[0030] Reference Figure 1 to Figure 2 According to the first embodiment of the utility model, a lip balm tube includes a tube seat 100, a sliding seat 200, a rotating seat 300, a threaded transmission structure 400 and a one-way transmission structure 500. The tube seat 100 has a receiving groove 110 with an opening facing upward. The sliding seat 200 is slidably disposed in the receiving groove 110. The rotating seat 300 is rotatably disposed on the tube seat 100. The threaded transmission structure 400 is disposed on the sliding seat 200 and the rotating seat 300. Counterclockwise rotation of the rotating seat 300 can drive the sliding seat 200 to slide toward the opening direction of the receiving groove 110. The one-way transmission structure 500 is disposed on the tube seat 100 and the rotating seat 300. The one-way transmission structure 500 can limit the clockwise rotation of the rotating seat 300. When the user needs to extend the lipstick for use, the user can rotate the rotating seat 300 counterclockwise. During the rotation, the threaded transmission structure 400 can drive the sliding seat 200 to slide toward the opening direction of the receiving groove 110 to extend the lipstick. The one-way transmission structure 500 can limit the clockwise rotation of the rotating seat 300 so that the sliding seat 200 cannot be retracted, thereby reminding the user not to extend the lipstick too much, so that the user can only extend the lipstick according to the demand, so that the lipstick will not contaminate the tube seat 100 when it is retracted.

[0031] Specifically, the tube base 100 is roughly in the shape of a circular tube, the receiving groove 110 is in the shape of a cylindrical groove, and the opening is arranged upward, the rotating seat 300 can be arranged at one end of the tube base 100 away from the opening of the receiving groove 110, and the rotating seat 300 can be rotatably installed on the tube base 100, and the specific installation structure is not limited, the sliding seat 200 is arranged in the receiving groove 110, and the sliding seat 200 can slide along the depth direction of the receiving groove 110, the sliding seat 200 is used to set the lipstick body, and the solid lipstick can be carried by the sliding seat 200, the threaded transmission structure 400 is arranged on the sliding seat 200 and the rotating seat 300, and the specific transmission structure is not limited, and the one-way transmission structure 50 0 is arranged on the rotating seat 300 and the tube seat 100, the specific structure of the one-way transmission structure 500 is not limited, the one-way transmission structure 500 can limit the rotating seat 300 to rotate clockwise, and the specific limiting direction is limited according to the actual situation, so that the rotating seat 300 can only rotate counterclockwise. When rotating counterclockwise, the sliding seat 200 can be driven by the threaded transmission structure 400 to slide along the open end of the accommodating groove 110, so that the lipstick can be extended out of the tube seat 100. Through the above structure, the user can only operate the lipstick to extend but not to retract, so that the extended lipstick cannot be retracted into the tube seat 100 even if it is contaminated, and will not cause further contamination to the lipstick below.

[0032] Reference Figure 2 In some embodiments of the present invention, the rotating seat 300 has a first mounting groove 310, and one end of the tube seat 100 away from the opening of the receiving groove 110 is inserted into the first mounting groove 310, and the rotating seat 300 is coaxially arranged with the tube seat 100, and the rotating seat 300 can rotate around the axis of the tube seat 100. Specifically, the rotating seat 300 is cylindrical, the first mounting groove 310 is a circular groove body, the tube seat 100 can be matched and connected with the rotating seat 300, so that the rotating seat 300 can rotate around the axis of the tube seat 100, the structure is simple, and it is easy to drive.

[0033] Reference Figure 1 to Figure 2 In some embodiments of the utility model, the one-way transmission structure 500 includes a first ratchet 510 and a plurality of second ratchet teeth 520. The first ratchet teeth 510 are provided on the side wall of the tube seat 100, and a plurality of second ratchet teeth 520 are provided on the inner wall of the first mounting groove 310. The second ratchet teeth 520 are arranged at intervals around the first mounting groove 310. The first ratchet teeth 510 cooperate with the second ratchet teeth 520 to limit the clockwise rotation of the rotating seat 300.

[0034] Specifically, a first ratchet tooth 510 can be arranged on the side wall of the tube seat 100, and the first ratchet tooth 510 is extended vertically. A plurality of second ratchet teeth 520 are evenly spaced on the inner wall of the first mounting groove 310, and the second ratchet teeth 520 are also extended vertically. When the rotating seat 300 rotates counterclockwise, the inclination of the mating tooth surfaces of the first ratchet tooth 510 and the second ratchet tooth 520 is large and easy to disengage, so that the rotating seat 300 can rotate counterclockwise. On the contrary, when the rotating seat 300 rotates clockwise, the mating tooth surfaces of the first ratchet tooth 510 and the second ratchet tooth 520 cannot be easily disengaged, which can limit the rotation of the rotating seat 300, thereby limiting the inward sliding of the sliding seat 200.

[0035] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the tube seat 100 is provided with an elastic portion 120, and the elastic portion 120 is provided with a first ratchet 510. Specifically, the elastic portion 120 can be deformed relatively easily, so that the first ratchet 510 and the second ratchet 520 can cooperate smoothly, and the rotating seat 300 can easily rotate counterclockwise.

[0036] Reference Figures 1 to 3 In some embodiments of the present invention, the tube seat 100 is provided with a hollow groove 130, and the hollow groove 130 has a first transverse groove body 131, a vertical groove body 132 and a second transverse groove body 133, and the vertical groove body 132 is extended along the length direction of the tube seat 100, and the top of the vertical groove body 132 is connected to the right end of the first transverse groove body 131, and the bottom of the vertical groove body 132 is connected to the right end of the second transverse groove body 133, and an elastic part 120 is formed between the first transverse groove body 131, the second transverse groove body 133 and the vertical groove body 132. Through the above structure, the limiting ability of unidirectional rotation can be improved and the resistance when rotatable can be reduced.

