After the position, the guide plate 98 is locked to the inner surface 90 of the lock cover 84, and the second lining member 133 that conforms to the size of the first latch 155 of the first box type latch device 153 is further selected to pass through the two screws 135. Engaged in the engaging member 117, in order to correspond to the position of the first latch 155 of the first cartridge type latching device 153, the second trim cover 251 is selected to be mounted on the front surface 22 of the socket 20.

In addition, the electric latch control device 10 is assembled into a second mode to select to assemble the closure member 177 and the blocking member 219 of the corresponding first tamper-proof latch 157 in the first chamber 28 of the socket 20 due to the A box type latch device 153 is not provided with an additional locking latch, so that it is necessary to fill the excess portion of the first chamber 28, and the closing member 177 is disposed in the first chamber corresponding to the first box type latch device 153. 28 is located near the upper position, and in order to fix the closure member 177 in the first chamber 28, the locking device 82 is first set to the unlocked state, and the locking device 82 is further pivoted to the non-closed position, see Figure 14. As shown, the side wall 193 and the two through holes 195 of the closure member 177 are exposed in the second opening 32, further allowing the two screw members 217 to pass through the two through holes 195, respectively, using a tool such as a screwdriver. And two assembly holes 191A, so that the respective screw members 217 can be separately placed in the accommodating portion 40 of the rail 38 Two square cross-section 217A of the first nut is screwed, so it can be housed in the upper end 177 on a fixed position in the first chamber 28 the first chamber 28 within the closure member.

The blocking member 219 is received in the first chamber 28 and aligned with the first tamper-proof latch 157 of the first box-type latch device 153 (between the detecting device 48 and the closing member 177), blocking The projection 231A of the member 219 is located in the through portion 42 of the rail 38, allowing the use of a screwdriver to pass a screw 235 through the combined end 231 of the blocking member 219 in a state where the locking device 82 is in the unclosed position. A second nut 235A received in the through portion 42 of the rail 38 is screwed so that the blocking member 219 can be fixed at a position corresponding to the first tamper-proof latch 157.

Referring to FIG. 16, when the first latch 155 is located in the first chamber 28, the first latch 155 abuts the pad 66 of the detecting device 48 in a non-touching position, as shown in FIGS. It is shown that the first tamper-proof latch 157 is compressed by the blocking end 233 of the blocking member 219 and is retracted. In a state where the first tamper-proof latch 157 is retracted, the first latching head 155 cannot be pressed from the outside. Thus, the first latch head 155 has an anti-snag effect, and the space remaining in the first chamber 28 without the first cartridge type latching device 153 is filled by the closing member 177 (as shown in Fig. 17).

Similarly, in a state where the lock device 82 is not locked, directly pushing the door enables the first latch 155 of the first cartridge type latch device 153 to press against the second liner member 133 to cause the lock cover device 82 to be closed. Pivoting to the non-closed position, the first latch 155 of the first cartridge type latching device 153 is restrained within the first chamber 28 of the socket 20 in a state in which the capping device 82 is locked.

Referring to Figures 19 and 20, it is assumed that the present electric latch control device 10 is assembled to cooperate with a third mode of a second box type latch device 159, the second box type latch device 159 including a A second latch 171, a second tamper-proof latch 173, and a locking latch 175 that can be controlled to extend or contract, the second tamper-proof latch 173 being located between the locking latch 175 and the second latch 171.

The electric latch control device 10 assembled in the third mode with the second cartridge type latch device 159 is configured to receive the locking latch restriction frame 197 and the blocking member 219 in the first chamber 28 of the socket 20, The locking latch limiting frame 197 can also be used with the two screwing holes 215 and the two mounting holes 199A and the additional mounting holes 199A and the two screwing holes 217 respectively when the locking device 82 is in the non-closed position. The two first nuts 217A in the accommodating portion 40 are screwed, so that the locking latch restricting frame 197 is fixed in the upper position in the first chamber 28, and the blocking member 219 is fixed in the locking latch restricting frame. Between the 197 and the detecting device 48, the outer side of the socket 20 is selected to assemble the second trim cover 251 on the front surface 22 such that the locking latch restricting frame 197 is aligned with the locking latch 175, and the second anti-snapping latch 173 is blocked. The member 219 is aligned and the second latch 171 is aligned with the detecting device 48.

When the door is closed, the locking latch 175 is received in the locking latch hole 213 of the locking latch restricting frame 197, and the second tamper-proof latch 173 is pressed by the blocking end 233 of the blocking member 219 to be retracted, the second latch The head 171 is housed in the first chamber 28.

Since the locking latch restriction frame 197 is locked in the first housing 28, when the locking latch 175 is located in the locking latch hole 213 of the locking latch restriction frame 197 (as shown in Fig. 19), the locking latch 175 cannot follow the door. Pivoting away from the locking latch restriction frame 197, so even if the locking cover device 82 is set to unlock, the second latching head 171 cannot push the locking cover device 82 from the closed position to the unclosed position, thus forming a lock.

When the locking latch 175 of the second box type latching device 159 is retracted from the locking latch hole 213 of the locking latch restricting frame 197, if the locking cover device 82 is set to the locked state, the second latching head 171 still cannot push the locking cover The device 82 pivots to the unclosed position out of the first chamber 28, thus forming a lock.

When the locking latch 175 of the second box type latch device 159 is retracted from the locking latch hole 213 of the locking latch restricting frame 197, if the locking cover device 82 is set to the unlocked state, the second latching head 171 can push the locking cover device 82. The pivoting to the unclosed position disengages from the first chamber 28 thus forms an unlock.

The electric latch control device 10 of the present invention can electronically control whether the door can be opened by installing only the electric latch control device 10 of the present invention without replacing the original cylindrical or box type latch device. The present electric latch control device can be quickly assembled into the first, second or third mode.
