Description

Technical Field

[0001] This utility model relates to bracket structures, and more particularly to a bracket structure for a golf bag trolley. Background Technology

[0002] Existing golf bag carts typically include a frame, handlebars, front wheels, left rear wheels, right rear wheels, and two support brackets: an upper bag support and a lower bag support. The handlebars are mounted on top of the frame, the front wheels are mounted on the frame at the front, the left rear wheels are mounted on the left side of the frame, the right rear wheels are mounted on the right side, the lower bag support is mounted at the bottom of the frame, and the upper bag support is mounted at the top. In use, the bottom of the bag is supported by the lower bag support, while the top of the bag is inserted into the upper bag support and secured by buckles or straps on the upper bag support.

[0003] However, in existing golf bag trolleys, both the upper and lower bag holders are fixed to the frame, and the distance between them is fixed, meaning they can only support bags of a specific height. Golf bags, however, come in different sizes to suit different age groups, such as children's bags, kids' bags, and adult bags. Therefore, different sized bags have different heights, and existing golf bag trolleys are only suitable for bags taller than the distance between their upper and lower holders, lacking versatility. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a golf bag trolley bracket structure that can be used as an upper or lower golf bag bracket, and is height-adjustable after being installed on a golf bag trolley, so as to be suitable for supporting golf bags of different sizes and thus improve the versatility of the golf bag trolley.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows: a bracket structure for a golf bag trolley, including a support bracket, which is mounted on the frame of the golf bag trolley via a parallel linkage mechanism; the parallel linkage mechanism includes a connecting seat, a mounting seat, and two parallel linkage assemblies; the connecting seat is used to fix itself to the frame of the golf bag trolley; the mounting seat is fixed to the rear side of the support bracket and located in front of the connecting seat; the two parallel linkage assemblies are a left parallel linkage assembly and a right parallel linkage assembly; the left parallel linkage assembly is mounted on the left side of the mounting seat and the connecting seat, and can be locked or rotated relative to the mounting seat and the connecting seat. The right parallel link assembly is mounted on the right side of the mounting base and the connecting base, and can be locked or rotated relative to the mounting base and the connecting base; the left parallel link assembly and the right parallel link assembly are symmetrical; the mounting base is provided with a first mounting hole that passes through from left to right; the left part of the first mounting hole is provided with a left inner ring tooth structure, the right part is provided with a right inner ring tooth structure, and an embedded block is fixedly provided in the middle; the left parallel link assembly includes a first link, a second link, a gear plate, an elastic element, a snap fastener, a first nut, and a first fixing rod; the first link and the second link are both located on the left side of the connecting base and the mounting base, the first link is located above the second link, and both are... Parallel arrangement; the rear parts of the first and second connecting rods are rotatably mounted on the connecting seat, and the front part of the second connecting rod is rotatably mounted on the mounting seat; a second mounting hole recessed to the left is provided on the right side of the front part of the first connecting rod, and the second mounting hole is connected to the first mounting hole from left to right; a first inner ring tooth structure is provided in the second mounting hole, and the first inner ring tooth structure and the left inner ring tooth structure are connected to form a complete inner ring tooth structure from left to right; the first nut, the toothed disc, and the snap fastener are arranged sequentially from right to left; a third mounting hole penetrating from left to right is provided on the embedded block, and the first nut is fixed in the third mounting hole; when When the left parallel link assembly is locked, the gear plate engages with both the left inner ring tooth structure and the first inner ring tooth structure; when the left parallel link assembly can rotate, the gear plate engages only with the left inner ring tooth structure; the elastic element is located in the first mounting hole, with its left end fixed to the mounting base and its right end fixed to the gear plate; the first fixing rod passes sequentially through the front part of the first link, the gear plate, the elastic element, and the first nut, and is threadedly connected to the first nut; a rightwardly extending moving channel is provided on the left side of the front part of the first link, and the moving channel communicates with the second mounting hole; the snap fastener is disposed in the moving channel and connected to the gear plate;When the snap button is subjected to pressure from left to right, it can move a preset distance to the right along the moving channel, causing the toothed disc to change from engaging with both the left inner ring tooth structure and the first inner ring tooth structure to engaging only with the left inner ring tooth structure.

