The utility model content
In order to overcome the above-mentioned technological deficiency of prior art, the utility model provides a kind of instrument and meter shell, adopts the instrument and meter of this shell can regulate the toggle switch of movement side easily, does not need movement is split out.
The technical scheme that the utility model overcomes the above-mentioned technological deficiency of prior art is: a kind of instrument and meter shell, comprise the cuboid housing, and the sidewall of described housing is provided with the plurality of movable wicket, and the little door closure of described activity is on the little door opening of housing sidewall.
The little header of described activity can be provided with outside horizontally extending rotating shaft, and described rotating shaft is inserted on the sidewall of described little door opening, thus realization activity wicket being rotationally connected with shell.
Because the utility model is being provided with little door opening and the movable wicket that covers on little door opening on the housing sidewall, little door opening is arranged on the toggle switch place of instrument and meter movement, open movable wicket, just can directly stir toggle switch, the gear of adjusting apparatus instruments and meters or other functions, so just avoided movement to be taken out the defective that just can regulate from shell under the prior art, it is very convenient to operate.
Embodiment
Referring to Fig. 1-2, the instrument and meter shell that the utility model provides comprises cuboid housing 1, and the sidewall of described housing is provided with plurality of movable wicket 6, and described movable wicket 6 covers on the little door opening of housing sidewall.
Described movable wicket 6 tops can be provided with outside horizontally extending rotating shaft, and described rotating shaft is inserted on the sidewall of described little door opening, thus realization activity wicket 6 being rotationally connected with housing 1.
The quantity of the toggle switch of common movement side is one, and correspondingly described movable wicket and wicket number of openings also are one.
The shape of described movable wicket 6 and little door opening, size and position can be provided with as required, usually all can be rectangular, when the case side surface is provided with chute, can be positioned at the top of chute or below.
Referring to Fig. 1-10, install for convenient, two clamps 4 about the utility model can also be provided with, respectively be provided with the chute of a longitudinal extension on the outside surface of described housing 1 left and right sides, the rear portion 2.1 of described chute is opened wide, the middle part about in the of 2.2 the both sides cell wall be the oblique zigzag of teeth forward, the rear portion of described each clamp 4 is the slipper that cooperates with chute, the front portion is a dop part 4.3, the inboard of described clamp slipper is inserted on the chute of the corresponding sidewall of described housing, the both sides up and down at its rear portion 4.1 are provided with teeth towards the jagged edge 7 that retreads, and are meshed with the zigzag chute wall that is in contact with it.
The A/F at described chute rear portion 2.1 generally should be greater than its middle part 2.2 width, and the middle part width generally can be greater than its anterior width, and should seamlessly transit between the different in width, and is more smooth in the time of can making clamp insert chute like this.
Described chute front portion can be the dovetail groove shape, and its transversal section is that the lining is big outer little trapezoidal.
Referring to Fig. 3-6, the slipper of described clamp generally is strip.
The rear portion 4.1 of described clamp slipper can be divided into two limits up and down, leaves the gap between two limits, can utilize the elastic deformation on two limits like this, guarantees that the clamp slipper can not blocked by the teeth at its rear portion when the chute slides forwards.
The back end outer surface 4.11 of described clamp slipper can be stepped, so that hand push.
Front portion 4.2 central authorities of described clamp slipper can be provided with the saturating groove 4.21 of a longitudinal extension, can utilize the elastic deformation of groove both sides to make the tightr of the corresponding together chute wall cooperation of clamp slipper like this, Fig. 3 has shown a kind of embodiment of this clamp.
When described chute front portion is oat tail groove structure, it is big outer little trapezoidal in corresponding that the anterior inboard transversal section that is inserted in clamp slipper in these dovetail grooves also should be, help like this preventing that clamp slippage in the chute from coming out, Fig. 4-6 has shown a kind of embodiment of this clamp.
It is little when trapezoidal outside big in the transversal section of anterior 4.2 inboards of described clamp slipper is, this slipper can be provided with vertical elongated slot 4.22 of inboard opening, the section of elongated slot can rectangular or triangle, like this when needs are pulled down clamp, can utilize the elastic deformation of elongated slot both sides, clamp is transferred to from the chute of dovetail groove shape, and with for convenience detach, Fig. 6 has provided a kind of embodiment of this elongated slot.
Referring to Fig. 3-5, the dop part 4.3 of described clamp can be any suitable shape of extending forward.For improving and the back elastic pressure of maintenance installation to device panel, the arc bouncing plate 4.33 that stuck up forward at two ends about described dop front end can be provided with, the back of this arc bouncing plate can be flat-shaped annular elastic ring 4.32, can be provided with the reinforcement bouncing plate 4.31 that has two bendings that two ends are connected to this elastic ring front and rear wall in the described annular elastic ring.Can firmly clamp be pushed away forward during installation, make the arc bouncing plate of dop part, annular elastic ring and strengthen bouncing plate and produce elastic deformation, so that all the time device panel is kept bigger pressure, the arc bouncing plate of dop front end sticks together with device panel after deformation, the acting force of its counter plate mainly concentrates on its two ends up and down, help increasing moment like this, guarantee the stable of shell.
Referring to Fig. 8 and Fig. 9, described shell antetheca can be provided with rectangular aperture 8 and other openings that can expose the movement display screen.
Referring to Fig. 1, the sidewall of described shell can be provided with the some strip bleeder vents 5.1 that are used to breathe freely.
Referring to Fig. 7, described housing back wall also can be provided with some strip bleeder vents 5.2.
Referring to Fig. 9, described housing back wall can be provided with the jack of connection terminal 3, and connection terminal 3 is plugged on this jack.
Referring to Fig. 1, Fig. 2, Fig. 7 and Fig. 8, described shell antetheca to around the chimb that extends, be used to limit shell on the device panel socket the insertion position and together clamp panel with clamp.
The using method and the beneficial effect of clamp of the present utility model are: after housing is inserted appliance outlet, chute is inserted from the chute rear aperture in the inboard of clamp slipper, clamp is pushed away forward, make the dop front end tightly withstand on the device panel inboard, chimb with the housing antetheca together is clipped in housing on the panel firmly, because the directivity of intermeshing teeth on chute and the clamp, clamp can only move forward after inserting chute, can not move backward, therefore clamp can not become flexible after clamping housing, make the installation of this instrument and meter shell on device panel not only firm, and it is very convenient, promptly save time, avoided using the defective of screw again, also can not influence attractive in appearance.
