Detailed Description
The present utility model is described in further detail below with reference to the drawings to enable those skilled in the art to practice the utility model by referring to the description.
As shown in fig. 1, 2 and 3, the door lock handle quick-mounting structure of the utility model comprises a square rod 3 penetrating through a door plate 2, and two ends of the square rod 3 can be matched with a mounting handle 1. In order to realize quick assembly and disassembly of the handle 1 without the help of special tools, the end 31 of the square rod 3 is provided with an inward concave clamping groove 33 along the circumferential direction. Meanwhile, a protruding clamping cylinder 4 is arranged at the front end of the handle 1, and an elastic clamping component 5 is arranged on the cylinder wall of the clamping cylinder 4. When the end 31 of the square rod 3 is clamped into the clamping cylinder 4, the elastic clamping component 5 can be clamped against the inner concave clamping groove 33, so that the handle 1 and the square rod 3 are fixedly connected together; when the square rod 3 is required to be detached from the handle 1, the elastic clamping and supporting component 5 is only required to be operated, so that the elastic clamping and supporting component 5 is separated from the clamping and supporting of the concave clamping groove 33. In the door lock handle fast-assembling structure, the end part of the square rod 3 is provided with the concave clamping groove 33, and the elastic clamping and abutting component 5 correspondingly matched with the concave clamping groove 33 is arranged on the handle, so that the clamping and abutting and the separating of the elastic clamping and abutting component 5 and the concave clamping groove 33 can be realized without a special tool, namely, the quick installation and the separation of the handle 1 and the square rod 3 are realized, and the on-site operation is greatly facilitated.
In the door lock handle quick-mounting structure, the shape of the cylinder inner cavity of the clamping cylinder 4 is correspondingly matched with the shape of the end 31 of the square rod 3, and in order to enhance the consistency of rotation of the handle 1 and the square rod 3 when the handle is forced to rotate, a plurality of longitudinal sliding grooves 32 are formed at the tail end of the square rod 3, and corresponding longitudinal clamping columns 41 are formed on the inner wall of the clamping cylinder 4, so that when the end 31 of the square rod 3 is clamped into the clamping cylinder 4, the longitudinal clamping columns 41 are correspondingly clamped into the longitudinal sliding grooves 32, and the handle 1 and the square rod 3 are ensured to synchronously rotate under the condition of external force.
In the door lock handle quick-mounting structure of the present utility model, the elastic clamping component 5 may specifically include an elastic clamping bead 51 and an elastic sliding sleeve 52. The elastic clamping beads 51 are movably clamped in the unidirectional clamping holes 42 formed in the clamping cylinder 4 (the unidirectional clamping holes 42 are conical holes formed in the wall of the clamping cylinder 4 and gradually shrink from the outer wall of the clamping cylinder 4 to the inner wall, the diameter of the holes formed in the inner wall of the clamping cylinder 4 is smaller than that of the elastic clamping beads 51, the diameter of the holes formed in the outer wall of the clamping cylinder 4 is larger than that of the elastic clamping beads 51, the elastic clamping beads 51 can move in the conical holes, and when the elastic clamping beads 51 move to the small diameter end of the inner wall of the clamping cylinder 4, the front sides of the elastic clamping beads 51 can partially protrude out of the conical holes.
The elastic sliding sleeve 52 is sleeved on the outer edge of the clamping cylinder 4 in a sliding way. When the elastic sliding sleeve 52 is pushed by an external force and is located at the front end position of the clamping cylinder 4, the elastic sliding sleeve 52 abuts against the back side of the elastic clamping bead 51 (i.e. the side of the elastic clamping bead 51 corresponding to the outer wall of the clamping cylinder 4) so that the elastic clamping bead 51 is fixed in the unidirectional clamping hole 42, and the front side of the elastic clamping bead 51 (i.e. the side of the elastic clamping bead 51 corresponding to the inner wall of the clamping cylinder 4) protrudes out of the unidirectional clamping hole 42 and is clamped in the concave clamping groove 33. That is, when the back side of the elastic clamping bead 51 is pressed against the one-way clamping hole 42, the elastic clamping bead 51 moves toward the inner wall of the clamping cylinder 4 in the one-way clamping hole 42, and the front side of the elastic clamping bead 51 protrudes out of the one-way clamping hole 42 and is clamped against the concave clamping groove 33 (as shown in fig. 1) along with the pressing, and the handle 1 is firmly mounted at the end of the square rod 3.
