Description

  The present invention relates to a sealed lock that completely locks the locked state after a locking operation and seals a container or the like to which the lock is attached, and more particularly to a sealed lock suitable for sealing an electronic circuit case of a gaming machine.

  For example, in a pachinko machine, in recent years, the payout rate when winning a prize is controlled by an electronic circuit (controller). This type of controller is housed in a case and closed in order to prevent modification in a pachinko hall or the like that is actually used. However, the controller needs to be adjusted and inspected in multiple stages, such as the stage where it is assembled by an electrical manufacturer, the stage where it is installed in a pachinko machine by a pachinko machine manufacturer, and the stage where it is installed in a pachinko hall. The case cannot be completely sealed at the first stage.

  For this reason, the controller of this type of pachinko machine is inserted into the case and attached to the pachinko machine, sealed at the end of the final inspection when the pachinko machine is delivered to the pachinko hall, and used as a modification impossible. However, since the case is usually sealed by sticking a predetermined seal to the case door, the sealed seal is peeled off using a special solvent, and then attached to the original state again. There was a case where the seal was broken so as not to understand.

In view of this, the present inventor has proposed a sealed tablet that can be locked and unlocked completely by the final locking operation after the predetermined number of times of locking and unlocking in Patent Document 1 below.
JP-A-10-252325

  This sealed lock can be locked / unlocked while the lock shaft is rotated and unlocked and unlocked a predetermined number of times. When the final locking operation is performed, the lock pin is inserted into the rotor locking hole. And the rotor and the lock shaft can be satisfactorily sealed in a locked state. However, when the lock pin is removed from the lock hole for some reason, the seal may be released and the lid may be opened again, and there has been a demand for a sealed lock that can be reliably sealed.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a sealed tablet that can completely lock a locked state after a locking operation and put a container to which the lock is attached into a so-called sealed state. To do.

  In order to achieve the above object, a sealed tablet according to claim 1 of the present invention includes a cylindrical case having a hole for a lock shaft on the front surface, and a lock body fixed in the case and having a shaft hole for the lock shaft. A lock shaft that is inserted into the shaft hole of the lock body and has a groove for turning operation at the tip, and a lock lever that is fixed to the end of the lock shaft, and seals the locked state after the lock operation In the lock, an adhesive container in which an adhesive is encapsulated is stored in the lock body, and a blade-like sharp head protrudes from the outer periphery of the lock shaft so as to be able to contact the adhesive container, and the lock shaft is rotated toward the locking side. Then, the pointed head breaks the adhesive container, and the lock shaft is fixed to the lock body by the adhesive flowing out of the adhesive container.

  Here, the blade-shaped pointed head provided on the outer peripheral portion of the lock shaft is disposed along the circumferential direction between the outer peripheral portion of the lock shaft and the inner peripheral portion of the lock body, and the lock shaft is disposed at a predetermined angle or more. When turned to the unlocking side, the tip of the pointed head can be moved outward to be able to pierce the adhesive container.

  Further, the sealed lock of claim 3 includes a cylindrical case having a hole for a lock shaft on the front surface, a lock body fixed in the case and having a shaft hole for the lock shaft, and a shaft hole of the case and the lock body. A locking lock that is inserted and has a lock shaft provided with a groove for turning operation at the tip and a lock lever fixed to the end of the lock shaft, and seals the locked state after the locking operation. When an adhesive container filled with adhesive is stored and a blade-like pointed head protrudes from the outer periphery of the lock shaft so that it can contact the adhesive container, and the lock shaft is illegally turned to the unlocking side, The head breaks the adhesive container, and the adhesive flowing out from the adhesive container adheres to the lock shaft and the lock body, leaving a trace.

  The sealed lock having the above structure is attached to a door or lid of a box or the like, and is used for locking / unlocking the door or the like and subsequent sealing.

  In the sealed lock according to the first aspect, the lock shaft is inserted into a groove at the tip of a coin, a driver, and the like, and is rotated within a predetermined angle range. The lock lever is unlocked by one-way rotation, and is rotated in the other direction. Moves to the locked position.

  When the lock shaft is rotated within a predetermined angle range, the blade-like cusp provided on the outer periphery of the lock shaft is stored in an arc shape between the lock shaft and the lock body, and the lock shaft is rotated. The pointed head does not break through the adhesive container during the moving operation. Therefore, the locking / unlocking operation can be performed a plurality of times.

