[0033] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0034] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0035] A side operating mechanism of a molded case switch, such as Figure 1-4 As shown, it includes a fixing assembly and a transmission assembly, wherein the fixing assembly includes a front panel 6, a side panel 3 and a bottom panel 14 connected in sequence, as shown in FIG. Figure 5-Figure 7 As shown, when the side operating mechanism of the molded case switch is installed outside the molded case switch product, it is respectively arranged corresponding to the front, side and bottom surfaces of the molded case switch product. The side panel 3 and the bottom panel 14 are integrally bent and formed, and the front panel 6 and the side panel 3 are connected by bolts to facilitate the installation of the transmission assembly. The molded case switch includes a switch input part with the fourth axis L4 as the central axis. Specifically, the switch input part can be a driving rod 8 without an operating handle 7 installed, or an operating handle 7 installed outside the driving rod 8.

[0036] The transmission assembly includes an input shaft 1 and an output slider 2. The input shaft 1 is mounted on the side panel 3 and is provided with a rotation center axis located on the first axis L1. The output slider 2 is mounted on the front panel 6 and is located between the housing of the molded case switch product. It has a driving surface provided with an output part for driving the switch to open and close. The driving surface slides on the front of the molded case switch product to drive the operating handle 7 or the driving rod 8 of the molded case switch product to rotate so as to perform the opening, closing and re-locking operations. The input shaft 1 and the output slider 2 are in transmission cooperation, so the output slider 2 can be driven to slide by rotating the input shaft 1, and the first axis L1 is parallel to the driving surface. The input shaft 1 can cooperate with a manual operating part to form a manual side operating mechanism, or cooperate with a driving part such as a motor to form an automatic side operating mechanism, or cooperate with a clutch structure to have manual and automatic operating functions at the same time.

[0037] Furthermore, the transmission assembly includes a gear 4, which has a rotation center axis located on the second axis L2. The gear 4 cooperates with the input shaft 1 so that it can rotate around its rotation center axis under the drive of the input shaft 1; a plurality of meshing openings 202 are provided on the driving surface of the output slider 2, and a convex tooth meshing with the meshing openings 202 is provided on the outer periphery of the gear 4.

[0038] The first axis L1 is parallel to or colinear with the second axis L2.

[0039] Specifically, the input shaft 1 can be connected to the rotation center axis of the gear 4 to directly drive the gear 4 to rotate synchronously. At this time, the first axis L1 and the second axis L2 are collinear.

[0040] Specifically, you can Figure 4 As shown, the input shaft 1 and the gear 4 are transmitted through the transmission crank arm 5, and the transmission crank arm 5 is connected with the input shaft 1 in a linkage manner. The transmission crank arm 5 and the gear 4 are hinged at the third axis L3 so that when the transmission crank arm 5 rotates around the first axis L1, the gear 4 can be driven to rotate around the second axis L2. In addition, the distance between the first axis L1 and the third axis L3 is smaller than the distance between the second axis L2 and the third axis L3, so that the purpose of labor saving can be achieved. In this process, the position of the hinge shaft on the transmission crank arm 5 located on the third axis L3 relative to the gear 4 is dynamically changed, so the gear 4 is connected to the hinge shaft through the bar hole 401. The gear 4 is hingedly connected to the side panel 3 at the second axis L2.

[0041] Specifically, a slide rail assembly is installed on the bottom surface of the front panel 6, and two slide grooves are formed between the slide rail assembly and the front panel 6. The two side limits of the output slider 2 are located in the two slide grooves so that it can slide relative to the front panel 6. In this embodiment, the front panel 6 is mainly provided to facilitate the installation of the slide rail assembly. The front panel 6 may also be omitted, and the slide rail assembly may be installed on the side panel 3 through a connecting frame.

[0042] The output part for driving the switch is a driving through hole 203, and the operating handle 7 or the driving rod 8 of the switch is inserted into the driving through hole 203, so that when the output slider 2 slides, the operating handle 7 or the driving rod 8 is driven to rotate.

[0043] The front panel 6 is provided with a window 601 for the operating handle 7 or the driving rod 8 of the switch to move.

[0044] The front panel 6 is fixedly connected with a mounting plate 9, and the mounting plate 9 is provided with a connection portion connected to the switch housing. A height difference is provided between the front panel 6 and the mounting plate 9 so that a cavity for installing the slide rail assembly and the output slider 2 can be formed between the front panel 6 and the switch housing. Specifically, as Figure 3As shown, in this embodiment, the connection portion on the mounting plate 9 is a through hole, and the mounting plate 9 is detachably connected to the switch housing by a bolt. The front panel 6 and the mounting plate 9 are integrally bent and formed, and the height difference between the front panel 6 and the mounting plate 9 is a preset value, ensuring the height difference between the front panel 6 and the switch housing after being connected to the switch housing.

[0045] A connecting plate 10 is fixedly connected to one side of the front panel 6 close to the side panel 3, and the connecting plate 10 is fixedly connected to the side panel 3;

[0046] The slide rail assembly includes a first slide rail block 11 which is fixedly connected to the connecting plate 10, and a certain distance is provided between the edge of the first slide rail block 11 and the front panel 6 so that a slide groove is formed between the first slide rail block 11 and the front panel 6;

[0047] The slide rail assembly includes a second slide rail block 13 fixedly connected to the bottom surface of the front panel 6 through a cushion block 12, and the edge of the second slide rail block 13 is raised relative to the cushion block 12 to form a slide groove between the front panels 6. The slide rail assembly as a whole occupies a small space, further reducing the height difference between the front panel 6 and the switch housing.

[0048] In this embodiment, the first slide rail block 11, the cushion block 12, and the second slide rail block 13 of the slide rail assembly are fixed by threaded fasteners, and may also be fixed by other common connection structures such as welding.

[0049] The bottom panel 14 is provided with a connection portion connected to the switch housing, specifically a through hole, which can be detachably connected to the switch housing by a bolt.

[0050] The bottom panel 14 is provided with a heat dissipation window 1401 to facilitate heat dissipation of the plastic shell product.

[0051] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
