Description

Technical Field

[0001] This utility model relates to the field of container technology, and in particular to an explosion-proof and stable base for a thermos bottle. Background Technology

[0002] Thermos flasks, widely used in daily life, are characterized by their excellent heat retention performance. These containers typically consist of a double-walled structure with a vacuum insulation layer between the two walls. This design effectively slows down heat loss through conduction, convection, and radiation, thus achieving long-term heat or cold retention.

[0003] In the existing technology, during the use of thermos flasks, users often do not pay attention to handling them gently, causing the base of the thermos flask to collide with the ground or table. This can cause the inner liner of the thermos flask to burst due to the strong force, causing the boiling water inside to spill out and potentially causing burns to the user. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where, during use, users often fail to handle thermos flasks carefully, causing the base of the thermos flask to collide with the ground or table, resulting in the inner liner of the thermos flask bursting due to the strong force, causing boiling water to spill out and potentially scalding the user.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a thermos bottle explosion-proof and stable base, comprising: a thermos bottle body and a base, wherein the base is disposed below the thermos bottle body, and further comprising:

[0006] A connecting ring is fixedly connected to the top of the bottle base. The connecting ring is threaded to the body of the thermos. The inner wall of the connecting ring has multiple square grooves arranged in a circular array. A slider is slidably connected to the inner wall of each square groove. A support seat is fixedly connected to one side of each slider. The support seat is slidably connected to the connecting ring. A buffer spring is fixedly connected to the opposite side of each slider. One end of each buffer spring is fixedly connected to the opposite side of the inner wall of the square groove. Multiple dampers are fixedly connected to the top of the bottle base in a circular array. All of the dampers are fixedly connected to the support seat.

[0007] Preferably, the top of the support base is provided with an arc-shaped groove, and an arc-shaped elastic sponge pad is fixedly connected to the inner wall of the arc-shaped groove.

[0008] Preferably, the bottom of the support base is provided with a cross-shaped groove, and the inside of the thermos bottle is provided with an inner liner, the bottom of which is adapted to the arc-shaped groove.

[0009] Preferably, the bottom of the bottle base has a circular hole, and a fixing rod is fixedly connected to the inner wall of the circular hole.

[0010] Preferably, the outer surface of the thermos body near the bottom has a plurality of square grooves arranged in a circumferential array. A guide rod is fixedly connected to the opposite side of the inner wall of the square groove. A U-shaped block is slidably connected to the outer surface of the guide rod. The outer surface of the U-shaped block is slidably connected to the inside of the square groove. A return spring is provided on the outer surface of the guide rod. The return spring is fixedly connected to the U-shaped block and the thermos body respectively.

[0011] Preferably, a round rod is fixedly connected to one side of the two arms of the U-shaped block, and an L-shaped limiting block is rotatably connected to the outer surface of the round rod. Two torsion springs are symmetrically arranged on the outer surface of the round rod, and the two torsion springs are fixedly connected to the L-shaped limiting block and the U-shaped block respectively.

[0012] Preferably, the outer surface of the bottle base has multiple limiting grooves arranged in a circumferential array.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when the bottle base collides with the ground or tabletop, the inner liner inside the thermos bottle is subjected to a force, which in turn exerts a downward force on the support base. This causes the slider to slide downward inside the square groove, stretching the upper buffer spring and compressing the lower buffer spring, thus contracting the damper. Through the cooperation of the damper and the buffer spring, along with the arc-shaped elastic sponge pad, a certain buffering effect can be achieved, reducing the force on the inner liner. This prevents the inner liner from bursting due to strong force, thus avoiding the spillage of boiling water and preventing burns to the user.

[0015] 2. This utility model involves manually rotating the L-shaped limiting block outwards, causing it to rotate around the round rod at an appropriate angle. This causes the torsion spring to twist and apply a downward pulling force, which in turn causes the U-shaped block to slide downwards along the outer surface of the guide rod a suitable distance. Simultaneously, the return spring is stretched, and under the return force of the torsion spring, the L-shaped limiting block is inserted into the limiting groove. Then, the L-shaped limiting block is released, allowing the U-shaped block to slide upwards under the return force of the return spring. This simultaneously causes the L-shaped limiting block to move upwards a suitable distance, ensuring a tight fit between the L-shaped limiting block and the top of the inner wall of the limiting groove. In this way, if the threaded connection between the connecting ring and the thermos body slips or loosens, it can prevent the bottle base from detaching from the thermos body, thereby improving the protection of the inner liner.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Examples, such as Figure 1-4As shown, this utility model provides an explosion-proof and stable base for a thermos bottle, including: a thermos bottle body 1 and a bottle base 2. The bottle base 2 is located below the thermos bottle body 1. It also includes: a connecting ring 208, which is fixedly connected to the top of the bottle base 2. The connecting ring 208 is threadedly connected to the thermos bottle body 1. The inner wall of the connecting ring 208 has multiple square grooves 209 arranged in a circular array. The inner wall of the square grooves 209 is slidably connected to sliders 210. A support seat 204 is fixedly connected to one side of the multiple sliders 210. The support seat 204 is slidably connected to the connecting ring 208. A buffer spring 211 is fixedly connected to the opposite side of the sliders 210. One end of the two buffer springs 211 is fixedly connected to the opposite side of the inner wall of the square grooves 209. Multiple dampers 207 are fixedly connected in a circular array on the top of the bottle base 2. The multiple dampers 207 are all fixedly connected to the support seat 204.

