Description

Technical Field

[0001] This utility model belongs to the field of printer technology, specifically relating to a printer base structure. Background Technology

[0002] The printer frame is the core support structure of the printer, equivalent to the "skeleton" of the entire device. It is mainly used to support key internal components of the printer, such as the print head, ink cartridge / toner drum, transmission mechanism, paper delivery system, etc., and to ensure the relative positional accuracy and stable operation of each component.

[0003] In the prior art, for example, a thermal printer frame structure disclosed in Chinese Utility Model Patent (Announcement No. CN209224730U) improves the strength of the buckle by embedding a reinforcing piece into the cut and integrating it with the buckle through a cut inside the buckle. This effectively eliminates the phenomenon of buckle breakage after repeated flipping of the cover, increases service life, and is simple in structure and easy to manufacture.

[0004] However, the aforementioned prior art printer frame latches are of a one-piece structure. Although reinforcing plates are incorporated inside the latches, the mating end with the printer cover is still made of plastic. Under prolonged, high-frequency use, continuous friction inevitably occurs between the latch and the printer cover, leading to gradual wear of the plastic mating end. As wear intensifies, the latch will eventually fail due to insufficient structural strength. Because the latch and side panel are integrally molded, latch failure often necessitates replacing the entire side panel or even the entire frame assembly, significantly increasing the equipment's maintenance costs. Utility Model Content

[0005] The purpose of this invention is to provide a printer frame structure that addresses the issue that although a reinforcing plate is incorporated inside the latch, the mating end with the printer cover is still made of plastic. Under prolonged, high-frequency use, continuous friction inevitably occurs between the latch and the printer cover, leading to gradual wear of the plastic mating end. As wear intensifies, the latch eventually fails due to insufficient structural strength. Because the latch and side plate are integrally molded, latch failure often necessitates replacing the entire side plate or even the entire frame assembly, significantly increasing the subsequent maintenance costs of the equipment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a printer base frame structure, including a base frame, with side plates integrally installed on both sides of the base frame, and a buckle that mates with the printer cover installed on one side of each side plate, and an inner cavity opened at the connection end between each side plate and the buckle;

[0007] A retaining strip is fixedly adhered to the inner wall of the inner cavity. A fixing plate is movably installed at the opening end on the lateral side of the inner cavity. Two bottom blocks are symmetrically adhered to the bottom of the fixing plate. Each bottom block is installed in a rectangular opening at the lower end of the opening on the lateral side of the inner cavity.

[0008] In order to enable the buckle to align with the clip after being installed inside the cavity, thereby aligning the buckle with the side plate, as a preferred printer frame structure of this utility model, two side strips are symmetrically installed on the side of the clip away from the inner wall of the cavity, and an adhesive strip is glued to the outer wall of one side of each side strip. A docking strip is fixedly installed on the outer wall of the side of the buckle facing the opening of the cavity. A T-shaped groove is transversely opened inside the docking strip, and two positioning grooves are symmetrically opened on the inner wall of the T-shaped groove.

[0009] The side strip and the card strip are slidably installed in the T-slot, and the rubber strip on one side of the side strip is squeezed and installed in the positioning slot.

[0010] In order to enable the actuating ridge strips to smoothly drive the rotating block to rotate, thereby controlling the opening and closing of the fixed plate, as a printer base frame structure of this utility model, preferably, the top of the fixed plate is fixedly installed with a rotating block, the rotating block is rotatably installed in the recess extending upward from the opening end of the inner cavity, and a set of ridge strips are installed at equal intervals on the arc-shaped outer wall of the rotating block.

[0011] In order to fix the bottom block into the rectangular opening at the lower end of the horizontal side opening of the inner cavity, the fixing plate can be fixed in the side opening of the inner cavity. As a printer base frame structure of this utility model, preferably, the bottom block has an inwardly inclined upward notch on the outer wall near the bottom, and an insert is embedded in the notch of the bottom block.

[0012] The outer wall of the end of the insert is arc-shaped. A semi-circular groove is provided on one side of the insert. A reinforcing strip is embedded inside the semi-circular groove. The other side of the reinforcing strip is bonded to the inner wall of the rectangular opening at the lower end of the horizontal side opening of the inner cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When a new clip needs to be installed on the side panel, the fixing plate is flipped upwards using the rotating block, which opens one side of the inner cavity. The mating strip on one side of the clip is then installed into the inner cavity from the transverse opening end. As the mating strip enters the inner cavity, its T-slot will align with the clip and side strip. Once aligned, the clip can be initially installed on one side of the side panel.

[0015] Next, flip the fixing plate downwards so that the two bottom blocks of the fixing plate fit into the corresponding rectangular grooves below the opening end of the inner cavity. During this process, the bottom blocks will align with the insert strip, thus fixing the bottom blocks in the corresponding rectangular grooves below the opening end of the inner cavity. At this point, the fixing plate will be fixed in the transverse opening of the inner cavity, and one side of the fixed plate will press and fix the insert strip.

