(Means for solving the problem) 5 321489 201105850 = Li Qing] The invention of the item is a door lock device, and the length of the body of the two The front concave portion houses an operating handle, and the bearing cylinder portion on the surface of the upper side of the body is accommodated; the head of the operating handle is centered on the horizontal frame axis by the horizontal two hunting Holding the front concave portion to pull out 'rotating the circumference of the lock after the pivoting pulls out', thereby fixing the buckle portion fixed to the above-mentioned upper lock shaft: body: the buckle portion is disengaged to release the aforementioned door The locking device of the door is characterized in that: the lower end portion of the operating handle is formed in the up-and-down direction and orthogonal to the rear end portion of the locking portion, and the guiding portion is formed in the up-and-down direction. :Γ: The body is inserted in such a way that it can slide in the up-and-down direction, and the locking groove portion of the wall portion is engaged and disengaged, in front; Portion: a rectangular cam follower hole is formed in the intermediate portion, and the latch is locked in the aforementioned lock, and the rear end portion of the rotor of the lock unit is inserted from the cam follower hole; the movable cam is inserted into the flash lock body. The longitudinal dimension and the lateral dimension of the cam follower hole are both larger than the diameter of the movable cam protrusion 'in the aforementioned shell Body (4) Front side position of the lock groove portion] The cam slope portion connected to the front side is formed on the side of the rotor which is rotated by the key inserted into the rotor of the rotor, and the side of the rotor is rotated by the other. The portion pushes the lower edge portion of the cam follower hole to retreat the aforementioned lock body to the guide slot hole, and the detachment claw portion of the lock body is detached from the lock groove portion of the case body, and the other ^, when the previous steam key is stopped to rotate the rotor, the aforementioned claw portion of the flash lock body protrudes from the guiding groove by the longitudinal dimension of the cam follower hole and the foregoing The length of the difference in the size of the diameter of the driving cam protrusion is 'when the handle is pushed into the front surface concave portion of the casing body, the back portion of the claw portion is pressed by the cam slope portion on the side of the casing body, so that The flash lock body is pushed into the guide slot hole against the pushing force of the spring member. The invention of claim 2 is in the scope of patent application! In the invention of the invention, the dimension of the longitudinal direction of the handle is set to be shorter than the dimension of the longitudinal recess of the cover body, and the difference in the dimension of the longitudinal direction is used in the state in which the handle is embedded. The front concave portion == the finger tip insertion portion, and the fingertip hook portion for the region φ d above the private insertion portion is formed at the lower end portion of the operation handle. (Effect of the invention) Μ 专 专 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四 四The locking part of the recessed part with the locking claw (4) attached to the side of the shell body is in the buried position. The 卩(10) body and the lock slot card 5 grievances are maintained by the elastic member I received in the guide slot of the operating handle. m By turning the remaining key inserted into the keyhole of the rotor and driving the cam 321489 7 201105850 ίίίΓ (4) under the cam follower hole, the _ body is returned to the hole, and by making the latch body The claw portion is separated from the shell portion and the solution is (4) compared to the shell body. # f Hold the manuscript in the original swivel position and center the horizontal pivoting unit: Pull the handle diagonally (to pivot the handle) to the front side of the shell body. When the picker's keyhole of the rotor is pulled out of the key, the flash lock body is pushed up by the spring structure and pushed upwards. The pawl portion protrudes from the guide slot. Then, by rotating the handle around the lock shaft, the engagement between the fixed metal plate and the socket portion is released, and the door is unlocked from the fixed frame. After the operation is completed, the door is closed again, the handle is rotated counterclockwise around the lock shaft, and the fixed metal plate is engaged with the socket portion, whereby the door is locked again with respect to the fixed frame. Then, the operating handle is pivotally pushed to the front concave portion of the housing body centering on the horizontal frame axis. In the terminal region of the push-in pivoting, the rear portion of the locking claw portion of the flash lock body and the rear wall of the housing body The cam slope of the part abuts. After the abutment, when the operating handle is pushed in again, the flash lock body is pushed by the cam inclined surface, and the locking claw portion enters the guiding slot. When the operating handle is correctly pushed into the front concave portion of the casing body and the guiding slot is opposed to the locking groove portion, the locking system is moved upward by the spring force of the spring member, and the locking claw portion and the locking groove portion are Re-engaged. The door lock device of the invention of the invention of claim 1 has an automatic locking function for locking the operating handle to the casing body by pushing the operating handle into