also provides an outer cover, including beams, columns, a top plate, and surrounding panels. A plurality of the surrounding panels are arranged circumferentially around the top plate and form a second opening opposite to the top plate to cover a desktop device. A plurality of beams are disposed between the interconnected top plate and the surrounding panels, and a plurality of columns are disposed between two interconnected surrounding panels. The outer cover of the present invention also includes the aforementioned connectors suitable for the outer cover. Two beams and one column are connected by the connectors suitable for the outer cover to form a corner assembly, the corner assembly being located at the top corner of the outer cover.

[0015] Optionally, the beam includes a top beam and a bottom beam, both of which include a central body. The central body has a plurality of first clamping slots arranged circumferentially along the long axis of the central body and with the slotting direction perpendicular to the side of the central body. The top plate and the surrounding plate can be inserted into the first clamping slots at corresponding positions.

[0016] Optionally, at least one light strip groove is provided on the circumferential edge of the central body of the top beam. The groove is opened along the diagonal direction of the central body, and the light strip can be inserted into the light strip groove with the light-emitting surface of the light strip facing away from the central body.

[0017] Optionally, the cross-sectional shape of the column is the same as the shape of the column mounting surface of the connector suitable for the outer cover. The column includes a hollow main body and two columns symmetrically arranged at both ends of the hollow main body. The two columns are provided with two second clamping grooves on their two sides away from the hollow main body. The opening directions of the two second clamping grooves are perpendicular to each other. The two sides of the enclosure can be inserted into the second clamping grooves of the two adjacent columns respectively.

[0018] Optionally, the ends of the central body and the column are respectively provided with axial threaded holes, and bolts can be screwed into the threaded holes.

Therefore, this invention enables the assembly and manufacturing of outer casings suitable for desktop devices through the connector, resulting in a short manufacturing cycle, easy assembly and disassembly, and improved efficiency in assembly and maintenance.

[0025] The outer cover of the present invention, by employing connectors suitable for the outer cover, enables the beams and columns to be detachably assembled. The top plate and the surrounding plate are respectively inserted into the corresponding beams and columns, which facilitates disassembly and assembly, shortens the time in the manufacturing and maintenance process, simplifies the assembly process, and improves disassembly and assembly efficiency.

[0044] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0045] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0048] like Figures 1-3 As shown, the present invention first provides a connector suitable for an outer cover, hereinafter referred to as connector 1. Through connector 1, beam 2 and column 3 can be assembled to form a corner component. Multiple corner components can be assembled into an outer cover suitable for desktop equipment (hereinafter referred to as outer cover). It is suitable for an outer cover with a polygonal frame structure, which facilitates the manufacturing and assembly of the outer cover and improves the efficiency of disassembly and assembly.

[0049] like Figure 1 As shown, the connector 1 includes a body 11, on which two beam mounting surfaces 12 and one column mounting surface 13 are provided. The two beam mounting surfaces 12 are located at both ends on the same side of the column mounting surface 13 and are perpendicular to the column mounting surface 13. There is an included angle A between the two beam mounting surfaces 12. The two beam mounting surfaces 12 are detachably connected to one end of the two beams 2 respectively. The column mounting surface 13 is detachably connected to one end of the column 3. The column 3 is perpendicular to the plane where the two beams 2 are located.

[0050] The connector 1 of this invention, applicable to the outer casing, taking a cuboid outer casing as an example, can protect desktop devices such as 3D laser printing equipment. Connector 1 has two beam mounting surfaces 12 and one column mounting surface 13, which can detachably connect two beams 2 and one column 3, facilitating the creation of corner components for the outer casing suitable for desktop devices. Furthermore, a frame structure outer casing can be obtained through multiple corner components. By adjusting the included angle A between the two beam mounting surfaces 12, a regular polygonal cross-section outer casing can be obtained, offering a wide range of applications and facilitating flexible assembly and disassembly to adjust volume and dimensions. Therefore, this invention achieves the assembly and manufacturing of an outer casing suitable for desktop devices through the connector 1, resulting in a short manufacturing cycle, easy assembly and disassembly, and improved efficiency in assembly and maintenance.

