Description
Technical field
The present invention relates to a kind of table legs, and in particular to a kind of telescopic table leg.
Background technique
Desk is essential furniture in people's daily life, and either home-use desk still does common table
Son, it is all indispensable, belong to a part inseparable in people's life.But these desks, as soon as have the shortcomings that it is common,
It is to be not easy to move, all gently can then needs several personal lifts than heavier or bigger, it is heavy then needing to dismantle can just move.Although city
There is the desk with pulley on face, while convenient for movement, but this desk should not be used in load-bearing, and stability is poor, safety
Coefficient is low.
Summary of the invention
The purpose of the present invention is to provide a kind of telescopic table legs, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme:
A kind of telescopic table leg, including table leg ontology and the activity feet for being set to table leg body interior, the table leg ontology
Lower part is hollow structure, and which provided activity feet, the top of the activity feet is fixedly connected with one end of lever, the company
Connecing lever is U-shaped lever, and the corner for connecting lever is fixed on the inner wall of table leg ontology, the connection thick stick by fixing axle one
The other end of bar is longer, and a gear is arranged in the corresponding position in its end, and the gear is fixed on fixing axle by unilateral bearing
On two, the fixing axle two is fixed on fixed block, and the fixed block is fixed on the inner wall of the inside of the table leg ontology；It is described
The bottom of activity feet passes through the fixed universal wheel component of fixed plate；The inside of the activity feet close to gear side setting with
The rack gear that tooth on gear is mutually twisted, the gear are that a quarter is dentation, and next a quarter is smooth shape, then under
One a quarter is tooth, and last a quarter is smooth shape, and block is arranged on the gear.
Further, the gear rotates counterclockwise.
Compared with prior art, the beneficial effects of the present invention are:
The present invention has rational design, and principle is simple, and it is convenient to operate, and feet setting hiding universal wheel can be used when moving desk
Universal wheel, time saving and energy saving, universal wheel does not affect the appearance inside feet when not needing to move, easy to use, has production letter
Single, low in cost feature.
Detailed description of the invention
Fig. 1 is the schematic diagram of internal structure one of the embodiment of the present invention；
Fig. 2 is the schematic diagram of internal structure two of the embodiment of the present invention.
In figure: 1. table leg ontologies, 2. activity feets, 3. universal wheel components, 4. gears, 5. fixing axles one, 6. connection levers,
7. rack gear, 8. fixed plates, 9. fixing axles two, 10. blocks, 11. unilateral bearings, 12. fixed blocks.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in FIG. 1 to FIG. 2, the preferred embodiment of the present invention is as follows:
A kind of telescopic table leg, including table leg ontology 1 and the activity feet 2 being set to inside table leg ontology 1, the table leg sheet
1 lower part of body is hollow structure, and which provided activity feets 2, as shown in Figure 1, the top of the activity feet 2 is fixedly connected with thick stick
One end of bar 6, the connection lever 6 are U-shaped lever, and the corner of connection lever 6 is fixed on table leg sheet by fixing axle 1
The other end of the inner wall of body 1, the connection lever 6 is longer, and a gear 4 is arranged in the corresponding position in its end, and the gear 4 is logical
It crosses unilateral bearing 11 to be fixed in fixing axle 29, the fixing axle 29 is fixed on fixed block 12, and the fixed block 12 is fixed
Inner wall in the inside of the table leg ontology 1；The bottom of the activity feet 2 passes through the fixed universal wheel component 3 of fixed plate 8, side
Just desk is pushed；The rack gear that the inside of the activity feet 2 is mutually twisted close to the setting of the side of gear 4 with the tooth on gear 4
7, it is dentation that the gear 4, which is a quarter, and next a quarter is smooth shape, next one a quarter is tooth, finally
A quarter is smooth shape, block 10 is arranged on the gear 4, as shown in Figure 2.
Further, the rotation counterclockwise of gear 4.
The operation principle of the present invention is that:
Table leg described in the present invention, the desk suitable for family are also applied for the desk of office space, and user is using
When of the invention, desktop is lifted, the gate leg can decline due to the gravity of its own, and the rack gear 7 of side can be at this time
Gear 4 interacts, and band moving gear 4 rotates, and since gear 4 is ratchet, can be blocked by gear 4 after gate leg decline
Firmly, universal wheel activity feet 2 downslide after just expose table leg ontology 1, to outside after can roll on the ground, universal wheel side
Just direction is controlled, after universal wheel exposes, the gravity of desk is held by the fixed block 12 of fixing axle 1 and fixed gear 4 at this time
Load；Move work terminate and then it is secondary lift desk upwards, will not band again after the smooth face contact of rack gear 7 and gear 4
Moving gear 4 rotates, but there are sliding frictions between gear 4, and due to the gravity of desk itself, table leg ontology 1 can decline, from
And gate leg is taken in inside table leg ontology 1 again, the stock of U-shaped lever can due to activity feet 2 moves up and under
Drop, to withstand the block 10 being arranged on gear 4, meeting after continuous decrease is so that gear 4 continues to rotate, so that gear 4
Smooth area is mobile, and the rack gear 7 of another gear area arrival activity feet 2 setting can then start next circulation.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
