[0025] Example:

[0026] See also Figure 1 and Figure 2 The embodiment of the utility model provides a protective mask, including a mask body 1, a strap and a connecting piece 3. The two ends of the mask body 1 are connected, one end of the mask body 1 is the wearing side and the cross section is triangular, which is conducive to fitting with the face; a fixing column 2 is arranged on the outside of the mask body 1, and at least two fixing columns 2 are provided, and each fixing column 2 is arranged at intervals. The connecting piece 3 connects the mask body 1 and the strap respectively, and at least two connecting pieces 3 are provided, and the fixing columns 2 and the connecting pieces 3 are connected one by one, and the strap is connected to all the connecting pieces 3. For example, there are two connecting pieces 3 and two fixing columns 2, and the two fixing columns 2 are distributed on the opposite sides of the mask body 1. The two connecting pieces 3 are respectively connected to the two fixing columns 2, and the two ends of the strap are respectively connected to the two connecting pieces 3, so that the protective mask can be fixed on the user through the strap. According to actual needs, three, four, etc. fixing columns 2 and connecting pieces 3 can be provided.

[0027] See also Figure 1 , Figure 2 and Figure 3 The fixing column 2 is provided with a limiting structure, and the connecting piece 3 is provided with a mounting hole 311 and a positioning hole 312. The mounting hole 311 is connected to the positioning hole 312. The positioning hole 312 is adapted to the fixing column 2, and the aperture of the positioning hole 312 is smaller than the aperture of the mounting hole 311. The fixing column 2 is inserted into the positioning hole 312 through the mounting hole 311, and when the fixing column 2 is inserted into the positioning hole 312, the connecting piece 3 is restricted between the limiting structure and the cover body 1.

[0028] Since the positioning hole 312 is compatible with the fixing column 2, and the aperture of the positioning hole 312 is smaller than the aperture of the mounting hole 311, during the connection process between the connecting piece 3 and the cover body 1, the fixing column 2 is first installed in the mounting hole 311, and then the connecting piece 3 is moved to make the fixing column 2 installed in the positioning hole 312. At this time, the connecting piece 3 is restricted between the limiting structure and the cover body 1, completing the connection between the connecting piece 3 and the cover body 1, and the strap can be connected to the cover body 1 through the connecting piece 3, so that the strap is fixed to the cover body 1 in a purely manual manner, without a magnetic structure, and will not affect patients with pacemakers installed, thereby expanding the scope of application of the protective mask, and the connection structure between the strap and the cover body 1 is simple, and the manufacturing cost is lower.

[0029] It should be understood that, since the positioning hole 312 is connected to the mounting hole 311, the fixing column 2 can be moved from the mounting hole 311 to the positioning hole 312, thereby facilitating the connection and fixation between the connecting piece 3 and the cover body 1. The binding strap can be fixed to the connecting piece 3 before the connecting piece 3 is fixed to the cover body 1, or it can be fixed to the connecting piece 3 after the connecting piece 3 is fixed to the cover body 1.

[0030] See also Figure 2 and Figure 3In some embodiments, the limiting structure includes a limiting cap 21 fixed to the end of the fixing column 2 away from the cover body 1, and the diameter of the positioning hole 312 is smaller than the outer diameter of the limiting cap 21, so that after the fixing column 2 is inserted into the positioning hole 312, the limiting cap 21 can prevent the connecting piece 3 from axially separating from the cover body 1, thereby achieving the fixation between the connecting piece 3 and the cover body 1; the diameter of the mounting hole 311 is larger than the outer diameter of the limiting cap 21, which facilitates the fixing column 2 to be installed in the mounting hole 311.

[0031] In other embodiments, the limiting structure may be a limiting block fixed on the peripheral side of the fixed column 2, and there are multiple limiting blocks, which are spaced apart along the circumferential direction, and the connecting piece 3 is limited between the limiting block and the cover body 1.

