Embodiment
Below with reference to accompanying drawing, a kind of double door armrest that the mode of execution that the utility model relates to provides is described in detail.
Easy understand, according to the technical solution of the utility model, is not changing under connotation of the present utility model, and one of ordinary skill in the art can propose the various structures mode that can mutually replace and implementation.Therefore, following embodiment and accompanying drawing are only the exemplary illustrations to the technical solution of the utility model, and should not be considered as of the present utility model all or the restriction be considered as technical solutions of the utility model or restriction.
The orientation terms such as the up, down, left, right, before and after mentioned in this manual, front, the back side, top, bottom carry out defining relative to the structure shown in each accompanying drawing, they are relative concepts, therefore likely can residing for it diverse location, different using state and correspondingly changing.So, also these or other orientation term should be interpreted as restricted term.
Refer to shown in Fig. 1, a kind of gap retention mechanism, it comprises bearing 10, set screw nut 20, adjusting bolt 30 and friction plate 40.
Wherein the material of bearing 10 is generally plastics, and it is a square internally and round externally ring structure, and its one end is provided with two card bases 12 in order to connect, and the other end is provided with fixing stop bit sheet 14 and elasticity stop bit sheet 16.
The material of set screw nut 20 is generally steel, and it comprises an octagonal collar bases and a nut body.Wherein the size of base and the ring structure inner chamber of bearing 10 matched.There is cylindrical cavity nut body inside, and cavity is provided with left-handed thread.
Further, in different embodiments, bearing 10 and set screw nut 20 can be combined as a component: pedestal, also can realize the function of two components completely, might not be decomposed into two components.
The material of adjusting bolt 30 is generally steel, and it is the hollow structure of a both ends open.Comprise a circular lid 32 and a stud 34.Wherein lid is provided with four heavy stands 36.Bolt 34 is provided with sinistral external thread.
The material of friction plate 40 is generally plastics, and its shape is near cylindrical, and exterior surface dimension, slightly larger than adjusting bolt hollow cavity size, can be subject to certain extruding after assembling and strengthen frictional force, prevents friction plate from deviating from and occurs in the course of the work skidding; Its internal surface size and construction bolt thread size adapt, and in order to be transmitted in adjusting bolt by the mounting torque on construction bolt, realize regulatory function.
Refer to shown in Fig. 2,3, during assembling, set screw nut 20 is installed and is positioned in the inner chamber of ring structure of bearing 10.Adjusting bolt 30 and set screw nut 20 are meshed together by left-handed thread, and friction plate 40 is arranged on adjusting bolt inner chamber.
Now, the fixing stop bit sheet of bearing 10 and four heavy stands 36 of adjusting bolt 30 act on, and for ensureing the height after the assembling of this device, preventing set screw nut 20 body and adjusting bolt 30 top from producing when assembling and extrude and affect regulatory function.Elasticity stop bit sheet is suitable with fixing stop bit sheet height, but because structure is thinner, can produce resiliently deformable and cross boss in this assembling parts and working procedure, its effect prevents mechanism from getting loose in transportation process, and with the acting in conjunction of fixing stop bit sheet ensure this device assemble after height.
After having assembled, mechanism should be in impaction state, and adjusting bolt should have a boss to be stuck between fixing stop bit sheet and elasticity stop bit sheet.
Refer to shown in Fig. 4, during work, in original state, this gap retention mechanism 100 is assembled and is completely in impaction state, and its one end is connected with the first component 110 by the card base 12 of bearing 10, now, there is certain gap between this device and second component 120.
In working procedure, when construction bolt 130 inserts this gap retention mechanism 100 and starts dextrorotation, itself and friction plate 40 rub, and then friction plate 40 by torque conduction to adjusting bolt 30, drive adjusting bolt 30 dextrorotation, thread engagement is revolved owing to keeping left between adjusting bolt and set screw nut 20, under the effect of left-handed thread, adjusting bolt is ejected, at this moment this device is in swelling state, originally the gap be installed between second component 120 starts to reduce, the expansion height of adjusting bolt 30 is different with gap length, until adjusting bolt 30 lid 32 top and second component 120 are adjacent to completely.At this moment the frictional force overcome with friction plate 40 moves forward by construction bolt 130, until engage completely with the welded nut 140 on the first component 110, so, whole installation process terminates, and its end-state diagram refers to shown in Fig. 5.
The utility model is by the mode of tolerance, adopt the thread engagement regulated between stud and pedestal, achieve the adjustment connecting distance length between adjusting bolt and pedestal, thus can settle at one go realizing while two components connect, the gap-fill between two components can also being completed.And delicate structure, easy and simple to handle.
