Description

Technical Field

[0001] The utility model relates to the technical field of conductive and thermally conductive adhesive tapes, in particular to a conductive and thermally conductive adhesive tape which is convenient to store. Background Art

[0002] Conductive tape is a metal foil or conductive cloth with a highly conductive backing adhesive. Its conductive backing adhesive and conductive substrate form a complete conductor, which can be bonded to any metal surface to complete electrical overlap and electrical sealing of gaps. Shielded conductive tape is an economical and easy-to-use shielding material used to seal EMI shielding rooms, seams of housings and electronic equipment, wrap cables for shielding, provide a reliable grounding surface, and provide electrical contact for surfaces that cannot be welded.

[0003] An existing patent (authorization announcement number: CN 215974405 U) discloses a conductive and thermally conductive tape that is easy to store. An inner tape roller is installed through a rotating shaft. The inner tape roller is provided with an inner tape layer with a different conductive and thermal conductivity coefficient from the outer tape layer. When in use, the inner tape roller can be directly pulled out from the inside of the outer tape roller to use the inner tape layer on the inner tape roller, and then the inner tape roller is pushed inward to reset, which is more convenient to use and store.

[0004] However, the above technical solutions still have certain defects. The tapes are all exposed to the outside. During use or carrying, dust or moisture can easily enter the tape rolled into a disc, causing the tape to lose its original adhesiveness. At the same time, before use, it is necessary to slide the fingertips on the outermost layer of the tape roll to find the tape head before tearing the tape off. Since the tape body is relatively thin, people often have to slide back and forth on the tape layer for several circles to find the tape head. Therefore, a conductive and thermally conductive tape that is easy to store is proposed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a conductive and thermally conductive tape that is easy to store, so as to solve the technical problems raised in the above background.

[0007] The shearing assembly includes two groups of positioning arms fixed to the inner wall of the lower shell, a positioning shaft is rotatably provided between the two groups of positioning arms, a bottom strip fixed to the two groups of positioning arms is provided above the positioning shaft, a pressing strip slidably provided with the positioning arms is provided above the bottom strip, a shearing knife extending into the bottom strip is fixed to the bottom end of the pressing strip, and a penetrating knife groove is provided on the upper surface of the bottom strip at the contact position with the shearing knife.

[0008] As a preferred technical solution for the convenient storage of the conductive and thermally conductive tape of the utility model, the lower surface of the upper shell and the upper surface of the lower shell are both inlaid with a pair of magnet strips, and the magnets inlaid in the upper shell and the lower shell are of opposite sex.

[0009] As a preferred technical solution for the convenient storage of the conductive and thermally conductive tape of the utility model, a notch is provided in the lower shell at the position in contact with the positioning arm, and a notch is provided at the position corresponding to the positioning arm of the upper shell.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0024] The following describes an embodiment of the utility model based on its overall structure.

[0025] A conveniently stored electrically conductive thermal tape, such as Figures 1 to 6 As shown, it comprises a lower shell 100, an upper shell 110 is rotatably provided on the upper surface of the lower shell 100, a constraint shaft 101 is fixed at the center position of the circle in the lower shell 100, an adhesive tape ring 140 is movably sleeved on the outer wall of the constraint shaft 101, an adhesive tape 130 is wound around the outer wall of the adhesive tape ring 140, and a shearing assembly 120 fixed to the inner wall of the lower shell 100 is provided at the free end of the adhesive tape 130;

[0026] The shearing assembly 120 includes two groups of positioning arms 121 fixed to the inner wall of the lower housing 100, a positioning shaft 122 is rotatably provided between the two groups of positioning arms 121, a bottom bar 123 fixed to the two groups of positioning arms 121 is provided above the positioning shaft 122, a pressing bar 124 slidably provided with the positioning arms 121 is provided above the bottom bar 123, a shearing knife 128 extending into the bottom bar 123 is fixed to the bottom end of the pressing bar 124, and a through knife groove 127 is provided at the contact position between the upper surface of the bottom bar 123 and the shearing knife 128;

[0027] Slide blocks 125 extending into the positioning arm 121 are provided at both ends of the pressing strip 124 . A sliding groove is provided at the contact position between the positioning arm 121 and the sliding block 125 . A spring 126 is fixed to the inner wall of the bottom end of the sliding groove and the bottom end of the sliding block 125 .