[0037] Specifically, the first transverse groove body 131 and the second transverse groove body 133 can be arranged in parallel, and the first transverse groove body 131 and the second transverse groove body 133 can be arranged at intervals, and a vertical groove body 132 is arranged therebetween. By arranging the above-mentioned groove bodies, the tube wall therein can be easily deformed, and when the rotating seat 300 rotates clockwise, under the action of the first ratchet tooth 510 and the second ratchet tooth 520, the elastic part 120 can be deformed outward, thereby further jamming the first ratchet tooth 510 and the second ratchet tooth 520, which can further strengthen the degree of restriction. On the contrary, when the rotating seat 300 rotates counterclockwise, the elastic part 120 deforms inward, which facilitates the disengagement of the first ratchet tooth 510 and the second ratchet tooth 520, and can facilitate the rotation of the rotating seat 300.

[0038] Reference Figure 2In some embodiments of the utility model, an annular clamping groove 311 is provided on the inner side wall of the first installation groove 310, and an annular clamping portion 140 is provided on the outer side wall of the tube seat 100. The annular clamping groove 311 cooperates with the annular clamping portion 140 to prevent the tube seat 100 from axially separating from the rotating seat 300. The above structure can facilitate the assembly of the tube seat 100 and the rotating seat 300.

[0039] Specifically, the annular clamping portion 140 can be an annular buckle, and the annular clamping groove 311 can be snap-fitted with the annular clamping portion 140. After the snap-fitting, the rotating seat 300 and the tube seat 100 can rotate relative to each other, but cannot be axially disengaged. Through the above structure, the tube seat 100 and the rotating seat 300 can be easily assembled.

[0040] Reference Figure 1 to Figure 2 In some embodiments of the utility model, the threaded transmission structure 400 includes a transmission screw 410 and a transmission internal thread column 420. The transmission screw 410 is provided at the bottom of the sliding seat 200, and the transmission internal thread column 420 is provided on the rotating seat 300. The transmission screw 410 is threadedly connected with the transmission internal thread column 420. The bottom wall of the accommodating groove 110 is provided with an avoidance hole 111 for the transmission screw 410 to pass through, and the avoidance hole 111 can limit the rotation of the transmission screw 410. Specifically, the transmission screw 410 can be provided with a section, and the avoidance hole 111 can be set to a shape matching the transmission screw 410, so that the avoidance hole 111 can limit the rotation of the transmission screw 410. The transmission internal thread column 420 can be provided at the middle of the rotating seat 300, and the transmission screw 410 can be threadedly connected with the transmission internal thread column 420. Rotating the rotating seat 300 can enable the transmission screw 410 to move up and down.

[0041] It is understandable that the transmission screw 410 can be disposed on the rotating seat 300 , and the transmission internal thread column 420 can be disposed on the sliding seat 200 .

[0042] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the transmission screw 410 is provided with an upper limit portion 411 and a lower limit portion 412, the upper limit portion 411 is provided at the upper portion of the transmission screw 410, and the lower limit portion 412 is provided at the lower portion of the transmission screw 410, the upper limit portion 411 can abut against the bottom wall of the receiving groove 110, and the lower limit portion 412 can abut against the bottom of the sliding seat 200 to limit the sliding range of the sliding seat 200. This prevents the transmission screw 410 from falling off the working range.

[0043] Specifically, the upper limit portion 411 and the lower limit portion 412 can be snap buckles. When the transmission screw 410 moves up and down, the upper limit portion 411 can abut against the bottom wall of the accommodating groove 110 to limit the transmission screw 410 from further moving downward, and the lower limit portion 412 can abut against the bottom of the sliding seat 200 to limit the transmission screw 410 from further moving upward, so that the transmission screw 410 will not fall out of the working range.

[0044] Reference Figure 1 to Figure 2 In some embodiments of the present invention, the rotating seat 300 includes an operating seat 320 and a transmission seat 330. The operating seat 320 has a second mounting groove 321. The transmission seat 330 is rotatably arranged in the second mounting groove 321. A plurality of first transmission teeth 322 are arranged at intervals on the inner side wall of the second mounting groove 321. A plurality of second transmission teeth 331 are arranged on the outer side wall of the transmission seat 330. Rotating the operating seat 320 can make the first transmission teeth 322 cooperate with the second transmission teeth 331 to drive the transmission seat 330 to rotate. Through the above structure, a rotation virtual position can be formed, which can prevent the user from rotating the rotating seat 300 by mistake, resulting in the waste of lipstick sticking out.

[0045] Specifically, a second ratchet 520 is provided on the inner wall of the transmission seat 330, and the transmission seat 330 is matched with the tube seat 100 for transmission, and the operating seat 320 is matched with the transmission seat 330 for transmission. The user can rotate the operating seat 320, and the first transmission teeth 322 in the operating seat 320 are arranged at intervals. Similarly, the second transmission teeth 331 on the outer wall of the transmission seat 330 are also arranged at intervals. Therefore, when the operating seat 320 is rotated, there is a virtual position, and the first transmission tooth 322 needs to be rotated to the position of the second transmission tooth 331 before transmission can start. The virtual position set above can prevent the user from accidentally rotating the rotating seat 300, resulting in waste of lipstick.

[0046] Reference Figure 1 to Figure 2 In some embodiments of the present invention, a cover 600 is further included, which can be snap-fitted to the rotating seat 300 and cover the opening of the receiving groove 110. The cover 600 can fully protect the lipstick.
