Description

Technical Field

[0001] The utility model belongs to the technical field of ring main unit equipment, in particular to a retractable electronic tag. Background Art

[0002] In the operation of the disconnector of ring main unit equipment, since the disconnector operation holes of ring main unit equipment from different manufacturers are different, and the insertion depth during the operation with the operating rod is also different; when the intelligent operating device operates the disconnector, it must first align with the disconnector operation hole for code reading and confirmation.

[0003] The electronic tag is installed on one side of the disconnector operation hole. Since the operating head of the intelligent operating device needs to be adapted to the disconnector of ring main unit equipment from different manufacturers, the length of the operating head is fixed, and due to the limitation of the coil size of the intelligent operating device, and in order to prevent the intelligent operating device from misreading the code chips of other disconnectors, the code reading distance is set relatively short. When the intelligent operating device operates the disconnector for code reading, the distance between the code reading area of the intelligent operating device and the operation hole is too large, and the intelligent operating device cannot at least partially extend into the operation hole, the scanning surface of the electronic tag cannot move, and the intelligent operating device cannot stably identify the electronic tag, resulting in the inability to quickly read the code. Therefore, there is room for improvement in the existing electronic tag. Summary of the Invention

[0004] The purpose of the utility model is to improve the problem that the scanning surface of the existing electronic tag cannot move, resulting in the inability of the intelligent operating device to stably read the code, and provide a retractable electronic tag.

When an element is considered to be "provided in" another element, it can be directly provided in the other element or there can be an intermediate element at the same time.

[0044] The present utility model provides a telescopic electronic tag 100, such as Figures 1 to 4 , Figure 7As shown, it includes a telescopic member 1 and a code scanning member 3. The telescopic member 1 includes at least a first flexible portion 11 and a second flexible portion 12. A first cavity 111 is formed inside the first flexible portion 11, and a second cavity 121 is formed inside the second flexible portion 12. The first cavity 111 communicates with the second cavity 121. An air hole 14 is provided on the outer wall of the first flexible portion 11 or the second flexible portion 12, and the air hole 14 communicates with the first cavity 111 or the second cavity 121. The first flexible portion 11 or the second flexible portion 12 has an inverted conical structure. The smallest end of the first flexible portion 11 is connected to the largest end of the second flexible portion 12. The code scanning member 3 is installed at the largest end of the first flexible portion 11. The area of the largest end of the first flexible portion 11 is larger than the area of the largest end of the second flexible portion 12. Specifically, when the code scanning member 3 is far from the intelligent operation device 300, the telescopic member 1 can be stretched to move the code scanning member 3 to the code reading range of the intelligent operation device 300. After the intelligent operation device 300 reads the code, the intelligent operation device 300 extends into the operation hole 201 of the disconnecting switch 200 and presses the code scanning member 3 to make the code scanning member 3 return to its original position, and completes the opening and closing operation of the disconnecting switch 200.

[0045] Moreover, both the first flexible portion 11 and the second flexible portion 12 have an inverted conical structure. When the telescopic member 1 is compressed, the gas in the first cavity 111 and the second cavity 121 is discharged from the air hole 14, and the second flexible portion 12 and the first flexible portion 11 fold. And the area of the largest end of the first flexible portion 11 is larger than the area of the largest end of the second flexible portion 12, so that the second flexible portion 12 can be squeezed into the first flexible portion 11, and the telescopic distance between the first flexible portion 11 and the second flexible portion 12 is maximized as much as possible, so that the moving range of the code scanning member 3 is larger. When the telescopic member 1 needs to be stretched, hold the largest end of the first flexible portion 11 and pull the first flexible portion 11 to complete the stretching of the electronic tag 100. The largest end of the first flexible portion 11 increases the contact area with the hand, which is convenient for picking up. The telescopic member 1 moves the code scanning member 3 to a preset position, so that the scanning surface 31 of the code scanning member 3 moves to the code reading range of the intelligent operation device 300, enabling the intelligent operation device 300 to read the code quickly and improving the code reading efficiency.

[0046] In some embodiments, such as Figure 3 、 Figure 5As shown, the first flexible part 11 has a first support wall 112, and the second flexible part 12 has a second support wall 122. The first end of the first support wall 112 is bent to form a first support angle 101, and the first support angle 101 is less than 90 degrees. The first end of the first support wall 112 is connected to the second support wall 122. Specifically, when the first flexible part 11 squeezes the second flexible part 12, the first end of the first support wall 112 folds, the first support wall 112 deforms, and moves towards the maximum end of the first flexible part 11; the second support wall 122 also deforms and moves towards the maximum end of the first flexible part 11. The first support wall 112 and the second support wall 122 close together, realizing the contraction between the first flexible part 11 and the second flexible part 12. When the telescopic member 1 needs to be stretched, the first support wall 112 and the second support wall 122 return to their original states, and the first support angle 101 is used to support the first support wall 112.

[0047] In some embodiments, as Figure 3 、 Figure 4 shown, when the telescopic member 1 is stretched, the outer wall of the first support wall 112 or the outer wall of the second support wall 122 bulges outwards to form an outer arc surface 16; specifically, the outer arc surface 16 bulges outwards, allowing air to enter from the air holes 14 and filling the first cavity 111 and the second cavity 121, thereby supporting the first flexible part 11 and the second flexible part 12 to expand outwards, making the first flexible part 11 and the second flexible part 12 in an extended state.

[0048] When the telescopic member 1 is compressed, the outer wall of the first support wall 112 or the outer wall of the second support wall 122 sinks inwards to form an inner arc surface 17. Specifically, the inner arc surface 17 sinks inwards, the first cavity 111 and the second cavity 121 discharge the gas from the air holes 14, and a groove is formed at the bottom of the first flexible part 11 for accommodating the second flexible part 12, making the first flexible part 11 and the second flexible part 12 in a compressed state.

