In the prior art, the expansion link mechanism that adopts on the perambulator generally include first rod member, with second rod member that first rod member slides mutually and is provided with, have the tube chamber and the fluting that extend along its length direction on second rod member, fluting and tube chamber are connected.The intensity that comprises first rod member rise subjective role the first rod member body, be arranged on locating part on the first rod member body, be connected the neck that is connected between the first rod member body and the locating part, locating part is inserted in the tube chamber, connect neck and be positioned at fluting, and the first rod member main body is positioned at outside the tube chamber, cloth cover can be installed on the first rod member main body or rotate and be connected etc. with other rod member, such expansion link mechanism is visually heavy, influences attractive in appearance; In addition, the expansion link mechanism of this structure only can carry out the shortening or the elongation of the length of rod member, but can not drive the 3rd parts that are arranged on second rod member and follow action.
Summary of the invention
Technical problem to be solved in the utility model provides the expansion link mechanism of using on a kind of new perambulator, and it is simple in structure and can drive other parts disposed thereon follow action when flexible.
For solving above technical matters, the utility model is taked following technical scheme:
The expansion link mechanism of using on a kind of perambulator, it comprises first rod member, second rod member that one end is plugged in the tube chamber of first rod member and can be provided with slidably along the length bearing of trend of first rod member and be used for lockout mechanism with the relative locking of first rod member with second rod member, be set with the slip backing member on the end that is positioned at first rod member of described second rod member, offer first position-limited trough that extends along the length direction of first rod member on the slip backing member, offer second position-limited trough that extends along its length direction on first rod member, described expansion link mechanism also comprises the sliding pin that passes second position-limited trough and stretch into first position-limited trough, other parts on this sliding pin and the perambulator are fixedly connected or one-body molded setting, when expansion link mechanism was in the lock state, sliding pin was sandwiched between the groove end face of the groove end face of first position-limited trough and second position-limited trough.
According to a concrete aspect of the present utility model, described lockout mechanism comprises the locked groove that is opened on the first rod member inwall, is slidingly arranged in the lock pin on the slip backing member and is used to make lock pin to be tending towards remaining on elastic component stage clip for example in the locked groove along the length direction perpendicular to first rod member, when lockout mechanism was in the lock state, lock pin was positioned at locked groove.In addition, be connected with an end of release drag-line on lock pin, the other end of this release drag-line is connected with operating knob on the other end that is arranged on second rod member.
Because the enforcement of above technical scheme, the utility model compared with prior art has following advantage:
The utility model is after the lockout mechanism release, second rod member can slip in first rod member, and after relative first rod member of second rod member had slided the stroke of length of first position-limited trough, it can drive sliding pin and follow action with other parts of sliding pin bonded assembly.In addition, the utility model is simple in structure.

The specific embodiment
Implement later-model expansion link mechanism according to this and can be implemented in elongating or shortening in the process of bar, other parts of perambulator disposed thereon also can be followed action, and this is very beneficial for simplifying the folding operation of folding baby carrier.With the be applied as example of the utility model at children trolley, the utility model is described in more detail below.
As shown in Figure 1, comprise that according to the expansion link mechanism of present embodiment first rod member 1, an end are plugged in intraluminal second rod member 2 in first rod member 1, are fixedly installed on slip backing member 3, the sliding pin 4 on second rod member, 2 bottoms and are used for the lockout mechanism of first rod member 1 with the 2 relative lockings of second rod member.
Offer first position-limited trough 30 that extends along its length direction on the slip backing member 3, offer second position-limited trough 10 that extends along its length direction on first rod member 1, sliding pin 4 passes second position-limited trough 10 and stretches in first position-limited trough 30, as shown in Figure 2, when lockout mechanism was in the lock state, sliding pin 4 was sandwiched between the last groove end face of the following groove end face of first position-limited trough 30 and second position-limited trough 10.
In this example, lockout mechanism comprises the locked groove 5 that is opened on first rod member, 1 inwall, is slidingly arranged in the lock pin 6 on the slip backing member 3 and is used for making lock pin 6 to be tending towards remaining on elastic component 7 (this example is stage clip) in the locked groove 5 along the length direction perpendicular to first rod member 1, when lockout mechanism was in the lock state, lock pin 6 was positioned at locked groove 5.In addition, be connected with an end of release drag-line 8 on lock pin 6, the other end of this release drag-line 8 is connected with operating knob 9 on the other end that is arranged on second rod member 2.
In this example, first rod member 1 is as the front frame of go-cart, and second rod member 2 is as the handle of go-cart, and is fixed with the adapter sleeve 11 that is used to connect sleeping basket, seat pocket 13 or automotive seats on the sliding pin 4, and the after poppet 12 of perambulator rotates with adapter sleeve 11 and is connected.
Comparison diagram 2 to 4 as seen, adopt the children trolley of present embodiment very brief from visually seeing, expansion link mechanism makes that the folding operation of go-cart is very simple, as long as operating operation is turned round 9 and is made the lockout mechanism release, second rod member 2 will glide then, when sliding pin 4 contacts with the last groove end face of first position-limited trough 30, the continuation of second rod member 2 is glided and can be driven sliding pin 4 and glide, thus driven other parts that are connected with sliding pin 4 comprise install adapter sleeve 11, after poppet 12 and with foldings such as adapter sleeve 11 bonded assembly sleeping baskets or seat pocket 13 or automotive seats.
More than the utility model has been done detailed description; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to spirit of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model.
