Hereinafter, a locking device for installing a cleanroom roof panel according to the present invention (hereinafter, simply referred to as a 'locking device') according to the present invention will be described in detail with reference to the accompanying drawings.

Prior to the description, the roof panel 10 described below refers to a conventional roof panel for closing the ceiling space of a clean room by being connected to a mold bar having a length in the horizontal and vertical directions. A detailed description will be omitted.

First, as shown in FIGS. 2 and 3 , the locking device 1 according to the present invention largely includes a body member 100 and a binding member 200 .

In more detail, the body member 100 has a roof panel 10 or the roof panel 10 that is provided with a binding member 200 to be described later inside, and the outer surface is fixed to the roof panel 10 and opposed to each other. ) and the opposing mold bar are configured to be fixed between the lower body 110 and the upper body 120, and the lower body 110 and the upper body 120 are inside by fastening means such as bolts. It is detachably coupled so that the moving space 130 can be formed in the .

For example, in the lower body 110, a gear 111 having a predetermined length is formed on the inner bottom surface, that is, a through hole 121 perforated in the upper body 120 and a surface opposite to each other in the vertical direction, the gear 111 is formed. is toothed (齒) coupled to the outer surface of the rotary gear (220).

An exposure hole 113 is perforated on the outer surface of the lower body 110, and when the binding body 210 reciprocates within the movement space 130 through the rotary gear 220, it is displayed through the exposure hole 113 This allows the exposure of means 215 to be determined.

At this time, the exposed hole 113 perforated in the lower body 110 is also perforated on the outer surface of the upper body 120 opposite to the vertical direction, so that the display means 215 in both the upper and lower directions of the roof panel 10 . It is desirable to enable the identification of

The lower body 110 has a pair of stoppers 115 for controlling the moving distance of the binding body 210 in addition to the use for coupling the upper body 120 with the fastening means so that the lower body 110 is connected to the bottom surface. It is formed to protrude upward.

To this end, the stopper 115 having a column shape has a thread on the inner circumferential surface of the stopper 115 having a thread for screwing with the fastening means in the longitudinal direction, and the distance between the pair of stoppers 115 is a gap between the pair of stoppers 115 so that the binding body 210 moves reciprocally. Allowable distance, that is, a gap sufficient to expose or cover the display means 215 through the exposure hole 113 is made.

In addition, the outer surface of the stopper 115 may have a structure that is fitted with the binding body 210 that reciprocates, and a detailed description thereof will be described in more detail below.

In addition, the upper body 120 is a body member ( As a configuration for forming 100), it includes a through hole 121 and a flange 123 .

The through hole 121 is perforated on the outer surface of the upper body 120 so that the upper portion of the gear 111 and the rotary gear 220 that is tooth-coupled with each other can be exposed to the outside, and the through hole 121 is the rotary gear 220 ) is molded to have a long hole shape to enable movement.

As shown, the flange 123 is formed on either one end or the other end of the upper body 120 in order to be coupled to the outer surface of the upper body 120 as well as the end of the roof panel 10 in a shape-fitting manner.

Thus, when the locking device 1 according to the present invention is inserted into the insertion groove 11 formed in the roof panel 10 , the locking device 1 is stably supported on the roof panel 10 through the flange 123 . state that can be satisfied.

And as shown in FIGS. 4 to 7 , the binding member 200 is installed movably reciprocally within the moving space 130 formed in the body member 100 described above, and faces each other through the movement. The beam includes a binding body 210 and a rotation gear 220 in a configuration for an operator to easily identify with the naked eye whether the roof panel 10 is fixed or not.

For example, as shown in the figure, the binding body 210 is generally formed in the shape of a rectangular parallelepiped, and a long hole 211 is perforated therein.

At this time, the length of the long hole 211 is perforated to have a length that does not interfere with the gear 111 formed on the bottom surface of the lower body 110 in the process of the binding body 210 reciprocating within the movement space 130 . It is preferable to form

In addition, a pair of rotation grooves 213 are formed on the inner side of the long hole 211 facing each other to be symmetrically inserted into the rotation shaft of the rotation gear 220 to be rotatably inserted.

