A steaming frame

Abstract

This utility model relates to a steaming frame, including a lower frame and an upper frame. A connecting plate is installed between the lower and upper frames. Universal wheels are installed at the four corners of the bottom of the lower frame. Two parallel limiting plates are installed on both sides of the upper surface of the upper frame. Multiple lower and upper brackets are slidably mounted on the outer surfaces of the two limiting plates. Upright plates are installed on both sides of the upper surface of the upper frame, positioned between the two limiting plates. An installation groove is formed on the outer surface of the upright plate, and a scissor-type telescopic frame is installed inside the groove via a drive mechanism. Multiple lower brackets are connected to the scissor-type telescopic frame via connecting shafts. The drive mechanism extends and retracts the scissor-type telescopic frame, which in turn causes multiple upper brackets to rise and fall synchronously. Therefore, when placing a perforated tray on the upper bracket, its height can be lowered, avoiding the need to raise an arm, thus improving operational safety and preventing spillage of the poria cocos, making it easier to use.

Description

Technical Field

[0001] This utility model relates to the field of Poria cocos processing technology, specifically a steaming frame. Background Technology

[0002] Poria cocos is a fungus that parasitizes the roots of pine trees. It resembles a sweet potato in shape, with a dark brown outer skin and a white or pink interior. It is used medicinally. As a traditional Chinese medicine, it is sweet and bland in taste, neutral in nature, and non-toxic. It enters the heart, spleen, lung, and kidney meridians, and has the effects of promoting diuresis and eliminating dampness, benefiting the spleen and stomach and protecting the kidneys, calming the mind and promoting body fluid production. It is widely used in various Chinese medicine prescriptions. The processing steps of Poria cocos include sweating, washing, steaming, cutting into pieces, drying, and packaging. Steaming softens the Poria cocos, making it easier to process, and enhances its spleen-strengthening and diuretic effects.

[0003] When steaming Poria cocos, it is first laid flat on a perforated tray, then the perforated trays are placed layer by layer in a steaming frame, and finally the steaming frame is pushed into the steamer for steaming. However, because the steaming frame is relatively tall and has many layers, the height of the steaming frame may be higher than the height of short workers. This means that when placing or removing perforated trays from the upper layers of the steaming frame, workers need to raise their arms overhead. This method of raising arms not only makes it easy for workers to lose their balance and increases the risk of slipping, but also, if they are not careful during the operation, the Poria cocos may spill from the tray. Utility Model Content

[0004] The purpose of this invention is to provide a steaming frame that facilitates the placement and removal of perforated trays from higher levels, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A steaming frame includes a lower frame and an upper frame. A connecting plate is installed between the lower and upper frames. Universal wheels are installed at the four corners of the bottom of the lower frame. Two parallel limiting plates are installed on both sides of the upper surface of the upper frame. Multiple lower and upper brackets are slidably mounted on the outer surfaces of the two limiting plates. Upright plates are installed on both sides of the upper surface of the upper frame, and these upright plates are positioned between the two limiting plates. An installation groove is formed on the outer surface of the upright plate. A scissor-type telescopic frame is installed inside the installation groove via a drive mechanism. Multiple lower brackets are connected to the scissor-type telescopic frame via connecting shafts. A transmission mechanism is provided between the two sets of drive mechanisms. A connecting plate is installed on the outer surfaces of the multiple upper brackets, and the bottom of the connecting plate is connected to the outer surface of the uppermost lower bracket.

[0006] As can be seen, by driving the scissor-type telescopic frame to extend and retract through the drive mechanism, multiple lower brackets can be raised and lowered proportionally at the same time. When multiple lower brackets are raised and lowered proportionally, multiple upper brackets can be raised and lowered synchronously. Therefore, when placing the hollowed-out tray on the upper bracket, its height can be lowered, avoiding the operation method of raising the arm high, thereby improving the safety of operation and ensuring that the Poria cocos does not spill, making it convenient to use.

[0007] Furthermore, the drive mechanism includes a threaded rod with a pair of reverse threads rotatably mounted inside the mounting slot. Nut seats are mounted on both reverse threads of the threaded rod. Hinge blocks are mounted on the outer surface of the nut seats. The ends of the two hinge blocks are respectively hinged to the two ends of the bottom of the scissor telescopic frame.

[0008] Furthermore, the transmission mechanism includes two fixed blocks respectively mounted on the outer surfaces of the two upright plates, a rotating shaft rotatably mounted between the two fixed blocks, worm gears provided on both sides of the outer surface of the rotating shaft, and the ends of the two threaded rods extending to the outer side of the upright plates and equipped with worm wheels, which mesh with the worm gears.

[0009] Furthermore, one end of the rotating shaft extends through to the outside of the fixed block and is fitted with a turntable, the outer surface of which is provided with a handle.

[0010] Furthermore, the surface of the turntable has through holes, and the handle is inserted into the through holes. Limit blocks are installed at both ends of the handle along its length.

[0011] Furthermore, a reinforcing frame is installed on the top of the four limiting plates and the two upright plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses a drive mechanism to extend and retract a scissor-type telescopic frame, which can simultaneously raise and lower multiple lower brackets proportionally. When multiple lower brackets are raised and lowered proportionally, multiple upper brackets can be raised and lowered synchronously. Therefore, when placing a hollowed-out tray on the upper bracket, its height can be lowered, avoiding the need to raise one's arm, thereby improving the safety of operation and ensuring that the Poria cocos does not spill, making it convenient to use.

