Abstract
The utility model discloses a locking device for a plastic-steel composite skeleton seat armrest, which comprises a plastic skeleton, a steel internal skeleton, a mounting upright post, a positioning plate, a bolt clamping plate, a rotating shaft, a stop pin and a stretched spring, and is characterized by also having a non-slotted bolt, wherein the non-slotted bolt is rotationally connected with the positioning plate through a pin shaft; the clamping teeth on the front end of the non-slotted bolt is meshed with a plurality of clamping teeth on the bolt clamping plate; and the rear end of the non-slotted bolt is connected with the positioning plate through the stretched spring. The device has the advantages that: the position of the mounting upright post used for fixing the steel internal skeleton is changed; the non-slotted bolt is used, so the strength of the front end of the non-slotted bolt is improved greatly; the thickness of the non-slotted bolt is increased, so the clamping between the non-slotted bolt and the bolt clamping plate is more reliable; the range of a locking angle is enlarged; the strength of the bolt is increased; it is convenient to mount the locking device; and the entire locking device can be used safely and reliably.
Description
Technical field
The utility model relates to the passenger transport armchair equipment technical field, specifically is the locking device of the compound framework seat armrest of seat of a kind of plastic-steel.
Background technology
The existing compound framework seat armrest of seat of plastic-steel (ZL2006200967542) is replaced the figuration effect of virgin metal steel plate frame by plastic skeleton, and small-sized single-blade shape steel inner frame is installed in plastic skeleton is born support force, both guaranteed the intensity of armrest, steel have been saved again, weight reduction, but also be convenient to processing.Locking device in this armrest is made up of location-plate, dead bolt, dead bolt clamp, back-moving spring, dead bolt and location-plate are rotationally connected by bearing pin, the latch of dead bolt front end engages with a plurality of latches on the dead bolt clamp, is welded with rotating shaft on the dead bolt clamp and is rotationally connected by rotating shaft and steel inner frame front end.The position restriction that is subjected to the steel inner frame that column is installed owing to the dead bolt front end leaves the groove that can contact with the installation column, so just exists the locking angular range of retaining mechanism to lock defective not in place and dead bolt front end insufficient strength not quite, sometimes.
Summary of the invention
The purpose of this utility model provides and a kind ofly locks that angular range is big, the locking device of dead bolt intensity height, the compound framework seat armrest of seat of plastic-steel being convenient to install.
The locking device of the compound framework seat armrest of seat of described plastic-steel, comprise plastic skeleton, steel inner frame, column, location-plate, dead bolt clamp, rotating shaft, backing pin, back-moving spring are installed, it is characterized in that: locking device also is provided with no groove dead bolt, described no groove dead bolt is rotationally connected by bearing pin and location-plate, the latch of no groove dead bolt front end engages with a plurality of latches on the dead bolt clamp, and its rear end is connected with location-plate by back-moving spring.The thickness of described no groove dead bolt is greater than the thickness of dead bolt clamp.
The beneficial effects of the utility model are: the position that has changed the installation column that is used for fixing the steel inner frame, adopt no groove dead bolt, the intensity of no groove dead bolt front end is greatly improved, increased the thickness of no groove dead bolt again, it is more reliable that it is engaged with the dead bolt clamp, not only locks angular range and increase dead bolt intensity height, also be convenient to install, its integral locking device is safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: the 1-polyurethane foam layer, the 2-plastic skeleton, 3-steel inner frame, the 4-rotating shaft, the 5-backing pin, 6-installs column, and 7-does not have the groove dead bolt, 8-location-plate, 9-back-moving spring, 10-dead bolt clamp.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, among Fig. 1, the locking device of the compound framework seat armrest of seat of described plastic-steel, comprise plastic skeleton 2, steel inner frame 3, column 6, location-plate 8, dead bolt clamp 10, rotating shaft 4, backing pin 5, back-moving spring 9 are installed, it is characterized in that: locking device also is provided with no groove dead bolt 7, described no groove dead bolt 7 is rotationally connected by bearing pin and location-plate 8, the latch of no groove dead bolt front end engages with a plurality of latches of dead bolt clamp 10, and its rear end is connected with location-plate 8 by back-moving spring 9.The thickness of described no groove dead bolt is greater than the thickness of dead bolt clamp.
No groove dead bolt front end there is no the installation column, and its activity point of view scope increases, and intensity increases, the locking device reliable operation.
