Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of dissection table, especially to a hidden cover opening dissection table. BACKGROUND

[0002] The experimental dissection table is a device for storing human specimens for facilitating experiments, and the application file with the publication number CN115245433A discloses a laboratory dissection table capable of automatically opening and closing a cover. The cover plate of the laboratory dissection table mainly comprises a plurality of parallel slats and elastic connecting strips. The elastic connecting strips connect the slats. However, this dissection table still has some technical defects in the process of use: 1. The two ends of the cover plate are exposed, and the elastic connecting strips may slide out due to loosening; 2. The two ends of the slats frequently rub in the guide grooves, which easily causes wear of the slats. The support effect of the guide grooves on the worn slats is not ideal, and due to different degrees of wear, some slats are supported by the guide grooves, while some slats are suspended. The suspended slats are directly supported by the elastic connecting strips, which causes large deformation of the elastic connecting strips and eventually leads to connection failure; 3. The current slats have a relatively large volume after being rolled up, which causes the rolling mechanism and the stretching mechanism at both ends of the dissection table to occupy a certain head space. This prevents students from observing and operating the dissection table at both ends during dissection experiment teaching, thereby affecting dissection experiment teaching. SUMMARY

When the upper cover plate 3 is in the closed state, it is hidden in the side hidden space and the lower hidden space.

[0039] As shown in Figure 1 and Figure 2 , 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 plate 3 is the length direction. Of course, the extension direction of the support guide groove 102 can also be the width direction, and then the sliding direction of the upper cover plate 3 is the width direction, sliding from both sides of the storage box 1 to open or close.

[0040] 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 hides 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.

[0041] In this embodiment, the upper cover plate 3 is driven to slide between the opening and closing stations by an automatic opening and closing power device.

[0043] Wherein, the traction line in the embodiment is a synchronous belt 5, and the wire guide wheel is a synchronous belt guide wheel 6, and meanwhile, the forward and reverse winding device comprises a forward and reverse driving motor 8 which is installed at the bottom of the storage box 1, and the bottom of the storage box 1 is also rotatably installed with a synchronous shaft 9 which is in transmission with the forward and reverse driving motor 8 through a synchronous belt 5 or a chain or the like transmission mechanism. The two ends of the synchronous shaft 9 are fixedly installed with synchronous winding wheels 10, and the synchronous belt 5 in the embodiment is two and is wound on the corresponding synchronous winding wheels 10 respectively, and the synchronous belt 5 is fixed on the two sides of the upper cover plate 3 respectively, so as to drive the upper cover plate 3 to slide.

[0044] And in the embodiment, the side hidden space and the lower hidden space are also provided with guide rails which are in engagement with the support guide grooves 102, and the upper cover plate 3 runs in the support guide grooves 102 and the guide rails. Wherein, since the synchronous belt 5 is adopted as the traction drive in the embodiment, the synchronous belt guide wheels 6 installed in the side hidden space and the lower hidden space can play a certain guiding role, and therefore, the guide rails are discontinuous guide rails which comprise corner guide blocks 7 at the turning positions of the running route of the upper cover plate 3, and the corner guide blocks 7 are provided with guide rail grooves which facilitate the side running of the upper cover plate 3, and the synchronous belt guide wheels 6 are arranged at intervals on the other running tracks as guides.

[0045] As shown in Figure 9 and Figure 10 The upper cover plate 3 in the embodiment comprises a plurality of hard cover plate strips 31 which are connected with each other through flexible connecting strips 32, and the two ends of the cover plate strip 31 are detachably fixed with support end covers 34, the support end covers 34 at the same end of the adjacent cover plate strips 31 cooperatively shield the ends of the connecting strips 32, the bottom of the support end cover 34 is provided with a support portion 344, and the support end cover 34 is supported in the support guide groove 102.

[0046] Wherein, the material of the cover plate strip 31 can be hard plastic or metal, and the connecting strip 32 can be selected from flexible materials such as silica gel.

[0047] Wherein, the support end cover 34 is detachably fixed on the end of the cover plate strip 31 through a fastener 35, the support portion 344 of the support end cover 34 is a wear-resistant support portion 344, and the two ends of the cover plate strip 31 are provided with assembly grooves 312 which extend along the length direction of the cover plate strip 31, and correspondingly, the support end cover 34 is provided with a positioning embedded protrusion 341 which is embedded in the assembly groove 312.

