Description

TECHNICAL FIELD

[0001] The present application relates to a kind of non-contact medical waste collection container. BACKGROUND

[0002] At present, in non-contact medical waste collection container, unilateral opening garbage bag is often used, such as patent literature with announcement number CN210028481U.

[0003] In order to realize automatic opening of garbage bag, some use clamps to hold and pull garbage bag to open garbage bag, such as patent literature with announcement number CN216036547U. The purpose of clamps holding garbage bag is to pull the outer layer of garbage bag (the layer without easy-to-tear line, hereinafter referred to as outer layer) outward, because the other side (the layer with easy-to-tear line, hereinafter referred to as inner layer) is provided with easy-to-tear line and will not move, so as to open the garbage bag.

[0004] Because the wall thickness of garbage bag is very thin, but the situation of "clamps holding two layers of garbage bag" often occurs, and the garbage bag cannot be truly opened. SUMMARY

[0005] The technical problem to be solved by the present application is how to design a non-contact medical waste collection container (also known as medical garbage can) to facilitate automatic opening of garbage bag.

[0006] The technical solution of the present application is as follows:

[0007] A non-contact medical waste collection container includes a box body with a hinged cover and a dispensing window on the cover. Two tracks are fixed to the box body, and a support member is installed inside the box body, capable of sliding along the two tracks. The support member includes a connecting frame with a slider that slides along it. The sliding direction of the slider is the same as the sliding direction of the support member. An assembly chamber is provided on the vertical plate of the connecting frame, and a clamp is provided inside the assembly chamber. The end of the clamp's pin is fixed to the slider. The assembly chamber includes a front end and a rear end, with the height of the front end greater than the height of the rear end. When the clamp's tail is inside the rear end of the chamber, it is constrained by the upper and lower walls of the rear end and cannot clamp tightly. When the clamp's tail is inside the front end of the chamber, it can clamp tightly. A torsion spring is sleeved on the clamp's pin, and the two torsion bars of the torsion spring are respectively fixed to the two clamp plates of the clamp. When there is no external force on the clamp, the two clamp tails of the clamp are clamped together; a compression spring is provided between the connecting frame and the slider; the connecting frame fixes the connecting plate, and the upper surface of the connecting plate fixes the fixed end of the control pin, the free end of the control pin bends upward to form a vertical part; the lower surface of the slider is provided with a mating cavity, the vertical part of the control pin is located in the mating cavity, the mating cavity includes a front annular cavity and a rear strip cavity, the annular cavity is provided with a lake island block, the lake island block is fixed on the slider; the front side of the lake island block is provided with a V-shaped recess; a ramp is fixed in the annular cavity, the annular cavity on one side of the ramp is the high zone, the annular cavity on the other side of the ramp is the low zone, the low zone is connected to the strip cavity, the front side of the annular cavity is provided with a V-shaped protrusion, the V-shaped protrusion is located in the high zone area; the box body is provided with a boss at the position where the garbage bag hangs down; a front plate is fixed on the slider, the front side of the front plate is provided with a notch that mates with the boss.

[0008] The fixed end of the control needle is ring-shaped.

[0009] Both the working surface of the clamp and the outer surface of the boss are friction surfaces.

[0010] Compared with the prior art, the technical effect of the present invention is that the present invention is provided with a boss. When the clamp holds the garbage bag on the boss and pulls it backward, the outer side of the garbage bag moves backward, while the inner layer of the garbage bag does not move, thus realizing the automatic opening of the garbage bag.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0029] In this instruction manual, the direction closest to the garbage bag is front, and the opposite direction is back.

[0030] like Figure 1 A non-contact medical waste collection container includes a box body 100, a cover 110 hinged to the box body 100, and a dispensing window 180 on the cover 110.

[0031] like Figure 2Two rails 120 are fixed on the housing 100, and a support member 200 is provided inside the housing 100. The support member 200 can slide along the two rails 120. In order to realize the sliding of the support member 200, this application provides a power part to drive the sliding of the support member 200. Since it is prior art, it will not be described in detail.

[0032] like Figures 3-6 The support member 200 includes a connecting frame 201, on which a slider 580 is provided that can slide. The sliding direction of the slider 580 is the same as the sliding direction of the support member 200. The vertical plate 580 of the connecting frame 201 is provided with an assembly chamber. A clamp 500 is provided in the assembly chamber. The end of the pin 554 of the clamp 500 is fixed to the slider 580. The assembly chamber includes a front end 212 and a rear end 211. The height of the front end 212 is greater than the height of the rear end 211. When the clamp tail 501 of the clamp 500 is located in the rear end 211 of the chamber (that is... Figure 6 When the clamp 500 is in an open state, it is constrained by the upper and lower chamber walls of the rear end 211 of the chamber; when the clamp tail 501 of the clamp 500 is located in the front end 212 of the chamber, the clamp 500 clamps.

