[0027] The present application provides a printer frame with a stable structure, including a positioning assembly 10, the positioning assembly 10 including a first positioning disk 11 and a second positioning disk 12; an adjustment assembly, wherein a plurality of adjustment assemblies are circumferentially distributed and arranged on the positioning assembly 10, the adjustment assembly including adjustment units symmetrically arranged on the first positioning disk 11 and the second positioning disk 12; a connecting rod 30, wherein the two adjustment units are connected to each other through the connecting rod 30; wherein the adjustment unit includes a support plate 20, one end of the support plate 20 is hinged to the positioning disk, and the other end is a free end, and the support plate 20 is close to the connection rod. A guide groove 23 is provided on one side of the rod 30, and a bottom wall of the guide groove 23 is provided with a plurality of first through holes 21 penetrating the support plate 20, and a second through hole 22 is provided on a side wall of the guide groove 23 close to the positioning plate, and the other side of the guide groove 23 opposite to the second through hole 22 penetrates the support plate 20, and guide blocks 40 located in the guide groove 23 and movable along the same are provided at both ends of the connecting rod 30, and the guide block 40 is provided with a retractable and movable locking tongue 50, and the locking tongue 50 can selectively enter the first through hole 21 or the second through hole 22 to form a limiting structure with the support plate 20.

[0028] One end of the support plate 20 is hinged to the positioning plate, and the free end of the support plate 20 can be turned around the hinged end. The two adjustment units of the same adjustment assembly are symmetrically arranged, and the two support plates 20 can be turned toward each other. A guide groove 23 is provided on the support plate 20, and the two ends of the connecting rod 30 are respectively connected to the guide groove 23 through a guide block 40. When the printer frame needs to be in use, the support plate 20 is in a horizontal state, and the locking tongue 50 cooperates with the first through hole 21. When the printer frame does not need to be used, the support plate 20 is in a vertical state, and the locking tongue 50 cooperates with the second through hole 22. The locking tongue 50 can selectively cooperate with the first through hole 21 or the second through hole 22, which can improve the stability of the structure.

[0029] Specifically, the printer frame structure described in this embodiment does not include structures such as print heads. The connecting rod 30 is used to connect the first positioning disk 11 and the second positioning disk 12. A belt that is driven vertically can also be provided on the connecting rod 30. A connecting structure is provided on the belt. A plurality of connecting structures on the connecting rod 30 are circumferentially distributed and connected to the print head. The movement of the nozzle in space is controlled by controlling the belt transmission. The print head is connected to the consumables through a hose. The first positioning disk 11 and the second positioning disk 12 have the same structure. In this embodiment, they are distinguished only for the convenience of description. The second positioning disk 12 can be used to place items to be printed.

[0030] It should be further explained that when the printer frame is in the folded state, the support plate 20 is in a vertical state, the axis of the connecting rod 30 is in a vertical state, the upper and lower ends of the connecting rod 30 are located in the guide groove 23, and the lock tongue 50 is located in the second through hole 22, forming a limit structure, improving the structural stability, and ensuring that the support plate 20 will not be unfolded at will; when the printer frame is in the unfolded state, the support plate 20 is in a horizontal state, the guide blocks 40 at both ends of the connecting rod 30 are located in the guide groove 23, the axis of the connecting rod 30 is in a vertical state, and the axis of the connecting rod 30 is perpendicular to the extension direction of the guide groove 23. At this time, the lock tongue 50 is located in the first through hole 21, forming a limit structure, improving the structural stability, and preventing the support plate 20 from folding at will. When transitioning from the folded state to the unfolded state, the lock tongue 50 is first withdrawn from the second through hole 22, and then the support plate 20 is turned over to make the support plate 20 in a horizontal state, and then the connecting rod 30 is moved horizontally to make the lock tongue 50 enter the first through hole 21 to form a limit structure.

[0031] There are three adjustment components in this embodiment, and the three adjustment components are arranged in a ring shape on the periphery of the adjustment component, and the corresponding central angles between the three adjustment components are 60 degrees.