[0025] Furthermore, such as Figure 1-4 As shown, the top of the support base 204 is provided with an arc-shaped groove, and an arc-shaped elastic sponge pad 205 is fixedly connected to the inner wall of the arc-shaped groove. The arc-shaped elastic sponge pad 205 provides a certain cushioning effect.

[0026] Furthermore, such as Figure 1-4 As shown, the bottom of the support base 204 is provided with a cross-shaped groove 206, and the inside of the thermos bottle body 1 is provided with an inner liner. The bottom of the inner liner is adapted to the arc-shaped groove. Through the above-mentioned arrangement, the water flowing on the outer wall of the inner liner can flow out from the bottom of the bottle base 2.

[0027] Furthermore, such as Figure 1-4 As shown, a round hole 201 is provided at the bottom of the bottle base 2, and a fixing rod 202 is fixedly connected to the inner wall of the round hole 201. The fixing rod 202 facilitates the rotation of the bottle base 2.

[0028] Furthermore, such as Figure 1-4 As shown, the outer surface of the thermos body 1 near the bottom has multiple square grooves 101 arranged in a circumferential array. A guide rod 102 is fixedly connected to the opposite side of the inner wall of the square groove 101. A U-shaped block 103 is slidably connected to the outer surface of the guide rod 102. The outer surface of the U-shaped block 103 is slidably connected to the inside of the square groove 101. A return spring 104 is provided on the outer surface of the guide rod 102. The return spring 104 is fixedly connected to the U-shaped block 103 and the thermos body 1 respectively. Through the above arrangement, the U-shaped block 103 can slide up and down along the outer surface of the guide rod 102, so that the return spring 104 can be compressed or stretched.

[0029] Furthermore, such as Figure 1-4As shown, a round rod 105 is fixedly connected to one side of the two arms of the U-shaped block 103. An L-shaped limiting block 106 is rotatably connected to the outer surface of the round rod 105. Two torsion springs 107 are symmetrically arranged on the outer surface of the round rod 105. The two torsion springs 107 are fixedly connected to the L-shaped limiting block 106 and the U-shaped block 103 respectively. Under the reset force of the torsion springs 107, the L-shaped limiting block 106 can rotate around the round rod 105 into the square groove 101.

[0030] Furthermore, such as Figure 1-4 As shown, the outer surface of the bottle base 2 is provided with multiple limiting grooves 203 in a circumferential array. With the above-mentioned arrangement, when the L-shaped limiting block 106 is inserted into the limiting groove 203, the bottle base 2 can be limited.

[0031] Working Principle: During use, when the bottle base 2 collides with the ground or tabletop, the inner liner inside the thermos bottle body 1 experiences a force, causing the inner liner to exert a downward force on the support base 204. This causes the slider 210 to slide downwards within the square groove 209, stretching the upper buffer spring 211 and compressing the lower buffer spring 211, thus contracting the damper 207. Through the cooperation of the damper 207 and the buffer spring 211, along with the arc-shaped elastic sponge pad 205, a certain buffering effect is achieved, reducing the force on the inner liner. This prevents the inner liner inside the thermos bottle body 1 from bursting due to strong force, thus avoiding the spillage of boiling water and preventing burns to the user. By manually moving the L-shaped limiting block 106 towards... The outer side is rotated so that it rotates around the round rod 105 at an appropriate angle, causing the torsion spring 107 to twist and apply a downward pulling force. This causes the U-shaped block 103 to slide down an appropriate distance along the outer surface of the guide rod 102, simultaneously stretching the return spring 104. Under the return force of the torsion spring 107, the L-shaped limiting block 106 is inserted into the interior of the limiting groove 203. Then, the L-shaped limiting block 106 is released, causing the U-shaped block 103 to slide upward under the return force of the return spring 104. Simultaneously, the L-shaped limiting block 106 is moved upward an appropriate distance, so that the L-shaped limiting block 106 is tightly fitted with the top of the inner wall of the limiting groove 203. In this way, if the threaded connection between the connecting ring 208 and the thermos body 1 slips and loosens, the bottle base 2 can be prevented from detaching from the thermos body 1, thereby improving the protection of the inner liner.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
