As described above, in daily life, when unlocking and locking, people often need to insert the insertion end of the lock cylinder actuator (e.g., a key, a knob, etc.) into the lock cylinder by hand, then hold the holding end of the lock cylinder actuator and rotate the lock cylinder actuator, so as to drive the lock cylinder to rotate by using the lock cylinder actuator, thereby achieving the purpose of unlocking and locking (e.g., opening and locking a door). However, with the development of smart homes, a smart sticker lock is designed, which can rotate a key cylinder actuator by a motor, and for this purpose, a clamping device capable of clamping and inserting the key cylinder actuator into the key cylinder is required, however, whether the key cylinder actuator can be correctly positioned and fixed in the clamping device directly depends on whether the smart sticker lock can be operated smoothly. To this end, the present invention proposes an alignment sleeve configured for positioning a lock cylinder actuator in a clamping device. As will be described in further detail below, after the alignment sleeve positions the cylinder actuator in the clamp device, an operator may secure the cylinder actuator in the clamp device by screwing a fastening stud on the clamp device. The properly secured together clamp and cylinder actuator can then be used to assemble the smart sticker. Referring to fig. 1, the alignment sleeve 100 according to the present invention includes a first end 110 intended to face the clamping device 200 and a second end 120 intended to face away from the clamping device 200, wherein a distance separating the first end 110 and the second end 120 may be referred to as a thickness of the alignment sleeve 100, in other words, the first end 110 and the second end 120 define the thickness of the alignment sleeve 100. It should be noted here that the direction denoted by reference numeral TT 'in the drawings, that is, the thickness direction TT' means a direction in which the thickness is present as a name implies. With continued reference to fig. 1, the alignment sleeve 100 is provided with a groove 130, the groove 130 extends from the first end 110 toward the second end 120 (in other words, extends toward the inside of the alignment sleeve 100 along the thickness direction TT') to a groove bottom wall 132 of the groove 130, and the groove 130 is configured to engage with the clamping device 200. Further, the alignment sleeve 100 is further provided with a through hole 140 extending from the second end 120 to the groove bottom wall 132 of the groove 130, and the through hole 140 is configured to engage with the lock cylinder.

According to the above technical solution, as shown in fig. 3, when the alignment sleeve 100 is used, the through hole 140 is firstly used for clamping the lock cylinder, then the insertion end 320 of the lock cylinder actuator 300 is inserted into the lock cylinder, and then the groove 130 is used for clamping the clamping device 200, so that the purpose of positioning the lock cylinder actuator 300 in the clamping device 200 through the alignment sleeve 100 is achieved, and after that, the clamping device 200 and the lock cylinder actuator 300 can be fixed together by using a fastening device (such as a fastening bolt 250 described below) for subsequent assembling of the intelligent patch lock.

Referring now to fig. 2-4, a clamping device 200 to which the alignment sleeve 100 is applicable will be described in detail, as shown in fig. 2 and 3, the clamping device 200 having a receiving aperture 210 disposed therein, the receiving aperture 210 extending along a thickness direction TT' as shown and configured to receive a gripping end 310 of a cylinder actuator 300. The holding device 200 further has: a plurality of threaded holes 220 (six threaded holes 220 are included in the example shown in the figures, three on each side of the receiving hole 210) provided in the side wall of the clamping device 200 and extending from the outer surface thereof into the receiving hole 210; and a plurality of fastening studs 250 (or screws or the like) engaged with the plurality of threaded holes 220, wherein the plurality of fastening studs 250 are adapted to be screwed into the receiving holes 210 from outside the clamping device 200 so as to clamp the holding end 310 of the cylinder actuator 300, as best shown in fig. 3 and 4. In addition, in the example shown in the figures, the gripping device 200 also has a pair of snap-in planes 230, 240 provided on its outer surface, in particular, the snap-in planes 230, 240 are parallel to each other. Further, as shown, the snap- fit planes 230, 240 are provided on a pair of bosses 260, 270 protruding in opposite directions from the outer surface of the clip device 200. In particular, the plurality of threaded holes 220 extend from the snap flats 230, 240 into the receiving bore 210. Therefore, as described above, the through hole 140 may be used to first engage the lock cylinder, then the insertion end 320 of the lock cylinder actuator 300 is inserted into the lock cylinder, and then the groove 130 is used to engage the clamping device 200, at which time the holding end 310 of the lock cylinder actuator 300 is in the receiving hole 210 of the clamping device 200, thereby positioning the holding end 310 of the lock cylinder actuator 300 in the receiving hole 210 of the clamping device 200 by using the alignment sleeve 100, and after that, the fastening stud 250 may be screwed into the receiving hole 210, so as to hold the holding end 310 of the lock cylinder actuator 300 by using the fastening stud 250, and thereby fixing the clamping device 200 and the lock cylinder actuator 300 together for subsequent assembly of the smart sticker.

Alternatively, as shown in fig. 1, 3 and 4, the groove 130 has a pair of flat groove side walls 131, 133 connected by a groove bottom wall 132, the groove side walls 131, 133 being configured for engaging the holding device 200, in particular, being configured for engaging the engagement planes 230, 240 of the holding device 200.

Alternatively, as shown in fig. 1, 3 and 4, the groove sidewalls 131, 133 are parallel to each other so as to engage the mutually parallel engagement planes 230, 240.

Optionally, the groove sidewalls 131, 133 extend through the alignment sleeve 100 in a direction perpendicular to the thickness direction TT '(the width direction WW' shown in the figure). In this manner, the channel 130 leaves an offset space 134 (shown in fig. 3 and 4) for the clamp device 200 in the direction perpendicular to the thickness direction TT ', and due to the offset space 134, the clamp device 200 can translate in the channel 130 in the direction perpendicular to the thickness direction TT', which enables the alignment sleeve 100 to position it in the clamp device 200 with respect to various types of existing cylinder actuators, such as cylinder actuators having their gripping ends offset with respect to the insertion end. That is, the alignment sleeve 100 according to the present disclosure is suitable for positioning various types of cylinder actuators in the clamping device 200 without the need to customize the alignment sleeve for a particular type of cylinder actuator (e.g., a key, a knob, etc.), which greatly widens the application range and application of the present alignment sleeve.

Optionally, referring to fig. 1, 3 and 5, the alignment sleeve 100 further has an adhesive layer 150 disposed on the second end 120, wherein the adhesive layer 150 does not cover the through hole 140. Thus, after the key cylinder is snapped by the through hole 140, the alignment sleeve 100 can be adhesively secured in place by the adhesive layer 150 to facilitate subsequent operations of snapping the clamp 200 and securing the key cylinder actuator 300.

Further optionally, referring to fig. 5, the second end portion 120 has an exposed area 121 not covered by the adhesive layer 150, wherein the exposed area 121 is disposed around the through hole 140. In this way, the adhesive layer 150 can be prevented from adhering to the lock cylinder to affect subsequent operations.

Preferred but non-limiting embodiments of the register sleeve according to the invention are described in detail above with the aid of the accompanying drawings. Modifications and additions to the techniques and structures, without departing from the scope and spirit of the disclosure as set forth in the following claims, are deemed to be within the scope of the invention.
