[0046] The following is combined with Figures 1 to 8 This application is described in further detail.
[0047] The present application provides a protective cover, such as Figure 1 As shown, the protective cover 1 can be installed on the common connector 2 of the oxygen supply pipes to protect the common connector 2 of the oxygen supply pipes.
[0048] like Figure 2 As shown, the oxygen delivery tube common joint 2 has a joint portion 21, and a first connecting ear piece 22 is arranged on the joint portion 21. The protective cover 1 comprises: a sleeve 12, a top cover 11 and a locking hook 13, a second connecting ear piece 14 is arranged on the sleeve 12, the sleeve 12 is sleeved on the joint portion 21 of the oxygen delivery tube common joint 2, and is fixedly connected to the first connecting ear piece 22 through the second connecting ear piece 14; the top cover 11 is hinged to the sleeve 12, the top cover 11 is covered on the joint portion 21 and the sleeve 12, and a hanging portion is arranged on the top cover 11; one end of the locking hook 13 is hinged to the sleeve 12, and the other end is matched and connected with the hanging portion of the top cover 11.
[0049] In a preferred embodiment of the present application, three first connecting lugs 22 on the oxygen delivery tube common joint 2 are evenly arranged along the circumference of the joint portion 21. Similarly, three second connecting lugs 14 are evenly arranged along the circumference of the sleeve 12. The second connecting lugs 14 are fixedly connected to the first connecting lugs 22 by bolts.
[0050] In a preferred embodiment of the present application, Figure 3 As shown, a plane mounting portion 15 is provided on the side wall of the sleeve 12, and the plane mounting portion 15 is a plane structure. A first single-ear joint is provided on the plane mounting portion 15, and a second single-ear joint is provided on the top cover 11, and the second single-ear joint is hinged to the first single-ear joint through a pin. In this embodiment, three first single-ear joints are provided, and two second single-ear joints are provided. The first single-ear joint and the second single-ear joint are arranged at intervals and hinged through a pin. Advantageously, a first torsion spring is provided at the hinge between the second single-ear joint and the first single-ear joint, and the top cover 11 is kept in a normally open position through the first torsion spring.
[0051] In this embodiment, a notch is provided on the sleeve 12. When the top cover 11 is placed on the sleeve 12, the hooking portion of the top cover 11 is located at the notch. The upper surface of the hooking portion of the top cover 11 is a plane, which is convenient for matching with the lock hook 13. Figure 4 As shown, the top cover 11 can be covered on the joint part 21 and the sleeve 12, wherein a first rubber ring is provided at the matching connection between the top cover 11 and the joint part 21. A second rubber ring is provided at the matching connection between the top cover 11 and the sleeve 12.
[0052] In a preferred embodiment of the present application, the locking hook 13 is used to ensure that the top cover 11 is restrained when the protective cover is not in use, thereby ensuring that the top cover 11 is not opened. Figure 5 As shown, a double-ear joint is provided on the sleeve 12, a mounting hole is provided on the lock hook 13, and the lock hook 13 is hinged to the double-ear joint through a pin. Advantageously, a second torsion spring is provided at the hinge between the lock hook 13 and the double-ear joint, and the lock hook 13 is in a normally closed position through the second torsion spring. In this embodiment, a pressure application surface is provided on the side of the lower end of the lock hook 13 away from the sleeve 12.
[0053] The protective cover of the present application also includes a C-shaped safety piece 16, a safety hole is provided on the double-ear joint, and a safety slot is provided on the double-ear joint and the lock hook 13; the safety piece 16 is nested in the safety slot, and its two ends are plugged into the safety hole. The safety piece 16 can ensure that the lock hook 13 will not automatically pop open when the protective cover is not working. In the preferred embodiment of the present application, the end axes of the two ends of the safety piece 16 are not coaxial to prevent self-rotation.
[0054] In a preferred embodiment of the present application, the upper surface of the lock hook 13 is a curved surface, and when the safety member 16 is opened, the top cover 11 is pressed downward so that the top cover 11 directly enters a locked state.
[0055] The steps for changing the protective cover of this application from the closed state to the open state are as follows:
[0056] ② Turn the safety piece 16 upward;
[0057] ③ Press the pressure application surface from the root of the lock hook 13 to rotate the lock hook 13 outward;
[0058] ④ Due to the action of the torsion spring at the root of the top cover 11, the top cover 11 automatically opens upwards;
[0059] ⑤ After the top cover 11 is opened upward, the pressure applied to the root of the lock hook 13 is cancelled, and the lock hook 13 rotates inwardly due to the torsion spring, and the inner side of the lock hook 13 rests on the notch of the sleeve 12.
[0060] The steps for changing the protective cover of this application from the open state to the closed state are as follows:
[0061] ① Keep the safety piece 16 open, press the top cover 11, and press the end of the top cover 11 on the upper surface of the lock hook 13 to rotate the lock hook 13 outward until the top cover 11 is closed;
[0062] ② After the top cover 11 is closed, due to the action of the torsion spring at the root of the lock hook 13, the lock hook 13 rotates inward, and the head of the lock hook 13 is connected with the hanging part of the top cover 11;
[0063] ③ Close the safety piece 16.
[0064] The protective cover of the present application has the following beneficial effects:
[0065] (1) If there is no external force, the torsion spring keeps the lock hook 13 in a closing trend, and the torsion spring keeps the top cover 11 in an opening trend;
[0066] (2) The axes of the two ends of the safety member 16 are not coaxial, but slightly different, so that the safety member 16 will not rotate automatically when it is in any position without external force;
[0067] (3) At the joint between the lock hook 13 and the top cover 11, the upper surface of the lock hook 13 is designed to be a curved surface, and the lower surface of the top cover 11 is designed to be a flat surface (which can also be a curved surface). When the safety piece 16 is opened, there is no need to press the bottom of the lock hook 13. The top cover 11 can be directly locked by pressing down directly.
[0068] The protective cover of the present application can provide protection for the common joint of the oxygen supply tubes when the common joint of the oxygen supply tubes is not working, is easy to open and close, and can be automatically closed.
[0069] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
