Abstract

The utility model relates to a but mesa elevating gear of adjusting table-board height mainly has and decides board, lifter plate, elevating system, crossbeam etc. to constitute, and its characterized in that each other has elevating system for the lifter plate that the slip dress connects and decide between the board. The lifting mechanism consists of a lifter and a positioning block, the lifter provided with a positioning brake is arranged on the lifting plate, and the positioning block is positioned on the fixed plate; the lifter comprises a rocker arm, a pull rod, a torsion spring, a guide block and the like which are arranged on a lifting plate, wherein the rocker arm provided with a positioning brake is pinned with a pin fixedly arranged on the lifting plate, the pin is wound with the torsion spring of which one end is fixed on the lifting plate and the other end is respectively arranged on the rocker arm, one end of the pull rod penetrated with the guide block is pinned with the rocker arm, the other end is a free end, and the guide block is fixedly connected with the lifting plate; the positioning block is a row of positioning teeth which are made in the hollow of the fixed plate. The table board lifting device implemented according to the technical scheme has the characteristics of reasonable design, simple structure, good processing manufacturability and convenient and stable use.

Description

A kind of table top lowering or hoisting gear
Technical field
The utility model relates to the desk structure member, particularly a kind of table top lowering or hoisting gear of adjustable platform height.
Background technology
Desk and other various workbench are one of furniture the most frequently used in office, work and the daily life.But the height of (work) platform table top that writes generally is fixed, and rare have write (work) platform and the adjusting device thereof that can regulate table surface height arbitrarily.For adapting to the needs of unconventional height workbench under certain environment, generally can only be customized specially according to actual needs.So, the one, inconvenience is arranged more, the 2nd, some waste seems.
Summary of the invention
The purpose of this utility model is to disclose a kind of lowering or hoisting gear that can regulate the table surface height arbitrarily.
For achieving the above object, the utility model proposes following technical scheme; Be that this lowering or hoisting gear mainly contains compositions such as deciding plate, lifter plate, elevating mechanism, crossbeam, it is characterized in that the lifter plate of sliding installation each other and decide to be shaped between the plate elevating mechanism.Wherein, elevating mechanism is made of lifter and location retaining, is shaped on the lifter of pulling the location and is installed on lifter plate, and the location retaining is formed on decides plate; Lifter is made up of at the rocking arm of lifter plate, pull bar, torsion spring, guide pad etc. device, be shaped on the rocker-arm roller pin of pulling the location and be connected to solid pivot pin built in lifter plate, this pivot pin has the one end to be fixed in lifter plate around the home and the other end does not place the torsion spring of rocking arm, an end that wherein places the pull bar of guide pad is pinned at rocking arm, the other end is a free end, and guide pad is fixed in lifter plate; The location retaining is to be formed on a row positioning tooth of deciding plate hollow; Pulling in the location is the also orientable pin that can slide in the retaining of location; The last end device crossbeam of lifter plate.
By the table top lowering or hoisting gear that the technical program is implemented, have reasonable in design, structure is simple and direct, processing technology good, stable characteristics easy to use.
Description of drawings
What Figure of description 1 was showed is the surface structure schematic diagram of a kind of embodiment of the utility model;
Fig. 2 is a lifter decomposition texture schematic diagram.
The specific embodiment
Now be described specifically with regard to this embodiment in conjunction with the accompanying drawings.Becoming cross section by punching of the steel plate is the lifter plate 1 of flute profile, and this board slot is built-in with the elevating mechanism that is made of rocking arm 3, pull bar 5, torsion spring 10, guide pad 4 and pivot pin 11 etc.Wherein, at three angles of rocking arm respectively punching out have pin joint pull bar one end the hole, with rocker-arm roller pin be connected to pivot pin 11 the hole, and stationary positioned pull and promptly sell 9 hole; Torsion spring 10 is had mercy on and is placed pivot pin 11, one end to be fixed in lifter plate (this example is that pull bar one end is penetrated lifter plate), and the other end does not then place the back of the body end of pin 9 or punches on rocking arm and penetrates.The pull bar middle part has placed plastic guide pad 4, guide pad is fixed in lifter plate by screw, and the pull bar free end curves 90 ° and passes the groove that is formed on lifter plate and can adorn one and mould knob and be convenient to operation (also can the slide block that this free end device one is parallel with pull bar spur up and down).Decide plate 2 and also be washed into the trough plate that has screw hole by steel plate, frid punching out simultaneously goes out the location and keeps off---and a row positioning tooth 8 that is hollow is used for holding alignment pin 9.The upper and lower side punching out of deciding plate has bound edge with containing and make-up lifter plate, and the two can be slided relatively, and above-mentioned elevating mechanism is assemblied in it.Crossbeam 7 usefulness screw devices are in the upper end of lifter plate, and crossbeam is used for fixing table top.In the use, each one will decide the both sides that plate is loaded on platform with screw respectively to this lowering or hoisting gear about in pairs promptly.When desire rising table top, only need last lift table top in, pull and promptly sell 9 and can upwards slide into along the back of tooth of positioning tooth and need the tooth position of height to get final product in the location because the elastic force of torsion spring all the time tightly the pin that will be formed on rocking arm 9 " not " in the flank of tooth, be unlikely to slippage.Otherwise, when desire reduces height, when lifting table top, upwards move the free end of pull bar, cause rocking arm along pivot pin 11 deflections and make pin 9 leave positioning tooth 8, at this moment, table top reduces height with the whereabouts of lifter plate, and when the releasing lever free end, pin 9 is placed in the positioning tooth under the elastic force effect of torsion spring.Steady for the lifting that makes table top, can and decide guide pad 4 engagements that device guiding gear between the plate 12 and its side are shaped on tooth bar at lifter plate.