A display means 215 is provided on one side of the binding body 210 except for the long hole 211 portion, that is, on the outer surface of at least one of the upper surface or the lower surface in the direction in which the exposed hole 113 is formed, so that the binding body 210 moves in the direction of movement. The display means 215, which is discriminated by color, exposes or covers the exposure hole 113.

For example, the state in which the color of the display means 215 is exposed to the outside through the exposure hole 113 conveys the meaning of a warning to the operator, that is, a pair of roof panels ( 10) so that it can be recognized that there is no fixation between It is possible to visually recognize that the roof panels 10 are fixed to each other.

Meanwhile, a hook 217 extending from the inner surface of the long hole 211 in the present invention, that is, the inner surface of the binding body 210 facing each other with the stopper 115 interposed therebetween, and fittingly coupled to the outer surface of the stopper 115 is further formed. can be

Thus, the operator moves the hook 217 until a 'click' is heard on the outer surface of the strap 115 while the binding body 210 moves to lock or unlock the roof panel 10, and the binding body Whether the 210 has completely moved can be confirmed by sound or tactile sense.

In addition, as shown, the rotation gear 220 has the shape of a roller in which the rotation shaft is protruded from both sides, and a plurality of threads 221 are radially formed on the outer surface of the lower body 110, the gear 111 formed on the bottom surface. and tooth coupling to each other, thereby providing power for the reciprocating movement of the binding body 210 .

On the other hand, the binding member 200 in the present invention may additionally include a master mechanism 230 that allows only the operator to operate the rotary gear 220 uniquely, and the master mechanism 230 is It includes a branch 231 and an auxiliary rotation gear 233 .

As shown, the gripper 231 is formed in a columnar shape and has a structure in which an auxiliary rotation gear 233 can be rotatably coupled to the shaft, and the auxiliary rotation gear 233 has an outer surface as described above. It has a structure in which a screw thread is formed in the same way as the rotary gear 220 .

Thus, after the operator opens the rotating gear 220 or the cover plate 141 exposed to the outside through the through hole 121 , the screw thread of the rotating gear 220 exposed to the outside through the through hole 121 . The reciprocating movement of the binding body 210 is performed through an operation of pushing or pulling the binding body 210 in a direction in which the binding body 210 is to be moved by engaging the threads of the auxiliary rotation gear 233 with each other.

To this end, the uppermost point P of the rotation gear 220 exposed to the outside of the through hole 121 is located in the through hole 121 so that an unspecified number of people use an external force other than the master mechanism 230 to rotate the gear A predetermined distance D may be formed between the upper end of the through hole 121 and the uppermost point P of the rotation gear 220 so that the 220 cannot be arbitrarily rotated.

On the other hand, in the present invention, the upper body 120 physically moves the rotating gear 220 after or before the binding body 210 moves through the rotation of the rotating gear 220 to be described later in another embodiment. It may further include a sliding preventing means 140 for preventing the movement of the binding body 210 by fixing, the sliding preventing means 140 is a first preventing member for physically fixing the rotary gear 220 or The reciprocating binding body 210 and the lower body 110 may further include at least one of the second preventing member for attaching and detaching the portion that is in contact with each other by magnetic force.

For example, as shown in FIG. 9 , the first preventing member includes a cover plate 141 , a jaw 143 , and a locking groove 145 molded of a transparent material so that the rotary gear 220 can be visually identified from the outside. include

The cover plate 141 has a rotating shaft protruding on both sides so that one side can be rotatably coupled to the upper body 120 , and the outer surface has a ring shape to have a shape corresponding to the shape of the through hole 121 . and a chin 143 protruding into the .

At this time, a locking groove 145 having the same shape as that of the above-described gear 111 is formed on the outer surface of the cover plate 141 located inside the jaw 143 , and through the rotation of the cover plate 141 , a through hole 121 . It is preferable to have a structure in which the locking groove 145 and the outer surface of the rotary gear 220 are tooth-coupled to each other after closing the rotary gear 220 .

Through the tooth engagement between the engaging groove 145 and the rotating gear 220 and the forced fitting between the jaw 143 and the through hole 121, the rotation of the rotating gear 220 is prevented twice, which is the binding body. The advantages of accompanying the fixation of 210 are implemented.

