Description

Technical Field

[0001] The invention relates to the technical field of silicone strips, and in particular to a high-transparency silicone strip. Background Art

[0002] A silicone strip is a sealing strip with silicone rubber as the base material. It has a transparent appearance. Silicone strips are widely used in the fields of machinery, electronics, chemical industry, and medical treatment. Specific uses include mechanical sealing, electronic packaging, and medical materials. In the prior art, when silicone strips are used as sealing strips, the surface of the general silicone strips is relatively smooth, and the silicone strips need to be inserted into the groove where the silicone sealing strip is installed on the equipment. Since the surface of the silicone strips is smooth, the friction between the silicone strips and the side walls of the groove is small, causing the silicone strips to slip out of the installed grooves. The silicone strips need to be positioned again, affecting the installation efficiency of the silicone strips. To this end, the present invention improves the friction between the surface of the silicone strips and the groove where the silicone strips are installed on the equipment. Summary of the invention

[0003] The disclosed embodiment relates to a high-transparency silicone strip, wherein a transverse friction layer is distributed in a horizontal position on the outside of a soft silicone outer layer, and an annular friction layer is distributed in a vertical direction on the outside of the soft silicone outer layer, the transverse friction layer and the annular friction layer are staggered and connected, and when the soft silicone outer layer is inserted into a groove for installing a sealing strip of mechanical equipment, the transverse friction layer and the annular friction layer increase the friction between the outside of the soft silicone outer layer and the side wall of the installation groove, thereby preventing the silicone strip from slipping out when inserted into the groove, so that the silicone strip is stably placed in the installation groove, and there is no problem of falling off when the seal is used, thereby ensuring the sealing effect of the mechanical equipment.

[0004] In a first aspect of the present disclosure, a high-transparency silicone strip is provided, which specifically includes: a soft silicone outer layer, the top of the soft silicone outer layer is an arc-shaped structure, and the soft silicone outer layer is made of soft silicone material, and a tough layer is provided on the inner side of the soft silicone outer layer; the tough layer is made of wear-resistant material, and a nylon rope is provided inside the tough layer; the nylon rope is woven from nylon filaments, and a breakable traction piece is equidistantly distributed on the nylon rope; a thinner nylon filament is provided inside the breakable traction piece, and the breakable traction piece is made of silicone material.

[0005] In at least some embodiments, a positioning raised surface is provided on the outer top of the soft silicone outer layer; the positioning raised surface is an arc-shaped structure, and the positioning raised surface is made of transparent silicone material, and a fracture crack is opened on the positioning raised surface.

[0006] In at least some embodiments, the fracture crack and the breakable traction member are on the same vertical line, and a positioning toggle strip is provided at the top outer edge of the fracture crack, wherein the positioning toggle strip is made of a harder silicone material.

[0007] In at least some embodiments, a lateral friction layer is distributed on the outer side of the soft silicone outer layer, and an annular friction layer is also distributed on the outer side of the soft silicone outer layer; the annular friction layer and the lateral friction layer are staggered and connected together, and the top side end of the annular friction layer is connected to the positioning raised surface.

[0008] In at least some embodiments, a reinforcing wear-resistant layer is provided on the inner side of the toughness layer; and a filling layer is provided on the inner side of the reinforcing wear-resistant layer.

[0009] In at least some embodiments, the filling layer is made of silicone foam material, and weight-reducing inner holes are evenly distributed inside the filling layer.

[0010] In at least some embodiments, the weight-reducing inner hole is an elliptical structure, and a separation layer is provided inside the weight-reducing inner hole.

