Description

EARLESS BAND CLAMP < RTI ID = 0.0 >

The present invention relates to a band clamp, and more particularly, to a clamp for maintaining the airtightness of a connection part while firmly connecting the connection tube and the pipe by pressing the surface of connection parts of various pipes such as a CV joint, Band.

The clamp band is used to tightly fasten a rubber or plastic cover that covers the joint member at a universal joint or constant velocity joint of the vehicle.

Conventional clamp bands are band-shaped stainless steel materials banded in a circular shape. In the clamp band, there is an ear-free type band in which a band is joined while a band is tightened at a position where the band is to be bound. This band is very convenient because there is no ear, there is almost no protruding part, and the band can be bound only by the binding hole and the protruding type binding means coupled thereto.

On the other hand, the buckles surrounding both ends of the clamp band as known in 10-2016-0064195A have holes in the outer side spaced apart from the object to be fastened in order to accommodate the punch portions which deform the clamp band ends and lock them together.

10-2016-0064195A (June 06, 2016)

The technical object of the present invention is to strengthen the fastening of the clamp band and to prevent the clamp band from being twisted or shifted to one side and not functioning normally.

According to an aspect of the present invention, the earless clamp band includes an arm tunnel portion provided at an end of the auxiliary binding hole, a male tunnel portion projecting upwardly in close contact with the arm tunnel portion, A tongue portion having a concave center in the shape of "U" or "V", and a channel portion provided between the arm tunnel portion and the hooking protrusion portion and closely contacting the tongue in a shape corresponding to the tongue portion, In the assembled state in which the clamp band is primarily bonded in the " O " shape before the clamp band is coupled to the connection tube body, the gummy-ring-annular protrusion is engaged with the end of the assisting fastening hole and is supported so that the clamp band is no longer extended , The male tunnel portion is coupled to the auxiliary binding hole, and when the clamp band is assembled by tightening the clamp band in the direction of decreasing the diameter, The lip ring-shaped protrusion supports the clamping band so that the clamping band is no longer extended to the end of the auxiliary binding hole by replacing the position of the auxiliary wedge-shaped annular protrusion, and the main protrusion is coupled to the main binding hole, And the tunnel part and the water tunnel part come into close contact with each other to support the clamp band so that the clamp band is not tightened any more.

According to the present invention, the airtightness is maintained more and more before and after the clamping band is clamped, and the guideline is maintained so that the band does not come off or twist after the clamping.

The objects, features and advantages of the present invention will become more apparent from the following detailed description. In the following description of the present invention, a detailed description of known technologies related to the present invention will be omitted when it is determined that the gist of the present invention may be unnecessarily blurred. Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a preferred embodiment of the earless clamp band according to the present invention.

Fig. 2 is a view showing an example in which the clamp band according to the present invention is coupled to a connecting pipe (e.g., a CV joint).

Referring to FIG. 2, in a state where the both ends of the clamp band 100 are overlapped with the connecting portion of the tube coupled to the connection tube 200, the band is tightened with a bare hand or a separate tool in the direction of decreasing the diameter The protrusions and the hooks are engaged to couple the bands, and the clamp band 100 presses the surface of the connection tube 200.

1, the earless clamp band 100 includes a hook portion 110, a hook protrusion 120, an arm tunnel portion 130, a male tunnel portion 140, a tongue portion 150, and a channel portion 160 ). The hooking protrusion 120 is coupled to the hook 110 to bend one end of the band outward to be coupled with the outer plate so as to cover a part of the outer plate, thereby hooking and fixing in the form of a ring.

The hook portion 110 includes a main binding hole 112, which is a rectangular groove, and an auxiliary binding hole 114, which is long in a longitudinal direction, so that the annular protrusion is bound. The auxiliary binding hole 114 is a long slot in the longitudinal direction to serve as a guiding line for moving the hooking protrusion 120 or the male tunnel 140 in the process of assembling and assembling the hooking protrusion 120, Or the male tunnel part 140 is detached to guide the band so that it is not tilted to the left or right.

The hooking protrusion 120 includes a gossiping annular protrusion 122 and an assembling protrusion 124, 126. The gob-shaped annular protrusion 122 has a bent portion and protrudes above the outer plate of the band. In the assembled state, a claw-like annular protrusion is bound to the auxiliary binding hole 114 to support the clamp band 100 so that it is no longer extended.

FIG. 3 is a view showing the engagement of the gummy-loop annular protrusions 122 in the process of being assembled from the gapped-up state. The earless clamp band 100 is transported in an assembled state having a band primarily in an " O " shape before coupling the clamp band 100 to a CV joint or the like, and when the assembled band is in the engaged position, Tighten by applying external pressure in the decreasing direction (fastening state).

Referring to FIG. 3, in the assembled state (S310), the repellent annular protrusion 122 is engaged with the end of the auxiliary binding hole 114 and is held so that the band 100 is no longer extended. When the band is tightened and assembled (S320), the assembling protrusion 124 replaces the assembling protrusion 124 instead of the assembling protrusion 122, and the protrusion 124 is caught by the auxiliary binding hole 114, (114).

The assembling protrusions 124 and 126 are protrusions protruded upward so as to be coupled to the hooks 110 and protrude in a direction parallel to the ground surface. .

Referring to FIG. 3 again, when the assembly state (S320) is reached in the assembled state (S310), the auxiliary protrusion 124 is temporarily bound to the main binding hole 112 and then moved to the auxiliary binding hole 114, So that the band is no longer extended by the end of the hole 114, and the main protrusion 126 is engaged with the main binding hole 114 as it is assembled.

The arm tunnel part 130 is provided at an end of the auxiliary binding hole 114 and protrudes upward and has an inner hollow dome shape and the male tunnel part 140 is upwardly protruded toward the arm tunnel part 130 And is in the form of protruding projections.

FIG. 4 is a view showing a connection between a dark tunnel part and a water tunnel part according to the present invention; FIG.

4, the male tunnel part 140 is coupled to the auxiliary coupling hole 114 in the assembled state S410, and the male tunnel part 140 is connected to the auxiliary coupling hole 114 in the assembled state S420. Moves along the hole 114, and finally approaches and approaches the arm tunnel part 130 to support the band so as not to be further tightened.

The tongue portion 150 is provided on the clamp band 100 on the opposite side of the hook portion 110 with a U-shaped or V-shaped recess.

The channel portion 160 is provided between the arm tunnel portion 130 and the hooking protrusion portion 120 and has a shape corresponding to the tongue portion 150 so as to be in close contact with the tongue portion 150.

5 is a view showing that the channel portion and the tongue portion are combined according to the present invention.

Referring to FIG. 5, it can be seen that the channel portion and the tongue portion correspond to each other with an embossed relief, while the tongue portion is closely attached to the lower end of the channel portion.
