Description

Technical Field

[0001] The invention relates to the technical field of insulating tapes, and in particular to a tool for using and storing electrical insulating tapes. Background Art

[0002] Insulating tapes are often used in the operation of power systems. These insulating tapes are all in standard sizes and are usually torn by hand or cut into sections with scissors. They are often left anywhere during use and before and after use, or even thrown directly on the ground, which is very inconvenient.

[0003] Existing insulating tapes need to be cut with scissors, knives or other sharp tools when in use. In many cases, it is difficult to find a sharp tool that can cut the tape, so it is a bit troublesome to use. After use, it is necessary to carry knives and other items to cut the tape, which brings great trouble to the user. In addition, the cutting blade needs to be hidden manually. If it is not hidden and placed in the package, the user may be cut by the cutting blade when reaching into the package to take the tool blindly. Summary of the invention

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments 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.

[0036] Embodiment 1:

[0037] A tool for using and storing electrical insulating tape, such as Figure 1-6 As shown:

[0038] It includes a shell 100, a shearing structure, an insulating tape 300 and a magnetic buckle 401.

[0039] The housing 100 is a rectangular structure with a hollow interior. The top wall of the housing 100 is provided with a first notch 101 and a second notch 102. The inner cavity of the housing 100 forms a first cavity 103 and a second cavity 104. The front side wall of the housing 100 is designed to be open.

[0040] The shearing structure includes a button 201, a connecting rod 202, a rotating shaft 203, a spring 204 and a slice 205. The connecting rod 202, the rotating shaft 203, the spring 204 and the slice 205 are accommodated in the first cavity 103 and the second cavity 104. The button 201 is placed outside the housing 100 and connected to one end of the connecting rod 202, and can slide up and down under force. The slice 205 is fixed to the other end of the connecting rod 202. There is a fixed shaft 206 at the lower part of the housing 100 and the mirror position of the rotating shaft 203; the first notch 101 matches the size of the insulating tape 300, and the insulating tape 300 can be inserted from here;

[0041] The two ends of the spring 204 are respectively connected to the connecting rod 202 and the inner wall of the housing 100;

[0042] The second notch 102 is the entrance and exit of the slice 205. The card cover 105 is a sealing surface of the front side wall of the shell 100 and matches with the card slot 108 of the front side wall of the shell 100, and can be pushed and pulled up and down.

[0043] The outer walls of the rotating shaft 203 and the fixed shaft 206 are both sleeved with corresponding insulating tapes 300. After the card cover 105 is pulled out and the insulating tapes 300 are taken out, the magnetic sheet 106 can be seen.

[0044] The magnetic buckle 401 is a T-shaped structure consisting of a cylinder and a disc. The outer diameter of the cylinder is smaller than the outer diameter of the disc. The outer diameter of the end of the magnetic buckle 401 with a smaller outer diameter is adapted to the inner diameter of the center hole 303 of the insulating tape 300. The inner diameter of the inner ring of the magnetic buckle 401 matches the outer diameters of the rotating shaft 203 and the fixed shaft 206.

[0045] The magnetic sheet 106 is a circular sheet structure, and the inner diameter of the magnetic sheet 106 matches the outer diameter of the rotating shaft 203 and the fixed shaft 206; or the inner diameter of the magnetic sheet 106 matches the outer diameter of the circular sheet of the magnetic buckle 401, and can be smoothly inserted therein to realize the magnetic sheet 106 and the magnetic buckle 401 being connected as one.

[0046] The card cover 105 can be detached from the card slot 108 on the front side wall of the shell 100. The card cover 105 has a corresponding magnetic sheet 106 built in. The magnetic sheet 106 built into the card cover 105 cooperates with the magnetic sheet 106 on the magnetic buckle 401 by magnetic attraction, which helps to prevent the card cover 105 from detaching.

[0047] Insert the two cylindrical magnetic buckles 401 from the left and right sides of the central hole 303 of the insulating tape 300 respectively, and then put them on the outer walls of the rotating shaft 203 and the fixed shaft 206. The two magnetic sheets 106 cooperate with each other to further press the two sets of magnetic buckles 401 on the opposite sides of the insulating tape 300.

[0048] The specific usage is as follows:

[0049] Storage method: Figure 4 , 5 As shown, the two cylinders of the magnetic buckles 401 are respectively inserted from the left and right sides of the central hole 303 of the insulating tape 300, and are attracted to each other through the magnetic attraction of the two sets of magnetic sheets 106 on the outside, and then placed on the rotating shaft 203 and the fixed shaft 206, and finally the card cover 105 is pushed on.

