For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0014] In a first aspect, the present invention provides a foot.

[0015] The foot provided by the present invention is used to support a box body. As shown in combination with Figure 1 and Figure 2 , the foot provided by the present invention includes a fixed seat 100, a foot rod 200, a driving bevel gear 300 and a driven bevel gear assembly 400.

[0016] The fixed seat 100 is arranged at the bottom of the box body. The foot is fixed to the bottom of the box body by means of the fixed seat 100.

[0017] The driven bevel gear assembly 400 is rotatably arranged on the fixed seat 100, and the driven bevel gear assembly 400 is arranged horizontally.

[0018] The foot rod 200 is movably arranged on the driven bevel gear assembly 400, and both ends of the foot rod 200 extend to the upper and lower sides of the fixed seat 100. The first end of the foot rod 200 contacts the ground and plays a supporting role, and the second end of the foot rod extends towards the side where the box body is located.

[0019] The driving bevel gear 300 is vertically arranged, and the driving bevel gear 300 is meshed and connected with the driven bevel gear assembly 400.

[0020] Among them, by rotating the driving bevel gear 300, the driven bevel gear assembly 400 can be driven to rotate, so that the foot rod 200 moves up and down in the vertical direction, changing the height of the foot. The driving bevel gear 300 is meshed and connected with the driven bevel gear assembly 400 and perpendicular to each other, which can change the transmission direction of force, and convert the force rotating in the horizontal direction applied to the driving bevel gear 300 into the force rotating in the vertical direction of the foot rod 200, so as to realize the lifting of the foot rod 200.

[0021] In the case of adopting the above technical solution, for the foot provided by the present invention, by rotating the driving bevel gear 300, the driven bevel gear assembly 400 can be driven to rotate, so that the foot rod 200 moves up and down in the vertical direction to adjust the height of the foot. In this way, for the foot provided by the present invention, only by rotating the driving bevel gear 300 can the height of the foot be adjusted, without loosening the fastening nut and adjusting the height of the foot and then tightening the fastening nut as in the related art. The adjustment method of the foot in the present invention is simple and easy to implement, which is beneficial to improving the adjustment efficiency.

[0022] In this preferred embodiment, in combination with Figure 3 As shown, the driven bevel gear assembly 400 includes a driven bevel gear 401 and a nut 402. A fixing hole is provided at the center of the driven bevel gear 401, and the nut 402 is arranged in the fixing hole. Among them, the foot rod 200 includes a threaded portion, and the nut 402 is threadedly connected with the threaded portion of the foot rod 200. It can be understood that the nut 402 includes an internal thread, the outer surface of the threaded portion is provided with a thread, and the nut 402 is sleeved on the threaded portion of the foot rod 200 through the internal thread connection. Since the nut 402 is arranged in the fixing hole of the driven bevel gear 401, the foot rod 200 can be arranged on the driven bevel gear 401 through the nut 402.

[0023] With such a setting, the nut is sleeved on the threaded portion, and then the driven bevel gear 401 is sleeved on the nut, and the assembly of the driven bevel gear assembly and the foot rod 200 can be completed, which is beneficial to simplifying the assembly process and improving the assembly efficiency. In addition, the foot rod 200 is directly connected with the nut 402, and the nut bears the wear caused by the up and down movement of the foot rod 200. When the nut is damaged, the nut can be directly replaced without replacing the driven bevel gear, which is beneficial to reducing the maintenance cost of the foot.

[0024] In this preferred embodiment, in combination with Figure 3As shown, the fixing hole of the driven bevel gear 401 is set as a polygonal hole, and the nut is set as a polygonal nut adapted to the polygonal hole, so that the polygonal nut can be movably arranged up and down in the polygonal hole. By setting the fixing hole of the driven bevel gear 401 as a polygonal hole and the nut as a polygonal nut adapted to the polygonal hole, when the driven bevel gear 401 is driven to rotate in the horizontal direction, the polygonal nut can rotate synchronously with the driven bevel gear 401. In addition, when the foot lever 200 moves upward, the polygonal nut can be pushed upward under the drive of the foot lever 200, so that the upper surface of the polygonal nut contacts the cover plate of the fixed seat 100, which is beneficial to reducing the contact area between the driven bevel gear assembly and the cover plate, thereby reducing the resistance received when the driven bevel gear assembly rotates.