[0016] In summary, the mating strip can be fixed in the inner cavity by the cooperation of the above structures. This allows for the replacement of damaged clips, thereby extending the service life of the base frame and reducing the replacement cost under the integrated structure. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 7 The present invention provides the following technical solution: a printer base frame structure, including a base frame 1, with side plates 2 integrally installed on both sides of the base frame 1, and a buckle 3 that mates with the printer cover installed on one side of each side plate 2, and an inner cavity 4 opened at the connection end between each side plate 2 and the buckle 3.

[0028] A retaining strip 5 is fixedly bonded to the inner wall of the inner cavity 4. A fixing plate 6 is movably installed at the opening end of the inner cavity 4 on one side. Two bottom blocks 7 are symmetrically bonded to the bottom of the fixing plate 6. Each bottom block 7 is installed in a rectangular opening at the lower end of the opening on one side of the inner cavity 4.

[0029] Preferably, two side strips 51 are symmetrically installed on the side of the clip 5 away from the inner wall of the inner cavity 4, and an adhesive strip 52 is glued to the outer wall of one side of each side strip 51. A connecting strip 31 is fixedly installed on the outer wall of the side of the clip 3 facing the opening of the inner cavity 4. A T-shaped groove 32 is opened horizontally inside the connecting strip 31, and two positioning grooves 33 are symmetrically opened on the inner wall of the T-shaped groove 32.

[0030] The side strip 51 and the connecting end of the card strip 5 are slidably installed in the T-slot 32, and the rubber strip 52 on one side of the side strip 51 is squeezed and installed in the positioning slot 33.

[0031] In actual use, after the clip 5 and side strip 51 are connected to the T-slot 32, the adhesive strip 52 on the side strip 51 will be squeezed between the side strip 51 and the positioning groove 33, thereby improving the firmness of the clip 5 and side strip 51 after being connected to the T-slot 32.

[0032] Preferably, a rotating block 61 is fixedly installed on the top of the fixed plate 6. The rotating block 61 is rotatably installed in the recess extending upward from the opening end of the inner cavity 4. A set of protruding strips 62 are installed at equal intervals on the arc-shaped outer wall of the rotating block 61.

[0033] When the fixing plate 6 is closed in the opening on the lateral side of the inner cavity 4, the outer wall on one side of the fixing plate 6 will press one end of the mating strip 31, which can effectively fix the mating strip 31 in the inner cavity 4.

[0034] When operating the fixed plate 6 to open or close, the protrusion 62 can be flicked with the finger, which will increase the friction between it and the rotating block 61, thereby effectively turning the rotating block 61. The rotating block 61 will drive the fixed plate 6 to rotate through the rotating shafts on both sides, thus enabling the opening and closing operation of the fixed plate 6.

[0035] Preferably, a notch is provided on the outer wall of the bottom block 7 near the bottom, and an insert 71 is fitted into the notch of the bottom block 7.

[0036] The outer wall of the end of the insert 71 is arc-shaped. A semi-circular groove is provided on one side of the insert 71. A reinforcing strip 72 is embedded inside the semi-circular groove. The other side of the reinforcing strip 72 is bonded to the inner wall of the rectangular opening at the lower end of the transverse side opening of the inner cavity 4.

[0037] The insert 71 is fixedly installed on the inner wall of the rectangular opening at the lower end of the horizontal side opening of the inner cavity 4 by the reinforcing strip 72. When in use, the hard rubber insert 71 will be inserted into the bottom block 7 along the trajectory of the notch. Once fully inserted, the bottom block 7 can be fixed in the rectangular opening at the lower end of the horizontal side opening of the inner cavity 4.

[0038] In practical use, when a new clip 3 needs to be installed on the side plate 2, the restriction of the fixing plate 6 on the lateral opening of the inner cavity 4 must first be lifted. The user uses their thumb to turn the rotating block 61 on the top of the fixing plate 6, flipping it upwards along its rotation axis. As the fixing plate 6 flips, the originally closed opening on one side of the inner cavity 4 is opened, exposing the internal opening for installing the clip 3.

[0039] Align the end of the buckle 3 with the connecting strip 31, align it with the transverse opening of the inner cavity 4, and push it in smoothly. During the pushing process, the T-slot 32 on one side of the connecting strip 31 forms a mortise and tenon joint with the buckle strip 5 and the side strip 51. After the buckle strip 5 and the side strip 51 are connected with the T-slot 32, the buckle 3 can be initially positioned, so that it is firmly attached to one side of the side plate 2.

[0040] After initial installation, the clips 3 need to be reinforced a second time using the fixing plate 6. Flip the fixing plate 6 back down, ensuring that the two bottom blocks 7 of the fixing plate 6 are precisely engaged in the corresponding rectangular grooves below the opening of the inner cavity 4. When the bottom blocks 7 align with the insert 71, the curved end of the insert 71 will insert into the inclined notch on one side of the bottom block 7, thus fixing the bottom block 7 in the corresponding rectangular groove below the opening of the inner cavity 4.

[0041] After the fixing plate 6 is fixed, it will generate a uniform compressive force on one side of the mating strip 31 on the side plate 2. In summary, the structure provided by this technical solution facilitates the quick replacement of the damaged buckle 3, thereby significantly improving the overall service life and structural stability of the base frame 1 without affecting other structures of the base frame 1.

[0042] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
