Description

[Technical Field]

[0001] This utility model relates to the field of mechanical seal technology, specifically a front corrugated sealing cover. [Background Technology]

[0002] Modern bellows mainly utilizes a fan to generate negative pressure, causing air to be drawn in through the inlet, pressurized, and then discharged through the outlet, thus forming airflow. It is generally composed of a fan, a housing, inlet and outlet, a transmission device, and seals. Among them, the seals are key components used to seal the bellows, prevent gas leakage, and ensure the normal operation of the bellows.

[0003] For example, Chinese patent application CN218818125U discloses a sealing assembly, including a first sealing member having a first sealing surface and a sealing protrusion extending along the extension direction of the first sealing member, and the sealing protrusion having a first engaging portion; and a second sealing member having a second sealing surface opposite to the first sealing surface and a sealing groove recessed into the second sealing surface, the sealing groove extending along the extension direction of the second sealing member, the sealing protrusion being insertable into the sealing groove, and the sealing groove having a second engaging portion adapted to the first engaging portion.

[0004] However, when this sealing component is used, the sealing effect is not ideal, and gas leakage is prone to occur, which affects the working efficiency and stability of the bellows. It lacks sufficient adaptability and durability when facing changes in internal pressure and mechanical vibrations of the bellows, and is easily damaged, requiring frequent replacement, which increases the cost of use and maintenance workload.

[0005] Based on this, the present invention designs a front corrugated sealing cover to solve the above problems. [Utility Model Content]

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a front corrugated sealing cover.

[0007] To achieve the above objectives, a front corrugated sealing cover is designed, including a sealing element;

[0008] The sealing element includes a sealing connection assembly and an elastic buffer assembly for sealing the front side of the bellows;

[0009] The elastic cushioning assembly includes a cushioning cover, which is installed on the upper end of the sealing connection assembly, and the upper middle part of the cushioning cover is configured with a V-shaped corrugated structure.

[0010] Furthermore, the left and right sides of the buffer cover are symmetrical and are provided with an inclination angle A of 6.5°. The front of the buffer cover is inclined with an inclination angle B of 4.1°. The rear of the buffer cover is inclined from top to bottom and outward. The height of the buffer cover is 17.65mm.

[0011] Furthermore, the V-shaped corrugated structure is symmetrical from left to right and has an included angle C of 123°, and the depth of the V-shaped corrugated structure is 6.9 mm.

[0012] Furthermore, the upper left and right sides of the buffer cover are provided with second mounting holes, which are elliptical in shape.

[0013] Furthermore, darkrooms are fixedly installed on the left and right sides of the buffer cover, and the darkrooms protrude outwards with a height of 9.98mm.

[0014] Furthermore, the sealing connection assembly includes an annular outer ring, and a plurality of first mounting holes are provided on the outer side of the annular outer ring. The plurality of first mounting holes are evenly distributed, and a buffer cover is fixedly installed on the upper end of the annular outer ring.

[0015] Furthermore, the annular outer ring is elliptical in shape, with a length of 62mm, a width of 52mm, and a height of 1.5mm, and the first mounting hole is a threaded hole with a diameter of 3.5mm.

[0016] Furthermore, an adhesive element is also installed on the inner side of the annular outer ring. The adhesive element includes a sealing strip, which is annular and snaps onto the inner side of the annular outer ring.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] (1) The present invention, through the setting of the V-shaped corrugated structure, not only provides good elasticity, but also adapts to the pressure changes and mechanical vibration inside the bellows, thereby enhancing the sealing effect and extending the service life;

[0019] (2) This utility model reduces resistance by setting the slope of the buffer cover, avoids the airflow from directly impacting the bellows, and reduces vibration and noise. By setting the dark chamber, the sealing surface is isolated from the external environment, reducing wear caused by friction or particle intrusion. At the same time, the protruding design can also compensate for elasticity and balance pressure, improving reliability and durability. By setting the sealing strip and V-groove, the greater the wind pressure when the bellows is running, the tighter the sealing strip and the connection will fit, thereby improving the sealing effect.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 Front corrugated sealing cover, including seal 1;

[0029] The sealing element 1 includes a sealing connection assembly 11 and an elastic buffer assembly 12 for sealing the air box installed on the front side;

[0030] The elastic cushioning assembly 12 includes a cushioning cover 121, which is installed on the upper end of the sealing connection assembly 11. The upper middle part of the cushioning cover 121 is configured with a V-shaped corrugated structure 122, and the cushioning cover 121 is made of rubber material.

