Description

Technical Field

[0001] The invention relates to the technical field of dissecting tables, and in particular to a method for opening and closing a cover of a dissecting table. Background Art

[0002] A dissecting table is a device for storing human specimens for convenient experimental dissection. An invention application document with publication number CN115245433 A discloses a laboratory dissecting table with a cover that can be opened and closed automatically. The cover of the laboratory dissecting table mainly includes a plurality of parallel slats and elastic connecting strips, and the elastic connecting strips connect the slats. However, the opening and closing method of the laboratory dissecting table is achieved by the cooperation of a winding mechanism and a stretching mechanism installed at both ends of the dissecting table. The specific opening and closing method is to use the winding mechanism to roll up the cover while the stretching mechanism is extended to open the cover; then when the stretching mechanism is contracted, the winding mechanism is unwound to close the cover. However, there are still some technical problems in opening and closing the cover of this dissecting table: first, the slats of this opening and closing method will be relatively large after being rolled up, resulting in the rolling mechanism and stretching mechanism at both ends of the dissecting table needing to occupy a certain amount of head space. This results in that during the anatomical experiment teaching, the students cannot observe and operate at both ends of the dissecting table, thus affecting the anatomical experiment teaching; secondly, the two ends of the cover are exposed, and the elastic connecting strip may slip out due to looseness. The two ends of the slats frequently rub in the guide groove, which can easily cause wear of the slats, and the support effect of the worn slats by the guide groove is not ideal, and due to different degrees of wear, some slats will be supported by the guide groove, while some slats will be suspended. The suspended slats will be directly supported by the elastic connecting strip, resulting in large pulling deformation of the elastic connecting strip, and eventually the connection failure will easily occur. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a method for opening and closing the cover of a dissecting table, which can hide the upper cover when opening the cover, thereby reducing the space at the end of the dissecting table and making it convenient for trainees to observe and teach at the end of the dissecting table.

[0004] In order to solve the above technical problems, the technical solution of the present invention is: a method for opening and closing the cover of a dissecting table, the dissecting table comprises a storage box and a rollable upper cover plate, the upper end of the storage box is open, the side wall of the upper end of the storage box is provided with a support guide groove, the outer side of the storage box is provided with an outer shell, and a hidden temporary storage space is provided between the outer shell and the storage box;

[0005] When the upper cover needs to be opened, the upper cover is pushed or pulled to slide into the hidden temporary storage space, and the upper cover gradually turns from the support guide groove into the hidden temporary storage space until the upper end opening of the upper cover is fully opened, and the upper cover remains in the open state;

[0006] When the upper cover needs to be closed, the upper cover is pulled or pushed in the opposite direction, and the upper cover turns from the hidden temporary storage space and gradually slides into the support guide groove until the upper cover closes the upper opening, at which time the upper cover remains in a closed state.

[0007] Preferably, the sliding of the upper cover plate is driven by an automatic opening and closing power device to automatically open or close, or the upper cover plate is manually pushed to slide to achieve manual opening or closing. The sliding of the upper cover plate can be opened or closed manually or automatically to meet different needs of different costs.

[0008] Preferably, the automatic opening and closing power device includes a forward and reverse driving motor and a traction line, and both ends of the upper cover are respectively fixed to the traction line. The forward and reverse driving motor drives the traction line to run forward and reverse to pull the upper cover forward and reverse, and the forward and reverse operation of the traction line is utilized to pull the upper cover forward and reverse to achieve opening or closing.

[0009] Preferably, the automatic opening and closing power device includes an elastic rope reel and a forward and reverse drive motor, the forward and reverse drive motor is connected to one end of the upper cover plate through a traction rope, and the traction rope wound by the elastic rope reel is connected to the other end of the upper cover plate.

[0010] Preferably, the hidden temporary storage space includes a side hidden space arranged on the side of the storage box and a lower hidden space arranged at the bottom of the storage box, and the upper cover plate slides into the side hidden space and the lower hidden space along the length direction or the width direction of the storage box, so that the hidden temporary storage space can accommodate a longer upper cover plate, better ensuring that the upper cover plate can slide smoothly, and the upper cover plate can enter the hidden temporary storage space along the length direction or the width direction, which is more flexible.

