Description

【Technical Field】 【0001】 The present invention relates to the field of leisure sports goods, and more specifically to golf bags. 【Background Art】 【0002】 At the top of golf bags, external frames are provided for people to easily lift the bags. Handles are provided on the external frames, and the entire bag is pulled by the handles. Due to many elements in the external environment, when carrying a golf bag, there is a certain inevitable sway, and different degrees of collisions occur to the golf bag. Currently, the external frame of the golf bag and its handle are locked to each other. When carrying the golf bag, there is no buffer space on the handle. Therefore, during the pulling process, the bag is likely to be impacted by a large shock, and the bag wears and gets damaged, which is inconvenient for people and has low practicality. 【0003】 In order to solve the above technical problems, the patent document with the authorization announcement number CN211935458U discloses a collision prevention frame structure for a golf bag including a head frame and a hand-held part. On both sides of the head frame, symmetric first mounting parts and second mounting parts are respectively provided. Mounting holes are provided in both the first mounting part and the second mounting part. Connection blocks that fit with the mounting holes are respectively provided at both ends of the hand-held part. Slide grooves are provided in the connection blocks. The hand-held part is slidably locked into the mounting holes of the first mounting part and the second mounting part respectively through the connection blocks. Retaining screws inserted into the slide grooves are provided in both the first mounting part and the second mounting part. By designing the handle fixed to the conventional external frame as a telescopic structure, the patent document has a buffer space between the external frame and the hand-held part, effectively avoiding collisions during the pulling process and reducing the collision impact force of the golf bag, thereby achieving the protection effect of the bag. 【0004】 In the above-mentioned patent document, the retaining screw can be displaced along the slide groove, and when subjected to impact during the pulling process, the handle can retract into the outer frame. Thus, the handle has only two restraining positions relative to the outer frame: one is when the retaining screw is at one end of the slide groove and the handle extends outward, and the other is when the retaining screw is at the other end of the slide groove and the handle is retracted. [Overview of the Initiative] [Problems that the invention aims to solve] 【0005】 The technical problem that this invention aims to solve is how to fix the handle portion in multiple positions relative to the head frame body, allowing the user to easily adjust the position of the handle portion themselves. [Means for solving the problem] 【0006】 To solve the above technical problems, the present invention provides the following technical means. The handle-extendable head frame includes a head frame body and a handle, a female connector structure is fixed to the side wall of the head frame body, the handle is U-shaped, a male connector structure is provided at the end of the handle, an elongated groove is formed in the male connector structure, a fastening hole is provided in the female connector structure, a fastening bolt is fitted into the fastening hole, the fastening bolt is located in the elongated groove, a plurality of position-restricting locking grooves are provided in the male connector structure, the plurality of position-restricting locking grooves are distributed along the length direction of the male connector structure, and an elastic sheet is provided in the female connector structure that can engage with any of the position-restricting locking grooves. 【0007】 When the user pulls the handle out or retracts it relative to the head frame body, the male connector structure is displaced relative to the female connector structure. Depending on the amount of displacement of the male connector structure relative to the female connector structure, the elastic sheet moves beyond a predetermined number of position-limiting locking grooves and finally engages with the position-limiting locking grooves, initially positioning the handle on the head frame body. Subsequently, the user tightens the fastening bolts, which fasten the female connector structure to the male connector structure, fixing the position of the handle on the head frame body. 【0008】 Both the female connector structure and the male connector structure are hollow and flat. When the user tightens the fastening bolt, the flat structural design is advantageous because it allows the female connector structure and the male connector structure to make contact over a wide area. Furthermore, the hollow male connector structure can be elastically deformed, and the resulting repulsive force can cause the outer wall of the male connector structure and the inner wall of the female connector structure to make close contact, which is advantageous for the fixed connection between the female connector structure and the male connector structure. 【0009】 The position-restricting locking groove is formed at the bottom of the male connector structure and has a toothed shape. The elastic sheet is provided with toothed protrusions that engage with the position-restricting locking groove. When the male connector structure is displaced relative to the female connector structure, the toothed protrusions of the elastic sheet are elastically deformed as they separate from the position-restricting locking groove they engage with, and when they align with another position-restricting locking groove, the toothed protrusions return to their original position and engage with that position-restricting locking groove. 