DETAILED DESCRIPTION

[0021] To make the purposes, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are some but not all of the embodiments of the present disclosure. Based on the described embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present disclosure.

[0022] Please refer to Figure 1-Figure 3 A carbon emission metering device convenient to adjust, comprising: a metering device body 1, the top of the metering device body 1 is fixedly connected with an air inlet pipe 2, the top of the air inlet pipe 2 is slidably sleeved with a protective cover 3, the protective cover 3 is installed with a filter screen 5, the outer side of the air inlet pipe 2 is fixedly sleeved with a wedge ring 6, the outer side of the air inlet pipe 2 is slidably provided with a double-sided wedge ring 7 located below the wedge ring 6, the inner side wall of the protective cover 3 is provided with two radially sliding wedge blocks 8 arranged symmetrically, the protective cover 3 is internally provided with a screw hole 34, the wedge block 8 is slidably arranged in the screw hole 34, the outlet position of the screw hole 34 is threadedly connected with a second screw 82, a second spring 81 is arranged between the wedge block 8 and the second screw 82, one end of the second spring 81 is fixedly connected to the wedge block 8, the other end of the second spring 81 is fixedly connected to the second screw 82, the second screw 82 is threadedly connected in the screw hole 34, when the wedge block 8 is located between the wedge ring 6 and the double-sided wedge ring 7, the air inlet pipe 2 and the protective cover 3 are locked.

[0023] Specifically, the wedge ring 6 is a wedge ring with an upward bevel, the wedge 8 is a wedge with a downward bevel, and the double-sided wedge ring 7 is a wedge ring with bevels on both the upper and lower sides. First, the protective cover 3 is put on the outside of the air inlet pipe 2, and the protective cover 3 is pressed downward for the first time. The bevel of the wedge 8 contacts the bevel of the wedge ring 6 to generate an extrusion force, so that the wedge 8 overcomes the elastic force of the second spring 81 and retracts into the screw hole 34. As the protective cover 3 continues to move downward, the wedge 8 has slid past the area where the wedge ring 6 is located. Under the elastic force of the second spring 81, the wedge 8 slides out of the screw hole 34. At this time, the wedge 8 is located below the wedge ring 6, so that the protective cover 3 cannot slide away from the air inlet pipe 2; the protective cover 3 is pressed a second time, so that the bevel of the wedge 8 contacts the double-sided wedge The upper inclined surface of the double-sided wedge ring 7 contacts and generates an extrusion force. After overcoming the elastic force of the second spring 81, the wedge block 8 moves along the outer side of the double-sided wedge ring 7 until the wedge block 8 contacts the side of the lower half of the double-sided wedge ring 7, pulling the protective cover 3 outward, so that the protective cover 3 drives the double-sided wedge ring 7 to slide upward along the outer side of the air inlet pipe 2 through the wedge block 8 until the top of the double-sided wedge ring 7 contacts the bottom of the wedge ring 6. After the force of pulling the protective cover 3 outward overcomes the elastic force of the second spring 81, the wedge block 8 retracts into the screw hole 34, thereby quickly pulling out the protective cover 3, so that the wedge block 8 quickly passes through the area where the wedge ring 6 is located, that is, the locking state of the protective cover 3 and the air inlet pipe 2 is released, and the filter 5 inside the protective cover 3 can be replaced.

[0024] Furthermore, an inner cover ring 31 is coaxially arranged inside the protective cover 3 , the inner cover ring 31 is inserted into the air inlet pipe 2 , and the filter 5 is installed on the bottom of the inner cover ring 31 by a first screw 51 .

[0025] Specifically, refer to Figure 2 By fixing the inner cover ring 31 in the protective cover 3 and inserting the inner cover ring 31 into the air inlet pipe 2, the sliding of the protective cover 3 on the air inlet pipe 2 is guided, making the protective cover 3 more stable when sliding. By installing the filter screen 5 at the bottom of the inner cover ring 31, the filter screen 5 is deeply inserted into the air inlet pipe 2, which plays a good protective role for the filter screen 5. The filter screen 5 completely covers the inner cover ring 31 to prevent dust from entering the metering device body 1.

[0026] Furthermore, a first spring 4 is sleeved on the outside of the inner cover ring 31 , the top of the first spring 4 is fixedly connected to the inner wall of the protective cover 3 , and the bottom of the first spring 4 is fixedly connected to a gasket 41 that is slidably sleeved on the outside of the inner cover ring 31 .

