Abstract

More particularly, the present invention relates to a lock for a cable tray cover, more specifically, a locking means for locking the lower edge of the tray, and an upper surface of the cover by pressing the upper surface of the cover using self- The locking mechanism can be used to lock the lid on the tray. In this case, the locking mechanism is not applied to the cover, It is possible to greatly reduce the length of the lid locking operation compared with the conventional bolt fastening method and also to easily remove the locking lug during the repair or replacement of the cable, So that convenience can be given.

Description

The locking structure for a cable tray cover includes a cover for a cable tray,

In order to drive various electric facilities and control facilities in the factory, a plurality of cables are used in the factory. It is necessary to provide a system that keeps these cables in an apparently organized state while guiding the cables to the necessary places in the factory. There is a ladder type cable tray system in this role.

5 and 6 show a general ladder-type cable tray 40,

(41) for guiding the cable to a desired position while preventing the cables from being separated from each other and a cable support rod (41) for supporting the load of the cable (C) while connecting the two side plates 42 as shown in FIG.

A cover 43 is provided on the upper side of the upper side plate 41 to protect the cables disposed on the cable support rods 42 from falling objects such as snow, rain, dust, etc. and cables from sunlight It is common.

The cable tray 40 constructed as described above is constructed such that the cable C is placed on the cable support rod 42 inside the both side plates 20 and then the upper side of the cable tray 40 is covered with the cover 43 on the upper surface of the side plate 40, The upper and lower fixing pieces 50A and 50B surround the outer surfaces of the lid 43 and the side plate 41 and fix the screw fixing holes 51A and 51B of the upper fixing piece 50A and the lower fixing piece 50B, Tight fitting structure in which the upper fixing piece 50A and the lower fixing piece 50B are tightly fixed to each other by using bolts B, washers W and nuts after the upper and lower fixing pieces 51B are aligned.

However, such a coupling structure has a large number of parts, such as a cover 43, an upper fixing piece 50A, a lower fixing piece 50B, and bolts B, a washer W, and a nut N, It is necessary to unfasten the bolts and re-tighten the bolts even during maintenance such as repair or replacement of the cables, resulting in a decrease in work efficiency and inconvenience in handling The problem is exposed.

In addition, due to the increase of the weight due to a lot of binding parts, there is a fear that the stability of the installation is deteriorated due to the characteristics of the cable tray installed in the suspension type, which has a bad influence on the durability.

In addition, the registration structure No. 20-0421646 entitled "Covering structure of ladder type cable tray system" discloses a structure in which a fixing hole is drilled on the upper surface of a cover and a tray, However, since the drilling operation is also necessary, it is impossible to avoid the increase of the work process, the structural strength due to the drilling and the detachment of the fixing nail if necessary are difficult, and the problems of the detachment of the fixing nails are damaged Was exposed.

Thus, in the present invention, in fixing the cover to be put on the tray,

The locking member can be locked and unlocked quickly and easily by only locking the locking member in a self-locking structure and elastic friction without using a bolt locking method as in the prior art. .

In the construction of the lock for achieving the above object,

The present invention is characterized in that a lower end of a main body of the locking claw is provided with a locking piece which is bent inward and which can be hooked on a lower end portion of the tray, and a locking request.

In addition, the present invention is characterized in that the upper end of the main body is provided with a downwardly inclined elastic gripping part for pressing the upper surface of the lid by using the self-elastic force so as to maintain the locked state through the pressing frictional force.

In the present invention, in fixing the cover to be put on the tray,

It is possible to lock the cover through only the engagement and the elastic frictional force exerted in the self-locking structure of the locking claw without applying the bolt fastening method, thereby making it possible to significantly shorten the process of locking the cover locking operation compared to the conventional bolt locking claw, The removal of the locking mechanism can be performed quickly and easily, thus providing convenience in handling maintenance and the like.

FIG. 1 is a perspective view showing a configuration example of the inventive locking mechanism, FIG. 2 is a perspective view showing a state in which the present invention is applied to a tray and a cover,

Two side plates 11 provided opposite to each other to guide the cable C and having a bent end 12 perpendicular to the upper and lower edges thereof and a plurality of cable support rods 13 supporting the cable C on the upper side And a plate-like lid 20 which is openably and closably provided on the upper portion of the cable tray 10. In this known structure,

A locking hole (30) for connecting the cover (20) to the cable tray (10)

The locking member (30)

A latching piece 32 integrally bent inwardly at the lower end of the plate-like body 31 so as to have a latching request 33 that can be hooked on the bent end 12 of the side plate 11,

The upper end of the main body 31 on the plate body is bent downward in the same direction as the engaging piece 32 and contacts the lid 20 mounted on the cable tray 10 to apply a locking force And an elastic supporting piece 34 for supporting the elastic supporting piece.

It is preferable that the locking member 30 of the present invention constructed as described above is applied to a steel plate having excellent elasticity due to its functional characteristics, but it is not limited thereto.

The locking hole 30 of the present invention is not required to be additionally provided in a general cable tray 10 composed of a side plate 11 having a folded end 12 perpendicular to the lower edge as shown in Figs. In the case of a structure immediately applicable but without a bent end, for example in the case of a cable duct enclosed in a downward direction, a separate latching end can be additionally provided on the underside of the duct to engage the latching need 33, .

2, in order to fix and support the lid 20 covered by the cable tray 10 using the locking hole 30 of the present invention, the locking hole 30 is first laid down as shown in FIG. 4, The locking part 30 is pivoted upward about the latching part in a state in which the bent end 12 of the side plate 11 is slightly engaged with the latching request 33 at the lower end.

It is needless to say that the position of the lifted elastic gripping piece 34 should be dimensioned so as to have a position relatively lower than the height of the lid 20 as shown by the dotted line in FIG.

Therefore, the elastic gripping piece 34 is lifted above the lid 20 so as not to exert the fixing force unless an additional external force is applied. Therefore, the elastic gripping piece 34 is artificially applied as shown by the arrow, The elastic gripping pieces 34 are completely rotated and the elastic gripping pieces 34 are positioned on the lid 20. When the elastic gripping pieces 34 are returned to the circular shape and the lid 20 And at the same time an elastic pressing force is applied to the lid 20.

The locking hole 30 of the present invention to be mounted as described above is provided with a constant elastic pressing force in the closing direction to the lid 20 in a state where the lower end is supported by the side plate 11 and the upper end is supported by the lid 20, The cover 20 can be supported and fixed.

If it is necessary to open the lid 20 for replacement of the cable C, the end of the resilient supporting piece 34 is pushed outward by using a tool, The elastic gripping piece 34 is released from the lid 20 and the lid 20 can be unlocked.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled 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. Of course.
