Description

Technical Field

[0001] The utility model relates to the technical field of roller frames, and more specifically to a luggage shock-absorbing roller frame. Background Art

[0002] The existing patent application number is CN201520550190.4, and the patent name is a patent for a shock-absorbing luggage roller frame. The patent discloses a wheel seat with a hinged seat and a movable frame. The movable frame is hingedly mounted on the hinged seat of the wheel seat. The movable frame includes a hinged end and a swing arm. A compressible buffer space cavity is provided between the swing arm and the wheel seat. The swing arm has an open position corresponding to the expanded state of the buffer space cavity and a maximum compression position corresponding to the compressed state of the buffer space cavity. An elastic shock-absorbing mechanism for driving the swing arm to be in the open position is provided between the wheel seat and the movable frame, an initial position limiting structure for limiting the open position of the swing arm and a compression position limiting structure for limiting the maximum compression position of the swing arm, and the initial position limiting structure includes a limit stop protrusion provided on the hinged seat, and a limit surface is provided on the hinged end of the movable frame, and the limit surface is limited by the limit stop protrusion.

[0003] Although the shock-absorbing luggage roller frame in this patent has the advantages of simple and compact structure, few accessories, easy processing and manufacturing, and good structural stability, its spring is too exposed to the outside world. In actual rolling use, some debris such as pebbles can easily get stuck in the spring, causing shock absorption failure, seriously affecting the shock absorption function of the shock-absorbing luggage roller frame, and its overall appearance is poor in aesthetics, affecting the user experience.

[0028] Embodiment 1:

[0029] A luggage shock-absorbing roller frame, such as Figure 1-5 As shown, it includes a wheel seat 1 and a wheel frame 2, a accommodating cavity 19 is arranged below the wheel seat 1, the wheel frame 2 is located in the accommodating cavity 19, and a hinged arm 3 is connected to one side of the wheel frame 2, the hinged arm 3 is hinged to the wheel seat 1, a first elastic positioning structure is arranged above the accommodating cavity 19, a second elastic positioning structure is arranged on the side of the wheel frame 2 away from the hinge, an elastic member is installed between the first elastic positioning structure and the second elastic positioning structure, a rotation guide structure and an anti-detachment structure for preventing the wheel frame 2 from detaching from the accommodating cavity 19 are arranged between the wheel seat 1 and the wheel frame 2.

[0030] The utility model provides an accommodating cavity 19 and arranges the elastic member between the wheel seat 1 and the wheel frame 2 in the accommodating cavity 19, so as to relatively hide and protect the elastic member, and can largely avoid the occurrence of shock absorption failure caused by the jamming of debris. At the same time, the overall structure of the luggage shock-absorbing roller frame is relatively neat and integrated, and the appearance is more beautiful, which can ensure the user's experience.

[0031] In this example, preferably, Figure 1-2 The elastic member includes a first spring 10, and the first spring 10 is installed between the first elastic positioning structure and the second elastic positioning structure. By arranging the first spring 10, the elasticity of the spring is used to perform shock absorption.

[0032] In this example, preferably, Figure 4Described above the accommodating cavity 19, an installation cavity 15 is arranged, the first elastic positioning structure comprises a first upper positioning boss 16, the first upper positioning boss 16 is located in the installation cavity 15, the second elastic positioning structure comprises a first lower positioning boss 8, and the two ends of the first spring 10 are respectively mounted on the first upper positioning boss 16 and the first lower positioning boss 8, thereby realizing the installation of the first spring 10.

[0033] In this example, preferably, Figure 1 As shown, the rotation guide structure includes an arc groove 13 arranged on the wheel seat 1 and an arc block 12 fixed on the wheel frame 2. When the articulated arm 3 drives the wheel frame 2 to rotate, the arc block 12 extends into the arc groove 13, so that the rotation guidance of the wheel frame 2 is achieved by sliding the arc block 12 in the arc groove 13, thereby achieving the effect of precise rotation.

[0034] In this example, preferably, Figure 1-5 As shown, a hinge groove 18 is provided at the bottom of the wheel seat 1, hinge holes 4 are provided on both sides of the hinge groove 18, a connecting hole 7 is provided at the end of the hinge arm 3 away from the wheel frame 2, and the hinge arm 3 extends into the hinge groove 18, and a hinge shaft is installed in the hinge hole 4, and the hinge shaft passes through the connecting hole 7 and the hinge holes 4 on both sides of the hinge groove 18, thereby realizing the hinge connection between the hinge arm 3 and the wheel seat 1, so that the wheel frame 2 can rotate in the accommodating cavity 19 below the wheel seat 1 for shock absorption.

[0035] In this example, preferably, Figure 1-5 As shown, the anti-slip structure includes an anti-slip block 5, which is fixed to the outer side of one end of the articulated arm 3 away from the wheel frame 2. When the articulated arm 3 drives the wheel frame 2 to rotate toward the outside of the accommodating cavity 19, the anti-slip block 5 will contact and abut the outer side of the wheel seat 1 to prevent the articulated arm 3 from continuing to rotate, thereby ensuring that the wheel frame 2 will not slip out of the accommodating cavity 19.

[0036] In this example, preferably, Figure 1-5 As shown, a hidden groove 6 is provided on the wheel seat 1 relative to the anti-slip block 5, and the anti-slip block 5 is located in the hidden groove 6, so that the overall appearance of the outer side of the wheel seat 1 is neat, ensuring the beauty of the appearance.

[0038] Embodiment 2:

[0039] A luggage shock-absorbing roller frame, the other features of which are the same as those of the first embodiment, except that:

[0040] In this example, preferably, a second spring 11 is disposed inside the first spring 10 , and two ends of the second spring 11 are in contact with the wheel seat 1 and the wheel frame 2 respectively.

[0041] Preferably in this example, a second upper positioning boss 17 is provided on the first upper positioning boss 16, a second lower positioning boss 9 is provided on the inner side of the first lower positioning boss 8, and both ends of the second spring 11 are respectively mounted on the second upper positioning boss 17 and the second lower positioning boss 9, thereby realizing the installation of the second spring 11.

[0042] The luggage shock-absorbing roller frame in this embodiment is equipped with a second spring 11, so that the luggage shock-absorbing roller frame 2 can perform shock absorption for luggage of various weight types. When the luggage is light, the elastic force of the first spring 10 is used for shock absorption. When the luggage is heavy and the first spring 10 cannot be compressed and released again for shock absorption, the second spring 11 works (the compression amounts of the first spring 10 and the second spring 11 are different), and can be compressed and released, thereby continuing to achieve the shock absorption function.

[0043] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
