Embodiment
Embodiment of the present utility model is elaborated below in conjunction with the accompanying drawings.
Embodiment one：
As depicted in figs. 1 and 2, a kind of length-adjustable table frame, including support frame 1 and table leg 2, support frame 1 include mutual
Intussusception and the first support tube 11, the support tube 12 of connecting tube 13 and second that can be slided relatively, specifically, the one of the first support tube 11
End is enclosed on the outside of the one end of connecting tube 13, and one end of the second support tube 12 is enclosed on the outside of the other end of connecting tube 13, the first support
The support tube 12 of pipe 11 and second is supported by table leg 2, and table leg 2 includes lifting column 21 and is fixedly mounted on lifting column
The feet 22 of lower end.
Lifting column 21 is using the Chinese utility model such as Application No. 201510190416.9 or 201610566413.5
Lifting column disclosed in patent, the lifting column 21 mainly includes the inner tube, the tube and the outer tube of intussusception each other, lifting column
21 top is provided with motor casing, and the bottom of motor casing is fixedly connected with the upper end of inner tube, and motor casing and the first support tube 11 or
Second support tube 12 is fixedly mounted, and motor is provided with motor casing, and the motor drives inner tube, the tube and the outer tube phase by transmission device
To sliding so as to realize that lifting column 21 drives support frame 1 to lift.
Feet 22 is that string configuration increases the area on contact ground with this, and the lower surface of feet 22 is prevented provided with least two
Skidding 221, slipmat 221 is preferred to use rubber blanket, is used for increasing feet 22 and the frictional force on ground with this, so that table frame is put
It is placed on ground and is difficult to skid.
In order to realize that the first support tube 11 and the second support tube 12 are locked with connecting tube 13 respectively, the first support tube 11
Be equipped with tumbler 14 on the second support tube 12, tumbler 14 is provided with least one using the center of rotation of tumbler 14 as axle
The eccentric wheel 141 of the heart, because the center of rotation of eccentric wheel 141 is eccentric setting and eccentric direction is away from connecting tube 13
, tumbler 14 can make the edge of eccentric wheel 141 apply pretightning force to the outer wall of connecting tube 13 when being rotated with movable eccentric wheel 141,
And the pretightning force will be also gradually increased, the edge of eccentric wheel 141 and connection with the increase of the rotational angle of tumbler 14
Frictional force between the outer wall of pipe 13 will become very big, and connecting tube 13 is pressed in the first support tube 11 or the second support tube 12
Inwall on, therefore, the edge of eccentric wheel 141 just can by the first support tube 11 and the second support tube 12 respectively with connecting tube 13
Reliable locking.
When the first support tube 11 and the second support tube 12 are under lockup state with connecting tube 13 respectively, tumbler is prevented
14 couples of users cause interference spatially, and the bottom wall of the first support tube 11 is provided with is transferred to the first support tube 11 for tumbler 14
The first through hole 111 that inside is stored, the bottom wall of the second support tube 12 is provided with is transferred to the second support tube 12 for tumbler 14
The first through hole 111 that inside is stored, is incorporated in first through hole 111 in tumbler 14 and is fitted and connected the bottom of pipe 13
During wall, the pretightning force that the edge of eccentric wheel 141 applies to the bottom wall of connecting tube 13 reaches maximum, and such tumbler 14 can be received
Receive to the inside of the first support tube 11 or the second support tube 12, it is possible to avoid space interference problem.
Tumbler 14 provided with can after tumbler 14 is transferred to the inside of the first support tube 11 or the second support tube 12 against
The block 142 at the edge of first through hole 111, by the position-limiting action of block 142, can prevent tumbler 14 to be excessively transferred to first
Tumbler 14 is caused to be not easy to be drawn out operation inside 11 or second support tube of stay tube 12.
Edge of the tumbler 14 away from the center of rotation of tumbler 14 is provided with the breach 14a stretched into for finger, or, first leads to
Edge of the hole 111 away from the center of rotation of tumbler 14 is provided with the breach 111a, breach 14a and breach 111a that are stretched into for finger shape
Shape is preferably provided with camber, in the present embodiment, while setting breach 14a and breach 111a, breach 14a and breach 111a shapes
Into approximate circle passway, the passway can stretch into the first support tube 11 or the second support tube 12 for the finger of operating personnel
Inside, consequently facilitating operator is pulled out tumbler 14 with finger, realize that the first support tube 11 and the second support tube 12 are distinguished
Unblock with connecting tube 13 is operated, and by pulling the first support tube 11, the support tube 12 of connecting tube 13 and second, just can realize table
Frame length direction elongates or shortens regulation.
Tumbler 14 is rotated with the first support tube 11 or the second support tube 12 by bolt 15 and is connected, and bolt 15 includes nut
Portion 151, the trunk portion 152 being connected with nut portion 151 and the threaded shank 153 being connected with trunk portion 152, the He of the first support tube 11
The second through hole 112 is equipped with the side wall of second support tube 12, eccentric wheel 141 is provided with the spiral shell being coaxially disposed with its center of rotation
Hole 141a, threaded shank 153 is threadedly coupled after passing through the second through hole 112 with screw 141a, 112 turns of 152 and second through hole of trunk portion
It is dynamic to coordinate, due to the plain bolt not well known in the prior art of bolt 15, and it can be by its top trunk portion 152
It is rotatably assorted with the second through hole 112 on the first support tube 11 or the second support tube 12, again can be by threaded shank 153 with turning
Moving part 14 is threadedly coupled, therefore, and bolt 15 had not only had hinge function but also the function with fixedly connected part, therefore greatly simplified
The installing component structure of tumbler 14, and bolt 15 wears mounting means also so that connector 14 is installed on the first support
It is very convenient and quick that installation operation on the support tube 12 of pipe 11 or second becomes.
As shown in figure 3, the stability in order to improve table frame, table frame includes two groups of support frames 1 be arrangeding in parallel, two groups of supports
Two first support tubes 11 in frame 1 are connected with two second support tubes 12 by connecting plate 16.
Embodiment two：
As shown in figure 3, a kind of desk, including table frame 1 and the table 3 for being fixed on the top of table frame 1, table frame 1 described here is
Table frame 1 described in embodiment one.
The utility model preferred embodiment is described above, but is not to be construed as limiting the scope of the invention.
The utility model is not only limited to above example, and its concrete structure allows to change, and those skilled in the art can be according to this
Utility model is variously modified and deformed, without departing from spirit of the present utility model, belongs to the appended power of the utility model
Profit requires defined scope.
