DETAILED DESCRIPTION
[0033] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the underwater mask buckle structure provided by the embodiment of the utility model includes a first buckle 110 arranged on the mask body 100, and the first buckle 110 is adapted to the lower box body 300; the first buckle 110 is provided with an anti-disassembly sealing hole 101.
[0037] The mask body 100 is connected to the lower box body 300 by the first fastener 110, so there is no need to open a bolt mounting hole on the mask body 100, which not only saves the bolt tightening operation, but also eliminates the need to use a plug cover to seal the bolt mounting hole to trim the surface of the mask body 100, thereby simplifying the assembly process and reducing material costs.
[0038] In the embodiment of the utility model, the first fastener 110 extends along the first direction and is used to be inserted into the lower box body 300 along the first direction; the anti-disassembly seal hole 101 passes through the first fastener 110 along the first direction. When the first fastener 110 is inserted into the slot 301 of the lower box body 300, the anti-disassembly seal hole 101 can be used for lead sealing or plastic sealing, thereby completely sealing the first fastener 110 to prevent users from disassembling it privately. In addition, by applying a seal through the anti-disassembly seal hole 101 set on the first fastener 110, compared with the use of bolts to fix the mask body 100, which requires the use of special bolts with openings for lead sealing, the manufacturing cost is lower, and the integrated design of the first fastener 110 and the anti-disassembly seal hole 101 is realized, and the structure is more compact.
[0039] like Figure 4 As shown, the first latch 110 has a first protrusion 111 ; when the first latch 110 is latched on the lower box body 300 , the first protrusion 111 abuts against the lower box body 300 to prevent the first latch 110 from loosening relative to the lower box body 300 .
[0040] In this embodiment, the first latch 110 passes through the slot 301 from top to bottom, and the first protrusion 111 can be configured with an angle that tilts inward from top to bottom, so that the first protrusion 111 can smoothly pass through the slot 301 when the first latch 110 passes through the slot 301. When the first latch 110 is latched to the lower box body 300, the first protrusion 111 is located below the slot 301, and the top surface of the first protrusion 111 abuts against the lower box body 300, thereby preventing the first latch 110 from falling out of the slot 301.
[0041] In a preferred embodiment, the tamper-evident seal hole 101 is located on the inner side of the first protrusion 111. After a lead seal or a plastic seal is applied in the tamper-evident seal hole 101, the seal structure has a supporting effect on the first fastener 110, thereby preventing the first protrusion 111 from being squeezed inward, thereby improving the stability of the first fastener 110 being snapped into the slot 301.
[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the underwater mask buckle structure also includes: a second buckle 120 arranged on the mask body 100; the second buckle 120 is spaced apart from the first buckle 110, and the second buckle 120 is adapted to the lower box body 300.
[0043] The first fastener 110 is fastened to the slot 301, and the second fastener 120 is fastened to the fastening portion 302 of the lower box body 300, thereby improving the stability of the mask body 100 relative to the lower box body 300. In this embodiment, the slot 301 can be arranged on one side of the lower box body 300, and the fastening portion 302 can be arranged on the other side of the lower box body 300, and the two side surfaces have an angle or are arranged opposite to each other, so that the first fastener 110 and the second fastener 120 work together to ensure that the mask body 100 is firmly positioned relative to the lower box body 300.
[0044] In this embodiment, the second fastener 120 is provided with a groove cavity 121 and a second protrusion 122 located at the bottom of the groove cavity 121; when the second fastener 120 is engaged with the lower box body 300, the second protrusion 122 abuts against the lower box body 300 to prevent the second fastener 120 from loosening relative to the lower box body 300.
[0045] In an optional implementation, processes such as glue filling and plastic sealing may be performed in the groove cavity 121 to reinforce the connection of the second fastener 120, thereby also producing an anti-private disassembly effect.
[0046] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the water meter provided by the embodiment of the utility model includes: a mask body 100, a middle box body 200 and a lower box body 300, the mask body 100 is configured with the water surface mask snap-on structure described in the above-mentioned embodiment; the middle box body 200 is installed on the lower box body 300; the mask body 100 covers the middle box body 200, and the mask body 100 is snap-connected with the lower box body 300.
[0047] Specifically, the middle box body 200 and the lower box body 300 can be fixed by bolt connection, and the mask body 100 and the lower box body 300 are snap-connected, so there is no need to set bolt mounting holes on the mask body 100, and the bolt tightening and bolt mounting hole sealing processes in assembly can be omitted, and the assembly efficiency of the water meter is higher. In addition, a first screw hole position 303 can be set on the lower box body 300, and a second screw hole position 401 opposite to the first screw hole position 303 can be set on the base meter 400. By installing screws and making them match the first screw hole position 303 and the second screw hole position 401, the lower box body 300 can be firmly connected to the base meter 400.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
