A combined piston belongs to the technical field of piston manufacturing. It includes a piston rod and a piston head threadedly connected with the piston rod. It is characterized in that the piston rod is provided with a raised conical threaded cone, the piston head is provided with a tapered threaded hole, and the piston rod is provided with a raised conical threaded cone. The table is connected with the taper threaded hole on the piston head. A sealant is provided at the joint between the taper threaded cone and the taper threaded hole. The utility model is reasonable and simple in structure, easy to manufacture, and convenient to use. The integral piston is designed to connect the piston rod and the piston head through a conical thread, which saves materials, is convenient to install, and improves the efficacy at the same time. A sealant is provided at the matching place of the holes, so that the utility model has better sealing performance and more reliable performance.
Description
Technical field
The utility model relates to a kind of combined piston, and especially a kind of novel combined piston that connects by tapered tread belongs to piston manufacturing technology field.
Background technique
At present, piston commonly used generally adopts integrated type, and piston rod and piston head are processed by integral material, the one-piece piston processing difficulties, and waste material, consuming time, consumptive material, the cost height, piston power is low.
The model utility content
The purpose of this utility model is exactly the deficiency that exists at above-mentioned existing piston, and a kind of novel combined piston is provided.
The purpose of this utility model is to realize like this, combined piston, comprise piston rod and the piston head that is connected with piston rod thread, it is characterized in that described piston rod is provided with the tapered tread frustum of a projection, piston head is provided with a tapered tread hole, on the piston rod projection the tapered tread frustum and piston head on the tapered tread hole be connected.
Described tapered tread frustum and cooperation place, tapered tread hole are provided with sealer.
The utility model is rational in infrastructure simply, the manufacturing is easy, easy to use, one-piece piston is designed to piston rod to be connected by tapered tread with piston head, saved material, easy for installation, also improved simultaneously effect, tapered tread frustum and cooperation place, tapered tread hole are provided with sealer, make the utility model better tightness, and performance is more reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model piston head structural representation;
Fig. 3 is the utility model piston rod construction schematic representation;
Among the figure: 1 piston rod, 2 piston heads, 3 tapered tread holes, 4 tapered tread frustums.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, be processed into the piston rod 1 that an end has the tapered tread frustum 4 of a projection at thinner bar, in the center of piston head 2 processing tapered tread hole 3, piston rod 1 is threaded by tapered tread frustum, tapered tread hole with piston head.Before spiral connects, on tapered tread hole and tapered tread frustum, be coated with sealer earlier, carry out the tapered tread frustum then and screw with tapered tread hole screw thread and be connected.Being threaded adds glue sealing, makes the utility model better tightness, and performance is more reliable.