[0051] Optionally, the included angle A of the two beam mounting surfaces 12 is 90°, and the column 3 and the two beams 2 form mutually perpendicular corner components through the body 11.

[0052] like Figures 1-3 As shown, the two beam mounting surfaces 12 are at right angles to each other, and the two beams 2 on the two beam mounting surfaces 12 are connected perpendicularly to each other. After the column 3 is connected, it is perpendicular to the two beams 2, so a right-angle assembly can be obtained. The hexagonal frame outer cover can be formed by setting eight connectors 1 at the eight corners of the outer cover. Compared with the one-piece structure outer cover in the prior art, the outer cover of the present invention is assembled by connectors 1, which is convenient for disassembly and manufacturing and reduces costs.

[0053] Optionally, the body 11 has a cavity with a first opening on one side and beam mounting surfaces 12 at both ends. The beam mounting surfaces 12 have first connecting holes 121. The end face of the first opening is a column mounting surface 13, and the end face opposite to the first opening is provided with a second connecting hole 131. Multiple bolts 7 can pass through the first connecting hole 121 and the second connecting hole 131 to thread the beam 2 and the column 3 respectively.

[0054] It is understandable that, in order to address material costs and reduce weight, the body 11 of connector 1 is made of profile material. The body 11 is a profile with a groove structure having a first opening on one side, and sealing plates at both ends serving as beam mounting surfaces 12. The purpose of sealing is to allow for the machining of the first connection hole 121 on the sealing plate. Under this condition, the beam mounting surfaces 12 at both ends of the body 11 can adopt other structures with the first connection hole 121, such as a frame structure, with a solid structure in the center for machining the first connection hole 121, and the remaining part being a frame, further reducing weight and material usage. The end face of the first opening serves as the column mounting surface 13, which can directly contact and install with the column 3. It should be noted that the column 3 can also directly contact and install with the end face opposite the first opening, but this presents the problem of dust accumulation at the first opening, making it difficult to clean. It should also be noted that the cross-sectional dimensions of the beam mounting surface 12 are the same as the cross-sectional dimensions and shape of the beam 2, allowing for complete contact and connection. Similarly, the cross-sectional dimensions and shape of the column mounting surface 13 are the same as those of the column 3, enabling complete contact and connection. Beam 2 and column 3 are connected to connector 1 by bolt 7. Disassembly and installation can be achieved with conventional tools, making assembly more flexible and easier, and improving maintenance and disassembly efficiency.

[0055] Optionally, a groove 14 is provided on the end face opposite to the first opening, and a second connecting hole 131 is provided at the bottom of the groove 14. The groove depth of the groove 14 is not less than the head thickness of the bolt 7.

[0056] like Figure 2 As shown, by creating the groove 14, the head of the bolt 7 can be recessed into the groove 14, ensuring a smooth appearance without protrusions and good safety. The depth of the groove 14, while meeting the strength requirements of the body 11, is as close as possible to the first connecting hole 121 to reduce the connection length of the bolt 7. Simultaneously, since the bolt 7 penetrates the cavity of the body 11, the groove 14 and the bolt 7 together enhance the rigidity and connection strength of the connector 1. Preferably, the groove 14 penetrates the surface of the body 11 and conforms to the cross-sectional shape of the body 11, resulting in even better reinforcement.

[0057] Optionally, the outer sidewall 132 and inner sidewall 133 of the column mounting surface 13 are parallel to each other and respectively connect to the two beam mounting surfaces 12. The cross-sections of the outer sidewall 132 and the inner sidewall 133 are both isosceles trapezoids, and the two isosceles trapezoids are similar isosceles trapezoids.

