Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
See Fig. 1 to Fig. 6, the folding release joint described in the utility model one preferred embodiment comprises shell 10, the substrate 20 be fixed in described shell 10, the lockout mechanism 50 that is articulated in the first driving chip 30 on described substrate 20 and the second driving chip 40 and is arranged on described substrate 20.Described first driving chip 30 is provided with the first rotating shaft 60, described first driving chip 30 offers the first axis hole 31 installing described first rotating shaft 60, described second driving chip 40 is provided with the second rotating shaft 70, described second driving chip 40 offers the second axis hole 41 installing described second rotating shaft 70, be connected with connecting strap 80 between described first rotating shaft 60 and the second rotating shaft 70, on described first driving chip 30 and the second driving chip 40 corresponding offer can be overlapping the first lock slots 32 and the second lock slots 42.Described lockout mechanism 50 is arranged on described substrate 20, and described lockout mechanism 50 can be inserted in described first lock slots 32 and the second lock slots 42 to realize folding release joint locking simultaneously.
Described first driving chip 30 is between the second driving chip 40 and substrate 20, and described substrate 20 is between the first driving chip 30 and connecting strap 80.Described substrate 20 offers the first waist hole 21 and the second waist hole 22, described first rotating shaft 60 and the second rotating shaft 70 are inserted into described first waist hole 21 and the second waist hole 22 respectively, and when folding release joint locking or when unlocking, described first rotating shaft 60 and the second rotating shaft 70 are simultaneously mobile in the first waist hole 21 and the second waist hole 22.Described first waist hole 21 and the second waist hole 22 are arcuate socket.The arcuate surface in described first waist hole 21 is towards the arcuate surface in the second waist hole 22.The side of described first driving chip 30 offers holding tank 33, and when described lockout mechanism 50 locks the first driving chip 30 and the second driving chip 40, described second rotating shaft 70 is held in described holding tank 33.For the ease of the first driving chip 30, second driving chip 40 is fixed with substrate 20 and prevents the first driving chip 30, second driving chip 40 rotates with substrate 20 and misplaces, this first driving chip 30, second driving chip 40 can realize pivot joint by a rotating shaft or pin respectively again with substrate 20, thus at the first driving chip 30, time second driving chip 40 opposing substrate 20 rotates, first driving chip 30, second driving chip 40 is with this rotating shaft or sell for axle center opposing substrate 20 rotates, and in the present embodiment, this first driving chip 30, second driving chip 40 fixes the first driving chip 30 with substrate 20 by housing, the position of the second driving chip 40 and substrate 20, to prevent the first driving chip 30, inconsistent phenomenon is there is when second driving chip 40 opposing substrate 20 rotates.
Described lockout mechanism 50 comprises and to be arranged on described substrate 20 and can the dead bolt bar 51 that moves up and down of relatively described substrate 20 and the actuated piece 52 that drives the relative described substrate 20 of described dead bolt bar 51 to move up and down.One end 511 of described dead bolt bar 51 is inserted in the first lock slots 32 and the second lock slots 42, and this end can called after lock head.Described actuated piece 52 comprises clamp hook piece 53, described dead bolt bar 51 is provided with buckle slot 54, described clamp hook piece 53 clasp is in described buckle slot 54, in the present embodiment, the height of described buckle slot 54 is greater than the height of clamp hook piece 53, be in the lock state in folding release joint or released state time, the interior hook face 531 of described clamp hook piece 53 supports buckle slot 54, certainly, in other embodiments, the size of this buckle slot 54 can just in time adaptive clamp hook piece 53.Described buckle slot 54 and described lock head 511 are oppositely arranged on the two ends of described dead bolt bar 51.Described substrate 20 is provided with the vertical position-limited trough 23 extended, described dead bolt bar 51 protrudes out the banking stop 55 being formed with and stretching in described position-limited trough 23, described banking stop 55 can move up and down in described position-limited trough 23, in the present embodiment, spring (not shown) is also provided with in described position-limited trough 23, described spring is positioned at the below of described banking stop 55, is clamped between described banking stop 55 and position-limited trough 23.
The principle of work in above-mentioned folding release joint is as follows: when folding release joint is in the lock state, the first lock slots 32 on described first driving chip 30 and the second driving chip 40 and the second lock slots 42 overlap, the end 511 (i.e. lock head) of dead bolt bar 51 is inserted in the first lock slots 32 and the second lock slots 42, the banking stop 55 of dead bolt bar 51 is positioned at the upper end of position-limited trough 23, and the interior hook face 531 of clamp hook piece 53 supports buckle slot 54, when this folding release joint needs to unlock, actuated piece 52 is first driven to move down, because in clamp hook piece 53, hook face 531 supports buckle slot 54, so, actuated piece 52 promotes dead bolt bar 51 and moves down, now, banking stop 55 acts on spring, make spring-compressed, the lock head 511 of dead bolt bar 51 shifts out in the first lock slots 32 and the second lock slots 42, realize unlocking, now, apply external force on the first driving chip 30 and the second driving chip 40, conter clockwise and clws rotate respectively under the driving of external force to make the first driving chip 30 and the second driving chip 40, when the first driving chip 30 and the second driving chip 40 rotate, first driving chip 30 and the second driving chip 40 drive the first rotating shaft 60 and the second rotating shaft 70 to move up in the first waist hole 21 and the second waist hole 22, to realize the folding of folding release joint, when needs will fold the expansion of release joint, external force drives the first driving chip 30 and the second driving chip 40 cw and rotating counterclockwise respectively, until the lower port that the first rotating shaft 60 and the second rotating shaft 70 move to the first waist hole 21 and the second waist hole 22 cannot move, now, first lock slots 32 and the second lock slots 42 overlap, promote actuated piece 52 again to move up, the interior hook face 531 of clamp hook piece 53 no longer supports buckle slot 54, dead bolt bar 51 under the action of the spring, move up and drive the lock head 511 of dead bolt bar 51 to be inserted into the first lock slots 32 and the second lock slots 42, to realize locking.
A kind of children trolley of the present utility model comprises above-mentioned folding release joint, the push handle (not shown) be fixed on described first driving chip 30, the front-wheel pole (not shown) be fixed on described second driving chip 40, be fixed on the rear wheel fulcrum bar (not shown) on described substrate 20 and be separately positioned on described front-wheel pole and show and the roller (not shown) on rear wheel fulcrum bar.
In sum, above-mentioned folded release joint compared with prior art, structure is simple, it by directly offering the first lock slots 32 and the second lock slots 42 on the first driving chip 30 and the second driving chip 40, then the first lock slots 32 and the second lock slots 42 is directly inserted into lock by dead bolt bar 51, directly promote it by actuated piece 52 has moved up and down the locking and unlocking to this dead bolt bar 51 again, thus convenient operation, and there will not be stuck phenomenon.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