[0012] The present invention provides a high-transparency silicone strip, which has the following beneficial effects:

[0013] When the present invention is in use, the friction force in contact with the side wall of the equipment groove is increased by the transverse friction layer and the annular friction layer distributed on the outside of the soft silicone outer layer. When the silicone strip is used as a sealing strip on mechanical equipment, a transverse friction layer is distributed in a horizontal position on the outside of the soft silicone outer layer, and an annular friction layer is distributed in a vertical direction on the outside of the soft silicone outer layer. The transverse friction layer and the annular friction layer are connected in an alternating manner. When the soft silicone outer layer is inserted into the groove of the mechanical equipment sealing strip installation, the transverse friction layer and the annular friction layer increase the friction force between the outside of the soft silicone outer layer and the side wall of the installation groove, preventing the silicone strip from slipping out when inserted into the groove, so that the silicone strip is stably in the installation groove, and there is no problem of falling off when the seal is used, thereby ensuring the sealing effect of the mechanical equipment.

[0014] In addition, the weight of the silicone strip is reduced by using the weight-reducing inner holes in the filling layer. When the silicone strip is used as a sealing strip on mechanical equipment, a plurality of evenly arranged weight-reducing inner holes are provided inside the filling layer. On the one hand, the setting of the weight-reducing inner holes can reduce the overall weight of the silicone strip. On the other hand, a separation layer is provided in the weight-reducing inner holes to keep the weight-reducing inner holes in a sealed state. No debris will remain inside the weight-reducing inner holes to affect the flexibility characteristics of the silicone strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Please refer to Figures 1 to 8 :

[0031] Embodiment 1:

[0032] The present invention proposes a high-transparency silicone strip, comprising: a soft silicone outer layer 1, the top of the soft silicone outer layer 1 is an arc-shaped structure, and the soft silicone outer layer 1 is made of soft silicone material; a positioning protrusion 101 is provided on the outer top of the soft silicone outer layer 1; the positioning protrusion 101 is an arc-shaped structure, and the positioning protrusion 101 is made of transparent silicone material, and a fracture 102 is opened on the positioning protrusion 101; the fracture 102 and the breakable traction member 202 are on the same vertical line, and a positioning toggle strip 103 is provided at the top outer edge of the fracture 102, wherein the positioning toggle strip 103 is made of a harder silicone material; a transverse friction layer 104 is distributed on the outer side of the soft silicone outer layer 1, and an annular friction layer 105 is also distributed on the outer side of the soft silicone outer layer 1; the annular friction layer 105 and the transverse friction layer 104 are staggered and connected together, and the top side end of the annular friction layer 105 is connected together with the positioning protrusion 101.

[0033] In the disclosed embodiment, when the silicone strip is used as a sealing strip on mechanical equipment, the soft silicone outer layer 1 is made of soft silicone material. Adding a plasticizer during the production process can reduce the hardness of the silicone, making the soft silicone outer layer 1 soft and increasing the sealing effect. A lateral friction layer 104 and annular friction layer 105 are distributed on the outside of the soft silicone outer layer 1. The lateral friction layer 104 is in the horizontal direction of the soft silicone outer layer 1, and the annular friction layer 105 surrounds the outside of the soft silicone outer layer 1 in the vertical direction. The lateral friction layer 104 and the annular friction layer 105 are staggered and connected together to increase the soft silicone outer layer. The friction force on the surface of layer 1, when the soft silicone outer layer 1 is used as a sealing strip and inserted into the groove where the sealing strip of the mechanical equipment is installed, the lateral friction layer 104 and the annular friction layer 105 increase the friction force in contact with the side wall of the groove to prevent the silicone strip from slipping out and ensure the stability of the position of the silicone strip. When the soft silicone outer layer 1 needs to be cut off during use, the positioning toggle strips 103 on the two broken cracks 102 are moved by hand to increase the area of ​​the broken cracks 102 on the positioning raised surface 101, thereby breaking the soft silicone outer layer 1. It can be used without shearing tools, which is more convenient to use.