[0058] like Figure 1 and Figure 2As shown, the outer wall 132 has a main plane portion and two secondary plane portions, which are connected to the two ends of the main plane portion, making the top view of the outer wall 132 an isosceles trapezoid. The angle between the two secondary plane portions and the main plane portion is an obtuse angle of 135°. Similarly, the connector 1 has an inner wall 133, which also has a main plane portion and two secondary plane portions, which are connected to the two ends of the main plane portion, making the top view of the outer wall 132 an isosceles trapezoid. The angle between the two secondary plane portions and the main plane portion is an obtuse angle of 135°. The main plane portion of the outer wall 132 is parallel to the main plane portion of the inner wall 133. The secondary plane portions of the outer wall 132 are parallel to the secondary plane portions of the inner wall 133 at the same end. Similarly, the centerline of the groove 14 is parallel to the outer wall 132 and the inner wall 133, and is located in the middle of the outer wall 132 and the inner wall 133. The body 11, with an isosceles trapezoidal cross-section, is easy to process and shape, and the resulting corner components have no sharp corners, making them safer.

[0059] Optionally, the outer wall 132 has an installation port 15 that communicates with the cavity, through which an installation tool can pass to tighten the bolt 7.

[0060] like Figure 2 The mounting port 15 is located on the main plane of the outer wall 132. Through the mounting port 15, installation tools such as screwdrivers can be inserted into the cavity of the body 11 to tighten the bolt 7. It should be noted that after the bolt 7 is installed, the mounting port 15 can be sealed with a rubber plug.

[0061] Optionally, both the beam mounting surface 12 and the column mounting surface 13 are provided with multiple positioning protrusions 16, which are spaced apart and can be inserted into the beam 2 and the column 3 for positioning.

[0062] like Figure 1As shown, four positioning protrusions 16 are provided on the beam mounting surface 12, respectively located on the four edges of the beam mounting surface 12. The positioning protrusions 16 are elongated. During installation, multiple positioning protrusions 16 are first inserted into the ends of the beam 2 to be connected. The four positioning protrusions 16 abut against the inner wall of the end face of the beam 2 (the inner wall of the first clamping groove 212) to achieve positioning. Then, the bolts 7 are connected. After connection, the rotation between the body 11 and the beam 2 is limited, making the structure more stable. In order to achieve a better positioning effect, the length of the positioning protrusions 16 is as close as possible to the maximum length of the corresponding positioning hole (first clamping groove 212) on the end face of the beam 2, resulting in a better positioning effect and simultaneous limitation of movement and rotation. The positioning protrusions 16 on the column mounting surface 13 are located on the inner wall of the outer side wall 132 of the body 11, protruding from the column mounting surface 13. The protruding end of the positioning protrusion 16 has a bevel, which is located on the side away from the cavity and serves as a guide when installing the column 3. Preferably, the column mounting surface 13 is provided with four positioning protrusions 16, which are located on the inner walls of the two sub-plane portions of the outer wall 132 and the inner walls of the two beam mounting surfaces 12, respectively.

[0063] The connector 1 provided by the present invention is suitable for the outer cover and can realize the outer cover that is easy to assemble and disassemble at the top corner of the outer cover. The following is an embodiment of the outer cover using a 3D printing equipment as an example.

[0064] like Figure 4 As shown, the outer cover provided by the present invention includes beams 2, columns 3, a top plate 4, and surrounding plates 5. Multiple surrounding plates 5 are arranged circumferentially around the top plate 4, forming a second opening opposite to the top plate 4 to cover the desktop device. Multiple beams 2 are located between the interconnected top plate 4 and surrounding plates 5, and multiple columns 3 are located between two interconnected surrounding plates 5. In the prior art, the above structure is fixed to a 3D printing device as a single unit, resulting in high manufacturing costs, long manufacturing cycles, and complex, time-consuming, and labor-intensive disassembly and assembly during maintenance. To improve the problems of long manufacturing cycles and low disassembly and assembly efficiency during maintenance, the outer cover provided by the present invention also includes connectors 1 suitable for the outer cover. Taking one side open and the other five sides sealed by the top plate 4 and surrounding plates 5 as an example, at the eight corners, two beams 2 and one column 3 are connected by connectors 1 suitable for the outer cover to form corner assemblies, which are located at the corners of the outer cover.

