Technical Field
[0001] The utility model relates to the technical field of printers, in particular to a door cover elastic support component and a printer. Background Art
[0002] Frequent opening and closing of printer doors is a common occurrence during printer operation. Traditional fixed-length support rods often fail to adapt well to the size and weight differences of printer door covers of different models. This can lead to unstable support, failure to maintain the ideal opening angle, and inconvenience during opening and closing.
[0003] As printer technology continues to advance, their structures become increasingly complex, requiring greater clearance and stability when the door is open. For example, when replacing ink cartridges, clearing paper jams, or performing internal maintenance, the door needs to remain securely open to allow operators to operate conveniently and safely. To address this, some manufacturers have designed support rods to support the door, but these rods lack the ability to retract or retract, or the support rods themselves lack sufficient retraction capabilities. These rods can extend and retract smoothly, lock loosely, or become prone to wear and deformation after long-term use, impacting their lifespan and support effectiveness. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, unless otherwise specified, "multiple" means two or more.
[0029] Reference Figures 1 to 5 As shown, the utility model provides a door cover elastic support assembly, comprising:
[0030] A first rod 10 having a sliding structure 11 disposed thereon;
[0031] A second rod 20, one end of which is movably sleeved on one end of the first rod 10, and the first rod 10 can slide axially relative to the second rod 20. The second rod 20 is provided with a locking member 21 that cooperates with the sliding structure 11;
[0032] The elastic member 30 is disposed in the first rod 10 and / or the second rod 20 . One end of the elastic member 30 abuts against the first rod 10 , and the other end abuts against the second rod 20 .
[0033] In the present application, the interiors of the first rod 10 and the second rod 20 are both hollow. To enhance strength, only the connected ends are hollow, which also provides space for the installation of the elastic member 30. It should be noted that in the present application, the ends of the elastic member 30 are always pressed against the first rod 10 and the second rod 20, respectively, so that the first rod 10 and the second rod 20 can maintain a supporting force even in the deployed state. Furthermore, in the above-described embodiment, the elastic member 30 is a spring, and the sliding structure 11 can be a sliding sleeve structure. Of course, in some embodiments, the sliding structure 11 can be a direct extension of a portion of the first rod 10, which facilitates processing.
[0034] The door cover elastic support assembly of the present invention adopts a double-rod design, in which the first rod 10 is movably inserted into the second rod 20, and the two are supported and connected by an elastic member 30. The first rod is slidably installed in the second rod 20 through a sliding structure 11. This can reduce the contact area between the first rod 10 and the second rod 20, thereby avoiding movement jamming when the first rod 10 and the second rod 20 slide relative to each other; at the same time, a locking member 21 that cooperates with the sliding structure 11 is provided on the second rod 20. This design can relatively lock the first rod 10 and the second rod 20, thereby improving the locking ability.
[0035] In some possible implementations, in order to prevent the first rod 10 and the second rod 20 from rotating relative to each other during the sliding process, and also to limit the relative sliding direction of the first rod 10 and the second rod 20, in one embodiment of the present application, at least one protrusion 12 is provided on the sliding structure 11, and a sliding groove for cooperating with the protrusion 12 is provided on the inner wall of the second rod 20.
[0036] In the technical solution of the above-mentioned improved embodiment, to prevent the first rod 10 from directly sliding out of the second rod 20, the slide groove includes a main portion 22 and a slide-out portion 23. The main portion 22 and the slide-out portion 23 are arranged in parallel and connected by a connecting portion 24. During normal use, the protrusion 12 is first aligned with the slide-out portion 23, and then the two slide relative to each other to the bottom of the slide-out portion 23. Then, by rotating the first rod 10 and the second rod 20 relative to each other, the protrusion 12 can be rotated from the slide-out portion 23 into the main portion 22. At this time, the first rod 10 cannot be directly pulled out of the second rod 20. This can also, to a certain extent, prevent the first rod 10 from separating from the second rod 20 due to the elastic force of the elastic member 30 when in the deployed state.
[0037] See also Figures 3 and 4 In one embodiment of the present application, in order to improve the sliding smoothness between the sliding structure 11 and the second rod 20, the sliding structure 11 is an annular boss, and the outer diameter of the annular boss abuts against the inner wall of the second rod 20. Such a design is conducive to direct processing.
[0038] See also Figure 3 and Figure 4 In one embodiment of the present application, in order to accommodate the locking member 21 , a mounting groove 25 is provided on the end of the second rod 20 , and the locking member 21 is disposed in the mounting groove 25 .
[0039] In the above embodiment, the locking member 21 is a buckle that can be buckled onto the end surface of the sliding structure 11. A limiting block 13 is provided on the outer wall of the first rod 10. A receiving position for the buckle is formed between the limiting block 13 and the end surface of the sliding structure 11. A slope 14 is provided on the end of the limiting block 13 adjacent to the receiving position. The slope 14 is designed to facilitate the sliding of the limiting block 13 relative to the buckle, causing the buckle to deform and slide out of the receiving position, thereby allowing the first rod 10 to retract relative to the second rod 20.
[0040] In the above-mentioned improved solution, a slope 26 is provided on the radial end of the buckle facing the first rod 10, and a tongue is provided on the bottom of the slope 26, wherein the tongue is locked in the accommodating position when the first rod 10 is in the unfolded state. The main function of the slope 26 is to facilitate the first rod 10 to slide relative to the second rod 20, at which time the outer wall of the first rod 10 can better force the buckle to deform.
[0041] In some possible implementations, since the sliding structure 11 is only provided at one end of the first rod 10, the other end of the first rod 10 is likely to have no contact with the inner wall of the second rod 20 after being stored, which may easily cause the first rod 10 to tilt relative to the second rod 20. In order to avoid such a situation, in one embodiment of the present application, at least one ridge 15 is provided on the outer wall of the first rod 10, and the diameter of the virtual circle on which the outer side surface of the ridge 15 is located is equal to the diameter of the outer wall of the sliding structure 11. Through such a configuration, the ridge 15 can abut against the inner wall of the second rod 20, thereby preventing the first rod 10 from maintaining close contact as a whole when relative sliding occurs to the second rod 20, thereby avoiding lateral deviation.
[0042] See also Figures 1 to 2 In one embodiment of the present application, to facilitate installation, a mounting seat 27 is provided on the non-open end of the second rod 20. A mounting plate 28 is provided on the mounting seat 27, and the mounting plate 28 has mounting holes. Furthermore, a mounting ear 16 is provided on the end of the first rod 10 that does not mate with the second rod 20. In the above embodiment, the mounting plate 28 and the mounting ear 16 are located on different structures. In this application, the mounting ear 16 is located on the printer door, while the mounting plate 28 is mounted on the printer.
[0043] See also Figure 6 The present invention also provides a printer, which includes a main body 40 and a door cover 50 hinged to the main body, and a door cover elastic support component is arranged between the main body 40 and the door cover 50, wherein the end of the first rod 10 away from the second rod 20 is hinged to the door cover 50, and the end of the second rod 20 away from the first rod 10 is hinged to the main body 40.
[0044] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention shall be covered by the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
