Abstract
The utility model discloses a central spindle structure for a center shaft, comprising a barrel, wherein a piston rod is arranged in the barrel, a guiding threaded bushing is arranged at one end of the barrel, a lower cover of the barrel, which is in fast-inserting connection with a threaded elbow, is arranged at the other end of the barrel, one end of the piston rod is arranged in the barrel in a penetrating manner, the other end of the piston rod is exposed outside the barrel, and a polyformaldehyde head is arranged at the exposed end part of the piston rod. According to the central spindle structure, the threaded elbow is adopted as a connecting part of the central spindle through fast inserting, so that the connection with a pneumatic device is facilitated, the installation is convenient and fast, and complex operation of screwed connection with the traditional nut and untoward effect are reduced.
Description
Technical field
The utility model relates to central shaft, particularly a kind of mandrel structure that is used for central shaft.
Background technique
Mandrel is the important component part of central shaft, the transmission part of whole central shaft connects Pneumatic actuator by mandrel and carries out work, traditional mandrel link is to be connected on the mandrel by the connecting head of nut with Pneumatic actuator, because the mandrel transmission makes nut loosening easily, cause central shaft to produce harmful effect.
The model utility content
The purpose of this utility model is at the above-mentioned defective of prior art, to provide a kind of mandrel structure that is used for central shaft.
Technological scheme to be solved in the utility model is: a kind of mandrel structure that is used for central shaft, comprise a cylindrical shell, be provided with piston rod in the described cylindrical shell, described cylindrical shell one end is provided with the guide thread cover, the described cylindrical shell the other end is provided with the screw thread elbow and inserts the cylindrical shell lower cover that is connected soon, one end of described piston rod is arranged in the described cylindrical shell, and the other end of described piston rod exposes outside described cylindrical shell, and in exposed piston rod end the firm head of one match is set.
As a kind of a kind of improvement that is used for the mandrel structure of central shaft of the utility model, the L type that is shaped as that described screw thread elbow is inserted soon.
Compared with prior art, a kind of advantage that is used for the mandrel structure of central shaft of the utility model is: adopt the slotting soon link as mandrel of screw thread elbow, promptly help being connected, conveniently install again, reduced troublesome operation and bad reaction that conventional nut spins with Pneumatic actuator.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below just with reference to the accompanying drawings the utility model is further described.
As shown in Figure 1, a kind of mandrel structure that is used for central shaft, comprise a cylindrical shell 1, be provided with piston rod 2 in the cylindrical shell 1, one end of cylindrical shell 1 is provided with guide thread cover 3, and cylindrical shell 1 the other end is provided with the screw thread elbow is slotting soon and is connected 4 cylindrical shell lower cover 5, and an end of piston rod 2 is arranged in the cylindrical shell 1, the other end of piston rod 2 exposes outside cylindrical shell 1, and in exposed piston rod 2 ends firm 6 of one match is set.
Wherein, the screw thread elbow is inserted 4 the L type that is shaped as soon.Adopting the screw thread elbow of L type to insert 4 soon helps the screw thread elbow and inserts 4 soon and be connected with the multi-direction of Pneumatic actuator.
