[0002] Conductive tape is a kind of tape product that makes a conductive medium into an adhesive. Conductive tape has the characteristics of good softness, strong adhesion, good conductivity, etc. It is widely used in the field of anti-shielding. It has better conductivity than metal and is easy to process. Conductive tape is a metal foil or conductive cloth with high conductive adhesive. Its conductive 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.

[0003] At present, when laying the conductive tape, the staff often directly pulls out a certain length from the conductive tape roll, and then adheres the conductive tape to the required shielding position, and directly cuts off the excess conductive tape. It is difficult to control the required length of the conductive tape, which may cause the conductive tape to be pulled out too long, and then a lot of waste conductive tape is cut, resulting in a large amount of resource waste. In the prior art, measuring tools such as rulers are often used to control the required length of the conductive tape. Since both hands of the staff are occupied when tearing the conductive tape, it may affect the staff's operation, thereby reducing the accuracy and standardization of the installation of the conductive tape;

[0004] Therefore, there is an urgent need to improve the length measuring device for the conductive tape to solve the above-mentioned problems. Utility Model Content

[0026] The measuring principle of the measuring wheelbarrow is adopted. The measuring circle 3 is driven to rotate by tearing the conductive tape 7. The permanent magnet 4 on the measuring circle 3 will induce the circuit board 5. The circuit board 5 transmits the data of the rotation of the measuring circle 3 to the counter 6 through the wire. The counter 6 can read the length of the conductive tape, and the length of the conductive tape can be effectively controlled, thereby reducing the waste of resources. There is no need to use measuring tools such as rulers, which is convenient for the operation of the staff, thereby improving the accuracy and standardization of the installation of the conductive tape.

[0027] Further, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a conductive tape rotating shaft 101 is fixedly installed at the bottom end of the shell 1, a damping ring 102 is fixedly arranged on the conductive tape rotating shaft 101, a damping ring 102 is provided on the damping ring 102, a damping block sliding guide hole 103 is provided on the damping ring 102, a damping block 104 is vertically slidably arranged inside the damping block sliding guide hole 103, a damping spring 105 is fixedly connected to the side of the damping block 104, one end of the damping spring 105 away from the damping block 104 is fixedly connected to the inside of the damping block sliding guide hole 103, a plurality of evenly distributed damping grooves 702 are provided on the conductive tape center ring 701, and the damping grooves 702 correspond to the damping spring 105, the damping ring 102 can increase the friction force of the conductive tape 7 when it rotates, reduce the inertia of the conductive tape 7 when it rotates, and prevent the staff from using too much force, resulting in the conductive tape 7 being pulled out to a length exceeding the required length, thereby improving the practicality of the conductive tape length measuring device.

[0028] Furthermore, if Figure 1 and Figure 5As shown, a conductive tape center ring 701 is arranged inside the conductive tape 7, and the conductive tape 7 is rotatably arranged on the conductive tape rotating shaft 101 through the conductive tape center ring 701; one end of the conductive tape rotating shaft 101 away from the damping ring 102 is rotatably connected with a conductive tape positioning ring 106 through a thread, and one side of the conductive tape positioning ring 106 is against the conductive tape center ring 701; the conductive tape positioning ring 106 is used to position the conductive tape center ring 701 to prevent the conductive tape 7 from tilting and getting stuck when rotating, thereby improving the stability of the conductive tape length measuring device, and also making it convenient to replace the conductive tape 7 when it is used up, which is convenient for the installation of the staff.

The handle 107 is convenient for the staff to hold and operate, and the rubber pad 108 fits the palm of the staff, which increases the friction of the handle 107 and prevents the conductive tape length measuring device from falling out of the hand and breaking, thereby extending the service life of the device;

[0030] In addition, if Figure 1 and Figure 2 As shown, a stopper 201 is fixedly provided at one end of the distance measuring ring rotating shaft 2 away from the housing 1, and the conductive tape 7 is arranged inside the stopper 201 to limit the conductive tape 7 to prevent the adhesive surface of the conductive tape 7 from being separated from the surface of the distance measuring ring 3 during the pulling process, thereby improving the use effect of the conductive tape length measuring device;

[0031] At the same time, if Figure 6 As shown, a buffer spring 8 is provided between the housing 1 and the ranging ring 3. The buffer spring 8 is sleeved on the ranging ring rotating shaft 2, which can reduce the lateral impact force on the ranging ring 3 during the pulling process of the conductive tape 7, and can also make the permanent magnet 4 and the circuit board 5 at a relatively effective sensing distance, which is beneficial for the counter 6 to collect data of the ranging ring 3.