  On the other hand, when sealing a sealed lock, the lock shaft is turned to the unlocking side beyond a predetermined angle range, whereby the pointed end of the pointed head is moved outward to be able to pierce the adhesive container. In this state, when the lock shaft is rotated to the locking side, the pointed head rotates together with the lock shaft, breaks through the adhesive container housed in the lock body, and the lock shaft rotates to the locking position. As a result, the adhesive flows out from the adhesive container between the lock body and the lock shaft. When a cyanoacrylate adhesive (instant adhesive) that cures in a short time is used as an adhesive, the lock shaft is bonded to the lock body in a short time, and the sealed lock opens when it is not locked or broken. It becomes a sealed state that can not be.

  Further, in the sealed lock of claim 3, when the lock shaft is turned to the locking side beyond the predetermined angle range, the pointed end of the pointed head moves to the outside and can be stabbed into the adhesive container. In this state, if the lock shaft is illegally rotated to the unlocking side, the pointed head rotates together with the lock shaft, pierces the adhesive container stored in the lock body, and the adhesive is locked to the lock shaft and the lock. It flows out between the main bodies. In this state, when the lock shaft is rotated again to the locking position, the lock shaft is fixed to the lock body by the adhesive, the lock is sealed, and the traces of unauthorized unlocking due to the outflow of the adhesive are locked. Will remain.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a front view of the seal lock attached to the door 6 of the box 7, and FIGS. 2 and 3 show sectional views thereof. This sealed tablet basically includes a substantially cylindrical case 1, a lock body 4 fixed in the case 1, an adhesive container 2 housed in the lock body 4 so as to be destructible, and a lock body 4.

The lock body 4 is formed in a cylindrical shape having a substantially circular shaft hole through which the lock shaft 3 can be inserted, and is adjacent to the hole for the lock shaft 3 and has an adhesive container shaped as shown in FIGS. 2 is stored. The adhesive container 2 is filled with a cyanoacrylate adhesive (instant adhesive) that cures in a short time, and the container can be pierced by a pointed head 32 provided on the outer periphery of the lock shaft 3 to be described later. It is formed as a thin synthetic resin container.

  Further, as shown in FIG. 7, a substantially crescent-shaped internal space 41 is formed along the circumferential direction at a position in the lock body 4 adjacent to the shaft hole and adjacent to the adhesive container 2. In addition, when the pointed head 32 provided on the outer periphery of the lock shaft enters, the pointed head 32 can move so as to open outward due to its spring elasticity.

  A lock shaft 3 as shown in FIG. 5 is inserted into the shaft hole of the lock body 4 in the case 1. The lock shaft 3 is formed with an operation groove 31 into which a coin, a driver or the like can be inserted at the tip thereof, and a blade-like pointed head 32 for breaking the adhesive container 2 can protrude from the outer periphery of the intermediate portion. Is provided. As shown in FIG. 5, the pointed head 32 is formed along the circumferential direction of the outer peripheral portion of the lock shaft 2 with the tip of a thin arc-shaped body having an acute angle, and the arc-shaped body has spring elasticity. And has a free state that projects outward. When the pointed head 32 slides on the inner surface of the adhesive container 2, the pointed head 32 is pushed by the inner peripheral surface of the container and accommodated in a circumferential groove formed in a part of the outer peripheral surface of the lock shaft 3. . On the other hand, as shown in FIG. 7C, when the pointed head 32 reaches the internal space 41 by the rotation of the lock shaft 3, the pointed head 32 spreads outward and protrudes due to spring elasticity.

  Further, an operation groove 31 is formed at the tip of the lock shaft 3 so as to be rotated in a predetermined range by a coin or the like (here, in a range of about 90 degrees to the right). Further, a fitting portion 33 for fitting the lock lever 5 is formed at the end of the lock shaft 3, and the lock lever 5 is fitted so as to bend the fitting portion 33 inward.

  As shown in FIG. 2, a rotating plate 13 is disposed between the flange 11 on the front surface of the case 1 and the lock body 4 so as to display the presence or absence of sealing on a window 12 provided on the flange 11. For example, when the green and red portions are colored and formed on the rotating plate 13 and sealed, red is displayed in the window 12 instead of green. For this purpose, for example, a ratchet claw and an engaging portion (not shown) are provided between the rotary plate 13 and the lock shaft 3, and the rotary plate 13 is not rotated when the lock shaft 3 is rotated within a certain angle range. First, green is displayed on the window 12. On the other hand, when the lock shaft 3 rotates to the right beyond a certain angle range, the ratchet pawl engages with the engaging portion, and when the lock shaft 3 is rotated to the left and sealed in this state, the rotary plate 13 Rotates in response to the rotation of the seal, and the window 12 displays red indicating the seal.

