Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint for connecting the ends of filaments such as wires or ropes to each other, and a stone removing belt for a double tire using the joint.

[0002]

2. Description of the Related Art Large trucks such as dump trucks
Since the cargo bed is supported by the front and rear double tires, stones are easily caught between the double tires, and it is extremely dangerous to send it as it is, as a preventive measure between the front and rear double tires. The stone removing belt is hung over the belt. By the way, the conventional stone removing belt is generally used by connecting it in an annular shape by using a V belt for transmitting the rotational movement of the machine. Further, the one disclosed in Japanese Utility Model Laid-Open No. 2-41859 is also known, and the stone removing band is formed by caulking both ends of the wire by connecting pipes and connecting them, and covering the outer periphery thereof with an elastic member.

[0003]

Since the above-mentioned conventional one is formed in an annular shape, when it is mounted between the front and rear double tires, the tire of the dump truck is lifted by supporting the body of the dump truck with the jackie. Raise and remove only one of the front and rear outer tires, then hang one of the annular stone bands between the double tires on the side where it has not been removed, and hang the other stone band on the side from which the tire was removed. However, at that time, if the tire that has been simply hung and removed as it is is attached to the original state, the stone removing belt will be caught between the wheels of the inner and outer tires and the stone removing function will not be obtained. Therefore, in the past, when reattaching the removed tire, pull the edge of the stone removing belt so that the curve of the edge of the stone removing belt does not touch the wheel, and keep that state. It is to install tires.

As described above, the above-mentioned work for attaching requires pretreatment such as jacking up and post-treatment such as attaching tires again. Therefore, it takes time to attach the stone removing belt. Not only that, but in many cases it is entrusted to specialists such as tire replacement shops and automobile repair shops. Especially when using the above-mentioned V-belt, the wear is fast and it is necessary to replace it in one or two months. There was a need for something that would be more durable and easier to install.

In view of the above problems, the present invention has been devised so that one line can be attached to both front and rear double tires, and both ends can be connected by a simple operation. Basically, it is connected by bayonet connection so that they are connected in a straight line without making a difference,
The joint must be fixed so that the cleat can be cleverly eliminated and both ends can be connected by a simple operation, and that once joined, it will not come off due to pulling force or vibration, and that the joined state will be held securely. The idea is to provide a robust stone removing belt by utilizing the joint.

[0006]

Means for Solving the Problems The solution according to the present invention comprises a male and female socket made of a tubular body, the female socket having a groove on the inner peripheral surface of the tubular body along the axial direction from the opening edge thereof. The male socket is provided with a locking groove which is continuous with the concave groove and extends in the circumferential direction. The male socket is provided with a connecting rod projecting from its open end, and the male socket is inserted into the concave groove of the female socket at the tip of the connecting rod. At the same time, by providing a convex portion that fits into the locking groove by rotating either the male or female socket, a concave portion is formed on the surface facing the concave groove by the rotation of the male or female socket at the tip of the connecting rod. A wedge piece fitted in the groove can be slid in the axial direction,
Moreover, it is characterized in that it is urged toward the tip end of the connecting rod by a spring.

Further, in the stone removing belt using the joint, the female socket is fixed to one end of the wire, the male socket is fixed to the other end of the wire, and the outer circumference of the wire and the male and female sockets can be covered. It is characterized in that it is covered with an elastic covering tube.

[0008]

[Function] When connecting the male and female sockets, the convex portion of the male socket is inserted into the concave groove of the female socket. At that time, the wedge piece of the male socket abuts against the end face of the female socket, but the convex portion is deep in the concave groove. By inserting and rotating the male socket or female socket there, the convex portion fits into the locking groove of the female socket, and at the same time, the wedge piece faces the concave groove and is biased by the spring. Is retained in the concave groove, prevents mutual rotation of the male and female sockets, and is retained in the engaged groove in the convex portion so as to be inseparable from each other.

Further, in order to attach the stone removing belt using the above joint between the front and rear double tires, the front and rear double tires are not supported by the jacky and are supported by the tires. The stone removing band is hung over the both ends, and both male and female sockets provided at both ends thereof are butt-joined to each other in the same manner as described above to form an annular shape. Only the wire circulates, the combined male and female sockets are inserted and hidden in the elastic cladding tube, and since the joint has a larger diameter than the wire after that, the wire also circulates with the elastic cladding tube to prevent stone entrapment. To do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The joint of the present invention will be described in detail. As shown in FIGS.
Each of the male and female cylindrical bodies 3 and 4 which are formed by the male and female sockets 2 and constitute the male and female sockets 1 and 2 has one mouth wide and the other narrowed down, and each end 5 of the wire 5 is narrowed from the narrow mouth.
A and 5b are inserted, and flange-shaped stoppers 6 and 7 are welded to the respective end portions 5a and 5b so as not to come out. Both wide mouths are formed to have the same size.

The female socket 1 is provided with a pair of recessed grooves 8 and 8 along the axial direction of the cylinder with a phase of 180 ° from the edge of the wide mouth, and the recesses 8 and 8 are continuous to the inner portions of the recessed grooves 8 and 8. Locking groove 9,
9 are provided along the circumferential direction, so that the concave groove 8 and the locking groove 9 are L-shaped when viewed two-dimensionally. However, as shown in the figure, the locking groove 9 is formed over the entire circumference.