the single body of the casing body, the automatic locking mechanism portion It is a lock unit embedded in the lower end of the operating handle, a plate inserted in the guide slot of the operating handle, 321489 8 201105850, a lock body, a locking groove portion of the rear wall portion of the casing body, and inserted in the guide slot hole a spring member between the bottom and the spring support portion of the flash lock body, an eccentric lock, a rear end portion of the rotor (4), a cam projection portion, and a cam slope portion of the wall portion of the housing body, and are inserted The driven cam hole of the intermediate portion of the flash lock body that drives the cam projection is formed into a rectangular shape having a large diameter and a horizontal diameter of the movable cam projection. Therefore, the number of parts of the automatic locking mechanism 4 is saved to the limit. The simplistic construction makes it possible to reduce the overall manufacturing cost of the device. Furthermore, since the main part of the automatic locking mechanism is built in the lower end of the operating handle 2, the length of the housing body can be shortened and the overall size of the housing can be made small. In addition to the effect of the item ^, the dimension of the longitudinal direction of the handle is set to be shorter than the dimension of the longitudinal direction of the front surface of the casing body. By using the dimensions of the longitudinal dimension of the two sides ==: in the buried state, in the concave portion of the front surface The lower end portion is formed so that the fingertip hooking portion for arranging the upper side of the fingertip insertion portion is connected to the i-lock early reading portion to be formed at the lower end portion of the handle, and the other finger of the same hand as the finger of the key is inserted. The aforementioned fingertip insertion=and hooking the weaving tip to the aforementioned fingertip insertion portion has the operational convenience of pulling the operation handle from the case body only by the early hand p. When approaching the lock unit embedding portion and when the operating handle does not have the fingertip insertion portion, the disc cylinder (8) (4) or the lock cylinder pln- loaded in the rotor of the lock unit must be pulled down to the front in the state where the key is rotated to the lock release position. The tumbier is engaged with the lock, and the handle is pivotally pulled out. However, the use of the keystroke by the 321489 9 201105850 reads the above-mentioned lock cylinder and the lock is too large, resulting in damage to the lock cylinder and the lock. The present invention holds the finger in the lock release position, hooks the fingertip hook portion located near the lock unit, and pivots the handle, so that the lock on the lock cylinder The contact portion of the grain contact and the lock itself cause an excessive burden. [Embodiment] In the embodiment of the present invention, the door 3 of the front opening 2 of the fixed frame 1 of the open storage box is attached to the fixed by a hinge key (not shown) on the right side of Fig. 5 Frame 1. The fixing opening 5 of the case body 4 is formed on the left end side of the door 3. The case main body 4 in which the fixing opening 5 is fitted from the front side of the door 3 abuts the outer peripheral flange portion 6 on the front surface of the door 3. The back side of the borrowing body 4 covers the U-shaped section 7 of the cross section, and the two tapping screws 46 penetrating through the retaining holes 8 of the ring body 7 are screwed into the back wall portion 9 of the casing body 4, and the spacer liner is interposed. 1〇Lock the ring body 7 to the back of the door 3. The longitudinally concave front side fixed to the casing body 4 of the door 3 in the above-described manner accommodates the operating handle 12 in an incapable manner, and the bearing cylinder portion 13 on the upper rear side of the casing body * receives the locking shaft 14 . In the phase groove (4), the (four) ring is received. Before the locking shaft 14, the end of the valley portion 15 is connected with the head 16 of the operating handle 12 by the horizontal _ 17, and the operating handle 12 = horizontal _17 is pulled out from the front concave portion η ( When the lower end of the operating handle is pulled out, the upper end of the operating handle 12 is centered on the horizontal pivot 17 and the shank 12 is obliquely protruded. Then, the wooden handle 12 obliquely from the shell body 4 is rotated around the locking shaft; 14 is rotated, and the fixing metal plate 321489 30 201105850 18 is detached from the fastening portion 19 of the fixed frame side, and the door 3 is released for fixing. Lock on the frame 1. The fixed metal plate 18 is fitted to the end shaft portion 2A after the lock shaft 14, and is fixed to the lock shaft 14 by the bolt 23 via the rotation angle restricting disk 21 and the ring 22. On the back side of the head portion 16 of the operating handle 12, inclined faces 24, 25 which are inclined opposite each other are formed. The end boss portion 15 is inserted into the expansion slot portion 26 extending through the slopes 24, 25 before the locking shaft 14. A spring plate 27 is fitted to the base portion of the front end boss portion π, and the spring plate 27 is compressed by the head 16 of the operating handle 12. In detail, the intersection ridges of the two inclined faces 24, 25 of the head yoke are crimped at the point P to the front surface of the spring plate 27, and when the operating handle 12 is correctly embedded in the front concave portion I of the body 4 The aforementioned crimping