Description
Technical Field
[0001] The utility model relates to the field of child strollers, in particular to an anti-slip mechanism of a child stroller. Background Art
[0002] A stroller is a device used to facilitate parents to carry their babies when traveling. When traveling, cushions and other supporting materials can be laid inside it first, and then the baby to be carried can be placed inside it. There are usually multiple sets of mobile wheels at the bottom of the stroller, which can facilitate the user to move the entire device.
[0003] When an existing child stroller is in use, the vehicle is usually fixed by relying on the locking function of the moving wheels at the bottom thereof. Although the device can be fixed, since the contact mode between the moving wheels and the ground is line contact, the moving wheels cannot provide a large friction area and friction force after being locked, and the entire device may still slide. The anti-skid ability of the entire device is poor. Therefore, an anti-skid mechanism for a child stroller is proposed to solve the above problem. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an anti-skid mechanism of a child stroller, comprising a frame 2 for supporting the overall device, a body 1 for accommodating a baby is installed on the top of the frame 2, a sunshade is arranged on the top of the body 1, which can play a sunshade effect, a support shaft 3 for supporting a support frame 5 is passed through and fixedly connected at the front end of the frame 2, a support frame 5 for supporting a moving wheel 6 is rotatably connected at the front end of the support shaft 3, a moving wheel 6 for supporting the movement of the overall device is installed at the bottom end of the support frame 5, a push handle 4 for facilitating an operator to push the overall device is fixedly connected to the outer wall of the support shaft 3, an adjusting component 7 for adjusting the position of the support frame 5 is arranged at the front end of the frame 2, and a supporting component 8 for supporting the overall device when fixed is arranged at the right end of the support frame 5.
[0030] Reference Figure 1 - Figure 3 The adjusting assembly 7 includes a slide plate 71 for driving the support frame 5 to rotate. The rear end of the slide plate 71 is slidably connected to the front end of the frame 2. The slide plate 71 can slide up and down at the front end of the frame 2 and cannot be separated from the front end of the frame 2. The right end of the support frame 5 is provided with a gear tooth 76 for driving the support frame 5 to rotate. The gear tooth 76 and the slide plate 71 are meshed with each other. When the slide plate 71 moves up and down, the gear tooth 76 will be driven to rotate. The front end of the slide plate 71 is fixedly connected with a handle 72 for facilitating the operator to move the slide plate 71. The rear end of the handle 72 is slidably connected with a shift block 73 for fixing the slide plate 71. The front end of the frame 2 is provided with an adjusting groove 75 for accommodating the shift block 73. The shift block 73 is adapted to the adjusting groove 75. When the shift block 73 is stuck in the adjusting groove 75, the shift block 73 will be fixed and cannot move up and down.
[0031] Reference Figure 1 - Figure 3 The rear end of the slider 73 is fixedly connected to the front end of the slider 71, and the slider 71 will also be fixed and cannot move up and down. The rear end of the slider 73 is fixedly connected to a return spring 74 for pulling the slider 73. The rear end of the return spring 74 is fixedly connected to the front end of the slider 71, and the return spring 74 will always pull the slider 73 to the left to prevent it from arbitrarily escaping from the inside of the adjustment slot 75. The support frame 5 and the gear teeth 76 are provided with multiple groups. The multiple groups of support frames 5 and the gear teeth 76 are symmetrically arranged with the center line of the slider 71 as the symmetry axis. The left end of the other group of gear teeth 76 is meshed with the right end of the slider 71. When the slider 71 moves up and down, the two groups of support frames 5 will be driven to rotate synchronously.
[0032] Reference Figure 1 - Figure 3 The support assembly 8 includes a sleeve 81 for supporting a support foot 82. The left end of the sleeve 81 is fixedly connected to the bottom end of the support frame 5 near the right end. The bottom end of the sleeve 81 is slidably connected to a support foot 82 for supporting the entire device. The bottom end of the support foot 82 is made of rubber, which can provide a large friction force when in contact with the ground. The top of the support foot 82 is fixedly connected to a piston block 83 for alleviating the up and down movement of the support foot 82. The piston block 83 penetrates and is slidably connected to the inner wall of the sleeve 81. When the piston block 83 moves up and down inside the sleeve 81, a large friction force is generated, which can force the support foot 82 and the sleeve 81 to remain stationary. The top of the piston block 83 is fixedly connected to a support spring 84 for pushing the support foot 82 downward. The top of the support spring 84 is fixedly connected to the inner wall of the sleeve 81, and the support spring 84 will always push the support foot 82 downward.
[0033] Working principle: when the entire device needs to be fixed, the shift block 73 can be pushed outward first to drive the shift block 73 to move forward and disengage from the inside of the adjustment slot 75, and then the handle 72 can be moved downward to drive the slide plate 71 to move downward synchronously. When the slide plate 71 moves downward, it will drive the gear teeth 76 to rotate, and the rotation of the gear teeth 76 will drive the support frame 5 to rotate outward, so that the bottom end of the support foot 82 will contact the ground and the moving wheel 6 will be off the ground. Then the shift block 73 can be released, and the reset spring 74 will pull the shift block 73 to move backward and re-enter the inside of the adjustment slot 75. At this time, the slide plate 71 will be re-fixed, and the entire device will ground the support foot 82. Compared with the moving wheel 6, the grounding area of the support foot 82 is larger, so the overall device has better stability when fixed.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
