Description

Rack elevator

Technical field

The utility model relates to a kind of kitchen and other higher position and the rack elevator that needs the locker of easy of rise to use.

Background technology

At present, along with the raising of people's living standard and the development of indoor decoration industry, in the kitchen in some rooms, begin to be provided with locker.In order to make full use of the space, what have is installed in locker higher position, and makes it can lifting, is beneficial to and gets thing in cabinet.According to incompletely statistics, the version of the lowering or hoisting gear of existing locker is more.As the foreign patent reported in literature; the clear 61-154610 of Japan is disclosed to be directly to drive spring and inflator by connecting rod; but spring and inflator are exposed to the outside; there is not the housing protection; use dangerous; be subjected to its structural limitations, spring and inflator can't be placed in rational position, are difficult for obtaining desirable buffering effect.Disclosed in Japanese kokai publication hei-No. 148031 communique is to have increased linkage, drives energy storage and buffering original paper, though effect is preferably arranged, has increased original paper, has improved the cost of device.Also have some reports, disclosed as Chinese patent 97190057.4 is the liftable supporter that has the interlock swivel plate, though buffering effect is stable, structure is still complicated, and cost is higher.The lowering or hoisting gear of existing locker haves much room for improvement.

Summary of the invention

The purpose of this utility model provides a kind of rack elevator, and it makes simple, and compared with prior art part reduces, and cost reduces, and stressed distribution is more reasonable, has improved the security reliability that this device uses, and has prolonged service life.

The purpose of this utility model is achieved in that this device comprises locker and its interior magazine and left side thereof of assembling, a right parallel rod and a left side, right lifting controller, wherein by housing and assemble its inner or outside protective baffle plate, assemble the lifting controller that its inner damping buffer and spring constitute, be packed in the left side of locker respectively, on the right inwall, drive connecting rod in each parallel rod and follower link upper end are hinged on the both sides of magazine respectively, the sidewall of the relative connecting rod of housing is provided with cambered way, the interstitial hole of drive connecting rod lower end is packed in the central rotating shaft end that stretches out housing sidewall, hole is affixed with the last removable pin axle head that stretches out the housing cambered way on it, hole is affixed with the following removable pin axle head that stretches out the housing cambered way down for it, the last active pin shaft other end is hinged on the spring lower end that is arranged at the housing upper wall, the following active pin shaft other end is hinged on the cylinder body lower end of damping buffer, and the cylinder body upper end is hinged on the fixed axis of housing.

The two ends of above-mentioned housing cambered way are provided with the snubber block of link motion terminal point respectively.

Above-mentioned assemble case inside or outside protective baffle plate are sleeved on the central rotating shaft.

Because the drive connecting rod lower end of the utility model lowering or hoisting gear parallel rod utilizes three axis holes such as the centre bore on it, last hole, following hole, respectively with the central rotating shaft end that stretches out housing sidewall of lifting controller and to stretch out the upper and lower removable pin axle head of housing cambered way affixed, so the stressed distribution of drive connecting rod is more reasonable, improve the security reliability that this device uses, prolonged service life.Be assembled in lifting controller enclosure interior or outside protective baffle plate, can have prevented that foreign matter from entering in the housing from cambered way.Cambered way on the housing can guarantee that damping buffer and spring move by the running orbit of setting, and to produce desirable energy storage and buffering effect, make the steady lifting of magazine.The location block body of upper and lower extreme position when the cambered way two ends on the housing also can be used as the drive connecting rod motion simultaneously.If install soft cushion pad additional, can also guarantee that this device steadily locatees in the lifting final position at the two ends of cambered way.

Specific implementation method

Describe the utility model concrete structure and operating position in detail according to Fig. 1～9.Parts such as left and right parallel rod that this device comprises magazine 2 in it of locker 1 and assembling, be made up of drive connecting rod 3 and follower link 7 and left and right lifting controller 4.Wherein specification, shape and the installation site of locker 1 and its interior magazine 2 of assembling should be determined by concrete instructions for use.Lifting controller 4 is to be made of housing 16, assemble case 16 inside or outside protective baffle plate 19, the damping buffer 13 and the spring 15 of assemble case 16 inside.Left and right lifting controller 4 is packed in respectively on the left and right inwall of locker 1.Drive connecting rod 3 in each parallel rod and follower link 7 upper ends are hinged on the both sides of magazine 2 respectively.The lower end of follower link 7 is hinged on the bearing pin 8 at 2 times square casing 6 two ends of magazine.Install handle 5 by connecting axle 11 between the magazine 2 two bottom sides supporting legs, utilize handle 5 to rely on lifting controller 4 and parallel rods, can make magazine 2 between limes superiors position (shown in the double dot dash line among Fig. 2 in the solid box) and limit inferior position (among Fig. 2 shown in the double dot dash line of solid box front lower place), carry out lifting.On the sidewall of housing 16 relative connecting rods cambered

way

12 and 18 are set.The interstitial hole of drive connecting rod 3 lower ends is packed in central rotating shaft 10 ends that stretch out housing 16 sidewalls, hole is affixed with last active pin shaft 17 ends that stretch out housing cambered way 18 on it, hole is affixed with following active pin shaft 9 ends that stretch out housing cambered way 12 down for it, last active pin shaft 17 other ends are hinged on spring 15 lower ends that are arranged at housing 16 upper walls, following active pin shaft 9 other ends are hinged on the cylinder body lower end of damping buffer 13, and piston rod 14 upper ends in the cylinder body are hinged on the fixed axis 20 of housing 16.Protective baffle plate 19 is equipped with in housing 16 inside or outside at lifting controller 4, and protective baffle plate 19 is sleeved on the central rotating shaft 10, works to have prevented that foreign matter from entering in the housing 16 from cambered way 12 or 18.Cambered

way

12 or 8 on the housing 16 can guarantee that damping buffer 13 or spring 15 move by the running orbit of setting, and to produce desirable energy storage and buffering effect, make magazine 2 steady liftings.Cambered way 12 on the while housing 16 or 18 two ends, the location block body of upper and lower extreme position when also can be used as drive connecting rod 3 motions.For guaranteeing that this device steadily locatees in the lifting final position, the two ends in cambered

way

12 or 18 install soft cushion pad 21 additional.

During use, magazine 2 pulled out from locker 1 with handle 5.When magazine 2 moves downward, left and right parallel rod rotates to the front lower place, drive connecting rod 3 drives spring 15 and stretches, produce opposing torque and energy storage, while compression damping buffer 13, air flows out by throttle orifice, has played cushioning effect, thereby controlled the speed that magazine 2 descends, magazine 2 is steadily descended until the limit inferior position.Passive connecting rod 7 is connected with sleeve pipe 6, thereby guaranteed the synchronous rotation of two lifting controllers 4 and parallel linkage thereof.When magazine 2 recovery home positions move upward, drive connecting rod 3 drives spring 15 and resets, and discharges energy storage and stretching damping buffer 13 simultaneously, with the speed of control magazine 2 risings, magazine 2 is steadily risen until the limes superiors position, easily recover reset condition.
