Description
Technical field
The present invention relates to a kind of expansion device.
Background technique
Existing expansion device has length-adjustable composite tube and the flexible control unit of control combination pipe, and it is used on the supports such as music stand, music stand more; Since these supports need the person's of being used stature or use habit adjust length, so need this expansion device to adjust its length by its composite tube of adjustment.U.S.'s patent of invention US 6,698,698 B1 number disclosed expansion device for example, it is one to have length-adjustable composite tube expansion device.But this composite tube has the body of one group of slide relative, an and extension and contraction control assembly that is arranged between this body, can allow these body slide relative to adjust the length of this composite tube by open this extension and contraction control assembly, and can fix the relative position of these bodys by this expansion device of locking, to keep this composite tube in adjusted length.
Yet put down in writing as the aforementioned patent document, though this expansion device can reach the effect of adjusting composite tube length, but it is to be made of and complex structure many parts, manufacture difficulty height not only, so that reduce the product yield and raise the cost, also must grip body on the other hand in the use, a handling extension and contraction control assembly, this extension and contraction control assembly of operation that could be stable causes that extremely not convenient part is also arranged in the use.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcomes the above-mentioned defective that prior art exists, and a kind of novel expansion device is provided, and it has simple structure and easy-to-use advantage.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of expansion device is characterized in that, includes a control unit and a combination body; Wherein: this control unit includes: a Brake Block, it is a box body, its inside is formed with a cavity, and has one and be communicated with register hole, the opening direction that aforementioned cavity and extraneous slide rail hole, be formed at aforementioned slide rail hole offside and brake opening perpendicular to the opening direction of aforementioned slide rail hole and register hole; One brake slipper, be to close among aforementioned Brake Block from aforementioned braking opening plug, be provided with an elastic component between its inboard and Brake Block, brake slipper has and one is communicated in the sheathed hole that is communicated with this slide rail hole and register hole, reaches at least one latch that is formed on the inwall of sheathed hole again; This composite tube includes: a slide rail body, its external diameter are the sheathed holes less than aforementioned brake slipper; Be concaved with a slide rail vertically on the external tube wall of this sliding rail tube, be formed with one group of pin-and-hole of arranging along this slide rail on this slide rail, each pin-and-hole is the latch that is matched with aforementioned brake slipper; One fit body is the register hole that is communicated in aforementioned Brake Block, and its internal diameter is the external diameter that is matched with aforementioned slide rail body.
Aforesaid expansion device, wherein the braking opening of Brake Block is positioned at the edge of register hole side, and the side is opened a suitable distance and is formed with a reinforcing component; The sheathed hole of this brake slipper is extending axially along this sheathed hole with respect to the sidewall of this latch, and on the position of this extension, be formed with one and be matched with the reinforcement cave of aforementioned Brake Block reinforcing component, and between this reinforcing component and reinforcement cave, then be equiped with a reinforcement elastic component.
Aforesaid expansion device wherein is formed with a raised line on the sheathed hole inwall of brake slipper vertically; This latch is formed on this raised line.
Aforesaid expansion device, its MR medium reinforcing elastic component is a spring; This reinforcing component is a cylinder.
Aforesaid expansion device, wherein elastic component is a spring; This fixing-assembly is a cylinder.
The present invention in use, be that this brake slipper plug is closed among Brake Block, to such an extent as to again this slide rail body is passed in regular turn the slide rail hole of this Brake Block, the sheathed hole of this brake slipper, this fit body of register hole of this Brake Block, and makes this slide rail body slide into an appropriate location; Because this elastic component is installed in the fixing-assembly and fixedly between the cave of brake slipper of aforementioned Brake Block, the elastic force that this brake slipper is subjected to this elastic component promotes, so this brake slipper moves towards the direction of the braking opening that breaks away from Brake Block, but because the sheathed hole of this brake slipper is sheathed by this slide rail body, so this brake slipper can't break away from the braking opening, and form the aspect of protruding the braking opening a little; This moment, the latch of this brake slipper inserted the pin-and-hole of slide rail body, and then has fixed the position of this slide rail body, makes it and can not slidably reciprocate between slide rail hole, sheathed hole, register hole and this fit body along with this brake slipper moves;
When adjustment length need be slided this slide rail body, then the application of force is resisted the elastic force of elastic component, the part that brake slipper is protruded the braking opening pushes back among the Brake Block, makes the latch of brake slipper leave the pin-and-hole of slide rail body, allows this slide rail body be slided once again to adjust length.After treating that length adjustment finishes, stop the application of force, make the elastic force of elastic component allow this brake slipper move towards the direction of the braking opening that breaks away from Brake Block once again, form the aspect of protruding the braking opening a little once again, simultaneously its latch also inserts the pin-and-hole of slide rail body and fixes the position of this slide rail body once again, adjusts length later to keep.
Concrete structure of the present invention and using method can be understood from the above mentioned, the purpose of adjusting length can be reached because it only need be pressed into or decontrol brake slipper, promptly can convenient and stable operating with one hand; And its structure is that the minority part by easy manufacturing is constituted, so the present invention really can provide a simple structure and expansion device easy to use.
The invention has the beneficial effects as follows to have simple structure and easy-to-use advantage.