[0027] Specifically, refer to Figure 2, through the setting of the first spring 4, the worker feels better when pressing the protective cover 3, when the protective cover 3 is in the locking state with the air inlet pipe 2, under the elastic force of the first spring 4, the protective cover 3 has a tendency to slide outward relative to the air inlet pipe 2, so that the top of the wedge block 8 is tightly pressed on the bottom of the wedge-shaped ring 6, so that the protective cover 3 and the air inlet pipe 2 cannot be relatively displaced, so that the device is more stable, and when the protective cover 3 is pressed for the second time to release the locking relationship between the protective cover 3 and the air inlet pipe 2, under the elastic force of the first spring 4, the protective cover 3 will be directly able to pop out of the air inlet pipe 2, without the worker needing to quickly pull the protective cover 3 outward, improving the stability of the device.

[0028] Further, the top of the protective cover 3 is provided with a plurality of air inlet holes 32, and the air inlet holes 32 are all located within the diameter range of the inner cover ring 31.

[0029] Specifically, the air inlet hole 32 is an air inlet, which can intercept large-volume garbage and prevent garbage from entering the device, and the air inlet hole 32 is arranged within the diameter range of the inner cover ring 31, so that gas cannot enter other areas of the device.

[0030] Further, the outer side of the air inlet pipe 2 is fixedly connected with two symmetrically arranged protruding blocks 21, and the inner side wall of the bottom of the protective cover 3 is provided with a sliding groove 33 for the sliding of the protruding blocks 21.

[0031] Specifically, the protruding block 21 and the sliding groove 33 are provided, so that the protective cover 3 can only slide along the axis direction when sliding outside the air inlet pipe 2, avoiding rotation of the protective cover 3 relative to the air inlet pipe 2, and ensuring that the installation and disassembly of the protective cover 3 are more stable.

[0032] Further, the maximum outer diameter of the double-sided wedge-shaped ring 7 is greater than the maximum outer diameter of the wedge-shaped ring 6.

[0033] Specifically, the maximum outer diameter of the double-sided wedge-shaped ring 7 is greater than the maximum outer diameter of the wedge-shaped ring 6, which can further improve the protective cover 3 when being pressed twice, so as to ensure that the protective cover 3 slides away from the air inlet pipe 2, and effectively offset the error caused by the reduction of the ejection speed of the protective cover 3 due to the aging of the first spring 4.

[0034] In the utility model, reference Figures 1 to 3, first, put the protective cover 3 on the outside of the air inlet pipe 2, press the protective cover 3 downward for the first time, the protective cover 3 overcomes the elastic force of the first spring 4 and slides downward, then the inclined surface of the wedge block 8 contacts the inclined surface of the wedge ring 6 to generate an extrusion force, so that the wedge block 8 retracts into the screw hole 34 after overcoming the elastic force of the second spring 81. As the protective cover 3 continues to move downward, the wedge block 8 has slid past the area where the wedge ring 6 is located. Under the elastic force of the second spring 81, the wedge block 8 slides out of the screw hole 34. At this time, the wedge block 8 is located below the wedge ring 6, and under the elastic force of the first spring 4, the protective cover 3 slides upward, and the top of the wedge block 8 squeezes the bottom of the wedge ring 6, so that the protective cover 3 cannot slide away from the air inlet pipe 2; press the protective cover 3 for the second time, after overcoming the elastic force of the first spring 4, the protective cover 3 continues to slide downward, so that the wedge block The inclined surface of 8 contacts the upper inclined surface of the double-sided wedge ring 7 to generate an extrusion force. After overcoming the elastic force of the second spring 81, the wedge block 8 moves along the outer side of the double-sided wedge ring 7 until the wedge block 8 contacts the side of the lower half of the double-sided wedge ring 7 and stops pressing the protective cover 3. Under the elastic force of the first spring 4, the protective cover 3 drives the double-sided wedge ring 7 to slide upward along the outer side of the air inlet pipe 2 through the wedge block 8 until the top of the double-sided wedge ring 7 contacts the bottom of the wedge ring 6. After the elastic force of the first spring 4 pushing the protective cover 3 upward overcomes the elastic force of the second spring 81, the wedge block 8 retracts into the screw hole 34. Under the elastic force of the first spring 4, the wedge block 8 quickly passes through the area where the wedge ring 6 is located, that is, the locking state of the protective cover 3 and the air inlet pipe 2 is released, and the filter 5 inside the protective cover 3 can be replaced.

[0035] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
