Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to a portable thermos cup. Background Technology

[0002] A thermos is a container designed to maintain the temperature of liquids, whether hot or cold. It achieves this by using double-walled stainless steel walls and a vacuum layer, effectively preventing heat exchange between the inside and outside, thus keeping drinks at a comfortable temperature for a longer period.

[0003] Existing thermos cups generally consist of two parts: the cup body and the lid. The cup body and the lid are connected by threads. For portability, some thermos cups have a ring hinged to the lid to function as a handle.

[0004] The outer surface of existing thermos cups is mainly smooth and flat. This means that users can only grip the cup with their own strength. If the thermos cup becomes dirty or otherwise becomes very smooth, users will not be able to grip the cup well, which could lead to the risk of hot water spilling out. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides a portable thermos cup. It has the following beneficial effects:

[0018] 1. When gripping the body of the thermos, the bending sleeve causes the upper and lower ends of the bent sleeve to move the connecting rings. The connecting rings then cause the connecting cylinder to compress the wave spring. This allows the elastic force of the wave spring to be fed back to the bending sleeve through the connecting cylinder and the connecting rings, thus providing an internal supporting force when the hand grips the thermos, preventing the body from slipping.

[0019] 2. When taking out the thermos, by squeezing the pressing plate, the pressing rod is driven to squeeze the pin inserted inside the U-shaped connecting block, causing the pin to disengage from the U-shaped connecting block, thus limiting the contact of the U-shaped connecting block. After rotating the U-shaped connecting block to the appropriate angle, the pressing plate is released, allowing the pin to be inserted into the U-shaped connecting block under the action of the spring, thus limiting the U-shaped connecting block and preventing the thermos from shaking when lifting it.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0027] Example 1

[0028] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a portable thermos cup, including a cup body 1, a cup lid 3 at the top of the cup body 1, an extraction component 4 on the outer surface of the cup lid 3, and a gripping component 2 on the outer surface of the cup body 1. The gripping component 2 includes two fixing rings 201 fixedly connected to the outer surface of the cup body 1. Wave springs 202 are fixedly connected inside each of the two fixing rings 201. A connecting cylinder 203 is fixedly connected to the end of the wave spring 202 away from the fixing ring 201. A connecting ring 204 is fixedly connected to the end of the connecting cylinder 203 away from the fixing ring 201. A bending sleeve 205 is fixedly connected to the end of the connecting ring 204 away from the connecting cylinder 203.

[0029] Specifically, the fixed ring 201 has a cavity inside, the wave spring 202 is fixedly connected in the cavity, and the fixed ring 201 has an annular groove communicating with the cavity on the side near the connecting cylinder 203. The end of the connecting cylinder 203 near the fixed ring 201 slides in the annular groove.

[0030] Furthermore, the bending sleeve 205 is made of soft rubber. When not gripping the bending sleeve 205, it can bend outward under the pressure of the two wave springs 202. When gripping the thermos cup body 1, the bending sleeve 205 causes the upper and lower ends of the originally bent bending sleeve 205 to move the connecting ring 204 respectively. The connecting ring 204 drives the connecting cylinder 203 to compress the wave spring 202, so that the elastic force of the wave spring 202 is fed back to the bending sleeve 205 through the connecting cylinder 203 and the connecting ring 204, so that the hand has an internal supporting force when gripping, thereby preventing the cup body 1 from slipping.

[0031] Example 2

[0032] Reference Figure 1 , Figure 3 and Figure 4 This is the second embodiment of the present invention. Based on the previous embodiment, the extracted component 4 includes a U-shaped connecting block 401 hinged to the outer surface of the cup lid 3 by a pin 405. Each U-shaped connecting block 401 has a pressing rod 406 inserted inside. A compression spring 404 is fixedly connected inside the cup lid 3. A pin 405 is fixedly connected to one end of the compression spring 404 near the pressing rod 406.

[0033] Specifically, the U-shaped connecting block 401 has two protrusions 402 on the side near the cup lid 3. The outer surface of the protrusions 402 has an arc-shaped surface. The outer surface of the cup lid 3 has a circular groove that matches the protrusions 402. The end of the extrusion rod 406 away from the cup lid 3 is fixedly connected to the pressing piece 403. The pin 405 and the extrusion rod 406 have the same diameter. The cup lid 3 and the U-shaped connecting block 401 both have circular holes. The end of the compression spring 404 away from the extrusion rod 406 is fixedly connected to the inner wall of the circular hole. The end of the pin 405 away from the cup lid 3 is always kept inside the circular hole.

[0034] Furthermore, by squeezing the pressing plate 403, the pressing rod 406 is driven to squeeze the pin 405 inserted inside the U-shaped connecting block 401, causing the pin 405 to disengage from the U-shaped connecting block 401, thereby limiting the contact of the U-shaped connecting block 401. After rotating the U-shaped connecting block 401 to a suitable angle, the pressing plate 403 is released, allowing the pin 405 to be inserted into the U-shaped connecting block 401 under the action of the spring, thereby limiting the U-shaped connecting block 401 and preventing the thermos from shaking when lifting it.

[0035] Working principle: When using the thermos, unscrew the lid 3, which is threaded onto the outer surface of the cup body 1, to remove it. Add water to the thermos and then screw the lid 3 back onto the cup body 1. When lifting the thermos, the pressing plate 403 is squeezed, which in turn drives the pressing rod 406 to press the pin 405 inserted into the U-shaped connecting block 401, causing the pin 405 to disengage from the U-shaped connecting block 401. This achieves contact limitation of the U-shaped connecting block 401. After rotating the U-shaped connecting block 401 to a suitable angle, the pressing plate 403 is released, allowing the pin 405 to insert into the U-shaped connecting block 401 under the action of the spring. This achieves the limiting of the U-shaped connecting block 401, preventing the thermos from shaking when lifting it. When it is necessary to grasp the thermos body 1, by grasping the bending sleeve 205, the upper and lower ends of the originally bent bending sleeve 205 respectively drive the connecting ring 204 to move. The connecting ring 204 drives the connecting cylinder 203 to compress the wave spring 202, so that the elastic force of the wave spring 202 is fed back to the bending sleeve 205 through the connecting cylinder 203 and the connecting ring 204, so that the hand has an internal supporting force when gripping, thereby preventing the cup body 1 from slipping, and finally realizing the convenience of carrying and gripping the thermos.