[0033] like Figure 6 A torsion spring 555 is fitted around the pin 554 of clip 500. The two torsion bars of the torsion spring 555 are fixed to the two clamping plates of the clip respectively. In the initial position of the clip, the empty pointer is in the position shown below. Figure 11 When the clip 500 is in the open state, the two clip tails 501 of the clip 500 are clamped together; conversely, when the bent needle of 232 is at the end of 320, 580 is in the spring-extended outward state, and the clip is in the clamped state.

[0034] like Figure 4 A compression spring 510 is provided between the connecting frame 201 and the slider 580. The compression spring 510 keeps the two as far apart as possible, reaching the limit position of the control pin 231.

[0035] like Figures 7-10 The connecting bracket 201 fixes the connecting plate 230. The upper surface of the connecting plate 230 fixes the fixed end of the control pin 231. The free end of the control pin 231 (the opposite end of the fixed end) bends upward to form a vertical part 233.

[0036] like Figures 10-12 The lower surface of the slider 580 is provided with a mating cavity 300. The vertical part 233 of the control needle 231 is located in the mating cavity 300. The mating cavity 300 includes a front annular cavity 310 and a rear strip cavity 320. A lake island block 330 is provided in the annular cavity 310. The lake island block 330 is fixed on the slider 580. The annular cavity 310 around the lake island block 330 is the movement path of the vertical part 233.

[0037] like Figure 11 The front side of the island block 330 in the lake center is provided with a V-shaped recess 331.

[0038] like Figure 11 An annular cavity 310 has a fixed ramp 340. The annular cavity 310 on one side of the ramp 340 is a high zone 311, and the annular cavity 310 on the other side of the ramp 340 is a low zone 312. The low zone 312 is connected to the strip cavity 320. The front side of the annular cavity 310 is provided with a V-shaped protrusion 313, which is located in the area of ​​the high zone 311.

[0039] The term "high zone" means that the bottom of the annular cavity 310 (the upper surface of the annular cavity) is located at a higher position; the term "low zone" means that the bottom of the annular cavity 310 (the upper surface of the annular cavity) is located at a lower position.

[0040] like Figures 13-15 The container 100 has a protrusion 130 at the position where the garbage bag hangs down.

[0041] like Figures 12-15 A front plate 400 is fixed on the slider 580, and the front side of the front plate 400 is provided with a notch 410 that mates with the boss 130.

[0042] like Figure 11 To facilitate fixing the fixed end of the control pin 231, the fixed end of the control pin 231 is a ring 232.

[0043] For ease of clamping, both the working surface of the clamp 500 and the outer surface of the boss 130 are friction surfaces (not shown in the figure) to increase the maximum static friction between them and the garbage bag 900.

[0044] This application has two core aspects:

[0045] S1, such as Figure 16 With the protrusion 130 in place, when the clamp 500 holds the garbage bag 900, the protrusion 130 has entered the notch 410 of the front plate 400. The front plate 400 presses the garbage bag 900 into a "U" shape. The garbage bag 900 covers the upper, rear, and lower surfaces of the protrusion 130. When the clamp 500 clamps the outer layer 902 of the garbage bag 900, the maximum static friction between the clamp 500 and the outer layer 902 of the garbage bag 900, and the maximum static friction between the inner layer 901 of the garbage bag 900 and the protrusion 130 are both greater than the maximum static friction between the outer layer 902 and the inner layer 901 of the bag 900 and the protrusion. Therefore, when the clamp 500 moves backward with the outer layer 902 in place, the inner layer 901 of the garbage bag 900 remains in place, and the garbage bag 900 is stretched open.

[0046] S2. By controlling the different positions of the vertical portion 233 of the control pin 231 within the mating cavity 300, a short-range movement space for the slider 580 relative to the connecting frame 201 is created to achieve the switching of the "tail 501 of the clip 500 being located within the rear end 211 of the chamber and within the front end 212 of the chamber", thus completing the switching between the two states of the clip 500 being clamped and released.

[0047] S3. By controlling the different positions of the vertical portion 233 of the control pin 231 within the mating cavity 300, when the撑开 member 200 slides backward, the compression spring 510 can also be switched between the "姿态 of being compressed to the shortest length" and the "reset姿态": when the撑开 member 200 pulls the garbage bag back on the return journey, the compression spring 510 maintains the "姿态 of being compressed to the shortest length" to ensure that the clip clamps the garbage bag; when the garbage is taken away after packing and the撑开 member 200 pulls the garbage bag back on the return journey, the compression spring 510 maintains the "reset姿态" to ensure that the clip is in the open state, preparing for clamping the garbage bag next time.

