The paulin socket of children trolley
Technical field
The utility model relates to a kind of paulin socket that is applied on the children trolley.
Background technology
In the paulin socket of the children trolley of prior art, the paulin socket is housed on the go-cart vehicle frame, the end of paulin socket and paulin inserted link is by the turning cylinder setting that rotates, between the end of paulin socket and paulin inserted link lockout mechanism is arranged, lockout mechanism comprises a plurality of perforates of being opened on the paulin socket, is located at a plurality of projections that are used on the paulin joint insert in the perforate, and a plurality of perforates, a plurality of projection are all spaced successively along the circumferencial direction that with the turning cylinder is the center.Be covered with the cloth cover on the many tarpaulin rods of go-cart vehicle frame, tarpaulin rod is supporting the cloth cover to play the effect of blocking, when needs use the cloth cover, rotate tarpaulin rod, the cloth cover is in tightens open state, utilize the relative position of lockout mechanism locking tarpaulin rod and paulin socket to get final product then, but, because lockout mechanism is to adopt cooperating of projection and perforate, and a plurality of projections or a plurality of perforate are spaced successively, this distance at interval makes that under many circumstances the cloth cover can not be tauted fully and open, and makes that the occlusion effect of cloth cover is bad.
Summary of the invention
The purpose of this utility model is to provide a kind of paulin socket of children trolley, and this structure can be tightened open state fully so that the cloth cover can be in.
In order to reach above purpose, the technical solution adopted in the utility model is: a kind of paulin socket of children trolley, comprise the paulin socket that is located on the go-cart vehicle frame with open mode and folded state, tarpaulin rod, it also comprises the paulin joint that rotates and be provided with by first turning cylinder and described paulin socket, be provided with the lockout mechanism that is used to lock both relative positions between described paulin joint and the described paulin socket, described paulin joint is provided with the elastic component that is used to provide the elastic-restoring force in described tarpaulin rod end by the setting that rotates of second turning cylinder and described tarpaulin rod end between described paulin joint and the described tarpaulin rod end.
Described lockout mechanism comprises a plurality of perforates of being opened on the described paulin socket, is located at the projection that is used on the described paulin joint insert in the described perforate, and a plurality of perforates are spaced successively along the circumferencial direction that with first turning cylinder is the center.
Described paulin joint is provided with a plurality of described projections, and a plurality of described projections are also spaced successively along the circumferencial direction that with first turning cylinder is the center.
Because the utility model has adopted above technical scheme, its advantage is: be provided with the paulin joint on the paulin socket rotationally, the paulin joint also with the setting that rotates of tarpaulin rod end, be provided with elastic component between paulin joint and the tarpaulin rod end, this elastic component is used to provide the tarpaulin rod end elastic-restoring force, when needs open the cloth cover, compression elastic piece at first, rotate the paulin joint then as far as possible and open the cloth cover, lock both relative positions by the lockout mechanism between paulin joint and the paulin socket again, simultaneously because elastic component is in deformed state, then under the elastic-restoring force effect of elastic component, the cloth cover can be tightened fully to be opened, and then the occlusion effect of cloth cover is good.

The specific embodiment
Further set forth concrete structure of the present utility model below in conjunction with accompanying drawing.
Shown in accompanying drawing 1-3, a kind of paulin socket of children trolley, be used for the supports cloth cover, it is by the paulin socket 2 that is located on the go-cart vehicle frame 1, tarpaulin rod 4, paulin joint 5 is formed, go-cart vehicle frame 1 has open mode and folded state, one end of paulin joint 5 rotates with paulin socket 2 by first turning cylinder 10 and is connected, be provided with lockout mechanism 7 between the end of this paulin joint 5 and the paulin socket 2, be used for when turning to correct position, locking its control position when paulin joint 5, the end of tarpaulin rod 4 has paulin plug 3, the other end of paulin joint 5 rotates with paulin plug 3 by second turning cylinder 11 and is connected, be provided with the elastic component 6 that is used to provide 3 one elastic-restoring forces of paulin plug between paulin joint 5 and the paulin plug 3, this elastic component 6 is a torsion spring, and its both ends are against respectively on paulin joint 5 and the paulin plug 3, as shown in Figure 3.
In the children trolley shown in the accompanying drawing 1, go-cart vehicle frame 1 is symmetrical, has left pulling handle rod 12, right pulling handle rod 13, left side pulling handle rod 12, be separately installed with paulin socket 2 on the right pulling handle rod 13, tarpaulin rod 4 is the U type, arch upward in top to go-cart vehicle frame 1, the connection mode of its both ends and paulin socket 2 is as described in the epimere, for supports cloth cover stably, tarpaulin rod 14 after also having one on the go-cart vehicle frame 1, the end of back tarpaulin rod 14 has back tarpaulin rod plug 16, this back tarpaulin rod plug 16 rotates with paulin socket 2 and is connected, has blocking device 15 between the two, paulin joint 5 and paulin socket 2 in the similar epimere of its connection mode and principle of work, when work, back tarpaulin rod 14 is positioned in left pulling handle rod 12, on the right pulling handle rod 13, as shown in Figure 1, after opening go-cart vehicle frame 1, in the time of need opening the cloth cover, buttress slightly compression elastic piece 6 of tarpaulin rod 4, rotate paulin joint 5 then as far as possible and open the cloth cover, lock both relative positions by the lockout mechanism 7 between paulin joint 5 and the paulin socket 2 again, unclamp tarpaulin rod 4 simultaneously, because elastic component 6 is in deformed state, then under the elastic-restoring force effect of elastic component 6, the cloth cover can be tightened fully to be opened, then the occlusion effect of cloth cover is good, and is tightened fully when opening at the cloth cover, and elastic component 6 still is in deformed state.When drawing the cloth cover in wanting Folding trolley vehicle frame 1, unlock lock mechanism 7, the paulin joint 5 that rotates backward gets final product.
In the present embodiment, lockout mechanism 7 comprises a plurality of perforates 8 of being opened on paulin socket 2 one sides, be located on the paulin joint 5 with paulin socket 2 opposite sides and be used to insert a plurality of projections 9 in the perforate 8, and a plurality of perforates 8, a plurality of projection 9 are spaced successively along the circumferencial direction that with first turning cylinder 10 is the center.Firmly rotate paulin joint 5, projection 9 is separated with perforate 8, and when turning to projection 9 and perforate 8 once more when relative, projection 9 inserts perforates 8 realizations and locks.
In accompanying drawing 2 and accompanying drawing 3, this back tarpaulin rod plug 16 and blocking device 15 between the paulin socket 2 also are by the circular hole that is located at paulin socket 2 opposite sides, are located at this back tarpaulin rod plug 16 and match with the protrusion of paulin socket 2 opposite sides and finish.
