Description

With lock-bit and the expansion case lid for unloading laminated structure

Technical field

The utility model belongs to technical field of automobile accessories, and in particular to a kind of with lock-bit and the expansion tank for unloading laminated structure Lid.

Background technique

Cooling system pressure in automobile needs expansion tank, when the coolant liquid in circulating cooling system is reduced, expansion tank In coolant liquid flow to circulating cooling system, make coolant liquid in circulating cooling system in supplement, in order to guarantee expansion tank Stability in use is needed on expansion tank using expansion case lid, and the expansion case lid of traditional technology is to be threaded in the expansion On case, is closed although lid may be implemented, in actual use, there can be certain pressure in expansion tank, to hold Expansion case lid is easily caused to be detached from from expansion tank, simultaneously because expansion case lid is sealed construction, so when opening due to swollen Swollen interior pressure is higher, is also easy to produce danger, so applicability and practicability are restricted.

Summary of the invention

It is reasonable and strong applicability the purpose of the utility model is to provide a kind of structure setting that there is lock-bit and unload laminated structure Expansion case lid.

It realizes that the technical solution of the utility model aim is a kind of with lock-bit and the expansion case lid for unloading laminated structure, including covers Body is fixed with internal screw thread on the inner wall of the lid, and outer cover, the outer cover and the lid are provided on the outside of the lid It is provided with gap between the top surface of body, lateral connection annulus is fixed between the bottom end of the outer cover and the outer wall of the lid, The lower sidewall of the lid is provided with lock-bit slot, the internal screw thread is in the top of the lock-bit slot, described outer The bottom of lid, which is provided with to compress, sticks up bar, it is described compress stick up the middle part of bar by rotary shaft be connected to it is described it is outer cover, supported described Pressure sticks up the bottom end of bar and is fixed with lock-bit fixture block, it is described compress to stick up be fixed with stress between bar and the lateral connection annulus and draw Spring, described compress stick up bar and are caught in lock-bit fixture block in lock-bit slot under the action of the stress tension spring and are pressed on expansion tank On outer wall, the fixed release through-hole on the lateral connection annulus, the release through-hole sticks up bar position and is arranged in a staggered manner with compressing.

It is uniformly fixed with W-shaped groove in the top surface of the lid, through-hole is fixed at the roof center of the lid, in institute The roof bottom surface for stating outer cover is fixed with inclined blocker plate outward.

It is fixed with U-loop in the side-wall outer side of the lid, is fixed on the side wall of the lid and the U-loop phase Liquid circular hole is returned in connection.

The lock-bit fixture block width is greater than the flight pitch of internal screw thread.

The utility model has the effect of positive: the structure setting of the utility model is reasonable, is provided with lock-bit fixture block and lock Position slot can be such that lid is firmly fixed on expansion cabinet, be beneficial to prevent the case where appearance is loosened or fallen off, set simultaneously It is equipped with to compress and sticks up bar, can according to need and remove lock-bit fixture block out of lock-bit slot, to will not influence lid and expansion tank The screwing operation of body, and release can be carried out, it is not easy to there is danger, use is reliable and stable, strong applicability and Practicability is good.

Detailed description of the invention

In order to be more likely to be clearly understood the content of the utility model, below according to specific embodiment and combine attached Figure, is described in further detail the utility model, in which:
