The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0029] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.
[0030] The preferred implementation of the utility model is now further described in conjunction with the accompanying drawings. Figures 1 to 5As shown, the knob-type floating heat dissipation test seat includes an upper cover assembly 10 and a base 20. A placement groove 21 is provided in the base 20. The placement groove 21 is used to place the product to be tested. The upper cover assembly 10 includes an upper cover body 100 and a heat dissipation pressing block 200 stacked together. The heat dissipation pressing block 200 is used to press the product from the top when the product is placed in the placement groove 21, so as to ensure that the heat dissipation pressing block 200 can keep in contact with the product when the product is tested, so as to ensure that the product can maintain heat dissipation during the test. One end of the upper cover body 100 is movably connected to the base 20, and a floating plate 300 is provided between the upper cover body 100 and the heat dissipation pressing block 200. The floating plate 300 is connected to the heat dissipation pressing block 200, and a knob assembly 4 is provided on the upper cover body 100. 00, the knob assembly 400 passes through the upper cover 100 and is connected to the floating plate 300. When in use, the upper cover 100 of the upper cover assembly 10 is first opened relative to the base 20, and then the product to be tested is placed on the placement groove 21, and then the upper cover 100 is buckled, and the control knob assembly 400 drives the floating plate 300 to move downward, thereby driving the heat dissipation block 200 to move downward, so that the heat dissipation block 200 presses the top of the product to be tested, ensuring that the heat dissipation block 200 can keep in contact with the product during the test, thereby ensuring that the product can maintain heat dissipation during the test. After the test is completed, the control knob assembly 400 drives the floating plate 300 to move upward, thereby driving the heat dissipation block 200 to move upward, so that the heat dissipation block 200 is separated from the top of the product to be tested. From the above embodiment, it can be seen that the present application can use the knob assembly 400 and the floating plate 300 to ensure that the product can quickly press and contact the product during the test, ensuring that the product can maintain heat dissipation during the test.
[0031] On the basis of the above embodiments, Figure 2 As shown, the heat dissipation pressing block 200 includes a pressing plate 210, and heat sinks 220 are arranged on the left and right sides of the pressing plate 210. When the control knob assembly 400 drives the floating plate 300 to move downward, thereby driving the heat dissipation pressing block 200 to move downward, the pressing plate 210 can contact the top of the product, and then the heat generated by the test product is conducted to the heat sinks 220 on the left and right sides through the pressing plate 210 for heat dissipation. In this way, there is no need to stack the heat sink 220 and the pressing plate 210, thereby reducing the overall height of the utility model.
[0032] On the basis of the above embodiments, Figures 2 to 4As shown, the upper cover body 100 includes an upper cover member 110, and a first fixing portion 120 and a second fixing portion 130 are respectively extended downward at the front and rear ends of the upper cover member 110, and a first rotating shaft 121 is provided on the first fixing portion 120. The base 20 is connected to the first rotating shaft 121 to form a movable connection with the upper cover member 110. A first threaded hole 140 is provided on the upper cover body 100, and the knob assembly 400 is inserted into the first threaded hole 140 to form a threaded connection, that is, the knob assembly 400 can be raised and lowered by rotating in the first threaded hole 140. The floating plate 300 is arranged between the upper cover 110 and the pressure plate 210. Since the heat sink 220 is arranged on the left and right sides of the pressure plate 210, and the first fixing portion 120 and the second fixing portion 130 extend downward at the front and rear ends of the upper cover 110 respectively, when the upper cover 100 and the heat dissipation pressing block 200 are stacked together, the heat sink 220, the first fixing portion 120 and the second fixing portion 130 will be staggered with each other and will not be stacked together, thereby avoiding the increase of the overall height after multiple components are stacked.
[0033] On the basis of the above embodiments, Figure 2 , Figure 3 and Figure 5 As shown, a plurality of first stroke rods 150 are arranged in the upper cover 110, and the first stroke rods 150 are elastically connected to the upper cover 110. The first stroke rods 150 extend from the bottom of the upper cover 110 and are connected to the floating plate 300. In this way, when the knob assembly 400 controls the floating plate 300 to descend, the first stroke rods 150 provide resistance to the descent of the floating plate 300, thereby preventing the knob assembly 400 from descending too quickly, causing the heat dissipation pressing block 200 to descend too quickly and damage the product.
[0034] On the basis of the above embodiments, Figure 2 and Figure 5 As shown, a plurality of second stroke rods 310 are provided between the floating plate 300 and the pressure plate 210. The second stroke rods 310 enable the pressure plate 210 to move along the second stroke rods 310, so that there can be a space between the floating plate 300 and the pressure plate 210, and a spring 320 can be provided in the space. When the floating plate 300 drives the pressure plate 210 to descend so that the pressure plate 210 contacts the top of the product, the spring 320 between the floating plate 300 and the pressure plate 210 will be compressed, thereby further avoiding the situation where the knob assembly 400 descends too quickly, causing the heat dissipation pressing block 200 to descend too quickly and crush the product.
[0035] On the basis of the above embodiments, Figure 2 and Figure 4As shown, the knob assembly 400 includes a threaded column 410 and a rotating member 420. The threaded column 410 can be driven into the first threaded hole 140 by rotating the rotating member 420. A stopper 141 is provided in the first threaded hole 140, and a protrusion 421 is provided on the rotating member 420. When the rotating member 420 is rotated, the protrusion 421 will contact the stopper 141, thereby limiting the rotation range of the rotating member 420. This avoids the operator from rotating the rotating member 420 too much, thereby preventing the knob assembly 400 from descending too quickly, causing the heat dissipation block 200 to descend too quickly and crush the product.
[0036] On the basis of the above embodiments, Figure 1 As shown, a positioning plate 22 is provided in the base 20, and a through hole 23 for inserting a test probe is provided in the positioning plate 22. When the product is placed in the placement groove 21, it will be fixed by the positioning plate 22, so as to prevent the product from shaking left and right before and after the test.
[0037] On the basis of the above embodiments, Figure 1 As shown, a second rotating shaft 131 is provided on the second fixing portion 130, and a clasp 132 is installed on the second rotating shaft 131. The clasp 132 can rotate along the second rotating shaft 131, and a clamping portion 24 is provided on the base 20. When the upper cover 100 is fastened to the base 20 by using the first rotating shaft 121, the clasp 132 is rotated to buckle it out of the clamping portion 24, thereby ensuring that the front of the upper cover 100 and the base 20 is closed.
[0038] The above exemplary embodiments are detailed, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, so it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
