Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
Transmitter is generally a shell it is wrapped, and inconvenience is arranged when zeroing more, if the zeroing of the electronics in transmitter device is guided to outside the transmitter by a kind of balancing controls, then can conveniently return to zero.See also Fig. 1, based on above principle, the utility model embodiment discloses a kind of transmitter, described transmitter comprises a kind of balancing controls, described transmitter comprises shell 81, described balancing controls comprise the mechanical knob parts and are arranged at the electronics zeroing device 61 of described transmitter inside, described mechanical knob parts comprise be inserted into the regulating shaft 11 on the described shell 81 and be connected in described regulating shaft 11 and described electronics zeroing device 61 between shaft coupling 51.When operation, only need so a common screwdriver, do not need specific purpose tool, can realize zeroing function, or directly described regulating shaft 11 is stretched out outside the described shell 81, then directly turn zeroing has improved the convenience of the on-the-spot zeroing of transmitter, can make transmitter except in the situation that emptying the zeroing simultaneously, can also in the situation that any input is adjusted, greatly increase the dirigibility of adjusting.
Further, see also Fig. 1-Fig. 2, among the utility model embodiment, described regulating shaft 11 is with the cap 111 of projection, described mechanical knob parts also comprise be placed in described regulating shaft 11 with on cap one end and be affixed on the O-ring seal 21 in described cap 111 and described shell 81 outsides.Owing to having increased O-ring seal 21, can prevent that so a small amount of water in outside from entering transmitter, it be can be used in some environment that open wide, preferred described O-ring seal 21 can use O RunddichtringO or existing standard seal circle.
Further, the end that described regulating shaft 11 is connected with described shaft coupling 51 offers a pin-and-hole 113, and described mechanical knob parts also comprise the packing ring 31 and the cylinder split pin 41 that is plugged in the described regulating shaft pin-and-hole 113 that is placed on the described regulating shaft 11 and pastes described shell 81 inboards.Can better fix the axial location of described regulating shaft 11 like this, and increase packing ring 31, can produce effect prevents the wearing and tearing of shaft coupling 51 and shell 81 inboards.
Particularly, described regulating shaft 11 by on one termination, the outside of described shell 81 with the opening 112 of knob, described opening is in-line, cruciform or interior sexangle.Can use like this simple tools such as general screwdriver, allen key to operate.
Further, described balancing controls also comprise the outside that is articulated in described shell 81 and can swing the catch 71 that covers described regulating shaft 11.See also Fig. 1, among the utility model embodiment, described catch 71 is articulated in the outside of described shell 81 by screw 711, can prevent that like this balancing controls are exposed to outside, both attractive in appearance, can shield to balancing controls again, prevent that misoperation and foreign matter from entering.