[0031] When the front corrugated sealing cover is in normal use, it is installed with the air box or related components through the sealing connection assembly 11. When the pressure inside the air box changes or there is mechanical vibration, the buffer cover 121 is subjected to force, causing the V-shaped corrugated structure 122 to deform, thereby buffering and diluting the pressure. The V-shaped corrugated structure 122 not only provides good elasticity, but also adapts to the pressure changes and mechanical vibration inside the air box, thereby enhancing the sealing effect and extending the service life.

[0032] The buffer cover 121 is symmetrical on the left and right sides and is provided with an inclination angle A of 6.5°. The front of the buffer cover 121 is inclined with an inclination angle B of 4.1°. The rear of the buffer cover 121 is inclined from top to bottom and outward. The height of the buffer cover 121 is 17.65mm.

[0033] The V-shaped corrugated structure 122 is symmetrical from left to right and has an included angle C of 123°. The depth of the V-shaped corrugated structure 122 is 6.9 mm.

[0034] The upper left and right sides of the buffer cover 121 are provided with second mounting holes 123, which are elliptical in shape.

[0035] Darkrooms 124 are also fixedly installed on the left and right sides of the buffer cover 121. The darkrooms 124 protrude outwards and have a height of 9.98mm.

[0036] The sealing connection assembly 11 includes an annular outer ring 111, and a plurality of first mounting holes 112 are provided on the outer side of the annular outer ring 111. The plurality of first mounting holes 112 are evenly distributed, and a buffer cover 121 is fixedly installed on the upper end of the annular outer ring 111.

[0037] The annular outer ring 111 is elliptical in shape, with a length of 62mm, a width of 52mm, and a height of 1.5mm. The first mounting hole 112 is a threaded hole with a diameter of 3.5mm.

[0038] like Figure 5 and Figure 6 As shown, an adhesive component 2 is also installed on the inner side of the annular outer ring 111. The adhesive component 2 includes a sealing strip 21, which is annular and is snapped onto the inner side of the annular outer ring 111.

[0039] The outer side of the sealing strip 21 is provided with a V-groove 22, and the inner side of the annular outer ring 111 is provided with an annular groove to cooperate with the sealing strip 21 and the V-groove 22.

[0040] When the front corrugated sealing cover is in normal use, it is fixedly connected to the air box or related components using bolts through the first mounting hole 112, and then fixedly connected using bolts through the second mounting hole 123. When the air box is running normally, the airflow flows along the inclined surface around the buffer cover 121, and will not directly impact the V-shaped corrugated structure 122. The pressure of the airflow on the buffer cover 121 causes the annular outer ring 111 to be subjected to a force away from the air box. The annular outer ring 111 compresses the sealing strip 21, and the V-shaped groove 22 of the sealing strip 21 deforms, causing the sealing strip 21 to contact the annular outer ring 111. The closer fit, the inclined design of the buffer cover 121 reduces resistance and prevents direct impact of airflow on the bellows, while also reducing vibration and noise. The dark chamber 124 isolates the sealing surface from the external environment, reducing wear caused by friction or particulate intrusion. The protruding design also compensates for elasticity and balances pressure, improving reliability and durability. The sealing strip 21 and V-groove 22 ensure that when the bellows is running, the greater the air pressure, the tighter the sealing strip 21 and the annular outer ring 111 will fit, thereby improving the sealing effect.
