Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, and in particular to a quick disassembly device, a quick disassembly assembly and an electric tool. Background Art

[0002] As an electric cutting tool, electric saw is mainly used to cut wood, stone, certain metal materials, etc. It is an important electric tool with a wide range of applications. Handheld electric saws are increasingly favored by construction workers because of their advantages such as easy portability, ease of operation, and great flexibility.

[0003] However, the existing power tools are of an integrated structure, and the power head and the functional head are assembled together by multiple screws, which is not easy to disassemble. When the power head needs to be disassembled from the functional head, the screws need to be turned multiple times to separate the power head from the functional head, which is inconvenient and time-consuming to disassemble. Summary of the invention

[0004] In order to solve the problem that the existing electric tools are inconvenient to disassemble due to their integrated structure, the present invention provides a quick disassembly device, comprising: a mounting portion, which is provided with a mounting space inside; a clamping portion, which is rotatably arranged on the mounting portion; and a locking portion, which is arranged on the clamping portion and is used to lock the clamping portion; wherein the clamping portion can extend into or withdraw from the mounting space.

[0005] The technical effect achieved after adopting this technical solution is as follows: during the installation process, the clamping part can be driven to extend into or withdraw from the installation space by simply rotating the clamping part, thereby quickly locking the equipment to be installed in the installation space; compared with the assembly method using multiple screws, the structural design is more reasonable, and the operation is simpler, faster and more labor-saving.

[0006] In this embodiment, the mounting part includes: a mounting body, which has a accommodating space inside; a mounting seat, which is arranged on a side of the mounting body away from the accommodating space; and a first rotating shaft, which axially connects the mounting seat and the clamping part; wherein the clamping part can rotate relative to the mounting seat via the first rotating shaft.

[0007] The technical effect achieved by adopting this technical solution is that since the clamping part is rotatably arranged on the mounting body through the first rotating shaft, during the process of disassembling the power head, the clamping part can be rotated into or out of the accommodation space by driving the clamping part to rotate relative to the mounting body with the first rotating shaft as the axis. Compared with the method of matching the clamping slot and the buckle, this structure only needs to rotate the clamping part, the operation steps are simpler, the disassembly and installation speed is faster, and the efficiency is higher.

[0008] In this embodiment, the clamping portion includes: a pull end, which is arranged at one end of the clamping portion; a clamping end, which is arranged at an end of the clamping portion away from the pull end and connected to the first rotating shaft; and a clamping boss, which is arranged on the clamping end and extends in a direction away from the clamping end.

[0009] The technical effect achieved after adopting this technical solution is: by setting a lever end at the end of the clamping part away from the clamping groove, the construction personnel can hold the lever end with their hands during the installation or disassembly process, and then drive the clamping end to rotate through the lever end to screw the clamping boss into or out of the accommodating space, thereby realizing rapid disassembly of the equipment to be installed and the installation part.

[0010] In this embodiment, the locking portion is rotatably disposed between the pulling end and the clamping end, and is used to lock the pulling end.

[0011] The technical effect achieved after adopting this technical solution is as follows: since a locking part is provided on the side of the pull end close to the clamping end, the clamping part can be locked after the power head and the functional head are assembled to avoid accidental touching of the clamping part during operation, causing the clamping part to be rotated out of the accommodating space, thereby improving the installation firmness of the quick disassembly device.

[0012] In this embodiment, the locking portion includes: a first locking piece, rotatably arranged between the pulling end and the clamping end, and provided with a hook; a second locking piece, fixedly arranged on one side of the first locking piece, and provided with an extension plate; wherein, when the extension plate is clamped in the hook, the pulling end is locked.

[0013] The technical effect achieved after adopting this technical solution is: the locking part is set in the form of a first locking part and a second locking part. When the connecting device and the installation part are assembled, the protruding plate of the second locking part can be set in the lock hook of the first locking part, so that the clamping part can be locked, avoiding the construction personnel from accidentally rotating the clamping part out of the accommodating space, causing the equipment to be installed to fall off from the quick disassembly device.

