[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Example 1

[0032] Reference Figure 1-6 , a structure of an ignition resistor, including: a mounting plate 1, a top cover 2, an electronic detonator chip bridge wire, an abutment component and a limit component.

[0033] First, the mounting plate 1 serves as the foundation of the entire structure, with a top cover 2 fixedly mounted on top. The interior of top cover 2 houses the electronic detonator chip bridge wire, which consists of a conductive sheet 8, a power supply chipset 9, and a heating wire 10. The power supply chipset 9 is fixedly mounted on top of the conductive sheet 8 to provide electrical energy to the heating wire 10. Two mounting feet extend from one side of the conductive sheet 8, with a heating wire 10 fixedly mounted between these two feet. The heating wire 10 serves as the primary heating element, generating heat to ignite the lead components. The model number of the electronic detonator chip bridge wire is HT-TPQS.

[0034] The design of the abutment assembly ensures that the lead component maintains close contact with the heating wire 10. This assembly includes an abutment plate 11 that slides onto the top of the mounting plate 1. This abutment plate 11 cooperates with the heating wire 10 to ensure close contact between the lead component and the heating wire 10 during ignition. To facilitate the sliding adjustment of the abutment plate 11, an L-shaped movable plate 5 is fixedly mounted on the bottom of the conductive sheet 8 and slidably connected to the top of the mounting plate 1.

[0035] Furthermore, two movable grooves 14 are defined within the mounting plate 1. A first movable rod 12 is fixedly mounted on the bottom of the L-shaped movable plate 5, and a second movable rod 13 is fixedly mounted on the bottom of the abutment plate 11. The first movable rod 12 and the second movable rod 13 respectively penetrate adjacent movable grooves 14 and are slidably connected to the inner walls of the movable grooves 14, thereby achieving smooth sliding of the L-shaped movable plate 5 and the abutment plate 11.

[0036] In order to drive the movement of the abutment plate 11 and the L-shaped movable plate 5, the bottom of the mounting plate 1 is rotatably connected to a connecting plate 18, and the two ends of the connecting plate 18 are rotatably connected to a first push-pull plate 19 and a second push-pull plate 20. The other end of the first push-pull plate 19 is rotatably connected to the first movable rod 12, and the other end of the second push-pull plate 20 is rotatably connected to the second movable rod 13. In addition, a first spring 7 is fixedly mounted on one side of the L-shaped movable plate 5, and the other end of the first spring 7 is fixedly connected to the inner wall of one side of the top cover 2. The elastic force of the first spring 7 is used to push the L-shaped movable plate 5 and the abutment plate 11 closer together, thereby ensuring close contact between the lead component and the heating wire 10.

[0037] In order to facilitate the installation and replacement of the lead components, a card slot 3 is opened on the top of the top cover 2. The card slot 3 cooperates with the heating wire 10 and the abutment plate 11 to complete the card installation of the lead components.

[0038] The present application can be used in the field of electronic detonator technology, and can also be used in other fields applicable to the present application.

[0039] Example 2

[0040] refer to Figure 1 、 2 4, 6, based on the improvement of Example 1: a structure using the electronic detonator chip bridge wire as the ignition resistor, which is applied to the field of electronic detonator technology;

[0041] In this embodiment, a limiting assembly is further added to enhance the stability and safety of the structure. The limiting assembly includes two limiting rods 16 fixedly mounted inside the top cover 2, and both limiting rods 16 are located at one end close to the abutment plate 11. The outer walls of the two limiting rods 16 are slidably sleeved with the same L-shaped baffle 15, and one end of the L-shaped baffle 15 slides through one side of the card slot 3. The outer walls of the two limiting rods 16 are both sleeved with a second spring 17, one end of the second spring 17 is fixedly connected to one side of the L-shaped baffle 15, and the other end is fixedly connected to one side of the inner wall of the top cover 2. When the abutment plate 11 moves, the L-shaped baffle 15 will be pushed synchronously, thereby achieving a limiting shielding of the lead component to prevent it from accidentally moving during the ignition process.

[0042] In order to improve the integrity and aesthetics of the overall structure, in this embodiment, a bottom cover 4 is fixedly installed at the bottom of the mounting plate 1. The bottom cover 4 is used to cover the mounting components at the bottom of the mounting plate 1, which not only protects the internal components but also makes the entire structure more compact and neat.

[0043] Furthermore, to facilitate operation of the L-shaped movable plate 5, this embodiment further includes levers 6 fixedly mounted on both sides of the L-shaped movable plate 5. One end of each lever 6 passes through both sides of the top cover 2 and is slidably connected to the top cover 2 via a sliding groove. Users can easily push the L-shaped movable plate 5 by moving the levers 6, thereby adjusting the position of the abutment plate 11 to accommodate lead components of different specifications.

[0044] When the L-shaped movable plate 5 is moved, the synchronous movement of the abutting plate 11 and the L-shaped movable plate 5 is achieved through the transmission of the first push-pull plate 19, the connecting plate 18 and the second push-pull plate 20 below. The abutting plate 11 will move synchronously with the L-shaped movable plate 5 towards or away from each other; as the L-shaped movable plate 5 is gradually pulled away, the abutting plate 11 will also gradually move away from the slot 3, and the abutting plate 11 will also push the L-shaped baffle 15 to move synchronously when moving, thereby allowing the L-shaped baffle 15 to be retracted to the top cover 2 When the heating element 10 is in the closed position, the L-shaped baffle 15 is pushed back to its original position under the rebound action of the second spring 17, thereby completing the closing and limiting of the card slot 3, and ensuring a good installation effect of the lead component. During use, the user can complete the power supply to the heating wire 10 by controlling the power supply chipset 9, thereby heating the heating wire 10 and completing the ignition of the lead component.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
