[0033] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0034] The following describes the noun part of the wall corner waterproof layer compacting device 100 according to the present application with reference to the accompanying drawings.

[0035] like Figure 1 and Figure 2As shown, on the one hand, the present application provides a wall corner waterproof layer compacting device 100, comprising a control rod 1, a connecting pressure head 2 and a plurality of corner edge compacting structures 4, wherein the connecting pressure head 2 is connected to one end of the control rod 1, and the outer periphery of the connecting pressure head 2 is formed with a corner end compacting structure 3 for compacting the corner end of the wall corner waterproof layer; the plurality of corner edge compacting structures 4 are connected to the outer periphery of the connecting pressure head 2 in sequence at intervals along the circumferential direction and extend outward from the outer periphery of the connecting pressure head 2 respectively, and the corner end compacting structure 3 is located between two corner edge compacting structures 4 which are adjacent to each other along the circumferential direction and are respectively used to compact the two corner edges of the wall corner waterproof layer.

[0036] It should be noted that a corner is formed at the junction of two adjacent walls. The waterproof layer covering the corner is a corner waterproof layer. The corner waterproof layer includes a corner end portion located in the middle and wrapping the corner, and two corner edges located on both sides of the corner end portion. The two corner edges respectively cover the walls on both sides of the corner.

[0037] It can be seen that in the specific embodiment of the present application, the corner end and corner edge of the corner waterproof layer are compacted simultaneously by using the corner end compaction structure 3 and the corner edge compaction structure 4, thereby avoiding hollowing between the corner end and corner edge of the corner waterproof layer and the corner, and then the corner waterproof layer is firmly adhered to the corner to improve the waterproof effect.

[0038] Furthermore, in the specific embodiment of the present application, the corner end compaction structure 3 is directly formed on the connecting pressure head 2. Since the connecting pressure head 2 itself has a relatively high strength, the corner end compaction structure 3 is not easily damaged during transportation, carrying and storage, which is beneficial to the long-term storage and use of the corner waterproof layer compaction device 100, thereby improving the durability and practicality of the corner waterproof layer compaction device 100.

[0039] Preferably, the connecting pressure head 2 is made of high-strength hard material, and the wear resistance of the corner end compaction structure 3 is enhanced by directly setting the corner end compaction structure 3 on the connecting pressure head 2 with higher strength, thereby extending the service life of the corner waterproof layer compaction device 100.

[0040] In actual construction, the wall corners are divided into inner corners (recessed corners) and outer corners (convex corners). In the specific embodiment of the present application, two corner end compaction structures 3 are also provided to compact the wall corner waterproofing layer of the inner corner and the outer corner respectively.

[0041] Specifically, the corner end compacting structure 3 applicable to the external corner is a external corner buckle groove, which is used to buckle with the corner end of the external corner; the corner end compacting structure 3 applicable to the internal corner is a internal corner plugging block, which is used to plug with the corner end of the internal corner. In the specific embodiment of the present application, two types of corner end compacting structures 3 are provided on the same connecting pressure head 2 to be applicable to different wall corners, thereby improving the application range of the wall corner waterproof layer compacting device 100.

[0042] It will be understood by those skilled in the art that a compacting device for the internal corner waterproof layer specifically for compacting the internal corner waterproof layer and a compacting device for the external corner waterproof layer specifically for compacting the external corner waterproof layer may also be provided.

[0043] In some embodiments, the pressing construction surface of the corner end compaction structure 3 and the axial end surface are connected via a chamfered portion or a rounded portion.

[0044] It should be noted that the corner end compaction structure 3 is arranged on the outer periphery of the connecting pressure head 2, and the crimping construction surface of the corner end compaction structure 3 refers to the contact surface between the corner end compaction structure 3 and the wall corner. It can be seen that the crimping construction surface is formed on the outer periphery of the connecting pressure head 2, which is equivalent to the crimping construction surface being a small section of the outer periphery of the connecting pressure head 2 along the circumferential direction. Generally speaking, the axial end face of the connecting pressure head 2 and the outer periphery of the connecting pressure head 2 are perpendicular to each other. Then, when the crimping construction surface is compacting the wall corner waterproof layer, the connecting pressure head 2 needs to move along the wall height direction, and the connection between the crimping construction surface and the axial end face will contact the wall corner waterproof layer. In a specific embodiment of the present application, a chamfered portion or a rounded corner is provided between the connecting construction surface and the axial end face for connection, thereby avoiding wear on the wall corner waterproof layer, thereby improving the practicality of the wall corner waterproof layer compaction device 100.

[0045] In some embodiments, the outer periphery of the connecting pressure head 2 is also formed with a plurality of slots 5 arranged in sequence along the circumferential direction, and the corner edge compaction structure 4 is provided with an insertion rod 6, and the corner edge compaction structure 4 is connected to the connecting pressure head 2 through the detachable plug-in cooperation between the insertion rod 6 and the slots 5.

