Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of product thrust testing, and particularly to a thrust test device for an electric device. Background Art
[0002] The thrust test is to test that the test sample (including chain or push rod) of the electric device is reliably fixed and installed in a specified installation manner, and then the specified thrust is used to push the claimed stroke with load. After reaching the specified stroke, it retracts back.
[0003] The national standard "Fire Alarm Linkage Controller" stipulates the thrust test. The thrust test requires the product to be reliably installed in its normal installation manner. The shapes of the test samples include circular, square, etc. In the test, it is required that after the test sample is installed in its installation manner, the force-receiving end of the chain or push rod is reliably connected to the thrust application terminal, and the force-receiving end extends out to push the rated load to reach the required stroke.
[0004] The existing thrust test devices for electric devices can already test the thrust of chain-type or push-rod-type electric devices. The device usually includes key components such as a controller, a thrust guide rail, a test load, a thrust application terminal, etc. Through the coordinated work of these components, the device can respectively test the thrust of chain-type samples and push-rod-type electric device samples, realizing the quick and reliable fixation of the tested samples, and having good repeatability and consistency. The device is easy to operate and can improve the test efficiency to a certain extent. In addition, the existing thrust test devices also have the following disadvantages in use:
[0005] (1) When the existing thrust test device conducts a thrust test, it usually needs to push and stretch and contract with load within a certain space. However, in actual operation, due to the limitation of the device structure design, the space utilization rate is often not high. Especially when conducting a long-stroke test, it requires a large space, which not only increases the cost but also limits the flexibility of the test environment;
[0006] (2) The test samples (such as chains or push rods) of the existing thrust test devices may accidentally break due to excessive thrust, thus causing safety risks.
[0007] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes the prior art already known to those of ordinary skill in the art. Summary of the Utility Model
[0008] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a thrust test device for an electric device.
[0009] To solve the above problems, the technical solution of the present utility model includes a controller, a load, a load traction rope, a support frame, a protective cover, a thrust application terminal, a fixed clamp, and a thrust guide rail. One side of the top of the support frame is provided with a fixed clamp, and the other side is provided with a load traction rope. Inside the support frame, near the side of the fixed clamp, there is a controller. On the opposite side of the fixed clamp and the load traction rope, there is a thrust guide rail. Near the side of the fixed clamp on the thrust guide rail, there is a thrust application terminal. At the rear side of the top of the support frame, there is a foldable protective cover. The bottom end of the load traction rope is inserted with a number of equally spaced loads.
[0010] Furthermore, the thrust application terminal is electrically connected to the controller, and the protective cover is fixed to the support frame through a limiting structure.
[0011] The advantages of the present utility model compared with the existing technology are as follows:
[0012] 1. The present utility model provides a thrust test device for an electric device. By using the combination of a load traction rope and a fixed pulley, the connection and adjustment of the test load are made more flexible, capable of adapting to changes in different load levels and test requirements, reducing the space for the load to push and stretch, and increasing the flexibility of the test environment.
[0013] 2. The present utility model provides a thrust test device for an electric device. By adding a protective cover, it effectively prevents possible accidents during the test, protecting the safety of the surrounding environment and personnel. Description of the Drawings

[0018] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.
[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] As Figures 1 to 3 shown, this embodiment provides a thrust test device for an electric device, including a controller 1, a load 2, a load traction rope 3, a support frame 4, a protective cover 5, a thrust application terminal 6, a fixed fixture 7, and a thrust guide rail 8. On one side of the top of the support frame 4, there is a fixed fixture 7 (which belongs to the prior art and will not be elaborated here), and on the other side, there is a load traction rope 3. Inside the support frame 4, near one side of the fixed fixture 7, there is a controller 1. On the opposite side of the fixed fixture 7 and the load traction rope 3, there is a thrust guide rail 8. Near the fixed fixture 7 on the thrust guide rail 8, there is a thrust application terminal 6. At the rear side of the top of the support frame 4, there is a foldable protective cover 5. At the bottom end of the load traction rope 3, several equally spaced loads 2 are inserted. The thrust application terminal 6 is electrically connected to the controller 1, and the protective cover 5 is fixed to the support frame 4 through a limiting structure.
[0021] During specific use, the controller 1 is used to provide power to the test sample, control the test system to complete the push - stretch operation, and can also control the completion of the automatic cycle operation. The load 2 is used to provide the rated load required for the test, including different load levels such as 100N and 50N, providing combinations under various load conditions to meet the load configuration required for the test. The load traction rope 3 is used to connect the load 2. During the extension process of the sample, the load traction rope 3 travels along the thrust guide rail 8, turns through a fixed pulley, and drives the test load 2 to rise; during the contraction process of the sample, the load traction rope 3 travels along the thrust guide rail 8, driving the test load 2 to fall. The protective cover 5 is used to protect against accidental breakage of test samples such as chains during the test, preventing damage to surrounding personnel and objects. The actuating structure of the test sample is connected to the thrust application terminal 6, and the actuating mechanism drives the thrust application terminal 6 to complete the extension and contraction processes, and the extension and contraction processes are carried out along the straight - line trajectory of the thrust guide rail 8.