[0014] In this embodiment, the first locking member includes: a first locking body, which is axially connected to the clamping portion and has a pressing member at one end; a first elastic member, which is arranged between the pressing member and the clamping portion; wherein the hook is arranged at an end of the first locking body away from the pressing member.

[0015] The technical effect achieved after adopting this technical solution is as follows: when the connecting device and the mounting part are assembled, the first locking body can be driven to rotate by pressing the push piece, so that the hook rotates to the bottom of the extension plate, and the clamping part is locked, thereby preventing construction personnel from accidentally touching the pulling end of the clamping part and pulling it up; since a first elastic member is provided between the push piece and the clamping part, after the locking is completed, the first elastic member can give the first locking body a rebound force, thereby preventing the first locking body from rotating due to the action of gravity, causing the hook and the extension plate to separate from each other, resulting in the problem that the locking of the clamping part is released.

[0016] In this embodiment, the second locking member includes: a second locking body, which is arranged on one side of the first locking body; a second elastic member, one end of which is sleeved on the second locking body and the other end is arranged below the clamping end; wherein the extending plate is sleeved on the second locking body and is located above the second elastic member.

[0017] The technical effect achieved after adopting this technical solution is: since a second elastic member is arranged below the clamping end, when the pulling end of the clamping part is pulled up, the second elastic member can give a rebound force to the bottom of the clamping end, thereby preventing the clamping part from rotating due to gravity and causing the pulling end to fall off.

[0018] In this embodiment, a quick disassembly assembly is provided, comprising: a quick disassembly device as described in any of the previous embodiments; a connecting device, which is movably arranged in the installation space and is provided with a snap-in groove; wherein, when the connecting device is arranged in the installation space, the snap-in portion can extend into or out of the snap-in groove.

[0019] The technical effect achieved after adopting this technical solution is as follows: since the connecting device is provided with a clamping groove, and the mounting portion is provided with a corresponding clamping portion, the power head and the functional head can be quickly disassembled and installed through the coordinated installation of the clamping groove and the clamping portion. When the power head needs to be disassembled, the clamping portion can be withdrawn from the clamping groove, thereby realizing the rapid disassembly of the connecting device and the mounting portion, and then realizing the rapid disassembly of the power head and the functional head; when the power head needs to be installed, the clamping portion can be extended into the clamping groove, thereby realizing the rapid installation of the connecting device and the mounting portion, and then realizing the rapid installation of the power head and the functional head.

[0020] In this embodiment, the quick disassembly assembly also includes a guide device arranged between the connecting device and the quick disassembly device, and the guide device includes: a first guide portion, which is arranged on the connecting device, and at least one second guide portion, which is surrounded in the installation space and installed in cooperation with the first guide portion.

[0021] The technical effect achieved after adopting this technical solution is as follows: by setting the first guide part and the second guide part, the matching installation between the quick-detachable device and the connecting device can be guided, thereby reducing the alignment time, improving the installation speed and installation efficiency between the quick-detachable device and the connecting device, and realizing rapid disassembly and assembly between the quick-detachable device and the connecting device.

[0022] An embodiment of the present invention provides an electric tool, which includes: a functional head; a power head, which is arranged on one side of the functional head and is drivingly connected to the functional head; and a quick-disassembly assembly as described in any of the previous embodiments; wherein the quick-disassembly assembly is arranged between the power head and the functional head, and the power head is detachably arranged on the functional head through the quick-disassembly assembly.

[0023] The technical effect achieved after adopting this technical solution is as follows: Since a quick-disassembly device is provided between the functional head and the power head, when multiple electric tools are required for construction operations, only one power head needs to be configured, and then the power head is matched with different functional heads through the quick-disassembly device to provide driving force for multiple power heads, thereby improving the applicability of the power head and reducing the construction operation cost.

[0024] In addition, when the power head is damaged, the connecting device can be quickly removed from the mounting portion, thereby quickly removing the power head from the power tool, repairing or replacing the power head, and then quickly installing the repaired or replaced power head on the functional head through the quick removal device, without replacing the entire power tool, thereby reducing the maintenance cost of the operating equipment.