[0032] In some embodiments, the plurality of first through holes 21 are arranged and distributed along the extending direction of the guide groove 23 , and the extending direction of the guide groove 23 is the radial direction of the positioning plate.

[0033] Specifically, by providing a plurality of first through holes 21 , the relative position of the connecting rod 30 is adjustable, so that the distance between the connecting rod 30 and the positioning plate can be changed according to actual needs, so as to change the printing space size of the printer.

[0034] In some embodiments, the cross-sectional shape of the guide groove 23 is an arc shape, and the outer shape of the guide block 40 is a spherical shape that matches the guide groove 23 .

[0035] Specifically, the cross-sectional shape of the guide groove 23 is a major arc, the guide block 40 is spherical, the guide block 40 can move along the guide groove 23, and the relative integrity of the guide block 40 and the support plate 20 is ensured, and the guide block 40 will not be separated from the guide groove 23. In addition, through the spherical connection, when the support plate 20 is turned over 90 degrees, the guide block 40 and the guide groove 23 can also be relatively rotated 90 degrees, so that the guide block 40 can be relatively rotated in the guide groove 23. It should be noted that when the support plate 20 rotates 90 degrees, the main line of the connecting rod 30 is always in a vertical state, and part of the connecting rod 30 is stored in the guide groove 23.

[0036] In some embodiments, the guide block 40 has a through slot, the connecting rod 30 has a receiving slot 51 connected to the through slot, one end of the locking tongue 50 is located in the through slot and the other end is located in the receiving slot 51, and a compression spring 53 is arranged between the locking tongue 50 and the bottom wall of the receiving slot 51.

[0037] Specifically, by providing a compression spring 53, the lock tongue 50 always has a tendency to move outward. When the lock tongue 50 is aligned with the first through hole 21 or the second through hole 22, the lock tongue 50 can automatically enter the first through hole 21 and the second through hole 22 under the action of the compression spring 53.

[0038] In some embodiments, a handle 54 is disposed on the side wall of the locking tongue 50 . The handle 54 passes through the side wall of the through slot. The side wall of the through slot is disposed with a clearance slot 55 for the handle 54 to move.

[0039] Specifically, by providing the handle 54, it is convenient for the operator to control the movement of the lock tongue 50 through the handle 54, so that the lock tongue 50 withdraws from the first through hole 21 or the second through hole 22, releases the locked state, and enables the support plate 20 to change its state.

[0040] In some embodiments, the width of the accommodating groove 51 is greater than the width of the through groove, and a baffle 52 is further provided at one end of the locking tongue 50 located at the accommodating groove 51 .

[0041] Specifically, the baffle 52 is always located in the accommodating groove 51 to limit the extreme position of the outward movement of the locking tongue 50, thereby preventing the locking tongue 50 from popping out of the through groove and losing its function.

[0042] In some embodiments, the outer diameter of the connecting rod 30 is smaller than the slot width of the guide slot 23 .

[0043] Specifically, when the support plate 20 is turned over 90 degrees and is in a vertical state, a portion of the connecting rod 30 can be accommodated in the guide groove 23 without changing the axial direction of the connecting rod 30.

[0044] In some embodiments, the connecting rod 30 includes a first rod body 31 and a second rod body 32. The first rod body 31 has a storage groove, and the lower end of the second rod body 32 can be partially accommodated in the storage groove. The first rod body 31 is provided with a plurality of first limiting holes distributed in the vertical direction, and the second rod body 32 is provided with a second limiting hole that can be aligned with the first limiting hole. After the first limiting hole and the second limiting hole are aligned, they are connected by a locking pin.

[0045] Specifically, by configuring the connecting rod 30 to be a first rod body 31 and a second rod body 32, the overall length of the connecting rod 30 can be adjusted. When the support plates 20 are transformed from a horizontal state to a vertical state, the distance between the guide grooves 23 of the two support plates 20 may become smaller. At this time, by reducing the overall length of the connecting rod 30, the two ends of the connecting rod 30 can still connect the two support plates 20.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
