Description
The utility model relates to a kind of telescopic pipe and regulates locking device.
Telescopic pipe is one of main accessories on the vacuum cleaner, and its effect is lengthening or the length that shortens dust collector suction pipe, is convenient to operation when using vacuum cleaner and connects other dust exhaust apparatus at its port.Existing dust collector expansion pipe mainly is divided into two kinds of structural types, promptly has joint to regulate length (having level to transfer) and step-less adjustment length (stepless accent), more than two kinds of telescopic pipes on vacuum cleaner industry domestic and international market, bigger demand is arranged all.Reference is the product quality mark of the relevant telescopic pipe of advanced country in the world, wherein crucial one: telescopic pipe is stretched or shorten length in any position, it axially should be able to bear 〉=pressure or the pulling force of 30Kg behind locking and positioning, and each assembly of telescopic pipe length no change and telescopic pipe does not have distortion, cracking (promptly not having any machinery surrender).For a grade accent telescopic pipe is arranged because within it, offer the concavo-convex locking slot of location on the outer assembly pipe, help axially loaded, so quality requirements can reach fully.And with reference to some stepless accent telescopic pipes (comprising some developed countries) on the domestic and international market now, most of its design principle of product and structure can't reach above-mentioned requirements, though the product that has can reach, there is the inconvenience of the shortcoming and the operating aspect of some function of use aspects.The defective of the following some aspects of some stepless accent telescopic pipe ubiquities on the market:
1. the pressure or the pulling force＜30Kg that axially can bear after the locking is relevant with safety in utilization, is the major defect of quality aspect;
2. need execute the bigger torque of executing when telescopic pipe being locked, use inconvenience;
3. releasing force is excessive, uses inconvenience;
4. the telescopic pipe stretching, extension is bigger with the shortening kinetic damping when released state, and deficient function uses inconvenience;
5. locking is executed with release and is turn-taked number too much, the infinite place of turn-taking, and feel does not know whether are locking, release, and deficient function uses inconvenience.
Because the above defect influence of stepless accent telescopic pipe, some client often loosens the requirement of some function, ease of use aspect in the time of need be with stepless accent telescopic pipe, or simply changes original intention and with a grade accent telescopic pipe is arranged.
The purpose of this utility model is: but provide a kind of from the telescopic pipe quick lock in device that locks, intensity height, quality can reach the step-less adjustment length of international product quality standard fully.
The technical solution of the utility model is: but a kind of telescopic pipe quick lock in device of step-less adjustment length, comprise outer tube and interior pipe, the port of described outer tube is fixed with interior cover, interior cover is outer to be with outer pivoted housing and to use screw thread to be connected with outer pivoted housing, interior pipe between interior cover and the outer pivoted housing is provided with collar, and collar is compressed by the front inner wall of the front inner wall of interior cover and outer pivoted housing and all cooperates with the inclined-plane.
The further technological scheme of the utility model is: but a kind of telescopic pipe quick lock in device of step-less adjustment length, comprise outer tube and interior pipe, the port of described outer tube is fixed with interior cover, interior cover is outer to be with outer pivoted housing and to use screw thread to be connected with outer pivoted housing, interior pipe between interior cover and the outer pivoted housing is provided with collar, and collar is compressed by the front inner wall of the front inner wall of interior cover and outer pivoted housing and all cooperates with the inclined-plane; Cover embeds the outer tube internal fixation in described, and the port that the leading portion that interior cover cylindrical is provided with screw thread stretches out outer tube is connected with outer pivoted housing.
The more detailed technological scheme of the utility model is: but a kind of telescopic pipe quick lock in device of step-less adjustment length, comprise outer tube and interior pipe, the port of described outer tube is fixed with interior cover, interior cover is outer to be with outer pivoted housing and to use screw thread to be connected with outer pivoted housing, interior pipe between interior cover and the outer pivoted housing is provided with collar, and collar is compressed by the front inner wall of the front inner wall of interior cover and outer pivoted housing and all cooperates with the inclined-plane; Cover embeds the outer tube internal fixation in described, and the port that the leading portion that interior cover cylindrical is provided with screw thread stretches out outer tube is connected with outer pivoted housing; Be embedded with the tail cover between the afterbody of described outer pivoted housing and the outer tube, the tail cover is fixed with outer pivoted housing, and the outer wall of described interior cover is provided with positive stop lug boss, and positive stop lug boss passes outer tube and enters in the set circumference restraining groove of tail cover inwall; The inwall of cover is provided with guide pad in described, in the guiding groove that guide pad embedding outer wall of inner tube upper edge axial direction is offered.
The utility model has the advantages that:
1. the utility model makes the collar inclined-plane produce resiliently deformable by the interior cover that is threaded and outer pivoted housing locking collar, produces pressure behind the pipe circumference in holding tightly, thus generation stiction and play the locking and positioning effect, and self-locking property is good, the mechanical strength height.
2. after the utility model is threaded to locking state with screw thread, set up positive stop lug boss at the loose measure of executing of interior cover on a circle scope, cooperates with the spacing circumferential groove of tail cover, make its locking and release angle only in the boss scope of setting, rotating cycle is few, and is easy to use.
The utility model will be further described below in conjunction with drawings and Examples:
