Abstract
The utility model relates to a kind of castor connection structure, comprise castor, lay the support of castor, be located at anchor shaft on support and axle sleeve fixed mount, the sheathed elastic soft cover of described anchor shaft, the anchor shaft being arranged with elastic soft cover is fixedly connected with an axle sleeve through the through hole of axle sleeve fixed mount.This castor connection structure is easy to install, and repeatedly can plug, and can improve finished product rate.
Description
Technical field
The utility model relates to a kind of castor connection structure, particularly relates to the castor on a kind of household equipment or articles for use kind equipment.
Background technology
At present, often there is the situation needing shift position in home-use large electric appliances, furniture or articles for use in routine use, but cause more greatly mobile inconvenient due to the volume and weight of object own, usually adopts the method for installing castor to solve the problem.But traditional castor fixed form generally adopts forces the mode of interference to load inside fixed hole position by truckle connecting device, Problems existing is that castor installation difficulty is large, likely cause distortion and damage Castor structure, and not quick detachable after installing, also there is the large problem of the inaccurate noise in location.
Utility model content
The utility model embodiment technical matters to be solved is: provide a kind of castor connection structure, can realize the dismounting of castor more fast, more easily.
In order to solve the problems of the technologies described above, the utility model embodiment proposes a kind of castor connection structure, comprise castor, lay the support of castor, be located at anchor shaft on support and axle sleeve fixed mount, the sheathed elastic soft cover of described anchor shaft, the anchor shaft being arranged with elastic soft cover is fixedly connected with an axle sleeve through the through hole of axle sleeve fixed mount.
Further, the axis body of described anchor shaft is provided with at least one annular groove, and described elastic soft cover is sheathed in described annular groove.
Further, the inwall of described elastic soft cover or outer wall are provided with at least more than one bulge loop or strip convex tendon.
Further, the inwall of described elastic soft cover, outer wall are respectively equipped with negative thread and outside thread.
Further, negative thread is provided with in the through hole of described axle sleeve.
Further, at least more than one bulge loop or strip convex tendon is provided with in the through hole of described axle sleeve.
Further, the anchor shaft axis body on described support is provided with outside thread.
Further, the anchor shaft axis body on described support is provided with at least more than one bulge loop or strip convex tendon.
Further, the anchor shaft front end on described support is provided with limiting section, and described limiting section outer rim has a tapered guide surface.
Further, described elastic soft cover is made for silica gel, rubber or EVA elastomeric material.
The castor connection structure of the utility model embodiment has following beneficial effect: when assembling castor, elasticity ring set generation elastic deformation, make to realize interference fit between anchor shaft and axle sleeve, so reach for convenience detach, simultaneously due to elastic deformation, force interference fit to cause connection structure to be damaged when avoiding installation, improve yield rate.
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the first embodiment confined state cutaway view of the utility model castor connection structure;
Fig. 2 is the enlarged drawing of part A in Fig. 1;
Fig. 3 is the utility model castor connection structure the second embodiment cutaway view;
Fig. 4 is the third embodiment cutaway view of the utility model castor connection structure.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail:
The first embodiment assembling schematic diagram of the utility model castor connection structure as shown in Figure 1 and Figure 2, comprise castor 10, lay the support 11 of castor, be located at anchor shaft 12 on support and axle sleeve fixed mount 20, the sheathed elastic soft cover 30 of anchor shaft 12, the through hole 21 that the anchor shaft 12 being arranged with elastic soft cover 30 passes axle sleeve fixed mount 20 is fixedly connected with an axle sleeve 40, the external diameter of elastic soft cover 30 is wherein greater than the internal diameter size of axle sleeve 40, utilizes the elastic deformation of elastic soft cover 30 and axle sleeve 40 to carry out interference fit.
In order to prevent elastic soft cover 30 sheathed on anchor shaft 12 from producing displacement, be preferred embodiment arrange annular groove 13 on anchor shaft 12, elastic soft cover 30 is socketed in annular groove 13.
For saving material, reducing costs, can design the annular groove 13 of more than two, as shown in Figure 4, two annular grooves 13 are arranged at the position close to head end and tail end of anchor shaft 12 respectively, and two corresponding elastic softs overlap 30 and are socketed in annular groove 13.
In order to increase the friction force between elastic soft cover 30 and axle sleeve 40, can be optimized the surface texture of elastic soft cover, as shown in Figure 3, elastic soft cover 30 preferred distressed structures are for be provided with at least one bulge loop 31 or strip convex tendon at its outside face, and bulge loop or convex tendon can be set to perpendicular to the axis direction of anchor shaft or level in the axis direction of anchor shaft.Accordingly, be placed on friction force between anchor shaft to increase elastic soft, bulge loop or strip convex tendon also can be arranged on the inside face of elastic soft cover.
In order to increase friction force, also can be optimized the surfaces externally and internally of axle sleeve through hole, preferably, at least one bulge loop or convex tendon can be set at the surfaces externally and internally of axle sleeve through hole; Another preferred mode is for be provided with negative thread at axle sleeve through hole.
During in order to assemble, anchor shaft can quicker, easierly extend in axle sleeve through hole, can arrange the spigot surface 14 of taper at the head end of anchor shaft.
The material of above-mentioned elastic soft cover can be the flexible materials such as silica gel, rubber, EVA.
During assembling castor, first castor 10 and support 11 are assembled, again elastic soft cover 30 is socketed in annular groove 13 place of anchor shaft 12, afterwards axle sleeve 40 is fixed on the installation position of fabricated section (not shown) by axle sleeve fixed mount 20, then anchor shaft 12 is clamp-oned in the through hole 41 of axle sleeve 40 together with elastic soft cover 30, allow elastic soft overlap between 30 and axle sleeve 40 and form interference fit, be seated.
The above only further illustrates technology contents of the present utility model with embodiment; so that reader is easier to understand; but do not represent embodiment of the present utility model and be only limitted to this, any technology done according to the utility model extends or recreation, all by protection of the present utility model.
