Description

New door lock mechanism

Technical field

The utility model relates to a kind of latch mechanism.

Background technology

At present, the electronic lock on the market is made up of front handlebar, panel (band circuit board), axis, special electronic lock lock body and back handle, the panel parts such as (charged pool boxes) of door lock, and special-purpose lock body the inside all has electric machine, can not be compatible with common lock body; And circuit part is installed in the mechanical part, and failure-frequency is high, the detection maintenance difficulty is big; The axis that connects front and back panel also is the front and back that are contained in lock body by two square bars respectively; Lean on circuit part in the lock body to assign to accomplish the purpose that front handlebar idle running and real-turn function (it is to accomplish this function by the hardware unit of circuit board that the part door lock is also arranged) reach the switch door; If circuit part breaks down or installs incompleteness; Mechanical part will receive directly to influence, even can't accomplish the function of switch door separately; And standard machinery lock can't reach an axis at all and makes front handlebar idle running and real-turn function freely.

Therefore, prior art haves much room for improvement.

The utility model content

The technical problem that the utility model will solve is to overcome deficiency of the prior art, proposes a kind of new door lock mechanism, solves existing two axis complex structures that square bar connects into, and trouble is installed; Circuit and mechanical mixture device break down easily, and can't independently accomplish problems such as door interlock switch function by folk prescription.

Be to realize above-mentioned purpose, the technical scheme of the utility model is: a kind of new door lock mechanism, be made up of Door lock casing, door lock handle, door lock axis and lock body; Said door lock axis connects door lock handle and lock body, it is characterized in that, also comprises kelly, kelly base, spring, brace; Said kelly base is arranged in the mesopore of door lock handle, and said kelly base bottom is a cylindrical bore, loading spring in the hole; Said kelly one end is a cylinder; The other end is a square body, and two ends are connected by the square body in the middle of the kelly, and the column part of said kelly injects the endoporus in the kelly base; Said brace top is provided with square hole, the square column part of the square hole fastening kelly of said brace.

Said door lock axis is a square body, and an end is provided with hollow, and said door lock axis hollow end is entangled the square column part of kelly, and said door lock axis is provided with base plate, through being arranged at the fixing door lock axis of screw on the base plate.

Also include the key control strip, said key control strip and Door lock casing are parastate under the situation of not opening the door.

The outer setting of said kelly base has square hole.

The beneficial effect of the utility model: the utility model is provided with the kelly base at the door lock handle mesopore, and kelly base loading spring is with the endoporus in the column part reeve kelly base of kelly; With the square column part of brace square hole fastening kelly, then the axis hollow parts is entangled kelly square column part again, the square body in the middle of the kelly embeds the interior square hole of kelly base; Cause handle to connect by axis always, make axis drive lock body, reach the purpose of opening the door to lock body; The utility model adopts an axis; Simple in structure, stable performance, easy for installation.

Below will combine accompanying drawing and embodiment, the utility model will be carried out comparatively detailed explanation.

Description of drawings

Fig. 1 is the STRUCTURE DECOMPOSITION sketch map of the utility model.

Among the figure: 1. Door lock casing, 2. door lock handle, 3. door lock axis, 4. lock body, 5. kelly, 6. kelly base, 7. spring, 8. brace, 9, base plate, 10. screw, 11, key control strip.

The specific embodiment

As shown in Figure 1, a kind of new door lock mechanism is made up of Door lock casing 1, door lock handle 2, door lock axis 3 and lock body 4; Said door lock axis 3 connects door lock handle 2 and lock body 4, it is characterized in that, also comprises kelly 5, kelly base 6, spring 7, brace 8; Said kelly base 6 is arranged in the mesopore of door lock handle 2, and said kelly base 6 bottoms are cylindrical bores, and loading spring 7 in the hole; Said kelly 5 one ends are cylinder; The other end is a square body, and two ends are connected by the square body in the middle of the kelly, and the column part of said kelly 5 injects the endoporus in the kelly base 6; Said brace 8 tops are provided with square hole, the square column part of the square hole fastening kelly 5 of said brace 8.

Said door lock axis 3 is a square body, and an end is provided with hollow, and said door lock axis 3 hollow end are entangled the square column part of kelly 5, and said door lock axis 3 is provided with base plate 9, through being arranged at the fixing door lock axis 3 of screw 10 on the base plate 9.

Also include key control strip 11, said key control strip 11 is parastate with Door lock casing 1 under the situation of not opening the door.

The outer setting of said kelly base 6 has square hole.

In the mesopore of door lock handle, add the kelly base, kelly base the inside is put spring into, injects kelly again; Control strip on the upper cover, with middle shaft hollow connects kelly then, under the state that does not open the door; The control strip and the Door lock casing of mechanical key are parastate, and kelly base and kelly separate under the effect of base inner spring; The outside handle can't drive the square column of kelly, idling conditions occur, can not open the door; When opening the door, when revolving with key when turning 90 degrees, the control strip of key will with lock panel in vertical state; With brace jack-up, under the effect of a middle fulcrum, kelly and spring are depressed; Make the middle square body of kelly embed the interior square hole of kelly base, kelly base and kelly are connected, the square column of kelly partly drives door lock axis and lock body; Cause door lock handle to connect always, make the door lock axis drive lock body, reach the purpose of opening the door to the door lock axis.

The utility model is provided with the kelly base at the door lock handle mesopore, and kelly base loading spring is with the endoporus in the column part reeve kelly base of kelly; With the square column part of brace square hole fastening kelly, then the axis hollow parts is entangled kelly square column part again, the square body in the middle of the kelly embeds the interior square hole of kelly base; Cause handle to connect by axis always, make axis drive lock body, reach the purpose of opening the door to lock body; The utility model adopts an axis; Simple in structure, stable performance, easy for installation.

Above embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that the common engineers and technicians in this area make the technical scheme of the utility model all should fall in the protection domain that claims of the utility model confirm.

The utility model does not relate to all identical with the prior art prior art that maybe can adopt of part to be realized.
