[0004] In the existing technology, the connection structure between the resistance measuring electrode of the electric igniter and the electric igniter is complicated. It needs to be disconnected and reconnected each time, which can easily lead to improper installation, damage to the resistance measuring electrode of the electric igniter, or even misoperation.

The top of the lower sliding head 4020201 is provided with a mounting limiting square countersunk hole 4020202. A telescopic square head 4020203 is embedded in the mounting limiting square countersunk hole 4020202. The telescopic square head 4020203 can move vertically and telescopically in the mounting limiting square countersunk hole 4020202, and the telescopic square head 4020203 can drive the lower sliding head 4020201 to rotate.

[0086] like Figure 6 As shown, the bottom of the mounting limiting square countersunk hole 4020202 is coaxially provided with an electrode telescopic hole 4020204 that passes through the sliding head 4020201. The bottom of the telescopic square head 4020203 is equipped with the top end of the resistance measuring electrode 403. The bottom end of the resistance measuring electrode 403 extends out through the electrode telescopic hole 4020204 and the electrode extension hole 40105 to the bottom of the support plate 40101.

[0087] In this embodiment, the lower adjustment unit 40202 is used to adjust the extension of the resistance measuring electrode 403, and can also provide sufficient buffer margin for the resistance measuring electrode 403 during the measurement process to avoid damage to the resistance measuring electrode 403.

[0088] As a preferred embodiment of this invention, such as Figure 6As shown, the telescopic square head 4020203 is a regular hexagonal prism or regular octagonal prism structure. This structural design facilitates the rotation of the sliding head 4020201 driven by the telescopic square head 4020203, allowing adjustment of the position of the sliding head 4020201 within the electrode mounting countersunk hole 40104, thereby adjusting the initial extension distance of the resistance measuring electrode 403. It also ensures that during the buffering telescopic process, the telescopic square head 4020203 smoothly enters the mounting limiting countersunk hole 4020202 of the sliding head 4020201.

[0089] As a preferred embodiment of this invention, such as Figure 6 As shown, the top end of the compression buffer spring 40203 is connected to the bottom end of the upper sliding head 4020105, and the bottom end of the compression buffer spring 40203 is connected to the top end of the telescopic square head 4020203. The compression buffer spring 40203 provides a clamping force to the resistance measuring electrode 403, while also allowing for a certain buffering margin.

[0090] As a preferred embodiment of this invention, such as Figure 6 As shown, the outer wall of the sliding head 4020201 has an adjusting external thread, and the inner wall of the electrode mounting countersunk hole 40104 has an adjusting internal thread. The sliding head 4020201 is installed inside the electrode mounting countersunk hole 40104 via the thread, and the height of the sliding head 4020201 inside the electrode mounting countersunk hole 40104 can be adjusted up and down. This structural design in this embodiment ensures that after adjusting the position of the sliding head 4020201, it is in a fixed position, meeting the requirements for use.

[0091] In this embodiment, the resistance measuring electrode 403 drives the telescopic square head 4020203 to move the sliding head 4020201 up and down along the electrode mounting countersunk hole 40104. Because the threaded connection has a self-locking function, after reaching the set position, the sliding head 4020201 is in a relatively fixed position.

[0092] As a preferred embodiment of this invention, such as Figure 6 As shown, multiple sets of electrode adjustment mechanisms 402 are arranged in parallel on the electrode connection frame 401, and each set of electrode adjustment mechanisms 402 includes two electrode adjustment mechanisms 402.

[0093] In this embodiment, since the number of electric igniters that generally need to be measured is not large, and the number of electric igniters 5 to be tested that are fixedly installed at one time is also not large, it is sufficient to use two electrode adjustment mechanisms 402 to measure the resistance of one electric igniter 5 at a time. This reduces the number of electrode adjustment mechanisms 402 and lowers the cost.

[0094] Example 3:

[0095] This embodiment provides a resistance measurement system for electric ignition devices, such as... Figure 7 As shown, it includes a support platform 1, a sliding mounting tray 2 placed on the support platform 1, an electrode three-dimensional moving frame 3 mounted on the support platform 1, an electrode device 4 mounted on the electrode three-dimensional moving frame 3, and the electrode three-dimensional moving frame 3 drives the electrode device 4 to move in three-dimensional direction.