[0032] See also Figure 1 and Figure 3 The mounting holes 311 and the positioning holes 312 are continuously distributed along the length direction of the connecting piece 3, and the positioning hole 312 of the mounting holes 311 and the positioning holes 312 is closer to the end of the connecting piece 3 connected to the fixing column 2, so that after the fixing column 2 is installed in the positioning hole 312, the connecting piece 3 will be arranged vertically under the action of gravity, which can prevent the fixing column 2 from having a tendency to move toward the mounting hole 311, which is conducive to improving the connection firmness between the cover body 1 of the connecting piece 3. The fixing column 2 and the positioning hole 312 are interference-fitted, which prevents the fixing column 2 from easily moving into the mounting hole 311 after the connecting piece 3 is subjected to force.

[0033] It should be noted that, in some embodiments, the mounting holes 311 and the positioning holes 312 may also be continuously distributed along the width direction of the connecting piece 3 .

[0034] See also Figure 2 and Figure 3 The connecting piece 3 is provided with a notch 313, which is connected to the positioning hole 312, and the notch 313 penetrates the opposite two side surfaces of the connecting piece 3 in the thickness direction of the connecting piece 3, so that the connecting piece 3 can be pried by the notch 313 so that the connecting piece 3 can be elastically expanded in the radial direction, so that the diameter of the positioning hole 312 increases to be larger than the outer diameter of the limiting cap 21, so that the connecting piece 3 can be separated from the cover body 1, and it is convenient to disassemble the connecting piece 3; and when the connecting piece 3 is not pried, the connecting piece 3 will elastically shrink in the radial direction, and the diameter of the positioning hole 312 will return to the initial size. It should be understood that the provision of the notch 313 can make the connecting piece 3 elastic, so that the connecting piece 3 can be elastically expanded or elastically contracted in the radial direction to change the diameter size of the positioning hole 312.

[0035] See also Figure 3Furthermore, the portion of the connecting piece 3 surrounding the positioning hole 312 is symmetrically arranged with the length extension direction of the notch 313 as the symmetry axis, which is convenient for bending the connecting piece 3 and at the same time makes the positioning hole 312 expand or shrink toward both sides, which is conducive to realizing the elastic recovery of the connecting piece 3 to the initial state. According to actual needs, the position of the notch 313 can be set at any position of the portion of the connecting piece 3 surrounding the positioning hole 312, for example, the notch 313 is biased to the left or right.

[0036] See also Figure 2 and Figure 3 The connecting piece 3 includes a first connecting portion 31 and a second connecting portion 32 fixed to the first connecting portion 31. The first connecting portion 31 is connected to the fixing column 2, and the second connecting portion 32 is connected to the binding strap. The second connecting portion 32 is tilted relative to the first connecting portion 31, so that there is a large gap between the second connecting portion 32 and the cover body 1, which is convenient for connecting and fixing the binding strap to the second connecting portion 32; at the same time, it is also beneficial to ensure that the first connecting portion 31 and the cover body 1 are tightly fitted together.

[0037] It should be noted that the portion of the connecting piece 3 surrounding the positioning hole 312 can be arranged to move axially between the limiting cap 21 and the cover body 1, that is, the connecting piece 3 can move up and down between the limiting cap 21 and the cover body 1, so that the strap has a certain movable space, which is convenient for wearing the protective mask on the user through the strap; the portion of the connecting piece 3 surrounding the positioning hole 312 can also be arranged to be inserted between the limiting cap 21 and the cover body 1, which can improve the connection firmness between the connecting piece 3 and the cover body 1.

[0038] See also Figure 2 and Figure 3 The connection between the first connection part 31 and the second connection part 32 is an arc-shaped transition, so that the second connection part 32 is tilted relative to the first connection part 31; a connection hole 321 is provided on the second connection part 32, and the strap is connected to the second connection part 32 through the connection hole 321, specifically, the strap is tied and fixed to the second connection part 32 through the connection hole 321.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
