DETAILED DESCRIPTION

[0023] The following description is intended to disclose the present invention and enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0024] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0025] The present invention provides a high-safety gypsum top air outlet device, combined with Figures 1 to 6 The high-safety gypsum top air outlet device includes a base 1 arranged axially through, a ventilation pipe joint 2 arranged on the upper side of the base 1, and a baffle 4 arranged at the air outlet 3 on the lower side of the base 1. An air outlet gap 5 is formed between the outer periphery of the baffle 4 and the inner periphery of the air outlet 3. A magnetic structure is provided between the inner top surface of the lower side of the base 1 and the upper side surface of the baffle 4. The upper side surface of the baffle 4 is connected to the inner top surface of the lower side of the base 1 through the magnetic structure. It also includes a safety rope 6, one end of the safety rope 6 is connected to the inner top surface of the lower side of the base 1, and the other end of the safety rope 6 is connected to the upper side surface of the baffle 4. The length of the safety rope 6 is set so that the baffle 4 can be completely separated from the base 1.

[0026] Through the magnetic structure, when removing the cover 4, the base 1 and the cover 4 can be separated by pulling down slightly, and the safety rope 6 also has a certain length, which can make the cover 4 completely separated from the base 1. Figure 3 The figure shows the length of the safety rope 6. The removed blocking cover 4 can be hung below with the help of the safety rope 6. Of course, in the event of accidental drop, the safety rope 6 can also be used to hang the blocking cover 4.

[0027] In order to have better fixing strength, the upper side surface of the baffle cover 4 and the inner top surface of the lower side of the base 1 are provided with fixing screws 14 and connecting inserts 15. The connecting inserts 15 are embedded and fixed in the upper side surface of the baffle cover 4 and the inner top surface of the lower side of the base 1, and then the two ends of the safety rope 6 are fixed to the upper side surface of the baffle cover 4 and the inner top surface of the lower side of the base 1 respectively through the fixing screws 14.

[0028] In some embodiments, as Figure 3 、 5 As shown in , 6, the magnetic attraction structure includes a suspension rod 7 and a magnet 8 with corresponding positions. The suspension rod 7 and the magnet 8 are connected by magnetic force. The suspension rod 7 and the magnet 8 can be separated by overcoming the magnetic force. One of the suspension rod 7 and the magnet 8 is set on the inner top surface of the lower side of the base 1, and the other of the suspension rod 7 and the magnet 8 is set on the upper side of the cover 4.

[0029] Furthermore, the number of the suspension rods 7 and the number of the magnets 8 are multiple and are sequentially distributed along the inner periphery of the barrier cover 4. In this example, the number of the suspension rods 7 and the number of the magnets 8 are three and are evenly distributed along the inner periphery of the barrier cover 4.

[0030] In some embodiments, as Figure 3 As shown, the suspension rod 7 is a screw rod, and a nut 9 is provided on the inner top surface of the lower side of the base 1. The screw rod is threadedly connected to the nut 9. Through this threaded connection, the height of the screw rod relative to the base 1 can be adjusted. A magnet 8 is provided on the upper side of the cover 4, and the lower end of the screw rod is magnetically connected to the magnet 8. In this way, the height of the screw rod relative to the base 1 can be easily adjusted through the threaded connection. In this way, the height of the cover 4 relative to the base 1 can be changed, thereby achieving the purpose of conveniently adjusting the air outlet interval 5.

[0031] Of course, a fixed height setting structure is also possible, that is, when the upper end of the screw is threadedly connected to the nut 9 and screwed to the bottom, the nut 9 is set as a metal insert in the inner top surface of the lower side of the base 1, and a blind hole is formed in the inner top surface of the lower side of the base 1. Then, when the upper end of the screw is threadedly connected to the nut 9 and screwed to the bottom, the upper end of the screw and the inner bottom surface of the blind hole are abutted, thereby forming a fixed height setting. If it is a fixed setting, the air outlet space 5 will form a fixed flow cross-section.

[0032] Of course, other structures are also possible. For example, a nut 9 is provided on the upper side of the cover 4, and the screw is threadedly connected to the nut 9. Through this threaded connection, the screw can be adjusted in height relative to the cover 4. A magnet 8 is provided on the inner top surface of the lower side of the base 1, and the upper end of the screw is magnetically connected to the magnet 8. Of course, a fixed height setting as described above is also possible.

[0033] In order to facilitate disassembly and assembly and facilitate fixation, in some embodiments, as Figure 5 、 6 As shown, a guide hole 10 is provided at the installation position of the magnet 8 , and the suspension rod 7 is inserted through the guide hole 10 and magnetically connected to the magnet 8 .

[0034] In some embodiments, as Figure 3 As shown, the end portion of the suspension rod 7 that is magnetically connected to the magnet 8 is provided with a flat portion 11, which is used to expand the contact area with the magnet 8. In this way, a greater magnetic connection force can be provided, thereby facilitating a more reliable fixation of the barrier cover 4, thereby facilitating safety.

[0035] Furthermore, the suspension rod 7 is a bolt, which includes a screw portion and a head, and the head serves as a flat portion 11 .

[0036] In some embodiments, as Figure 2 、 3 As shown in FIG4 , the air outlet 3 is further provided with a damper 12, which is provided with a detachable damping block 13. The lower side of the damper 12 is located above the upper side of the cover 4. After the cover 4 is opened, the lower side of the damper 12 can be fully exposed. The air volume can be adjusted by disassembling the detachable damping block 13. Figure 4 As shown, three detachable damping blocks 13 have been removed. Combined with the disassembly and assembly scheme of the blocking cover 4 disclosed in the present invention, adjustment is very convenient, greatly reducing the operating burden and reducing the professional requirements of operation.

[0037] like Figure 3 、 4 As shown, two types of damping blocks 13 or damping plugs are provided, namely cylindrical damping plugs and special-shaped damping plugs, which can be partially retained or completely removed to adjust the air volume. In this example, the cross-sectional areas of the cylindrical damping plug and the special-shaped damping plug are set to be the same.

[0038] When understanding the present invention, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration is needed here.

[0039] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in the present disclosure should be included within the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
