DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

2 is a photograph showing the portable receptacle 200 fixed to the portable receptacle fixing apparatus 100 according to the present invention. 3 is a photograph showing the back surface of the portable receptacle fixing apparatus 100 according to the present invention in which the portable receptacle 200 is fixed.

The portable receptacle fixing apparatus 100 includes a body 110 and a cable locking means 120. The portable receptacle 200 is received and fixed in the guiding groove 111 surrounded by the guide 112 in the body 110. The portable receptacle 200 may be fixed to the body 110 by screws passing through the lower case. Referring to FIG. 3, it can be seen that two screws (red circle) are used to fix the portable receptacle 200 to the body 110.

The cable locking means 120 is coupled to an upper portion of one side of the body 110 so as to cross a cable connected to the portable receptacle 210. Four screws (121) are used for coupling the cable locking means (120). Since the movement of the cable 210 is blocked by a fixing power provided by the cable locking means 120, cutting or stretching of the cable 210 can be prevented.

Hereinafter, the structure of the portable receptacle fixing apparatus 100 will be described in detail with reference to FIGS. 4 and 5. FIG.

4 is a detailed view of the body 110 of the portable receptacle fixing apparatus 100 according to the present invention. 4 (a) is a plan view of the body 110, FIG. 4 (b) is a right side view of the body 110, and FIG. 4 (c) is a front view of the body 110 .

5 shows a detailed view of the cable locking means 120 of the portable receptacle fixing apparatus 100 according to the present invention. 5 (a) is a plan view of the cable locking means 120, FIG. 5 (b) is a front view of the cable locking means 120, and FIG. 5 (c) And the cable locking means (120).

A coupling structure for coupling the cable locking means 120 is formed on one side of the body 110. A second groove 114 corresponding to the first groove 123 provided at the lower portion of the perfume cable locking means 120 is formed in the coupling structure. When the body 110 and the cable locking means 120 are coupled to each other, the first and second grooves 114 and 123 form a through hole of the cable 210 (refer to FIG. 5C) ). In addition, the coupling structure includes a borehole 113 used for coupling the cable locking means 120.

The cable locking means 120 is provided at the lower portion with the first groove 123 forming the through hole for the cable 210 together with the second groove 114 described above. And the cable locking means 120 is provided with a screw hole 122 used for coupling with the body 110. [

In FIGS. 4 and 5, the first and second grooves 114 and 123 have a semicircular shape. However, in other embodiments of the present invention, the first and second grooves 114 and 123 may have a semi-elliptical shape, a rectangular shape, or a triangular shape.

The clamping force applied to the cable 210 can be controlled according to the locking level (locking degree) of the cable locking means 120. The locking level of the cable locking means 120 may be adjusted by the number of screws connecting the cable locking means 120 and the body 110, the depth of coupling of the screws, the position of the screws, and the like.

This is because the portable socket fixing device according to the present invention which can control the cable fixing force through the adjustment of the locking level can change the diameter of the cable through hole of the portable socket outlet in consideration of the thickness of the cable connected to the portable socket outlet, This means that it is possible to provide a stable fixing force even for thick cables.

6 to 9, the structure of the portable receptacle fixing device 100 according to the present invention for preventing the cable 210 from being stretched or broken due to an external force or an impact will be described more concretely .

6 to 9 show examples of various cable through holes that can be formed in the portable receptacle holding apparatus 100 according to the present invention. For reference, Figs. 6 to 9 show an enlarged cross-sectional view of a portion where a cable through hole is formed. In order to distinguish the body from the locking means itself, in FIG. 6 to FIG. 9, the member number of the body is 110A and the member number of the locking device is 120A in the case of a cross section.

Referring to FIG. 6, it can be seen that the diameter of the cable through hole formed by the cable locking means 120A and the body 110A gradually decreases from the inside of the body 110 to the outside. That is, the diameter D1 of the cable through hole on the inner side of the portable receptacle holding device 100 is larger than the diameter D2 on the outer side of the portable receptacle holding device 100. [

In this case, when the cable 210 is tightly coupled to the cable through-hole, a fixing force for pulling the cable from the outside of the portable socket-fixing device 100 is applied to the cable from the outside of the portable socket- It can act more than the clamping force on the pushing force. The mechanical structure that can provide the above-mentioned effect may be the structure of FIG. 7 (b), the structure of FIG. 8 (b), and the like. However, the structure of the cable through hole capable of providing the above-described effect is not limited to the above-described examples.