[0048] The bottom of the support end cover 34 is also provided with a wrapping part 343 which extends along the length direction of the cover plate strip 31 and wraps the end of the cover plate strip 31, and the bottom of the wrapping part 343 constitutes the wear-resistant support part 344. The support end cover 34 can be made of wear-resistant materials such as nylon.

[0049] The cover plate strip 31 is a hollow profile, and the inner cavity of the profile is provided with a reinforcing rib 311 which separates the inner cavity of the profile into the assembly groove 312, and the fastener 35 is fixed on the reinforcing rib 311. Each cover plate strip 31 has the same shape and can be molded by a mold. The inner cavity bottom wall of the hollow profile is provided as an arched bottom wall which arches upward.

The cover edge 314 is supported by the support convex rib 313 and is flush with the upper surface of the adjacent cover plate strip 31. Therefore, when the upper cover plate 3 is unfolded and in the closed state, the support convex rib 313 supports the cover edge 314, so that the stress of the cover plate strip 31 is supported by each other and ultimately supported by the support end cover 34, reducing the force acting on the connecting strip 32 and avoiding connection failure.

[0052] The bottom of both sides of the cover plate strip 31 is provided with an avoiding inclined surface 315 which makes the cover plate strip 31 form a structure of narrow bottom and wide top.

The side surface of the cover plate strip 31 at the most edge is fixedly connected with a bumper strip 33.

[0053] Due to the existence of the avoiding inclined surface 315 and the avoiding inclined surface 342, the turning radius is smaller when the upper cover plate 3 slides to the corner of the hidden temporary storage space 4, which reduces the width of the hidden temporary storage space 4 and facilitates the observation or operation of the experiment by the college standing at the end. Embodiment Two

[0054] As shown in the drawings, Figure 3 , Figure 4 and Figure 7As shown, the structure in the embodiment is basically the same as that of embodiment one, and the opening and closing of the upper cover plate 3 is also driven by an automatic opening and closing power device. Only in this embodiment, the traction line is a steel wire rope 13, and the guide wheel is a steel wire rope guide wheel 11, and the forward and reverse winding device includes a forward and reverse drive motor 8, which is installed at the bottom of the storage box 1. Similarly, the bottom of the storage box 1 is also rotatably installed with a synchronous shaft 9, and the synchronous shaft 9 and the forward and reverse drive motor 8 are connected through a synchronous belt 5 or a chain transmission mechanism. The two ends of the synchronous shaft 9 are fixedly installed with a steel wire winding wheel 10-1. In this embodiment, the steel wire rope 13 is two and is wound on the corresponding steel wire winding wheel 10-1. The two ends of the steel wire rope 13 are fixedly installed at the upstream end and the downstream end of the upper cover plate 3 to form a loop, and the traction of the steel wire rope 13 can drive the upper cover plate 3 to slide.

[0055] The guide rail in this embodiment is a continuous rail groove 12, one end of which is connected with the support guide groove 102, and the other end extends to the steel wire winding wheel 10-1, thereby forming the running track of the upper cover plate 3. The continuous rail groove 12 can ensure smooth and reliable operation of the upper cover plate 3.

[0056] Of course, both embodiment one and embodiment two use a forward and reverse drive motor 8 to drive the steel wire winding wheel 10-1 or the synchronous belt 5 winding wheel to reverse to achieve opening or closing, and the winding mechanism and the stretching mechanism in the background art can also be separately controlled to close and open. Embodiment three

[0057] As shown in Figure 5 and Figure 8 In this embodiment, the opening and closing drive of the upper cover plate 3 is simplified to further reduce the cost. In this embodiment, the upper cover plate 3 adopts a manual opening and closing mode. The upper cover plate 3 can also use the guide rail as recorded in embodiment two to facilitate the constraint of the running track of the upper cover plate 3. At the same time, a limiting device is arranged between the upper cover plate 3 and the support guide groove 102 to limit the upper cover plate 3 in the open state.

[0058] As shown in Figure 8 The limiting device includes a limiting shaft 14 fixed on the side surface of the upper cover plate 3. Correspondingly, a limiting baffle 15 is arranged on the support guide groove 102.
