Description

A kind of compression type slide bar
Technical field
The present invention relates to mechanical connection slide bar, specifically a kind of compression type slide bars.
Background technology
The mounting structure of existing slide bar and casing compares simple, does not occur generally for ensureing that the sliding of slide bar is smooth It largely rubs, there are certain gaps for meeting between slide bar and loop bar;But again due to being provided between the two centainly Gap when causing slide bar to move, will produce the case where rocking swing and slide bar itself rotation, the sliding of slide bar made to have some setbacks Freely, it is not very convenient to use;And when existing sliding bar outer surface still can there is a situation where fretting wear, Its service life is caused to reduce.
Invention content
The purpose of the present invention is in view of the deficienciess of the prior art, providing a kind of compression type slide bar.
Technical solution:It is of the present invention solve the problems, such as used by technical solution be:A kind of compression type slide bar, including a casing With the slide bar being sleeved in casing;The inner surface of described sleeve pipe installs its oriented internal extension rod stretched out;The extension rod prolongs It stretches direction and is directed toward the center of circle of casing, and be then provided with an extension slot compatible with extension rod position on the slide bar, this prolongs The extending direction for stretching slot is then directed toward the center of circle of slide bar;The extension rod is extend into extension slot, and the end of the extension rod Portion is additionally provided with the groove being recessed to its inside;And compression bar in one is also equipped in the groove;And the lower end of the interior compression bar It is also equipped with one between the slot bottom of groove and holds out against spring, and the other end of interior compression bar is then equipped with a ball grooves, and the rolling One rotatable ball is then installed, which exposes from ball grooves, and does not fall out in pearl slot;The interior compression bar exists It is entire sliding to compress at the slot bottom for holding out against the extension slot for making under the action of spring the ball of the end of interior compression bar be pressed on slide bar Bar.
Preferably, being also set up in the casing and at the opposed position of extension rod, there are two ball grooves;And this two The position of a ball grooves line centered on extension rod is symmetrically installed setting;And rotatable rolling is mounted in the two ball grooves Pearl, the ball expose from ball grooves, and while rolling does not fall out, and the corresponding another side of slide bar is then pressed on On the two balls being arranged.
Preferably, the ball has 3/4ths to be partially installed in ball grooves, and the part of a quarter from Expose in ball grooves, exposed portion is pressed into contact with slide bar.
Preferably, being set as oval groove-like structure at the slot bottom of the extension slot.
Advantageous effect:Compared with prior art, the present invention haing the following advantages:
(1) extension slot, the inside setting of extension rod is then accordingly arranged in setting extension rod and slide bar inside middle sleeve of the present invention Compression bar in groove installation, and holding out against spring by setting makes interior compression bar be in impaction state;And rolling is arranged in the end of interior compression bar again The combination of pearl slot and ball, makes ball be pressed at the slot bottom of extension slot, so as to compress entire slide bar, and can roll Ball design again will not interfere sliding up and down for slide bar;It will not when can guarantee that slide bar moves up and down by compressing slide bar in this way Rock swing;And itself rotation of the design limitation slide bar of extension rod and extension slot, it ensure that the steady movement of slide bar;
(2) middle sleeve of the present invention also sets up the knot there are two ball grooves and ball in the opposite of the other side of extension rod On the one hand structure can coordinate the compression of compression bar in inside, make the smooth movement of slide bar, be on the other hand pressed in the medial surface of slide bar in this way On the ball of setting, reduce the contact area with casing, reduces frictional dissipation, increase its service life.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the present invention is furture elucidated, and the present embodiment is with technical solution of the present invention Premised under implemented, it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
As shown in Figure 1, a kind of compression type slide bar, including a casing 1 and the slide bar 2 that is sleeved in casing 1;Described sleeve pipe 1 inner surface installs its oriented internal extension rod 3 stretched out;The center of circle of the extending direction direction casing 1 of the extension rod 3, and institute An extension slot 4 compatible with 3 position of extension rod is then provided on the slide bar 2 stated, the extending direction of the extension slot 4 is then directed toward cunning The center of circle of bar 2;The extension rod 3 is extend into extension slot 4, and the end of the extension rod 3 is additionally provided with to its inside The groove 5 of recess;And it is also equipped with compression bar 6 in one in the groove 5;And the slot bottom of the lower end of the interior compression bar 6 and groove 5 it Between be also equipped with one and hold out against spring 7, and the other end of interior compression bar 6 is then equipped with a ball grooves 8, and then pacifies in the ball grooves 8 Equipped with a rotatable ball 9, which exposes from ball grooves 8, and does not fall out;The interior compression bar 6 is holding out against bullet The ball 9 of the end of interior compression bar 6 is set to be pressed at the slot bottom of extension slot 4 of slide bar 2 under the action of spring 7, it is entire sliding to compress Bar 2.
Ball grooves 8 there are two being also set up in the casing 1 and at 3 opposed position of extension rod;And the two balls The position of slot 8 line centered on extension rod 3 is symmetrically installed setting;And it is mounted on rotatable ball in the two ball grooves 8 9, the ball 9 exposes from ball grooves 8, and while rolling does not fall out, and 2 corresponding another side of slide bar then compresses On the two balls 9 of setting.
The ball 9 has 3/4ths to be partially installed in ball grooves 8, and the part of a quarter is from ball grooves 8 Middle exposing, exposed portion are pressed into contact with slide bar 2;It is set as oval groove-like structure at the slot bottom of the extension slot 4.
Extension slot is then accordingly arranged in setting extension rod and slide bar inside middle sleeve of the present invention, and groove is arranged in the inside of extension rod Compression bar in installation, and holding out against spring by setting makes interior compression bar be in impaction state;And ball grooves are arranged in the end of interior compression bar again With the combination of ball, ball is made to be pressed at the slot bottom of extension slot, so as to which entire slide bar is compressed, and rotatable rolling The design of pearl will not interfere sliding up and down for slide bar again;It will not be rocked when can guarantee that slide bar moves up and down by compressing slide bar in this way It swings;And itself rotation of the design limitation slide bar of extension rod and extension slot, it ensure that the steady movement of slide bar.
Middle sleeve of the present invention also sets up the structure there are two ball grooves and ball in the opposite of the other side of extension rod, The compression that on the one hand can coordinate compression bar in inside in this way, makes the smooth movement of slide bar, is on the other hand pressed in the medial surface of slide bar and sets On the ball set, reduce the contact area with casing, reduces frictional dissipation, increase its service life.
Above-mentioned specific implementation mode is a preferred embodiment of the present invention, is not the implementation for limiting the present invention The equivalence changes made with right, the content described in all ranges of patent protection according to the present invention and modification, It should all be included within the scope of present patent application.
