Description

Technical Field

[0001] This utility model relates to the field of mobile component technology, and is a caster and box assembly that can be quickly extended and retracted and has an enhanced support effect. Background Technology

[0002] Currently, most cabinets and lighting fixtures are equipped with fixed casters that cannot be extended or retracted, making it difficult to enhance product stability by adjusting the casters' positions. While a few products on the market are equipped with telescopic support legs, these products mostly use independent caster arm structures, making extension and retraction cumbersome, requiring each caster to be extended individually, and often employing a stacking structure, thus occupying considerable height space. Furthermore, existing telescopic support legs cannot be moved when extended, only when retracted, limiting their usability. Utility Model Content

[0003] The purpose of this utility model is to provide a caster and housing assembly that can be quickly extended and retracted with enhanced support, in order to solve the problems of existing independent caster arm structures having cumbersome extension and retraction operations, occupying a lot of height space, and being unable to move when extended.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A quick-extending caster with enhanced support is characterized by comprising a fixed plate, wherein a groove is provided in the middle of the fixed plate, a hinge shaft is slidably disposed inside the groove, and two symmetrically arranged support legs are hinged on the hinge shaft, with wheels respectively disposed at the ends of the support legs away from the hinge shaft.

[0006] In a preferred embodiment, the wheel axle is arranged parallel to the plane of the fixing plate.

[0007] In a preferred embodiment, wheels are symmetrically arranged on the end of the fixed plate away from the wheels on the support feet.

[0008] A preferred technical solution is a set of casters with retractable wheels that provide enhanced support, comprising a housing, a fixed plate fixedly disposed on the side of the bottom of the housing, a retractable space provided between the middle of the fixed plate and the bottom of the housing, one end of the support leg being slidably disposed inside the retractable space, and the other end of the support leg being located outside the retractable space.

[0009] In a preferred embodiment, the wheel is a swivel wheel.

[0010] In a preferred embodiment, a brake plate is provided on the wheel.

[0011] In a preferred embodiment, a light fixture is mounted on the upper part of the housing via a bracket, and a device for controlling the light fixture is installed inside the housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention enhances product stability while enabling rapid handling and movement, and solves the problem of cumbersome assembly or deployment of product support legs. The support legs extend and retract quickly, and pulling one support leg will automatically extend the other. After being pulled out, the product's horizontal torque and anti-tilting force increase. The casters are omnidirectional wheels, and the retraction and extension of the support legs do not affect the movement of the product. They also have a locking structure with a brake plate, which can reliably fix the product in its current position. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 6 ,

[0023] A quick-extending caster with enhanced support includes a fixed plate 1, a groove 2 in the middle of the fixed plate 1, a hinge shaft 3 slidably disposed inside the groove 2, two symmetrically arranged support legs 4 hinged on the hinge shaft 3, and wheels 5 respectively disposed on the end of the support legs 4 away from the hinge shaft 3.

[0024] The axle of wheel 5 is parallel to the plane of fixed plate 1. This parallel alignment ensures that wheel 5 can smoothly contact the ground and roll when the support leg 4 is extended.

[0025] Wheels 5 are symmetrically arranged on the fixed plate 1 at the end away from the support leg 4. This provides four wheels, enabling the equipment equipped with these casters to move stably in both the retracted and extended states of the support leg 4 via the four-wheel structure.

[0026] A retractable caster assembly with enhanced support includes a housing 6. A fixing plate 1 is fixedly mounted on the side of the bottom of the housing 6. A retractable space is provided between the middle of the fixing plate 1 and the bottom of the housing 6. One end of a support leg 4 is slidably disposed inside the retractable space, and the other end of the support leg 4 is located outside the retractable space. The retractable space between the middle of the fixing plate 1 and the bottom of the housing 6, and the other end of the support leg 4 being slidably disposed inside the retractable space, allows it to extend to support the ground when needed.

[0027] Wheel 5 is a swivel caster. It facilitates flexible turning of the equipment in narrow spaces or complex terrain.

[0028] A brake plate 7 is installed on wheel 5. Pressing the brake plate 7 will lock wheel 5 and prevent the equipment from slipping.

[0029] A light fixture 9 is mounted on the upper part of the housing 6 via a bracket 8, and a device for controlling the light fixture 9 is installed inside the housing 6. This is one application scenario for the casters of this utility model, and it is not necessary for all embodiments. This utility model can also be used in various application scenarios, such as suitcases, storage box sets, large and small box sets, etc.

[0030] This invention enables rapid handling and movement while enhancing product stability, solving the problem of cumbersome assembly or deployment of product support legs. The support legs can be extended or retracted quickly. Pulling one support leg automatically extends the other, increasing the overall horizontal torque and anti-tilting force of the product. The casters are swivel casters, ensuring that product movement is not affected by the retraction or extension of the support legs. The casters also feature a locking mechanism for reliable fixation in the current position.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
