Detailed ways

In order to further explain the technical solution of the utility model, the utility model is described in detail through specific examples below.

Referring to Fig. 1, a preferred embodiment of the utility model is used to adjust the fixing device 4 of the telescopic vehicle frame 3, which is composed of inner and outer vehicle frames 31, 32 which fit into each other; wherein, the inner The vehicle frame 31 is provided with a plurality of position-limiting parts 311 arranged at intervals; as for, the telescopic vehicle frame 3 can be applied to the rollator 2 or other related vehicles that need to be telescopically adjusted, and the figure of this embodiment is set on the rollator Telescopic frame 3 on the 2 is shown as an example.

With reference to Fig. 2 and Fig. 3, the fixing device 4 includes a fixing seat 41 which can be fixed on the outer frame 32, and a top catch which is arranged on the fixing seat 41 and can be extended into the limiting part 311. Device 42, a snap-fitting part 43 pivotally arranged on the fixed seat 41 and pushing against the top catcher 42, and a stop clasp 44 that can lock the snap-fit part 43 on the fixed seat 41; cooperate Referring to FIG. 4 , a slot 431 is provided on the engaging member 43 ; in addition, the stopper 44 has a locking member 441 pivotally arranged on the engaging member 43 , and a locking member 441 arranged on the fixing seat 41 . The fastened part 442, and an elastic part 443 arranged between the fastening part 441 and the engaging part 43. At the same time, in this embodiment, the locking portion 4411 can present a hook shape so as to be engaged with the fastened part 442; moreover, referring to FIG. 5 , in this embodiment , the ejector 42 has a ejector 421 that can be inserted into the limiting portion 311 by the engaging member 43, and a restoring member that is arranged between the fixing seat 41 and the ejector 421 422 , and the aforesaid top catch 421 is restricted in the fixing seat 41 by a baffle plate 423 locked on the fixing seat 41 .

Referring to Fig. 4 and Fig. 6, so when the length of the telescopic vehicle frame 3 is to be adjusted, one end of the locking member 441 must be pressed first, that is, the end of the locking member 441 as shown in the figure just corresponds to the elastic part 443, so that the locking part 4411 is out of the buckle of the fastening part 442, and the locking part 441 is continuously pressed down, so that the locking part 4411 is held by the fastening part 442 In the case of disengagement, refer to Fig. 5 and Fig. 7, and move the engaging member 43 in a direction opposite to that of the fixed seat 41, so as to impel the ejector 421 to disengage from the ejector of the engaging member 43, and simultaneously the return member 422 Due to its own restoring force, the ejector 421 can be pushed to move in the direction opposite to the limit portion 311, so that the ejector 421 leaves the limit portion 311, and the inner frame 31 is separated from the fixation of the fixed seat 41. , so that the inner frame 31 is telescopic on the outer frame 32 until it is adjusted to the required length; referring to FIG. The seat 41 moves in the direction, so that the engaging part 43 pushes against the top catch 421, and the top catch 421 goes deep into the limit part 311, and then the inner frame 31 and the fixed seat 41 are in a fixed state again. , refer to FIG. 9 , at the same time, when the engaging part 43 moves toward the fixed seat 41, the locking part 441 will be pushed under the elastic force of the elastic part 443, so that the locking part 4411 automatically aligns with the fixing seat 41. The buckle 442 is buckled and fixed, and then the buckle 43 is locked; therefore, when the utility model works, it must first maintain the action of pressing the lock 441, and then perform the operation of pulling the buckle 43 apart In order to make the locking part 4411 disengage from the fastening of the fastened part 442, the fastening part 43 can be opened, and then the length of the telescopic frame 3 can be adjusted, and at the same time, it is also possible to avoid individual accidental touches and misoperations. When the engaging member 43 is closed, the engaging member 43 will be pushed apart by itself, and then the telescopic frame 3 will not slide automatically, which effectively improves the safety of use.

To sum up the foregoing, the utility model is used to adjust the fixing device of the telescopic vehicle frame. By virtue of the design of the engaging piece and the stop fastener, when the engaging piece moves closer to the fixing seat, the engaging piece can be removed. Push the ejector to fix the outside of the telescopic frame, and at the same time, the locking part on the engaging part will be pushed back by the elastic part at the same time, so that the locking part is buckled on the buckled part , so that the locking part will be in a locked state, and when you want to adjust the telescopic frame later, that is, before you want to open the locking part, you must first keep pressing the locking part so that the locking part is separated from the locked part. Only when the fastener is connected, the fastener can be opened to make it open and disengaged. This will prevent the accidental touch and movement of the fastener, which will cause the lack of self-sliding of the telescopic frame, and effectively improve the use security.

The above-mentioned embodiments and accompanying drawings do not limit the product form and style of the present utility model, and any appropriate changes or modifications made by those skilled in the art should be regarded as not departing from the patent scope of the present utility model.