[0011] Preferably, guide rails connected with the supporting guide grooves are arranged in the side hidden space and the lower hidden space, and the upper cover is constrained and guided by the guide rails when sliding into the side hidden space. The guide rails can facilitate the smooth sliding of the upper cover and better constrain the running trajectory of the upper cover.

[0012] Preferably, the guide rail is a continuous guide rail or a segmented guide rail. When the segmented guide rail is used, the guide rail is arranged at the turning point of the upper cover plate. The use of the segmented guide rail can save costs while ensuring smooth sliding at the critical part of the turning.

[0013] Preferably, the upper cover is maintained in an open state in the following manner: a limit baffle is provided in the support guide groove, and a limit shaft cooperating with the limit baffle is provided at the end of the upper cover; when the limit shaft collides with the limit baffle, the upper cover can be limited to be in an open state; the cooperation of the limit shaft and the limit baffle can prevent the end of the upper cover from entering the hidden temporary storage space, which also makes it convenient for the upper cover to slide out smoothly when closing.

[0014] Preferably, the upper cover plate comprises a plurality of hard cover strips, adjacent cover strips are connected to each other by flexible connecting strips, and support end caps are detachably fixed to the two ends of each cover strip, and the support end caps at the same end of adjacent cover strips cooperate with each other to cover the ends of the connecting strips, and a wear-resistant support portion is provided at the bottom of the support end cap, and the support end cap is located in the support guide groove and the support portion is supported and slidably cooperated in the support guide groove. The upper cover plate has a reasonable structure, and the support end cap can seal the connecting strip to prevent the connecting strip from slipping out. At the same time, the wear-resistant support portion at the bottom of the support end cap slides directly with the support guide groove, thereby improving wear resistance and being very convenient to replace.

[0015] Preferably, after the upper cover is opened, a side edge of the cover strip in the length direction is overlapped and supported on the side edge of another adjacent cover strip, so that the force on the opened upper cover is more reasonable, and the entire supporting force can be supported by the mutual cover strips. The bearing capacity of the entire upper cover is greater, and some other items can be placed on the upper cover after closing. At the same time, the opened upper cover will not squeeze the connecting strip, thereby avoiding deformation of the connecting strip and causing connection failure.

[0016] After adopting the above technical scheme, the effect of the present invention is: when the opening and closing method opens the upper cover plate that can be rolled and bent, the upper cover plate will also be moved from the support guide groove of the upper end opening into the hidden temporary storage space. Since the upper cover plate is a plate-like structure, the width of the hidden temporary storage space does not need to be too wide to meet the entry of the upper cover plate. Compared with the current winding and reeling method, the space at the end of the dissecting table is greatly reduced, so that the dissecting table can be observed and taught or operated all around, which is convenient for students to use.

[0030] The present invention is further described in detail below through specific examples.

[0031] The present embodiment discloses a method for opening and closing a cover of a dissecting table, which includes a storage box 1 and a rollable and bendable upper cover plate 3. The storage box 1 is used to store human specimens to facilitate experimental teaching. The upper end of the storage box 1 is opened 101, and the side wall of the upper end opening 101 of the storage box 1 is provided with a supporting guide groove 102. The outer side of the storage box 1 is provided with an outer shell 2, and a hidden temporary storage space 4 is provided between the outer shell 2 and the storage box 1.

[0032] When it is necessary to open the upper cover 3, push or pull the upper cover 3 to slide into the hidden temporary storage space 4, and the upper cover 3 gradually turns from the support guide groove 102 to enter the hidden temporary storage space 4 until the upper cover 3 fully opens the upper end opening 101. At this time, the upper cover 3 remains in the open state, wherein when the upper cover 3 is in the open state, the end of the upper cover 3 is just at the end of the upper end opening 101, that is, a part of the end of the upper cover 3 is just located in the support guide groove 102 and has not fully entered the hidden temporary storage space 4, so that the upper end opening 101 can be better pulled to close the cover when closing the cover.

[0033] When the upper cover 3 needs to be closed, the upper cover 3 is pulled or pushed in the opposite direction, and the upper cover 3 turns from the hidden temporary storage space 4 and gradually slides into the support guide groove 102 until the upper cover 3 closes the upper end opening 101, and the upper cover 3 remains in the closed state.

[0034] The upper cover 3 can be opened or closed manually or automatically by the automatic opening and closing power device, or can be opened or closed manually by manually pushing the upper cover 3 to slide. The upper cover 3 can be opened or closed manually or automatically to meet different needs of different costs.

