DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 The utility model provides a technical solution: a water meter that can be sealed and dustproof, including a meter body 1 and a protective cover 4, connectors 2 are installed on both sides of the meter body 1, a dial 3 is installed on the top of the meter body 1, and the protective cover 4 is connected to one side of the meter body 1 through a rotating shaft.

[0024] A protrusion 5 is installed on one side of the protective cover 4, a first clamping block 6 is installed on the bottom of the protrusion 5, a fixed block 7 is sleeved on the outer side of the first clamping block 6, a connecting block 8 is installed on the bottom of the fixed block 7, a wedge block 9 is installed inside the connecting block 8 through a groove, a movable block 10 penetrating the connecting block 8 is connected to one side of the wedge block 9, a movable spring 11 is installed inside the movable block 10 through a groove, a second clamping block 12 penetrating the movable block 10 is connected to the bottom of the movable spring 11, a positioning block 13 is sleeved on the bottom of the second clamping block 12, a sealing rubber ring 14 is installed on one end of the protective cover 4 through the groove, and the fixed block 7 is installed on one side of the meter body 1.

[0025] In specific implementation, the sealed dust-proof water meter can be used in daily use by squeezing the second block 12 upward so that the bottom of the second block 12 moves out of the groove of the positioning block 13. If the second block 12 is not connected to the groove of the positioning block 13, the wedge block 9 can be pulled to one side so that the wedge block 9 shrinks into the groove of the connecting block 8. Then the protective cover 4 can be rotated to the top of the dial 3 through the rotating shaft. When the protective cover 4 is rotated to the top of the dial 3, the first block 6 at one end of the protrusion 5 will pass through the fixing block 7 through the through hole. At this time, the wedge block 9 is pushed in the reverse direction so that the wedge block 9 moves out of the groove of the connecting block 8 and squeezes the wedge block 9. Since the side of the wedge block 9 close to the first block 6 and the side of the first block 6 are both inclined structures, At this time, the wedge block 9 will squeeze the first clamping block 6, so that the first clamping block 6 drives the protective cover 4 to move in the direction of the dial 3 through the protrusion 5. At the same time, the wedge block 9 drives the second clamping block 12 to move to the top of the positioning block 13 through the movable block 10, and then releases the second clamping block 12. The second clamping block 12 will be reset by the movable spring 11, so that the second clamping block 12 is inserted into the groove of the positioning block 13. At this time, the wedge block 9 can be fixed. Through the cooperation of the wedge block 9 and the first clamping block 6, the protective cover 4 and the dial 3 can be tightly fitted, so that the dial 3 squeezes the sealing rubber ring 14 in the groove of the protective cover 4, causing the sealing rubber ring 14 to deform, thereby enhancing the sealing and dustproof effect of the dial 3 and preventing dust from entering the dial 3.

[0026] See also Figures 1 to 4 It can be seen that when the utility model is not in use, the protective cover 4 can be turned over onto the dial 3, and the sealing effect between the protective cover 4 and the dial 3 is enhanced by the cooperation between the wedge block 9 and the first clamping block 6.

[0027] A telescopic block 15 is installed inside the protective cover 4 through a groove, a pressure block 16 is arranged on one side of the telescopic block 15, one end of the pressure block 16 is connected to a pressure rod 17 that passes through the protective cover 4, a return spring 18 is installed between the end of the pressure block 16 away from the pressure rod 17 and the groove of the protective cover 4, a cleaning disk 19 is arranged between the telescopic block 15 and the groove of the protective cover 4, the telescopic block 15 forms a telescopic structure through the groove and the protective cover 4, and two groups of telescopic blocks 15 are symmetrically installed about the center line of the cleaning disk 19.

[0028] In specific implementation, when it is necessary to clean the surface of the dial 3, the pressure rod 17 can be squeezed so that the pressure rod 17 drives the pressure block 16 to move toward the inside of the protective cover 4, and the pressure block 16 releases the squeezing of the telescopic block 15. At the same time, the pressure block 16 squeezes the return spring 18 in the groove of the protective cover 4 to make it compressed. The pressure block 16 releases the squeezing of the telescopic block 15, and the telescopic block 15 can be squeezed into the groove of the protective cover 4 to shrink into the groove of the protective cover 4. The telescopic block 15 releases the limit on the cleaning disk 19, and the cleaning disk 19 can be removed from the inner wall of the protective cover 4. The surface of the cleaning disk 19 is made of cloth. The dial 3 can be cleaned by moving the cleaning disk 19 back and forth along the surface of the dial 3, so that the values ​​on the dial 3 are clearer.

[0029] After cleaning is completed, the cleaning disc 19 is installed to the inner wall of the protective cover 4. Since one side of the telescopic block 15 is a sloped structure, the cleaning disc 19 will squeeze the telescopic block 15 when installing the cleaning disc 19, so that the telescopic block 15 will retract into the groove of the protective cover 4 again, and squeeze the reset spring 18 through the pressure block 16. When the cleaning disc 19 is completely installed on the inner wall of the protective cover 4, the cleaning disc 19 releases the squeezing of the telescopic block 15, and the reset spring 18 will drive the pressure block 16 to reset, so that the pressure block 16 squeezes the telescopic block 15 from the groove of the protective cover 4. The cleaning disc 19 can be limited to the inner wall of the protective cover 4 through the telescopic block 15, so that it is convenient to remove the cleaning disc 19 to clean the dial 3.

[0030] See also Figure 1 and Figure 5 It can be seen that when the dial 3 needs to be cleaned, the cleaning disc 19 is removed from the inner wall of the protective cover 4, so as to facilitate cleaning the surface of the dial 3.

[0031] To sum up: when the utility model is used, the water inlet pipe and the water outlet pipe can be connected respectively at the connectors 2 on both sides of the meter body 1, and the connectors 2 are sealed to prevent water leakage at the connectors 2. Then, the faucet is turned on, and water flows from the water inlet pipe through the meter body 1 to the water outlet pipe, and the pointers and numbers in the dial 3 will change, thereby realizing the measurement of the water flow rate. This is the use feature of the sealable dust-proof water meter. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