[0046] It can be seen that the slot 5 is directly arranged inside the connecting pressure head 2. Since the connecting pressure head 2 itself has high strength, the slot 5 as the connecting structure between the corner compaction structure 4 and the connecting pressure head 2 is not easily damaged, and the strength of the slot 5 is consistent with that of the connecting pressure head 2, so it has better wear resistance.

[0047] Furthermore, the corner compaction structure 4 is detachably connected to the connecting pressure head 2 via the insertion rod 6. Even if the corner compaction structure 4 or the insertion rod 6 is damaged during use, it can be continued to be used by simply replacing a new corner compaction structure 4 or the insertion rod 6, thereby improving the practicality of the entire wall corner waterproofing layer compaction device 100.

[0048] Preferably, the wall corner waterproof layer compacting device 100 also includes a slot magnetic structure 9 arranged in the slot 5, and the corner edge compacting structure 4 also includes a rod magnetic portion arranged on the rod 6, and the rod 6 and the slot 5 are magnetically connected to the slot magnetic structure 9 through the rod magnetic portion.

[0049] The use of magnetic connection is a simple and reliable connection method, which does not require additional processing on the shape of the insertion rod 6 and the slot 5, thereby improving the reliability of the connection between the corner compaction structure 4 and the connecting pressure head 2. The magnetic connection method can realize the rapid separation of the insertion rod 6 and the slot 5, thereby realizing the rapid disassembly and assembly of the corner compaction structure 4 and the connecting pressure head 2.

[0050] Specifically, the magnetic attraction portion of the insertion rod is arranged at the end of the insertion rod 6, and the magnetic attraction structure 9 of the slot is arranged in the slot 5. When connecting the corner and edge compaction structure 4 and the connecting pressure head 2, the insertion rod 6 is inserted into the slot 5, and the magnetic attraction portion of the insertion rod and the magnetic attraction structure 9 of the slot attract each other; when separating the corner and edge compaction structure 4 and the connecting pressure head 2, it is necessary to provide a force sufficient to pull out the insertion rod 6.

[0051] It is understood by those skilled in the art that the magnetic attraction portion of the plug rod and the magnetic attraction structure 9 of the slot can both be made of magnets, or one of them can be made of iron and the other can be made of magnets. When the magnetic attraction portion of the plug rod is made of iron, the magnetic attraction portion of the plug rod and the plug rod 6 can be made into one piece, that is, the plug rod 6 itself is made of iron, thereby reducing the number of parts required to be manufactured to facilitate manufacturing.

[0052] In some embodiments, the cross-sectional outer contour of the insertion rod 6 and the cross-sectional outer contour of the slot 5 are both the same polygon.

[0053] Those skilled in the art can understand that the polygon can be any of various polygons such as a triangle, a quadrilateral, a pentagon, etc. The polygonal setting can avoid relative rotation between the insertion rod 6 and the connecting pressure head 2, thereby improving the practicality of the corner waterproofing layer compacting device 100. Moreover, compared with the circular cross-sectional outer contour, the polygonal cross-sectional outer contour can make the two difficult to separate.

[0054] Preferably, the cross-sectional outer contours of the insertion rod 6 and the cross-sectional outer contours of the slot 5 are both regular hexagons. The regular hexagonal deformation not only increases the contact area between the insertion rod 6 and the slot 5, but also facilitates actual production.

[0055] In some embodiments, the outer periphery of the connecting pressure head 2 is formed with a plurality of corner end compaction structures 3 arranged in sequence along the circumferential direction, and each corner end compaction structure 3 is provided with two slots 5 on both sides of the circumference, and the insertion rod 6 of each corner edge compaction structure 4 is selectively inserted into the plurality of slots 5.

[0056] Specifically, each corner end compaction structure 3 is grouped with two slots 5 on both sides of the circumference of the corner end compaction structure 3. After the insertion rod 6 of the corner edge compaction structure 4 is plugged into the slot 5, it is equivalent to that the two corner edge compaction structures 4 are grouped with the corner end compaction structure 3 located between the two corner edge compaction structures 4. The corner end compaction structure 3 and the two corner edge compaction structures 4 of the same group perform compaction operations on the same corner waterproof layer, and the two corner edge compaction structures 4 of the same group are respectively in contact with the two corner edges of the same corner waterproof layer.

[0057] Furthermore, only one slot 5 may be provided between two adjacent corner end compacting structures 3 , that is, this slot 5 serves as a common slot 5 of the two adjacent corner end compacting structures 3 , thereby reducing the number of slots 5 on the connecting pressure head 2 and further simplifying the processing of the connecting pressure head 2 .

[0058] It should be noted that the multiple corner end compacting structures 3 on the connecting pressure head 2 can be used to crimp corner ends of the wall corner waterproof layer at different angles, such as corner ends of 90°, 120°, 135°, etc. In other words, multiple corner end compacting structures 3 suitable for corner ends at different angles can be set on the same connecting pressure head 2 to expand the applicable scenarios of a single wall corner waterproof layer compacting device 100, so that different corner end compacting structures 3 can be switched to perform compaction work on corner ends with different angles.

