The bottom of the snap-fit ​​plate and the top of the convex plate are respectively attached to the outer wall of the L-shaped snap-fit ​​plate, and the bottom of the snap-fit ​​plate and the top of the convex plate are respectively slidably arranged with respect to the outer wall of the L-shaped snap-fit ​​plate. The shape of the fixing block two is the same as that of the fixing block one, and the fixing block two is arranged opposite to the fixing block one.

[0009] As a preferred technical solution of this utility model: the shape of the first heat preservation box body matches the shape of the second heat preservation box body, and the inner wall of the first heat preservation box body and the outer wall of the second heat preservation box body are slidably fitted together.

[0010] As a preferred technical solution of this utility model: the first slide and the second slide have the same shape, and the first slide and the second slide are respectively connected through the first insulation box and the second insulation box. The outer wall of the first pin and the outer wall of the second pin are respectively attached to the inner wall of the first slide and the second slide, and the outer wall of the first pin and the outer wall of the second pin are respectively slidably connected to the inner wall of the first slide and the second slide.

[0011] As a preferred technical solution of this utility model: the trapezoidal block one, pin one, spring one, trapezoidal block two, pin two and spring two have the same shape, and the trapezoidal block one, pin one, spring one, trapezoidal block two, pin two and spring two are respectively arranged opposite to the sleeve as the center.

[0012] As a preferred technical solution of this utility model: the bottom of the sleeve is arc-shaped and is slidably fitted to the outer wall of trapezoidal block two and the outer wall of trapezoidal block one, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This low-temperature resistant power adapter, through the design of trapezoidal block one, trapezoidal block two, and sleeve, allows the rotating bolt rod to drive the sleeve to approach the top of trapezoidal block one and trapezoidal block two. When the arc-shaped sleeve at the bottom contacts the top of trapezoidal block one and trapezoidal block two, trapezoidal block one and trapezoidal block two will push towards both sides of the sleeve as the center. This causes trapezoidal block one and trapezoidal block two to drive pin two and pin one to slide along the direction of slide groove one and slide groove two, thereby achieving the fixation of the insulation box one and insulation box two after the pin two overlaps. At the same time, by performing the reverse operation, the fixation of the insulation box one and insulation box two after they overlap can be detached, thus realizing the quick disassembly and installation of the insulation box one and insulation box two of the power adapter.

[0015] 2. This low-temperature resistant power adapter, through the design of the snap-fit ​​plate and the convex plate, allows the two cylinders to be pressed, causing them to move downwards along the inner wall of the housing. This, in turn, moves the snap-fit ​​plates, causing the bottom outer walls of the two snap-fit ​​plates to slide against the outer wall of the L-shaped snap-fit ​​plate. During this sliding motion, spring four is compressed. Simultaneously, as the two snap-fit ​​plates slide and the L-shaped snap-fit ​​plate moves closer to the inner wall of the housing, it compresses spring three, thus... When the bottoms of the two snap-fit ​​plates move to the bottom of the L-shaped snap-fit ​​plate, the L-shaped snap-fit ​​plate will spring back under the compression of the third spring, thereby snapping the bottom of the L-shaped snap-fit ​​plate into contact with the bottoms of the two snap-fit ​​plates. At the same time, after the two snap-fit ​​plates are snapped into contact with the L-shaped snap-fit ​​plate, the fixing block two at the bottom of the snap-fit ​​plate will fit against the opposite fixing block one, thereby fixing the power adapter cable at a certain angle between the fixing block two and the fixing block one, so that the power adapter cable will not bend at a large angle when the power adapter is moved.

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-8 A low-temperature resistant power adapter includes an insulated box body 1, an insulated box body 2 on the top of the insulated box body 1, a circular groove 3 and a square groove 4 on the inner wall of the insulated box body 2, a sliding groove 5 and a sliding groove 7 on the inner wall of the square groove 4, a locking assembly 6 in the inner cavity of the square groove 4, a fixing block 8 fixedly mounted on the outer wall of the insulated box body 1, a box body 9 fixedly mounted on the outer wall of the insulated box body 2, and a fixing assembly 10 in the inner cavity of the box body 9.