[0050] Tape cutting method: Figure 6 As shown, the free end of the insulating tape 300 is inserted into the first notch 101 and pulled out to a certain length. The left hand holds the tool and the thumb turns the button 201 downward. The button 201 drives the end of the connecting rod 202 to move downward around the rotating shaft 203, and at the same time drives the slice 205 to pass through the second notch 102. The spring 204 is stretched and stores energy. The right hand pulls the insulating tape 300 hard and cuts it through the slice 205. If it is necessary to continue cutting, the right hand pulls the insulating tape 300 hard again and cuts it through the slice 205, and repeats this process. When it stops using, release the left thumb. Under the pulling force of the spring 204, the button 201, the connecting rod 202 and the slice 205 are reset and hidden in the first cavity 103 and the second cavity 104. The remaining exposed part of the insulating tape 300 can be pasted on the side of the housing 100 for easy use next time. When not used for a long time, the device can be taken out from the first notch 101 and wrapped around the insulating tape 300 to restore the original state.

[0051] Usage of magnetism: When the work document (paper) needs to be adsorbed on the cabinet door or other housing for convenient work, the magnetism sheet 106 in the housing can be temporarily taken out to adsorb the work document (paper) on the cabinet door or other housing. The magnetism buckle 401 with the magnetism sheet 106 and the insulating tape 300 can also be used to adsorb the work document (paper) on the cabinet door or other housing. Take out the card cover 105, and the work document (paper) can also be adsorbed on the cabinet door or other housing through the card cover 105. In addition, the entire tool can also be adsorbed on the cabinet door or other housing through the card cover for convenient use.

[0052] Embodiment 2: Contains all the contents of Embodiment 1, such as Figure 7 As shown:

[0053] The housing 100 has a built-in time-delay structure, which includes a cylinder 501, a piston block 502, a hinge rod 503, a one-way air outlet valve 504, a one-way air inlet valve 505, a blocking member 506 and a return spring 507;

[0054] The cylinder 501 is fixed to the inner wall of the shell 100, and the piston block 502 slides in the inner cavity of the cylinder 501 in an airtight manner. A one-way air inlet valve 505 is installed at the air inlet of the cylinder 501, and a one-way air outlet valve 504 is installed at the air outlet of the cylinder 501. The two ends of the hinged rod 503 are hinged to the piston block 502 and the connecting rod 202 respectively, and the ventilation flow of the one-way air inlet valve 505 is much greater than the ventilation flow of the one-way air outlet valve 504.

[0055] When the slice 205 passes through the second notch 102, the external gas enters the inner cavity of the cylinder 501 through the one-way air inlet valve 505. At this time, the left thumb can release the button 201, and the gas in the inner cavity of the cylinder 501 is slowly discharged from the one-way air outlet valve 504 under the pulling force of the spring 204, so that the slice 205 can still stay outside for a period of time when it loses external support.

[0056] Embodiment 3: Contains all the contents of Embodiment 2, such as Figure 8 As shown:

[0057] The inner cavity of the cylinder 501 is linearly slidably connected with a blocking piece 506, a return spring 507 is connected between the blocking piece 506 and the inner wall of the cylinder 501, one end of the blocking piece 506 is matched with the air outlet of the cylinder 501, and the inner wall of the air outlet is provided with a sealing layer, and a one-way friction pattern is provided on the sealing layer;

[0058] Under normal circumstances, the air inlet is closed under the elastic force of the return spring 507, and the external air source pushes open the blocking piece 506 when entering from the air inlet, so that the end of the blocking piece 506 is inserted into the air outlet. During this process, the friction force of the one-way friction pattern is small and will not hinder the insertion of the blocking piece 506.

[0059] Afterwards, the elastic force of the return spring 507 pushes the end of the blocking member 506 to be withdrawn. During this process, the friction between the one-way friction pattern on the sealing layer and the end of the blocking member 506 is relatively large, so that the speed of withdrawing the end of the blocking member 506 is relatively slow.

[0060] The above design ensures that, before the end of the blocking member 506 is withdrawn from the air outlet, a sealed space is formed in the inner cavity of the cylinder 501 , thereby preventing the slice 205 from being quickly retracted into the inner cavity of the housing 100 due to excessive external force applied to the slice 205 .

[0061] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
