Abstract
Description
Technical Field
[0001] This invention relates to the field of equipment storage and protection technology, specifically, to a sealing structure for equipment protective covers. Background Technology
[0002] Using enclosure storage technology to store equipment and supplies is an effective protective measure to mitigate the environmental effects on these materials. Enclosure storage technology includes enclosure materials, enclosure sealing, and internal environment control, with enclosure sealing technology being the key technology. Currently, there are two main enclosure sealing methods used domestically and internationally. One method is heat welding to seal the upper and lower enclosure bodies. This method provides a reliable seal, but requires re-welding after each opening, making it inconvenient to use and maintain. The other method uses strip-shaped sealing zippers to seal the upper and lower enclosure bodies. Its basic principle is that two sealing strips with serrated edges and grooves are pre-welded to the upper and lower enclosure bodies respectively. Under external pressure, the sealing strips interlock, sealing the enclosure. This method, which allows for repeated opening and closing and is easy to use, is widely adopted. However, existing strip-type sealing zippers still have some technical problems in application: When used in high-temperature environments, the upper and lower sealing strips of the strip-type sealing zipper soften and harden after heating, reducing the force of the shoulder on the groove. This makes it easy for the outer edge of the outer protrusion of the upper sealing strip and the two protrusions to detach sequentially from the groove of the lower sealing strip when the strip-type sealing zipper is pulled by external forces such as the weight of the lower sleeve itself. This results in gaps between the upper and lower sealing strips, compromising the sealing performance of the strip seal, and in severe cases, even causing the upper and lower sealing strips to automatically separate and fall off. The existence of these problems seriously restricts the application of the sleeve sealing technology in the field of equipment and material sealing technology. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a sealing structure for a protective cover of equipment, which achieves sealing and anti-detachment functions by relying on the mutual compression and elastic contact between the protrusions and grooves, between the shoulders, between the tenons and the side walls of the edge cavity, and between the tenons and the edge of the tenons on the sealing mechanism.
[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a strip-shaped sealing zipper composed of an upper sealing strip and a lower sealing strip of the same structure that mesh in opposite directions. The upper sealing strip includes a welded connecting edge and an engaging sealing mechanism. One end of the welded connecting edge is connected to the engaging sealing mechanism. The engaging sealing mechanism includes multiple spaced and parallel grooves. A protruding tooth is provided between two adjacent grooves to engage with the groove. A tenon is provided at the end of the engaging sealing mechanism near the welded connecting edge. An edge-sealing cavity is provided at the end of the engaging sealing mechanism away from the welded connecting edge to engage with the tenon. The parts where the tenon intersects with the groove, the parts where the groove intersects with the protruding tooth, and the parts where the protruding tooth intersects with the edge-sealing cavity all form a barbed shoulder.
[0005] The beneficial effects are:
[0006] By relying on the mutual compression and elastic contact between the protrusions and grooves, between the shoulders, between the tenons and the side walls of the edging cavity, and between the tenons and the edging on the sealing mechanism, the strip-shaped sealing zipper not only ensures high sealing performance, but also effectively prevents the upper and lower sealing strips from separating, thus improving the engagement stability and reliability of the strip-shaped sealing zipper.
[0007] Based on the above technical solution, the present invention can be further improved as follows.
[0008] Furthermore, the groove is a T-shaped groove, and the protrusion is an inverted T-shaped protrusion.
[0009] The advantages of adopting the above-mentioned further solutions are a stable connection and good sealing performance.
[0010] Furthermore, the cross-sectional width of the hook-shaped shoulder is not greater than 1 / 2 of the radius of the protruding tooth.
[0011] The advantage of adopting the above-mentioned further solution is that it can effectively prevent the upper and lower sealing strips from separating.
[0012] Furthermore, the outer side of the edging cavity is provided with a tenon-shaped edging.
[0013] The beneficial effect of adopting the above-mentioned further solution is that the tenons and the tenon edges come into contact with each other and undergo partial compression deformation.
[0014] Furthermore, it also includes the outer wall of the groove of the engagement sealing mechanism, which is composed of multiple arcs with the same radius that are concentric with the outer wall arc curves of the multiple grooves and the edge cavity, and intersecting continuously.
[0015] The advantage of adopting the above-mentioned further solution is that it facilitates the use of sealing tools to compress the sealing strip.
[0016] Furthermore, the outer wall arc curves of both the groove and the protrusion are larger than the arc curve of the semicircle, and the radius of the protrusion is larger than the radius of the groove.
[0017] The advantage of adopting the above-mentioned further solution is that it facilitates the entry of the protruding teeth into the groove, where they press against each other and maintain elastic contact, thereby sealing the upper and lower sealing strips.
