The core of the utility model provides a kind of locking device of flexible pipe structure, and this locking device can effectively be locked telescopic pipe, and the surface of telescopic pipe in can scratch, has effectively improved the quality and the outward appearance of flexible pipe structure.Another core of the utility model provides a kind of flexible pipe structure that comprises above-mentioned locking device.
In order to make those skilled in the art person understand the utility model scheme better, the utility model is done further to specify below in conjunction with accompanying drawing and embodiment.
Please refer to Fig. 3 and Fig. 4, Fig. 3 is the explosive view of flexible pipe structure that the utility model provides and a kind of embodiment of locking device thereof; Fig. 4 provides the sectional view of a kind of embodiment of locking device for the utility model.
The locking device 3 that the utility model provided is used for locking the interior pipe 4 of flexible pipe structure, so that make the fixed-site of interior pipe 4 and outer tube 5.This locking device 3 comprises first lock sheet 31, second lock sheet 32 and locking shell 33, and the bolt 34 of fixing first lock sheet 31 and second lock sheet 32.Wherein, locking shell 33 is fixedly connected with outer tube 5; First lock sheet 31 and second lock sheet 32 include arc tight lock part and joint; As shown in Figure 3; First lock sheet 31 comprises the first arc tight lock part 311 and first joint 312; Second lock sheet 32 comprise two arc tight lock parts that the second arc tight lock part 321 and second joint, 322, the first arc tight lock parts 311 and the second arc tight lock part 321 form cooperatively interact around interior pipe 4, and link together through two joints of first joint 312 with 322 formation of second joint.Be equipped with first through hole on two joints; Bolt 34 cooperates with tapped hole after passing two first through holes; Make the relative position of first joint 312 and second joint 312 adjustable, so make 321 of the first arc tight lock part 311 and the second arc tight lock parts around size adjustable, like this; With two arc tight lock parts can tighten in the pipe 4, also can and interior pipe 4 between have certain distance.And the bolt 34 that connects two joints passes second through hole on the locking shell 33 simultaneously, and two joints are connected with locking shell 33.Fixed-site between two joints, the position between interior pipe 4 and the locking shell 33 is also fixing, and then the fixed-site of interior pipe 4 and outer tube 5, the purpose of pipe 4 and outer tube 5 in realizing locking.
This locking device 3 can also comprise the handwheel 35 that is fixedly connected with bolt 34, and the user screws in or screw out bolt 34 through rotation hand wheel 35, realizes that internally the locking thing of pipe 4 is regulated.Handwheel 35 not only can improve the convenience of flexible pipe structure adjustment, improves user's comfort level simultaneously, can also improve the aesthetics of flexible pipe structure.
In a kind of concrete mode of execution; The locking device 3 that the utility model provided can also comprise the spring 36 around bolt 34; One end of this spring 36 acts on first lock sheet 31; The other end and second lock sheet 32 offset, and the screw-in direction of bolt 34 is by first lock sheet, 31 to second lock sheeies 32.Pipe is 4 o'clock in the locking, and bolt 34 successively screws in tapped holes through first lock sheet 31, spring 36 and second lock sheet, 32 backs, need overcome the rebounding force of spring 36, makes locking device 3 medi-springs 36 after the locking be in compressive state.When needing the extrusion of pipe 4 in the adjustment, screw out bolt 34, at this moment, the rebounding force of spring 36 can make first lock sheet 31 and second lock sheet 32 separate as early as possible, and locking device 3 is thrown off automatically, thereby improves the adjustment efficient of flexible pipe structure.
Further, locking shell 33 can be around outer tube 5, and forms cavity with the outer wall of interior pipe 4, and first lock sheet 31, second lock sheet 32 and spring 36 all are located in the cavity.As shown in Figure 3; Locking shell 33 is around outer tube 5; Form cavity as shown in the figure, first lock sheet 31, second lock sheet 32 all are located in the cavity, on the locking shell 33 two second through holes are arranged; Bolt 34 passes one second through hole, first lock sheet 31, spring 36, second lock sheet 32 successively, passes another second through hole at last.
Simultaneously, locking device 3 can also comprise the sealing cover 37 of being located at locking shell 33 bottoms, and sealing lid 37 is fixedly connected with shell removably.Sealing cover 37 can be sealed the cavity of locking shell 33, makes first lock sheet 31, second lock sheet 32 and spring 36 cleaner, avoids by outside contamination, prolongs the working life of locking device 3.
A kind of preferred embodiment in, first lock sheet 31 can be fixedly connected with locking shell 33, and articulates the parallel to an axis of drive-connecting shaft 38 and interior pipe 4 with second lock sheet 32.When bolt 34 screws in tapped holes, the joint that drives second lock sheet 32 constantly to the joint of first lock sheet 31 near, second lock sheet 32 is rotated to an angle around drive-connecting shaft 38.This structure is more reliable and more stable, can effectively reduce the possibility that skew takes place in adjusting of locking device 3, improves locking efficient.
In addition, the locking that the utility model provided can also comprise and bolt 34 nut engaged 39 that tapped hole is the tapped hole of nut 39.Be that bolt 34 matches with nut 39, pipe 4 in the locking.Obviously, tapped hole can be first through hole on second lock sheet 32, and bolt 34 when second lock sheet 32 screws in, cooperates lockedly from first lock sheet 31 with first through hole on second lock sheet 32, also can realize the purpose of the utility model.But tapped hole is arranged on the difficulty of processing that can increase second lock sheet 32 on second lock sheet 32, improves the cost of production of second lock sheet 32.And nut 39 is work commonly used, is easy to buying, and cost is low, can reduce the cost of locking device 3.
Please refer to Fig. 5, Fig. 5 is the perspective view of flexible pipe structure that the utility model provides and a kind of embodiment of locking device thereof.
Except above-mentioned locking device 3; The utility model also provides a kind of flexible pipe structure that comprises above-mentioned locking device 3; Pipe 4 and outer tube 5 in this flexible pipe structure comprises, locking shell 33 is fixedly connected with outer tube 5, and first lock sheet 31 and second lock sheet 32 are around interior pipe 4 and manage 4 in the locking as required.The structure of these other each several parts of flexible pipe structure please refer to existing technology, and this paper repeats no more.
More than flexible pipe structure and locking device thereof that the utility model provided have been carried out detailed introduction.Used concrete example among this paper the principle and the mode of execution of the utility model are set forth, above embodiment's explanation just is used to help to understand the method and the core concept thereof of the utility model.Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
