[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 An electrical testing environmental test specimen stand includes a test chamber 1. An adjustable mounting assembly 2 is installed inside the test chamber 1, and an opening / closing assembly 3 is provided on one side of the test chamber 1. The adjustable mounting assembly 2 includes a slide rail 201, a slot 202 is provided on the inner side of the slide rail 201, a specimen stand 203 is mounted on one side of the slide rail 201, and placement slots 204 are provided on both sides of the specimen stand 203. A locking block 205 is placed inside the placement slot 204, and a sliding rod 206 is installed at the upper end of the locking block 205. A first sliding groove 207 is provided on the specimen stand 203 at a corresponding position where the sliding rod 206 moves. A bolt 208 is provided on one side of the sample stand 207. A fixing block 209 is installed on the upper end of the sample stand 203. The fixing block 209 has a screw hole 210 at the corresponding position of the bolt 208. The opening and closing assembly 3 includes an installation chamber 301. A motor 302 is installed on one side of the installation chamber 301. A positive and negative lead screw 303 is installed at the output end of the motor 302. A moving block 304 is sleeved on the outside of the positive and negative lead screw 303. A slider 305 is provided at the lower end of the moving block 304. A second slide groove 306 is provided at the corresponding position of the slider 305 in the installation chamber 301. An opening and closing door plate 307 is provided at the lower end of the second slide groove 306.

[0026] Through the above technical solution, the adjustable installation component 2 facilitates the adjustment of the position of the test sample platform 203, flexibly matching electrical appliances of different sizes, thus improving practicality to a certain extent. By moving the test sample platform 203 to a suitable position, the sliding rod 206 is moved, which in turn moves the bolt 208. Simultaneously, the movement of the sliding rod 206 moves the locking block 205, causing one end of the locking block 205 to engage in the slot 202. By screwing one end of the bolt 208 into the screw hole 210 to fix the position of the sliding rod 206, the locking block 205 is stably engaged in the slot 202, thus enabling the test sample to be tested. The position of the stand 203 is limited and adjusted to a suitable position for easy use. The opening and closing of the test chamber 1 is automatically controlled by the set opening and closing components 3, which facilitates operation to a certain extent. By starting the motor 302, the motor 302 drives the positive and negative lead screws 303 to rotate. The rotation of the positive and negative lead screws 303 drives the symmetrically set moving blocks 304 to move relative to each other. The relative movement of the symmetrically set moving blocks 304 drives the relative movement of the symmetrically set sliders 305. The relative movement of the symmetrically set sliders 305 drives the relative movement of the symmetrically set opening and closing door plates 307. By controlling the symmetrically set opening and closing door plates 307 to move away from each other, it is easy to open the test chamber 1 for subsequent operations.

[0027] Specifically, there are multiple sets of slide rails 201, which are symmetrically arranged inside the test chamber 1, and the sample platform 203 is slidably connected to the slide rails 201.

[0028] Through the above technical solution, multiple sets of slide rails 201 that are slidably connected to the test specimen platform 203 ensure the stability of the movement of the test specimen platform 203. The slide rails 201 play a certain role in bearing and guiding. The multiple sets of slide rails 201 are symmetrically distributed in the test chamber 1 to ensure balanced force, so that the test specimen platform 203 remains stable when bearing heavy objects, and provides a reliable guiding role for subsequent operations.

[0029] Specifically, there are multiple sets of card slots 202, which are equidistantly arranged on the inner side of the slide rail 201. There are also multiple sets of placement slots 204, which are symmetrically arranged on both sides of the sample stand 203.

[0030] Through the above technical solution, multiple sets of equally spaced slots 202 can be used in conjunction with the card blocks 205 to facilitate the adjustment of the position of the sample platform 203, and multiple sets of placement slots 204 can be used to place multiple sets of card blocks 205 to limit the position of the sample platform 203.

[0031] Specifically, the card block 205 is slidably set in the placement slot 204, and one end of the card block 205 is engaged with the card slot 202.

[0032] Through the above technical solution, the locking block 205 is precisely adapted to the placement groove 204, allowing the locking block 205 to slide freely within the placement groove 204. When the sample platform 203 is installed or its position is fixed, as the sample platform 203 moves along the slide rail 201 to the predetermined position, the locking block 205 is driven by external force and slides smoothly along the placement groove 204. One end of the locking block engages with the locking groove 202, limiting the position of the sample platform 203.

[0033] Specifically, the slide bar 206 passes through the sample stand 203 and extends to its upper end. The slide bar 206 is slidably set in the first slide groove 207. The bolt 208 passes through the slide bar 206 and extends to its outer side. One end of the bolt 208 matches the screw hole 210.

[0034] Through the above technical solution, the movable slide bar 206 is used to facilitate the movement of the locking block 205. One end of the locking block 205 is locked in the locking groove 202. By screwing one end of the bolt 208 into the screw hole 210, the position of the slide bar 206 is fixed, thereby performing a stable limiting operation on the position of the sample platform 203.

[0035] Specifically, the installation chamber 301 is detachably installed on one side of the upper end of the test chamber 1, the output end of the motor 302 is detachably connected to the positive and negative lead screw 303, and there are two sets of moving blocks 304. The two sets of moving blocks 304 are symmetrically arranged on the outside of the positive and negative lead screw 303, and the moving blocks 304 are matched with the positive and negative lead screw 303.

[0036] Through the above technical solution, the installation compartment 301 facilitates the installation of parts such as the motor 302 and the positive and negative lead screws 303, providing a certain support for their normal operation. The motor 302 is connected to an external power supply and controller to ensure the independent operation of each device. The motor 302 drives the positive and negative lead screws 303 to rotate, and the rotation of the positive and negative lead screws 303 drives the symmetrically arranged moving blocks 304 to move relative to each other.

[0037] Specifically, the slider 305 is slidably set in the second slide groove 306, and there are two sets of opening and closing door plates 307, which are symmetrically set on one side of the test chamber 1.

[0038] Through the above technical solution, the second slide groove 306 is used to ensure the stability of the movement of the slider 305. The relative movement of the symmetrically arranged sliders 305 drives the relative movement of the symmetrically arranged opening and closing door plates 307, thereby controlling the symmetrically arranged opening and closing door plates 307 to move closer or further apart, thus achieving the function of controlling the opening and closing of the test chamber 1.

[0039] In use, when the position of the sample platform 203 needs to be flexibly adjusted, move the sample platform 203 to the appropriate position, move the slide rod 206, and the movement of the slide rod 206 will cause the bolt 208 to move. At the same time, the movement of the slide rod 206 will cause the locking block 205 to move. One end of the locking block 205 is locked in the locking groove 202. By screwing one end of the bolt 208 into the screw hole 210, the position of the slide rod 206 is fixed, thereby making the locking block 205 stably locked in the locking groove 202, limiting the position of the sample platform 203. The frame 203 is adjusted to a suitable position for easy use. When the opening and closing of the test chamber 1 needs to be automatically controlled, the motor 302 is started. The motor 302 drives the positive and negative lead screws 303 to rotate. The rotation of the positive and negative lead screws 303 drives the symmetrically arranged moving blocks 304 to move relative to each other. The relative movement of the symmetrically arranged moving blocks 304 drives the symmetrically arranged sliders 305 to move relative to each other. The relative movement of the symmetrically arranged sliders 305 drives the symmetrically arranged opening and closing door plates 307 to move relative to each other. The symmetrically arranged opening and closing door plates 307 are controlled to move away from each other, so that the test chamber 1 can be opened for subsequent operations.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of this application. The scope of this application is defined by the appended claims and their equivalents.
