Any and all combinations of project.
The utility model relates to a kind of supporting mechanisms.For example, the supporting mechanism includes mounting rack, linkage unit and branch
Strut is provided with stopper protrusion on the mounting rack, and the linkage unit includes support tube and ejection rod.For example, the branch
Support cylinder is rotatably arranged on the mounting rack, and the ejection rod is actively set on the support tube and is locked to the branch
It supports in cylinder, one end of the support rod is rotationally connected in the stopper protrusion, and the other end is formed with support end.For example, described
Ejection rod is coupled on the support rod far from one end of the support tube, for driving the relatively described mounting rack of the support rod
Rotation is to realize support.
It please refers to Fig.1 to Fig.3, a kind of supporting mechanism 100, including mounting rack 20, linkage unit 30 and support rod 40, institute
It states and is provided with stopper protrusion 21 on mounting rack 20, the linkage unit 30 includes support tube 31 and ejection rod 33, the support
Cylinder 31 is rotatably arranged on the mounting rack 20, and the ejection rod 33 is actively set on the support tube 31 and is locked to
In the support tube 31, one end of the support rod 40 is rotationally connected in the stopper protrusion 21, and the other end is formed with support
End 41, the ejection rod 33 is coupled on the support rod 40 far from one end of the support tube 31, for driving the support
Bar 40 is rotated relative to the mounting rack 20 to realize support.
For example, the use process of the supporting mechanism 100 is specific as follows: by making the ejection rod 33 from the support tube
It is released in 31, the ejection rod 33 slides to extend relative to the support tube 31, and then supports the support rod 40
Rotation, enables the support rod 40 to extend and be supported to the mounting rack 20.
When the mounting rack 20 is installed on the head of back cushion, the ejection rod 33 can drive the support rod 40 to revolve
Turn and stretch, to be supported to the mounting rack 20, so that the head of seat can be realized stable support.And due to
The ejection rod 33 pop-up can be driven the mounting rack 20 and stretch so that the triggering use of the supporting mechanism 100 compared with
For convenience.
For example, being formed with sliding channel on the support rod 40 for the ease of limiting the rotation angle of the support rod 40
43, mounting blocks 431 are provided in the sliding channel 43, and the ejection rod 33 is rotationally connected on the mounting blocks 431.It is described
One end of sliding channel 43 is provided with limit body 433, and limiting slot 4331, the mounting rack 20 are provided in the limit body 433
Stopper protrusion 21 be convexly equipped in the limiting slot 4331.The limiting slot 4331 is fan groove, the cross of the stopper protrusion 21
Section is sector, is held on the side wall of the limiting slot 4331 to the side walls of the stopper protrusion 21.By will be described
Stopper protrusion 21 is convexly equipped in the limiting slot 4331, so that the stopper protrusion 21 can support the limiting slot 4331
Side wall, and then the rotation angle of the support rod 40 is limited using the installation part, to prevent the rotation of the support rod 40
Gyration is excessive and causes to be unable to stress, improves the support degree of the supporting mechanism 100.
For example, for the ease of make the ejection rod 33 convenient for pop-up, the ejection rod 33 far from the support rod 40 one
End is formed with sliding part 331, the first elastic component 35 is provided in the support tube 31, the end of first elastic component 35 supports
In on the sliding part 331.The ejection rod 33 is concavely provided with fastening groove 333, is additionally provided with stopper on the support tube 31
(not shown), the stopper are locked in the fastening groove 333, to engage the ejection rod 33.By stirring the locking
Part, so that the stopper is detached from the fastening groove 333 and discharges the ejection rod 33, the ejection rod 33 is in first bullet
Property part 35 elastic force under, can be slided relative to the support tube 31 and uphold and the support rod 40 be driven to rotate, so that institute
The triggering for stating ejecting mechanism is relatively easy to.
For example, for the ease of engaging the ejection rod 33, to prevent the arbitrarily pop-up of ejection rod 33, the support tube 31
In be additionally provided with the second elastic component (not shown), second elastic component is oppositely arranged with first elastic component 35, described
Two elastic components are sheathed on the ejection rod 33 and are held in the stopper.The stopper is rotatably arranged in the branch
It supports on cylinder 31, and the extending direction of the relatively described support tube 31 is obliquely installed.The center of the stopper and the support tube 31
The distance of axis is gradually increased along the direction far from first elastic component 35, i.e., stopper described in described second resilient element urges
Sloped-end be held in the fastening groove 333 of the ejection rod 33.Described is overcome when stirring the stopper using hand
The elastic force of two elastic components rotates, and when so that the stopper being detached from the fastening groove 333, first elastic component 35 can be driven
The ejection rod 33 is long.When enforcing the ejection rod 33 and the elastic force of first elastic component 35 being overcome to shrink, the bullet
The side wall of multiple fastening grooves 333 on rod 33 can push against the stopper and rotate and be detached from the fastening groove 333, so that institute
Stating ejection rod 33 can smoothly enter in the support tube 31, when the ejection rod 33 is shunk in place, the stopper card
Enter in a fastening groove 333 of the end of the ejection rod 33, to be caught in the ejection rod 33 to prevent the ejection rod
33 pop-up.By above-mentioned setting, the rotation and support of the support rod 40 can be realized only by the stopper is stirred,
So that the operation of the support construction is more convenient.
The utility model also provides a kind of seat 300.The seat 300 include cushion 50, back cushion 60 and as described above
Supporting mechanism 100, the back cushion 60 is rotatably arranged in the side of the cushion 50, and the mounting rack 20 is installed on described lean on
On pad 60.Support of the support rod 40 to the back cushion 60 can be realized by stirring the stopper, so that the seat
300 using more convenient.
Each technical characteristic of embodiment described above can be combined arbitrarily, for simplicity of description, not to above-mentioned reality
It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, all should be considered as described in this specification.
Embodiment described above only expresses the several embodiments of the utility model, and description is more specific and detailed
Carefully, but it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the general of this field
For logical technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these are all
Belong to the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
