Description
Technical field
The utility model relates to a kind of hard tube that is used for telescopic adjustment and connects retaining mechanism, especially a kind of architecture advances that is applicable to the adjusting retaining mechanism of dust collector expansion pipe.
Background technology
Application number is the invention " dust collector expansion pipe adjusting retaining mechanism " that 03113428.9 Chinese invention patent application discloses the applicant, the telescoping tube that this invention proposes is regulated the retaining mechanism dependable performance, slip phenomenon can not taken place, thereby dust catcher does not have potential safety hazard in use.But the number of spare parts that this telescoping tube is regulated retaining mechanism is many, structure is complicated, manufacturing cost is higher; The height dimension of this mechanism is bigger in addition, is installed in a side of telescoping tube, and its thickness that protrudes outer tube part is about 1/3rd of outer tube diameter, operates not convenient and not attractive in appearance.
Summary of the invention
The technical problem that will solve of the present utility model is: at the shortcoming that above prior art exists, proposes a kind of simple in structure, cost is low, the telescoping tube adjusting retaining mechanism of easy to operate and good looking appearance.
In order to solve above technical problem, telescoping tube of the present utility model is regulated retaining mechanism and is comprised the outer tube that is shaped on the enlarging linkage section, be shaped on the interior pipe of locking tooth bar and anti-rotation groove on the tube wall, the fixed cover that is inserted into outer tube enlarging linkage section and is connected with it, and the flexible retaining mechanism of pipe in regulating, the top of slide block is installed in the axial microscler through hole on the outer tube enlarging linkage section tube wall in the described retaining mechanism, the bottom is installed in the axial microscler shallow slot of fixed cover outer surface, one end of described shallow slot is shaped on a through hole, its architecture advances is: described retaining mechanism contains tooth plate, described tooth plate is installed in the shallow slot through hole of fixed cover, lower surface is shaped at least two spacings and interior pipe locks the locking teeth that the tooth bar pitch matches, during locking, the locking tooth bar between cog of pipe in described locking teeth is embedded in, the top and slide block of described tooth plate is abutted together.
Be understood that the utility model in two teeth on the tooth plate are embedded in the between cog of pipe locking tooth bar, are resisted against the upper surface of tooth plate below the slide block, thereby have very locked the relative position of interior pipe and outer tube reliably under locking state.When needs were made telescopic adjustment, as long as promote the top of slide block away from tooth plate, tooth plate just can upper and lowerly float, the locking action that do not recur, and in the case, interior pipe can arbitrarily be done to stretch, the adjusting of contracting.Adjustment finishes, and slide block resets, and retaining mechanism promptly returns to locking state.
Compared with prior art, retaining mechanism of the present utility model has two locking teeths to work at least simultaneously, so coupling mechanism force is more solid and reliable than the obvious raising of prior art, and number of spare parts is few, radial structure is compact, thereby good looking appearance.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment one.
Fig. 2 is the A-A cutaway view among Fig. 1.
Fig. 3 is the structural representation of the utility model embodiment two.

The specific embodiment
Embodiment one
As shown in Figure 1 and Figure 2, the telescoping tube of present embodiment adjusting retaining mechanism is made up of outer tube 1, interior pipe 2 and retaining mechanism, and retaining mechanism contains parts such as fixed cover 3, tooth plate 6, slide block 5, compression spring 7 and cover cap 4.Outer tube 1 and interior pipe 2 are all made with metal material, be shaped on the enlarging linkage section on the outer tube 1, and on this linkage section, be provided with the axial microscler through hole suitable with slide block 5, be shaped on locking tooth bar and anti-rotation groove on the tube wall of interior pipe 2 respectively by the extrusion process moulding, anti-rotation groove be in the locking tooth bar under, for consideration attractive in appearance also can be shaped on the transition plane of the wide 2～3mm of being in the both sides of locking tooth bar; The cross section of slide block 5 is " protruding " font, and the axial microscler through hole of the width on its top and outer tube 1 is suitable and be slightly less than the bottom, and an end of slide block 5 also is shaped on the blind hole that can place compression spring 7; The interior external diameter of fixed cover 3 is suitable with the external diameter of the internal diameter of outer tube 1 and interior pipe 2 respectively, be shaped on the suitable axial microscler shallow slot in width and slide block 5 bottoms on the outer surface, one end of this shallow slot is shaped on the through hole suitable with tooth plate 6, and inner surface is shaped on and the suitable strip projected parts of interior pipe 2 anti-rotation grooves; The lower surface of tooth plate 6 is shaped on two spacings and the identical locking teeth of interior pipe 2 locking tooth bar pitches.The upper and lower of slide block 5 is inlaid in respectively in the shallow slot of the axial microscler through hole of outer tube 2 and fixed cover 3, one end of compression spring 7 is inserted in the blind hole of slide block 5 one ends, the other end is inserted on the projection of outer tube 1 axial microscler through hole, fixed cover 3 covers on inner pipe, tooth plate 6 be installed in the through hole of fixed cover 3 two teeth on it be embedded in in the between cog of locking tooth bar of pipe 2, fixed cover 3 is inserted into the enlarging linkage section place of outer tube 1 and is connected with it, abuts against each other with outer tube 1 at locking state tooth plate 6, slide block 5 and is in the same place.When needs are made telescopic adjustment, need only and promote the top of slide block 5 away from tooth plate 6, with interior pipe 2 stretch, when contracting, tooth plate 6 fluctuates and can not play locking action, as long as unclamp slide block 5, recover locking state thereby will get back to original position at the effect sliding block 6 of spring 7 elastic force when adjustment finishes.
Embodiment two
The telescoping tube of present embodiment is regulated retaining mechanism as shown in Figure 3, Figure 4, the gauge that outer tube 1 and interior pipe 2 usefulness plastic materials are made tube wall is bigger, the difference of this retaining mechanism and embodiment one only on interior pipe 2 position of anti-slip tank be arranged on a side of locking tooth bar, such benefit be in can improving pipe 2 cross the wind area of section.Other architectural feature is identical with embodiment one, therefore will not give unnecessary details.
Obviously, design of the present utility model is very ingenious, and number of spare parts is few, compact conformation, easy to use, good looking appearance, estimates will inevitably be subjected to liking of consumer after product is gone into operation, thereby has good market prospects.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
