The utility model discloses can effectively improve the fixed action of main spring during the use to strengthen the joint fastness of handle.
Description
Technical field
The utility model relates to a kind of circuit breaker accessory, and more particularly it relates to a kind of moulded case circuit breaker operation mechanism lever.
Background technology
The operating mechanism of breaker of plastic casing is as the important component part of breaker of plastic casing, and the emphasis of a kind of Shi Ge great circuit breaker producer analysis and research, the general principle of operating mechanism and primary structure in the industry public office are public.
Circuit breaker operation mechanism lever is mainly used in connecting main spring and clamping handle as the accessory that operating mechanism is important.The operating mechanism of a kind of breaker of plastic casing used in prior art is disclosed in Fig. 1, Fig. 2 is the part A enlarged drawing of Fig. 1, the connected mode of existing main spring and lever clearly can be represented by observing Fig. 1 and Fig. 2, lever is call in the industry, the body that its structure is mainly U-shaped, be installation portion in the middle of body, both sides are side plate; Installation portion is namely for connecting the position of main spring and clamping handle.Existing main spring is connected with lever mainly through arranging opening on installation portion, and main spring is extension spring, and main spring end is passed opening and is fixedly connected with for forming spacing fixed lever with installation portion.Meanwhile, for the clamping of handle, be respectively equipped with the first Access Division and the second Access Division at lever installation portion relative to the other both sides of side plate.Handle is stuck in the first Access Division and is connected with lever with on the second Access Division and side plate.
For above-mentioned existing lever, when threading off, because the active force of main spring is very large, for fixed lever but without effective location, under therefore easily causing fixed lever to be subject to the shock effect of dropout generation, there is wobble deviation, once fixed lever departs from the clasp of main spring, operating mechanism part can be caused to fall apart, circuit breaker damages and cannot use, and therefore for existing breaker of plastic casing, ensures that the fixed effect of fixed lever is very important.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of moulded case circuit breaker operation mechanism lever, effectively can improve the fixation of main spring during use, and strengthens the clamping fastness of handle.
For achieving the above object, the utility model provides following technical scheme: a kind of moulded case circuit breaker operation mechanism lever, comprise its body, its body comprises the side plate on installation portion and both sides, described installation portion is provided with the opening for installing main spring, described installation portion is respectively equipped with the first Access Division and the second Access Division relative to the other both sides of side plate, and described opening part is provided with the groove for being embedded fixed lever.
Described groove passes through punch forming.
Effect of the present utility model is, the connected mode of main spring and lever is described in detail in the introduction, seldom repeats herein.The utility model is by arranging the groove for being embedded fixed lever at opening part, fixed lever is fixed by being embedded in groove, effectively prevent it from wobble deviation occurring, and be subject to the pulling force effect of main spring, fixed lever is embedded in groove be tightened up, it cannot deviate from groove, ensure that the stationarity of its position, strengthened the fixation of main spring and lever by such scheme, improve the stability in use of breaker of plastic casing.
The utility model is set to further: described first Access Division, the second Access Division, side plate are used for being equipped with anti-slip veins with the position of handle clamping.
When making handle and lever clamping by such scheme, clamping ground is more firm, even if operating mechanism frequent movement also can ensure that handle can not depart from from lever.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of lever and main spring in prior art;
Fig. 2 is the part A enlarged drawing of Fig. 1;
Fig. 3 is the structural representation of lever in prior art;
Fig. 4 is the structural representation one of the utility model embodiment lever;
Fig. 5 is the structural representation two of the utility model embodiment lever.
Description of reference numerals: 1, lever; 2, handle; 3, main spring; 11, opening; 12, installation portion; 13, side plate; 14, the first Access Division; 15, the second Access Division; 16, groove; 17, anti-slip veins; 31, fixed lever.
Embodiment
Referring to figs. 1 through Fig. 5, the utility model embodiment is described further.
Moulded case circuit breaker operation mechanism lever described in the present embodiment, as shown in Figure 4, comprise its body, its body comprises the side plate 13 on installation portion 12 and both sides, described installation portion 12 is provided with the opening 11 for installing main spring 3, the other both sides of the relative side plate 13 of described installation portion 12 are respectively equipped with the first Access Division 14 and the second Access Division 15, and described opening 11 place is provided with the groove 16 for being embedded fixed lever 31.Opening 11 is overall rectangular, and groove 16 is vertical with opening 11.
Further, described in this, groove 16 passes through punch forming.Make the another side of installation portion 12 confronting grooves 16 form protruding reinforcing rib structure by punch forming, play the effect increasing installation portion 12 mechanical strength simultaneously.
Effect of the present utility model is, main spring 3 is described in detail in the introduction with the connected mode of lever, seldom repeats herein.The utility model is by arranging the groove 16 for being embedded fixed lever 31 at opening 11 place, fixed lever 31 is fixed by being embedded in groove 16, effectively prevent it from wobble deviation occurring, and be subject to the pulling force effect of main spring 3, fixed lever 31 is embedded in groove 16 be tightened up, it cannot deviate from groove 16, ensure that the stationarity of its position, strengthen main spring 3 and the fixation of lever by such scheme, improve the stability in use of breaker of plastic casing.
The utility model is set to further: described first Access Division 15, Access Division 14, second, side plate 13 are for being equipped with anti-slip veins 17 with the position of handle 2 clamping.
When making handle 2 and lever clamping by such scheme, clamping ground is more firm, even if operating mechanism frequent movement also can ensure that handle 2 can not depart from from lever.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, all within design concept of the present utility model, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
