Description

[Detailed Description of the Invention] 1. The present invention relates to a dust cover used on a rotating shaft in automobiles, machine tools, construction machines, various industrial machines, and the like.

Conventionally, for example, when installing a dust cover for a drive shaft of an automobile, there has been one in which a cover body divided into two parts is adhesively bonded with an adhesive. There was no other way than removing the entire mechanism including the rotating shaft and then cutting and opening this cover. Further, there is a drawback in that the same complicated and troublesome work must be performed at the relevant place of other various machines.

Therefore, it is an object of the present invention to provide an epoch-making cover that eliminates such drawbacks.

2. Configuration of the Invention The configuration and operation of the present invention will be described with reference to the embodiments of the drawings.

First, the embodiment shown in FIGS. 1 to 3 will be described.

(1) is a flexible cover body that has an uneven shape as a whole,
The depth and height of the unevenness of the cover body are arbitrary. (2) is an opening in which the cover body (1) is spirally cut from the upper edge portion to the lower edge portion, and the collar portions (3) and (3) are provided on both left and right sides of the opening portion. It is provided so as to project. This opening
(2) The concave portion 4 is formed on the entire surface of one flange portion (3) or at an interval, and the convex portion (5) is provided on the entire surface of the other flange portion (3) facing the other or an interval. (6) is an elastic clip that is fitted on the outer surfaces of the left and right flanges (3) and (3) at appropriate intervals, and these elastic clips are fitted on the left and right flanges (3) and (3). This is effective when fixing the non-fitting part when the mating concave part (4) and convex part (5) are only partially provided, but the concave part and the convex part at the left and right flanges are effective. If it is used on the entire surface, the binding force becomes even stronger.

Thus, when the cover body is now attached to a predetermined place, the flange portions (3) projecting from the left and right sides of the opening (2) spirally formed in the cover body (1) having an uneven shape. After the concave portion (4) and the convex portion (5) facing each other in (3) are fitted and closed to be joined, an elastic clip (6) is hooked in place on the outer surface thereof.

Next, another embodiment of the present invention will be described with reference to FIGS.

(7) is a collar portion (3) protruding from both left and right sides of the opening (2) spirally cut from the upper edge of the cover body (1) to the lower edge.
The fastener body installed in (3) is for opening and closing the opening (2) of the cover body (1) by this fastener body.

Thus, when the cover body is attached at a predetermined position, the fastener body (7) on the opening line portion (2) provided in the spiral shape of the cover body (1) is closed and joined. .

3. Effect of the Invention The present invention thus has an opening (2) spirally cut at an appropriate angle from the upper edge to the lower edge of the flexible cover body (1) which is entirely uneven. It is characterized in that it is formed and coupled so that the spiral opening can be opened and closed. Therefore, a flexible cover body installed at a predetermined position of the rotary shaft of various machines including automobiles. The removal is done by opening the connecting parts on both left and right sides of the opening formed in a spiral shape along the vicinity of the peaks and valleys of the uneven surface diagonally downwardly and easily and quickly. After the joint work inside the cover body, repair of troubles, replenishment of grease, etc. are completed, a new cover body can be installed and installed again immediately. No flexibility or elasticity The airtightness can be sufficiently maintained without being lost, and the practical effect is great.

[Brief description of drawings]

The drawings show an embodiment of the present invention. Fig. 1 is a front view of a partly cutaway of the whole, Fig. 2 is a front cross-sectional view taken along line AA of Fig. 1, and Fig. 3 is Fig. 1A -A sectional view of the line A portion, Fig. 4 is a front view of a partial cutaway of another example according to another example, and Fig. 5 is a BB portion of Fig. 4.
FIG. 6 is a sectional view taken along the line BB of FIG. 4 in which the line portion is exploded.

Claims (3)

[Scope of utility model registration request] Claim: What is claimed is: 1. A flexible cover body having an uneven shape as a whole is formed with an opening portion spirally cut at an appropriate angle from the upper opening edge portion to the lower opening edge portion, and the spiral opening portion is opened and closed. A dust cover characterized in that it is connected so as to be opened and closed by means. 2. A flange is provided on both left and right sides of the spiral opening, a recess is provided on one of the flanges, and a projection is provided on the other of the flanges for connection. The dust cover according to claim (1), in which elastic clips are fitted on the outer surfaces of both of the flange portions. 3. A dust cover as set forth in claim 1, wherein a fastener is provided between the left and right sides of the spiral opening so as to be joined together.
