Description

Technical Field

[0001] The present invention relates to the technical field of plastic plates, and in particular to a plastic plate that is easy to connect. Background Art

[0002] Plastic sheets, that is, sheets made of plastic materials, can be roughly divided into hard PVC building sheets, polypropylene plastic sheets (PP plastic sheets), polyethylene plastic sheets (PE plastic sheets) and ABS plastic sheets according to the material. Among them, PP plastic sheets have good surface stiffness and scratch resistance, and they do not have the problem of environmental stress cracking. The grid floor made from them is used in places with large drainage volume, such as chemical industry, aquaculture, car washes, etc., and can take into account the characteristics of pressure resistance and smooth drainage.

[0003] The grille floors in the prior art are generally spliced together by clips and slots at the edges of the grille bottom plate. During assembly, multiple clips and slots need to be precisely docked together. When the grille plate is used in car washes and aquaculture, it is convenient for water to be discharged. However, the space at the bottom of the grille plate is not large, and larger dirt will still be stuck at the bottom of the grille plate. In other words, dirt is easily accumulated at the bottom of the grille plate, and a large amount of clean water is required to rinse it during cleaning, which makes cleaning inconvenient and causes waste of water resources. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems in the background technology and to provide a plastic sheet material that is easy to connect.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

The bottom of the outer sleeve is movably connected to the ejection structure, and a locking structure that limits the ejection structure is installed on the outside of the ejection structure. The pressure column will activate the trigger structure after rapid downward pressure, and the trigger structure controls the locking structure to release the restriction on the ejection structure, so that the ejection structure extends to support the entire outer sleeve.

[0007] In the above-mentioned plastic sheet material that is easy to connect, the trigger structure includes a counterweight plate and a vertically arranged rack, the upper end of the rack is fixedly connected to the lower end of the pressure column, the counterweight plate is rotatably connected to the inside of the outer sleeve, and a ratchet structure is fixedly connected to the shaft rod of the outer sleeve. The outer wall of the ratchet structure is engaged with the outer wall of the rack. When the rack moves downward, it will drive the ratchet structure as a whole to rotate. When the rack moves upward, the outer ring of the ratchet structure will rotate accordingly, and the inner ring of the ratchet structure will not rotate. A deep groove is provided on the outer wall of the counterweight plate, and a traction rope is fixedly connected to the outer wall of the deep groove.

[0008] In the above-mentioned plastic sheet that is easy to connect, the ejection structure includes an extension column, the top of the extension column is fixedly connected to a limiting ring with a diameter larger than the extension column, the top of the extension column is fixedly connected to a strong spring, the upper end of the strong spring is fixedly connected to the baffle, the bottom of the inner wall of the outer sleeve is fixedly connected to the lower sleeve, and the inner side of the lower sleeve is provided with a movable groove for limiting the clamping ring.

[0009] In the above-mentioned plastic sheet material that is easy to connect, a groove is provided at the top of the inner side of the lower sleeve, and the locking structure is installed inside the groove. The locking structure includes an elastic strip, and the upper end of the elastic strip is fixedly connected to the top of the inner wall of the groove. The outer wall of the elastic strip close to the extension column is fixedly connected with a buckle. When the extension column is pressed and moved to the inside of the outer sleeve, the buckle limits the snap ring. An oblique groove is provided on the outer side of the buckle, and the lower end of the elastic strip is fixedly connected to the extension strip.

[0010] In the above-mentioned plastic sheet material that is easy to connect, a slide is provided on the side of the extension strip close to the extension column, and a triangular block that is narrow at the top and wide at the bottom is fixedly connected to the outer wall of the slide on the side close to the extension strip, and the outer wall of the triangular block conflicts with the extension strip.

[0011] In the aforementioned plastic sheet material that is easy to connect, the upper end of the slide plate is fixedly connected to a connecting column, and the lower end of the traction rope passes through the baffle and is fixedly connected to the connecting column.

[0013] In the aforementioned plastic sheet material that is easy to connect, a blocking piece is fixedly connected to the outer wall of the bottom of the extension column.

[0014] Compared with the existing technology, the advantages of this easy-to-connect plastic sheet are:

[0015] 1. When it is necessary to clean the dirt at the bottom of the PP grille, step on the connecting structure of the area to be cleaned quickly and continuously. The rack drives the counterweight plate to rotate rapidly. When the counterweight plate does not have time to reset under the action of inertia, the rack drives the counterweight plate to rotate again, and continues to reel in the traction rope, thereby driving the traction rope to pull the slide at the bottom, causing the triangular block to hit the extension bar, causing the buckle to disengage from the snap ring. The snap ring pops out under the push of the strong spring, and then props up the PP grille, increasing the space at the bottom of the PP grille to facilitate cleaning of the dirt at the bottom of the PP grille. The dirt can be washed away by simply flushing, making it convenient to clean the dirt;

