Abstract

The utility model provides a thermostat assembly comprising a thermostat seat and a main water outlet pipe arranged on the thermostat seat. A limit groove is formed in the inner wall of the thermostat seat, a limit block which is matched with the limit groove and used for limiting peripheral relative rotation of the main water outlet pipe and the thermostat seat is arranged inside the main water outlet pipe, and the limit block is inserted into the limit groove. The thermostat assembly has the advantages that since the limit groove is designed inside the thermostat seat and the limit block is arranged on the main water outlet pipe, when the main water outlet pipe is mounted, accurate positioning can be achieved only by axially inserting the limit block into the limit groove, a main water outlet is ensured to face accurately, and interference with external parts is avoided; fixation with multiple groups of bolts is avoided, the thermostat assembly is convenient to mount and dismount, and mounting of a thermostat is facilitated.

Description

Assembly of thermostat

Technical field

The utility model relates to engine cooling equipment and technology, relates in particular to a kind of assembly of thermostat.

Background technique

Assembly of thermostat inside is provided with thermostat, is the important component part of control engine coolant circulation system, and assembly of thermostat is by inner thermostat, and the cooling liquid of control engine is carried out the short circle of outside major cycle and internal body; When coolant temperature reaches after specified value, paraffin starts thawing and gradually becomes liquid, volume increases thereupon and oppresses rubber pipe makes its contraction, when rubber pipe shrinks, push rod is made to the thrust in order to make progress, push rod has downward reaction thrust to make valve opening to valve, and main water outlet is opened, the higher cooling liquid of temperature of assembly of thermostat inside flows out through main water outlet, via radiator, then flow back to motor through water pump, carry out major cycle; In existing assembly of thermostat, between main water outlet and thermostat base, adopt bolt to be fixedly connected with, assembly of thermostat dismounting trouble, and also inconvenient when thermostat is installed.

Model utility content

The utility model provides a kind of assembly of thermostat, for overcoming defect of the prior art, facilitates the installation of assembly of thermostat and thermostat.

The utility model provides a kind of assembly of thermostat, comprise thermostat base and be located at the primary flow pipe on described thermostat base, described thermostat base inwall is provided with restraining groove, described primary flow pipe inside is provided with and coordinates with described restraining groove and for limiting circumferentially limiting stopper in relative rotation of described primary flow pipe and described thermostat base, described limiting stopper inserts in described restraining groove.

Wherein, described primary flow pipe is provided with for limiting described primary flow pipe and the axially movable limit stoper of described thermostat base.

Further, described limit stoper is the pushing out ring being arranged on described primary flow pipe and described thermostat base.

Particularly, in described thermostat base, be provided with thermostat, described primary flow pipe inside is provided with the inner sleeve moving along described primary flow pipe bearing of trend for limiting described thermostat expansion rod, puts in described and is provided with bar hole, and the expansion rod top of described thermostat snaps in described bar hole.

The assembly of thermostat that the utility model provides at thermostat base indoor design limited location groove, is provided with limiting stopper on primary flow pipe, when primary flow pipe is installed, only limiting stopper need to be inserted vertically in restraining groove and can circumferentially locate, guarantee that main water outlet, towards accurately, avoids interfering with exterior part; Without fixing by many groups bolt, assembly of thermostat easy accessibility, has also facilitated the installation of thermostat simultaneously.

Embodiment

As shown in Fig. 1-6, the utility model provides a kind of assembly of thermostat, comprise thermostat base 1 and be located at the primary flow pipe 2 on thermostat base 1, thermostat base 1 inwall is provided with restraining groove 11, primary flow pipe 2 inside are provided with and coordinate with restraining groove 11 and for limiting circumferentially limiting stopper 21 in relative rotation of primary flow pipe 2 and thermostat base 1, limiting stopper 21 inserts in restraining grooves 11.

The assembly of thermostat that the utility model provides, at thermostat base 1 indoor design limited location groove 11, at primary flow pipe 2 inwalls, be provided with limiting stopper 21, when primary flow pipe is installed, only limiting stopper 21 need to be inserted vertically in restraining groove 11 and can limit relatively rotating of primary flow pipe 2 and thermostat base 1, realize circumferentially location, guarantee that main water outlet, towards accurately, avoids interfering with exterior part; Without fixing by many groups bolt, easy accessibility.

In the present embodiment, limiting stopper 21 is preferably located on the perisporium of primary flow pipe 2, and the shape of limiting stopper 21 can be prism-shaped or irregularly shaped.

Improvement further as above-described embodiment, when primary flow pipe internal pressure is larger, easily primary flow pipe is ejected, separated with thermostat base in order to prevent primary flow pipe, on primary flow pipe, be provided with for limiting the axially movable limit stoper of primary flow pipe and thermostat base.The structure that limit stoper can adopt circumferential locating slot to coordinate with positioning block realizes axial limiting, also can adopt the structure of pushing out ring together with directly thermostat base being held in primary flow pipe to realize.

In the present embodiment, limit stoper adopts and is arranged in the pushing out ring 3 on primary flow pipe 2 and thermostat base 1.Pushing out ring 3 is snapped on thermostat base 1, pin primary flow pipe 2.Primary flow pipe 2 is provided with boss near the position of thermostat base 1, position near described boss on thermostat base has flange, pushing out ring 3 inside have draw-in groove, in order to meet installation requirements, pushing out ring 3 can arrange and is two lobe combined types or has elasticity, by outside, inwardly boss and flange is snapped in draw-in groove.Simple in structure, be easy to dismounting.

Preferred version as above-described embodiment, in thermostat base 1, be provided with thermostat 4, primary flow pipe 2 inside are provided with the inner sleeve 22 moving along primary flow pipe bearing of trend for limiting thermostat expansion rod 41, and inner sleeve 22 is provided with bar hole 23, and thermostat expansion rod 41 tops snap in bar hole 23.

Thermostat is contained in 2 thermostat bases; Thermostat expansion rod on 3 thermostat tops inserts the bar hole 23 in primary flow pipe, as top braces, at the spacing clamp 42 of bottom thermostat, block thermostat support platform 12, when thermostat base inner loop coolant-temperature gage raises, and while reaching the expansion temperature of thermostat 3, be heated inner paraffin of thermostat 3 expands, thermostat expansion rod 41 is subject to the restriction of inner sleeve 22 because of top, thermostat spacing clamp 42 in bottom is subject to the restriction of thermostat base support platform 12, therefore the thermostat seal disc 43 of bottom is softened, and circulating water enters primary flow pipe and flows out through thermostat.Inner sleeve 22 is fixedly connected with primary flow pipe 2, and thermostat expansion rod 41 penetrates in bar hole 23, plays guiding and positioning action.
