Description

Technical Field

[0001] This utility model relates to the field of pressure vessels, specifically a pressure vessel locking structure for medical waste collection. Background Technology

[0002] Pressure vessels for medical waste collection are specially designed sealed containers for the safe temporary storage and transportation of high-risk medical waste (such as infectious, chemical, or sharps waste). They are typically made of high-strength stainless steel or corrosion-resistant composite materials. Their design must comply with international medical waste treatment standards (such as WHO or EPA regulations), and they must be leak-proof, puncture-proof, pressure-resistant, and sterilization-capable. Existing pressure vessel bodies and lids require a locking mechanism for secure fastening.

[0003] For example, patent announcement number CN217130315U discloses a pressure vessel locking structure, including a tank body and a cover body that are sealed to each other. A first protruding ring is fixedly provided on the outer side of one end of the tank body near the cover body, and a second protruding ring that mates with the first protruding ring is fixedly provided on the side of the cover body near the tank body. The first and second protruding rings are locked together by at least two sets of locking components. The locking components include a translation mechanism and a swinging component. The swinging component includes a connecting rod, two lugs, and a fixed shaft plate. The fixed shaft plate is fixedly mounted on the cover body or tank body, and the middle of the two lugs is rotatably connected to the fixed shaft plate. One end of the two lugs is provided with a slot. The translation mechanism includes a fixed guide rail and a slide block slidably mounted on the guide rail. One end of the connecting rod is hinged to the slide block, and the other end is hinged to the end of the two lugs away from the slot. This device can lock the pressure vessel without manual intervention and has good applicability.

[0004] However, the above-mentioned technology directly fixes the locking component to the can lid, resulting in a large weight of the can lid. After the can body and the can lid are unlocked, it is difficult to manually remove the can lid. Therefore, the market urgently needs to develop a pressure vessel locking structure for medical waste collection to help people solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a locking structure for pressure vessels used in the collection of medical waste, so as to solve the problem mentioned in the background art that the locking components are directly fixed to the can lid, resulting in a large weight of the can lid and difficulty in manually removing the can lid after the can body and the can lid are unlocked.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure vessel locking structure for medical waste collection, comprising a tank body, a first connecting ring fixedly connected to the upper end of the tank body, a tank cover connected to the upper end of the tank body, a second connecting ring fixedly connected to the lower end of the tank cover, a rotating seat fixedly connected to the middle of the upper end of the tank cover, a screw rotatably connected to the upper end of the rotating seat, a C-shaped support frame provided at the upper end of the tank cover, the lower ends of both sides of the C-shaped support frame extending to the lower ends of both sides of the first connecting ring and fixedly connected to rectangular clamping blocks, an internally threaded tube fixedly connected to the middle of the upper end of the C-shaped support frame, and a handwheel fixedly connected after the upper end of the screw passes through the internally threaded tube.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figure 1-4This utility model provides an embodiment of a pressure vessel locking structure for medical waste collection, comprising a tank body 1, a first connecting ring 102 fixedly connected to the upper end of the tank body 1, a tank cover 2 connected to the upper end of the tank body 1, a second connecting ring 201 fixedly connected to the lower end of the tank cover 2, a rotating seat 202 fixedly connected to the middle of the upper end of the tank cover 2, a screw 4 rotatably connected to the upper end of the rotating seat 202, a C-shaped support frame 3 provided at the upper end of the tank cover 2, the lower ends of both sides of the C-shaped support frame 3 extending to the lower ends of both sides of the first connecting ring 102 and fixedly connected to rectangular clamping blocks 301, an internally threaded tube 305 fixedly connected to the middle of the upper end of the C-shaped support frame 3, and a handwheel 401 fixedly connected to the upper end of the screw 4 after passing through the internally threaded tube 305. The first connecting ring 102 and the second connecting ring 201 are connected... A sealing ring 104 is provided, which is fixedly connected to the upper end face of the first connecting ring 102. The screw 4 is threadedly connected to the internal threaded tube 305. A circular limiting groove 203 is provided inside the rotating seat 202. The lower end of the screw 4 is inserted into the circular limiting groove 203 and fixedly connected to the limiting cylinder 402. When the can cover 2 is lowered and closed with the can body 1, the screw 4 is driven to rotate by the handwheel 401. The screw 4 is threadedly connected to the internal threaded tube 305, so that when the screw rotates, it drives the C-shaped support frame 3 to rise. The rectangular pressing blocks 301 on both sides of the C-shaped support frame 3 press against the lower end face of the second connecting ring 201 and press down the rotating seat 202 with the screw 4, so that the first connecting ring 102 and the second connecting ring 201 are pressed together and sealed by the sealing ring 104.