[0048] Its working principle is as follows:

[0049] S1. Initial state: Due to the action of the compression spring 510, the vertical portion 233 of the control pin 231 is located within the strip cavity 320;

[0050] S2. The撑开 member 200 (together with the clip 500, the slider 580, and the protruding front plate 400) moves from the rear end ( Figure 5 the right side direction) towards the garbage bag 900 direction (which is forward);

[0051] S3. As Figure 14 , when the notch 410 reaches the position of the boss 130, the protruding front plate 400 presses the garbage bag 900 into a "几" shape, causing the garbage bag 900 to wrap around the upper surface, rear surface, and lower surface of the boss 130 and other three sides;

[0052] S4. The撑开 member 200 continues to move forward. Since the protruding front plate 400 is blocked by the boss 130 and cannot move forward, the slider 580 and the clip 500 fixed to the protruding front plate 400 are also simultaneously blocked and cannot move. The two clamping plates of the clip 500 are respectively located on the upper and lower sides of the boss 130;

[0053] S5. The撑开 member 200 continues to move. At this time, the control pin 231 fixed to the撑开 member 200 also continues to move forward, and its vertical portion 233 then moves within the mating cavity 300. Specifically: the vertical portion 233 gradually reaches the closest point of the high zone 311 (see the reference numeral 316) from the strip cavity 320 (along Figure 11 the part on the right side of the central island block 330 in ). At this time, the撑开 member 200 moves forward to the limit position, the tail 501 of the clip 500 is located within the front end 212 of the chamber, and the clip clamps the outer layer 902 of the garbage bag 900. It should be noted that the Chinese character "几" in the original text is directly retained in the translation as it may be a specific shape description in the original content. If there is a more specific English equivalent for this shape, it can be further adjusted according to the actual situation. Also, the term "撑开件" is directly translated as "撑开 member" as there is no specific English term provided in the context. It may need to be further defined or adjusted based on the overall technical content.

[0054] Thus, a relative displacement between the slider 580 and the expander 200 is caused, which is equivalent to the slider 580 sliding backward (away from the garbage bag), and the compression spring 510 is also compressed to the shortest length, and the clip 500 is free from the constraint of the assembly chamber, and its two clip tails 501 are clamped on the boss 130, clamping the outer layer 902 of the bag, as shown in Fig. 6B. Figure 16 ;

[0055] S6, the expander 200 starts to move backward, and the protruding plate 400 gradually escapes from the constraint of the boss 130, and at the same time, due to the action of the compression spring 510, the vertical part 233 of the control needle 231 cannot return to the area of the strip-shaped cavity 320 from the nearest point (see reference numeral 316) of the high area 311 to the V-shaped recess 331 of the island block 330, and the compression spring 510 remains in the state of being compressed to the shortest length under the control of the control needle 231, and cannot be reset, and the slider 580, the clip 500, and the outer layer 902 of the bag return together with the expander 200, and the clip is in a clamping state at this time; relative to the S1 step, the slider 580 is located at the protruding position, and the clip tail 501 of the clip 500 continues to be located in the chamber front end 212, and the clip continues to tighten the outer layer 902 of the garbage bag 900.

[0056] S7, when the expander 200, the slider 580, the clip 500, and the outer layer 902 of the bag move to the limit position, the automatic expansion of the garbage bag 900 is realized, and at this time, garbage can be put in;

[0057] S8, after the garbage is put in, the expander 200 moves forward, see S2 step, except that the vertical part 233 of the control needle 231 is still at the V-shaped recess 331 of the island block 330.

[0058] S9, the expander 200 continues to move forward, and at the same time, the expander 200 and the clip 500 continue to move, and at this time, the control needle 231 fixed with the expander 200 also continues to move forward, and its vertical part 233 moves in the matching cavity 300, specifically: the vertical part 233 is forced to pass over the slope 340 from the V-shaped recess 331 and gradually reaches the nearest point (see reference numeral 315) of the low area 312, at this time, the expander 200 moves to the limit position, the clip tail 501 of the clip 500 is located in the chamber front end 212, and the clip keeps tightening the outer layer 902 of the garbage bag 900.

[0059] S10, the opening of the clip: 400 block slider 580 movement, 200 continue to move forward, the control needle 320 from 233 to 315, in 200 return from 315 to 312 to move to the low end of the control needle 320, the clip tail 501 movement to the chamber rear end 211, at this time the clip is open, the clip no longer clamps the outer layer 902 of the garbage bag 900;

[0060] S11, at this time the clip no longer clamps the outer layer 902 of the garbage bag 900, the garbage bag can be sealed, cut and other work, when the support 200 resets to the rear, the garbage bag is released and falls to the bottom of the box 100.

[0061] S12, the support 200 moves to the limit position, preparing for the next opening.

[0062] In view of the step S11 for sealing, cutting and other work of the garbage bag, which is the prior art, the present application will not be described.

[0063] Thus, a cycle is completed.

[0064] Other contents refer to the prior art.

[0065] The above is only the preferred embodiment of the present application, it should be pointed out that for those skilled in the art, without departing from the overall concept of the present application, can also make several changes and improvements, these should be considered as the protection scope of the present application.
