Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] It should be noted that all the expressions using "first" and "second" in the embodiments of the present utility model are used to distinguish two entities or parameters with the same name but different, so "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present utility model. This will not be elaborated one by one in the subsequent embodiments.

[0025] The direction and position terms mentioned in the present utility model, such as "up", "down", "front", "rear", "left", "right", "inside", "outside", "top", "bottom", "side", etc., are only with reference to the direction or position of the accompanying drawings. Therefore, the direction and position terms used are for explaining and understanding the present utility model, rather than a limitation on the protection scope of the present utility model.

[0026] As Figures 1 to 6 shown, in an embodiment of the present utility model, a bridge power supply with a ventilation quick interface includes a main body bracket 1 and a ventilation device 2 provided on the main body bracket 1, and further includes an air duct 3 and a quick-connect component. The quick-connect component includes a mating interface 4 at the bottom of the ventilation device 2 and a docking head 5 at the end of the air duct 3. Both the mating interface 4 and the docking head 5 are hollow annular structures. A ring groove 6 is provided on the outer wall of the docking head 5, and a buckle 7 adapted to the ring groove 6 is provided on the outer wall of the mating interface 4. The mating interface 4 and the docking head 5 are inserted and connected, and when the mating interface 4 and the docking head 5 are inserted, they are further fixedly connected by the buckle 7 and the ring groove 6. The ventilation device 2 and the air duct 3 are connected together through the cooperation of the mating interface 4 and the docking head 5.

[0027] The beneficial effects of such a setting are as follows. The ventilation device on the bridge power supply of the present utility model is detachably connected to the air duct through a quick-connect component. When exhaust is not required, the air duct can be removed to prevent the air duct from blocking the view. Moreover, the quick-connect component includes a mating interface and a docking head that are plugged and connected, which is convenient for connection. Then, a fixed connection is formed through the snap-fastener and the annular groove in a snap-fit manner, and the installation of the air duct is both convenient and firm.

[0028] Furthermore, a mounting portion 8 for installing the snap-fastener 7 protrudes from the outer wall of the mating interface 4. Both middle portions of the two sides of the snap-fastener 7 protrude with a rotating shaft 9. Through holes 10 adapted to the rotating shaft 9 are respectively formed on both sides of the mounting portion 8, and the snap-fastener 7 is rotatably connected to the mounting portion 8 through the rotating shaft 9.

[0029] The beneficial effects of such a setting are as follows. The snap-fastener can rotate, that is, a button structure is formed. Pressing the snap-fastener can separate it from the annular groove, which is convenient for disassembly.

[0030] Furthermore, a groove 11 for the snap-fastener 7 to extend into is provided in the middle of the mounting portion 8. A spring 12 is arranged in the groove 11. One end of the spring 12 abuts against the inner wall of the groove 11, and the other end abuts against the inner wall above the corresponding rotating shaft 9 of the snap-fastener 7. A convex ring 13 for the spring 12 to extend into protrudes from the inner wall of the groove 11. An anti-slip pattern layer 14 is provided on the outer wall of the snap-fastener 7 at the position corresponding to the abutting spring 12.

[0031] The beneficial effects of such a setting are as follows. The snap-fastener is reset by the elastic force of the spring, and keeps being snap-fitted with the annular groove when the snap-fastener is not pressed, ensuring stable snap connection. The convex ring prevents the spring from twisting. If the spring twists, it will cause the direction of the elastic force to change, further affecting the inability of the snap-fastener to reset, further improving the stability. The anti-slip pattern layer improves the friction force for pressing the snap-fastener and increases the pressing feel.

[0032] Furthermore, a hook 15 is provided at the other end of the snap-fastener 7 away from the anti-slip pattern layer 14, and an arc surface 16 adapted to the inner wall of the annular groove 6 is provided at the end of the hook 15.

[0033] The beneficial effects of such a setting are as follows. The contact area between the hook and the annular groove is increased through the arc surface, further improving the stability of the snap connection between the snap-fastener and the annular groove.

[0034] Furthermore, a conical boss 17 is provided on the outer wall of the docking head 5, and a conical angle 18 adapted to the conical boss 17 is provided on one side of the end of the hook 15 away from the anti-slip pattern layer 14.

[0035] The beneficial effects of such a setting are as follows. During the insertion process of the docking head and the mating interface, the hook slides into the annular groove along the conical boss through the conical angle, achieving the effect of quick snap connection.

[0036] Furthermore, a baffle 19 protrudes from the edge of the mounting portion 8 close to the hook 15.

[0037] The beneficial effects of such a setting are as follows. By the baffle abutting against the buckle, the buckle is kept in an initial position convenient for the connector to be clamped, preventing the buckle from rotating too large an angle and getting misaligned.

[0038] Furthermore, at least two buckles 7 are provided and symmetrically distributed on both sides of the docking port 4.

[0039] The beneficial effects of such a setting are as follows. A pair of buckles ensure uniform force application, greatly improving the clamping stability.

[0040] Furthermore, the connector 5 and the docking port 4 are in a transition fit.

[0041] The beneficial effects of such a setting are as follows. The transition fit enables a certain frictional force between the connector and the docking port. When the buckle disengages from the annular groove, the connector will not directly disengage from the docking port due to the frictional force, and the connector needs to be pulled again to be separated, preventing the connector from falling and being damaged, thus improving safety.

[0042] Furthermore, a power supply module 20 and a light strip 21 are further provided on the main body bracket 1.

[0043] The beneficial effects of such a setting are as follows. The power supply module provides a socket for devices to be connected, and the light strip provides illumination, enriching the usage functions of the bridge power supply.

[0044] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
