The cover body and the main body are hinged through a housing structure, so that the cover body and the main body rotate relative to each other around a fixed pivot axis. Since the pivot axis is fixed, if the cover body is designed to sink into the main body, the single-degree-of-freedom rotation structure cannot open the cover at this time. Furthermore, it is not conducive to the miniaturization design of electrical equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a housing structure and a printer to solve the problem that in the related technology, since the pivot axis is fixed, if the cover body is designed to sink into the main body, the single-degree-of-freedom rotation structure cannot open the cover at this time. Furthermore, it is not conducive to the miniaturization design of electrical equipment.

The second pivot member is located in the receiving cavity and is fixedly connected to the main body. The first pivot member is provided with a pivot axis. The second pivot member is provided with a long hole extending along the first direction. The pivot axis is inserted into the long hole, so that the cover body has a first position located in the receiving cavity and a second position opening the receiving cavity relative to the main body.

[0009] As a preferred technical solution of the housing structure, when the cover body is in the first position, the side wall of the end of the long hole away from the cover body abuts against the pivot axis.

[0010] As a preferred technical solution of the housing structure, the hinge further includes a gear and a rack. The gear is fixedly arranged on the first pivot member. The gear is coaxially arranged with the pivot axis. The rack is arranged on the inner wall of the receiving cavity. The rack extends along the first direction. The gear meshes with the rack.

[0012] As a preferred technical solution of the housing structure, the second pivot member includes a support plate and a reinforcing rib plate. The support plate is fixedly arranged on the main body and the long hole is located on the support plate. The reinforcing rib plate is fixedly arranged on the main body, and the reinforcing rib plate is fixedly connected to a side wall of the support plate along the axial direction of the pivot shaft.

[0013] As a preferred technical solution of the housing structure, the distance between the pivot shaft and the cover body is a, and the distance between the long hole and the outer surface of the rear side wall of the main body is b, and a > b.

[0014] As a preferred technical solution of the housing structure, the first pivot member is provided with an avoidance groove, and the avoidance groove faces the rear side wall.

[0015] As a preferred technical solution of the housing structure, at least two hinges are provided, and the at least two hinges are arranged at intervals along the axial direction of the pivot shaft.

[0016] As a preferred technical solution of the housing structure, two hinges are provided. The two second pivot members are located between the two first pivot members.

The pivot shaft sequentially penetrates through the gear and the long hole. The gear is fixedly connected to the pivot shaft. The gear abuts against the second pivot member. A rack is arranged on the inner wall of the accommodating cavity. The rack extends along the first direction. The gear meshes with the rack.

[0017] On the other hand, the present utility model provides a printer, including the housing structure in any of the above solutions, wherein the main body is the printer body, and the cover body is the printer upper cover.

[0018] The beneficial effects of the present utility model are as follows:

[0019] The present utility model provides a housing structure and a printer. The housing structure includes a cover body, a main body, and a hinge. The main body is recessed with a receiving cavity along a first direction; the hinge includes a first pivoting member and a second pivoting member. The first pivoting member is fixedly connected to the cover body, and the second pivoting member is located in the receiving cavity and fixedly connected to the main body. The first pivoting member is provided with a pivoting shaft, and the second pivoting member is provided with a long slot extending along the first direction. The pivoting shaft is inserted into the long slot so that the cover body has a first position located in the receiving cavity and a second position opening the receiving cavity relative to the main body. Since the length direction of the long slot is consistent with the first direction, after the pivoting shaft is inserted into the long slot, the pivoting shaft can slide along the first direction and can also rotate around the axis of the pivoting shaft in the long slot. Therefore, the cover body can slide relative to the main body along the first direction and can also rotate relative to the main body around the axis of the pivoting shaft. Therefore, the cover body has a first position located in the receiving cavity and a second position extending out of the receiving cavity and opening the receiving cavity. Therefore, the above housing structure enables the cover body to be designed as a structure that sinks into the main body and does not prevent the cover body from rotating relative to the main body around the pivoting shaft, which is beneficial to the miniaturization of electrical equipment. When this housing is applied to a printer, the overall volume of the printer can be made smaller. Description of the Drawings

[0032] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0033] As Figures 1 to 6As shown, this embodiment provides a housing structure, which includes a cover 1, a main body 2, and a hinge 3. The main body 2 is recessed with a receiving cavity 21 along a first direction. The hinge 3 includes a first pivot member 31 and a second pivot member 32. The first pivot member 31 is fixedly connected to the cover 1, and the second pivot member 32 is located in the receiving cavity 21 and fixedly connected to the main body 2. The first pivot member 31 is provided with a pivot shaft 311, and the second pivot member 32 is provided with a long hole 3211 extending along the first direction. The pivot shaft 311 is inserted into the long hole 3211, so that the cover 1 has a first position located in the receiving cavity 21 relative to the main body 2 and a second position that opens the receiving cavity 21. Since the length direction of the long hole 3211 is consistent with the first direction, after the pivot shaft 311 is inserted into the long hole 3211, the pivot shaft 311 can slide along the first direction and can also rotate around the axis of the pivot shaft 311 in the long hole 3211. Therefore, the cover 1 can slide relative to the main body 2 along the first direction and can also rotate relative to the main body 2 around the axis of the pivot shaft 311. Therefore, the cover 1 has a first position located in the receiving cavity 21 and a second position that extends out of the receiving cavity 21 and opens the receiving cavity 21. It should be noted that in this embodiment, the cover 1 being located in the receiving cavity 21 means that the cover 1 is partially or entirely located in the receiving cavity, that is, when observed perpendicular to the first direction, at least part of the cover 1 overlaps with the main body 2. Therefore, the above housing structure enables the cover 1 to be designed as a structure that sinks into the main body 2 without hindering the rotation of the cover 1 relative to the main body 2 around the pivot shaft 311, which is beneficial to the miniaturization of electrical equipment.

