Technical Field

[0001] This utility model relates to the field of USB connection structure technology, specifically to a tool-free USB connection structure for disassembling a computer chassis. Background Technology

[0002] As a component of a computer, the computer case primarily serves to house and secure various computer parts, providing support and protection. However, existing computer cases typically have USB ports that are directly and modularly plugged into the motherboard inside the case. If there aren't enough USB ports on the case, screws are needed to secure the ports to pre-drilled holes, which is inconvenient for manual assembly and disassembly. Therefore, this paper proposes a tool-free, removable USB connection structure for computer cases to solve these problems. Utility Model Content

Detailed Implementation

[0016] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please refer to the following: Figures 1-5 This utility model discloses a tool-free detachable USB connection structure for a computer chassis, comprising: a chassis body 1, a chassis rear cover 2 at the rear of the chassis body 1, a placement slot 3 for adding USB on the inner side of the lower part of the chassis rear cover 2, a baffle 15 at one end of the placement slot 3 on the inner side of the chassis rear cover 2, a slot reserved between the baffle 15 and the placement slot 3, the placement slot 3 being inserted into one end of a USB fixing plate 11 through the slot, trapezoidal sliding seats 4 symmetrically arranged on the upper and lower sides of the placement slot 3 away from the baffle 15, a convex limiting block 5 horizontally slidably connected to the trapezoidal sliding seat 4, a positioning rack 6 fixedly arranged on the inner side of the chassis rear cover 2 above the convex limiting block 5, a longitudinally sliding abutment rod 7 through the convex limiting block 5, and a positioning block 10 at the top of the abutment rod 7.

[0020] Combination Figure 2 and Figure 4 As shown, the positioning block 10 has a triangular structure and engages with the bottom of the positioning rack 6. The convex limiting block 5 has a spring groove 8 longitudinally opened inside, and a spring body 9 is provided inside the spring groove 8. The upward elastic force of the spring body 9 can keep the upward push against the rod 7, thereby making the positioning block 10 on the rod 7 engage with the positioning rack 6, which can limit the convex limiting block 5. The USB fixing plate 11 is provided with a USB interface 12. The number of USB interfaces 12 is at least one. The USB interface 12 is connected to the circuit board 13. The circuit board 13 is fixedly connected to one side of the USB fixing plate 11. One end of the circuit board 13 is provided with a connector 14.

[0021] The placement slots 3 are provided in several ways. One end of the convex limiting block 5 extends into the placement slot 3 to abut against the USB fixing plate 11. The bottom end of the abutting rod 7 is connected to a handle. The placement slot 3 is located at the USB interface 12 and has a hollow structure, so that the USB interface 12 on the USB fixing plate 11 can be exposed. The length of the placement slot 3 is greater than the length of the USB fixing plate 11, so that the USB fixing plate 11 can be placed into the placement slot 3.

[0022] Specifically, when using this utility model, simply drag the abutment rod 7 downwards by the handle, which will cause the abutment rod 7 to press down on the spring body 9. At the same time, the abutment rod 7 and the positioning block 10 will descend, causing the positioning block 10 to move away from the positioning rack 6. Then, the convex limiting block 5 can be moved along the trapezoidal slide seat 4, thereby causing the convex limiting block 5 to detach from the USB fixing plate 11. Then, the USB fixing plate 11, along with the USB interface 12 and the circuit board 13, can be quickly disassembled. Similarly, the USB fixing plate 11 can be quickly installed in the placement slot 3 for limiting and fixing.

[0023] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0024] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
