Abstract
The utility model discloses a double O-shaped ring rapid plugging head. The plugging head comprises a core shaft, and two O-shaped rings are sleeved on the core shaft. The double O-shaped ring rapid plugging head is simple in structure and simple and fast to operate; the rapid plugging head is provided with two O-shaped rings, thereby being reliable in sealing; and the fractional force generated between the two O-shaped rings and the hole wall after deformation is greater than the fractional force generated by one O-shaped ring, and the plugging head is not pushed out by compressed air in a cavity, thereby being safe and reliable.
Description
Technical field
The utility model relates to engine line, specifically block head.
Background technology
The block head of now common usefulness is not to use eccentric wheel, but processes microgroove at mandrel 1 upper end (eccentric wheel position), screws on nut, during shutoff, screws nut, and mandrel is moved up.The distortion of compressing O type circle produces friction force with hole wall, reaches the purpose of shutoff.Its inefficiency when screwing nut, can drive mandrel again and rotate, and the amount of moving is not enough on the mandrel, makes the distortion of O type circle not enough, and the friction force of generation is little, and shutoff is unreliable.And when the engine assembly leak test, need the position of shutoff more, screw with nut and carry out shutoff to produce efficient very low.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, and a kind of simple in structure, easy and simple to handle, good sealing effect and the two O type circle quick blocking heads of service-strong are provided.
For realizing above-mentioned utility model purpose, the technical solution adopted in the utility model is a kind of pair of O type circle quick blocking head, comprises mandrel, is with two O type circles at mandrel.
Also be with spacer between described two O type circles.
Also comprise eccentric wheel, handle and end cap, the mandrel upper end is connected by bearing pin with eccentric wheel, and handle is installed on the eccentric wheel, and end cap is contained on the mandrel and is positioned at O type circle top.
Beneficial effect: the utility model is simple in structure; Simple to operate, fast; Two O type circles, sealing is reliable; The friction force that two O type circles distortion back and hole wall produce is bigger than the friction force that an O type circle produces, and block head can not released by the pressurized air in the chamber, and is safe and reliable.
Description of drawings
Fig. 1 is the utility model structural representation, and 8 is workpiece among the figure.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, present embodiment is being to implement under the prerequisite with technical solutions of the utility model, should understand these embodiment and only be used for explanation the utility model and be not used in restriction scope of the present utility model.
As shown in Figure 1, a kind of pair of O type circle quick blocking head comprises mandrel 1, two O type circles 2, spacer 3, eccentric wheel 4, handle 5, end cap 6 and bearing pins 7.
Handle 5 is contained on the eccentric wheel 4, and eccentric wheel 4 has open slot, mills flatly on the cylinder of mandrel 1 upper end, is contained in the open slot of eccentric wheel 4.With bearing pin 7 the two is associated in together.Be with two O type circles 2 and a spacer 3 on the mandrel 1, spacer 3 is between two O type circles 2.
Principle of work: original state is that handle is in and vertically (unclamps) position, and O type circle is free state (distortion).During shutoff, block head is inserted in the hole, move handle drive eccentric wheel and clockwise rotate, mandrel moves up under the effect of off-centre, produces thrust upwards, O type circle below promoting moves up, and then promotes spacer and move up, and the O type circle above the compression makes it distortion.Simultaneously, following O type circle is compressed deforming also, and its cylindrical is close to the workpiece hole wall, and interior circle is held mandrel tightly, and cavity is hedged off from the outer world, and reaches sealing effectiveness.
Claims (3)
1. a two O type circle quick blocking head comprises mandrel (1), it is characterized in that: be with two O type circles (2) at mandrel (1).
2. according to described pair of O type of claim 1 circle quick blocking head, it is characterized in that: also be with spacer (3) between described two O type circles (2).
3. according to described pair of O type of claim 1 circle quick blocking head, it is characterized in that: also comprise eccentric wheel (4), handle (5) and end cap (6), mandrel (1) upper end is connected by bearing pin (7) with eccentric wheel (4), handle (5) is installed on the eccentric wheel (4), and end cap (6) is sleeved on mandrel (1) upward and is positioned at O type circle (2) top.