[0006] Compared with the prior art, the advantage of this utility model lies in the parallel linkage mechanism composed of a connecting seat, a mounting seat, a left parallel linkage assembly, and a right parallel linkage assembly. The left parallel linkage assembly consists of a first link, a second link, a gear plate, an elastic element, a snap fastener, a first nut, and a first fixing rod, and it has a left-right symmetrical structure with the right parallel linkage assembly. When the left parallel linkage assembly is locked, the snap fastener is located at its leftmost position, and the gear plate is simultaneously located in the first mounting hole and the second mounting hole, respectively engaging with the left inner ring tooth structure and the first inner ring tooth structure. At this time, due to the limitation of the gear plate, neither the first link nor the second link can rotate relative to the connecting seat and the mounting seat. If a rightward pressing force is applied to the snap fastener, causing the snap fastener to move to the right, the snap fastener will synchronously push the gear plate to the right and compress the elastic element. When the snap fastener moves a preset distance... The first link will then block the gear, at which point the gear plate will leave the second mounting hole and be completely inside the first mounting hole, engaging only with the left inner ring gear structure. The gear plate will release the lock on the first link, allowing the first link to rotate around the first fixed rod under force. The right parallel link assembly will also release its lock in the same way. After both the left and right parallel link assemblies are released, the support bracket can be lifted upwards or pressed downwards. At this time, the first and second links in the left parallel link assembly will form a parallel link that can rotate, and the right parallel link assembly will also rotate in the same way. Thus, the support bracket can rise or fall, achieving height adjustment. Therefore, this utility model, as an upper or lower golf bag support bracket, can be installed on a golf bag trolley with adjustable height, making it suitable for golf bags of different sizes and improving the versatility of the golf bag trolley.

[0007] Furthermore, a slot is provided in the front part of the first connecting rod, and the snap fastener is limited by engaging with the slot through a snap fastener located thereon.

[0008] Furthermore, the elastic element is a spring.

[0009] Furthermore, the rear portion of the first connecting rod and its symmetrical portion in the right parallel connecting rod assembly are mounted on the connecting seat via a second fixing rod and fixed by a second nut threadedly connected to the second fixing rod; the rear portion of the second connecting rod and its symmetrical portion in the right parallel connecting rod assembly are mounted on the connecting seat via a third fixing rod and fixed by a third nut threadedly connected to the third fixing rod; the front portion of the second connecting rod and its symmetrical portion in the right parallel connecting rod assembly are mounted on the mounting seat via a fourth fixing rod and fixed by a fourth nut threadedly connected to the fourth fixing rod.

[0010] Furthermore, the left inner ring tooth structure, the right inner ring tooth structure, and the first inner ring tooth structure are respectively implemented by racks that are evenly spaced along a circle. Attached Figure Description

The parallel linkage mechanism includes a connecting seat 2, a mounting seat 3, and two parallel linkage assemblies. The connecting seat 2 is fixed to the frame 4 of the golf bag trolley. The mounting seat 3 is fixed to the rear side of the support frame 1 and located in front of the connecting seat 2. The two parallel linkage assemblies are a left parallel linkage assembly 5 and a right parallel linkage assembly 6. The left parallel linkage assembly 5 is mounted on the left side of the mounting seat 3 and the connecting seat 2 and can be locked or rotated relative to the mounting seat 3 and the connecting seat 2. The right parallel linkage assembly 6 is mounted on the right side of the mounting seat 3 and the connecting seat 2 and can be locked or rotated relative to the mounting seat 3 and the connecting seat 2. The mounting base 3 and the connecting base 2 are locked or rotated; the left parallel link assembly 5 and the right parallel link assembly 6 are symmetrical; the mounting base 3 is provided with a first mounting hole that passes through from left to right; the left part of the first mounting hole is provided with a left inner ring tooth structure 7, the right part is provided with a right inner ring tooth structure, and the middle part is fixedly provided with an embedded block 8; the left parallel link assembly 5 includes a first link 9, a second link 10, a toothed disc 11, an elastic element 12, a snap fastener 13, a first nut 14, and a first fixing rod 15; the first link 9 and the second link 10 are both located on the left side of the connecting base 2 and the mounting base 3, with the first link 9 located above the second link 10, and the two are arranged parallel to each other; the rear parts of the first link 9 and the second link 10 are respectively rotatably mounted on the connecting base 2. The front part of the second connecting rod 10 is rotatably mounted on the mounting base 3; the front right side of the first connecting rod 9 has a second mounting hole recessed to the left, which is connected to the first mounting hole; a first inner ring tooth structure 16 is provided in the second mounting hole, which is connected to the left inner ring tooth structure 7 to form a complete inner ring tooth structure; the first nut 14, the toothed disc 11, and the snap fastener 13 are arranged sequentially from right to left; the embedded block 8 has a third mounting hole 17 that runs through it from left to right, and the first nut 14 is fixed in the third mounting hole 17; when the left parallel connecting rod assembly 5 is locked, the toothed disc 11 engages with the left inner ring tooth structure 7 and the first inner ring tooth structure 16 respectively; when the left parallel connecting rod assembly 5 can rotate... At this time, the gear disk 11 only engages with the left inner ring tooth structure 7; the elastic element 12 is located in the first mounting hole, with its left end fixed to the mounting base 3 and its right end fixed to the gear disk 11; the first fixing rod 15 passes through the front part of the first connecting rod 9, the gear disk 11, the elastic element 12 and the first nut 14 in sequence, and is threadedly connected to the first nut 14; a moving channel extending to the right is provided on the left side of the front part of the first connecting rod 9, and the moving channel communicates with the second mounting hole; the snap fastener 13 is provided in the moving channel and is connected to the gear disk 11; when the snap fastener 13 is subjected to pressure from left to right, it can move a preset distance to the right along the moving channel, so that the gear disk 11 changes from engaging with the left inner ring tooth structure 7 and the first inner ring tooth structure 16 to engaging only with the left inner ring tooth structure 7.