[0025] In summary, the above embodiments of the present application may have one or more of the following advantages or beneficial effects:

[0026] (1) During the installation process, the clamping portion can be driven to extend into or withdraw from the installation space by simply rotating the clamping portion, thereby quickly locking the device to be installed in the installation space; compared with the assembly method using multiple screws, the structural design is more reasonable, and the operation is simpler, faster and more labor-saving.

[0027] (2) Since a locking portion is provided on the side of the trigger end close to the clamping end, the clamping portion can be locked after the power head and the functional head are assembled, thereby preventing the clamping portion from being accidentally touched during operation, causing the clamping portion to be screwed out of the clamping groove and affecting the normal cutting operation of the power tool. This improves the installation firmness of the power tool and ensures the operating stability of the power tool. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] [First embodiment]

[0043] See also Figure 1 , the quick disassembly device 100, for example, includes: a mounting portion, a clamping portion 20 and a locking portion 30. Among them, a accommodating space 11 is provided inside the mounting portion; the clamping portion 20 is rotatably provided on the mounting portion. The locking portion 30 is rotatably provided on the clamping portion 20, and is used to lock the clamping portion 20. Specifically, when the quick disassembly device 100 is working, the device to be installed is provided in the accommodating space 11 of the mounting portion, and the clamping portion 20 only needs to be rotated into the accommodating space 11 to clamp the device to be installed provided in the accommodating space 11, so that the device to be installed is firmly clamped in the accommodating space 11 of the mounting portion; when it is necessary to disassemble the device to be installed, the clamping portion 20 only needs to be rotated out of the accommodating space 11 to release the lock of the quick disassembly device 100 on the device to be installed, and the device to be installed can be quickly disassembled.

[0044] Specifically, a corresponding installation groove is provided on the clamping part 20, and the locking part 30 is embedded in the installation groove. By providing the locking part 30 on the quick disassembly assembly 300, it is possible to avoid the problem that the clamping part 20 is accidentally touched during the construction work, causing the clamping part 20 to be rotated out of the accommodation space 11, so that the equipment to be installed falls off from the quick disassembly device 100, thereby ensuring the assembly firmness between the equipment to be installed and the quick disassembly device 100.

[0045] Further, combined with Figures 1 to 5The mounting portion includes, for example, a mounting body 12, a mounting seat 13, and a first rotating shaft 14. The mounting body 12 has an accommodation space 11 inside; the mounting seat 13 is disposed on a side of the mounting body 12 away from the accommodation space 11; and the first rotating shaft 14 axially connects the mounting seat 13 and the clamping portion 20. Specifically, the clamping portion 20 can rotate relative to the mounting seat 13 via the first rotating shaft 14.

[0046] Further, combined with Figure 4 The clamping portion 20 includes, for example, an actuating end 21, a clamping end 22, and a clamping boss 23. The actuating end 21 is disposed at one end of the clamping portion 20; the clamping end 22 is disposed at an end of the clamping portion 20 away from the actuating end 21; the first rotating shaft 14 is located between the actuating end 21 and the clamping end 22; the clamping boss 23 is disposed at the clamping end 22 and extends in a direction away from the clamping end 22. Specifically, the actuating end 21 can drive the clamping end 22 to rotate clockwise or counterclockwise around the first rotating shaft 14, thereby driving the clamping boss 23 to rotate into or out of the accommodation space 11.

[0047] In a specific embodiment, Figure 4 When it is necessary to remove the equipment to be installed, the clamping end 22 can be driven by the pulling end 21 to rotate counterclockwise around the first rotating shaft 14, so that the clamping boss 23 is screwed out of the accommodating space 11 to release the lock between the quick-disassembly device 100 and the equipment to be installed, and then the equipment to be installed is taken out from the accommodating space 11 to remove the equipment to be installed; when it is necessary to quickly install the equipment to be installed, the equipment to be installed can be inserted into the accommodating space 11, and then the clamping end 22 can be driven by the pulling end 21 to rotate clockwise around the first rotating shaft 14, so that the clamping boss 23 is screwed into the accommodating space 11 to complete the locking between the equipment to be installed and the quick-disassembly device 100, and the equipment to be installed is firmly installed on the quick-disassembly device 100.