[0025] Preferably, in combination with Figure 3 As shown, the nut is set as a hexagonal nut, and the fixing hole of the driven bevel gear 401 is set as a hexagonal hole matching the hexagonal nut. The hexagonal nut is cheap and easy to obtain. By setting the nut as a hexagonal nut, not only can the above functions be satisfied, but also it is beneficial to reduce the cost of the foot.

[0026] In this preferred embodiment, in combination with Figure 1 As shown, the free end of the driving bevel gear 300 is exposed outside the fixed seat body 101, and an operation hole is provided at the free end of the driving bevel gear 300. By exposing the free end of the driving bevel gear 300 outside the fixed seat body 101, an operator can directly insert a tool such as a screwdriver into the operation hole to adjust the height of the foot, which is convenient for adjustment.

[0027] Preferably, in combination with Figure 3 As shown, the lower surface of the driven bevel gear assembly 400 is provided with a first set of teeth, and the side of the driving bevel gear 300 facing the driven bevel gear assembly 400 is provided with a second set of teeth. The first set of teeth and the second set of teeth are meshed and connected.

[0028] In this preferred embodiment, in combination with Figure 2 、 Figure 4 and Figure 5 As shown, the fixed seat 100 includes a fixed seat body 101 and a cover plate 102. The fixed seat body 101 is provided with a fixing groove 1011 with an upward opening, and the driven bevel gear assembly 400 is arranged in the fixing groove 1011. The cover plate 102 is fixedly arranged at the opening of the fixing groove 1011, and the cover plate 102 contacts the upper surface of the driven bevel gear assembly 400.

[0029] Through the cooperation of the fixing groove 1011 and the cover plate 102, the driven bevel gear assembly 400 can be limited in the fixing groove 1011 to ensure that the driven bevel gear assembly 400 is meshed and connected with the driving bevel gear 300 and rotates stably in the fixing groove 1011. Specifically, the inner diameter of the fixing groove 1011 matches the outer diameter of the driven bevel gear assembly 400, so as to avoid the displacement of the driven bevel gear assembly 400 in the horizontal direction and ensure the stable transmission of the driven bevel gear assembly 400. The cover plate 102 contacts the upper surface of the driven bevel gear assembly 400, which can limit the displacement of the driven bevel gear assembly 400 in the vertical direction and further ensure the stable transmission of the driven bevel gear assembly 400.

[0030] In this preferred embodiment, as shown in Figure 4 the fixing seat body 101 is further configured with a receiving channel 1012, and the receiving channel 1012 communicates with the fixing groove 1011 and the outside of the fixing seat body 101 respectively. Among them, the driving bevel gear 300 is disposed in the receiving channel 1012. By providing the receiving channel 1012 on the fixing seat body 101, it is convenient to install the driving bevel gear 300, so that the first end of the driving bevel gear 300 extends into the fixing groove 1011 and is meshed and connected with the driven bevel gear 401, and the second end of the driving bevel gear 300 extends to the outside of the fixing seat body 101.

[0031] Preferably, the inner diameter of the receiving channel 1012 matches the outer diameter of the driving bevel gear 300. With this setting, it can ensure that the driving bevel gear 300 rotates stably in the receiving channel 1012 and avoid the displacement of the driving bevel gear 300 in its radial direction.

[0032] Preferably, a first channel wall is provided on one side of the receiving channel 1012 close to the driven bevel gear 401, and the upper edge of the first channel wall is lower than the upper edge of the driving bevel gear 300. When the driving bevel gear 300 is installed in the receiving channel 1012, the first end side of the driving bevel gear 300 contacts the first channel wall. Among them, teeth are provided on the first end side of the driving bevel gear. With this setting, it is convenient for the driving bevel gear 300 to be meshed and connected with the driven bevel gear 401.

[0033] Preferably, as shown in Figure 2As shown, the driving bevel gear 300 includes a first part and a second part that are connected to each other. Teeth are provided on the end face of the first part away from the second part, and an operation hole is provided on the cross-section of the second part away from the first part, wherein the outer diameter of the first part is greater than the outer diameter of the second part. A limiting flange is provided on the side of the accommodation channel 1012 away from the driven bevel gear 401. The end face of the first part close to the second part contacts the inner wall surface of the limiting flange. The end face of the first part away from the second part contacts the first channel wall. The position of the driving bevel gear 300 along its axial direction can be defined by the first channel wall and the limiting flange, preventing the driving bevel gear 300 from displacing along its axial direction, and further ensuring the stable rotation of the driving bevel gear 300 in the accommodation channel 1012.

