Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, in particular to a CD player. Background Art

[0002] CD players were once very popular portable audio-visual devices. With the development of Bluetooth technology, traditional CD players have been given new technological impetus. CD players are all equipped with a CD door to cover the CD disc. The CD door is usually equipped with left and right shaft seats that match the left and right shaft parts on the main unit. The two shaft parts respectively extend outward with a door shaft and a limit shaft. The two shaft seats are respectively provided with a door shaft hole corresponding to the door shaft and a limit shaft hole corresponding to the limit shaft. The limit shaft holes are long arc-shaped holes. During installation, first align the shaft part on one side with the shaft seat, install the door shaft and limit shaft into the corresponding door shaft hole and limit shaft hole, and then install the shaft part and shaft seat on the other side. Because there are door shafts and limit shafts on both sides, it is very difficult to buckle the limit shaft into the limit shaft hole during assembly. This is time-consuming and labor-intensive, not only low assembly efficiency, but also high labor intensity for workers, cumbersome operation, and easy to scratch hands. Utility Model Content

[0003] The utility model aims to solve the defects of the prior art and provide a CD player with a simple structure, a more reasonable design, a more convenient and labor-saving assembly operation, a higher assembly efficiency and the ability to reduce the labor intensity of workers.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a CD player with easier assembly, comprising a main unit, which is equipped with a CD door; a first shaft seat and a second shaft seat are provided on the inner side of the CD door, the first shaft seat and the second shaft seat are both provided with door shaft holes, and a long arc-shaped limiting shaft hole is provided next to the door shaft hole of the first shaft seat; a first shaft portion and a second shaft portion are provided on the shell of the main unit, and a first mounting hole and a second mounting hole are respectively provided next to the first shaft portion and the second shaft portion, the first shaft portion and the second shaft portion are both provided with door shafts, and a limiting shaft is provided next to the door shaft of the first shaft portion, and the CD door is assembled and fixed to the main unit by inserting the first shaft seat into the first mounting hole and the second shaft seat into the second mounting hole so that the door shaft is installed in the corresponding door shaft hole and the limiting shaft is installed in the limiting shaft hole. The characteristic is that a limiting bone extends forward from the second shaft seat, and the limiting bone is recessed and contracted inwardly relative to the main body of the second shaft seat. After the second shaft seat and the second shaft portion are assembled and fixed, the limiting bone is inserted into the second mounting hole and movably clamps the inner surface of the shell of the main unit.

[0005] Furthermore, the position of the inner surface of the shell of the main body relative to the limiting bone is set as an inclined surface, and the surface of the limiting bone is stuck on the inclined surface.

[0006] Furthermore, an auxiliary limit rod is provided on the inner side of the CD door, which is located between the first axle seat and the second axle seat; a third mounting hole is provided on the shell of the main unit, which is located between the first mounting hole and the second mounting hole, and the auxiliary limit rod is inserted into the third mounting hole and stuck on the inner side of the shell of the main unit.

[0007] Furthermore, a torsion spring is sleeved on the door shaft of the first shaft portion, and two ends of the torsion spring respectively press against the host and the CD door, so that the CD door can remain open when it is opened.

[0008] Furthermore, a gear is provided below the first mounting hole, and an arc-shaped rack is provided at the bottom of the first shaft seat, and the rack is engaged with the gear to realize stepless damping opening and closing of the CD door.

[0009] Furthermore, the limiting bone and the second shaft seat are an integrated structure, the first shaft seat, the second shaft seat and the auxiliary limiting rod are all an integrated structure with the CD door, and the first shaft portion and the second shaft portion are an integrated structure with the housing of the host.

[0010] The utility model retains the door shaft and the limit shaft on one side, while retaining the door shaft on the other side and eliminating the limit shaft. Instead, the limit shaft is replaced by a straight rod-shaped limit bone. During assembly, only the door shaft and the limit shaft on one side need to be installed, and then the door shaft on the other side is installed. The limit bone will be inserted into the corresponding installation hole at the same time and contact with the housing of the main unit to play a limiting role. In this way, there is no need to install the limit shaft on the other side, making the assembly operation more convenient and labor-saving, improving assembly efficiency, and reducing the labor intensity of workers.