[0020] Please see Figure 3 The first connecting ring 102 has wing plates 105 fixedly connected to the middle of both ends of the first connecting ring 102. The upper middle of both wing plates 105 is fixedly connected to positioning pins 106. The second connecting ring 201 has positioning plates 204 fixedly connected to the middle of both ends of the second connecting ring 201. The middle of both positioning plates 204 is provided with positioning through holes 205. The two positioning pins 106 are respectively inserted into the two positioning through holes 205. When the can lid 2 is placed on the can body 1, it is positioned by inserting the positioning pins 106 into the positioning through holes 205 respectively.

[0021] Please see Figure 2 and Figure 4A rotating support seat 101 is fixedly connected to the upper end of one side of the tank body 1. A fixed shaft 303 is fixedly connected to the lower end of the side of the C-shaped support frame 3 adjacent to the rotating support seat 101. The lower end of the fixed shaft 303 passes through the middle of the rotating support seat 101 and is fixedly connected to a limiting circular plate 304. The rotating support seat 101 provides overall support for the C-shaped support frame 3 and the tank cover 2 inside it. When the screw 4 is rotated by the handwheel 401, the tank cover 2 is lowered and closes with the tank body 1. At this time, the screw 4 is rotated by the handwheel 401 again, and the descent of the tank cover 2 is blocked, thereby raising the C-shaped support frame 3. Rectangular limiting grooves 103 are provided in the middle of both sides of the lower end face of the first connecting ring 102. Rectangular limiting grooves are fixedly connected to the inner side of the upper end face of the two rectangular clamping blocks 301. When the C-shaped support frame 3 is raised, the two rectangular limiting blocks 302 are inserted into the two rectangular limiting grooves 103 respectively, so that the C-shaped support frame 3 and the first connecting ring 102 are limited and connected. When it is necessary to separate the can lid 2, the C-shaped support frame 3 is lowered first by rotating the handwheel 401 in the opposite direction and the rectangular pressing block 301 at the lower end of one side is lowered onto the rotating support seat 101. At the same time, the rectangular limiting block 302 is disengaged from the rectangular limiting groove 103. Then, when the handwheel 401 continues to rotate, the screw 4 drives the can lid 2 to be raised and the positioning pin 106 is disengaged from the positioning through hole 205. At this time, by pushing the C-shaped support frame 3 to rotate to one side through the fixed shaft 303, the C-shaped support frame 3 can drive the can lid 2 to be deflected to one side and moved out of the upper end of the can body 1.

[0022] Working principle: In use, first align the can lid 2 with the can body 1, and initially position it by inserting the positioning pin 106 into the positioning through hole 205 of the positioning plate 204. Rotate the handwheel 401 to drive the screw 4 to rotate. Due to the threaded engagement between the screw 4 and the internal threaded tube 305 and the limiting effect of the rotating seat 202, the initial rotation will cause the can lid 2 to press down until the second connecting ring 201 and the first connecting ring 102 press against the sealing ring 104 to complete the seal. When the handwheel 401 is rotated further, the downward movement of the can lid 2 is blocked, which in turn drives the C-shaped support frame 3 to move upward, so that the rectangular pressing blocks 301 on both sides press tightly against the lower end face of the second connecting ring 201. At the same time, the rectangular limiting block 302 is inserted into the rectangular limiting groove 103 of the first connecting ring 102 to achieve rigid locking. When unlocking, rotating the handwheel 401 in the reverse direction causes the C-shaped support frame 3 to descend to the load-bearing position of the rotating support base 101. After the rectangular limit block 302 disengages from the limit groove, continued rotation raises the can lid 2 as a whole. At this point, pushing the C-shaped support frame 3 to rotate around the fixed shaft 303 easily removes the can lid 2. This structure achieves self-locking through screw drive, and by designing the main load-bearing components on the rotatable C-shaped support frame 3, the operating weight of the can lid 2 is significantly reduced.

[0023] 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.
