Abstract
The utility model provides a push rod strut rail locking mechanism of a trolley, comprising a push rod and a push rod strut rail. The inner side of the push rod is provided with a coupling component and a guide frame, and a slide block is arranged on the guide frame; a spring for the guide frame is arranged between the guide frame and the push rod, a locking head is arranged at the connecting point connected with the push rod on the push rod strut rail, and the upper side of the slide block is provided with a notch and a locking contact face. Two working conditions are provided between the locking head and the slide block, comprising a locking condition and an unlocking condition; under the locking condition, the locking head is conflicted with the locking contact face; under the unlocking condition, the locking head is disengaged from the locking contact face and is aligned with the notch. When the trolley being folded, the locking head and the slide block can be unlocked automatically, and the locking head can be inserted into the notch, decreasing the packaging volume.
Description
Technical field
The utility model relates to the lockout mechanism of the push rod stull of a kind of doll carriage, particularly go-cart.
Background technology
In the prior art, between the corresponding push rod of go-cart, the push rod stull is set usually, and in order to reduce the packaging volume of go-cart, the push rod stull is set to folding rod member.And during the Folding trolley vehicle frame, push rod stull and push rod must be able to relatively rotate, and also will guarantee the rigidity of vehicle frame simultaneously, and people are provided with an armrest usually and move the lockout mechanism of controlling between push rod stull and push rod, use very loaded down with trivial details.
Summary of the invention
The utility model purpose provides a kind of go-cart push rod stull lockout mechanism, and it can automatically lock and release when opening vehicle frame and folding stand, the trouble when reducing to use.
For achieving the above object, the technical solution adopted in the utility model is: a kind of go-cart push rod stull lockout mechanism, comprise the push rod that is arranged on the vehicle frame, the folding push rod stull that is connected rotationally with described push rod, be provided with the moving part that is connected with vehicle frame in the described push rod, and the saddle that is connected with described moving part, be provided with slide block on the described saddle slidably, be provided with the saddle spring between described saddle and the described push rod, be provided with elongated insertion part in the junction with described push rod in the described push rod stull, described slide block is provided with breach and locking contact surface; Two mode of operations are arranged between described elongated insertion part and the slide block, i.e. lock-out state and released state, under lock-out state, described elongated insertion part and described locking contact surface are inconsistent; Under released state, described elongated insertion part breaks away from described locking contact surface, and elongated insertion part is aimed at described breach.
Because technique scheme utilization, the utility model compared with prior art has following advantage: the release between elongated insertion part and the slide block can be finished automatically with locking, makes to open or need not operation bidirectional during folding stand, has brought convenience to use.

The specific embodiment
Referring to each accompanying drawing, a kind of go-cart push rod stull lockout mechanism, comprise the push rod 1 that is arranged on the vehicle frame, with the push rod stull 6 that described push rod 1 is connected rotationally, in the described push rod stull 6 stull turning cylinder 5 is set.Be provided with moving part 9 that is connected with vehicle frame and the saddle 3 that is connected with described moving part 9 in the described push rod 1, be provided with slide block 2 slidably on the described saddle 3, be provided with saddle spring 4 between described saddle 3 and the described push rod 1, be provided with sliding block spring 10 between described saddle 3 and the described slide block 2.Be provided with elongated insertion part 7 in the junction with described push rod 1 in the described push rod stull 6, described slide block 2 is provided with breach 11 and locking contact surface 8.Two mode of operations, i.e. lock-out state and released state are arranged between described elongated insertion part 7 and the slide block 2: under lock-out state, described elongated insertion part 7 and described locking contact surface 8 inconsistent (referring to accompanying drawing 1); Under released state, described elongated insertion part 7 breaks away from described locking contact surface 8, and elongated insertion part 7 is aimed at described breach 11 (referring to accompanying drawing 3).
Referring to accompanying drawing 1, accompanying drawing 2, be in the normal operating condition of opening in go-cart, moving part 9 is subjected to the spring force of making every effort to overcome clothes saddle spring 4 that inwardly pushes away of vehicle frame, make slide block 2 be in the position shown in the accompanying drawing 1, elongated insertion part 7 is in the lock state between the two with slide block 2 inconsistent making, locking contact surface 8 on elongated insertion part 7 and the slide block 2 is inconsistent and can't rotate, thereby can't fold push rod stull 6, and go-cart keeps rigidity preferably under open mode.Referring to accompanying drawing 3, during Folding trolley, at first be that moving part 9 suffered inside thrusts disappear automatically, saddle 3 drives slide block 2 and moves right under the effect of the spring force of saddle spring 4 then, elongated insertion part 7 just breaks away from described locking contact surface 8, elongated insertion part 7 and slide block release.Referring to accompanying drawing 4, accompanying drawing 5, after elongated insertion part 7 and slide block 2 releases, folding push rod stull 6, elongated insertion part 7 promptly inserts in the breach 11.And when launching go-cart once more, moving part 9 makes saddle 3 be in the state shown in the accompanying drawing 2 earlier, and slide block 2 is because the obstruction of elongated insertion part 7 and can't enter lock-out state; Spur push rod stull 6 again, elongated insertion part 7 rotates; When go-cart launched fully, elongated insertion part 7 went to the position shown in the accompanying drawing 3, and slide block 2 moves to the position shown in the accompanying drawing 1 rapidly under the spring force effect, and the locking of slide block 2 and locking block 7 promptly realizes.Slide block 2 is finished fully automatically with the locking and the releasing process of locking block 7, need not add any operation, and is convenient, laborsaving.