[0027] The locking assembly 6 includes a bolt rod 601, the outer wall of which is threadedly connected to a sleeve 602, and the inner cavity of the square groove 4 is respectively provided with a trapezoidal block 603, a pin 604, a spring 605, a trapezoidal block 606, a pin 607, and a spring 608.

[0028] In the above structure, by setting the locking component 6 and the fixing component 10, when the insulation box 1 and the insulation box 2 are attached to each other, the locking component 6 will engage with the insulation box 2 through the square groove 4 opened in the inner cavity of the insulation box 1. At the same time, after the insulation box 1 and the insulation box 2 are engaged and installed, the fixing component 10 will fix the power adapter cable at a certain angle.

[0029] In a preferred embodiment: the fixing component 10 includes an L-shaped clamping plate 101, the outer wall of the L-shaped clamping plate 101 is provided with a spring three 102, the inner wall of the housing 9 is slidably connected with a cylinder one 103 and a cylinder two 107, the outer wall of the cylinder one 103 is fixedly fitted with a snap-fit ​​plate 104, the bottom of the snap-fit ​​plate 104 is provided with a spring four 105, the bottom of the cylinder one 103 is fixedly fitted with a fixing block two 106, the outer wall of the cylinder two 107 is fixedly fitted with a convex plate 108, the bottom of the convex plate 108 is provided with a spring five 109;

[0030] In a preferred embodiment: there are two cylinders 103, two snap-fit ​​plates 104, and two springs 105, and each cylinder 103, snap-fit ​​plate 104, and spring 105 is arranged symmetrically with cylinder 2 107, convex plate 108, and spring 5 109 as the center. The bottom of snap-fit ​​plate 104 and the top of convex plate 108 are respectively attached to the outer wall of L-shaped snap-fit ​​plate 101, and the bottom of snap-fit ​​plate 104 and the top of convex plate 108 are respectively slidably disposed with respect to the outer wall of L-shaped snap-fit ​​plate 101. The shape of fixing block 2 106 is the same as that of fixing block 1 8, and fixing block 2 106 is disposed opposite to fixing block 1 8.

[0031] In the above structure, by setting up the L-shaped locking plate 101, the convex plate 108, and the locking plate 104, pressing the two cylinders 103 causes them to move downwards along the inner wall of the housing 9. This causes the locking plates 104 to move, resulting in the bottom outer walls of the two locking plates 104 contacting and sliding with the outer wall of the L-shaped locking plate 101. During this sliding motion, the spring 105 compresses, and simultaneously, as the L-shaped locking plate 101 moves closer to the inner wall of the housing 9, it compresses the spring 102. When the bottoms of the two locking plates 104 reach the bottom of the L-shaped locking plate 101, the L-shaped locking plate 101 rebounds under the compression of the spring 102, thus achieving locking between the bottom of the L-shaped locking plate 101 and the bottoms of the two locking plates 104. After the latching plate 104 is latched by the L-shaped latching plate 101, the fixing block 2 106 at the bottom of the latching plate 104 will fit against the opposite fixing block 1 8, thereby fixing the power adapter cable at a certain angle by the fixing block 2 106 and the fixing block 1 8. At the same time, by pressing the cylinder 2 107, the cylinder 2 107 moves downward along the inner wall of the housing 9, which will drive the convex plate 108 to move downward. When the top of the convex plate 108 slides against the outer wall of the L-shaped latching plate 101, the L-shaped latching plate 101 will move closer to the inner wall of the housing 9 and drive the spring 3 102 to compress. When the bottom of the L-shaped latching plate 101 moves closer to the inner wall of the housing 9, it will disengage from the bottom of the two latching plates 104. Thus, after the two latching plates 104 are disengaged from the L-shaped latching plate 101, they will also be driven by the compression and rebound of the spring 4 105 to reset the fixing block 2 106.

[0032] In a preferred embodiment: the shape of the heat preservation box 1 matches the shape of the heat preservation box 2, and the inner wall of the heat preservation box 1 and the outer wall of the heat preservation box 2 are slidably fitted together.

[0033] In the above structure, by setting up the insulation box 1 and the insulation box 2, and by sliding the outer wall of the insulation box 2 along the inner wall of the insulation box 1, the insulation box 1 and the insulation box 2 will overlap and become a heat insulation cover to protect the power adapter.

