Technical Field
[0001] This utility model relates to the field of air pumps, and more specifically, to a quick disassembly and installation structure for an air pump handle. Background Technology
[0002] As a common gas pressurization tool, the air pump is widely used in scenarios such as inflating bicycle and electric vehicle tires, and filling air devices such as balls and air cushions. With the improvement of people's living standards and the diversification of usage needs, higher requirements have been placed on the portability, ease of use and maintenance convenience of the air pump.
[0003] Traditional air pumps typically use a fixed connection between the handle and the pump body, such as a threaded connection or a snap-fit structure. This fixed connection method has many limitations:
[0004] Firstly, disassembly requires tools, making the process cumbersome;
[0005] Secondly, the handle angle is fixed and cannot be flexibly adjusted according to the usage scenario;
[0006] Thirdly, the threads are prone to wear after long-term use, which can lead to loose connections.
[0007] To address the aforementioned problems, this utility model proposes a quick disassembly and installation structure for an air pump handle. Utility Model Content

[0014] A further preferred embodiment: the gasket is made of rubber.
[0015] A further preferred embodiment: the flange is provided with a through hole for the movement of the steel ball.
[0016] Beneficial effects:
[0017] 1. Equipped with a locking button, spring, slot, slide rail, and limit pin, the pump handle can be quickly disassembled and installed by simply pressing the locking button, without the need for additional tools, greatly improving operational efficiency; the locking mechanism of the steel ball and slot ensures a secure connection, effectively preventing the handle from loosening or falling off during pumping, thus enhancing safety and stability; the detachable limit pin design facilitates future maintenance and replacement of damaged parts, reducing repair costs.

[0025] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.
[0026] Please see Figures 1-5 In this embodiment of the utility model, a quick disassembly and installation structure for an air pump handle includes an air pump body 9 and a handle 1, a connecting seat 6 which is fixedly installed on the handle 1, the connecting seat 6 being sleeved and rotatably mounted on the air pump body 9, a locking button 2 being movably provided inside the connecting seat 6, a flange 10 being detachably connected to the bottom of the connecting seat 6, a locking nut being sleeved and movably mounted on the flange 10, a plurality of steel balls 8 being movably provided inside the flange 10, a slide rail 5 that can drive the steel balls 8 to move on the locking button 2, a through groove 12 being provided through the flange 10, a spring 3 fixedly connected to the locking button 2 being provided inside the through groove 12, and a limiting pin 4 which is detachably installed on the air pump body 9, the limiting pin 4 being able to be inserted into the through groove 12, and a slot 7 being provided on the limiting pin 4 relative to the steel balls 8.
[0027] Specifically, during installation, the connecting seat 6 is fitted onto the air pump body 9, and the flange 10 is connected to the connecting seat 6. At this time, the steel ball 8 is located inside the flange 10. Pressing the locking button 2 compresses the spring 3, and the slide rail 5 on the locking button 2 drives the steel ball 8 to move along the space inside the flange 10. When the limit pin 4 is inserted into the through groove 12, the locking button 2 is released, the spring 3 returns to its original position, and pushes the locking button 2. The steel ball 8 is then engaged in the slot 7 of the limit pin 4, thus locking the handle 1 to the air pump body 9. During disassembly, pressing the locking button 2 again releases the spring 3. When the spring 3 is compressed, the slide rail 5 drives the steel ball 8 to exit from the slot 7, allowing the handle 1 to be removed from the pump body 9. The handle can be quickly disassembled and installed by simply pressing the locking button 2, without the need for additional tools, greatly improving operational efficiency. The locking mechanism between the steel ball 8 and the slot 7 ensures a secure connection, effectively preventing the handle from loosening or falling off during pumping, thus enhancing safety and stability. The detachable limit pin 4 design facilitates future maintenance and replacement of damaged parts, reducing repair costs.
[0028] It should be noted that in this embodiment, there are four steel balls 8, and the design of the slot 7 array supports multiple adjustment positions of the handle from 0° to 180°, thereby improving the versatility of the device. At the same time, disassembly can be completed by pressing the locking button 2, and automatic locking is achieved during installation. The operation process is simplified through the mechanical linkage structure, and the anti-disengagement limit component ensures the structural stability under high vibration scenarios.
