Description

Technical Field

[0002] With the continuous development of the sericulture industry, the silkworm platform, as an indispensable equipment in the sericulture process, is also constantly being optimized and innovated in design and function. Traditional silkworm platforms are mostly fixed structures. Although they have good stability, they are inconvenient in actual use, especially in breeding environments where the position of the silkworm platform needs to be adjusted frequently. In order to solve this problem, mobile silkworm platforms came into being. They install casters or universal wheels at the bottom of the silkworm platform to achieve convenient movement of the silkworm platform.

[0003] However, while existing mobile silkworm platforms provide convenience, they also bring some technical problems. First, due to the rolling characteristics of the casters, the stability of the silkworm platform in a stationary state is poor, especially when the ground is uneven or the load is uneven, it is easy to shift, posing a safety hazard to sericulture. Secondly, existing mobile silkworm platforms often lack an effective locking mechanism. Once the caster locking fails, the stability of the silkworm platform cannot be guaranteed. In addition, the pressure of the mobile silkworm platform on the ground is unevenly distributed during movement, which may cause early wear or damage to the silkworm platform structure or the ground.

[0004] In view of the above problems, although some improvement measures have been proposed, such as increasing the weight of the silkworm platform, improving the caster design, etc., these measures often sacrifice the lightness and mobility of the silkworm platform, and fail to fundamentally solve the contradiction between stability and mobility.

[0049] The following is a description with reference to the accompanying drawings and a specific embodiment.

[0050] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are 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. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the utility model.

[0051] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in the subsequent drawings.

[0052] See also Figures 1 to 5 The mobile silkworm platform described in this embodiment includes a bed frame 100, which is composed of four columns 110. The columns 110 are connected to each other through a top crossbeam 120 and a bottom crossbeam 130 to form a stable frame structure.

[0053] A wheel compartment 111 is provided at the bottom of the column 110, and a telescopic wheel assembly is installed in the wheel compartment 111. The inner cavity height of the wheel compartment 111 is greater than the retracted height of the telescopic wheel assembly and less than the extended height of the telescopic wheel assembly. When the telescopic wheel assembly is retracted, it is completely hidden in the wheel compartment 111, and the wheel compartment 111 is in contact with the ground, and the mobile silkworm platform cannot be pushed and remains in a stable state. When the telescopic wheel assembly is extended, the caster 300 partially or completely extends out of the wheel compartment 111, and the mobile silkworm platform can be easily pushed.

[0054] The telescopic wheel assembly includes a telescopic mechanism 200 and a caster 300. The telescopic mechanism 200 includes a top seat 210 and a base 220, wherein the top seat 210 is fixedly connected to the top of the wheel house 111, and the base 220 is connected to the caster 300. The telescopic mechanism 200 also includes a support arm, which is connected to the top seat 210 and the base 220 through a hinge point and can be telescopically controlled by a driving rod.

[0055] In one embodiment of the mobile silkworm platform of the utility model, the support arm includes a first folding arm 231, a second folding arm 232, a third folding arm 233 and a fourth folding arm 234, a top seat 210, a first folding arm 231, a second folding arm 232 and a base 220 are hinged in sequence, and a top seat 210, a third folding arm 233, a fourth folding arm 234 and a base 220 are hinged in sequence.

[0056] The driving rod is a screw rod 240 having a threaded section and an operating end. The threaded section of the screw rod 240 can pass through the through hole of the hinged part of the first folding arm 231 and the second folding arm 232, and be screwed with the nut 235 matched with the hinged part of the third folding arm 233 and the fourth folding arm 234. The operating end is detachably connected with a crank 250, and by turning the crank 250, the screw rod 240 can be controlled to rotate, thereby realizing the expansion and folding of the support arm.

[0057] When the telescopic mechanism 200 is retracted, the caster 300 is hidden in the wheel compartment 111. At this time, the bottom of the wheel compartment 111 is in direct contact with the ground, providing additional support and stability. When the silkworm platform needs to be moved, the telescopic mechanism 200 is extended by operating the crank 250, and the caster 300 is immediately extended from the wheel compartment 111 for easy movement.

[0058] The caster 300 is preferably a shock-absorbing universal wheel, which can move flexibly in multiple directions and has good buffering performance, thereby reducing the impact and noise on the ground during movement.

[0059] In one embodiment of the mobile silkworm platform of the present invention, the side wall of the wheel bin 111 is provided with an operating window 112, so that the operator can conveniently observe and operate the telescopic mechanism 200, thereby improving the convenience and efficiency of operation; at the same time, the operating window 112 can avoid structural interference between the side wall of the wheel bin 111 and the telescopic mechanism 200.

[0060] In one embodiment of the mobile silkworm platform of the utility model, the bottom of the wheel house 111 is provided with an anti-skid pad, which enhances the friction with the ground and ensures the stability of the silkworm platform under various ground conditions. One or more anti-skid pads are installed at the bottom of the wheel house 111. These anti-skid pads can be made of rubber, plastic or other materials with a good friction coefficient to ensure sufficient friction when in contact with the ground. The anti-skid pad can be fixed to the bottom of the wheel house 111 by bonding, snapping or bolting. The selected fixing method should ensure that the anti-skid pad is not easy to fall off during use, and is easy to replace and maintain. The shape and size of the anti-skid pad should match the bottom of the wheel house 111 to achieve the best contact area and anti-skid effect. The anti-skid pad can be designed to be fully covered or partially covered, depending on actual needs and design requirements. When the caster 300 of the telescopic wheel assembly is retracted into the wheel house 111, the anti-skid pad at the bottom of the wheel house 111 directly contacts the ground, providing additional support and stability. This is particularly important when the ground is uneven or slippery.

[0061] In one embodiment of the mobile silkworm platform of the utility model, the column 110 is a telescopic column. The length of these telescopic columns 110 can be adjusted by a built-in telescopic mechanism to adapt to different height requirements. Each telescopic column 110 includes at least two parts, which are connected by threads, snaps or other fastening methods. By rotating or operating the fasteners, the column 110 can be stretched or contracted to achieve height adjustment. The top of the telescopic column 110 is connected to the adjacent column through the top crossbeam 120, and the bottom is fixedly connected by the bottom crossbeam 130. The design of the top crossbeam 120 and the bottom crossbeam 130 should take into account the length change of the telescopic column 110 to ensure the stability of the structure.
