Background technology
How present parallel moving door and the used door lifter of retractable door combine with a Daepori three-way motor and a worm reducer.Chinese patent discloses a kind of door lifter device (notice of authorization number: CN 1517508 A) of vertical hinged door, the body with runner that it comprises the lower lip that is installed on a body is provided with Worm and worm-wheel gearing in the transmission device in order to the running of driving runner that is provided with on the body; Be connected with in-line gears on the web; The door body is closed the ground that puts in place and is provided with the tooth bar that is meshed in order to gear, and tooth bar is provided with one and turns head, and the body of runner respective side portion is provided with a body and closes and can fasten the gib head that turns head when putting in place; Transmission device by motor, Worm and worm-wheel gearing and be connected in worm wheel shaft and the runner rotating shaft between sprocket wheel or gear drive form; Be provided with a taper body in the conical cavity of runner rotating shaft one end, the screwed hole that this taper body wore long in the middle part of a bolt and the runner rotating shaft in its duct, middle part links; The body of runner is installed in and is positioned on the location-plate of body lower lip, body is provided with the slide rail body that can slide up and down in the chute of location-plate, be provided with the extension spring assembly between slide rail body and the chute, the lower end of extension spring is connected on the following side of location-plate, the upper end is connected on the upper lateral part of body, and the extension spring upper end is adjusted on the upper lateral part of Bolt Connection at body through elastic force.But this door lifter is at closing time, because spreadet spreadet wheel and the tooth bar on ground on the wheel all are common profiles of tooth, and the easy dieback of tooth top at closing time, thus feasiblely knock at closing time, easily cause mechanical failure, even can not close the door.
The utility model content
The utility model technical issues that need to address provide a kind of dome profile of tooth spreadet spreadet wheel door lifter, it mainly is to solve the existing in prior technology door lifter at closing time, because the spreadet spreadet wheel on the wheel and the tooth bar on ground all are common profiles of tooth, the easy dieback of tooth top at closing time, thereby make and knock at closing time, easily cause mechanical failure, even the technical problem that can not close the door etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Dome profile of tooth spreadet spreadet wheel door lifter of the present utility model, comprise shell, be provided with body in the shell, body is connected with the support that can be installed together with door, it is characterized in that being connected with motor on the described shell, motor is connected with travelling gear, travelling gear connects and drives wheel, is coaxially connected with spreadet spreadet wheel on the wheel, and the tooth on the spreadet spreadet wheel is the dome profile of tooth, ground is provided with latch, latch be provided with can with the fixed gear or the tooth bar of spreadet spreadet wheel engagement.Support can be installed in a side of a body.Wheel can carry out under the driving of travelling gear clockwise or be rotated counterclockwise, and closes or opens thereby drive the door body.Tooth on the spreadet spreadet wheel and the tooth on the latch can all be the dome profile of tooth, like this when the door body is closed, the sound that spreadet spreadet wheel and fixed gear or tooth bar engagement are sent is less, and tooth top bumps against when avoiding taking place orthodont and closing the door engagement, damage frame for movement, even can not close situation about putting in place.Fixed gear is the part of the bigger gear of diameter, because fixed gear is circular arc, so spreadet spreadet wheel can enough on fixed gear climb reposefully, and the noise of generation is less.
As preferably, be provided with adjusting screw(rod) in the described body, the adjusting screw(rod) lower end is connected with spring base, and body is provided with the body chute that can allow support slide, and spring base is fixed with extension spring, and the extension spring lower end is connected on the support.Body can slide up and down in support by the chute of its bottom, and adjusting screw(rod) can be regulated the pressure of extension spring for ground, keeps the pressure of wheel to ground to adapt to the slope, ground.
As preferably, be connected with the locking hook of section on the body in the described shell for " 7 " font, latch is provided with can be by the fixed cantilever of locking hook hook.When the door body was closed, the locking hook can be hooked on the cantilever, prevents that door lifter is lifted in vertical direction.
As preferably, described travelling gear is intermeshing three.The travelling gear that is positioned at the top is connected with drive of motor, and the travelling gear of below is connected with wheel is coaxial, and the gear at middle part has played the effect of carrier gear.
Therefore, the profile of tooth that the utlity model has on the spreadet spreadet wheel is the dome profile of tooth, at door lifter at closing time, the fixed gear on spreadet spreadet wheel and ground or tooth bar engagement are comparatively steady, characteristics such as door body sound when operation is less, has avoided noise pollution, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering among the figure: shell 1, support 2, motor 3, travelling gear 4, wheel 5, spreadet spreadet wheel 6, latch 7, fixed gear 8, body 9, adjusting screw(rod) 10, body chute 11, extension spring 12, locking hook 13, door body 14.