【0010】 The elastic sheet includes a pair of U-shaped structures with opposing openings, the tooth-shaped protrusions are connected to the pair of U-shaped structures and located above the pair of U-shaped structures, and the elastic sheet is formed by folding a long elastic sheet. 【0011】 A convex groove is formed on the inner wall of the head frame body, and the convex groove extends into the female connector structure, and the elastic sheet is fitted into the female connector structure by the convex groove. 【0012】 An auxiliary sleeve structure is provided on the side wall of the head frame body. The auxiliary sleeve structure and the female connector structure are aligned front to back and maintain a certain distance from each other. The male connector structure is inserted into the female connector structure after passing through the auxiliary sleeve structure. The auxiliary sleeve structure is advantageous for stable connection between the male connector structure and the head frame. [Effects of the Invention] 【0013】 The handle-extendable head frame of the present invention has a mechanical feel when adjusting the handle position, as the position-limiting locking groove engages with an elastic sheet, allowing the male connector structures at both ends of the handle to be positioned synchronously, thus avoiding differences in the extension width at both ends of the handle. The fastening bolts allow the handle to be fixed in the user's desired position. [Brief explanation of the drawing] 【0014】 The present invention will be further described below with reference to the drawings. 【0015】 [Figure 1] This is a schematic diagram of a handle-retractable head frame. [Figure 2] Figure 1 is an exploded view. [Figure 3] This is a schematic diagram of the elastic sheet 30. [Figure 4] This is a schematic diagram of the elastic sheet 30 from a different perspective. [Figure 5] This is a schematic diagram of handle 20. [Modes for carrying out the invention] 【0016】 As shown in FIGS. 1 and 2, the handle telescopic head frame includes a head frame body 10 and a handle 20. A female connector structure 11 is fixedly provided on the side wall of the head frame body. The handle is U-shaped, and a male connector structure 21 is provided at the end of the handle. A long groove 22 is formed in the male connector structure, and a fastening hole 12 is provided in the female connector structure. A fastening bolt is fitted into the fastening hole. The fastening bolt is located in the long groove. A plurality of position limiting locking grooves 23 are provided in the male connector structure. The plurality of position limiting locking grooves are distributed along the length direction of the male connector structure. An elastic sheet 30 that can engage with any of the position limiting locking grooves is provided in the female connector structure. 【0017】 Both the female connector structure 11 and the male connector structure 21 are hollow and flat. 【0018】 As shown in FIGS. 5 and 3, the position limiting locking groove 23 is formed at the bottom of the male connector structure 11 and is tooth-shaped. The elastic sheet 30 is provided with a tooth-shaped convex portion 31 that engages with the position limiting locking groove. 【0019】 As shown in FIGS. 3 and 4, the elastic sheet 30 includes a pair of U-shaped structures 32 with openings facing each other. The tooth-shaped convex portion 31 is connected to the pair of U-shaped structures and is located above the pair of U-shaped structures. The elastic sheet is formed by bending a long elastic sheet. 【0020】 As shown in FIG. 2, a convex-shaped groove 13 is formed on the inner wall of the head frame body 10. The convex-shaped groove extends into the female connector structure 11, and the elastic sheet 30 is fitted into the female connector structure by the convex-shaped groove. 【0021】 An auxiliary sleeve structure 14 is provided on the side wall of the head frame body 10. The auxiliary sleeve structure and the female connector structure 11 are aligned front and back and have a certain distance. The male connector structure 21 is inserted into the female connector structure after passing through the auxiliary sleeve structure. 【0022】 When the user pulls out or retracts the handle 20 with respect to the head frame body 10, the male connector structure 21 is displaced with respect to the female connector structure 11. When the tooth-shaped convex portion 31 of the elastic sheet disengages from the position-limiting locking groove 23 with which it engages, it is elastically deformed, and when aligning with another position-limiting locking groove, the tooth-shaped convex portion 31 returns and engages with the position-limiting locking groove. According to the displacement amount of the male connector structure 21 with respect to the female connector structure 11, the elastic sheet 30 crosses a predetermined number of position-limiting locking grooves 23 and finally engages with the position-limiting locking groove, thereby initially positioning the handle 20 with respect to the head frame body 10. Thereafter, the user tightens the fastening bolt to clamp the female connector structure 11 to the male connector structure 21 by the fastening bolt, thereby fixing the position of the handle 20 with respect to the head frame body 10. 【0023】 The above content is merely a preferred embodiment of the present invention. Those skilled in the art can make changes in specific embodiments and application ranges based on the idea of the present invention. The content of this specification should not be understood as limiting the present invention. 【Explanation of Reference Numerals】 【0024】 10 Head frame body 11 Female connector structure 12 Fastening hole 13 Convex-shaped groove 14 Auxiliary sleeve structure 20 Handle 21 Male connector structure 22 Longitudinal groove 23 Position-limiting locking groove 30 Elastic sheet 31 Tooth-shaped convex portion 32 U-shaped structure
