Detailed Description
In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
As shown in fig. 2 to 4, an embodiment of the present invention provides a sealing ring, which includes a body section 1 and a first deformation section 11 disposed at a lower end of the body section 1, where the first deformation section 11 is used for abutting against a product 3 to be measured and forming a sealing surface with the product 3 to be measured; in the direction away from the body section 1, the first deformation section 11 has an increasing inner diameter, an increasing outer diameter and a decreasing thickness.
The utility model discloses a sealing washer is applicable to in the sealed check out test set that reveals, installs the sealing washer on the sealing washer installation piece in the sealed check out test set that reveals.
The sealing ring provided by the embodiment of the utility model has good sealing performance and simple structure and is suitable for batch production; when the sealing leakage detection equipment is used for carrying out sealing detection on the product 3 to be detected, the sealing ring of the utility model can not generate marks on the surface of the product 3 to be detected or crush the product to be detected while sealing; through the lower extreme at body section 1 sets up the internal diameter increase, the external diameter increases, first deformation section 11 that thickness diminishes, make the sealing washer need not like current O type sealing washer 4, support tight product 3 that awaits measuring in order to increase the leakproofness through applying external force, but can utilize the sealed negative pressure of revealing the check out test set self production, make first deformation section 11 warp, the inner wall of first deformation section 11 is from supreme deformation gradually down to with 3 surface laminating of product 3 that awaits measuring in order to reach encapsulated situation, owing to need not to push down whole sealing washer, make product 3 that awaits measuring can not produce the impression because of receiving the extrusion force.
In one embodiment, as shown in fig. 2 and 3, the first deforming portion 11 is tapered as a whole, and the inner surface 11a of the first deforming portion 11 is a flat tapered surface. Through the internal surface 11a design for smooth conical surface with first deformation section 11 for when outside atmospheric pressure acted on first deformation section 11, the internal surface 11a of first deformation section 11 can closely contact with the product 3 that awaits measuring, reaches better sealed effect.
In an embodiment, as shown in fig. 2 and 3, the inner surface 11a of the first deformation section 11 is in transition with the inner surface of the body section 1 through a round corner; the outer surface 11b of the first deformation section 11 is in rounded transition with the outer surface of the body section 1. Can improve the holistic continuity of sealing washer through the fillet transition to be difficult to appear using fatigue in the use, improve life, and the surface 11b of first deformation section 11 passes through the fillet transition with the surface of body section 1, has formed a breach, is favorable to outside atmospheric pressure to act on first deformation section 11.
In an embodiment, as shown in fig. 2 and 3, the end of the inner surface 11a of the first deforming section 11 that is close to the body section 1 is higher than the end of the outer surface 11b of the first deforming section 11 that is close to the body section 1. The design can increase the surface area of the inner surface 11a of the first deformation section 11, so that the contact area between the first deformation section 11 and the product 3 to be measured is larger, and the sealing performance is improved.
Specifically, the size and shape of the sealing ring can be adjusted according to the size and shape of a specific product to be tested, so that the sealing ring is convenient to mount and seal.
On the other hand, as shown in fig. 5, the utility model also provides a sealing leakage detection device, which comprises a sealing instrument (not shown), an upper die mounting block 2 and the sealing ring, wherein the upper die mounting block 2 is internally provided with a gas path channel 21, and the upper die mounting block 2 is provided with a mounting groove (not shown); the mounting groove encloses outside locating gas circuit 21's periphery, and the sealing washer is installed in the mounting groove and first deformation section 11 stretches out the mounting groove.
When the tightness of the product 3 to be detected is detected, the first deformation section 11 of the sealing ring is in contact with the product 3 to be detected, one end of the air channel 21 is communicated with a sealing instrument (not shown), so that negative pressure is formed among the sealing ring, the product 3 to be detected and the upper die mounting block 2, and after the first deformation section 11 of the sealing ring is tightly contacted with the product 3 to be detected, the tightness of the product 3 to be detected is detected by the sealing leakage detection equipment. Convenient operation, the sealed characteristics of revealing check out test set self production negative pressure of make full use of can not leave the impression or weigh wounded the product when reaching sealed state.
Taking the sealing ring in an embodiment as an example, when the sealing ring is installed on the installation groove, the first deformation section 11 extends out of the installation groove to contact with the surface of the product 3 to be tested. As shown in fig. 5, for the service condition of going up mould installation piece 2 when sealed detection is carried out to the product 3 that awaits measuring to sealed detection equipment that reveals, the arrow in the picture is the flow direction of air current, and when sealed detection equipment that reveals during operation, take out the air between sealing washer, the product 3 that awaits measuring and the last mould installation piece 2 through gas circuit passageway 21 and form the negative pressure, and under the effect of outside atmospheric pressure, first deformation section 11 produced the deformation this moment, with the product 3 in close contact with that awaits measuring, has reached sealed condition.
The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