[0035] The automatic opening and closing power device includes a forward and reverse driving motor 8 and a traction line. The two ends of the upper cover plate 3 are respectively fixed to the traction line. The forward and reverse driving motor 8 drives the traction line to run forward and reverse to pull the upper cover plate 3 to run forward and reverse to achieve opening or closing.

[0036] The upper cover plate 3 includes a plurality of hard cover plate strips 31, and adjacent cover plate strips 31 are connected to each other by flexible connecting strips 32. The two ends of each cover plate strip 31 are detachably fixed with support end covers 34. The support end covers 34 at the same end of adjacent cover plate strips 31 cooperate with each other to cover the ends of the connecting strips 32. The bottom of the support end cover 34 is provided with a wear-resistant support portion 344, and the support end cover 34 is located in the support guide groove 102 and the support portion 344 is supported in the support guide groove 102 for sliding cooperation. The upper cover plate 3 has a reasonable structure, and the support end cover 34 can cover the connecting strip 32 to prevent the connecting strip from sliding out. At the same time, the wear-resistant support portion 344 at the bottom of the support end cover 34 directly slides with the support guide groove 102, which improves wear resistance and is also very convenient for replacement.

[0037] Preferably, after the upper cover 3 is opened, a side edge of the cover strip 31 in the length direction overlaps and supports the side edge of another adjacent cover strip 31, forming a male-female positioning support structure. In this way, the force of the opened upper cover 3 is more reasonable, and the entire support force can be supported by the mutual cover strips 31, and the bearing capacity of the entire upper cover 3 is greater. After closing, some other items can be placed on the upper cover 3. At the same time, the opened upper cover 3 will not squeeze the connecting strip 32, avoiding deformation of the connecting strip 32 and causing connection failure.

[0038] In this regard, this specific embodiment illustrates three specific embodiments of the above-mentioned method of opening and closing the cover.

[0039] Embodiment 1

[0040] like Figure 1 , Figure 2 and Figure 7 As shown, a hidden open-cover dissection table comprises a storage box 1 and a rollable upper cover plate 3. The basic structure of the dissection table is similar to the structure of the laboratory dissection table disclosed in the invention application document CN115245433 A.

[0041] In this embodiment, the upper end opening 101 of the storage box 1 has support guide grooves 102 on its side walls, which can facilitate the sliding of the upper cover plate 3 and support the two side edges of the upper cover plate 3.

[0042] An outer shell 2 is arranged on the outside of the storage box 1, and a hidden temporary storage space 4 is arranged between the outer shell 2 and the storage box 1. In this embodiment, the storage box 1 is a rectangular structure, and the hidden temporary storage space 4 includes a side hidden space located on the side of the storage box 1 and a lower hidden space located at the bottom of the storage box 1. When in a closed state, the upper cover plate 3 is in the side hidden space and the lower hidden space.

[0043] like Figure 1 and Figure 2 In the figure, the extension direction of the support guide groove 102 is the length direction of the storage box 1, so the sliding direction of the upper cover 3 is the length direction. Of course, the extension direction of the support guide groove 102 can also be the width direction, then the sliding direction of the upper cover 3 is the width direction, and the storage box 1 is opened or closed by sliding from both sides.

[0044] The upper cover plate 3 slides in the support guide groove 102 and the hidden temporary storage space 4. When the upper cover plate 3 is in the open state, the upper cover plate 3 slides and is hidden in the hidden temporary storage space 4; when the upper cover plate 3 is in the closed state, the upper cover plate 3 slides from the hidden temporary storage space 4 to the support guide groove 102 to cover the upper end opening 101.

[0045] In this embodiment, the upper cover plate 3 is driven by an automatic opening and closing power device to slide between the opening and closing positions. The opening and closing of the upper cover plate 3 is driven by the automatic opening and closing power device, thereby realizing automatic opening and closing of the cover.

[0046] Figure 1 The middle is a schematic diagram when the upper cover 3 is closed. Figure 2 FIG. 3 is a schematic diagram showing the upper cover plate 3 in an open state. Figure 2 and Figure 7 As shown, the automatic opening and closing power device includes a traction line, and the traction line is driven by a forward and reverse winding device to be pulled forward and backward. The upper cover plate 3 is fixed to the traction line and moves with the traction line. A wire wheel is arranged in the hidden space to facilitate the traction operation of the traction line.

