Description
Technical field
The utility model relates to the aluminum casting on garage door, especially a kind of leveling style garage door spring chuck.
Background technique
Garage door is that enterprise commonly uses facility, is applicable to public place or the houses such as the business shop front, garage, market, hospital, industrial enterprise, and especially door opening is comparatively large, and convenient, fast unlatching effect is played in the place of inconvenient installation ground door body.Garage door is generally divided into manual garage door and automatic garage door, due to manual garage door open and close trouble, and easily bad, all use automatic garage door at present.
Using more in automatic garage door is turnover panel garage door, because the built-in torsion spring of turnover panel garage door, torsion is suitable with door weight, and make a body be in " null gravity " state, and run by pulley in orbit, therefore resistance is little, power consumption is few, and maintenance rate is low, durable in use.One is reversed axostylus axostyle and is provided with two sections of torsion springs linked together, and the two ends of one section of torsion spring are separately installed with fixed spring chuck and rotary type spring chuck.In actual use, be that use two asymmetric bolts carry out being fixed on by spring chuck on torsion axostylus axostyle.Chinese patent CN 202833801 U discloses a kind of garage door spring chuck, and it is that spring chuck is fixed on torsion axostylus axostyle by the bolt hole 6 being 90 degree by angle.It is also that spring chuck is fixed on torsion axostylus axostyle by the bolt hole 8 being 90 degree by angle that Chinese patent CN 202900015 U discloses the flat wheel of garage door.This fixed form, the spring chuck reversing axostylus axostyle two ends can be made not easily to adjust, and coaxality is lower, in Long-Time Service process, the degree of wear is high, and working life is short.
Model utility content
The technical problems to be solved in the utility model is: in order to the spring chuck solving existing torsion axostylus axostyle two ends not easily adjusts, and coaxality is lower, in Long-Time Service process, the degree of wear is high, the problem that working life is short, the utility model provides a kind of leveling style garage door spring chuck, by being evenly equipped with at least three fixed vias for fixing spring dop at mounting head sidewall, the spring chuck reversing axostylus axostyle two ends can be adjusted when mounted easily, make it have higher coaxality, its wearing and tearing in use can be reduced, improve its working life.
The utility model solves the technological scheme that its technical problem adopts: a kind of leveling style garage door spring chuck, comprise integrated mounting head and installation shaft, described mounting head and installation shaft center are provided with the installation through hole for mounting spring dop, described mounting head sidewall is evenly equipped with at least three fixed vias for fixing spring dop, be provided with internal thread in described fixed via, the excircle of described installation shaft is provided with the thread groove mated with spring.
Conveniently mounting spring dop, is at least provided with a cylindrical hole below described each fixed via.
Particularly, two cylindrical holes are provided with below described each fixed via.
As preferably, described mounting head sidewall is evenly equipped with three fixed vias for fixing spring dop.
The beneficial effects of the utility model are: a kind of leveling style garage door spring chuck that the utility model provides, by being evenly equipped with at least three fixed vias for fixing spring dop at mounting head sidewall, the spring chuck reversing axostylus axostyle two ends can be adjusted when mounted easily, make it have higher coaxality, its wearing and tearing in use can be reduced, improve its working life; Such spring chuck uses more steadily, firmly, Safety performance is higher.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the schematic perspective view of a kind of leveling style garage door spring chuck of the present utility model.
In figure: 1. mounting head, 2. installation shaft, 3. through hole, 4. fixed via, 5. thread groove, 6. cylindrical hole are installed.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of leveling style garage door spring chuck, comprise integrated mounting head 1 and installation shaft 2, mounting head 1 and installation shaft 2 center are provided with the installation through hole 3 for mounting spring dop, mounting head 1 sidewall is evenly equipped with three fixed vias 4 for fixing spring dop, be provided with internal thread in fixed via 4, be provided with two cylindrical holes 6 below each fixed via 4, the excircle of installation shaft 2 is provided with the thread groove 5 mated with spring.
During installation, first bolt is screwed in advance in fixed via 4, axostylus axostyle will be reversed again through installing through hole 3, adjust the distance between spring chuck, finally select bolt, spring chuck is fixed on and reverses on axostylus axostyle, adjusted the coaxality of spring chuck by the bolt on adjustment spring chuck, make it have higher coaxality.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