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0023] Please see Figure 1-5One embodiment provided by this utility model:

[0024] A steaming frame includes a lower frame 100 and an upper frame 101. A connecting plate 102 is installed between the lower frame 100 and the upper frame 101. Universal wheels 111 are installed at the four corners of the bottom of the lower frame 100, facilitating movement of the steaming frame. Two parallel limiting plates 103 are installed on both sides of the upper surface of the upper frame 101. Multiple lower brackets 104 and multiple upper brackets 105 are slidably mounted on the outer surfaces of the two limiting plates 103. Vertical plates 106 are installed on both sides of the upper surface of the upper frame 101, positioned between the two limiting plates 103. The outer surface of the upright plate 106 is provided with a mounting groove 107. Inside the mounting groove 107, a scissor-type telescopic frame 108 is installed through a drive mechanism 200. Multiple lower brackets 104 are connected to the scissor-type telescopic frame 108 through a connecting shaft 109. A transmission mechanism 300 is provided between the two sets of drive mechanisms 200. Through the transmission mechanism 300 and the two sets of drive mechanisms 200, the scissor-type telescopic frames 108 on both sides retract downwards at the same time. Therefore, the height of the upper bracket 105 can be lowered, making it easier to place and retrieve the hollowed-out tray on the upper bracket 105. This avoids the operation method of raising the arm high, thereby improving the safety of operation and ensuring that the Poria cocos does not spill, making it convenient to use. A connecting plate 110 is mounted on the outer surface of multiple upper brackets 105, and the bottom of the connecting plate 110 is connected to the outer surface of the uppermost lower bracket 104. When multiple lower brackets 104 are raised and lowered proportionally, multiple upper brackets 105 are raised and lowered synchronously without changing their spacing, thus facilitating the placement and removal of the perforated tray. A reinforcing frame 600 is mounted on the top of the four limiting plates 103 and the two upright plates 106. The reinforcing frame 600 strengthens the overall strength of the steaming frame and improves its load-bearing capacity.

[0025] Please see Figure 2 , Figure 3 and Figure 5The drive mechanism 200 includes a threaded rod 201 with a pair of reverse threads rotatably mounted inside the mounting groove 107. Nut seats 202 are mounted on both reverse threads of the threaded rod 201. Hinge blocks 203 are mounted on the outer surface of the nut seats 202. The ends of the two hinge blocks 203 are respectively hinged to the two ends of the bottom of the scissor telescopic frame 108. When the threaded rod 201 rotates, due to the reverse threads, the two nut seats 202 can be driven to move in opposite directions along the length of the threaded rod 201 at the same time, thereby achieving the purpose of driving the scissor telescopic frame 108 to extend and retract. The transmission mechanism 300 includes two fixed blocks 301 respectively mounted on the outer surfaces of two upright plates 106. A rotating shaft 302 is rotatably mounted between the two fixed blocks 301. Worms 303 are provided on both sides of the outer surface of the rotating shaft 302. The ends of two threaded rods 201 extend to the outer side of the upright plate 106 and are equipped with worm wheels 304. The worm wheels 304 are meshed with the worms 303. When the rotating shaft 302 is rotated, it can drive the two worms 303 on its surface to rotate. Since the worms 303 are meshed with the worm wheels 304, it can drive the two threaded rods 201 to rotate simultaneously, and realize the purpose of simultaneous extension and retraction of the scissor-type telescopic frames 108 on both sides. Furthermore, the worms 303 and worm wheels 304 have good self-locking properties, which can ensure that the lower bracket 104 will not slide down due to gravity when carrying the hollowed-out tray, thus ensuring good stability.

[0026] Please see Figure 1 and Figure 3 One end of the rotating shaft 302 extends through to the outside of the fixed block 301 and is fitted with a turntable 400. A handle 401 is provided on the outer surface of the turntable 400. The turntable 400 and the handle 401 allow for easier rotation of the rotating shaft 302. A through hole 500 is provided on the surface of the turntable 400. The handle 401 is inserted into the through hole 500. Limiting blocks 501 are installed at both ends of the handle 401 along its length. The handle 401 can slide within the through hole 500, preventing it from protruding outwards and affecting the entry of the steaming frame into the steaming chamber. The limiting blocks 501 on both sides of the handle 401 can limit its movement, preventing the handle 401 from detaching from the through hole 500.

[0027] The specific workflow and working principle of this device are as follows.

[0028] In use, first turn the handle 401 to drive the shaft 302 to rotate. Since the worm 303 and worm wheel 304 are meshed, they can simultaneously drive the threaded rods 201 on both sides to rotate. Due to the reverse thread setting, the two nut seats 202 can be driven to move away simultaneously, thus driving the scissor-type telescopic frames 108 on both sides to retract simultaneously. At this time, the height of the upper bracket 105 is reduced, and the hollow tray containing Poria cocos can be easily placed on the upper brackets 105 on both sides. Then, turn the handle 401 in the opposite direction to drive the two threaded rods 201 to rotate in the opposite direction simultaneously, and cause the two nut seats 202 on the surface of the threaded rods 201 to move inward simultaneously, so that the scissor-type telescopic frames 108 on both sides extend upward simultaneously, thereby causing multiple lower brackets 104 to rise proportionally. When there is enough space between two adjacent lower brackets 104, the hollow tray containing Poria cocos is placed on the lower brackets 104 on both sides. Then, the upper frame 101 is pushed into the steaming chamber for steam cooking by the casters 111.

[0029] After steaming, first remove the perforated tray on the lower rack 104, then lower the height of the upper rack 105 and remove the perforated tray on it. This avoids the need to raise your arm, thus improving the safety of the operation and ensuring that the Poria cocos does not spill, making it easier to use.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