[0065] Through connector 1, beam 2 and column 3 are detachably connected to connector 1. During installation, beam 2 can be connected to the 3D printing equipment first, and then beam 2, column 3, top plate 4, and surrounding plate 5 can be assembled step by step through connector 1. When maintenance is required, the outer cover can be directly disassembled without having to remove it directly from the 3D printing equipment. It can be seen that by using connector 1, partial assembly and disassembly of the outer cover are facilitated, making it easier to disassemble and reassemble in stages during later maintenance or repair, thus improving the efficiency of disassembly and assembly during maintenance.

[0066] Optionally, the beam 2 includes a top beam 21 and a bottom beam 22. Both the top beam 21 and the bottom beam 22 include a central body 211. The side of the central body 211 is provided with a plurality of first clamping grooves 212 along the long axis of the central body 211 and with the groove direction perpendicular to the side of the central body 211. The edge of the top plate 4 and the top of the surrounding plate 5 can be inserted into the first clamping grooves 212 at the corresponding positions.

[0067] like Figure 5 As shown, the four beams 2 connected to the top plate 4 are the top beams 21, and the four beams 2 surrounding the second opening are the bottom beams 22. The top beams 21 and bottom beams 22 are in different positions, but can be beams 2 of the same structure. The lengths of the top beams 21 and bottom beams 22 at different positions are slightly different to facilitate the formation of a cube or cuboid outer casing. When the structures of the top beams 21 and bottom beams 22 are the same, such as... Figure 6 As shown, taking the top beam 21 as an example, the top beam 21 is a profile, and the central body 211 is a solid structure with a threaded hole 214 machined in the center for connection with the bolt 7. The bolt 7 passes through the first connecting hole 121 on the beam mounting surface 12 and can be threaded into the threaded hole 214 to fix the beam 2 to the beam mounting surface 12. The central body 211 has a square cross-section, and four right-angled arrow-shaped structural ribs are used at the four corners to form four first clamping grooves 212 on the side facing the central body 211. The first clamping grooves 212 extend along the long axis of the central body 211 and are parallel to each other. The opening direction of the first clamping grooves 212 is perpendicular to the side of the central body 211. The top plate 4 or the surrounding plate 5 can be inserted into the first clamping grooves 212 along the opening direction. Therefore, the thickness of the top plate 4 or the surrounding plate 5 is slightly less than the opening distance of the first clamping grooves 212. The central body 211 has a first clamping groove 212 around its perimeter, which facilitates redundant installation of other components and flexible adjustment of the position of the beam 2 during installation, making installation easier.

[0068] Optionally, at least one light bar groove 213 is provided on the circumferential edge of the central body 211 of the top beam 21. The groove direction of the light bar groove 213 is along the diagonal direction of the central body 211. The light bar can be inserted into the light bar groove 213 and the light-emitting surface of the light bar is set away from the central body 211.

[0069] like Figure 7As shown, when it is necessary to install light strips inside the outer casing, light strip grooves 213 can be opened on the top beam 21 or the bottom beam 22. Taking the opening of light strip grooves 213 on the top beam 21 as an example, the light strip grooves 213 are set along the long axis of the central body 211 and located on the edge of the central body 211. The groove direction of the light strip grooves 213 is directly opposite the edge of the central body 211, so that the light strip can have a 45° installation angle after installation to illuminate the inside of the outer casing. It is usually used in conjunction with a visible or transparent top plate 4 and / or a surrounding plate 5. The two side walls of the light strip grooves 213 are shared with the adjacent first clamping grooves 212. After the top plate 4 or the surrounding plate 5 is inserted, it can abut against the side walls of the light strip grooves 213 facing the first clamping grooves 212, and the positioning effect is good. When the top beam 21 or the bottom beam 22 is installed with the beam mounting surface 12, the positioning protrusions 16 can be inserted into the four first clamping grooves 212 and abut against the inner wall.