point p is located on the upper side of the horizontal axis l of the locking shaft 14. Therefore, the elastic reverse force of the spring plate 27 acts in the counterclockwise direction about the horizontal pivot 17 in Fig. 7, and the operating handle 12 is held in the buried state. The longitudinal dimension of the handle 12 is set to be shorter than the longitudinal dimension of the front concave portion 11 of the case body 4, and the longitudinal dimension difference between the two is used in the recessed state of the front handle u in the buried state of the handle 12. The lower end portion forms a fingertip insertion portion 28. A fingertip hooking portion 29 for partitioning the upper side of the fingertip insertion portion 28 is formed at the lower end portion of the operating handle 12. The lock embedding portion 3 is formed in the lower end portion of the operating handle 12 in the front-rear direction, and the guide hole 31 is formed in the vertical direction so as to be orthogonal to the rear end portion of the lock embedding portion 30. A plate-shaped latch member 32 is inserted into the guide slot 31 so as to be slidable in the up-down direction. The latch portion 34 is engaged with and disengaged from the lock groove portion 33 of the rear wall portion 9 of the case body 1 at the end portion of the latch body. At the end of the door 鍅# lock body 32, the lower end portion is formed by the above push spring 30 ov - the boring hole 37. The cylinder lock type fixed to the lock embedding portion 39 is formed in the rotor 39 of the lock unit 38 and the drive cam projection 4 is formed eccentrically from the center of rotation. ^There is a drive wheel projection 4G. The lock body 32 cam follower hole 37's.., Λ4 yellow size is formed to be larger than the diameter of the drive cam protrusion 40. The rear wall portion 9 of the case body 4 will The cam slope portion 42 of the lock body which is slidably engaged with the back portion 41 of the lock claw portion is formed at the position of the lock groove portion. When the rotor 39 is rotated by a predetermined angle (140 degrees in this embodiment) by the input key 44 inserted into the keyhole 43 of the rotor 39, the cam follower is pushed by the side portion of the drive cam projection 4G. The lower side portion 45 of the 37 retracts the latch body 32 into the guide slot 31 and disengages the pawl portion 34 of the latch body 32 from the lock groove portion 33 of the case body 4. After the operation handle 12 is unlocked in the above manner, the finger of the same hand other than the thumb and the index finger of the grasping key 44 (for example, the nameless member 45) is inserted into the fingertip insertion portion 38, and the fingertip is inserted. The operation finger 12 is pivotally pulled out from the case body 4 by hooking on the aforementioned fingertip insertion portion 29. The intersection ridge line of the aforementioned two inclined faces 24, 25 of the head 16 of the operating handle 12 and the crimping point ρ of the spring plate 27 are at the moment when the point ρ faces the lower side of the center axis B of the locking shaft 14 The direction of action of the elastic counter-pulling force of 27 is reversed, and the operating handle 12 is biased to the magazine plate 27 to protrude from the casing body 4 and rotate. Since the rotation operation of the key 44 can be performed by the same one-handed finger 12 321 489 201105850 and the pull-out operation of the operating handle 12, it is convenient in operation. When the key 44 rotor 39 is stopped, the locking claw portion 34 of the latch body 32 protrudes from the guide slot 31 by the longitudinal dimension of the cam follower hole 37 due to the biasing of the spring member 35 formed by the compression spring. The length is different from the size of the diameter of the drive cam protrusion 40. At this stage, since the operating handle 12 is in a state of being obliquely protruded, it is impossible to cause an unintended re-engagement of the claw portion 34 and the guide slot 31. After the door 3 is opened and the required work is completed, the door 3 is again locked, the reference operating handle 12 is rotated counterclockwise about the locking shaft 14, and the fixing metal plate 18 is engaged with the buckle portion 19, whereby the door 3 is opposite The fixed frame 1 is again locked. Then, the operating handle 12 is pivotally pushed to the front recess 11 of the case body 4 centering on the horizontal pivot 17, and in the terminal region of the pivoting push, the back portion 41 of the pawl portion 34 of the latch body 31 is The cam slope portion 42 of the rear wall portion 9 of the case body 4 is in contact with each other. After the abutment, when the operating handle 12 is pushed in again, the latch body 32 is pushed down by the cam ramp 42 and the pawl portion 34 I enters the guiding slot 31. When the operating handle 12 is correctly pushed into the front recess 11 of the casing body 4 and the locking groove portion 33 faces the guiding slot 31, the latch body 32 is moved upward by the spring member 35, The lock claw portion 34 is again engaged with the lock groove portion 33. That is, the locking of the operating handle 12 and the housing body 4 is automatically established. The back surface portion 41 of the lock claw portion 34 of the latch body 32 is formed as a curved surface. In the present embodiment, a cylinder lock of a known lock cylinder type in which the lock cylinder 48 is loaded in the rotor 39 is used. However, a lock cylinder type known cylinder lock can be used as the lock unit. 13 321489 201105850 [Simple description of the drawings] Fig. 1 shows a lock handle device of the present invention.
