Abstract
The invention provides a structure improved trundle body. The structure improved trundle body comprises a body and a straight shaft, a straight shaft hole allowing the straight shaft to penetrate is formed in the center of the body, a containing space is formed in the lower end of the straight shaft hole, and the straight shaft hole is communicated with the containing space. The straight shaft is inserted into the straight shaft hole of the body, a clamping stopper edge at the tail end of the straight shaft falls into the containing space of the body, the straight shaft is combined with the body, the upper edge face of the clamping stopper edge of the straight shaft can abut against the bottom edge of the straight shaft hole of the body, the straight shaft can be blocked by the bottom edge of the straight shaft hole and is not prone to falling or being damaged, and then the service life of a trundle can be prolonged.
Description
Technical field
The present invention about a kind of castor body of structural development, the more firm and castor body of difficult drop-off of espespecially a kind of combination making d-axis and body.
Background technology
General existing castor body 1, as shown in Figure 1, it is integrated ejection formation, in its center, there is d-axis groove 10, this d-axis groove 10 bottom place of fitting has ring flange 101, d-axis 2 is made to be arranged in the d-axis groove 10 of body 1, and the ring flange 101 of d-axis groove 10 is snapped in the circular groove 20 of d-axis 2, d-axis 2 is combined, so with body 1, the structure of this kind of body 1, the combination of itself and d-axis 2, the ring flange 101 by d-axis groove 10 snaps in the circular groove 20 of d-axis 2, and it is after permanent use, d-axis 2 very easily comes off, and causes castor to damage.
In prior art:
1: body;
10: d-axis groove;
101: ring flange;
2: d-axis;
20: circular groove;
In the present invention:
3: body;
30: d-axis hole;
31: accommodation space;
32: root edge;
4: d-axis;
40: braking edge;
401: upper limb face;
5: angle seat.
Summary of the invention
The invention provides a kind of castor body of structural development, make the combination of d-axis and body more firm and difficult drop-off.
The invention provides a kind of castor body of structural development, comprise body and d-axis, wherein d-axis bottom has a braking edge; Body is integrated ejection formation, and this body is combined with angle seat by d-axis, and this body central has the d-axis hole inserted 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, makes d-axis be subject to the root edge in d-axis hole stop and do not come off.
The advantage that the present invention has is:
After in the present invention, body is combined with d-axis, the braking edge of d-axis bottom is engaged and difficult drop-off by the root edge in body d-axis hole, therefore can extend the service life of castor.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the invention will be further described, can better understand the present invention and can be implemented, but illustrated embodiment is not as a limitation of the invention to make those skilled in the art.
The invention provides a kind of castor body of structural development, as shown in Fig. 2 ~ Fig. 5, it comprises body 3 and d-axis 4, and wherein d-axis 4 bottom has a braking edge 40; Body 3 is integrated ejection formation, and it is combined by d-axis 4 with angle seat 5, and have the d-axis hole 30 inserted for d-axis 4 in body 3 center, this lower end, d-axis hole 30 has an accommodation space 31, and this d-axis hole 30 and this accommodation space 31 are in communicating; D-axis 4 is made to be inserted in the d-axis hole 30 of body 3, and make the braking edge 40 of d-axis 4 end fall within the accommodation space 31 of body 3, then the upper limb face 401 of the braking edge 40 of d-axis 4 can be butted on the root edge 32 in the d-axis hole 30 of body 3, then d-axis 4 is combined with body 3, and d-axis 4 can stop and difficult drop-off by d-axis hole 30 root edge 32.
The above embodiment is only that protection scope of the present invention is not limited thereto in order to absolutely prove the preferred embodiment that the present invention lifts.The equivalent alternative or conversion that those skilled in the art do on basis of the present invention, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
