Description

Technical Field

[0001] This utility model belongs to the field of lock technology, and more specifically, it relates to an adjustable lock cylinder and lock gourd structure. Background Technology

[0002] In the field of lock manufacturing and installation, it is often necessary to use lock cylinders and lock gourds of appropriate specifications to adapt to the installation of door locks with different door thicknesses. However, traditional fixed-length lock cylinders and lock gourds do not have the function of adjustment according to door thickness. As a result, during the door lock installation process, due to the mismatch between the door thickness and the length of the lock cylinder and lock gourd, it is necessary to frequently change lock cylinders and lock gourds of different specifications. Under the dual effects of time and labor costs, this can easily lead to low installation efficiency and increased installation costs. This not only affects the progress of door lock installation business and leads to a decrease in customer satisfaction, but also increases the operating costs of manufacturers and distributors due to the need to keep multiple specifications in stock, thereby squeezing profit margins. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an adjustable lock cylinder and lock gourd structure to address the technical problem in the prior art where the length of the lock cylinder and lock gourd is fixed and cannot be adapted to different door thicknesses.

[0004] The purpose and function of this utility model's adjustable lock cylinder and gourd structure are achieved by the following specific technical means:

[0005] An adjustable lock cylinder hoist structure includes a support rod, two sets of connectors, and splicing components. The two sets of connectors are respectively sleeved on the outer front lock and the outer rear lock. The two ends of the support rod are respectively inserted into the two sets of connectors and fixed by screws. The splicing components are sleeved on the support rod.

[0006] A toggle element and a transmission element are provided between the two sets of joints, and the transmission element is sleeved inside the splicing component;

[0007] When it is necessary to extend the lock cylinder, the actuating element is sleeved on the splicing element and its rotation is limited by the splicing element;

[0008] When it is not necessary to extend the lock cylinder, the actuating element is sleeved on the connector and its rotation is limited by the connector; or the rotation of the actuating element is limited by both the splicing element and the connector.

[0009] The transmission component is driven by an external front lock and an external rear lock, and the actuating component is driven by the transmission component or directly driven by the external front lock and the external rear lock.

[0010] According to a preferred embodiment, the number of splicing components is one or more sets, and adjacent splicing components are disassembled and connected.

[0011] According to a preferred embodiment, the splicing component is provided with a limiting protrusion for limiting the rotation angle of the actuating component. When the actuating component is sleeved on the splicing component, the limiting protrusion cooperates with the limiting groove on the inner wall of the actuating component.

[0012] According to a preferred embodiment, the connector is provided with a limiting rib for limiting the rotation angle of the actuating member. When the actuating member is sleeved on the connector, the limiting rib cooperates with the limiting notch on the inner wall of the actuating member.

[0013] According to a preferred embodiment, the support rod includes multiple sets of symmetrical rods and eccentric rods.

[0014] According to a preferred embodiment, the inner wall of the connector is provided with an annular groove, and a retaining spring is engaged in the annular groove. The connector is connected to an external front lock and an external rear lock through the retaining spring.

[0015] According to a preferred embodiment, the screw passes through the joint radially and is threaded to the support rod, thereby fixing the joint to the support rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This utility model, by incorporating adjustable splicing components, allows the device to adapt to different door thicknesses, enhancing its versatility. The length of the entire lock cylinder and lock gourd can be adjusted by increasing or decreasing the number of splicing components, freeing the device from fixed length limitations. For example, with thicker doors, the number of splicing components can be increased to lengthen the lock cylinder, thus adapting to the door thickness; with thinner doors, the number of splicing components can be reduced. This improves the device's adaptability to different door thicknesses, reduces the cost of preparing multiple fixed-length lock cylinders and lock gourds due to varying door thicknesses, reduces inventory pressure for both manufacturers and retailers, and makes it easier for buyers to find products suitable for their door thicknesses.

[0018] 2. When using this device, the rotation angle of the actuating component can be limited by the cooperation of the limiting protrusion and limiting groove, and the limiting rib and limiting notch, thus improving the stability of the device during use. When the actuating component is fitted onto the splicing piece, the limiting protrusion on the splicing piece cooperates with the limiting groove on the inner wall of the actuating component; when the actuating component is fitted onto the connector, the limiting rib on the connector cooperates with the limiting notch on the inner wall of the actuating component. In this way, the rotation of the actuating component can be controlled under any circumstances. Then, by using screws to fix the connector and the support rod and using snap rings to connect the external front and rear locks, the connection between the various components of the device is reliable and not easy to loosen, ensuring the reliability and durability of the lock cylinder and lock gourd liner during long-term use, improving the overall quality and service life of the device, thereby enhancing the user experience and strengthening the product's competitiveness in the market.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0025] Example:

[0026] like Figures 1 to 3 As shown, this utility model provides an adjustable lock cylinder and gourd structure. Through the coordinated arrangement of two sets of connectors 11, support rods 15, and splicing parts 12, an adjustable length basic frame is formed. The two sets of connectors 11 are respectively fitted onto the external front lock and external rear lock, and the two ends of the support rods 15 pass through them and are fixed by screws 16. This ensures the stability of the overall structure and provides rigid support for length adjustment, enabling the device to adapt to different door thicknesses and improving its adaptability.

