Summary of the invention
The purpose of this utility model is to regulate lockout mechanism existing problems for the chair angle of the prior art described in background technology, and provide a kind of use safety, the chair angle that operation is simple and reliable regulates lockout mechanism.
The technical scheme that can realize goal of the invention of the present utility model is as follows:
A kind of chair angle regulates lockout mechanism, it comprises mounting plate, swivel arm, toothed disc, tooth plate and tooth plate locking piece, described swivel arm is fixedly connected with toothed disc, the rotating shaft of toothed disc is fixedly connected with mounting plate, the bottom of toothed disc is provided with the tooth of certain central angle, tooth plate is provided with the tooth coordinated with the tooth of toothed disc, the top of tooth plate is provided with axis hole, position corresponding with this axis hole on mounting plate is provided with axle, tooth plate can rotate relative to axle, the bottom of tooth plate is provided with the fore shaft of opening upwards, tooth plate locking piece comprises rocking bar, rotating shaft and lock dog, rocking bar and lock dog are equipped with the axis hole coordinated with rotating shaft, rotating shaft and mounting plate normal-running fit, rotating rocker can drive rotating shaft and lock dog to rotate, make the fore shaft deciliter of lock dog and tooth plate, the rotating shaft of tooth plate locking piece is provided with reduction torsion spring, the rotating shaft of tooth plate is provided with the torsion spring promoting tooth plate and rotate.
During for the ease of rotating rocker, rotating shaft and lock dog can synchronous axial system, and the rotating shaft of described tooth plate locking piece is provided with breach, are also provided with corresponding breach in the axis hole of correspondingly rocking bar and lock dog.
Chair angle of the present utility model regulates lockout mechanism, simple to operation, only upwards need move rocking bar can unlock, and safe and reliable, in the locked state, lock dog and tooth plate lock firmly, cannot throw off, because be provided with torsion spring in the rotating shaft of tooth plate, so when lock dog is separated with the fore shaft of tooth plate, torsion spring can directly promote tooth plate and rotate, and the tooth of tooth plate is separated with the tooth of toothed disc, and user can the angle of free adjustment backrest.
Accompanying drawing explanation
Fig. 1 is the structural representation that chair angle of the present utility model regulates lockout mechanism;
In figure, 1 is mounting plate, and 2 is swivel arm, and 3 is toothed disc, and 4 is tooth plate, and 5 is fore shaft, and 6 is rocking bar, and 7 is rotating shaft, and 8 is lock dog, and 9 is expansion link, and 10 is middle support column, and 11 is table, and 12 is tea cup holder.
Detailed description of the invention
A kind of chair angle as shown in Figure 1 regulates lockout mechanism, it comprises mounting plate 1, swivel arm 2, toothed disc 3, tooth plate 4 and tooth plate locking piece, described swivel arm 2 is fixedly connected with toothed disc 3, the rotating shaft of toothed disc 3 is fixedly connected with mounting plate 1, the bottom of toothed disc 3 is provided with the tooth of certain central angle, tooth plate 4 is provided with the tooth coordinated with the tooth of toothed disc 3, the top of tooth plate 4 is provided with axis hole, position corresponding with this axis hole on mounting plate 1 is provided with axle, tooth plate 4 can rotate relative to axle, the bottom of tooth plate 4 is provided with the fore shaft 5 of opening upwards, tooth plate locking piece comprises rocking bar 6, rotating shaft 7 and lock dog 8, rocking bar 6 and lock dog 8 are equipped with the axis hole coordinated with rotating shaft 7, rotating shaft 7 and mounting plate 1 normal-running fit, rotating rocker 6 can drive rotating shaft 7 and lock dog 8 to rotate, make the fore shaft 5 deciliters of lock dog 8 and tooth plate 4, the rotating shaft 7 of tooth plate locking piece is provided with reduction torsion spring, the rotating shaft of tooth plate 4 is provided with the torsion spring promoting tooth plate 4 and rotate.
