Description

Semi-closed hook claw structure of plastic housing thermostat Technical Field The utility model mainly relates to the technical field of thermostats, in particular to a semi-closed hook claw structure of a plastic shell thermostat. Background The part of the fuel oil vehicle for controlling the large and small circulation of the engine cooling system is a thermostat, the performance of the thermostat directly influences the performance of the engine, the phenomenon of overhigh temperature and even boiling of the engine is extremely easy to occur when faults occur, or the warming time is long, so that the fuel consumption is increased, most of the traditional thermostat shell materials are die-cast aluminum, along with the light weight development of automobiles, the main body materials of the thermostat are made of nylon plastics more, so that the requirement of light weight is met, and meanwhile, the strength requirement of the plastic thermostat shell is also higher and higher, so that the function of replacing an aluminum shell is achieved. The plastic thermostat with the hook claw structure is a new development trend, wherein the design of the hook claw strength is particularly critical, the hook claw strength of the traditional die casting aluminum thermostat shell is higher, the risk of fracture does not exist, but the plastic thermostat with the hook claw structure is weaker in strength, and the thermostat is easy to fracture, so that the thermostat is invalid. Disclosure of utility model The technical scheme of the utility model aims at the technical problem that the prior art is too single, provides a solution which is obviously different from the prior art, and mainly provides a semi-closed hook claw structure of a plastic shell thermostat, so as to solve the technical problem that the plastic thermostat with the hook claw structure provided in the prior art is weak in strength and easy to break, and the thermostat is invalid. The technical scheme adopted for solving the technical problems is that the semi-closed hook claw structure of the thermostat with the plastic shell comprises a thermostat shell, wherein a hand piece support and a thermostat spring are arranged in the thermostat shell. The thermostat housing comprises a hook claw, a semi-closed clamping groove for installing a hand piece support is formed in the inner wall of the hook claw, and reinforcing ribs are arranged on the outer wall of the hook claw. Further preferably, the thermostat housing includes a thermostat housing body, and the hook claw is integrally formed at a top port of the thermostat housing body. Further preferably, the hooking claws are symmetrically distributed about the vertical center line of the thermostat housing main body, the open sides of the semi-closed clamping grooves on the two hooking claws are arranged in opposite directions, and the extending ends at the two ends of the hooking claws can enter the corresponding clamping grooves through the open sides of the two clamping grooves respectively through rotating the hand piece support. Further preferably, grooves corresponding to the protruding shapes and positions of the extending ends of the two ends of the hand piece support are formed in the inner wall of the clamping groove, and stable assembly effect between the hand piece support and the clamping groove is guaranteed through cooperation of the protrusions and the grooves. Further preferably, the reinforcing ribs are distributed in an annular array along the outer wall of the hook claw, and through the arrangement of the reinforcing ribs, the structural strength and the deformation resistance of the hook claw are improved. Further preferably, one end of the thermostat spring is abutted against the opposite piece support, the other end of the thermostat spring is abutted against the inner bottom surface of the thermostat shell, and a positioning groove matched with the shape of the end of the thermostat spring is formed in the thermostat spring. Compared with the prior art, the semi-closed type hook claw structure of the plastic shell thermostat has the beneficial effects that the hook claw, the clamping groove and the reinforcing rib are adopted, the clamping groove is of the semi-closed type structure, and compared with the traditional open type hook claw clamping groove structure, the semi-closed type clamping groove can increase the strength of the hook claw while the assembly of the hand piece support and the plastic shell thermostat is not affected, and meanwhile, the reinforcing rib on the outer wall of the hook claw is matched, so that the strength of the hook claw can be enhanced, and the problem that the hook claw is weak in strength and easy to break due to plastic materials is solved. The utility model will be explained in detail below with reference to the drawings and specific embodiments.
