Description

Technical Field

[0001] This utility model belongs to the technical field of temperature shock testing, and in particular relates to a two-chamber temperature shock test chamber. Background Technology

[0002] Temperature shock testing refers to a test method used to assess a product's adaptability to rapid changes in ambient temperature. It simulates rapid alternation between high and low temperatures to evaluate a product's performance and stability under extreme temperature conditions. High and low temperature shock test chambers are used in the temperature shock testing process. These chambers are classified into three-chamber and two-chamber types based on testing requirements and standards. The difference lies in the testing method and internal structure. The three-chamber type consists of a cold storage chamber, a heat storage chamber, and a test chamber; the product is placed in the test chamber during testing. The two-chamber type consists of a high-temperature chamber and a low-temperature chamber, with the switching between high and low temperatures achieved by a motor-driven basket. The product is placed in the basket and moves with it. However, it still has the following shortcomings in practical use:

[0003] 1. In the use of the two-chamber temperature shock test chamber, the test object is placed inside the basket, the motor is powered on, and the height of the basket is adjusted so that the basket moves from the high chamber to the low chamber and from the low chamber to the high chamber, thereby realizing the temperature shock test on the test object inside the basket. After the temperature shock test is completed, the chamber door is opened and the test object is taken out one by one from the high chamber or the low chamber. However, the temperature inside the high chamber is higher and the temperature inside the low chamber is lower. If the operator's hands enter the high chamber or the low chamber repeatedly, it will increase the adverse effects on the hands and may even cause burns or frostbite, reducing safety.

[0004] 2. Secondly, when placing the test objects inside the basket, the position of the test objects is not limited as the basket moves up and down. This can cause the test objects to move up and down with the basket, and may even cause collisions and damage to the test objects, thus reducing the quality of the test objects after completing the temperature shock test.

[0005] To address these issues, we provide a two-chamber temperature shock test chamber. Utility Model Content

Detailed Implementation

[0028] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1, please refer to Figure 1 and Figure 2 This utility model is a two-chamber temperature shock test chamber, including a chamber body 1, a low temperature chamber 101, a high temperature chamber 101a and a chamber door 103. The low temperature chamber 101 and the high temperature chamber 101a provide different temperatures to the test object, so as to realize the high and low temperature shock test on the test object.

[0030] Specifically, the inner wall of the box 1 has a fixed sleeve plate 102 in the middle, which divides the internal space of the box 1 into a low temperature chamber 101 and a high temperature chamber 101a. The opening side of the box 1 has a hinged door 103, with an observation window embedded in the center of the door 103. The side wall of the door 103 has a door handle installed. The corners of the lower surface of the box 1 have casters installed. The lower surface of the box 1 has a connecting cylinder installed.

[0031] Furthermore, the low-temperature chamber 101 is located below the cover plate 102, and the high-temperature chamber 101a is located above the cover plate 102, with the two chamber doors 103 arranged symmetrically.

[0032] The operation process of this embodiment is as follows: push the box 1, move the casters, move the box 1 to the test position, turn the screw counterclockwise, and the anti-slip seat downward to contact the ground.

[0033] Example 2, please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5Based on the specific embodiment one, a storage component 2 is provided. The storage component 2 includes a storage box 201, a basket 202, a motor 203, a take-up and release shaft 203a, a steel rope 203b, a baffle 205, and a return spring 205b. The storage box 201 is used to store the test object. When the motor 203 is energized, it drives the basket 202 to move up and down to realize the high and low temperature impact test on the test object. The baffle 205 is used to lock the position of the storage box 201 inside the basket 202. Pressing down on the baffle 205 releases the lock on the storage box 201, making it convenient to completely remove the test object that has completed the high and low temperature impact test from inside the basket 202 at one time. This avoids the need for staff to repeatedly enter the high temperature chamber 101a or the low temperature chamber 101 to retrieve the test object, reduces the adverse effects of high and low temperatures on the hands, and increases safety.

[0034] Specifically, the basket 202 is fitted inside the sleeve 102. A protective shell 204 is installed on the upper surface of the housing 1. Inside the protective shell 204 is a laterally rotatable retractable shaft 203a. A coiled steel rope 203b is located around the periphery of the protective shell 204. The free end of the steel rope 203b passes through the upper surface of the housing 1 and is attached to the upper surface of the basket 202. A motor 203 is installed on the side wall of the protective shell 204. The output end of the motor 203 is connected to the end of the retractable shaft 203a. A storage box 201 is placed inside the basket 202. An opening is located at the bottom of the basket 202. The storage slot 202a is close to the opening side of the basket 202. The storage slot 202a has holes 202b at both ends. A baffle 205 is provided above the storage slot 202a. The two ends of the baffle 205 are inserted into the holes 202b. The lower surface of the baffle 205 has a return spring 205b connected to both ends. The lower end of the return spring 205b is connected to the inner bottom of the holes 202b. The upper surface of the baffle 205 has through holes 205a at both ends. A guide rod 205c is vertically fixed at the center of the inner bottom of the holes 202b.
