Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The embodiment discloses a simple door lock handle, as shown in fig. 1-5, comprising an inner handle 1, an outer handle 2, and a hollow square rod 3, wherein the hollow square rod 3 is used for being in transmission connection with a lock body (not shown in the figure) in a door, and the connection between the hollow square rod and the lock body is conventional in the art, and the utility model does not describe specific structures in detail. The utility model is characterized in that the two ends of the hollow square rod 3 are respectively provided with a connecting part A301 and a connecting part B302, the connecting part A301 is of a square structure, the middle part of the connecting part A301 is provided with a round hole, the connecting part B302 is of a round structure, the middle part of the connecting part B302 is provided with a square hole 9, the inner handle 1 is provided with a square groove 101 matched with the connecting part A301, and the outer handle 2 is provided with a round groove 201 matched with the connecting part B302; thus, when the inner handle 1 is rotated, the hollow square bar 3 is rotated in synchronization with the square groove 101 and the connection portion a301, and when the outer handle is rotated, the hollow square bar 3 is not rotated when the outer handle is directly rotated because the connection portion B302 and the circular groove 201 cannot be circumferentially fixed.
Further, a sliding shaft 4 is slidably arranged in the inner handle 1, a driving piece 5 is arranged on the sliding shaft 4, and referring to fig. 2-4, a protruding part 6 is arranged on the driving piece 5, an opening 7 is arranged on the inner handle 1, and the protruding part 6 stretches into the opening 7 and slides in the opening; the driving member 5 and the sliding shaft are fixed, the protruding portion 6 is preferably a set screw, and the set screw is fixed with the driving member 5 by means of threads, and the advantage of selecting the set screw is that the protruding portion 6 can be screwed into the driving member 5 after the door lock handle is mounted on a door, so that the relative positions of the sliding shaft 4, the driving member 5 and the protruding portion 6 can be adjusted, and the door lock handle can be conveniently adapted to doors with different thicknesses. In particular, when in use, the purpose of controlling the movement of the sliding shaft 4 can be achieved by manually controlling the movement of the protruding part 6 in the opening 7. Further, the sliding shaft 4 penetrates through the hollow square rod 3 and extends into the outer handle 2, the transmission square rod 8 which is slidably arranged in the outer handle 2 is axially fixed with the sliding shaft 4 and can rotate relatively, the concrete connection structure of the sliding shaft 4 and the transmission square rod 8 is that an annular groove 401 is formed in one end of the sliding shaft 4 which is matched with the transmission square rod 8, a socket 801 is formed in the transmission square rod 8, a bayonet lock 802 is arranged in the socket 801 in a protruding mode, the bayonet lock 802 is matched with the annular groove 401, therefore, the sliding shaft 4 moves axially, the transmission square rod 8 moves axially together due to the matching of the annular groove 401 and the bayonet lock 802, and when the transmission square rod 8 rotates, the sliding shaft 4 cannot rotate due to the fact that the bayonet lock 802 can move circumferentially in the annular groove 401. By the above structure, when the sliding shaft 4 moves axially, the square transmission rod 8 with the square end part is driven to move in or out of the square hole 9. The square hole 9 is a hole in the middle of the connecting part B302, and a square connecting hole 15 is arranged in the outer handle 2, and the connecting hole 15 is matched with the transmission square rod 8. Therefore, after the transmission square rod 8 moves into the square hole 9, the hollow square rod 3 can be driven to rotate by the transmission square rod 8 by rotating the outer handle 2, so that the control of the door inner lock body is realized. When the transmission square rod 8 moves out of the square hole 9, the outer rotating handle only idles, the hollow square rod 3 cannot be driven to rotate, and unlocking cannot be performed naturally.
Further, the present embodiment further includes an end cap 10 mounted on the door, and the end caps 10 are provided in two, and the two end caps 10 are respectively used for supporting the rotation of the inner handle and the outer handle.
Further, referring to fig. 4-5, a first positioning hole 11 and a second positioning hole 12 are formed in the transmission square bar 8, an abutting spring 13 and a small steel ball 14 are arranged in the outer handle 2, and the small steel ball 14 is clamped into the first positioning hole 11 or the second positioning hole 12 under the action of the abutting spring 13. Wherein, the position of first locating hole 11 corresponds this transmission square bar 8 and does not cooperate with square hole 9 position, and the position of second locating hole 12 corresponds transmission square bar 8 and square hole 9 cooperation position, and above-mentioned structure plays the effect of location after transmission square bar 8 removes, prevents that transmission square bar from taking place by oneself under the condition of not receiving external force.
Further, referring to fig. 2-3, an unlocking small hole 16 is provided on the outer handle 2, and the unlocking small hole 16 communicates the driving square bar 8 with the outside of the outer handle 2. In emergency, the door needs to be opened outside the door, so that an unlocking small hole 16 is formed in the outer handle, small rod-shaped objects like small nails can extend into the unlocking small hole 16, the driving square rod 8 is pushed into the square hole 9, and the hollow square rod 3 can be driven to rotate after the outer handle 2 is rotated, so that the door can be opened in emergency.
Referring to fig. 2-3, when the utility model is in use, the rotation of the inner handle 1 can drive the hollow square rod 3 to rotate, and simultaneously the inner handle 1 can realize locking and unlocking by controlling the movement of the protruding part 6, when the protruding part 6 is positioned in the position of fig. 2, the locking state is the locking state, and when the protruding part 6 is positioned in the position of fig. 3, the outer handle 2 is rotated to idle and can not open the door, and when the protruding part 6 is positioned in the position of fig. 3, the unlocking state is the unlocking state, and when the outer handle 2 is rotated, the door can be opened.