[0034] Optionally, when the cover 1 is in the first position, the side wall of the end of the long hole 3211 away from the cover 1 abuts against the pivot shaft 311. In this embodiment, when the cover 1 is in the first position, the cover 1 is inserted into the receiving cavity 21. At this time, the side wall of the end of the long hole 3211 away from the cover 1 abuts against the pivot shaft 311 to limit the cover 1 and prevent the cover 1 from moving relative to the main body 2 in the direction of extending into the receiving cavity 21 along the first direction, achieving the positioning effect of the cover 1 and the main body 2.

[0035] Preferably, when the side wall of the end of the long hole 3211 away from the cover 1 abuts against the pivot shaft 311, the cover 1 is flush with the wall surface of the main body 2 where the receiving cavity 21 is provided.

[0036] Optionally, the hinge 3 further includes a gear 33 and a rack 34. The gear 33 is fixedly provided on the first pivot member 31. The gear 33 is coaxially arranged with the pivot shaft 311. The rack 34 is arranged on the inner wall of the accommodation cavity 21 and extends along a first direction. The gear 33 meshes with the rack 34. In this embodiment, since the gear 33 is coaxially arranged with the pivot shaft 311, when the cover body 1 rotates around the pivot shaft 311, the gear 33 rotates synchronously around the axis of the pivot shaft 311. Since the gear 33 meshes with the rack 34 and the rack 34 extends along the first direction, the pivot shaft 311 moves synchronously along the first direction. Therefore, when the cover body 1 switches from the first position to the second position, while the pivot shaft 311 rotates forward, the pivot shaft 311 moves in the direction of protruding from the accommodation cavity 21, so that the cover body 1 protrudes from the accommodation cavity 21, and thus there will be no rotational interference with the main body 2. When the cover body 1 switches from the second position to the first position, while the pivot shaft 311 rotates reversely, the pivot shaft 311 moves in the direction of extending into the accommodation cavity 21, so that the cover body 1 extends into the accommodation cavity 21.

[0037] Optionally, the gear 33 is sleeved on the pivot shaft 311 and fixedly connected to the pivot shaft 311. In this embodiment, the gear 33 is sleeved on the pivot shaft 311, thus ensuring the coaxial arrangement of the gear 33 and the pivot shaft 311. In other embodiments, the gear 33 and the pivot shaft 311 may also be integrally formed.

[0038] Optionally, the second pivot member 32 includes a support plate 321 and a reinforcing rib plate 322. The support plate 321 is fixedly provided on the main body 2 and the long hole 3211 is located on the support plate 321. The reinforcing rib plate 322 is fixedly provided on the main body 2, and the reinforcing rib plate 322 is fixedly connected to a side wall of the support plate 321 along the axial direction of the pivot shaft 311. In this embodiment, the support plate 321 is located in the accommodation cavity 21 and is fixedly connected to the bottom wall and / or side wall of the accommodation cavity 21 corresponding to the support plate 321. The reinforcing rib plate 322 is fixedly connected to a side wall of the support plate 321 along the axial direction of the pivot shaft 311, which can strengthen the support plate 321 along the axial direction of the pivot shaft 311. Specifically, the support plate 321 and the reinforcing rib plate 322 form an L-shaped plate.

[0039] Optionally, the distance between the pivot shaft 311 and the cover body 1 is a, and the distance between the long hole 3211 and the outer side surface of the rear side wall of the main body 2 is b, and a > b. In this embodiment, the purpose of the above setting is that when the cover body 1 is in the second position, the cover body 1 and the pivot shaft 311 can be respectively located on both sides of the rear side wall, and at this time, the cover body 1 abuts against the rear side wall to limit the relative positions of the cover body 1 and the main body 2.

[0040] Optionally, the first pivot member 31 is provided with an avoidance groove 312 opposite to the rear side wall. In this embodiment, during the process of the cover 1 switching from the first position to the second position, the function of the avoidance groove 312 is to prevent movement interference between the first pivot member 31 and the rear side wall before the cover 1 abuts against the rear side wall.

[0041] Optionally, at least two hinges 3 are provided, and the at least two hinges 3 are arranged at intervals along the axial direction of the pivot shaft 311. In this embodiment, the above arrangement can improve the stability of the cover 1 relative to the main body 2 when switching between the first position and the second position, and prevent the jamming problem caused by uneven force. Specifically, the number of the hinges 3 can be two, three, four, etc.

[0042] Optionally, two hinges 3 are provided. The two second pivot members 32 are located between the two first pivot members 31. The hinge 3 further includes a gear 33 and a rack 34. A pivot shaft 311 is fixedly provided on a side surface of the first pivot member 31 close to the second pivot member 32. The pivot shaft 311 sequentially passes through the gear 33 and the long hole 3211. The gear 33 is fixedly connected to the pivot shaft 311. The gear 33 abuts against the second pivot member 32. A rack 34 is provided on the inner wall of the accommodation cavity 21. The rack 34 extends along the first direction. The gear 33 and the rack 34 are meshed. In this embodiment, the two second pivot members 32 are located between the two first pivot members 31, and the gear 33 abuts against the corresponding second pivot member 32, so that the two pivot shafts 311 cannot be disengaged from the corresponding long holes 3211 without external force. At the same time, the movement of the cover 1 relative to the main body 2 along the axial direction of the pivot shaft 311 is also restricted.

[0043] On the other hand, the present invention provides a printer, including the housing structure in the above solution, where the main body 2 is the printer body and the cover 1 is the printer upper cover.

[0044] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
