[0051] Example 1

[0052] This embodiment provides a face cover whose flip cover can be quickly locked and unlocked by sliding against the face cover body, improving operational convenience. Furthermore, unlocking does not require disassembling parts, thus improving the reliability of the face cover's function.

[0053] Specifically, such as Figures 1-6 As shown, the face cover includes a face cover body 100 and a flip cover 200. The upper surface 101 of the face cover body 100 has a connecting portion 110 and a first locking portion 120. The flip cover 200 has a rotating portion 210 and a second locking portion 220. The rotating portion 210 is located at one end of the flip cover 200 and is movably connected to the connecting portion 110, allowing the flip cover 200 to rotate and slide relative to the face cover body 100. When the flip cover 200 is closed, sliding relative to the face cover body 100 allows the second locking portion 220 to engage or disengage from the first locking portion 120.

[0054] It is understandable that the flip cover 200 is placed on the face cover body 100 in the closed state to cover the accessories on the face cover body 100; when the flip cover 200 is open, it is set at an angle to the face cover body 100, at which time the accessories can be exposed, making it convenient to repair or replace the accessories.

[0055] Therefore, when the cover is working normally, the flip cover 200 is in the closed state. When it is necessary to repair or replace the accessories on the cover body 100, the flip cover 200 can be pushed by hand to slide until the second locking part 220 separates from the first locking part 120. At this time, the flip cover 200 is unlocked from the cover body 100, and the flip cover 200 can be rotated by hand to open it, and then the accessories can be repaired or replaced. After the accessories are repaired or replaced, the flip cover 200 can be rotated by hand to the closed state, and then the flip cover 200 can be pushed to slide in the opposite direction, so that the second locking part 220 engages with the first locking part 120, thereby locking the flip cover 200 to the cover body 100 to ensure the reliability of the flip cover 200 in protecting the accessories.

[0056] The face cover provided in this embodiment has a flip cover 200 that can be quickly locked and unlocked by sliding with the face cover body 100, which reduces the difficulty of operation. Furthermore, unlocking does not require disassembling parts, thus avoiding the loss of parts and improving the reliability of the face cover.

[0057] Optionally, the direction of the rotation axis of the flip cover 200 can be perpendicular to or the same as the sliding direction of the flip cover 200.

[0058] For example, see [link to previous article] Figure 1 , Figures 4-7 In one possible embodiment, the connecting portion 110 includes connecting blocks 111 disposed on opposite sides of the upper surface 101, with elongated grooves 112 provided on the opposite surfaces of the two connecting blocks 111. The rotating portion 210 includes rotating shafts 211 disposed on opposite side walls of the flip cover 200, with each rotating shaft 211 corresponding to one of the elongated grooves 112, and each rotating shaft 211 being movably installed within its corresponding elongated groove 112. See also... Figure 1 The rotating shaft 211 can slide along the extension direction of the long groove 112, and the extension direction of the long groove 112 ( Figure 1 and Figure 4 (in the direction shown by the Y-axis) and the extension direction of the rotation axis 211 ( Figure 1 and Figure 4 The direction indicated by the X-axis is perpendicular to the direction of rotation of the flip cover 200 (the extension direction of the rotating shaft 211). With this configuration, the direction of rotation of the flip cover 200 (the extension direction of the long groove 112) is perpendicular to the sliding direction of the flip cover 200. The rotation and sliding of the flip cover 200 relative to the cover body 100 are achieved through the cooperation of the long groove 112 and the rotating shaft 211. This design is simple, easy to manufacture and assemble, and has high operational reliability.

[0059] In another possible embodiment, such as Figure 2As shown, the connecting portion 110 includes connecting blocks 111 arranged on opposite sides of the upper surface 101, and the connecting blocks 111 are provided with connecting holes 113. The rotating portion 210 includes rotating shafts 211 arranged on opposite side walls of the flip cover 200, and the rotating shafts 211 are arranged in one-to-one correspondence with the connecting holes 113. Furthermore, each rotating shaft 211 is slidingly installed in the connecting hole 113 in the direction (indicated by the X-axis) in which the connecting hole 113 extends, and the direction (indicated by the X-axis) in which the connecting hole 113 extends is the same as the direction (indicated by the X-axis) in which the rotating shaft 211 extends. In this way, the direction in which the rotating shaft of the flip cover 200 is located (the direction in which the rotating shaft 211 extends) is the same as the sliding direction of the flip cover 200 (the direction in which the connecting hole 113 extends). The rotation and sliding of the flip cover 200 relative to the face cover body 100 are realized through the cooperation of the connecting hole 113 and the rotating shaft 211, and the structure is simple, easy to process and assemble, and has high working reliability. Figure 2 Figure 2 Alternatively, continuing to refer to Figure 2 and , the two connecting blocks 111 are arranged opposite to each other in the width direction of the upper surface 101. In this arrangement, the flip cover 200 is flipped from one end in the length direction of the upper surface 101. Continuing to refer to

[0060] , the two connecting blocks 111 can also be arranged opposite to each other in the length direction of the upper surface 101. In this arrangement, the flip cover 200 is flipped from one end in the width direction of the upper surface 101. Figure 1 Figure 2 Alternatively, continuing to refer to Figure 3 , and

[0061] , the first clamping portion 120 includes L-shaped locking pieces 121 arranged on the upper surface 101, and the L-shaped locking pieces 121 and the upper surface 101 enclose locking grooves 122. The second clamping portion 220 includes locking tongues 221 arranged on the flip cover 200, and the locking tongues 221 can be clamped or separated from the locking grooves 122. The locking and unlocking of the face cover body 100 and the flip cover 200 are realized through the cooperation of the locking grooves 122 and the locking tongues 221, and the structure is simple, easy to process, and has high locking reliability. Figure 4 Figure 6 Further, continuing to refer to Figure 7 , a notch 123 is arranged on the plate surface opposite to the L-shaped locking piece 121 and the upper surface 101. Through the arrangement of the notch 123, the deformation amount of the plate surface can be increased to facilitate the clamping of the locking groove 122 and the locking tongue 221.

[0062] Alternatively, continuing to refer to Figure 4 , the first clamping portion 120 includes L-shaped locking pieces 121 arranged on the upper surface 101, and the L-shaped locking pieces 121 and the upper surface 101 enclose locking grooves 122. The second clamping portion 220 includes locking tongues 221 arranged on the flip cover 200, and the locking tongues 221 can be clamped or separated from the locking grooves 122. The locking and unlocking of the face cover body 100 and the flip cover 200 are realized through the cooperation of the locking grooves 122 and the locking tongues 221, and the structure is simple, easy to process, and has high locking reliability.

By arranging two pairs of L-shaped locking pieces 121 and locking tongues 221, the clamping effect between the cover 200 and the face cover body 100 can be improved, and the reliability of the cover 200 in closing can be improved.

[0064] Of course, in other embodiments, the number and arrangement of the L-shaped locking pieces 121 can be other arrangements, which can be arranged according to actual needs, and the present application does not make specific limitations.

[0065] Embodiment Two

[0066] The face cover provided in the embodiment is generally the same as that of the first embodiment, and only improved on the basis of the first embodiment. Therefore, only the differences between the two embodiments are described, and the same structures of the two embodiments are not described again. In the embodiment, the same or corresponding technical features of the first embodiment are denoted by the same reference numerals.

[0067] As shown in Figures 8-14 , in the embodiment, the cover 200 is provided with a knob 300, which can cooperate with the face cover body 100 to push the cover 200 to slide, so that the second clamping part 220 is clamped or separated from the first clamping part 120.