On the other hand, in the male socket 2, a connecting rod 10 is projectingly provided on a stopper 7 fixed to the wire 5 with a length projecting from its wide mouth, and at the tip of the connecting rod 10, inside the concave grooves 8 and 8 of the female socket 1. Is provided with convex portions 11 and 11 to be inserted into
In addition, by rotating either one of the male and female sockets 1 and 2, the convex portion 11 inserted into the concave groove 8 is formed so as to be inserted into the locking groove 9. Further, a long hole 12 which is long in the axial direction is formed at the tip of the connecting rod 10, and the both convex portions 1
1, 11 are penetrated in a direction orthogonal to the projecting direction, and a support piece 13 is slidably inserted in the elongated hole 12 in the longitudinal direction. The wedge pieces 14 and 14 (see FIG. 4) that project into the inside 8 are fixed, and the wedge pieces 14 and 14 are fixed by the spring 15 fitted to the connecting rod 10.
Is urged toward the tip of the connecting rod 10. By the way, the spring 15 of each wedge piece 14 and 14 described above.
As shown in FIG. 5, a ring 16 that abuts on the spring 15 may be fixed over both rear end portions of the wedge pieces 14, 14 so that the biasing force of the wedge is strong and reliable. preferable.

It should be noted that the number of the recessed grooves 8 is sufficient if the number of the recessed grooves 8 is two, but the number of the recessed grooves 8 is not limited to this, and a plurality of recessed grooves 8 may be provided, while the engaging groove 9 and the convex portion 11 are provided. The wedge pieces 14 may be provided in the same number as the concave grooves 8.

Because of the above-mentioned structure, when connecting them, both the convex portions 11, 11 are inserted into the concave grooves 8, 8 so as to face the concave grooves 8, 8 as they are. When facing the recessed groove 8, as shown in FIG.
The tip end of the wedge contacts the end face of the female socket 1, and the wedge piece 14 moves backward against the biasing direction of the spring 15 as the projection 11 is sequentially inserted deep into the groove 8. To do. Next, by rotating (rotating 90 °) either one of the male and female sockets 1 and 2,
At the same time that the wedge pieces 14 and 14 are moved into the locking groove 9, the wedge pieces 14 and 14 face the concave grooves 8 and 8, and are pushed into the concave grooves 8 and 8 by the repulsive force of the spring 15, and the state is maintained. Therefore, the male and female sockets 1 and 2 are connected in a state in which the rotation is blocked. Therefore, the operation of coupling is such that the male and female sockets 1 and 2 are butted against each other with the convex portion 11 at the top, and only one of them is rotated thereafter, making it impossible to separate the male and female sockets 1 and 2 as shown in FIG. Is to be combined.

Next, in the structure of the stone removing belt for a double tire using the above-mentioned joint, as shown in FIGS. 7 and 8, the wire 5 is inserted into the elastic covering pipe 17, and one end of the wire is inserted. The female socket 1 is attached to 5a, and the male socket 2 is provided to the other end 5b. The elastic sheath 17 is specifically a hose used for an air compressor (outer diameter 25 mm, inner diameter 15 mm). To use. The wire 5 has a diameter of 7 to 8 mm, and the length thereof is substantially the same as that of the elastic covering tube 17. Therefore, the heads of the male and female sockets 1 and 2 attached to the wire 5 project from the ends of the elastic coating tube 17.

In order to mount the above-mentioned stone removing belt between the front and rear double tires, the stone removing belt is hung between the front and rear inner and outer tires from above or below, and both male and female sockets 1 and 2 are provided at both ends. It is possible to straddle it in a ring at once by putting together and connecting the male and female sockets 1 and 2 exposed between both ends of the elastic covering pipe 17 at the beginning when the stone removing belt is hung. However, when the vehicle is driven, only the elastic covering pipe 17 rotates together with the tire due to friction with the tire, the male and female sockets 1 and 2 are inserted and hidden in the elastic covering pipe 17, and thereafter compressed by the inner and outer tires. Therefore, since the male and female sockets 1 and 2 rotate integrally with the elastic coating pipe 17, the male and female sockets 1 and 2 are not exposed, and the state is kept to prevent stones from being caught between the double tires. It is to prevent.

[0017]

According to the linear joint of the present invention, by inserting the convex portion of the male socket into the concave groove of the female socket and rotating either one of the male and female sockets as it is, the wedge piece of the male socket becomes the spring. Since it is automatically inserted into the groove by the repulsive force, the connecting operation is extremely simple, and since the wedge piece is biased by the spring and inserted into the groove, vibration is applied. Also, even if a strong pulling force is applied, the male and female sockets do not separate, and the state where they are securely connected is maintained.

In the case of a double tire stone removing belt using the above-mentioned linear joint, it is not necessary to detach the tires one by one, and it is immediately hung between the front and rear double tires, and both male and female sockets are joined to form a ring at once. You can
The mounting operation is easy, and since both male and female sockets can be connected along a straight line, there is no fear of scratching the tire and it can be used for a long time without coming off during use. .