[0034] In a preferred embodiment: the first slide 5 and the second slide 7 have the same shape, and the first slide 5 and the second slide 7 are respectively connected through the first insulation box 1 and the second insulation box 2. The outer wall of the first pin 604 and the outer wall of the second pin 607 are respectively attached to the inner wall of the first slide 5 and the second slide 7, and the outer wall of the first pin 604 and the outer wall of the second pin 607 are respectively slidably connected to the inner wall of the first slide 5 and the second slide 7.

[0035] In the above structure, by setting the first pin 604, the second pin 607, and the first slide 5 and the second slide 7, the first pin 604 and the second pin 607 will move along the direction of the first slide 5 and the second slide 7 under the push of the first trapezoidal block 603 and the second trapezoidal block 606. In this way, the first pin 604 and the second pin 607 will fix the first insulation box 1 and the second insulation box 2 through the slide 5 and the second slide 7 that are formed through the first insulation box 1 and the second insulation box 2.

[0036] In a preferred embodiment: trapezoidal block 603, pin 604, spring 605, trapezoidal block 606, pin 607 and spring 608 have the same shape, and trapezoidal block 603, pin 604, spring 605, trapezoidal block 606, pin 607 and spring 608 are respectively arranged opposite to the sleeve 602 with the sleeve as the center;

[0037] In the above structure, by setting trapezoidal block 603, pin 604, spring 605, trapezoidal block 606, pin 607, and spring 608, trapezoidal block 603 and trapezoidal block 606, centered on sleeve 602, will push in opposite directions. This will cause pin 604, spring 605, pin 607, and spring 608 to move and compress under the opposite push of trapezoidal block 603 and trapezoidal block 606.

[0038] In a preferred embodiment: the bottom of the sleeve 602 is arc-shaped and is slidably fitted to the outer wall of trapezoidal block 2 606 and the outer wall of trapezoidal block 1 603 respectively;

[0039] In the above structure, by setting the sleeve 602, when the bolt rod 601 rotates clockwise, the sleeve 602 will move downward, so that when the bottom arc-shaped sleeve 602 contacts the top of the trapezoidal block 603 and the spring 608, the trapezoidal block 603 and the spring 608 will be pushed to both sides.

[0040] Working principle: When in use, the power adapter is placed on top of the insulation box 1. Then, the outer wall of the insulation box 2 slides along the inner wall of the insulation box 1. When the insulation box 1 and the insulation box 2 overlap, rotating the bolt rod 601 clockwise causes the sleeve 602 to move closer to the top of the trapezoidal block 603 and the trapezoidal block 606. When the arc-shaped sleeve 602 contacts the top of the trapezoidal block 603 and the trapezoidal block 606, the trapezoidal block 603 and the trapezoidal block 606... The sleeve 602 will be pushed to both sides, causing trapezoidal blocks 603 and 606 to slide along grooves 5 and 7, respectively. Simultaneously, trapezoidal blocks 603 and 606 will compress springs 605 and 608, thus fixing the insulation boxes 1 and 2 after they overlap. The reverse operation can disengage the insulation boxes 1 and 2 after they overlap. After the power adapter is fixed in the insulation box 2, pressing the two cylinders 103 causes them to move downwards along the inner wall of the box 9. This causes the two cylinders 103 to move the latching plates 104, resulting in the bottom outer walls of the two latching plates 104 contacting and sliding against the outer wall of the L-shaped latching plate 101. As the two latching plates 104 slide, the spring 4 105 is compressed. Simultaneously, as the two latching plates 104 slide and the L-shaped latching plate 101 moves closer to the inner wall of the box 9, it compresses the spring 3 102, causing the two latching plates to... When the bottom of the connector plate 104 moves to the bottom of the L-shaped latch plate 101, the L-shaped latch plate 101 will spring back under the compression of the spring 102, thereby enabling the bottom of the L-shaped latch plate 101 to engage with the bottom of the two latch plates 104. At the same time, after the two latch plates 104 are engaged by the L-shaped latch plate 101, the fixing block 106 at the bottom of the latch plate 104 will fit against the opposite fixing block 8, thereby fixing the power adapter cable at a certain angle by the fixing block 106 and the fixing block 8, so that the power adapter cable will not bend at a large angle when the power adapter is moved.

[0041] 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 the present invention, the scope of which is defined by the appended claims and their equivalents.