In addition, as shown in FIGS. 10 and 11 , the second preventing member has a lower portion adjacent to each other in the direction in which the third magnet M3 provided on the lower surface of the binding body 210 and the binding body 210 move. It includes first and second magnets (M1.M2) formed on the body (110).

Thus, as shown, in a state in which the binding body 210 does not protrude to the outside of the body member 100, that is, in a state in which the lock is not executed, the first and third magnets M1 and M3 are magnetically applied to each other. It is attached to fix the binding body 210, and in a locked state in which the binding body 210 protrudes to the outside of the body member 100, the second and third magnets M2 and M3 are attached to each other by magnetic force. to have a structure in which the binding body 210 can be fixed.

Of course, the magnetic force of the first to third magnets uses a magnet body having enough magnetic force to be maintained until the rotation gear 220 is physically rotated using the master mechanism 230 by the external force of the operator. .

Hereinafter, with reference to the accompanying drawings, it will be described in detail with respect to the action relationship of the locking device 1 according to the present invention.

Prior to the description, in order to clearly understand the gist of the present invention, the coupling between a pair of roof panels 10 facing each other using the locking device 1 is described as an embodiment, but this is one embodiment. It is only possible to combine with a mold bar.

First, as shown in FIG. 8 , the locking device 1 is fixedly coupled to the insertion groove 11 formed in the roof panel 10 through a fastening means.

Here, as for the locking device 1 , it is also possible to install the locking device 1 on any one side or two sides based on a rectangular plate shape.

Thereafter, the operator operates the thread of the auxiliary rotation gear 233 of the master mechanism 230 and the thread of the outer surface of the rotation gear 220 exposed to the outside through the through hole 121 for coupling between the pair of roof panels 10 . After the 221 are bitten so that they can be teeth-coupled to each other, an external force is applied in the direction of the roof panel 10 to be bound (see FIGS. 6 and 7 ).

Then, the rotation gear 220 rotates along the rotation groove 213 while the screw thread 221 formed on the outer surface engages with the gear 111 formed on the lower body 110 and moves, and through this movement, the binding body 210 ) As the whole moves in the direction of the outer wall, one side of the binding body 210 protrudes outward through the open portion of the body member 100, that is, it is inserted into the coupling groove 13 of the roof panel 10 to be bound. A fixed coupling between them is possible.

At this time, the display means 215 exposed to the outside through the exposure hole 113 is a body member so that the color of the display means 215 is not exposed through the exposure hole 113 due to the movement of the binding body 210 . (100) is hidden inside, and an operator who has identified this state recognizes that fixing has been performed between the pair of roof panels 10 (see FIGS. 4 and 5).

Of course, when the pair of roof panels 10 bound to each other are released from each other, the above-described process is performed in the reverse order to release.

On the other hand, in the locking device 1 in the present invention, as shown in FIGS. 12 and 13 , the through hole 121 formed in the upper body 120 is perpendicular to the through hole 121 . The gear 111 is additionally formed on the outer surface of the lower body 110 so that the shape of the gear 111 can be partially cut out, so that the operator uses the master mechanism 230 even on the lower surface of the roof panel 10 to be formed on the lower surface of the lower body 110 . It is also possible to perform movement of the binding body 210 by rotating the rotary gear 220 through the through hole 121 .

As described above, the locking device 1 according to the present invention is differentiated from the prior art by simplifying the configuration for the movement of the binding body 210 to reduce the manufacturing cost and at the same time, it is easy without applying an external force more than necessary. As the binding body 210 is reciprocally moved, it can be fixed or released, thereby having the effect of reducing the fatigue of the operator.

As described above, in the present invention, specific matters such as specific components, etc., and limited embodiments and drawings have been described, but these are only provided to help a more general understanding of the present invention, and the present invention is not limited to the above embodiments. , various modifications and variations are possible from these descriptions by those of ordinary skill in the art to which the present invention pertains.

Therefore, the spirit of the present invention should not be limited to the described embodiments, and not only the claims to be described later, but also all those with equivalent or equivalent modifications to the claims will be said to belong to the scope of the spirit of the present invention. .