[0048] Further, combined with Figure 4 The locking part 30 includes, for example, a first locking member 31, a second locking member 32 and a second rotating shaft 35. The first locking member 31 is rotatably disposed between the pull end 21 and the clamping end 22 via the second rotating shaft 35, and a hook 33 is disposed on the first locking member 31; the second locking member 32 is fixedly disposed on one side of the first locking member 31, and a protruding plate 34 is disposed on the second locking member 32. Specifically, when the protruding plate 34 is clamped in the hook 33, the pull end 21 is locked.

[0049] In a specific embodiment, after the locking boss 23 is screwed into the accommodating space 11, the first locking piece 31 can be rotated clockwise with the second rotating shaft 35 as the axis, thereby driving the hook 33 to rotate in the direction close to the protruding plate 34, until the protruding plate 34 is locked in the hook 33, and the locking of the locking portion 20 is completed; when it is necessary to dismantle the equipment to be installed, first rotate the first locking piece 31 counterclockwise with the second rotating shaft 35 as the axis, thereby driving the hook 33 to rotate in the direction away from the protruding plate 34, until the protruding plate 34 is disengaged from the hook 33, and the locking of the locking portion 20 is released, and then the locking boss 23 can be screwed out of the accommodating space 11.

[0050] The locking portion 30 is configured to cooperate with a first locking piece 31 and a second locking piece 32. When the equipment to be installed is assembled with the quick-release device 100, the lever end 21 of the clamping portion 20 can be locked by the cooperation between the hook 33 on the first locking piece 31 and the protruding plate 34 on the second locking piece 32. This can prevent construction workers from accidentally touching the lever end 21 during operation, causing the clamping boss 23 to be rotated out of the clamping groove 210, resulting in the equipment to be installed falling off the quick-release device 100.

[0051] Further, combined with Figure 4 and Figure 5 The first locking member 31 includes, for example, a first locking body 36 and a first elastic member (not shown). The first locking body 36 is axially connected to the clamping portion 20 via the second rotating shaft 35, and a pressing member 37 is provided at one end of the first locking body 36; the first elastic member is provided between the pressing member 37 and the clamping portion 20; and the hook 33 is provided at one end of the first locking body 36 away from the pressing member 37.

[0052] In a specific embodiment, the first elastic member is a torsion spring. Due to the rebound force of the torsion spring, the first locking member 31 always tends to rotate clockwise around the second rotating shaft 35 when no external force is applied, so that the upper end surface of the hook 33 is always in close contact with the lower end surface of the extension plate 34. Only when a certain degree of force is continuously applied to the push member 37, the first locking member 31 can be driven to rotate counterclockwise around the second rotating shaft 35, so that the extension plate 34 is separated from the hook 33. If it is just an accidental touch and the push member 37 is slightly pressed, the rebound force of the torsion spring will quickly drive the first locking member 31 to reset, and the extension plate 34 and the hook 33 will not be separated from each other.

[0053] Furthermore, the second locking member 32 includes, for example, a second locking body 38 and a second elastic member (not shown in the figure). The second locking body 38 is disposed on one side of the first locking body 36; one end of the second elastic member is sleeved on the second locking body 38, and the other end is disposed below the clamping end 22; the extension plate 34 is sleeved on the second locking body 38 and is located above the second elastic member.

[0054] In a specific embodiment, the second elastic member is an elastic gasket. The elastic gasket is provided with a U-shaped groove at one end below the clamping end 22, the upper end surface of the U-shaped groove is always in close contact with the lower end surface of the clamping end 22, and the clamping boss 23 is provided in the U-shaped groove. Specifically, the length of the clamping boss 23 is greater than the thickness of the elastic gasket, so the clamping boss 23 can extend out of the U-shaped groove and be clamped in the accommodating space 11.

[0055] By providing the elastic gasket at the bottom of the clamping end 22, on the one hand, when the clamping portion 20 rotates, the lower end surface of the clamping end 22 can be prevented from directly contacting the upper end surface of the clamping groove 210, thereby reducing the wear of the lower end surface of the clamping end 22 (the material of the clamping end 22 is plastic), and improving the service life of the clamping end 22. On the other hand, the elastic gasket can provide an upward rebound force to the lower end surface of the clamping end 22. When the pull end 21 is rotated counterclockwise around the first rotating shaft 14 to rotate the clamping boss 23 out of the accommodating space 11, the rebound force can support the lower end surface of the clamping end 22, thereby preventing the pull end 21 from rotating clockwise around the first rotating shaft 14 and falling due to the action of gravity.

