Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0020] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "fixation", and "connection" should be understood in a broad sense.

[0022] In the description of this embodiment, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation on the protection scope of this application.

[0023] In addition, the terms "first", "second", etc. are only used for distinction in description and have no special meaning.

[0024] The pin-type foot pad of this embodiment can be installed on the plates of the chassis and the casing, and is used to support and protect the chassis and the casing. The plate is provided with installation holes for installing the pin-type foot pad.

[0025] Combined with Figures 1 to 3As shown in the figure, the plug-in foot pad of this embodiment includes a main body 1 and a pin 2 that are detachably connected. Among them, the main body 1 includes a support portion 11 and a plurality of clamping portions 12 connected to the top end of the support portion 11; the clamping portions 12 are used to penetrate into the mounting holes of the plate and be clamped (or interference-connected) with the mounting holes of the plate, so that the main body 1 can be firmly connected to the plate without falling; the support portion 11 is used to support the chassis from the bottom of the plate. The support portion 11 of the main body 1 is generally in the shape of a frustum of a cone with a larger top and a smaller bottom. A through hole for interference fit with the pin 2 is provided in the support portion 11, and the axis of the through hole coincides with the axis of the support portion 11. The plurality of clamping portions 12 are arranged at intervals of two along the circumference of the through hole (in other words, there is no connection between any two clamping portions 12), and the plurality of clamping portions 12 together form a receiving cavity 121 for the pin 2 to penetrate into. At least a part of each clamping portion 12 covers the through hole, or in other words, at least a part of each clamping portion 12 hangs above the through hole, so that the space of the receiving cavity 121 is smaller than the space of the through hole. Thus, when the pin 2 penetrates into the through hole from the bottom end of the support portion 11 and then into the receiving cavity 121, the plurality of clamping portions 12 are extruded and deformed outward to be clamped with the mounting holes of the plate, realizing the fixation of the plug-in foot pad on the plate.

[0026] With the above structure, the plug-in foot pad of this embodiment has the advantages of simple installation, repeatable disassembly and assembly, and firm and reliable connection.

[0027] As Figure 3 shown, the pin 2 of this embodiment includes a head 21 and a rod portion 22 that are connected. Correspondingly, as Figure 1 shown, the through hole in the support portion 11 is a countersunk hole, and the countersunk hole includes a large-diameter section 111 and a small-diameter section 112 that are connected. The diameter of the large-diameter section 111 is greater than the diameter of the small-diameter section 112. The large-diameter section 111 is used to accommodate the head 21 of the pin 2, and the small-diameter section 112 is used to accommodate the rod portion 22 of the pin 2. With the above solution, the countersunk hole can play a role in limiting the pin 2 during the insertion of the pin 2. Further, the depth of the large-diameter section 111 is greater than the thickness of the head 21 of the pin 2 to prevent the head 21 of the pin 2 from being exposed outside, thus affecting the smoothness of the contact between the foot pad main body 1 and the ground; the depth of the small-diameter section 112 is less than the length of the rod portion 22 of the pin 2 to ensure that the rod portion 22 of the pin 2 can penetrate through the small-diameter section 112 of the countersunk hole and then into the receiving cavity 121 formed by the plurality of clamping portions 12. Preferably, the diameter of the large-diameter section 111 is 1-2 mm greater than the diameter of the head 21 of the pin 2 for easy disassembly of the pin 2.

[0028] As Figure 1 and Figure 2 shown, the support portion 11 of this embodiment is also provided with a plurality of material-reducing cavities 113, and the plurality of material-reducing cavities 113 are evenly distributed along the circumference of the through hole, which is beneficial to saving material costs.

[0029] As shown Figure 1 in the figure, an anti-slip structure is further provided at the bottom end of the supporting portion 11 of this embodiment. Further, as shown Figure 4 in the figure, the anti-slip structure of this embodiment may be a plurality of concentric annular grooves 114. The anti-slip structure can increase the friction between the supporting portion 11 and the ground and improve the anti-slip ability of the foot mat.

[0030] The foot mat main body 1 of this embodiment can be made of thermoplastic elastomer (abbreviated as TPE), and the pin 2 can be made of nylon.

[0031] In summary, the usage method of the plug-in foot mat of this embodiment is as follows: A person or a machine grasps the supporting portion 11 of the main body 1, inserts the clamping portion 12 of the main body 1 into the installation hole of the plate, and then inserts the pin 2 into the counterbore of the supporting portion 11 until the pin 2 can no longer move in the axial direction, indicating that the pin 2 is installed in place. At this time, the plurality of clamping portions 12 are extruded and deformed outward by the rod portion 22 of the pin 2, so as to interfere with the plate, and further the main body 1 cannot move axially; when the foot mat needs to be disassembled, only need to pull out the pin 2 from the counterbore. After the extrusion force received by the clamping portion 12 disappears, it no longer interferes with the plate too much, and then it can be withdrawn from the installation hole.

[0032] In the present utility model, specific embodiments are used to elaborate the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
