Abstract
The utility model provides a compensation structure, which comprises a cone-shaped pressing block, a pressing block, a spring screw rod and a spring, wherein the cone-shaped pressing block adopts a ring-shaped structure; the pressing block is covered on the cone-shaped pressing block; the spring is arranged between the cone-shaped pressing block and the pressing block; and the spring screw rod penetrates through the pressing block and the spring sequentially and is screwed on the cone-shaped pressing block. The utility model provides the compensation structure which can perform automatic compensation automatically and is simple in structure and small in occupied area.
Description
Technical field
The utility model relates to a kind of collocation structure, refers to especially a kind of belleville spring collocation structure for sealing.
Background technique
Plastics exist a certain amount of distortion under the impact of processing and temperature; In the structure of seal request was arranged, if keep for a long time pressure, structural member can follow the string, and reduced pretightening force, and sealing effect descends.
The model utility content
The utility model proposes a kind of collocation structure, solved in the existing structure of using seal request, if keep for a long time pressure, structural member can follow the string, and reduces pretightening force, the problem that sealing effect descends.
The technical solution of the utility model is achieved in that a kind of collocation structure, comprise taper briquetting, briquetting, spring screw mandrel, spring, described taper briquetting is cirque structure, described briquetting covers on the taper briquetting, described spring is arranged between taper briquetting and briquetting, and described spring screw mandrel passes successively briquetting and spring is tightened on the taper briquetting.
Further comprise, have groove on described taper briquetting, described spring screw mandrel is screwed in groove.
Further comprise, described spring is belleville spring, is placed in the groove of taper briquetting.
Beneficial effect: the utility model has solved the defective that exists in the background technique, by structure of the present utility model, be applicable to because of long-term work, the structural member dimensional changes that temperature variation or tired etc. causes, to realize auto-compensation, can keep for a long time pretension to structural member by this structure, to realize sealing.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is an embodiment's of the utility model cross-sectional view;
Wherein: 1, the taper briquetting; 2, briquetting; 3, the spring screw mandrel; 4, spring.
Embodiment
As shown in Figure 1, a kind of collocation structure, comprise taper briquetting 1, briquetting 2, spring screw mandrel 3, spring 4, described taper briquetting 1 is cirque structure, described briquetting 2 covers on the taper briquetting, described spring 4 is arranged between taper briquetting 1 and briquetting 2, and described spring screw mandrel 3 passes successively briquetting 2 and spring 4 is tightened on taper briquetting 1.Have groove on described taper briquetting 1, described spring screw mandrel 3 is screwed in groove.Described spring 4 is belleville springs, is placed in the groove of taper briquetting 1.
When this structure was installed, taper briquetting 1 was pressed on systematic part, and briquetting 2 use screws compress, and first mix up in advance pretightening force F, by spring screw mandrel 3 guiding, guaranteed that structure can be not stuck at the volley, and spring 4 is responsible for the auto-compensation impacting force.Work as like this systematic part due to pressure, when producing plastic deformation, discharge impacting forces by spring 4, to reach the effect of auto-compensation.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
