Description

A luggage linkage type invisible wheel pull rod

technical field

The invention relates to a luggage linkage type invisible wheel tie rod, which is applied to luggage products, such as backpacks, trolley bags, trolley cases, etc., and is generally installed at the bottom or back of the luggage bag. When necessary, the wheels are opened for dragging, and the wheels are stored when not in use. Make the appearance more beautiful.

Background technique

The trolley is often used on the luggage and is usually used for dragging to save physical strength. Currently, the trolley luggage and the trolley can be well stored in the bag, but the wheels are difficult to store, and the structure is not ideal. The invention discloses a Luggage invisible wheels, when in use, the wheels are rotated and extended. When not in use, the wheels are rotated and stored. After storage, the appearance is flat, compact in structure and beautiful in appearance. For luggage, the appearance is very important, because it is not only a functional purpose. , decorative use is also an important aspect of it. First, an invisible wheel device for undercarriage-type luggage was applied for, application numbers: 2020212686817, 2020106279432. During the implementation process, the wheels need to be taken out manually, and the wheels must be pushed by hand when storing, while Because the wheels are often dragged on the ground, they are very dirty, which will affect the user experience. If the wheels can be linked with the pull rod, the wheels will automatically extend when the pull rod is pulled out, and the wheels will be automatically stored when the pull rod is retracted. This is a very perfect design. .

SUMMARY OF THE INVENTION

Detailed ways

Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These exemplary embodiments are provided so that those skilled in the art can clearly understand the present invention and enable the present invention to be practiced from the description herein. The figures and specific examples are not intended to limit the invention, the scope of which is defined by the appended claims.

It consists of a wheel assembly, a pull rod and a linkage device. The wheel assembly is installed on the back of the backpack. The wheel assembly is provided with a wheel frame, a storage compartment and a cover plate. The pull rod drives the linkage device to link with the wheel frame. When the pull rod is pulled out, the linkage device is linked with the wheel frame, and the wheel frame is rotated out of the storage compartment. When not in use, the pull rod is retracted to drive the linkage device to link with the wheel frame, and the wheel frame is automatically rotated into the storage compartment.

As shown in Figure 1, the bottom plate (9) is installed inside the back panel of the case, the panel (5) is installed on the outside of the back panel of the case and connected to the bottom panel, the bottom panel and the panel are fixed on the back panel of the case, and a cover is installed on the panel (5). The plate (6) is used to cover the wheels, and the storage compartment (10) is arranged on the bottom plate for storage of the wheels.

For the linkage device, the present invention preferably adopts the linkage method of a sliding rod and a crankshaft. When the sliding rod slides up and down, the crankshaft is driven to rotate, so that the wheel frame rotates;

The sliding rod is provided with a chute (13), the chute is connected with the crankshaft (11), and the crankshaft rotates while sliding in the chute.

The linkage device can also be linked by gears and racks. The rack drives the gears to rotate to make the wheel frame rotate. The linkage of gears and racks is also a common method. The drawings in the description are not drawn in detail. Compared with the crankshaft method, there are advantages and disadvantages. The advantage is that the rotation is stable. The disadvantage is that the volume and height are large, it is not easy to install, the structure has no sliding rod, and the crankshaft method is compact. The sliding rod and the crankshaft are simply replaced. It only needs to set the pull rod into a rack, the gear is connected to the rotation shaft of the wheel frame, and the pull rod is pulled to drive the gear to rotate. All the functions of the present invention can also be achieved and the same effect can be achieved. The simple replacement method should include Within the spirit and principle of the present invention, it belongs to the protection scope of the present invention.

As shown in Fig. 9, the pull rod is provided with a sliding block (3), the sliding block slides on the pull rod, and is used to connect the first pull rod and the second pull rod, so that the two pull rods can be extended and retracted. To add another tie rod, just connect the third tie rod to the second tie rod in the same way.

The sliding block is provided with two tie rod mounting holes, which are respectively connected with the two tie rods, so that one tie rod is fixed on the other tie rod and slides on the other tie rod, or the two tie rods slide simultaneously.

Linkage extension and storage method of the pull rod and the wheel frame: As shown in Figures 3, 4, and 5, when extending, first pull the second pull rod to the upper end of the first pull rod. At this time, the second pull rod can no longer be in the first section. The pull rod slides up, and continues to pull the second pull rod to drive the first pull rod upward, the bottom plate makes the first pull rod drive the sliding rod to slide upward under the action of the luggage gravity, the sliding rod drives the crankshaft to rotate, and rotates the wheel frame out of the storage compartment;

When storing, first push the second pull rod to the lower end of the first pull rod. At this time, the second pull rod can no longer slide on the first pull rod. Continue to push the second pull rod to drive the first pull rod to move downward, and the bottom plate is on the ground. Under the action of the supporting force, the first tie rod drives the sliding rod to slide downward, and the sliding rod drives the crankshaft to rotate, and the wheel frame is rotated and received into the storage compartment.

As shown in Figure 5, the contact between the wheel frame and the cover plate is set in an arc shape, the cover plate can slide freely on the wheel frame, the rotation extension and storage of the wheel frame will not be affected by the cover plate, and the cover plate is installed on the rotating shaft Torsion spring, when the wheel frame is put into the storage compartment, the cover plate is automatically closed, and the cover plate can be pushed open when the wheel frame is rotated and extended.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. All within the spirit and principles of the present invention, Any modification, equivalent replacement, improvement, etc. made should be included within the protection scope of the present invention.