[0070] Optionally, the cross-sectional shape of the column 3 is the same as the shape of the column mounting surface 13 of the connector 1 suitable for the outer cover. The column 3 includes a hollow body 31 and two columns 32 symmetrically arranged at both ends of the hollow body 31. The two columns 32 are provided with two second clamping grooves 33 on the two sides away from the hollow body 31. The opening direction of the two second clamping grooves 33 is perpendicular to each other. The two sides of the enclosure 5 can be inserted into the second clamping grooves 33 of the two adjacent columns 3 respectively.

[0071] like Figure 8 As shown, the two columns 32 have the same structure as the central body 211. The ends of the columns 32 are provided with axial threaded holes 214 for mating with bolts 7. The two inner second clamping slots 33 are perpendicular to each other, and the two side panels 5 are respectively inserted into the two inner second clamping slots 33 to form mutually perpendicular side surfaces. The two outer second clamping slots 33 are used to install seals or accessories, such as sealing strips or emergency stop power supply components when installing door panels 51. Figure 8 The hollow body 31 is rectangular. The diagonals of the two columns 32 are collinear with one long side of the hollow body 31. A boss 34 along the long axis is provided on the inner side of this long side to facilitate the opening of holes at any position along the long axis of this long side to connect equipment accessories. The slotting direction of the two outer second clamping grooves 33 is perpendicular to the slotting direction of the corresponding inner two second clamping grooves 33. One sidewall of the two outer second clamping grooves 33 is the short side of the hollow body 31, and the groove opening is obtained by extending and bending the long side away from the column 32.

[0072] Optionally, at least one of the top plate 4 and the surrounding plate 5 is made of a transparent or translucent material.

[0073] Preferably, transparent or semi-transparent materials are selected from glass or acrylic sheets, which saves costs and meets the needs of visual observation. Combined with the light strip on the top beam 21, the operation of the desktop equipment inside can be easily observed from the outside of the outer casing.

[0074] Optionally, the enclosure 5 includes a door panel 51, one side of which is rotatably connected to a post 3, and the other side is rotatably openable or closed to an adjacent post 3.

[0075] like Figure 5 As shown, of the four enclosure panels 5, one is configured as a door panel 51. On the two uprights 3 on either side of the door panel 51, one is fitted with a hinge for rotating the door panel 51, and the other with a locking device to lock the door panel 51 when closed. The door panel 51 facilitates operation or maintenance of the 3D printing equipment and is generally positioned directly in front of the equipment. The door panel 51 also serves as an access port for maintenance work on the 3D printing equipment.

[0076] Optionally, the enclosure 5 also includes a back panel 52, the edges of which are detachably connected to the outer sides of the top beam 21, the bottom beam 22 and the two columns 3, respectively.

[0077] like Figure 5 As shown, one of the four enclosure panels 5 is configured as a back panel 52, positioned opposite the door panel 51. There is no insertion relationship between the back panel 52 and the top beam 21, bottom beam 22, or column 3. The back panel 52 rests against the outer surface of the plane containing the top beam 21, bottom beam 22, and column 3, and is secured with screws. The back panel 52 can serve as an access port for maintenance, repair, or operation of the internal 3D printing equipment. In this embodiment, the bottom end of the back panel 52 also has a through hole 53 through which data cables and power cables of the 3D printing equipment can be routed. When wiring is not required, the through hole 53 can serve as a ventilation hole. A fan can be installed at the through hole 53 to collect and treat polluting gases from the 3D printing equipment or to cool the equipment.