[0047] Among them, the traction line in this embodiment is a synchronous belt 5, and the guide wheel is a synchronous belt guide wheel 6, and the forward and reverse winding device includes a forward and reverse driving motor 8, which is installed below the storage box 1. Similarly, a synchronous shaft 9 is also rotatably installed below the storage box 1, and the synchronous shaft 9 and the forward and reverse driving motor 8 are driven by a transmission mechanism such as a synchronous belt 5 or a chain. Synchronous winding wheels 10 are fixedly installed at both ends of the synchronous shaft 9. There are two synchronous belts 5 in this embodiment and they are respectively wound on the corresponding synchronous winding wheels 10. The synchronous belts 5 are respectively fixed to the two sides of the upper cover plate 3, so that the upper cover plate 3 can be driven to slide.

[0048] In this embodiment, the side hidden space and the lower hidden space are further provided with guide rails that engage with the support guide groove 102, and the upper cover plate 3 runs in the support guide groove 102 and the guide rails. In this embodiment, since the synchronous belt 5 is used as the traction drive, the synchronous belt guide wheel 6 installed in the side hidden space and the lower hidden space can play a certain guiding role. Therefore, the guide rail is a discontinuous guide rail, which mainly supports the turning point of the upper cover plate running route, such as Figure 7 As shown, it includes a corner guide block 7 at the turning point of the upper cover plate 3 running route, and the corner guide block 7 is provided with a guide track groove for facilitating the side running of the upper cover plate 3, while synchronous belt guide wheels 6 are arranged at intervals on other running tracks for guidance.

[0049] like Fig.10 and Fig.11 As shown, the upper cover plate 3 in this embodiment includes a plurality of hard cover plate strips 31, and adjacent cover plate strips 31 are interconnected by flexible connecting strips 32. Support end caps 34 are detachably fixed at the two ends of the cover plate strips 31. The support end caps 34 at the same end of adjacent cover plate strips 31 cooperate with each other to cover the ends of the connecting strips 32. A support portion 344 is provided at the bottom of the support end cap 34, and the support end cap 34 is supported in the support guide groove 102.

[0050] The cover strip 31 may be made of hard plastic or metal, while the connection strip 32 may be made of flexible material, such as silicone.

[0051] Among them, the support end cover 34 is detachably fixed to the end of the cover strip 31 by a fastener 35, and the support portion 344 of the support end cover 34 is a wear-resistant support portion 344. Both ends of the cover strip 31 are provided with assembly grooves 312 extending along the length direction of the cover strip 31, and correspondingly, the support end cover 34 is provided with a positioning embedding protrusion 341 embedded in the assembly groove 312.

[0052] In this embodiment, a wrapping portion 343 is further provided at the bottom of the support end cap 34, and the wrapping portion 343 extends in the length direction of the cover strip 31 and wraps the end of the cover strip 31, and the bottom of the wrapping portion 343 constitutes the wear-resistant support portion 344. The support end cap 34 can be made of wear-resistant materials such as nylon.

[0053] The cover strip 31 is a hollow profile, and the inner cavity of the profile is provided with a reinforcing rib 311, and the reinforcing rib 311 divides the inner cavity of the profile into the assembly groove 312. The fastener 35 is fixed on the reinforcing rib 311. Each cover strip 31 has the same shape, so it can be formed by a mold. The inner cavity bottom wall of the hollow profile is set as an arched bottom wall that arches upward, and the arched bottom wall can improve the strength of the hollow profile and improve the load-bearing capacity.

[0054] Both side edges of the cover strip 31 are provided with strip-shaped embedding grooves 316 extending along the length direction, and both side edges of the connecting strip 32 are provided with strip-shaped embedding blocks 321 embedded in the strip-shaped embedding grooves 316. Male-female positioning support structures are also provided between adjacent cover strips 31 to form overlapping supports.

[0055] like Fig.10 As shown, the positioning support structure includes a supporting convex rib 313 arranged on one side of the cover strip 31, and correspondingly, the side of the cover strip 31 on the adjacent side is covered with a cover edge 314 on the supporting convex rib 313, and the cover edge 314 is supported by the supporting convex rib 313 so that the upper surface of the adjacent cover strip 31 is flush. Therefore, when the upper cover 3 is unfolded and in a closed state, the supporting convex rib 313 will support the cover edge 314, so that the forces on the cover strip 31 will support each other and finally be supported by the supporting end cap 34, reducing the force on the connecting strip 32 and avoiding deformation of the connecting strip 32 and connection failure.