[0059] In some embodiments, when compacting the corner waterproof layer, the operator needs to hold the control rod 1 and reciprocate the connecting pressure head 2 along the height direction of the wall until the corner waterproof layer is well attached to the wall.

[0060] Preferably, the control rod 1 and the connecting pressure head 2 are detachably connected. In other words, during the carrying, transportation and storage of the corner waterproof layer compacting device 100, the control rod 1 and the connecting pressure head 2 are separated to reduce the occupied space and further improve the practicality of the corner waterproof layer compacting device 100.

[0061] Furthermore, a threaded connection column is provided at one end of the control rod 1, and a threaded connection groove matching with the threaded connection column is formed on the connecting head 2. The threaded connection method can facilitate the installation and removal of the control rod 1 and the connecting head 2, and has good stability after connection.

[0062] Those skilled in the art will appreciate that the connection method between the control lever 1 and the connecting pressure head 2 can also be an interference fit connection or a spring clip is provided at the end of the control lever 1, and a slot is provided on the connecting pressure head 2. In addition to the above methods, other methods that can achieve a detachable connection between the control lever 1 and the connecting pressure head 2 also fall within the scope of protection of the present application.

[0063] Furthermore, the control rod 1 and the connecting pressure head 2 may also be connected in an integrally formed manner, thereby improving the overall strength of the control rod 1 and the connecting pressure head 2 and preventing them from being damaged during use.

[0064] An exemplary embodiment of the present application is provided below, which specifically discloses a specific structure of a corner waterproofing layer compacting device 100, wherein the directional words used, such as "up, down, left, right, front, and back", are usually relative to the directions shown in the drawings, and the position descriptor used, "inside", refers to the inside of the component, and the position descriptor used, "outside" refers to the outside of the component.

[0065] Specifically, the connecting pressure head 2 includes a pressure head disc portion 21 and a pressure head convex portion protruding outward from the outer periphery of the pressure head disc portion 21, the control lever 1 and multiple corner edge compaction structures 4 are all connected to the pressure head disc portion 21, and the corner end compaction structure 3 is formed on the pressure head convex portion.

[0066] Among them, the number of the ram convex parts is two and they are the first ram convex part 22 and the second ram convex part 23 respectively. The first ram convex part 22 is arranged at the front end of the connecting ram 2, and the second ram convex part 23 is arranged at the rear end of the connecting ram 2. The corner end compaction structure 3 on the first ram convex part 22 is the first corner end compaction structure 31, and the corner end compaction structure 3 on the second ram convex part 23 is the second corner end compaction structure 32. The left and right sides of the first ram convex part 22 are respectively provided with first slots, and the left and right sides of the second ram convex part 23 are respectively provided with second slots. The corner edge compaction structure 4 plugged into the first slot is the first corner edge compaction structure 4, and the corner edge compaction structure 4 plugged into the second slot is the second corner edge compaction structure 4. The control rod 1 is connected to the lower end surface of the ram disc part 21, and the central axis of the control rod 1 coincides with the central axis of the ram disc part 21.

[0067] Specifically, the first corner end compaction structure 31 is a male corner buckle groove suitable for a 90° male angle, and the second corner end compaction structure 32 is a male corner buckle groove suitable for a 120° male angle. The center lines of the first corner end compaction structure 31 and the second corner end compaction structure 32 extending in the front-to-back direction coincide with the same radial straight line extending in the front-to-back direction of the pressure head disc portion 21, which is the first radial straight line 7. The two first slots are symmetrically arranged on the left and right sides of the first radial straight line 7. The pressure head disc portion 21 also includes a second radial straight line 8 extending in the left-right direction and perpendicular to the first radial straight line 7. The two first slots are located in front of the second radial straight line 8, and the two second slots are located in the rear of the second radial straight line 8. The central axis angle of the two first slots is 90°, and the central axis angle of the two second slots is 120°. After the two insertion rods 6 are respectively inserted into the two first slots, the central axis angle of the two insertion rods 6 is 90°. After the two insertion rods 6 are respectively inserted into the two second slots, the central axis angle of the two insertion rods 6 is 120°.

[0068] Furthermore, the corner edge compaction structure 4 uses a roller coaxially sleeved with the insertion rod 6, and the roller rotates with the insertion rod 6 as the rotation axis. After the insertion rod 6 is inserted into the slot 5, the outer surface of the roller is flush with the adjacent groove wall of the corresponding positive corner buckle groove. When the positive corner buckle groove is buckled with the corner end, the outer surface of the roller fits with the corner waterproof layer. During the movement of the connecting pressure head 2, the roller rolls on the corner waterproof layer to perform compaction operations on the corner edge. For example, the outer surface of the roller located on the left side of the first corner end compaction structure 31 is flush with the left groove wall of the first corner end compaction structure 31.