[0034] In this preferred embodiment, in combination with Figure 2 As shown, a clamping groove 1013 and a clamping buckle 1014 are respectively provided on both sides of the fixing groove 1011, and a first clamping block 1021 and a second clamping block 1022 are respectively provided on both sides of the cover plate 102. The first clamping block 1021 is adapted to be inserted into the clamping groove 1013, and the second clamping block 1022 is adapted to be clamped into the clamping buckle 1014. Insert the first clamping block 1021 of the cover plate 102 into the clamping groove 1013, and then clamp the second clamping block 1022 of the cover plate 102 into the clamping buckle 1014, and the cover plate 102 can be fixed at the opening of the fixing groove 1011, which is relatively easy to install.

[0035] Preferably, a first avoidance hole is formed at the bottom of the fixing groove 1011, a second avoidance hole is correspondingly formed on the cover plate 102, the lower end of the bottom foot rod 200 passes through the first avoidance hole and extends to the lower side of the fixing seat 100, and the upper end of the bottom foot rod 200 passes through the second avoidance hole and extends to the upper side of the fixing seat 100.

[0036] Preferably, a chassis is provided at the lower end of the bottom foot rod 200, and the chassis is used to contact the ground. By providing the chassis, the contact area between the bottom foot rod 200 and the ground can be increased, thereby improving the stability of the support of the bottom foot rod 200.

[0037] Preferably, the connection method between the fixing seat and the box body includes welding, bonding, connection by a connecting piece or bolt connection, which can be flexibly set according to requirements.

[0038] In a second aspect, the present invention provides a bottom foot assembly.

[0039] In combination with Figure 6 and Figure 7As shown in the figure, the foot component provided by the present invention includes a first foot 500, a second foot 600 and a transmission rod 700. The first foot 500 and the second foot 600 are the feet in any of the above embodiments. It can be understood that since the first foot 500 and the second foot 600 are the feet in any of the above embodiments, the first foot 500 and the second foot 600 include all the structural features and beneficial effects of the above feet, which will not be elaborated here one by one. The first foot 500 includes a first fixing seat 501. The first fixing seat 501 is provided with an avoidance hole, and the first fixing seat 501 is the fixing seat in any of the above embodiments. The second foot 600 includes a second driving bevel gear 601, and the second driving bevel gear 601 is the driving bevel gear 300 in any of the above embodiments. The first end of the transmission rod 700 is connected to the second driving bevel gear 601, and the second end passes through the avoidance hole and extends to the first side of the first fixing seat 100.

[0040] Since the first foot 500 and the second foot 600 are the feet in any of the above embodiments, by rotating the driving bevel gears of the first foot 500 and the second foot 600, the heights of the first foot 500 and the second foot 600 can be adjusted. The foot component provided by the present invention only needs to rotate the driving bevel gears of the first foot 500 and the second foot 600 to adjust the foot component to be horizontal, without the need to loosen the fastening nut and adjust the height of the foot and then tighten the fastening nut as in the related art. The adjustment method of the foot component provided by the present invention is simple and easy to implement, which is beneficial to improving the adjustment efficiency. In addition, since the first end of the transmission rod 700 is connected to the second driving bevel gear 601 and the second end extends to the first side of the first fixing seat 100, the user can adjust the heights of the first foot and the second foot on the side where the first foot 500 is located without having to walk back and forth, which is more convenient.

[0041] Preferably, a second operation hole is formed at the free end of the second driving bevel gear 601, and the second operation hole is the operation hole in any of the above embodiments. The shape of the first end of the transmission rod 700 matches the shape of the second operation hole, and the first end of the transmission rod 700 is adapted to be inserted into the second operation hole. In this way, the connection between the transmission rod 700 and the second driving bevel gear is more reliable, and the second driving bevel gear can be rotated synchronously with the transmission rod 700, reducing the risk of the transmission rod 700 falling off.

[0042] Preferably, the first end of the transmission rod 700 is connected to the second operation hole by welding, bonding or a connecting piece. In this way, the firmness of the connection between the transmission rod 700 and the second driving bevel gear can be further improved.
