Abstract
Description
Technical Field
[0001] This utility model belongs to the field of foot cup technology, and in particular relates to an adjustable foot cup structure with an irregularly shaped knob. Background Technology
[0002] Trolley feet are adjustable support devices installed at the bottom of a trolley, providing stable support, height adjustment, shock absorption, and anti-slip functions. Through threaded rotation or a flexible base design, they allow the trolley to adapt to different ground conditions, ensuring stable equipment operation. For example, in logistics transportation, feet can adjust the trolley height to match loading and unloading platforms; in the medical field, shock-absorbing feet can reduce the impact of instrument vibration on accuracy.
[0003] However, existing foot cups rely solely on locking nuts to achieve height adjustment and locking functions. Locking nuts prevent loosening through friction, but in high-vibration environments (such as stamping equipment and vibrating screens) or under dynamic loads (such as cranes and automated production lines), the nuts are prone to loosening due to vibration, leading to equipment tilting, support failure, or even safety accidents.
[0004] The small threaded contact area between the locking nut and the adjusting rod makes it prone to thread wear and jamming due to localized stress concentration after long-term use. This manifests as increased adjustment resistance, unsmooth height adjustment, or even inability to adjust.
[0005] In addition, the existing locknuts require tools to adjust their height, making disassembly and adjustment inconvenient. Utility Model Content
[0006] The purpose of this utility model is to address the problems of existing foot cups in high-vibration environments, where the nut is prone to loosening due to vibration, leading to support failure, and the small contact area between the locking nut and the adjusting rod, resulting in localized stress concentration and increased adjustment resistance over long-term use. Furthermore, the locking nut requires tools for disassembly and adjustment, which is inconvenient. Therefore, this invention proposes an adjustable foot cup structure with an irregularly shaped knob.
[0007] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable foot cup structure with an irregularly shaped knob, comprising:
[0008] The threaded adjusting rod is connected to the support base.
[0009] And several irregularly shaped locking parts, which are adjustablely connected to the threaded adjusting rod, with the irregularly shaped locking parts located at the bottom abutting against the support base.
[0010] As a further description of the above technical solution:
[0011] The support base is provided with a limiting groove and a through hole, the limiting groove and the through hole are connected, the threaded adjusting rod is provided with a limiting head, the threaded adjusting rod passes through the through hole and is connected to the irregular locking part, and the limiting head abuts against the inner wall of the limiting groove.
[0012] As a further description of the above technical solution:
[0013] The limiting groove is polygonal, and the limiting head and the limiting groove are matched with each other.
[0014] As a further description of the above technical solution:
[0015] The polygon has at least four sides.
[0016] As a further description of the above technical solution:
[0017] The irregular locking component includes a locking nut and a knob body. The knob body is connected to the outer periphery of the locking nut, and the locking nut is screwed onto the threaded adjusting rod.
[0018] As a further description of the above technical solution:
[0019] The knob body and the locking nut are integrally formed.
[0020] As a further description of the above technical solution:
[0021] Multiple of the irregularly shaped locking elements are connected to the threaded adjusting rod in relative positions.
[0022] As a further description of the above technical solution:
[0023] The thickness of the irregular locking member located at the top is greater than the thickness of the irregular locking member located at the bottom.
[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0025] 1. In this utility model, by setting an irregularly shaped locking component, which includes a locking nut and a knob body, the knob body and the locking nut are an integral structure. This structure allows the height of the locking nut to be adjusted by rotating the knob body when adjusting the locking nut, making the adjustment convenient and highly practical.
[0026] 2. In this utility model, the thickness of the top irregular-shaped locking component is greater than that of the bottom irregular-shaped locking component. The top irregular-shaped locking component directly bears the weight of the equipment (vertical load), while the bottom irregular-shaped locking component mainly transmits the load to the ground. Increasing the thickness of the top irregular-shaped locking component can improve its compressive strength and prevent deformation or damage of the locking component due to long-term pressure. The bottom irregular-shaped locking component is thinner, which can reduce the overall weight and reduce costs while meeting the load transmission requirements.
[0027] 3. In this utility model, by thickening the top irregular locking part, the contact area between it and the adjusting rod is increased, which can disperse the local stress between the threads and reduce thread wear or jamming caused by load concentration; the bottom irregular locking part is thinner, which can reduce the frictional resistance with the adjusting rod and make height adjustment easier.
[0028] 4. In this utility model, by thickening the top irregular-shaped locking part, its connection strength is higher, which can resist the slight displacement caused by vibration and prevent the locking part from loosening. The bottom irregular-shaped locking part is thinner. The bottom irregular-shaped locking part, through the synergistic effect with the top irregular-shaped locking part, further enhances the anti-loosening performance. Attached Figure Description

[0044] And several irregularly shaped locking parts 3, which are adjustablely connected to the threaded adjusting rod 1, with the irregularly shaped locking parts 3 located at the bottom abutting against the support base 2.

[0046] The limiting groove 4 is polygonal, and the limiting head 6 and the limiting groove 4 are matched with each other.
[0047] The polygon has at least four sides. The limiting head is connected within the limiting groove to prevent rotation due to vibration, thus improving the stability of the connection.
[0048] The irregular locking component 3 includes a locking nut 31 and a knob body 32. The knob body 32 is connected to the outer periphery of the locking nut 31, and the locking nut 31 is screwed onto the threaded adjusting rod 1.
