Description

Technical Field

[0001] This utility model relates to an anti-theft device, specifically a pull-cord padlock. Background Technology

[0002] Padlock tags are anti-theft devices that are suspended from merchandise and used in shopping malls, supermarkets, department stores, convenience stores, and other locations to protect bags, clothing, and other similar items. Since customers often misplace merchandise after trying it out, causing items to stray from their original display positions, a pull-cord box can be added to the padlock to facilitate staff inventory management and reduce workload. However, conventional pull-cord boxes have a short release length, insufficient to meet the needs of normal customer use. Furthermore, the release length of the pull-cord box is related to its size; extending the release length would significantly increase the box's volume, thus affecting the proper display of the merchandise. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide a pull-cord padlock that has the characteristics of simple structure and convenient use.

[0004] The technical solution of this utility model is:

[0005] A pull-cord padlock, characterized in that it includes a base and a padlock; the base is provided with a main pull cord, and the padlock is provided with a secondary pull cord, the pull cords of which are connected.

[0006] The padlock is equipped with a lanyard for connecting the plug, a socket for inserting the plug, and a lock cylinder structure for locking the plug.

[0007] The main cable puller includes a main winding reel rotatably positioned in the base, a pull cable wound on the main winding reel, and a main coil spring that drives the main winding reel to rotate to tighten the pull cable.

[0008] The auxiliary cable puller includes an auxiliary winding reel rotatably positioned in the padlock, a pull cable wound on the auxiliary winding reel, and an auxiliary coil spring that drives the auxiliary winding reel to rotate and tighten the pull cable.

[0009] The auxiliary cable puller also includes a limiting member that is slidably positioned on the padlock, a notch provided on the edge of the auxiliary winding reel, and a limiting member spring that allows the limiting member to be inserted into the notch to prevent the auxiliary winding reel from rotating.

[0010] The lock cylinder structure includes a plug lock hole on the plug, a padlock pin, and a padlock spring that allows the padlock pin to be inserted into the plug.

[0011] The beneficial effects of this utility model are:

[0012] The base and padlock of this utility model are connected by a pull cord; the base is a fixed component that can be installed on a flat or curved surface in the display area, while the padlock is a movable component that is hung on bags, clothes, and other merchandise; both the base and the padlock have built-in pull cord devices that can release and retract the pull cord. The two pull cord devices use the same pull cord, which can greatly extend the pull cord length without increasing the size of the pull cord devices, thus meeting the needs of customers for trying on and using the products, and making it very convenient to use.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0031] like Figure 1 , Figure 2 As shown, the pull-cord padlock includes a base 1, a padlock 2, and a pull cord 3.

[0032] The base is fixed to the display area and has a built-in main pull cord. The padlock is suspended from the merchandise and has a built-in auxiliary pull cord. The pull cord of the main pull cord is connected to the pull cord of the auxiliary pull cord, and the main pull cord and auxiliary pull cord use the same pull cord. The main pull cord and auxiliary pull cord are respectively located at both ends of the pull cord.

[0033] like Figures 3 to 6 As shown, the base includes a base shell and a main cable puller. The base shell consists of a base top cover 1-1 and a base bottom plate 1-2.

[0034] The main cable puller includes a main winding reel 4.1, a main coil spring 4.2, and a cable. The main winding reel is rotatably positioned in the base housing via a bearing 4.1.1, and the main coil spring is used to drive the main winding reel to rotate to tighten the cable.

[0035] The base can be attached to the display area surface with double-sided tape. The base shell is also provided with ear stands 1.7 on both sides, and the ear stands are provided with fixing holes 1.7.1 for installing screws.

[0036] like Figures 7 to 11 As shown, the padlock includes a padlock housing, a lanyard 2.1, a plug 2.2, a lock cylinder structure, and a secondary pull cord device.

[0037] The padlock housing consists of two padlock halves 2-1. The padlock main board, lock cylinder structure, and auxiliary pull cable are located inside the padlock housing. The padlock housing has a socket 2.9. One end of the lanyard is connected to the padlock housing, and a plug for inserting into the socket is located at the other end of the lanyard.

[0038] The auxiliary cable puller includes an auxiliary winding reel 4.3, a pull cable, an auxiliary coil spring 4.4, a limiting member 4.5, and a limiting member spring 4.6. The auxiliary winding reel is rotatably positioned in the padlock housing. One end of the pull cable is wound around the auxiliary winding reel, and the other end extends out of the padlock housing and connects to the base. The auxiliary coil spring is used to drive the auxiliary winding reel to rotate to tighten the pull cable.

[0039] like Figure 14 As shown, the secondary winding reel has several notches 4.3.1 along its edge. The limiting member is slidably positioned on the side of the padlock housing, as shown... Figure 13 As shown, the limiting member has a baffle 4.5.1 that extends into the padlock housing. The limiting member spring is used to push the limiting member towards the secondary winding reel, so that the baffle of the limiting member inserts into the notch to prevent the secondary winding reel from rotating.

[0040] The lock cylinder structure includes a padlock pin 2.3 and a padlock spring 2.4. For example... Figure 12 As shown, the plug has a plug locking hole 2.2.1. The padlock pin is slidably positioned in the padlock housing, and the padlock spring is used to push the padlock pin into the plug locking hole to lock the plug. When the lock cylinder structure is locked, the plug is locked by the padlock pin and cannot be pulled out.

[0041] The pull line is also equipped with a silicone sleeve 4-1, which is located between the main puller and the auxiliary puller. Changing the position of the silicone sleeve allows for easy adjustment of the pull length of the main puller.

[0042] The method of using this utility model is as follows:

[0043] 1. Attach the base to the display area tabletop using traceless double-sided tape, or you can choose to reinforce it with screws.

[0044] 2. Both the base and the padlock have pull cords. The base is a fixed part with a larger main pull cord, while the padlock is a movable part with a smaller secondary pull cord. Both pull cords can accommodate the pull cord, allowing for a longer pull cord without increasing the size of the base. This expands the customer's range of motion and facilitates better trying on and testing of the product.

[0045] 3. During normal use, only the main cable puller of the base retracts or releases the cable, while the auxiliary cable puller of the padlock is locked. Pushing the limiter of the padlock can open the auxiliary cable puller to retract or release the cable. Releasing the limiter will relock the auxiliary cable puller, making it convenient for customers to adjust the cable length.

[0046] 4. Bring the magnetic unlocker close to the padlock to open the lock cylinder and pull out the plug.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