7, projecting means 113A and 123A having a curved cross section for reinforcing the fixing force to the cable 210 are formed in the grooves of the body 110A and the cable locking means 120A forming the cable through hole As shown in FIG. In particular, referring to FIG. 7 (b), it can be seen that the inclination of the protruding means 113A and 123A inward of the portable receptacle fixing apparatus 100 is higher than the inclination of the portable receptacle fixing apparatus in the outward direction. The structure for enhancing the fixing force against the pulling force externally of the portable receptacle fixing apparatus 100 has been described above.

7, the protruding means may be formed only on one of the body 110A and the cable locking means 120A, and the body 110A, And only one projecting means may be formed on the cable locking means 120A.

The example of Fig. 8 has the same or similar features as the example of Fig. 7, except that the cross section of the projecting means formed on the body 110A and the cable locking means 120A is serrated. Therefore, a detailed description of FIG. 8 is omitted.

9, a first protrusion 123A is formed in the first groove of the cable locking means 120A so as to be in close contact with the cable 210 while crossing the cable 210, The second groove of the body 110A is tightly coupled to the cable 210 while crossing the cable, and one second protruding means (not shown) alternating with the at least one first protruding means 123A 113A are formed.

Due to such a structure, the cable 210 is subjected to a force that is opposite to the direction of operation and is staggered with respect to each other, so that a more stable fixing force can be applied to the cable 210 than a force or an impact acting on the cable 210. 9, in other embodiments of the present invention, only one of the body 110A and the cable locking means 120A may have a protruding means or a plurality of protruding means may be provided . The protruding means formed on the body 110A or the cable locking means 120A may have a shape for giving a larger fixing force to the force for pulling the cable from the outside.

Although not shown in the drawings, in another embodiment of the present invention, the cable locking means 120 is formed with a first groove and a tightening portion tightly coupled to the cable and the tightening portion are coupled and the cable locking means 120 And a fixing portion that forms an upper portion of the fixing portion. In this case, the coefficient of friction of the tight contact portion with respect to the cable is preferably larger than the coefficient of friction of the secure portion with respect to the cable. For example, the inspection portion may be made of a material having a large coefficient of friction with respect to cables such as urethane or rubber, and the fixing portion may be made of plastic or noble metal.

10 and 11 are conceptual diagrams showing various examples in which the cable locking means 120 is coupled to the body 110 in the portable receptacle fixing apparatus according to the present invention.

Referring to FIG. 10 (a), it can be seen that the cable locking means 120 can be coupled to the body 110 by screws. Referring to FIG. 10 (b), it can be seen that one side of the cable locking means 120 is fixed to the body 110 in a hinged configuration, and the other side is fixed to the body 110 with screws.

11, one side of the cable locking means 120 is fixed to one side of the cable in the transverse direction of the cable 110, and the other side of the cable locking means 120 is supported by a force applied in the vertical direction, And ratchet teeth 125 that are ratchetically engaged with ratchet teeth 115 provided on the other side of the cable in the transverse direction of the body 110. [

The ratchet coupling between the cable locking means 120 and the body 110 applies a right force to the protruding means 117 formed on the body 110 so that the ratchet teeth 115 provided on the body 110 It can be released by releasing the applied pressure elasticity. In Fig. 11, a spring is used as the pressing elastic means. However, the scope of the present invention is not limited thereto.

The coupling structure of the body 110 and the cable locking means 120 of FIG. 11 can be adjusted by adjusting the degree of ratchet coupling so that the locking level of the cable locking means 120 is adjusted, And is an example of a mechanism for controlling the clamping force applied to the cable. Meanwhile, the coupling structure for performing the cable fixing force control by adjusting the locking level may be implemented by various coupling structures other than the above-described ratchet coupling structure. That is, the portable socket fixing device according to the present invention, which can control the cable fixing force through the adjustment of the locking level, can provide a stable fixing force even to cables of various thickness connected to the portable socket-outlet.

12 shows an example of the body of the portable receptacle fixing apparatus according to the present invention.

Referring to FIG. 12, it can be seen that a plurality of holes 118 for draining are formed in the guiding grooves 111 of the body 110. Here, the hole 118 penetrates to the bottom of the body 110. Meanwhile, the number, shape, and position of the holes for draining that can be provided in the portable receptacle fixing apparatus according to the present invention are not limited to the example shown in FIG.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible.

Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the claims.
