Description

Improvement of the movable wheel structure of the telescopic cover (1)

The movable wheel structure improvement of the creation telescopic cover (1) is mainly applied to the technology of the movable wheel of the telescopic cover, and has the characteristics of wear resistance and not easy to fall off.

The applicant of the case was previously approved by the bureau, and the announcement number is 540439, "The improvement of the sliding wheel structure of the telescopic cover" is a new type of patent, which mainly consists of a U-shaped gap that can accommodate the sliding wheel at the bottom of the fixing piece, and is in the shape of a U-shaped A shaft hole is drilled on each side of the notch to pivot the sliding wheel through the shaft hole of the U-shaped notch. The U-shaped notched side of the fixing piece is vertically extended downward with a circular arc-shaped sliding edge, so that the sliding wheel and the circular arc-shaped sliding edge can slide on a mechanical linear sliding rail or a hard rail such as a comprehensive cutting machine or a grinder. By.

However, the above-mentioned "pre-extension of the sliding wheel structure improvement of the telescopic cover" can reduce the frictional resistance between the telescopic cover and the linear slide rail or the hard rail and increase the sliding effect of the telescopic cover in practical application, but at least still There are two problems and gaps that exist that need to be overcome.

1. The outer diameter of the sliding wheel is smaller than the accommodating space, so that the sliding wheel is easy to wear and must be frequently replaced.

Second, the sliding wheel is only pivoted into the shaft hole by the shaft, so that the sliding wheel is easy to fall off and must be repaired frequently.

The creator is currently engaged in the manufacture and design of related products, and has accumulated many years of practical experience and experience. In response to the existing problems and shortcomings of the above-mentioned new patents for the "sliding wheel structure improvement of telescopic coverage", the enthusiasm actively participates in the spirit of innovation and improvement. The structure of the movable wheel of the completed telescopic cover is improved (1).

The technical means applied by the new problem solving and the effect of the prior art are as follows: the top side and the side of the fixed wheel base are provided with a horizontally engaging groove and a longitudinally embedded groove, and the bottom of the fixed wheel base is provided with an accommodation. The space, the two side walls of the accommodating space are provided with corresponding two lateral pivot holes, and a transverse shaft can be pivoted to form a movable wheel. The center of the movable wheel is provided with a shaft hole as a transverse shaft. For pivoting, the outer diameter of the movable wheel is larger than the accommodating space, so that the movable wheel has wear-resisting characteristics, and the fixed wheel base is provided with a longitudinal pivot hole for the longitudinal shaft to pass through a bearing and a bearing The spacer, the transverse shaft and the longitudinal shaft are integrated into the lateral pivot hole and the longitudinal pivot hole of the fixed wheel base by means of injection molding, and the fixing effect is good and the falling is not easy to fall off, and the utility model has the advantages of improving the efficiency. The winner.

In order to make it easier for those who are familiar with the art to understand the structure of the creation and the functional benefits that can be achieved, a specific embodiment will be listed, and the details will be described as follows: a movement of the telescopic cover Wheel structure improvement (1), please refer to the first and second figures: the schematic combination of the front view and the bottom view. And the third figure shows: a three-dimensional decomposition diagram of the creation. And the fourth picture shows: a schematic diagram of the cross-section of the creation. The main purpose is that the top side and the side of the fixed wheel base 10 are provided with a transverse insertion groove 11 and a longitudinal insertion groove 12, and the fixed wheel base 10 corresponds to a corner of the horizontal insertion groove 11 and the longitudinal insertion groove 12. An accommodating groove 13 is disposed at the bottom of the fixing wheel base 10. The two side walls of the accommodating space 14 are provided with corresponding two lateral pivot holes 15, 16 for a transverse axis. The rod 20 is pivoted and coupled with a movable wheel 30. The fixed wheel base 10 is integrated with the transverse shaft 20 during injection molding. The center of the movable wheel 30 is provided with a shaft hole 31 as a transverse shaft 20 For example, the outer diameter of the movable wheel 30 is larger than the accommodating space 14 so that the movable wheel 30 can be exposed outside the accommodating space 14 and has wear resistance characteristics; the fixed wheel base 10 is perpendicular to the horizontal pivot hole. A longitudinal pivot hole 17 is provided at a portion 16 for pivoting a longitudinal shaft 40 to a bearing 50 and a spacer 60. The longitudinal shaft 40 is provided with a smaller outer diameter rod 41, and the longitudinal shaft 40 An outer step 42 is provided between the rod body 41 and the fixed wheel base 10 is combined with the longitudinal shaft 40 for injection molding. As one.

The combination of the above-mentioned various component structures is based on the improvement of the movable wheel structure of the telescopic cover (1), in practical application: please refer to the fifth figure: Use state and partial enlargement diagram. As shown in the sixth figure, it is a schematic diagram of the side view state of the creation. The telescopic cover 70 can be elongated and shortened along with the path of the machining stroke, and is used as a guide rail 80 for protecting the processing machine. The telescopic cover 70 is provided with a plurality of fixing pieces 71 arranged from a short to a long shape at a plurality of ㄇ-shaped openings inside the plurality of ㄇ-shaped covers, and the plurality of fixing pieces 71 are arranged neatly above the guide rail 80. The telescopic cover 70 can prevent the cutting chips or other foreign matter generated during processing from falling on the guide rail 80, thereby affecting the precision of the processing.

The movable wheel structure improvement (1) of the telescopic cover provided by the present invention is mainly for the purpose of making the telescopic cover 70 slide more smoothly on the guide rail 80, and particularly, the fixed wheel base 10 is mounted on both sides of the fixed piece 71. At the corner, the width of the lateral insertion groove 11 and the longitudinal insertion groove 12 of the fixed wheel base 10 is slightly smaller than the thickness of the fixing piece 71, so that the fixed wheel base 10 can be embedded and fixed to the telescopic cover 70 in a slightly tight manner. The fixing piece 71 allows the movable wheel 30 and the bearing 50 to slide at the top and side faces of the guide rail 80. At the same time, it has the following two features:

1. The outer diameter of the movable wheel 30 is larger than the accommodating space 14, so it has the characteristics of wear resistance.

2. The lateral shaft 20 and the longitudinal shaft 40 are coupled to the lateral pivot hole 16 and the longitudinal pivot hole 17 of the fixed wheel base 10 by means of injection molding. It has a good fixing effect and is not easy to fall off.

In summary, the creation of the movable wheel structure (1) that provides a telescopic cover is confirmed by the creator's actual production and repeated operation tests, and it is confirmed that the functional benefits expected by the creation can be achieved. It is also the first creation that has not yet been seen in the market. It has the industrial use value. It has already met the important requirements of the practicability and progress of the new patent, and has filed a new patent application with the bureau in accordance with the provisions of the Patent Law.