[0049] In some embodiments, as Figure 3 、 Figure 5 shown, the telescopic member 1 further has a third flexible part 13. A third cavity 131 is formed inside the third flexible part 13, and the third cavity 131 is communicated with the second cavity 121; the third flexible part 13 has an inverted cone-shaped structure, and the maximum end of the third flexible part 13 is installed at the minimum end of the second flexible part 12. Specifically, by providing the third flexible part 13, the telescopic range of the telescopic member 1 is larger. After the telescopic member 1 is compressed, both the third flexible part 13 and the second flexible part 12 are accommodated in the groove of the first flexible part 11, realizing the compression of the telescopic member 1.

[0050] In some embodiments, as Figure 5As shown in the figure, the third flexible part 13 has a third support wall 132 and a third cavity 131. The third cavity 131 communicates with the second cavity 121. The maximum end of the third support wall 132 is bent. A second support angle 102 is formed between the third support wall 132 and the second support wall 122, and the second support angle 102 is greater than 90 degrees. Specifically, when the second flexible part 12 presses the third flexible part 13, the second support wall 122 and the third support wall 132 are deformed and move towards the maximum end of the first flexible part 11; the second support wall 122 and the third support wall 132 close together to realize the contraction between the second flexible part 12 and the third flexible part 13. When the telescopic member 1 needs to be stretched, the second support wall 122 and the third support wall 132 return to their original states; when the telescopic member 1 is in a stretched state, the second support angle 102 is used to support the second support wall 122.

[0051] In some embodiments, the hardness of the connection between the first flexible part 11 and the second flexible part 12 is greater than the hardness of the first flexible part 11 or the second flexible part 12; at least part of the first flexible part 11 and the second flexible part 12 is made of silicone material. Specifically, when the telescopic member 1 is compressed, the first flexible part 11 and the second flexible part 12 are deformed, and the first flexible part 11 and the second flexible part 12 move closer to each other. Since they are made of silicone material themselves, they have certain telescopic properties; when the telescopic member 1 is stretched, due to the greater hardness of the connection between the first flexible part 11 and the second flexible part 12, the connection between the first flexible part 11 and the second flexible part 12 has a certain support strength, so that after the telescopic member 1 is stretched, the telescopic member 1 can maintain a relatively stable state.

[0052] In some embodiments, as Figure 3 、 Figure 4 shown, the electronic tag 100 further includes a support base 2. The support base 2 is detachably matched with the first flexible part 11; the support base 2 has a card slot 21, and the code scanning member 3 is clamped in the card slot 21. Specifically, the support base 2 is used to support the code scanning member 3, and the code scanning member 3 is accommodated in the card slot 21 to improve the stability of the code scanning member 3 on the support base 2. The support base 2 is detachably matched with the first flexible part 11. When the support base 2 and the first flexible part 11 are assembled, when stretching the electronic tag 100, the hand holds the support base 2, thereby pulling the first flexible part 11 of the telescopic member 1 to make the telescopic member 1 stretch; by providing the support base 2, it is avoided that the hand directly acts on the code scanning member 3 and the code scanning member 3 falls off from the first flexible part 11.

[0053] Preferably, as Figure 3 、 Figure 6As shown, there are at least two engaging members 22 circumferentially on the support base 2. The two engaging members 22 are arranged oppositely, and the first flexible portion 11 has a locking hole 15 for cooperating with the engaging member 22. Specifically, by setting the two engaging members 22 to cooperate with the two locking holes 15, the locking hole 15 restricts the movement of the engaging member 22 in the telescopic direction of the telescopic member 1, improving the connection stability between the support base 2 and the first flexible portion 11, and preventing the support base 2 from detaching from the first flexible portion 11 when the support base 2 is pulled.

[0054] Preferably, as Figure 3 , Figure 4 shown, the code scanning member 3 has a code reading coil 32 therein, and a scanning surface 31 is formed on the code scanning member 3. The scanning surface 31 is disposed above the code reading coil 32. Specifically, the code reading coil 32 forms a scanning area that covers the scanning surface 31; the scanning surface 31 is used for the recognition member of the intelligent operating device 300 to perform code reading recognition. When the recognition member is correctly matched with the code reading coil 32, the intelligent operating device 300 can be inserted into the knife switch 200 and perform opening and closing operations on the knife switch 200.

[0055] Preferably, as Figure 3 shown, the electronic tag 100 further includes a base 4. The smallest end of the telescopic member 1 is installed on the base 4, and the cross-sectional area of the base 4 is larger than the cross-sectional area of the smallest end of the telescopic member 1. Specifically, the base 4 is used to be installed on one side of the knife switch 200, and its installation method can be through adhesive connection. The cross-sectional area of the base 4 is larger than the cross-sectional area of the smallest end of the telescopic member 1, which is used to increase the contact area between the base 4 and the knife switch 200 and improve the stability between the base 4 and the knife switch 200.

[0056] It should be noted that the electronic tag 100 sets both the first flexible portion 11 and the second flexible portion 12 as inverted cone-shaped structures, and the area of the largest end of the first flexible portion 11 is larger than the area of the largest end of the second flexible portion 12; after the telescopic member 1 is compressed, the second flexible portion 12 can be completely accommodated within the first flexible portion 11. In other electronic tags 100, using the above-mentioned shape structures of the first flexible portion 11 and the second flexible portion 12, the electronic tag 100 has two different states, both of which are within the protection scope of this application.

[0057] When referring to the drawings for explanation, it is to explain the newly appeared features; in order to avoid repeated reference to the drawings resulting in insufficiently concise description, for the features that have been described clearly, the drawings are not cited one by one.