[0056] The bottom of both sides of the cover strip 31 is provided with avoidance inclined surfaces 315, which make the cover strip 31 form a structure that is narrow at the bottom and wide at the top. Both sides of the support end cover 34 are also provided with avoidance inclined surfaces 342, which make the support end cover 34 form a structure that is narrow at the bottom and wide at the top. The side of the cover strip 31 at the edge is fixedly connected with an anti-collision strip 33.

[0057] Due to the existence of the avoidance inclined surface 315 and the avoidance inclined surface 342, the turning radius of the upper cover plate 3 is smaller when it slides to the corner of the hidden temporary storage space 4, thereby reducing the width of the hidden temporary storage space 4 and making it convenient for trainees to stand at the end to observe or operate the experiment.

[0058] Embodiment 2

[0059] like Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the structure in this embodiment is basically the same as that in the first embodiment, and the opening and closing of the upper cover plate 3 is also driven by an automatic opening and closing power device. However, in this embodiment, the traction line is replaced by a wire rope 13, and the guide wheel is a wire rope guide wheel 11, and the forward and reverse winding device includes a forward and reverse driving motor 8, which is installed below the storage box 1 and located in the lower hidden space. Similarly, a synchronous shaft 9 is also rotatably installed below the storage box 1, and the synchronous shaft 9 and the forward and reverse driving motor 8 are driven by a transmission mechanism such as a synchronous belt 5 or a chain. The two ends of the synchronous shaft 9 are fixedly installed with a wire winding wheel 10-1. In this embodiment, there are two wire ropes 13 and they are respectively wound on the corresponding wire winding wheels 10-1. The two ends of the wire rope 13 are respectively fixed on the upstream end and the downstream end of the upper cover plate 3 to form a closed loop. The forward and reverse traction of the wire rope 13 can drive the upper cover plate 3 to slide forward and backward.

[0060] The guide track in this embodiment is a continuous track groove 12, one end of which is connected to the support guide groove 102, and the other end extends to the wire winding wheel 10-1, thereby forming a running track of the upper cover plate 3. The continuous track groove 12 can ensure that the upper cover plate 3 runs smoothly and reliably.

[0061] Of course, in both the first and second embodiments, a forward and reverse driving motor 8 is used to drive the wire winding wheel 10-1 or the synchronous belt 5 winding wheel to rotate forward and reverse to realize opening or closing. The winding mechanism and the stretching mechanism in the background technology can also be used to separately control closing and opening. For example, the automatic opening and closing power device may include an elastic rope reel and a forward and reverse driving motor, the forward and reverse driving motor is connected to one end of the upper cover plate through a traction rope, and the traction rope wound by the elastic rope reel is connected to the other end of the upper cover plate.

[0062] Embodiment 3

[0063] like Figure 6 and Fig. 9 As shown, in this embodiment, the opening and closing drive of the upper cover 3 is simplified to further reduce the cost. The upper cover 3 in this embodiment adopts a manual opening and closing method, wherein the upper cover 3 can also adopt the guide track recorded in the second embodiment to facilitate the constraint of the running trajectory of the upper cover 3. At the same time, a limit device for limiting the upper cover 3 to be in an open state is also provided between the upper cover 3 and the supporting guide groove 102.

[0064] like Figure 8 As shown, the limiting device includes a limiting shaft 14 fixed to the side of the upper cover plate 3, and correspondingly, a limiting baffle 15 is arranged on the support guide groove 102. When the limiting shaft 14 relies on the limiting baffle 15, the upper cover plate 3 will no longer slide, and the upper cover plate 3 is limited to the open position at this time. When closing, it only needs to manually pull or push the upper cover plate 3 so that the upper cover plate 3 slides in the support guide groove 102 to close, and the overall length of the upper cover plate 3 can be set to be relatively long, so as to ensure that the upper cover plate 3 completely covers the upper end opening 101. Of course, the limiting shaft 14 can also be arranged at the other end of the upper cover plate 3, so when closing, the limiting shaft 14 at the other end of the upper cover plate 3 collides with the limiting baffle 15, so that it can be prevented from sliding over the position when the upper cover plate is manually slid.

[0065] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the scope of protection defined by the claims of the present invention.
