Technical field
The utility model relates to a kind of desk, especially a kind of liftable desk.
Technical background
The height of general desk all is upper and lowerly to regulate on the market, can not satisfy the needs of various differing heights.For overcoming this shortcoming, Chinese patent has been announced a kind of same table No. 200810062884.8, comprise desktop, the foot rest of hollow and elevating mechanism are fixed with outer tube sleeve on the foot rest, be with the upper support pipe of slippage up and down in the outer tube sleeve, the upper support pipe is connected with desktop, and upper support pipe inside is provided with a screw rod, and the screw rod bottom nut interior with being fixed on outer tube sleeve is connected, screw rod top is connected with a pair of bevel gear set, and wherein the link gear of the helical gear of horizontally set and a driving helical gear rotation is connected.Rotate link gear, screw rod is moved up and down, move, reach the purpose of lifting desktop thereby drive the upper support pipe.
This same table adopts the helical gear engaged transmission, exists installation accuracy to require the shortcoming high, that mechanism is complicated, cost is high.
Chinese patent has been announced a kind of drop table No. 200510002394.5, comprises a spindle rod, and the spindle rod below is provided with foot rest, and spindle rod is provided with some slots, and the slot outside is provided with the retaining edge; Table is connected on the spindle rod, and table is provided with the bracing frame that an end has through hole; Table is connected with spindle rod by positioning component, and positioning component comprises adjustment part and clipping block, and adjustment part is provided with screw rod, and clipping block is provided with the screw that passes with the through hole screw rod corresponding, that supply adjustment part of bracing frame.During assembling, clipping block is aligned the slot of spindle rod, adjustment part is screwed to block clipping block can make the table location.When adjusting height, unclamp adjustment part, again clipping block is aligned corresponding position, screw adjustment part and get final product.
This same table needs to determine earlier the height that good clipping block aligns when regulating height, screw adjustment part again, must operate complicated operation simultaneously by two hands.
Summary of the invention
For overcoming the above-mentioned shortcoming of prior art, the utility model provides same table a kind of simple in structure, with low cost, easy and simple to handle.
Same table comprises desktop and is used for the elevating mechanism of lifting and supporting desktop, it is characterized in that: described elevating mechanism comprises and is used to support and the fixing guide rod of desktop; Be socketed with a leader casing on the described guide rod, described guide rod and leader casing matched in clearance, described leader casing is articulated in a connector that is fixed under the described desktop; The extension of described leader casing connects a toggle mechanism, described toggle mechanism makes described leader casing rotate around the pin joint of itself and described connector, change the sleeve of described leader casing and the relative angle of described guide rod, make the sleeve and the described guide rod interlock of described leader casing or unclamp, with fixedly desktop or lifting desktop.
Further, described elevating mechanism is enclosed in the inner sleeve that is connected under the described desktop; The bottom of described guide rod is consolidated in an outer sleeve; Described inner sleeve is enclosed within the described outer sleeve.
Further, described connector comprises a brace that is enclosed within the outer position-limiting drum of described guide rod and is connected in described position-limiting drum lower end.
Further, described toggle mechanism comprises the pull bar of cross-under on the drag link sleeve on the extension of described leader casing, described pull bar is connected the spanner of the described pull bar of a liftable with described desktop junction, socket one locking spring on the described pull bar, described locking spring one end pushes against described drag link sleeve, the other end pushes against a catch that is fixed on the described pull bar.
Further again, the hinged place of described leader casing and described brace is positioned at the sleeve position of described leader casing.
Perhaps, the hinged place of described leader casing and described brace is positioned at the extension of described leader casing.
Technical conceive of the present utility model is: under the normal condition, the locking spring is in compressed state, under the effect of the restoring force of spring, leader casing is a fulcrum with the articulated section of itself and brace, drag link sleeve one end is to pressing down, sleeve one end is tilted upward, and sleeve two ends chucking guide rod relies on the sleeve of leader casing and the friction lock table height between the guide rod.
When needing to adjust table height, pull spanner, pull bar is upwards carried; The restoring force that drag link sleeve overcomes the locking spring moves upward, and guide rod is just recovered, and the sleeve sky is enclosed within on the guide rod.After only inner sleeve need being promoted to suitable height, unclamp spanner, locking spring reset, i.e. lockable table height.
The utility model only needs one hand can finish the table height adjusting, and is easy to operate, simple in structure, with low cost.

The specific embodiment
Embodiment one
With reference to Fig. 1-5
Same table comprises desktop 1 and is used for the elevating mechanism of lifting and supporting desktop 1, and described elevating mechanism comprises and is used to support and the fixing guide rod 2 of desktop 1; Be socketed with a leader casing 3 on the described guide rod 2, described guide rod 2 and leader casing 3 matched in clearance, described leader casing 3 is articulated in a connector 4 that is fixed under the described desktop 1; The extension 31 of described leader casing 3 connects a toggle mechanism, described toggle mechanism makes described leader casing 3 rotate around the pin joint of itself and described connector 4, change the sleeve 32 of described leader casing 3 and the relative angle of described guide rod 2, the sleeve 32 that makes described leader casing 3 is with described guide rod 2 interlocks or unclamp, with fixedly desktop 1 or lifting desktop 1.
Described elevating mechanism is enclosed in the inner sleeve 5 that is connected under the described desktop 1; The bottom of described guide rod 2 is consolidated in an outer sleeve 6; Described inner sleeve 5 is enclosed within the described outer sleeve 6.
Described connector comprises a brace 42 that is enclosed within the position-limiting drum 41 outside the described guide rod 2 and is connected in described position-limiting drum 41 lower ends.
Described toggle mechanism comprises the pull bar 71 of cross-under on the drag link sleeve 33 on the extension 31 of described leader casing 3, described pull bar 36 is connected the spanner 74 of the described pull bar 71 of a liftable with described desktop 1 junction, socket one locking spring 72 on the described pull bar 71, described locking spring 72 1 ends push against described drag link sleeve 33, the other end pushes against a catch 73 that is fixed on the described pull bar 71.
The hinge point of described brace 42 and described leader casing 3 is in the extension 31 of described leader casing 3.
Technical conceive of the present utility model is: under the normal condition, locking spring 72 is in compressed state, under the effect of the restoring force of spring, leader casing 3 is a fulcrum with the articulated section of itself and brace 42, drag link sleeve 33 1 ends are to pressing down, sleeve 32 1 ends are tilted upward, and sleeve 32 two ends chucking guide rod 2 relies on the sleeve 32 of leader casing 3 and the friction lock table height between the guide rod 2.
When needing to adjust table height, pull spanner 74, pull bar 71 is upwards carried; The restoring force that drag link sleeve 33 overcomes locking spring 72 moves upward, leader casing 3 times just, sleeve 32 skies are enclosed within on the guide rod 2.After only inner sleeve 5 need being promoted to suitable height, unclamp spanner 74, locking spring 72 resets, i.e. the lockable table height.
