Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Examples
As shown in fig. 1 to 5, this embodiment the oil-resistant rubber sealing strip includes the sealing strip body 10, the surface array of sealing strip body 10 has adsorption component 20, adsorption component 20 includes that the surface is to keeping away from the sunken bowl shape piece 21 in sealing strip body 10 one side, and bowl shape piece 21 can be to the shrink of sealing strip body 10 one side.
In the prior art, the sealing strip is usually in a strip shape or an arc shape, a groove or a rib is formed in the surface of the sealing strip, and the groove or the rib has a clamping effect to isolate the flow of air, so that a sealing effect is achieved. However, such a snap connection is relatively weak, and when the external pressing force is small or the force is unbalanced, the sealing tape automatically falls off, and the sealing effect is lost.
During the use, in this technical scheme, set up bowl shape piece 21 through extra surface at sealing strip body 10, when bowl shape piece 21 contacts with sealed face, receive the inside air of extruded discharge bowl shape piece 21, contact and adsorb with sealed face, thereby play the fixed action to sealing strip body 10, avoid sealing strip body 10 to produce easily and drop, moreover, because bowl shape piece 21 can locate to stretch out and draw back to sealing strip body 10, at the fixed back of sealing strip body 10, bowl shape piece 21 can expand gradually, play the filling effect between sealing strip body 10 and sealed face, increase sealed effect.
Referring to fig. 2, the concave surface of the bowl-shaped piece 21 on the side away from the sealing strip body 10 is bowl-shaped, and the diameter of the bowl-shaped piece is approximately between 2.5 times and 3.5 times of the maximum depth of the bowl-shaped piece 21; specifically, the bowl-shaped piece 21 is made of a material having elasticity, such as natural rubber or synthetic rubber, preferably fluororubber having good properties; when utilizing sealing strip body 10 to seal, bowl shape piece 21 can adsorb on sealed face, can prevent that sealing strip body 10 from breaking away from, increases the sealed effect of sealing strip body 10.
Referring to fig. 2 and 4, further, a buffer sheet 25 made of an elastic material is fixedly connected to the bottom end of the bowl-shaped sheet 21, and the buffer sheet 25 is fixedly connected to the weather strip body 10. Since the weather strip body 10 is made of an elastic material, such as rubber or a foam material, and has a good elasticity, when the bowl-shaped piece 21 is subjected to a large pressure, the weather strip can provide a buffering capacity, and the bowl-shaped piece 21 is prevented from being unable to recover due to excessive deformation.
Referring to fig. 2 and fig. 3, as an alternative to the buffer sheet 25, a buffer column 22 is disposed at the bottom end of the bowl-shaped sheet 21, a buffer groove 24 is disposed on the surface of the weatherstrip body 10 opposite to the buffer column 22, the buffer column 22 is adapted to the buffer groove 24, and the buffer groove 24 is filled with compressed gas; that is, the tip that utilizes buffer column 22 extends to the inside of dashpot 24 for buffer column 22 can slide along dashpot 24 is inside, borrows this to realize bowl shape piece 21 along the flexible effect in sealing strip body 10 surface, after bowl shape piece 21 surface atress, extrudees buffer column 22 and stretches into to the inside of dashpot 24, cooperates gaseous further compressed, constitutes buffering effect, and expanding compressed gas can promote popping out of buffer column 22.
Referring to fig. 3, a friction ring 23 is sleeved on the outer wall of the buffer column 22, and the outer edge of the friction ring 23 is tightly attached to the inner wall of the buffer slot 24 to form damping; because of the damping, the damping column 22 has a large resistance to sliding along the inside of the damping groove 24, and the bowl-shaped piece 21 can be damped by the resistance.
Referring to fig. 3, the outer diameter of the friction ring 23 is larger than the outer diameter of the buffer groove 24 at the opening of the surface of the weather strip body 10; therefore, the bowl-shaped piece 21 is not separated from the inside of the buffer groove 24 after being subjected to a large pressure.
Referring to fig. 3 and 5, an inner air absorption groove 211 is further formed in the inner side surface of the bowl-shaped sheet 21, and the distribution of the inner air absorption groove 211 on the surface of the bowl-shaped sheet 21 is gradually sparse from the outside to the center; the inner air absorption grooves 211 are formed on the surface of the bowl-shaped piece 21 to enhance the absorption capacity of the bowl-shaped piece 21.
Referring to fig. 3 and 5, an outer air suction groove 212 is formed on the surface of the bowl-shaped piece 21 close to the sealing strip body 10, and the distribution density of the outer air suction groove 212 is approximately half of that of the inner air suction groove 211; the bowl-shaped piece 21 can be fixed by utilizing the outer suction groove 212 to be adsorbed on the surface of the sealing strip body 10, thereby saving the space occupation.
Referring to fig. 2, further, a reinforcing outer ring can be added to the extension of the bowl-shaped piece 21, and the material of the outer ring is consistent with that of the weather strip body 10, so that the bowl-shaped piece 21 can be prevented from being deformed.