[0016] 2. After the cleaning is completed, you can slowly step on the connecting structure. The rack will drive the counterweight plate to reel in the traction rope. However, the length of the traction rope is greater than the distance between the counterweight plate and the bottom of the extension bar. As a result, when the counterweight plate slowly rotates and reels in the traction rope, it will not pull the triangular block upward, and the upper edge of the clamping ring will contact the buckle, causing the elastic strip to bend in the direction away from the extension column until the clamping ring moves to the top of the buckle. The elastic strip elastically resets, and the buckle at the bottom presses against the lower edge of the clamping ring, so that the locking structure inside the connecting structure re-locks the ejection structure.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0030] Reference Figures 1-10, a plastic sheet that is easy to connect, including a PP grille 1, with arc grooves 2 opened at the four corners of the PP grille 1, and a connecting structure 3 is installed inside each arc groove 2; the connecting structure 3 includes a vertically arranged outer sleeve 7, and the outer wall of the outer sleeve 7 is fixedly connected to four horizontally arranged shaft columns 5, and the four shaft columns 5 are distributed in a circular array around the outer sleeve 7. An arc clip 4 is opened on the inner side of each arc groove 2, and the inner wall of the arc clip 4 is movably connected to the outer wall of the shaft column 5. The shaft column 5 is limited by the arc clip 4 and is rotatably connected to the arc clip 4. A baffle 29 is fixedly connected to the middle of the outer sleeve 7, and a pressure column 8 is slidably connected to the top of the outer sleeve 7. A reset structure 9 is installed at the bottom of the pressure column 8. The reset structure 9 is a telescopic rod with a reset spring arranged inside. The lower end of the reset structure 9 is fixedly connected to the baffle 29, and the bottom of the pressure column 8 is installed with a trigger structure. The outer wall of the rack 10 is fixedly connected to the inner wall of the outer sleeve 7, and the ratchet structure 11 is fixedly connected to the shaft rod of the outer sleeve 7. The outer wall of the ratchet structure 11 is meshed with the outer wall of the rack 10. When the rack 10 moves downward, the ratchet structure 11 is driven to rotate as a whole. When the rack 10 moves upward, the outer ring of the ratchet structure 11 will rotate accordingly, and the inner ring of the ratchet structure 11 does not rotate. A deep groove 25 is provided on the outer wall of the counterweight plate 12, and a traction rope 13 is fixedly connected to the outer wall of the deep groove 25.

[0031] When the present invention is used, Figure 1-2As shown, the connecting structure 3 is installed in the arc groove 2 at the four corner edges of the PP grille 1. Multiple PP grilles 1 are connected together through the provided connecting structure 3 and spliced into a suitable size according to the actual use area. When it is necessary to clean the dirt at the bottom of the PP grille 1, quickly step on the connecting structure 3 of the area to be cleaned to start the trigger structure, that is, the pressure column 8 moves downward quickly, and is then lifted up and reset by the reset structure 9. When the rack 10 is pressed down, the ratchet structure 11 is driven by the rack 10 to rotate accordingly, and the counterweight plate 12 will rotate synchronously with the ratchet structure 11. When the rack 10 is lifted up and reset by the reset structure 9 The ratchet structure 11 cannot drive the counterweight plate 12 to rotate in the opposite direction. Stepping on it twice quickly will drive the counterweight plate 12 to rotate continuously and reel in the traction rope 13. The reeling in of the traction rope 13 releases the restriction on the ejection structure, so that the ejection structure extends to support the entire outer sleeve 7, and then supports the PP grille 1, increasing the space at the bottom of the PP grille 1 to facilitate cleaning of the dirt at the bottom of the PP grille 1. A simple rinse can wash away the dirt, which facilitates cleaning of the dirt. After cleaning, you can slowly step on the connecting structure 3 to make the locking structure inside the connecting structure 3 re-lock the ejection structure.