[0056] [Second embodiment]

[0057] See also Figure 6 , which is a schematic diagram of the structure of an electric tool 600 provided in an embodiment of the present invention. The electric tool 600 includes, for example, a functional head 400, a power head 500, and a quick disassembly assembly 300. The power head 500 is arranged on one side of the functional head 400, and is driven to connect the functional head 400; the quick disassembly assembly 300 is arranged between the functional head 400 and the power head 500. Specifically, the power head 500 is detachably arranged on the functional head 400 through the quick disassembly assembly 300.

[0058] In a specific embodiment, when the power head 500 fails or is damaged, the power head 500 can be quickly disassembled from the driving force input end of the functional head 400 through the quick disassembly assembly 300 to repair or replace the power head 500; and then the normal power head 500 can be quickly assembled to the functional head 400 through the quick disassembly assembly 300 to continue the cutting operation. There is no need to replace the entire power tool 600 like an integrated electric saw, thereby reducing the equipment investment cost of the cutting operation.

[0059] In addition, according to actual operation needs, the power head 500 can be quickly installed on various types of functional heads 400 through the quick disassembly assembly 300, that is, one power head 500 can be used with multiple functional heads 400, thereby further reducing the equipment investment cost of the cutting operation. For example, the functional head 400 can be a reciprocating saw, or a jig saw, a miter saw, or other cutting equipment, which is not limited here.

[0060] Further, combined with Figures 7 to 10 The quick disassembly assembly 300 includes, for example, a quick disassembly device 100 and a connection device 200. The connection device 200 is movably disposed in the accommodation space 11 and is provided with a clamping groove 210. When the quick disassembly device 100 and the connection device 200 are cooperatively installed, the connection device 200 is disposed in the accommodation space 11, and the clamping portion 20 is clamped in the clamping groove 210.

[0061] Further, the connection device 200 is arranged on a side of the power head 500 close to the functional head 400, and the quick release device 100 is arranged on the driving force input side of the functional head 400. Specifically, the quick release device 100 and the connection device 200 are detachably connected.

[0062] In a specific example, the connection device 200 is provided with a clamping groove 210, and the quick-release device 100 is provided with a corresponding clamping portion 20. The quick-release device 100 can extend into or out of the clamping groove 210 through the clamping portion 20. For example, the locking between the quick-release device 100 and the connection device 200 can be released by controlling the clamping portion 20 to withdraw from the clamping groove 210, so that the connection device 200 can be quickly removed from the quick-release device 100; in addition, the quick-release device 100 and the connection device 200 can be locked by controlling the clamping portion 20 to extend into the clamping groove 210, so that the connection device 200 can be quickly assembled to the functional head 400.

[0063] Preferably, the clamping groove 210 is a through groove provided on the quick disassembly device 100. In the production process of parts, this form of design is convenient for processing and manufacturing.

[0064] Furthermore, the electric tool 600, for example, further includes: a first guide portion 15 and a second guide portion 220. Among them, at least one first guide portion 15 is arranged on the quick-release device 100; the second guide portion 220 is arranged on the connecting device 200, and is installed in cooperation with the first guide portion 15. Specifically, the second guide portion 220 is arranged in the accommodating space 11. By arranging the first guide portion 15 and the second guide portion 220, the cooperative installation between the quick-release device 100 and the connecting device 200 can be guided and pre-positioned, thereby reducing the time for alignment and improving the installation speed and efficiency of the power head 500, and realizing the rapid disassembly and assembly between the power head 500 and the functional head 400.

[0065] In a specific embodiment, the first guide portion 15 is a positioning boss, and the second guide portion 220 is a positioning plate. When the functional head 400 and the power head 500 are installed in cooperation, the positioning boss is installed into the quick-release device 100 along the length direction of the positioning plate.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