[0096] The above-described structural design in this embodiment improves work efficiency and meets the requirement of installing and measuring multiple electric ignition devices 5 to be tested at one time.

[0097] As a preferred embodiment, the sliding mounting tray 2 adopts the sliding mounting tray given in embodiment 1, and the electric igniter 5 to be tested and the wire 6 of the electric igniter 5 to be tested are fixedly installed inside the sliding mounting tray 2.

[0098] As a preferred embodiment of this invention, such as Figure 7 As shown, the electrode three-dimensional moving frame 3 includes a pair of longitudinal guide rails 301 arranged parallel to each other along the longitudinal direction. A transverse guide rail 303 is mounted on the pair of longitudinal guide rails 301 via a pair of longitudinal motion drivers 302. A vertical lifting frame 305 is mounted on the transverse guide rail 303 via a transverse motion driver 304. An electrode device 4 is mounted on the lifting rod 306 inside the vertical lifting frame 305.

[0099] As a preferred embodiment, the electrode device 4 adopts the electrode device given in Embodiment 2.

[0100] Furthermore, the connecting plate 40103 in the electrode connecting frame 401 of the electrode device 4 is fixedly connected to the lifting rod 306 in the vertical lifting frame 305 of the electrode three-dimensional moving frame 3 through the connecting hole 40106.

[0101] As a preferred embodiment of this invention, such as Figure 7 As shown, a lamp holder 7 is mounted on the top of the support platform 1. The lamp holder 7 is a rail-type lamp holder, allowing the lamps to move along the rails on the lamp holder 7. Casters are provided at the bottom of the support platform 1 for easy movement.

[0102] The usage process of the electric ignition resistance measurement system in this embodiment is as follows:

[0103] Place the sliding mounting tray 2 on the top working surface of the support platform 1, place the electric igniter 5 to be tested in the mounting cavity 20402 of the electric igniter to be tested, and press it in place with the pressing cover 20403.

[0104] One of the wires 6 of all the electric igniters 5 to be tested is clamped between the first wire clamping member 20601 and the first conductive support plate 20603 of the corresponding fixed wire connecting device 206. All the fixed wire connecting devices 206 are simultaneously connected to the same first electrode seat 208, so as to realize the electrical connection and conduction of one of the wires 6 of all the electric igniters 5 to be tested to the same first electrode seat 208.

[0105] The other wire 6 of all the electric igniters 5 to be tested is clamped between the second wire clamping member 20701 and the second conductive support plate 20703 of the corresponding sliding wire connecting device 207. The sliding wire connecting device 207 is connected to the second electrode seat 209 one by one through the sliding body 210, so that the second electrode seat 209 can only be electrically connected to the other wire 6 of one electric igniter 5 to be tested at the same time.

[0106] The connecting plate 40103 in the electrode connecting frame 401 of the electrode device 4 is fixedly connected to the lifting rod 306 in the vertical lifting frame 305 of the electrode three-dimensional moving frame 3 through the connecting hole 40106, so that the electrode device 4 can move in three-dimensional space under the drive of the electrode three-dimensional moving frame 3.

[0107] During resistance measurement, a pair of adjusting heads 4020107 of the electrode device 4 are connected to a pair of terminals of the resistance tester, so that the electrode device 4 is energized for testing. The electrode device 4 is moved to be directly above the first electrode seat 208 and the second electrode seat 209. The electrode device 4 is moved downward as a whole, so that the bottom ends of a pair of resistance measuring electrodes 403 are connected to the first electrode seat 208 and the second electrode seat 209 respectively and pressed together to achieve electrical conduction. The first electrode seat 208 and the second electrode seat 209 are respectively electrically connected to the electric igniter 5 to be tested through wires 6, thereby realizing resistance measurement.

[0108] During the measurement process, the electrode device 4 remains stationary while multiple electric igniters 5 are being tested. The bottom ends of a pair of resistance measuring electrodes 403 are kept in close contact with the first electrode holder 208 and the second electrode holder 209, respectively. The drive motor 212 drives the screw 213 to rotate, which in turn causes the sliding body 210 to slide along the sliding cavity 207. During this sliding process, the conductive brush 20709 sequentially contacts different conductive contacts 20705 to achieve electrical conductivity. Each conductive contact 20705 corresponds to another wire 6 of the electric igniter 5 being tested, thus enabling individual resistance measurements of the multiple electric igniters 5.
