[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] like Figures 1 to 10As shown, a wheel axle assembly with an anti-disengagement function provided in one embodiment of the present application includes a wheel axle 10 , a latch pin 20 , a baffle plate 30 and a clip hook 40 .

[0029] In the present application, a wheel axle 10 is provided with a slot 101 on one end 11 in the axial direction, and a waist-shaped hole 102 is provided on the peripheral wall 12 in the radial direction, and the waist-shaped hole 102 is connected to the slot 101; a latch 20 is movably arranged in the waist-shaped hole 102; two clamping hook holes 31 are provided on the baffle 30, and a clamping hook 40 can pass through the two clamping hook holes 31 and be inserted into the slot 101, so as to limit the baffle 30 on the wheel axle 10 with the clamping hook 40; and the portion of the clamping hook 40 inserted into the slot 101 can be engaged with the latch 20, so as to limit the clamping hook 40 from being separated from the baffle 30 with the latch 20. That is to say, when the wheel axle assembly of the present application is working, the clamping hook 40 can be used to limit the baffle 30 on the wheel axle 10, and the clamping hook 40 is limited to the wheel axle 10 by the latch 20, so as to specifically realize the limit fixation of the baffle 30 on the wheel axle 10. It should be noted that the clamp hook 40 cooperates with the latch pin 20 in a barbed manner, so as to achieve the position limiting of the clamp hook 40 on the wheel axle 10 by the latch pin 20 .

[0030] It can be understood that the clamp hook 40 is specifically limited on the wheel axle 10 by the latch pin 20, and the clamp hook 40 is snap-fitted with the latch pin 20 to improve the effect of preventing the clamp hook 40 from being detached from the wheel axle 10.

[0031] In one embodiment, the clamp hook 40 includes a connecting arm 41 and two clamp arms 42 located at both ends of the connecting arm 41, wherein each clamp arm 42 is provided with a guide slope 421, and a step surface 422 is formed at the end position of the guide slope 421, and the guide slopes 421 on the two clamp arms 42 cooperate to form a guide opening 401, and the two step surfaces 422 can be used to abut the latch 20 to limit the latch 20 from detaching from the clamp hook 40, thereby specifically realizing the structural setting of the clamp hook 40. When the clamp hook 40 cooperates with the latch pin 20, the clamp hook 40 can open the two clamp arms 42 under the guidance of the guide slope 421 at the position of the guide opening 401. As the latch pin 20 moves on the guide slope 421, when the latch pin 20 breaks away from the guide slope 421 and enters the position where the step surface 422 is located, the two clamp arms 42 are reset under elastic deformation, thereby achieving the pressure and limitation of the step surface 422 on the clamp hook 40 on the latch pin 20, that is, achieving the cooperation between the clamp hook 40 and the latch pin 20.

[0032] The two clamping arms 42 and the connecting arm 41 are configured as an integrated structure, and the two clamping arms 42 can be opened and closed relative to the connecting arm 41 to meet the use requirements of the clamping hooks 40 and the latch 20. It should be noted that the clamping hooks 40 can be specifically configured as steel sheets with a certain elasticity, which will not be elaborated here.

[0033] In one embodiment, the latch pin 20 is configured as a round head pin, and both ends of the round head pin are configured as arc structures, so that when a wheel is installed on the wheel axle 10 (not shown in the figure), a sliding bearing 201 can be installed between the wheel axle 10 and the wheel. The sliding bearing 201 can wrap the openings at both ends of the waist-shaped hole 102 to limit the latch pin 20 from being separated from the wheel axle 10. The arc structure at the end of the round head pin is utilized to make the round head pin always in a tilted state to prevent the round head pin from staying in the gap between the two step surfaces 422 on the pair of clamp hooks 40, thereby further preventing the pair of clamp hooks 40 from being detached from the latch pin 20.

[0034] In addition, it should be noted that the axle assembly further includes an ejector block 50 and a hook pull rod 60, the ejector block 50 is disposed at the bottom of the slot 101, and the hook pull rod 60 can drive the ejector block 50 to act on the clamp hook 40 to drive the clamp hook 40 to disengage from the latch 20. In other words, when the axle assembly of the present application is working, the ejector block 50 and the hook pull rod 60 can be used to disengage the clamp hook 40 from the latch 20.

[0035] In one embodiment, the number of hook pull rods 60 is two, and two pull rod holes 32 matching the hook pull rods 60 are opened on the baffle 30. The two pull rod holes 32 are separated on the two outer sides of the clamping hook hole 31, and the two hook pull rods 60 can pass through the corresponding pull rod holes 32 and be connected to the ejection block 50, so as to specifically realize the number setting of the hook pull rods 60 and specifically realize the use requirement of inserting the hook pull rods 60 into the slot 101.

[0036] Among them, the hook pull rod 60 is provided with a right-angle hook 61, and the ejection block 50 is provided with a right-angle groove 51 matching the right-angle hook 61. The hook pull rod 60 can be locked and matched with the ejection block 50 through the cooperation between the right-angle hook 61 and the right-angle groove 51.

[0037] Specifically, the right-angled hook 61 on the hook pull rod 60 can be first inserted into the right-angled groove 51 of the ejection block 50, and then the hook pull rod 60 can be driven to rotate 90°, so that the hook pull rod 60 after rotating 90° can enter the other groove of the right-angled groove 51, and realize the abutment and limiting between the right-angled hook 61 and the groove wall of the right-angled groove 51 on the ejection block 50, and then pulling the hook pull rod 60 can drive the ejection block 50 to move in the direction of the clamping hook 40, and realize the support of the clamping hook 40, so that the clamping hook 40 can be unlocked from the pin 20.

[0038] In one embodiment, a protruding tip portion 52 is provided on the ejection block 50 , and the ejection block 50 can drive the protruding tip portion 52 to prop up the clamping hook 40 , so as to release the locking of the clamping hook 40 by the latch 20 .

[0039] In summary, the wheel axle assembly with anti-disengagement function of the present invention, through the above-mentioned reasonable structural setting, uses the clamping hook to press the baffle against the wheel axle, and the clamping hook is pressed and limited by the pin arranged in the wheel axle, and the abutment cooperation between the clamping hook and the pin is used to limit the position, which can prevent the clamping hook from being separated from the pin due to factors such as vibration, and then play the role of disengagement to meet the use requirements of on-site working conditions; at the same time, the wheel axle assembly has a simple structure and is easy to assemble, which further meets the use requirements of enterprises.