[0028] When in use, the upper shell 110 is pushed upward to rotate it around the rotation point with the lower shell 100 to open, so that the adhesive tape 130 is exposed outside, and at the same time, the positioning shaft 122 is turned to the right by the finger to make the free end of the adhesive tape 130 extend a certain amount, which is convenient for manual tearing of the adhesive tape head from the outer wall of the positioning shaft 122 and applying a horizontal external force to pull out the adhesive tape 130 for use. When the adhesive tape 130 needs to be cut, a vertical downward external force is applied to the pressing strip 124, and at the same time, the slider 125 slides in the slide groove and compresses the spring 126, so that the bottom end of the shearing knife 128 extends out of the bottom end of the knife groove 127 and contacts with the adhesive tape 130 to complete the cutting, thereby achieving the purpose of convenient use of the adhesive tape and avoiding the situation where the adhesive tape head is difficult to store due to external force breaking;

[0029] The external force applied to the pressing strip 124 is removed and the pressing strip 124 is reset to the left and right of the spring 126, so that the tape 130 can be cut next time. At the same time, the free end of the cut tape 130 is attached to the outer wall of the positioning shaft 122. The tape head can be easily found by continuing to rotate the positioning shaft 122 when it is used next time.

[0030] As the upper shell 110 is rotated and brought into contact with the upper shell 110 , the used adhesive tape 130 is sealed and stored, which can provide waterproof and dustproof protection for the adhesive tape 130 and ensure the adhesiveness of the adhesive tape 130 itself.

[0031] Please refer to Figure 2 A pair of magnet strips 111 are embedded in the lower surface of the upper shell 110 and the upper surface of the lower shell 100. The magnets embedded in the upper shell 110 and the lower shell 100 are of opposite sex.

[0032] By utilizing the adsorption force between the magnet strips 111 , the upper housing 110 and the lower housing 100 are closed and stable, and will not be opened arbitrarily to cause dust intrusion.

[0033] Please refer to Figure 1 A notch is formed in the lower housing 100 at a position in contact with the positioning arm 121 , and a notch is formed in the upper housing 110 at a position corresponding to the positioning arm 121 .

[0034] A hidden space is provided for the positioning arm 121 , and the closing of the lower housing 100 and the upper housing 110 is not affected.

[0035] Please refer to Figure 1 The free end of the adhesive tape 130 passes through the gap between the positioning shaft 122 and the bottom strip 123 , and the free end of the adhesive tape 130 is adhered to the upper outer wall of the positioning shaft 122 .

[0036] The positioning shaft 122 and the bottom strip 123 constrain the tape, allowing it to extend straight along a preset installation track, while the free end can be attached to the outer wall of the positioning shaft 122, making it easy to quickly find the tape head next time it is used.

[0037] Please refer to Figure 5 Both ends of the positioning shaft 122 are provided with positioning plates extending into the positioning arm 121, and a blind hole is opened at the contact position between the positioning arm 121 and the positioning plate.

[0038] It is convenient to manually rotate the positioning shaft 122 so that the free end of the adhesive tape 130 extends to a certain size, thereby facilitating manual tearing of the adhesive tape 130 .

[0039] Please refer to Figure 3 A rubber ring is wrapped at the contact position between the outer wall of the constraint shaft 101 and the inner wall of the tape ring 140.

[0040] The rubber ring is used to increase the friction between the constraint shaft 101 and the tape ring 140 to prevent the tape ring 140 from rotating too flexibly and causing the tape 130 to extend too much in the lower housing 100 and cause waste.

[0041] When in use, the upper shell 110 is pushed upward to rotate it around the rotation point with the lower shell 100 to open, so that the adhesive tape 130 is exposed outside, and at the same time, the positioning shaft 122 is turned to the right by the finger to make the free end of the adhesive tape 130 extend a certain amount, which is convenient for manual tearing of the adhesive tape head from the outer wall of the positioning shaft 122 and applying a horizontal external force to pull out the adhesive tape 130 for use. When the adhesive tape 130 needs to be cut, a vertical downward external force is applied to the pressing strip 124, and at the same time, the slider 125 slides in the slide groove and compresses the spring 126, so that the bottom end of the shearing knife 128 extends out of the bottom end of the knife groove 127 and contacts with the adhesive tape 130 to complete the cutting, thereby achieving the purpose of convenient use of the adhesive tape and avoiding the situation where the adhesive tape head is difficult to store due to external force breaking;

[0042] The external force applied to the pressing strip 124 is removed and the pressing strip 124 is reset to the left and right of the spring 126, so that the tape 130 can be cut next time. At the same time, the free end of the cut tape 130 is attached to the outer wall of the positioning shaft 122. The tape head can be easily found by continuing to rotate the positioning shaft 122 when it is used next time.

[0043] As the upper shell 110 is rotated and contacted with the upper shell 110, the used tape 130 is sealed and stored, which can protect the tape 130 from water and dust and ensure the adhesiveness of the tape 130 itself. The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology.

[0044] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