[0034] Embodiment 2, on the basis of embodiment 1, a tough layer 2 is provided on the inner side of the soft silicone outer layer 1; the tough layer 2 is made of wear-resistant material, and a nylon rope 201 is provided inside the tough layer 2; the nylon rope 201 is woven from nylon filaments, and the nylon rope 201 is evenly distributed with breakable traction members 202; the breakable traction member 202 is provided with thinner nylon filaments inside, and the breakable traction member 202 is made of silicone material; a reinforced wear-resistant layer 203 is provided on the inner side of the tough layer 2; a filling layer 204 is provided on the inner side of the reinforced wear-resistant layer 203; the filling layer 204 is made of silicone foam material, and the filling layer 204 is made of silicone foam material. The filling layer 204 has weight-reducing inner holes 205 evenly distributed inside; the weight-reducing inner holes 205 are of an elliptical structure, and a separation layer 206 is provided inside the weight-reducing inner holes 205; a hard silicone support layer 207 is provided on the inner side of the filling layer 204; the top of the hard silicone support layer 207 is of an arc structure, and the hard silicone support layer 207 is made of hard silicone. When the silicone strip is used as a sealing strip on mechanical equipment, a toughness layer 2 is provided on the inner side of the soft silicone outer layer 1, and a nylon rope 201 is provided inside the toughness layer 2, thereby increasing the toughness of the silicone strip and preventing the silicone strip from being broken at will. The breakable traction member 202 is in the same straight line as the fracture 102, so when the soft silicone outer layer 1 breaks, it breaks from the breakable traction member 202. A reinforcing wear-resistant layer 203 is provided on the inner side of the toughness layer 2 to increase the wear resistance of the silicone strip and prevent the silicone strip from being worn through, thereby ensuring the sealing of the silicone strip when used as a sealing strip. A filling layer 204 is provided on the inner side of the reinforcing wear-resistant layer 203. A weight-reducing inner hole 205 is provided inside the filling layer 204. The filling layer 204 is made of silicone foam material, so that the filling layer 204 and the weight-reducing inner hole 205 further reduce the weight of the silicone strip. A separation layer 206 is provided on the inner side of the weight-reducing inner hole 205, so that the weight-reducing inner hole 205 is in a sealed state, which has a certain buffering effect and reduces the external debris from entering the weight-reducing inner hole 205. A hard silicone support layer 207 is provided on the inner side of the filling layer 204. The hard silicone support layer 207 is made of hard silicone material. During the production process, the hardness of the silicone strip can be increased by increasing the filler ratio, so that the hard silicone support layer 207 supports the silicone strip in a suitable state to prevent deformation caused by extrusion during transportation, resulting in uneven distribution of the silicone strip and affecting its sealing effect.

[0035] The working principle of this embodiment: when in use, the transverse friction layer 104 is in the horizontal direction of the soft silicone outer layer 1, and the annular friction layer 105 surrounds the outside of the soft silicone outer layer 1 in the vertical direction. The transverse friction layer 104 and the annular friction layer 105 are staggered and connected together to increase the friction force on the surface of the soft silicone outer layer 1. When the soft silicone outer layer 1 is inserted into the groove where the sealing strip of the mechanical equipment is installed as a sealing strip, the transverse friction layer 104 and the annular friction layer 105 increase the friction force in contact with the side wall of the groove. When the soft silicone outer layer 1 needs to be cut off, the positioning toggle strips 103 on the two broken cracks 102 are moved by hand to increase the area of ​​the broken cracks 102 on the positioning convex surface 101 to disconnect the soft silicone outer layer 1, and the soft silicone outer layer 1 is cut off. A toughness layer 2 is provided on the inner side of layer 1, and a nylon rope 201 is provided inside the toughness layer 2 to increase the toughness of the silicone strip. A reinforcement wear-resistant layer 203 is provided on the inner side of the toughness layer 2 to increase the wear resistance of the silicone strip. A filling layer 204 is provided on the inner side of the reinforcement wear-resistant layer 203, and a weight-reducing inner hole 205 is provided inside the filling layer 204. The filling layer 204 and the weight-reducing inner hole 205 further reduce the weight of the silicone strip. A hard silicone support layer 207 is provided on the inner side of the filling layer 204. The hard silicone support layer 207 is made of hard silicone material. The hardness of the silicone strip can be increased by increasing the proportion of fillers during the production process. The hard silicone support layer 207 supports the silicone strip in a suitable state to prevent deformation caused by extrusion during transportation.
