Description

Technical Field

[0001] This utility model relates to the field of durability testing, and in particular to the field of door lock durability testing technology, specifically a door lock life testing bench. Background Technology

[0002] With the rapid development of smart home appliances and electronic door lock technology, the reliability requirements for PTC door locks, roller electronic door locks and pulsator electronic door locks are increasing.

[0003] Traditional door lock life testing equipment is typically designed for a single door lock type, such as simulating the opening and closing actions of a single door lock using dedicated fixtures and drive modules. This has the following significant drawbacks: First, different door locks require independent testing equipment due to structural differences, resulting in high purchase costs and low testing efficiency for enterprises. Second, existing equipment cannot flexibly accommodate the installation interfaces and action parameters of multiple types of door locks, making it difficult to simulate complex working conditions. Third, parallel testing with multiple devices occupies a large amount of space, and the data acquisition system is scattered, making unified analysis difficult.

[0004] Although some improvement solutions attempt to adapt to multi-specification testing through modular structures, they are still limited by problems such as insufficient mechanical compatibility and low drive control precision, and cannot meet the home appliance industry's demand for efficient and intensive testing of multiple types of door locks.

[0039] This utility model proposes a door lock life test bench for use in door lock durability testing. This utility model does not limit the type of door lock, but the structure of the door lock life test bench is particularly suitable for durability testing of PTC door locks, roller electronic door locks, and pulsator electronic door locks.

[0040] In general, the door lock life testing bench proposed in this utility model mainly includes a base 1, a frame 2, a door hook mounting unit, a lock cylinder mounting unit, and a protective plate unit. See also... Figure 1 It shows the arrangement of base 1, frame 2, door hook mounting unit, lock cylinder mounting unit and guard plate unit.

[0041] To achieve the goal of adapting to different door locks for durability testing on the same device, and to address the shortcomings of traditional door lock life testing equipment designed for single door lock types (e.g., simulating the opening and closing actions of a single door lock using dedicated fixtures and drive modules), the following significant drawbacks exist: First, different door locks require independent testing equipment due to structural differences, resulting in high purchase costs and low testing efficiency for enterprises; second, existing equipment cannot flexibly accommodate the installation interfaces and action parameters of multiple types of door locks, making it difficult to simulate complex working conditions; third, parallel testing with multiple devices occupies a large space, and the data acquisition system is scattered, making unified analysis difficult; although some improvement solutions attempt to adapt to multi-specification testing through modular structures, they are still limited by insufficient mechanical compatibility and low drive control precision, failing to meet the needs of the home appliance industry for efficient and intensive testing of multiple types of door locks. Therefore, the technical solution provided in this embodiment utilizes a door hook mounting unit installed on the operating surface 3 of the frame 2 to achieve a structure that integrates two or even five or more different locks to be tested on the same base 1, which is convenient and quick, enabling durability testing of electronic locks on the same device with high efficiency and effectively reduced costs.

[0042] like Figure 1 As shown, the base 1 is a horizontal mounting platform used to support the overall structure. The frame 2 is fixedly mounted on the base 1. Its side near the operation side is divided into three continuous functional surfaces: two operation surfaces 3 and one control surface 4. The control surface 4 is located between the two operation surfaces 3. The three are arranged in an isosceles trapezoidal layout. Specifically, one control surface 4 is set vertically, and the two operation surfaces 3 are bent towards the side away from the operation direction and symmetrically inclined on both sides of the control surface 4, forming an ergonomic operating interface. In addition, a cabinet door 5 is installed on the back side of the frame 2, which forms a maintenance cavity to accommodate pneumatic pipelines and electrical control components. The cabinet door 5 is connected by hinges and is equipped with a safety interlock switch, which facilitates the installation and repair of parts by the operator from the rear of the frame 2.

[0043] The door hook mounting unit and the lock cylinder mounting unit need to be described in detail. They are arranged opposite each other and are used to install the electronic lock to be tested, so that multiple locks can be tested on the same device at the same time.

[0044] First, the door hook mounting unit includes an upper and lower drive cylinder 6, a guide rail 7, a connecting bracket 8, and a horizontal drive cylinder 9. The upper and lower drive cylinder 6 is vertically fixed to the upper part of the operating surface 3 by the bracket, and its piston rod extends downward. The guide rail 7 is vertically installed in the middle of the operating surface 3 by bolts and is collinear with the central axis of the upper and lower drive cylinder 6. The guide rail 7 is slidably engaged with the connecting bracket 8 by a linear slider, and the top of the connecting bracket 8 is rigidly connected to the piston rod of the upper and lower drive cylinder 6. The horizontal drive cylinder 9, which drives and installs the door hook horizontally, is arranged laterally, and its cylinder body is fixed to the connecting bracket 8 by the bracket, with its piston rod extending towards the lock cylinder mounting unit.

[0045] The corresponding lock cylinder installation unit is installed on the operating surface 3 via a modular bracket 10, and its position corresponds one-to-one with the horizontal drive cylinder 9; the bracket 10 can be replaced according to the lock cylinder model, including a U-shaped slot bracket for cylindrical locks or an L-shaped positioning bracket for top and bottom locks.

[0046] Preferably, 3-5 sets of horizontal drive cylinders 9 are arranged at equal intervals along the vertical direction on each operating surface 3. At the same time, multiple lock cylinder installation units are provided with corresponding horizontal drive cylinders 9, which facilitates the setting of multiple lock cylinder installation units to support parallel testing, fully covering the life verification requirements of different lock cylinder models or installation angles. Meanwhile, the equally spaced structure in the vertical direction provides an intuitive physical reference for debugging and calibration, improving the convenience of operation.

[0047] Based on this, the guard plate unit is detachably installed on the outside of the operating surface 3 and the control surface 4, protecting the door hook installation unit and the lock cylinder installation unit inside. The guard plate unit is equipped with an L-shaped connecting plate 11, connecting bolts 12 and guard plate 13. The horizontal side of the connecting plate 11 is fixed to the top of the frame 2 by screws, and the vertical side extends downward and covers the outer edge of the operating surface 3 and the control surface 4. During installation, the guard plate 13 is suspended on the connecting bolts 12 through the hanging holes opened at the top. The bolt ends are equipped with anti-loosening nuts, which facilitates the quick disassembly and installation of the guard plate, and can also effectively avoid the influence of impurities during the door lock life test process, while also playing a role in noise isolation.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
