Abstract
The invention relates to the field of an air pressure control valve, in particular to a clamping sleeve assembling piece for a pressure-maintaining connector. The clamping sleeve assembling piece comprises a clamping piece and a sleeve piece which are in cylindrical shapes; the sleeve piece is provided with an annular concave groove, and a through hole is arranged at the middle part of the concave groove on the sleeve piece; the clamping piece is provided with a through hole penetrating through the height direction of the clamping piece; the top of the clamping piece is provided with a boss which is matched with the end face of the concave groove of the sleeve piece; and the circular box is provided with two symmetrical clamping grooves. The clamping sleeve assembling piece for the pressure-maintaining connector is simple in structure and wide in adaptability range; the four clamping grooves are changed into two clamping grooves; and under the precondition of not influencing the locking strength, the service life of a work piece can be effectively prolonged, and the enterprise production cost is reduced.
Description
Technical field
The present invention relates to the pneumatic control valve field, specifically relate to a kind of cutting ferrule assembly parts that is used for the pressurize joint.
Background technique
In the existing technology, be used for the cutting ferrule assembly parts of pressurize joint, its structure comprises all being fastener 3 cylindraceous and external member 1 that external member 1 has ring-shaped depression groove 2 shown in Fig. 1-3, and the middle part of hollow slot 2 has through hole on the external member 1.Fastener 3 has the through hole that runs through fastener 3 short transverses, and the top of fastener 3 is provided with the boss that matches with external member 1 hollow slot 2 end faces, along four draw-in grooves 4 that have symmetry on the rounded boss.Gas pipeline passes from the through hole of fastener and external member, and fastener and kit card merging are exerted pressure, and utilizes four draw-in grooves that four parts that fastener top is slit into are tightened up to the inside, thereby gas pipeline is locked.
But there are some defectives in said structure, for example, through four draw-in grooves fastener top is slit into four parts, these four parts after using several times, the easy fracture, thus cause working life shorter.
Summary of the invention
To the technical problem that exists in the existing technology, the invention provides a kind of performance performance that neither hinders, can significantly improve the cutting ferrule assembly parts that is used for the pressurize joint in working life again.
To achieve these goals, the technological scheme of employing is following:
Be used for the cutting ferrule assembly parts of pressurize joint, it is characterized in that, comprise all being fastener cylindraceous and external member, said external member has the ring-shaped depression groove, and the middle part of hollow slot has through hole on the external member; Said fastener has the through hole that runs through the fastener short transverse, and the top of fastener is provided with the boss that matches with external member hollow slot end face, along two draw-in grooves that have symmetry on the rounded boss.
The present invention is used for the cutting ferrule assembly parts of pressurize joint, and simple in structure, adaptability is wider, and four draw-in grooves are designed to two, under the prerequisite that does not influence locking intensity, in the working life that can effectively improve workpiece, reduces the enterprise production cost.
Description of drawings
For the ease of it will be appreciated by those skilled in the art that the present invention is further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation that is used for the cutting ferrule assembly parts of pressurize joint in the existing technology.
Fig. 2 is the structural representation of external member among Fig. 1.
Fig. 3 is the structural representation of fastener among Fig. 1.
Fig. 4 is the structural representation of the fastener of the present invention's cutting ferrule assembly parts of being used for the pressurize joint.
Embodiment
See also Fig. 1 and 4, be used for the cutting ferrule assembly parts of pressurize joint, comprise all being fastener 3 cylindraceous and external member 1, external member 1 has ring-shaped depression groove 2, and the middle part of hollow slot 2 has through hole on the external member 1.
Fastener 3 has the through hole that runs through fastener 3 short transverses, and the top of fastener 3 is provided with the boss that matches with external member 1 hollow slot 2 end faces, along two draw-in grooves 4 that have symmetry on the rounded boss.
Gas pipeline passes from the through hole of fastener 3 and external member 1, and fastener 3 with external member 1 engaging and exert pressure, is utilized two draw-in grooves 4 that two parts that fastener 3 tops are slit into are tightened up to the inside, thereby gas pipeline is locked.
Above content only is to give an example and explanation to what structure of the present invention was done; Under the technician in present technique field described specific embodiment is made various modifications or replenish or adopt similar mode to substitute; Only otherwise depart from the structure of invention or surmount the defined scope of these claims, all should belong to protection scope of the present invention.