[0027] The device can extend or shorten the length of the lock cylinder by adding or removing the splicing parts 12: when extension is required, the splicing parts 12 are fitted onto the support rod 15, and the transmission parts 13 are simultaneously fitted into the splicing parts 12. At this time, the actuating parts 14 are fitted onto the splicing parts 12. The rotation angle of the actuating parts 14 is limited by the cooperation between the limiting protrusion on the splicing parts 12 and the limiting groove on the inner wall of the actuating parts 14. When extension is not required, the actuating parts 14 are fitted onto the joint 11. The limiting rib on the joint 11 cooperates with the limiting notch on the inner wall of the actuating parts 14 to achieve limitation, or the limitation is strengthened by the jointing parts 12 and the joint 11. This allows the device to maintain transmission stability under different length conditions, improves the operational reliability of the device, and enhances the adaptability of the device in complex assembly environments.

[0028] By using one or more sets of splicing parts 12 that are detachably connected to each other, the length can be adjusted according to actual needs. There is no need to keep multiple fixed specifications of lock cylinders in stock, which can significantly reduce inventory costs and improve the economic efficiency of the device.

[0029] The transmission component 13 is driven by an external front lock and an external rear lock, while the actuating component 14 can be driven by the transmission component 13 or directly by the external front lock and rear lock. This dual-drive path configuration can ensure the continuity of power transmission under different length adjustment states, enabling the device to avoid the limitations of a single drive mode and improve the transmission efficiency of the device.

[0030] The support rod 15 includes multiple sets of symmetrical rods and eccentric rods. By selecting different types of support rods 15 to match the splice 12 and the joint 11, it is possible to further adapt to the installation requirements of different door thicknesses, so that the device can optimize space occupation while ensuring structural strength and improve the structural rationality of the device.

[0031] An annular groove is formed on the inner wall of the connector 11, and the retaining spring 17 is engaged in the annular groove. The inner diameter of the retaining spring 17 is smaller than the outer diameter of the front lock and the rear lock. The retaining spring 17 prevents the front lock and the rear lock from falling out of the connector 11, so that the device can maintain connection stability during long-term use and improve the safety performance of the device.

[0032] The screw 16 passes radially through the connector 11 and is threadedly connected to the support rod 15. The connector 11 is firmly locked onto the support rod 15 by radial fixing, which facilitates installation and disassembly and resists loosening due to vibration during use. This allows the device to maintain structural stability during frequent operation and improves the service life of the device.

[0033] The specific usage and function of this embodiment are as follows:

[0034] First, select a suitable support rod 15 based on the door thickness, choosing from multiple sets of symmetrical and eccentric rods. If the door thickness is large, the lock cylinder needs to be extended, so select a support rod 15 of corresponding length and prepare one or more sets of splicing parts 12. If the door thickness is small, directly select a short support rod 15 and do not prepare splicing parts 12. During operation, place the two sets of connectors 11 on the external front lock and rear lock respectively, insert both ends of the support rod 15 into the connectors 11, and use screws 16 to pass through the connectors 11 radially and connect them to the support rod 15 with threads to fix the position of the connectors 11. This step ensures the stability of the overall structure through rigid connection, enabling the device to withstand vibrations during long-term use. When extension is required, place the splicing parts 12 sequentially on the support rod 15, with adjacent splicing parts 12 connected by a detachable structure, and simultaneously insert the transmission component 13 into the splicing parts 12. If extension is not required, do not install the splicing parts 12 and transmission component 13. Adjust the length by adding or removing splicing parts 12 to avoid stocking multiple specifications and reduce inventory costs. Next, a retaining spring 17 is inserted into the annular groove on the inner wall of the connector 11. Its inner diameter is smaller than the outer diameters of the front and rear locks to prevent detachment, ensuring stable component connection and improving safety. Finally, in the extended state, the actuating component 14 is fitted onto the splicing component 12, with the limiting protrusion and limiting groove restricting the rotation angle; in the non-extended state, it is fitted onto the connector 11, limited by the limiting rib and limiting notch. The dual drive path, with the transmission component 13 or the front and rear locks directly driving, ensures continuous power transmission, enabling stable operation of the device at different lengths and improving adaptability and reliability.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