Conversely, if the elastic clamping bead 51 is to slide off the one-way clamping hole 42, so as to eliminate the abutment of the elastic clamping bead 51 against the concave clamping groove 33, the abutment force continuously applied to the elastic clamping bead 51 needs to be removed. Then, the elastic sliding sleeve 52 is driven by an external force to slide to the rear end position of the locking cylinder 4 (as shown in fig. 2), the elastic clamping bead 51 slides off the unidirectional clamping hole 42 due to being separated from the abutment of the elastic sliding sleeve 52, and the front side of the elastic clamping bead 51 is separated from the concave clamping groove 33, so that the handle 1 can be pulled away from the end of the square rod 3.
The above-mentioned external force that keeps the elastic sliding sleeve 52 against the elastic clamping bead 51 can be achieved by arranging the spring sleeve 6 at the root of the clamping cylinder 4, that is, the end of the spring sleeve 6 is fixed with the root of the clamping cylinder 4, the front end of the spring sleeve 6 can move freely, and the front end of the spring sleeve 6 abuts against the rear end of the elastic sliding sleeve 52, so that the elastic sliding sleeve 52 is positioned at the front end of the clamping cylinder 4 under the action of the continuous elastic abutting of the spring sleeve 6. When the pushing external force applied to the elastic sliding sleeve 52 to the rear end of the clamping cylinder 4 is greater than the pushing elastic force of the spring sleeve 6, the elastic sliding sleeve 52 can slide to the rear end of the clamping cylinder 4.
In addition, during the sliding of the elastic sliding sleeve 52 toward the front end of the locking cylinder 4, the elastic sliding sleeve 52 is continuously abutted against the elastic locking bead 51 and can move the elastic locking bead 51 along the unidirectional locking hole 42, so the front end inner wall 53 of the elastic sliding sleeve 52 is processed into a flared cylinder shape that gradually expands, and the rear end inner wall of the elastic sliding sleeve 52 is a straight cylinder shape. Thus, when the elastic sliding sleeve 52 is pushed toward the front end of the locking cylinder 4 by an external force (for example, the spring force of the spring housing 5 against the elastic sliding sleeve 52), the outer edge of the horn-shaped inner wall of the front end of the elastic sliding sleeve 52 contacts the back side of the elastic locking bead 51 (as shown in fig. 2), and starts to exert a pressing force against the elastic locking bead 51; with the continuous forward movement of the elastic sliding sleeve 52 until the inner edge of the horn-shaped inner wall at the front end of the elastic sliding sleeve 52 contacts the back side of the elastic clamping bead 51 (as shown in fig. 1, the elastic clamping bead 51 is gradually pushed into the unidirectional clamping hole 42 to be clamped against the concave clamping groove 33. Conversely, when the elastic sliding sleeve 52 receives a pushing external force to the rear end of the locking cylinder 4, the elastic sliding sleeve 52 moves to the rear end of the locking cylinder 4, the movement track of the elastic clamping bead 51 is opposite to the above, and the elastic clamping bead 51 is separated from the concave clamping groove 33 and slides down along the unidirectional clamping hole 42. By adjusting the sizes of the horn-shaped inner wall at the front end and the straight-shaped inner wall at the rear end of the elastic sliding sleeve 52, it is ensured that the elastic clamping bead 51 is separated from and abuts against the concave clamping groove 33 to separate the handle 1 from the square rod 3, and that the elastic clamping bead 51 is separated from and abuts against the concave clamping groove 33 to firmly connect the handle 1 with the square rod 3. In addition, a snap ring 43 may be disposed at the front end of the unidirectional clamping hole 42 of the clamping cylinder 4 to prevent the elastic clamping bead 51 from coming out from between the front end horn-shaped inner wall of the elastic sliding sleeve 52 and the outer wall of the clamping cylinder 4, and also prevent the elastic sliding sleeve 52 from coming out from the front end of the clamping cylinder 4.
Although embodiments of the present utility model have been disclosed above, it is not limited to the details and embodiments shown and described, it is well suited to various fields of use for which the utility model would be readily apparent to those skilled in the art, and accordingly, the utility model is not limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
