Accompanying drawing explanation
The above and other feature of this utility model, character and advantage will be become apparent by the description below in conjunction with drawings and Examples, and accompanying drawing labelling identical in the accompanying drawings represents identical feature all the time, wherein:
Fig. 1 discloses the structure chart of the operating mechanism of the flameproof circuit breaker according to an embodiment of the present utility model.
Detailed description of the invention
With reference to shown in Fig. 1, the utility model proposes the operating mechanism of a kind of flameproof circuit breaker, including: handle 106, guide rail 102 and slide block 104.Handle 106 is arranged on the flameproof enclosure (not shown flameproof enclosure) of flameproof circuit breaker.Handle 106 can around the central axis of himself.In the illustrated embodiment, the main body 161 of handle 106 is cylindrical, and the top of cylindrical main body has cylinder type flameproof joint, and cylindrical main body coordinates with the flame proof circular hole (flameproof enclosure and flame proof circular hole do not illustrate) on flameproof enclosure.It will be understood to those skilled in the art that the main body of handle 106 is mounted in the flame proof circular hole on flameproof enclosure, handle 106 can rotate in flame proof circular hole, but immovable.The top of handle is by outside cylinder type flameproof joint extends to flameproof enclosure.In the illustrated embodiment, the top 163 of handle is in polygon, for instance square shown in figure.It is for the ease of operation that the top 163 of handle is designed to polygon, it is contemplated that the requirement that flame proof seals, and can there is certain resistance between flame proof circular hole and the main body of handle, and polygonal top is easy to force and handle 106 is rotated.The bottom of handle extends within flameproof enclosure.Guide rail 102 is positioned within flameproof enclosure.Slide block 104 is arranged on guide rail 102, and slide block 102 can move linearly along guide rail 104.In the illustrated embodiment, guide rail 102 is circular shaft, and slide block 104 has circular port 142, circular shaft 102 traverse circular port 142 so that slide block 104 moves along guide rail 102.In the illustrated embodiment, slide block 104 having two circular ports 142, two circular ports 142 coordinate with two guide rails 102.Two guide rails 102 be arranged in parallel so that slide block 104 can keep linearly moving.Having collar 121 on guide rail 102, collar 121 limits the slide block 104 moving range along guide rail 102.As it can be seen, be provided with two collars 121 on each guide rail 102.Slide block 104 is only capable of in the scope between two collars 121 to move.
Of the present utility model it is important that the rotation (circular motion) of handle to be converted to the rectilinear movement of slide block.In one embodiment, this conversion is realized by transformational structure.Shown in Fig. 1, the bottom of handle 106 forms extension 162, and the direction of extension 162 is vertical with handle 106, and extension 162 is formed draw-in groove 164.The top of slide block 104 has the little circular shaft 141 of projection, and little circular shaft 141 is placed in draw-in groove.When handle 106 rotates, extension 162 follows rotation, and extension 162 forms circular motion.Little circular shaft 141 is mobile in draw-in groove 164 all the time, and at draw-in groove 164 under the effect of little circular shaft 141, slide block 104 moves along guide rail 102 by being driven.Draw-in groove 164 and little circular shaft 141 form shifter.Thus, in this operating mechanism, the bottom of handle 106 is extended within flameproof enclosure and is connected with slide block 104 by transformational structure, and wherein handle 106 rotates, and transformational structure drives slide block 104 to move linearly along guide rail 102.
The position of collar 121 is determined by the rotational angle range of handle and/or the installation site of handle.The stroke making the operating mechanism that the rotational angle of handle can drive with slide block matches.In operating mechanism of the present utility model, only having handle needs to extend to outside flameproof enclosure, the structure of the axle being similar in traditional operation mechanism.And the number of elements of this operating mechanism, structure complexity are all well below gear assembly, but can provide the operational stability of similar gear assembly.
Handle is extend into the inner side of flame proof cavity by the operating mechanism of this flameproof circuit breaker by flame proof circular hole, outside turning handle at flame proof cavity, handle rotate through the rectilinear movement that shifter is converted to the slide block of flame proof inside cavity, the rectilinear movement of slide block is for driving the disjunction of chopper, this operating mechanism is novel in design, simple in construction, flexibility and reliability, less costly.
Above-described embodiment is available to be familiar with person in the art and realizes or use of the present utility model; those skilled in the art can when without departing from utility model thought of the present utility model; above-described embodiment is made various modifications or change; thus protection domain of the present utility model is not limit by above-described embodiment, and the maximum magnitude of the inventive features that claims are mentioned should be consistent with.
