[0013] Fig. 3 It is an exploded view of an embodiment of the utility model. DETAILED DESCRIPTION

[0014] As Figs. 1-3As shown, this utility model embodiment is a locking component of an isolating switch operating mechanism, including a housing 10, a locking member 20 slidably disposed on the housing 10 and cooperating with a manual operating shaft 11, and a retaining spring 21 disposed between the locking member 20 and the housing 10. One end of the locking member 20 has a locking protrusion 201 that cooperates with the manual operating shaft 11. The manual operating shaft 11 is respectively provided with locking grooves 111 that cooperate with the locking protrusion 201. When the locking member 20 slides to the locked position, the locking protrusion 201 is engaged in the locking groove 111, and a limiting cooperation is formed between the locking member 20 and the manual operating shaft 11. When the locking member 20 slides to the unlocked position, the locking protrusion 201 separates from the locking groove 111, realizing free cooperation between the locking member 20 and the manual operating shaft 11. The housing 10 is provided with a cover 22 that covers the locking member 20. The cover 22 has a through hole 221 through which the locking member 20 passes. The other end of the locking member 20 passes through the through hole 221 and has a padlock hole 202 protruding outside the cover 22. The locking member is slidably disposed in the through hole of the cover, thereby facilitating the assembly of the locking member and the cover. The padlock hole on the locking member protruding outside the cover facilitates locking the locking member outside the cover, preventing unauthorized operation of the manual operating shaft, thus enhancing security. The housing 10 is provided with a positioning groove 101 that engages with a retaining spring 21. The retaining spring 21 is engaged in the positioning groove 101. The cover 22 is provided with a pressure block that presses the retaining spring 21 into the positioning groove 101. The retaining spring engages in the positioning groove of the housing, thereby facilitating the assembly of the retaining spring and the housing, making assembly more convenient.

[0015] like Fig. 2 and 3 As shown, a pull groove 203 is provided on the locking member 20 above the padlock hole 202. The pull groove on the locking member facilitates the user's pulling of the locking member, making operation more convenient. Locking member 20 has locking positioning grooves 204 and unlocking positioning grooves 205 on both sides, respectively, which cooperate with the retaining spring 21. The retaining spring 21 has an arc-shaped protrusion 211 that cooperates with the locking positioning groove 204 and unlocking positioning groove 205. When the locking member 20 slides, the arc-shaped protrusion 211 reciprocates between the locking positioning groove 204 and the unlocking positioning groove 205. The arc-shaped protrusion of the retaining spring can reciprocate between the locking and unlocking positioning grooves, ensuring reliable operation of the locking member between the locked and unlocked positions, thereby improving the working reliability of the locking assembly. The housing 10 has a sliding hole 102, and the locking member 20 passes through the sliding hole 102, forming a sliding connection between the locking member 20 and the housing 10. The locking element is inserted into the sliding hole of the housing, which facilitates the assembly of the locking element with the housing and ensures that the locking element can operate reliably within the housing.

[0016] The locking member is arranged on the shell and cooperates with the manually operated shaft. When the locking member is slid to the locking position, the locking protrusion of the locking member is engaged in the locking groove of the manually operated shaft, and the manually operated shaft cannot rotate, so that the locking of the locking member and the manually operated shaft is realized, and the manually operated shaft is prevented from being randomly operated by others, and the safety is higher. Therefore, the locking assembly of the isolator operating mechanism has the advantages of simple structure, stable and reliable performance, safe and reliable, and convenient assembly.
