Abstract
The utility model discloses a trundle body of an improved structure. The trundle body comprises a body unit and a straight shaft. The center of the body unit is provided with a straight shaft hole for the straight shaft to place in, an accommodation space is formed in the lower end of the straight shaft hole, and the straight shaft hole is communicated with the accommodation space. The straight shaft is inserted in the straight shaft hole of the body unit, a clamping edge at the tail end of the straight shaft is made to be in the accommodation space of the body unit, and the straight shaft is made to be combined with the body unit, so that the upper edge face of the straight shaft clamping edge can abut against the bottom edge of the straight shaft hole of the body unit. The straight shaft can be blocked by the bottom edge of the straight shaft hole and can not easily disengage and be damaged, and therefore the service life of a trundle is prolonged.
Description
Technical field
The utility model is about a kind of castor body of structural development, espespecially a kind of castor body in conjunction with more firm and difficult drop-off that makes d-axis and body.
Background technology
General existing castor body 1, as shown in Figure 1, it is integrated ejection formation, the Yu Qi center has d-axis groove 10, suitable place, these d-axis groove 10 bottoms has ring flange 101, d-axis 2 is arranged in the d-axis groove 10 of body 1, and the ring flange 101 that makes d-axis groove 10 snaps in the circular groove 20 of d-axis 2, make d-axis 2 and body 1 combination, so, the structure of this kind of body 1, the combination of itself and d-axis 2, snap in the circular groove 20 of d-axis 2 by the ring flange 101 of d-axis groove 10, it is after permanent the use, d-axis 2 very easily comes off, and causes castor to damage.
The utility model content
The utility model provides a kind of castor body of structural development, make d-axis and body in conjunction with more firm and difficult drop-off.
The utility model provides a kind of castor body of structural development, comprises body and d-axis, and wherein the d-axis bottom has a braking edge; Body is integrated ejection formation, and this body is combined with the angle seat by d-axis, and this body center has the d-axis hole of inserting for d-axis, and this lower end, d-axis hole has an accommodation space, and this d-axis hole communicates with this accommodation space; This d-axis is inserted in the d-axis hole of body, and makes the braking edge of d-axis end fall within the accommodation space of body, and this braking edge is limited in this accommodation space.
Further, the upper limb face of the braking edge of this d-axis is butted on the root edge in body d-axis hole.
The advantage the utlity model has is:
In the utility model, body is after d-axis is combined, and the braking edge of d-axis bottom is locked and difficult drop-off by the root edge in body d-axis hole, therefore can extend the service life of castor.
