Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 1 to 6:
the embodiment of the utility model provides a thermal printer with flip damping structure, including center 1 and flip 2, have two cylinders 11 on the inside lateral wall of center 1, flip 2 has two fixed legs 21, flip 2 can be turned up and match each other with center 1 and assemble together, two fixed legs 21 are rotatably assembled on two cylinders 11 respectively; the inner side wall of the middle frame 1 is provided with a convex part 12 at least above one cylinder 11 (optimally, the convex parts 12 are arranged above two cylinders 11 on the inner side wall of the middle frame 1), the convex part 12 can be a convex rib or a convex block and is in a linear shape, one side of the convex part 12 facing the flip cover 2 is provided with a contact surface 13, and the contact surface 13 is a plane; the convex part 12, the cylinder 11 and the middle frame 1 are of an integrated structure (for example, the convex part 12, the cylinder 11 and the middle frame 1 are integrally injection-molded).
When the thermal printer is turning up the flip 2, the friction contact (as shown in fig. 5) occurs between the flip 2 and the protrusion 12 (contact surface 13) to realize the interference, thereby playing a damping effect on the flip 2. Like this, can effectively slow down and alleviate flip 2 when the turn-up with the collision of center 1, the printer can not take place to shift because of the collision, bellying 12 can make flip 2 turn-up fix at the top simultaneously, be difficult for getting off from the high point upset, be favorable to the application of the structure that the spring was uncapped, guarantee that flip 2 hits the dynamics of the afterbody 14 of center 1 can the greatly reduced, and simple structure, the production and processing is easy, and is with low costs, including set up bellying 12 directly over cylinder 11, flip 2 speed of turning up backward has both been guaranteed, can guarantee again that flip 2 rubs with bellying 12 when turning up to the afterbody 14 that is close to center 1, do not collide with center 1.
In addition, one end (the end far away from the tail part 14) of the protruding part 12 is provided with a guiding inclined surface 15 towards one side of the flip cover 2, which is beneficial to guiding the flip cover 2 to the contact surface 13 of the protruding part 12, and ensures that the flip cover 2 is smoothly and continuously flipped backwards.
The height of the protrusion 12 on the inner side wall of the middle frame 1 gradually increases toward the tail 14 of the middle frame 1, which may be specifically: the contact surface 13 of the projection 12 is a slope that gradually slopes toward the flip 2 toward the tail 14. In this way, when the flip 2 is flipped up to be close to the tail 14 of the middle frame 1, the friction between the protruding portion 12 (the contact surface 13) and the flip 2 is gradually increased, and the flipping speed of the flip 2 is gradually reduced until being close to the tail 14, so that the flip 2 is more accurately controlled to be flipped up, and the collision with the tail 14 of the middle frame 1 is prevented.
Of course, the contact surface 13 of the protrusion 12 may be a plane, and the end near the tail 14 gradually inclines toward the flip 2, and the protrusion 12 is in a circular arc shape.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations are also considered as the protection scope of the present invention.