[0014] In this embodiment, when the left parallel linkage assembly 5 is locked, the snap 13 is located at its leftmost position (i.e., the leftmost position of the moving channel). The gear plate 11 is simultaneously located in the first mounting hole and the second mounting hole, and engages with the left inner ring tooth structure 7 and the first inner ring tooth structure 16 respectively. At this time, due to the limitation of the gear plate 11, neither the first link 9 nor the second link 10 can rotate relative to the connecting seat 2 and the mounting seat 3. If a rightward pressing force is applied to the snap 13, causing the snap 13 to move to the right, the snap 13 will synchronously push the gear plate 11 to the right and compress the elastic element 12. When the snap 13 moves a preset distance, it will be blocked by the first link 9. At this time, the gear plate 11 leaves the second mounting hole and is completely located in the first mounting hole. Engaging only with the left inner ring tooth structure 7, the locking of the toothed disc 11 to the first connecting rod 9 is released, and the first connecting rod 9 can rotate around the first fixed rod 15 under force; the right parallel connecting rod assembly 6 can also be unlocked in the same way; after both the left parallel connecting rod assembly 5 and the right parallel connecting rod assembly 6 are unlocked, the support bracket 1 is lifted upward or pressed downward. At this time, the first connecting rod 9 and the second connecting rod 10 in the left parallel connecting rod assembly 5 form a parallel connecting rod that can rotate, and the right parallel connecting rod assembly 6 can also rotate in the same way, so that the support bracket 1 can rise or fall to achieve height position adjustment. After the adjustment is completed, the snap 13 is released, the elastic element 12 is reset, and the left parallel connecting rod assembly 5 and the right parallel connecting rod assembly 6 are locked, and the support bracket 1 is fixed.

[0015] Example 2: This example is basically the same as Example 1, except that: In this example, a slot 18 is provided in the front part of the first connecting rod 9, and the snap fastener 13 is limited by the snap fastener 131 provided therein cooperating with the slot 18.

[0016] Example 3: This example is basically the same as Example 1, except that in this example, the elastic element 12 is a spring.

[0017] Example 4: This example is basically the same as Example 1, except that: In this example, the rear part of the first connecting rod 9 and its symmetrical part in the right parallel connecting rod assembly 6 are mounted on the connecting seat 2 by the second fixing rod 19 and fixed by the second nut 20 threadedly connected to the second fixing rod 19; the rear part of the second connecting rod 10 and its symmetrical part in the right parallel connecting rod assembly 6 are mounted on the connecting seat 2 by the third fixing rod 21 and fixed by the third nut 22 threadedly connected to the third fixing rod 21; the front part of the second connecting rod 10 and its symmetrical part in the right parallel connecting rod assembly 6 are mounted on the mounting seat 3 by the fourth fixing rod 23 and fixed by the fourth nut 24 threadedly connected to the fourth fixing rod 23.

[0018] In this embodiment, the first link 9 and its symmetrical portion in the right parallel link assembly 6 are mounted on the connecting seat 2 using the same components. The rear part of the second link 10 and its symmetrical portion in the right parallel link assembly 6 are also mounted on the connecting seat 2 using the same components. This simplifies the installation process and ensures the ease of operation of the left parallel link assembly 5 and the right parallel link assembly 6.

[0019] Example 5: This example is basically the same as Example 1, except that in this example, the left inner ring tooth structure 7, the right inner ring tooth structure and the first inner ring tooth structure 16 are respectively implemented by a toothed rack that is evenly spaced along a circle.

[0020] In this embodiment, the rack and pinion engagement enables circumferential limiting while also allowing axial force-bearing movement. Thus, circumferential unlocking can be achieved by pressing the snap button 13, simplifying the height adjustment operation of the support bracket 1.

[0021] In summary, when this utility model is installed on the frame 4 of a golf bag trolley as an upper or lower golf bag support, the height of the support frame 1 can be adjusted according to the size of the golf bag to meet the support needs of golf bags of different sizes, thereby improving the versatility of the golf bag trolley and having broad application prospects.