[0032] In order to achieve the purpose of locking the ejection structure, the present invention adopts the following technical solution. The ejection structure includes an extension column 15. The top of the extension column 15 is fixedly connected to a limiting ring 27 with a diameter larger than the extension column 15. The top of the extension column 15 is fixedly connected to a strong spring 16. The upper end of the strong spring 16 is fixedly connected to the baffle 29. The bottom of the inner wall of the outer sleeve 7 is fixedly connected to the lower sleeve 14. The inner side of the lower sleeve 14 is provided with a movable groove 30 for limiting the clamping ring 17. The top of the inner side of the lower sleeve 14 is provided with a groove 24. The locking structure is installed inside the groove 24. The locking structure includes an elastic strip 18. The upper end of the elastic strip 18 is fixedly connected to the top of the inner wall of the groove 24. The elastic strip 18 is close to one side of the extension column 15. The side outer wall is fixedly connected with a buckle 19. When the extension column 15 is pressed and moves to the inside of the outer sleeve 7, the buckle 19 limits the snap ring 17. An inclined groove 6 is provided on the outside of the buckle 19. The lower end of the elastic strip 18 is fixedly connected with the extension strip 20. The upper end of the slide 21 is fixedly connected with the connecting column 23. The lower end of the traction rope 13 passes through the baffle 29 and is fixedly connected to the connecting column 23. When locked, after stepping on the connecting structure 3, the upper edge of the snap ring 17 will contact the buckle 19, causing the elastic strip 18 to bend in the direction away from the extension column 15 until the snap ring 17 moves to the top of the buckle 19. The elastic strip 18 elastically resets, and the buckle 19 at the bottom presses against the lower edge of the snap ring 17. The extension column 15 is stuck by the buckle 19 and cannot move.

[0033] In order to achieve the purpose of releasing the restriction of the locking structure on the ejection structure after the traction rope 13 is wound, the present invention adopts the following technical solution, wherein the length of the traction rope 13 is greater than the distance between the counterweight plate 12 and the bottom of the extension bar 20, and the extension bar 20 is provided with a slide 21 on the side close to the extension column 15. The outer wall of the slide 21 on the side close to the extension bar 20 is fixedly connected with a triangular block 22 with a narrow top and a wide bottom. The outer wall of the triangular block 22 conflicts with the extension bar 20. When the connecting structure 3 is slowly stepped on, the rack 10 will drive the counterweight plate 12 to reel in the traction rope 13, but the length of the traction rope 13 is greater than the counterweight plate 12. The distance between the disc 12 and the bottom of the extension bar 20 means that when the counterweight disc 12 rotates slowly and reels in the traction rope 13, it will not pull the triangular block 22 to move upward. When the connecting structure 3 is stepped on quickly, the rack 10 drives the counterweight disc 12 to rotate rapidly. Under the action of inertia, the counterweight disc 12 does not have time to reset. The rack 10 will drive the counterweight disc 12 to rotate again and continue to reel in the traction rope 13, thereby driving the traction rope 13 to pull the slide plate 21 at the bottom, causing the triangular block 22 to contact the extension bar 20, causing the buckle 19 to disengage from the snap ring 17, and the snap ring 17 to pop out under the push of the strong spring 16.

[0034] In order to facilitate stepping on the pressure column 8, the present invention adopts the following technical solution: the top of the outer sleeve 7 is fixedly connected with an upper baffle 28, the outer wall of the pressure column 8 is slidingly connected to the inner wall of the upper baffle 28, and the top of the pressure column 8 is fixedly connected with a pressure plate 31.

[0035] In order to achieve the purpose of increasing the supporting stability of the extension column 15 , the present invention adopts the following technical solution: a blocking piece 26 is fixedly connected to the outer wall of the bottom of the extension column 15 .

[0036] The specific usage method and principle of the present invention are explained in detail below: the connecting structure 3 is installed in the arc groove 2 at the four corner edges of the PP grille 1, and multiple PP grilles 1 are connected together by the provided connecting structure 3, and are spliced into a suitable size according to the actual use area. When it is necessary to clean the dirt at the bottom of the PP grille 1, the connecting structure 3 of the area to be cleaned is stepped on quickly and continuously, and the rack 10 drives the counterweight plate 12 to rotate rapidly. Under the action of inertia, when the counterweight plate 12 has no time to reset, the rack 10 will drive the counterweight plate 12 to rotate again, and continue to reel in the traction rope 13, thereby driving the traction rope 13 to pull the slide plate 21 at the bottom, so that the triangular block 22 hits the extension bar 20, so that the buckle 19 disengages the snap ring 17, and the snap ring 17 pops out under the push of the strong spring 16, thereby propping up the PP grille 1, increasing the The space at the bottom of the PP grille 1 is convenient for cleaning the dirt at the bottom of the PP grille 1. The dirt can be washed away by simple flushing, which makes it convenient to clean the dirt. After cleaning, you can slowly step on the connecting structure 3, and the rack 10 will drive the counterweight plate 12 to reel in the traction rope 13. However, the length of the traction rope 13 is greater than the distance between the counterweight plate 12 and the bottom of the extension bar 20, which causes the counterweight plate 12 to reel in the traction rope 13 when it rotates slowly. It will not pull the triangular block 22 to move upward, and the upper edge of the snap ring 17 will resist the buckle 19, causing the elastic strip 18 to bend in the direction away from the extension column 15 until the snap ring 17 moves to the top of the buckle 19, and the elastic strip 18 elastically resets, and the buckle 19 at the bottom resists the lower edge of the snap ring 17, so that the locking structure inside the connecting structure 3 re-locks the ejection structure.

[0037] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0038] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