[0018] Furthermore, the cross-sectional radii of the tenon and the protruding tooth are equal, the cross-sectional radius of the tenon is greater than the cross-sectional radius of the groove, and the cross-sectional radius of the protruding tooth is greater than the cross-sectional radius of the edge-sealing cavity.
[0019] The advantage of adopting the above-mentioned further solution is that it facilitates the mutual compression and elastic contact between the groove and the tooth, the tenon and the edge cavity.
[0020] Furthermore, the number of grooves and protrusions is at least three.
[0021] The beneficial effect of adopting the above-mentioned further solution is that multiple protruding teeth are locked in the corresponding grooves, thereby improving the sealing performance. Attached Figure Description

[0026] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0027] Example 1:
[0028] like Figure 1As shown, in this embodiment, a lower sealing strip 10 equipped with a protective cover sealing structure includes a tenon 1, a welded connection edge 2, three grooves 3, an outer wall of the groove of the meshing sealing mechanism 4, a shoulder 5, three protruding teeth 6, an edge-wrapping cavity 7, and a tenon edge wrapping 8. The cross-sectional shape of the welded connection edge 2 is trapezoidal, with a length of 120mm-200mm and a thickness that gradually decreases from 1.2mm-1.5mm to 1.0mm-1.2mm, and is used to connect with the cover material by high-frequency welding or ultrasonic welding. Both the groove 3 and the protruding tooth 6 have a semi-circular cross-sectional shape with a radius of 0.3mm-0.6mm, and the radius of the protruding tooth 6 is 0.01mm-0.02mm larger than that of the groove 3. The intersection of the groove 3 and the protruding tooth 6 forms a planar barbed shoulder 5 with a cross-sectional width of 0.75mm-0.15mm. The cross-sectional shapes of the tenon 1 and the edging cavity 7 are similar and corresponding. The curved part of the tenon 1 is an arc with the same radius as the cross-sectional radius of the protruding tooth 6, and the curved part of the edging cavity 7 is an arc with the same radius as the cross-sectional radius of the groove 3. The outer contour curve of the groove outer wall 4 of the meshing sealing mechanism is a continuous intersecting arc with a radius of 1.3mm-2.1mm. The wall thickness of the tenon edging 8 is 1mm-2mm. One end of the welded connection edge 2 is connected to the first groove 3 on the left. A protruding tooth 6 is provided between two adjacent grooves 3 to engage with the groove 3. A tenon 1 is provided at the end of the first groove 3 on the left near the welded connection edge 2. The last protruding tooth 6 on the right is connected to an edge-sealing cavity 7 to engage with the tenon 1. The parts where the tenon 1 intersects with the groove 3, the parts where the groove 3 intersects with the protruding tooth 6, and the parts where the protruding tooth 6 intersects with the edge-sealing cavity 7 all form a barbed shoulder 5.
[0029] Example 2:
[0030] like Figure 2As shown, the protective sleeve sealing structure of the present invention comprises a strip-shaped sealing zipper composed of an upper sealing strip 9 and a lower sealing strip 10 of the same structure that mesh in opposite directions. Under a certain pressure, the corresponding protrusions 6 of the upper sealing strip 9 and the lower sealing strip 10 come into contact with each other, between the protrusions 6 and the latch 1, and between the latch 1 and the latch edge 8, and undergo partial compression deformation, causing the protrusions 6 to enter the groove 3 and the latch 1 to enter the edge cavity 7. Subsequently, the protrusions 6, the latch 1, and the latch edge 8 undergo partial elastic recovery. During the elastic recovery process, the grooves 6, 1, and 8 undergo partial elastic recovery. The groove 3 and the protruding tooth 6, the shoulder 5 and the shoulder 5, the tenon 1 and the side wall of the edge cavity 7, and the tenon 1 and the tenon edge 8 all press against each other and maintain elastic contact, thereby sealing the gap between the lower sealing strip 10 and the upper sealing strip 9 and achieving the sealing of the strip sealing zipper; the shoulders 5 of the upper and lower sealing strips press against each other and elastically clamp, locking the protruding tooth 6 in the groove 3, the tenon 1 elastically clamps the corresponding shoulder 5, and the tenon edge 8 uses its own rigidity and elastic deformation to surround and lock the tenon 1 in the edge cavity 7, preventing the upper and lower sealing strips from separating.
[0031] Preferably, the groove 3 is a T-shaped groove, and the protrusion 6 is an inverted T-shaped protrusion.
[0032] When using this device, the upper sealing strip 9 and the lower sealing strip 10 are sealed by manual squeezing or by using an adapter.
