Abstract
The utility model discloses a kind of knob angle limiting structure, including housing, it is located at the rotary switch of case inside and is located at the knob of hull outside, described rotary switch is provided with swing arm and is connected with knob through housing, the position, inside edge of described knob is provided with two postive stop baffles, described housing is provided with the spacing preiection corresponding with two postive stop baffles, when turning knob angle to extreme position, the spacing preiection of housing coordinates the rotation limiting knob with the postive stop baffle of knob, so rotary switch relies on external structure to carry out spacing stress, avoid rotary switch stress excessive and damage, structure is the most practical reliably, this spacing preiection and postive stop baffle are conducive to improving the stability of knob structure simultaneously.
Description
Technical field
This utility model relates to electric switch, a kind of knob angle limiting structure being applicable to electric switch.
Background technology
Existing electric equipment products more employing knob switch carries out operating control, being typically to be directly loadable into knob electronic component in structure, rotational angle relies on the spacing, when knob forwards angle limit to of electronic component itself, the impulsive force continued firmly or rotated, electronic component is easily damaged.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of button angle limiting structure, and structure is practical reliable, is prevented effectively from the spacing stress of rotary switch excessive and damage.
In order to realize the functional requirement of such scheme, this utility model be the technical scheme is that
A kind of knob angle limiting structure, the rotary switch including housing, being located at case inside and the knob being located at hull outside, described rotary switch is provided with swing arm and is connected with knob through housing, the position, inside edge of described knob is provided with two postive stop baffles, described housing is provided with the spacing preiection corresponding with two postive stop baffles, and described postive stop baffle coordinates restriction knob to rotate in the slewing area of the swing arm of rotary switch with spacing preiection.
Preferably, one end of described postive stop baffle is connected on the edge of knob, and the other end is provided with the first rinforcement bar.
Preferably, described postive stop baffle and knob are formed in one structure.
Preferably, described spacing preiection is the raised ribs of the arc-shaped matched with knob inner side edge, and the side of described raised ribs is provided with the second rinforcement bar.
Preferably, described raised ribs and housing are formed in one structure.
Preferably, the swing arm of described rotary switch is provided with locating groove, and the bottom of described knob is provided with the trepanning mated with swing arm, is provided with the clamp corresponding with locating groove in described trepanning.
The beneficial effects of the utility model: knob angle limiting structure of the present utility model, in the inside edge of knob, postive stop baffle is set, the position coordinating knob at housing arranges the spacing preiection corresponding with postive stop baffle, when turning knob angle to extreme position, the spacing preiection of housing coordinates the rotation limiting knob with the postive stop baffle of knob, so rotary switch relies on external structure to carry out spacing stress, avoid rotary switch stress excessive and damage, structure is the most practical reliably, and this spacing preiection and postive stop baffle are conducive to improving the stability of knob simultaneously.

Detailed description of the invention
nullSee Fig. 1-4，A kind of knob angle limiting structure that this utility model provides，Choose Chargeable lighting torch as embodiment of the present utility model，Including housing 1、Rotary switch 2 and knob 3，Described housing 1 is the shell of illuminating torch，Described rotary switch 2 is fixed in housing 1，Knob 3 is arranged on the outside of housing 1，Rotary switch 2 is provided with swing arm 21 and is connected with knob 3 through housing 1，It is provided with two postive stop baffles 31 in the position, inside edge of knob 3，Described housing 1 is provided with the spacing preiection 11 corresponding with two postive stop baffles 31，When turning knob 3 angle reaches capacity position，The spacing preiection 11 of housing 1 can stop the postive stop baffle 31 of knob 3，Knob 3 is made to be rotated further，To reach to limit the effect that knob 3 rotates，So rotary switch 2 relies on postive stop baffle 31 to match with spacing preiection 11 to carry out spacing stress，Avoid rotary switch 2 stress excessive and damage，Structure is the most practical reliably，This spacing preiection 11 is conducive to improving the stability of knob 3 with the structure of postive stop baffle 31 simultaneously.
In this embodiment, one end of described postive stop baffle 31 is connected on the edge of knob 3, and the other end is provided with the first rinforcement bar 32, concrete, the edge of knob 3 is flange, and postive stop baffle 31 is fastened on the inner side of flange, this postive stop baffle 31 and knob 3 are formed in one structure, make structure more firm.
In this embodiment, described spacing preiection 11 is raised ribs, raised ribs be shaped as arc-shaped, this arc-shaped raised ribs matches with the flange of knob 3, the i.e. arc-shaped side of raised ribs is pressed close to coordinate the arc inner wall of flange, and the side of described raised ribs is provided with the second rinforcement bar 12.Preferably, described raised ribs and housing 1 are formed in one structure, make structure more firm.
In order to make knob 3 more firm with the connection of rotary switch 2, the swing arm 21 of described rotary switch 2 is provided with locating groove 211, and the bottom of described knob 3 is provided with the trepanning 33 mated with swing arm 21, is provided with the clamp 331 corresponding with locating groove 211 in described trepanning 33；Preferably, it is provided with corresponding latch at swing arm 21 sidewall with on the inwall of trepanning 33, improves the fastness that knob 3 is connected with swing arm 21 further, during assembling, insert in locating groove 211 by corresponding for the clamp 331 on knob 3, quick and easy for installation.
The above, simply this utility model is than more typical embodiment, and this utility model is not limited to above-mentioned embodiment, as long as it reaches practical function of the present utility model with identical technological means, all should belong to protection domain of the present utility model.
