Compared with a door lock reset transmission mechanism on the market, the spiral spring reset mechanism has the advantages of simplifying parts, saving cost, reducing sizes, being convenient to assemble and low in production cost and the like.

Description

A kind of spiral spring resetting-mechanism

Technical field

The utility model relates to a kind of door lock, particularly a kind of door lock spiral spring resetting-mechanism.

Background technology

Door lock kind in the market is varied, and the mechanical drive mode of door lock is also varied, and the resetting structure kind of handle is also more and more, and most resetting structure all is the architectural feature of utilizing spring, for example spiral spring and extension spring; Wherein spiral spring is generally annular, utilizes the characteristic of the centripetal torsion of spiral spring to realize that handle resets.

The utility model content

The purpose of this utility model provides a kind of novel door lock resetting-mechanism, adopt the spiral spring principle, each design of part that brand-new design cooperates with spiral spring utilizes the feature of parts itself, reaches more desirable technique effect, compare with the transmission mechanism that resets of the door lock on the market, have and simplified part, save cost, reduce volume, easy to assembly, the characteristics such as cost of production is low.

In order to achieve the above object, the technical solution of the utility model is as follows:

A kind of spiral spring resetting-mechanism, comprise: handle module 1, locking face 2, reseting module 3 is characterized in that described reseting module 3 forms three's concentric fits by upper resetting block 31, lower resetting block 32, the spiral spring 33 that resets, upper resetting block 31 is fixed on the locking face 2 that locking face 2 is forever static relatively, lower resetting block 32 is sleeved on the reference column 21, and the spiral spring 33 that resets is sleeved on the lower resetting block 32, and reset spiral spring 33 and lower resetting block 32 can be around reference column 21 rotations.

A kind of spiral spring resetting-mechanism can also be to comprise: handle module 1, locking face 2, reseting module 3, clutch 4; It is characterized in that described reseting module 3 is comprised of upper resetting block 31, lower resetting block 32, the spiral spring 33 that resets, three's concentric fits, upper resetting block 31 is fixed on the locking face 2 that locking face 2 is forever static relatively, lower resetting block 32 is sleeved on the reference column 21, the spiral spring 33 that resets is sleeved on the lower resetting block 32, can be around reference column 21 rotations on reset spiral spring 33 and the lower resetting block 32; The first flange 311 is arranged on the upper resetting block 31, the second flange 321 is arranged on the lower resetting block 32, the first flange 311 and the second flange 321 the two concentric fits, reset under the reset condition both sides of spiral spring 33 are installed on the both sides of the first flange 311 and the second flange 321 simultaneously, under the motion state, the second flange 321 drives the spiral spring 33 that resets and rotates with respect to the first flange 311 around reference column 21.

Description of drawings

Fig. 1 is explosive view of the present utility model;

Fig. 2 is the utility model front view;

Fig. 3 is the A-A generalized section of Fig. 2, shows each component assemble relation;

Fig. 4 be under the inactive state special show reseting module 3 and turn-take 12 and clutch 4 between movement relation;

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

Such as Fig. 1, Fig. 2, each figure shown in Figure 3 demonstrates the position relationship of each parts, handle 11 and the 12 formation handle modules 1 secured together of turn-taking; Reseting module 3 is comprised of upper resetting block 31, lower resetting block 32, the spiral spring 33 that resets, and reference column 21 is arranged on the locking face 2, and the lower resetting block 32 of reseting module 3 is sleeved on the reference column 21, and the spiral spring 33 that resets is sleeved on the lower resetting block 32, and the two can be around reference column 21 rotations; The first flange 311 is arranged on the upper resetting block 31, the second flange 321 is arranged on the lower resetting block 32, the first flange 311 and the second flange 321 the two concentric fits, reset under the reset condition both sides of spiral spring 33 are installed on the both sides of the first flange 311 and the second flange 321 simultaneously, under the motion state, the second flange 321 drives the spiral spring 33 that resets and rotates with respect to the first flange 311 around reference column 21; Upper resetting block 31 is fixed on the locking face 2 that locking face 2 is forever static relatively; Turn-taking has rib 121 on 12, and block 41 is arranged on the clutch 4, and block 41 offsets with rib 121; Lower resetting block 32 12 has tooth-shape structure with turn-taking, and the two drives mutually by the gear engagement.

Be illustrated in figure 4 as under the inactive state special show reseting module 3 and turn-take 12 and clutch 4 between movement relation; When handle module 1 is turned clockwise by external force, because the rib 121 of turn-taking on 12 offsets with block 41 on the clutch 4, so clutch 4 turns clockwise with handle module 1 together, reach the purpose of output handle torsion; Meanwhile, handle module 1 is when turning clockwise, the gear on 12 of turn-taking drives lower resetting block 32 by the gear engagement and does and rotate counterclockwise, because upper resetting block 31 is fixed on the locking face 2 and can't rotates, and the limit of the spiral spring 33 that resets is installed on the second flange 321 of the first flange 311 of resetting block 31 and lower resetting block 32, instantly resetting block 32 is followed handle module 1 when rotating together, the one side that can only drive the spiral spring 33 that resets rotates together, thereby make the spiral spring 33 that resets produce reset force, as shown in Figure 5; When the external force disappearance from handle module 1, the restoring force of the spiral spring 33 that resets forces reverse handle module 1 turning anticlockwise that drives of lower resetting block 32 clockwise revolutions to reach the purpose that resets.

In like manner, when handle module 1 is subject to external force and is rotated counterclockwise, 12 do not offset with clutch 4 owing to turn-take, turn-take and 12 can't be with dynamic clutch 4 to rotate together, handle torsion can't be exported, but the principle of reseting module 3 and the mutual driving between 12 of turn-taking is the same that the reset response that handle module 1 is produced also is the same, no matter how handle rotates in other words, and reseting module 3 can both reset handle.