[0029] In this embodiment of the utility model, such as Figure 3 and Figure 4 As shown, the locking button 2 has a movable groove 11 inside, which allows the locking button 2 to move. Specifically, the movable groove 11 provides precise movement space and guidance for the locking button 2, ensuring that the locking button 2 can move stably during pressing and resetting, avoiding deviation, jamming and other phenomena, thereby making the driving operation of the locking button 2 on the steel ball 8 smoother, and improving the reliability and service life of the entire quick disassembly and installation structure.
[0030] In this embodiment of the utility model, such as Figure 3 and Figure 4 As shown, the locking button 2 has a fixed ring 14 integrally formed at the bottom. The fixed ring 14 limits the locking button 2 to the movable groove 11. Specifically, the fixed ring 14 ensures that the locking button 2 always moves stably within the movable groove 11, preventing the locking button 2 from accidentally dislodging from the movable groove 11 during use, thus ensuring the normal functioning of the locking button 2. The integrally formed fixed ring 14 structure enhances the overall strength and stability of the locking button 2, reduces the risk of component damage, simplifies the installation process, and improves production efficiency.
[0031] In this embodiment of the utility model, such as Figure 3 and Figure 4 As shown, a washer 15 is movably disposed within the through groove 12. The washer 15 is fixedly connected to the end of the spring 3 away from the locking button 2. The washer 15 is made of rubber. Specifically, the presence of the washer 15 effectively buffers the impact force of the spring 3 during compression and reset, reduces the direct friction and collision between the spring 3 and the inner wall of the through groove 12, protects the spring 3 and the through groove 12, and extends the service life of the spring 3 and the overall structure. At the same time, the washer 15 assists the spring 3 to reset more smoothly, making the operation of the locking button 2 more comfortable and improving the user experience.
[0032] In this embodiment of the utility model, such as Figure 3 and Figure 4 As shown, a through hole 13 is provided on the flange 10 to allow the steel ball 8 to move.
[0033] Working principle: When it is necessary to disassemble handle 1, press the locking button 2 down. The locking button 2 moves downward against the elastic force of spring 3. The slide rail 5 inside it drives the steel ball 8 to move into the flange 10, so that the steel ball 8 is disengaged from the slot 7 of the limit pin 4. At this point, the steel balls 8 no longer restrict the relative movement of the flange 10 and the pump body 9, allowing the flange 10, along with the connecting seat 6 and handle 1, to be easily removed from the pump body 9, completing the disassembly process. When it is necessary to install the handle 1 onto the pump body 9, first, place the connecting seat 6 onto the pump body 9, bringing the flange 10 close to the upper limit pin 4 of the pump body 9. At this time, multiple steel balls 8 are located inside the flange 10. Due to the initial state of the slide rail 5 on the locking button 2, some of the steel balls 8 protrude outside the through hole 13 of the flange 10. Align the flange 10 with the limit pin 4 on the pump body 9, and press the handle 1 firmly to make the steel balls 8 contact the limit pin 4. Under pressure, the steel balls 8 are blocked by the limit pin 4 and retract into the flange 10, while simultaneously pushing... Locking button 2 moves upward against the elastic force of spring 3, providing space for the retraction of steel ball 8 in slide rail 5. When the through groove 12 on flange 10 is fully aligned with limit pin 4, spring 3 pushes locking button 2 to reset. Under the action of spring 3 and slide rail 5, steel ball 8 is inserted into the slot 7 of limit pin 4, thus achieving a fixed connection between handle 1 and pump body 9. At this time, the pump handle is installed and can be used normally. Secondly, when it is necessary to adjust the angle of handle 1, after unlocking, rotate the handle to the target angle, and then let limit pin 4 embed into the corresponding slot 7. The overall operation steps are simple, enabling one-handed operation, tool-free handle separation and locking functions, and multi-angle adjustment of handle 1, improving the versatility of the device.
