Description

Technical Field

[0001] This utility model belongs to the field of non-motorized vehicles, and specifically relates to an upper and lower bowl pressing mechanism. Background Technology

[0002] The headset (also called the head tube assembly) of bicycles and electric bikes is a key component that connects the seat tube of the fork to the steerer tube of the fork. Its main function is to ensure that the fork can steer flexibly while keeping the front of the bike stable and not wobbling.

[0003] The headset consists of an upper and an lower headset. The lower headset is installed inside the head tube (top of the front triangle) of the frame and usually integrates a bearing (ball bearing or sealed bearing). The upper headset is installed on top of the fork steerer tube and also contains a bearing. Together, they wrap around the fork steerer tube, forming a "bearing + headset" structure that allows the steerer tube to rotate smoothly.

[0004] To prevent uneven pre-compression during installation, installation tools are required.

[0005] Chinese Patent CN223070867U discloses a pressing device for pressing a headset assembly into the head tube of a bicycle, comprising a frame, a positioning component, a pressing component, and a pressing component. The positioning component is mounted on the frame and is used to secure the head tube of the bicycle. The pressing component is mounted on the frame. The pressing component is mounted on the frame and includes a fixing plate connected to the frame, a first drive member mounted on the fixing plate, and a buffer pad connected to the first drive member.

[0006] The above technical solution has the following drawbacks:

[0007] During the installation process, the frame needs to be manually supported to maintain its stability and level in order to ensure the accuracy of the subsequent installation of the upper and lower cups. However, for manual labor, hand fatigue is inevitable, which may lead to adjustments and reinstallation, affecting the overall processing efficiency. Utility Model Content

[0008] To address the above deficiencies, this utility model provides an upper and lower bowl pressing mechanism, including a frame, an operating chamber installed on the top of the frame, and pressing and abutting mechanisms installed at the upper and lower ends of the operating chamber, as well as a support mechanism for fixing the frame.

[0009] The support mechanism includes a head tube seat for positioning the head tube and an upper tube support for supporting the upper tube.

[0010] The first tube seat passes through the operating chamber via a connecting rod and is connected to the first crossbar. Support plates are installed on the left and right ends of the first crossbar, and connecting blocks are slidably installed on the bottom ends of the two support plates. The two connecting blocks are connected by a second crossbar, which passes through the upper tube and fixes it. The bottom ends of the two connecting blocks are inserted into several limiting holes opened on the top of the frame via telescopic rods.

[0011] Furthermore, a vertical groove is provided at one end of the operating chamber through which the connecting rod passes, allowing the connecting rod to move up and down.

[0012] Furthermore, the two ends of the first crossbar are threadedly connected to the screw holes opened in the opposite side support plate through the first thread layer.

[0013] Furthermore, a groove is provided at the bottom end of the support plate, and the top end of the connecting block is slidably connected to the groove through a fixed T-shaped slider.

[0014] Furthermore, the second crossbar is movably connected to the through slot opened in the upper support tube, and the outer ring of the second crossbar is provided with a set of second thread layers. Each of the two second thread layers is threadedly connected to a limiting nut. The two limiting nuts are used to clamp and limit the upper support tube.

[0015] Furthermore, the front of the first tube seat is provided with a groove I that is adapted to the first tube, and the upper surface of the upper tube is provided with a groove II for the upper tube to be adapted.

[0016] Furthermore, rubber pads are attached to both groove I and groove II.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] Compared to existing pressing devices, a stabilizing mechanism for the frame has been added. When pressing and inserting the upper and lower cups, there is no need for continuous manual support to maintain a horizontal state, preventing deviations caused by prolonged manual operation, thus ensuring the accuracy and stability of the installation of the upper and lower cups.

[0019] Meanwhile, the entire system uses a threaded connection, which makes subsequent disassembly and maintenance easier. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example

[0025] like Figures 1 to 2 As shown, this embodiment provides an upper and lower bowl pressing mechanism, including a frame 1, an operating chamber 4 installed on the top of the frame 1, and a pressing mechanism 3 and an abutting mechanism 2 installed on the upper and lower ends of the operating chamber 4, and also includes a support mechanism for fixing the frame.

[0026] It should be noted that the pressing mechanism 3 and the abutting mechanism 2 are the same in structure and principle as those in existing equipment. For reference, Chinese Patent No. CN223070867U discloses a structure for pressing a headset assembly into a bicycle head tube, which will not be described in detail here.

[0027] The support mechanism includes a head tube seat 6 for positioning the head tube and an upper tube support 18 for supporting the upper tube. The front of the head tube seat 6 is provided with a groove I that is adapted to the head tube, and the upper surface of the upper tube support 18 is provided with a groove II for the upper tube to be adapted. Rubber pads 20 are attached to both groove I and groove II, which can prevent wear on the frame and increase friction to ensure wrapping of the outer surface of the frame and achieve stable pressing.

[0028] The head tube seat 6 passes through the vertical slot 5 opened at the operating compartment 4 via the connecting rod 10 and is connected to the first crossbar 7 (the through-hole provides support between the connecting rod 10 and the first crossbar 7), allowing the connecting rod 10 to move up and down. The left and right ends of the first crossbar 7 are respectively threaded to the screw holes 12 opened at the opposite side support plate 8 via the first thread layer 11. The bottom ends of the two support plates 8 are slidably installed with connecting blocks 13. In detail, the bottom end of the support plate 8 is provided with a sliding groove, and the top end of the connecting block 13 is slidably connected to the sliding groove via a fixed T-shaped slider 14. Its function is to allow for position adjustment for frames of different sizes.

[0029] The two connecting blocks 13 are connected by a second crossbar 15, which passes through the upper support tube 18 and fixes it. The second crossbar 15 is movably connected to the through slot 19 opened in the upper support tube 18. A set of second threaded layers 16 are opened on the outer ring of the second crossbar 15. Each of the two second threaded layers 16 is threadedly connected to a limiting nut 17. The two limiting nuts 17 are used to clamp and limit the upper support tube 18. The bottom ends of the two connecting blocks 13 are inserted and connected to several limiting holes opened on the top of the frame 1 through telescopic rods 21 to adapt to the position of the T-shaped slider 14.

[0030] The upper and lower bowl pressing mechanism described in this embodiment allows the pressing mechanism 3 and the abutting mechanism 2 to be operated after the first tube of the frame is placed in slot I and the upper tube is placed in slot II. At the same time, the employee does not need to use their hands to support the frame. Stable pressing can be achieved by positioning slots I and II (limiting the vertical and horizontal positions respectively).

[0031] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
