New Description: [New type of technical and technical field] This creation is about the adjustment structure of a bicycle backrest frame, especially the adjustment structure of the backrest frame that is easy to assemble on the locomotive seat cushion. [Previous Technical Street] According to the 'current locomotive has been a very wide range of vehicles, and the rider can also ride passengers together, and the rain 5 often sets up a rear frame at the end of the rear seat. This rear frame not only provides cargo. For the purpose of using the passengers in the rear seat, it is more convenient for the passengers to use the help. However, not only does the passenger feel very uncomfortable when riding in the back seat, but it is more prone to danger; therefore, the follow-up industry design Although a fixed backrest s can solve the above problems, the fixed design also limits the gold pad space of the locomotive. When the rear seat has no passengers, the fixed backrest is also useless. The reason is that the lack of the structure of the former shackles is necessary for further improvement. In view of the current structure of the syllabus, the creators have made many years of experience in the production and marketing of the products, and they have made many improvements and tests on the existing methods of gull. After 'finally created lij a kind of adjustment structure of the backrest frame. [New content] Therefore, the main purpose of this creation is to provide an adjustment structure of a car body back frame with simple structure and convenient assembly. Another object of the present invention is to provide an adjustment structure that is convenient and effortless for adjusting the operation cover of the M293199. A further object of the present invention is to provide an adjustment structure for a rudder backrest having a safety of scales. In order to achieve the above object, the present invention proposes an adjustment structure of a vehicle body back frame, which is mainly provided with a backrest frame on a seat cushion of the vehicle body, and an adjustment structure is arranged between the backrest frame and the seat cushion, the adjustment structure It is composed of two sliding handles, two or more lock diagrams and more than one card block; _ the two slide rails are respectively locked relative to the two side edges of the seat cushion, and the bottom of each slide靣There are a plurality of positioning holes arranged in a plurality of cymbals, and each sliding _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ More than one screw hole, each screw hole is respectively provided for each lock screw to make the end portions of each lock country member reach the inner side of each slide rail, and when each card block is subjected to a pressing external force, each card The blocking posts of the block are respectively engaged in the positioning holes. Wherein, the locking end portions of the locking member respectively have a large diameter portion, and the large diameter portion is disposed to abut against the outer side of the sliding rail & wherein the clamping block is integrated with the backrest frame The backrest frame is covered with an outer cover plate ◎ wherein the two sliding sections are c-shaped. The following is a further explanation of the creation of the creation and the implementation of the drawings. In order to enable those who are familiar with the creation of the technology, the implementation of this specification. [Embodiment] M293199 First of all, please cooperate with the first to sixth figures of the reference circle. This creation is an adjustment structure of the car body back frame, which is mainly provided with a back frame 2 on the seat 塾1〇 of the rut. G, the back frame 20 and the seat cushion 1 are disposed with an adjustment structure 3 (as shown in FIG. / Figure), the adjustment structure 30 is composed of two slips 31, two or more locks - 3 2 and Two or more card blocks 33 (as shown in the third figure); the two sliding 31 series branches are locked relative to the lock country on the side edge of the seat cushion, and the bottom surfaces of each slide 3 1 are respectively set There are a plurality of positioning holes 3 1 1 in the form of a series of broadcasts, and each of the sliding blocks 3 1 is respectively accommodated by each of the card blocks 3 3 , and each of the cards is made up of 3 3 = the bottom part is assigned - New 3 3 i Drinking the 3 3 side of each card ship minus one or more 3 2 3 pieces of the end of the 3 2 can be abutted to the inner side of each slide 3 1 , when each cassette 3 3 is received by the positioning hole 3 11 (as shown in the sixth figure) Shown). Among them, the locker of the locker 3 2 has a large diameter part 3 2 1, and the large diameter part 3 2 1 is able to be in the heart of the miscellaneous 3 1 , the card block 3 3 £4舆The backrest frame 20—鳢former I The backrest frame 2 is covered with an outer cover panel 40. And from the combination of the above, please continue to match the first to sixth figures of the reference, * Ride the county locomotive and take the county office, the passengers _ get _ turn back frame 2 〇 ^ (four) α, secret There is a health (as shown in the first); and when the rear seat has no passengers and only a single rider, the rider can move to the predetermined position of the Zhengzhou rider on the backrest 2 〇 slide M293199, which only needs Slightly loosen the locks and lock the country pieces 32. When the backrest frame 20 is slid to the predetermined position, the shackle parts 3 2 can be tightened and the top side of the slippery 3 1 can be easily closed. The position adjustment of the backrest frame 20 is completed, and the overall adjustment mode is convenient; the face rider rides in an emergency situation and the back of the country rider is back, so that the back frame 20 will be backward. The German pressure, the face of each card rhyme block 3.3 is under the pressure of Ling Li, at this time, each card block, 3 3 block 枉 3 3 1 is able to agree to the positioning hole 3 of each slider 3 1 In 1 1 , the rain does not slip backwards (as shown in the sixth figure), so that because the back frame 20 can be tightly coupled with the rider 5, not only can the team stop after the car chase, in the first Provides safety protection and prevents salty injuries from being carried out by the rider's body. Further, the safety of the vehicle body is provided. f In summary, the adjustment structure of the body frame of the present invention effectively improves the conventional structure. There are various shortcomings, and the main technical means of this creation have not been found in any of Yan Yan's publications. γ Cheng is in compliance with the application requirements of the new patent, and is requested to apply in accordance with the law.