  When assembling the sealed lock, the lock shaft 3 and the lock body 4 are assembled in the case 1 with the adhesive container 2 housed in the lock body 4, and the lock lever 5 is attached to the fitting portion 33 at the end of the lock shaft 3. It is inserted. The lock lever 5 is formed in a shape that can be locked to the receiving portion 8 fixed to the box 7 side. The case 1, the lock shaft 3, the lock body 4, and the lock lever 5 can all be formed of a hard synthetic resin such as ABS resin. The pointed head 32 can be formed integrally with the lock shaft 3, but can also be formed of a spring metal.

  As shown in FIGS. 1 and 4, the sealed lock configured in this way is attached to a door 6 of a box 7 for storing an electronic circuit of a pachinko machine, for example. This mounting can be easily mounted by inserting a sealing lock into the hole of a predetermined size formed in the door 6 from the front side and fitting the check claw 14 on the outer periphery of the case 1 to the edge of the hole. it can. Then, the lock lever 5 is fitted to the end of the lock shaft 3. At this time, the lock shaft 3 is set at an unlocked position and within a predetermined angle range (as shown in FIG. 7b, the lock lever 5 is raised by 10 degrees above the horizontal position, for example). Is set so that the green of the rotating plate 13 is displayed.

  In the case of a pachinko machine, an electric manufacturer usually stores an electronic circuit in a box 7, the door 6 is closed, a coin, a driver, etc. are inserted into the operation groove 31 of the lock shaft 3, and the lock shaft 3 is moved to the left. Turn 80 degrees. At this time, the lock bar 5 at the end of the lock shaft 3 rotates to the 12 o'clock position as shown in FIG. 7A, the lock lever 5 is locked to the locking portion 8 on the box 7 side, and the door 6 is Locked. At this time, as shown in FIGS. 7A and 7B, the pointed head 32 on the outer peripheral portion of the lock shaft 3 slides inside the adhesive container 2, and the pointed end of the pointed head 32 holds the container 2. There is no breakthrough.

  Next, such a box 7 containing an electronic circuit is sent to, for example, a pachinko machine maker and mounted in the pachinko machine, but is unlocked to open the box at the time of inspection or the like. When a coin, a driver, or the like is inserted into the operation groove 31 of the lock shaft 3 and rotated to the right by a predetermined angle range (for example, about 80 degrees) and unlocked, as shown in FIG. 7B, the lock shaft 3 At the same time, the lock lever 5 rotates to the unlocking position, disengages from the locking portion 8 and is unlocked.

  When the door 6 is closed and locked again after inspection and adjustment of the electronic circuit, a coin, a driver, etc. are inserted into the operation groove 31 of the lock shaft 3 and the lock shaft 3 is moved to the left. Turn 80 degrees. At this time, the lock bar 5 at the end of the lock shaft 3 rotates from the position 7 o'clock to 12 o'clock as shown in FIGS. Locked and the door 6 is locked. At this time as well, as shown in FIGS. 7A and 7B, the tip 32 of the lock shaft 3 slides inside the adhesive container 2, and the tip of the tip 32 breaks through the container 2. Absent.

  Next, when the pachinko machine is installed in the pachinko hall and the box 7 is opened for inspection and adjustment after installation, unlocking is performed. Similarly to the above, when a coin, a driver or the like is inserted into the operation groove 31 of the lock shaft 3 and turned to the right by about 80 degrees, the lock lever 5 is unlocked together with the lock shaft 3 as shown in FIG. Rotate to position and unlocked.

  Then, after the electronic circuit is inspected and adjusted, when the door 6 is closed and locked again, a coin, a driver or the like is inserted into the operation groove 31 of the lock shaft 3 and the lock shaft 3 is moved to the left. Turn about 80 degrees. At this time, the lock bar 5 at the end of the lock shaft 3 rotates from the position 7 o'clock to 12 o'clock as shown in FIGS. Locked and the door 6 is locked.
