New description: [New technical field] This creation is a front wheel rotation positioning device for baby carriages, especially one that can set the orientation or free steering of the front wheel and can easily disassemble or assemble the front wheel. [Prior Art] The stroller is mainly composed of a frame and a plurality of wheels pivoted at the bottom of the frame. The 'frame will be covered with green woven cloth for the lion to sit, and the frame is equipped with a push handle. In order to allow the family to hold the handlebars, the frame can be pushed forward by the wheels; the currently visible baby carriages are distinguished by the frame structure, which can be divided into foldable and non-foldable seats. To distinguish, there are single seats and double seats, which are distinguished by function. There are general and sports types that are distinguished by wheels. 'There are two-wheel type and four-wheel type, etc., in the case of sports strollers (see US Pat. No. 6,196,572) Patent, No. 5, 876, No. 3, No. 9 and No. 5, 536, 〇 33 唬 patents. 'Sports baby strollers provide parents with a jog during the outing, allowing infants to ride in the car. Pushing the stroller together, usually the sports stroller is controlled. The convenience of the H series adopts the two-wheel design, that is, the front wheel is set to one, and the rear wheel is set to two. 'Because the user is in motion (ie, jogging) ), the speed at which the stroller is pushed It’s a bit faster, so it’s a danger of strolling in order to avoid road conditions or the user’s inadvertently causing a sudden sharp turn of the front wheels. The front and rear wheels are moving in the direction of the stroller and cannot turn. , _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ When the baby pushes the stroller, it is easy to accidentally touch the obstacle jamming mechanism, and the front wheel is not ready for the release of the extravagant. [New content] This is the case of '_ artificially solving the front wheel rotation positioning of the above-mentioned baby stroller and can be #=一: Γ 系 系 设置 设置 设置 轮 轮 轮 轮 轮 轮 轮 轮 轮 轮 轮 轮 轮 ' ' ' ' ' ' ' 第 第 第 第 第 第 第 第The position is to make the sugar group sway from the _ shape; to detach, to use the bribes to smash the assembly or disassemble the wheel set to achieve the effect of convenient operation. And the group of easy to create other purposes and advances apply The _ can be as detailed below. However, these detailed descriptions and the examples mentioned are for illustrative purposes only. Because of the spirit and scales of the creation of the book, the changes and corrections for this line of people are sufficient. It can be clearly seen from these detailed descriptions and drawings, but these detailed days and drawings are for illustrative purposes only, and should not be written by the ship. The description is as follows: [Embodiment] > The first embodiment of the stroller front wheel rotation positioning device shown in the second to the second embodiment is mainly disposed at the lower end of the footrest 1G of the stroller frame, thereby controlling the position of the wheel 3 and not being disassembled; the embodiment includes: One wheel seat 2, one wheel set 3, - fixed seat 4, one positioning rod 5 and one bullet In the embodiment, the wheel base 2 is connected to the lower end of the front foot bar 10. In the embodiment, the seat 2 is welded to the inner side of the lower end of the front leg 1 and the sleeve is perpendicular to the ground. The sleeve 2G has an accommodating space 2 for rotating the axle 31 of the wheel set 3 in the accommodating space M320516 . 21 , and the sleeve 2 设置 is disposed at a position relative to the front leg 1 且The sleeve 20 is disposed above the outer cover of the sleeve 2 to close the outer cover of the sleeve 2 to restrain the axle 31 from rotating. The wheel set 3 is pivotally connected to the wheel 30, in this embodiment. Before the wheel "U" type, the tube 32 is pivoted to the wheel 3 (), and the front wheel is overlaid on the wheel shaft 3, and the front end of the axle 31 is a tapered surface 311, so that the axle 3 is extended. 2 accommodating space 21' and pushing the positioning rod 7 by the tapered surface 311 "The appropriate position of the shaft is provided with a wrap around the wheel (4) & moving = the groove is provided with - positioning paste, in this In the embodiment, the positioning object is a dimple-like dance-like solid seat 4' which is connected to the outer side of the lower end of the front leg 1 (), and has a lower end of the disc 10 and a sleeve 20 · Perforated outer end 11, 22 respectively coaxial with the pin 4 - helical ramp 42. , perforation 41 'and in the fixed seat hole '^ turn 5, is the mine can be loaded with the threat fixed seat 4 and the forward 1G through hole in the U, 4 Bu positioning rod 5 one end is the free end, the tooth makes the card The engine 51 has entered the card lp51 via the through holes u, 41, 22, and the positioning portion 313 is slammed. The positioning rod 5 is in the other, and is in contact with the end surface 521 of the wheel (4) and the spiral bevel 42 of the fixing base 4. @52, the pull handle 52 wheel ^ is placed between the fixed turn 5 and the front domain 1G, thereby maintaining the right, , , :=. In the present embodiment, the elastic member 6 is one. By means of the above-mentioned members, the positioning lever 5 is in the normal state, and the first armrest (the -mrr cartridge portion 51 is located at the positioning portion (10) of the wheel (four)) is shown to limit the rotation of the axle 31. Wheel 6 M320516 Group 3 is directional. When the operator rotates the handle 52, when the end face of the handle & handle rotates the handle 52, the pusher 42 is pushed forward, and the tender lever 5 is retracted from the positioning portion 313 to be engaged with the rotating groove. (Second position: as shown in Fig. 4), so that the axle Μ is subjected to the _, 嶋 (four) erection (four) _ movement, 俾 to make 360 degrees of free steering. When the operator pulls the positioning rod 5 by the pull handle 52, the positioning rod $\_ is rotated by the groove 312 (third position: as shown in Fig. 5). At this time, the wheel (4) is not restricted by the clamp rod 5, and thus the sleeve 2 is removed. When the positioning rod 5 is located at the first position, it is necessary to directly pull the drying to the second position, so that the wheel set 3 can be directly disassembled for the convenience effect. 2 The above-mentioned 'this creation has excellent miscellaneousness, novelty and progressiveness, and it is in line with the application requirements of the application of the law.
