Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below with reference to Fig. 1 to Fig. 6 a kind of door in electrojet solar terms assembly of the utility model embodiment being done and describing clearly and completely further.Obviously, described embodiment is section Example of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, belongs to the scope of the utility model protection.
A kind of door in electrojet solar terms assembly, comprise throttle body 1, fixed arm 2, throttle plate pin 3, described throttle body 1 is wholely set the fitting seat 4 being convenient to throttle body 1 is installed on corresponding installation position, the swing frame 5 rotated for driving throttle plate pin 3, described fixed arm 2 is provided with for making swing frame 5 be fixed on the limited part 6 of specifying angle of swing, described fitting seat 4 comprises the face seat 41 for increasing throttle body 1 and installation position fitting area, the support rim 42 be all wholely set with face seat 41 and throttle body 1, described fixed arm 2 is wholely set on support rim 42, face seat 41 the fitting area that can increase between throttle body 1 and installation position is set, the stability that whole closure is installed is promoted further, fixed arm 2 adopts the mode be wholely set to be fixed on support rim 42, first, at the casting initial stage, the outer side wall of throttle body 1 eliminates the tie point with fixed arm 2, the tie point of fixed arm 2 is transferred on support rim 42, make the mold cavity casting this throttle body assembly only need be arranged to one, and do not need to arrange multiple die cavity being respectively used to be formed support rim 42 and fixed arm 2, not only make the cost of casting be effectively reduced, and the quality of throttle body assembly after casting is also promoted further, secondly, in use, even if swing frame 5 and idle screw 61 occur to clash into continually, this impact force also can directly be transmitted on support rim 42 by fixed arm 2, thus between the outer side wall that completely avoid fixed arm 2 and throttle body 1, there will be the problem in crack, reach the object that door in electrojet solar terms assembly promotes working life.
Because the rotating center axis of swing frame 5 is parallel with the axial direction of throttle plate pin 3, namely the peripheral force of swing frame 5 rotation is vertical with the axial direction of throttle plate pin 3, now the bearing of trend of fixed arm 2 is parallel with the axial direction of throttle plate pin 3, thus the peripheral force that swing frame 5 can be made to rotate is vertical with the bearing of trend of fixed arm 2, reach the object at utmost controlling swing frame 5 and rotate.
Fixed arm 2 is provided with tapped hole 7, described limited part 6 comprises the idle screw 61 coordinated with tapped hole 7, described idle screw 61 is provided with the bounding means 62 for preventing idle screw 61 from rotating freely around tapped hole 7, bounding means 62 comprises the nut 621 coordinated with idle screw 61, nut 621 and idle screw 61 carry out mating reaction, when idle screw 61 can rotate along tapped hole about 7, once reach ideal position, nut 621 rotates, and reaches the object that idle screw 61 carries out self-locking.
Fixed arm 2 is provided with the reinforced block 8 for strengthening tapped hole 7 structural strength near the end of limited part 6, due to the impact force between swing frame 5 and idle screw 61, the very first time will be transmitted on the hole wall of tapped hole 7, and reinforced block 8 effectively can reach the effect strengthening tapped hole 7 hole wall structure intensity.
Swing frame 5 is provided with the abutting part 9 that mutually can abut with limited part 6, abutting part 9 comprises and to be fixedly connected with swing frame 5 and outside wall energy and limited part 6 contact piece 91 of conflicting, setting up of contact piece 91 can avoid idle screw 61 and swing frame 5 that direct shock occurs, reduce the wearing and tearing of swing frame 5, improve the working life of throttle body.
Contact piece 91 be provided with can with the bearing surface 10 of idle screw 61 end abutment, as shown in Figure 7, the thickness size of bearing surface 10 is a, the diameter of idle screw 61 is b, wherein a is less than b, due in actual use, be subject to the impact of idle screw 61 material, idle screw 61 is more prone to be worn relative to contact piece 91, now the thickness size of bearing surface 10 is less than the diameter of idle screw 61, thus make both degrees of wear reach balance, play the object in working life both at utmost extending.
The above is only exemplary embodiment of the present utility model, but not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
