Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical tools, and in particular to a disassembling and assembling tool. BACKGROUND

[0002] In modern industrial production and daily life, screws are widely used. From the assembly of mechanical equipment to the installation of furniture, screws play an indispensable role. With the increasing complexity and diversity of various products, the demand for screw installation and disassembly is also increasing. In many scenarios, multiple screws need to be handled at the same time to improve work efficiency and ensure the consistency of installation. For example, in the fields of automobile manufacturing, electronic equipment assembly, etc., multiple screws often need to be installed or disassembled on a component at the same time. At present, the common screwing tools on the market can only handle one screw at a time. When multiple screws need to be disassembled, workers need to operate one by one, which not only wastes time and effort, but also makes it difficult to ensure the synchronization and efficiency of the operation.

[0003] When disassembling the chip heat sink, there is a method that can handle multiple screws at the same time, that is, by rotating the main gear and the driven gear to drive the screwdriver bit fixed on the driven gear. However, this method can only adapt to the arrangement of screws with fixed spacing and cannot flexibly adjust the distance between screws according to actual needs. This results in a significant reduction in the versatility and applicability of the tool when facing different specifications and different spacing of heat sinks through screws for installation or disassembly tasks. CONTENT OF THE UTILITY MODEL

[0004] Therefore, it is necessary to provide a disassembling and assembling tool that can adapt to screws with different spacing.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0006] A disassembling and assembling tool, the disassembling and assembling tool comprising:

[0007] a housing;

[0008] a plurality of disassembling and assembling parts rotatably mounted on the housing, each of the disassembling and assembling parts being used for plug-in cooperation with a screw head of a screw to limit the disassembling and assembling part and the screw in the circumferential direction;

[0009] a driving part rotatably mounted on the housing;

[0010] a plurality of transmission mechanisms corresponding to the plurality of disassembling and assembling parts one by one, each of the transmission mechanisms being in transmission connection with the corresponding disassembling and assembling part and the driving part to control the corresponding disassembling and assembling part to rotate forward or reverse on the housing under the driving of the driving part;

[0011] The distance between the rotation center line of each of the disassembling members and the rotation center line of the driving member can be adjusted.

[0012] It can be understood that, by setting multiple transmission mechanisms to connect the driving member and the multiple disassembling members one by one, when the disassembling tool is used to disassemble multiple screws, each disassembling member can be first driven to be inserted and fitted with the screw head of the corresponding screw and to achieve circumferential limiting therebetween, and then the driving member is driven to rotate forward or reverse, so that the driving member can be driven to rotate the multiple disassembling members under the transmission of the multiple transmission mechanisms, and finally the purpose of simultaneously screwing the screws is achieved, which is convenient for operation. In this process, the distance between the rotation center line of each disassembling member and the rotation center line of the driving member is adjusted, so that the disassembling tool can be adapted to disassemble multiple screws with different intervals, so that the disassembling tool can cope with the working condition of simultaneously disassembling multiple screws with different intervals.

[0013] In one of the embodiments, the transmission mechanism comprises:

[0014] A first transmission member is rotatably mounted on the housing and in transmission connection with the driving member, and the first transmission member can be driven to rotate on the housing by the driving member;

[0015] A second transmission member is rotatably mounted on the housing and circumferentially limited with the corresponding disassembling member, and the second transmission member can drive the disassembling member to slide on the housing to adjust the distance between the rotation center line of the disassembling member and the rotation center line of the driving member;

[0016] A transmission connection assembly is telescopically mounted on the housing and in transmission connection with the first transmission member and the second transmission member, respectively, and the transmission connection assembly can drive the second transmission member to rotate under the driving of the first transmission member.

[0017] It can be understood that, by telescopically mounting the transmission connection assembly on the housing and connecting the first transmission member and the second transmission member through the transmission connection assembly, the second transmission member is driven to slide through the transmission connection assembly, thereby driving the disassembling member to slide, which can achieve the purpose of adjusting the distance between the rotation center line of the disassembling member and the rotation center line of the driving member, so that the disassembling tool can be used to disassemble multiple screws with different intervals.

[0018] In one of the embodiments, the transmission connection assembly comprises a first gear, an extendable connecting rod and a second gear, the first gear and the second gear are arranged at two ends of the extendable connecting rod and are fixedly connected with the extendable connecting rod respectively, and the second gear can move towards or away from the first gear under the driving of the extendable connecting rod to adjust the distance between the second gear and the first gear.

[0019] The first gear is in transmission connection with the first transmission member and the first transmission member can rotate on the housing under the driving of the first gear, and the second gear is in transmission connection with the second transmission member and the second transmission member can rotate on the housing under the driving of the second gear.

[0020] It can be understood that the first transmission member is connected with the first gear and the second transmission member is connected with the second gear, and the first gear and the second gear are fixedly connected with the extendable connecting rod, so that when the driving member drives the first transmission member to rotate, the first gear is driven and the second gear is driven to rotate through the extendable connecting rod, and finally the second transmission member and the disassembling member are driven to rotate. The transmission connection assembly can adjust the distance between the first gear and the second gear by adjusting the extendable connecting rod, so as to meet the use requirement of adjusting the distance between the rotation center line of the disassembling member and the rotation center line of the driving member.

[0021] In one of the embodiments, the extendable connecting rod is configured as a spring hydraulic rod.

[0022] In one of the embodiments, the disassembling tool further comprises a sliding member, the sliding member is slidingly installed on the housing.

[0023] The second gear, the second transmission member and the disassembling member are all rotatably installed on the sliding member, and the second gear can drive the second transmission member and the disassembling member to slide on the housing through the sliding member.

[0024] It can be understood that by introducing the sliding member, the second gear, the second transmission member and the disassembling member are all installed on the sliding member and can slide on the housing, so that the second gear, the second transmission member and the disassembling member form a relatively independent module which works cooperatively. The sliding member can keep the relative position relationship between the components stable during the transmission process, and can cooperate with the extendable connecting rod to adjust the position of the disassembling member.

[0025] In one of the embodiments, the disassembling member is configured in an extendable structure, and the length of the disassembling member can be adjusted.

[0026] It can be understood that by configuring the disassembling part as a telescopic structure, the applicability of the disassembling tool to different depth positions of the screw is expanded, and the environmental applicability of the disassembling tool is further enhanced.

[0027] In one of the embodiments, the disassembling part comprises a connecting rod body and a screwdriver bit, and the screwdriver bit is detachably mounted on the connecting rod body.

[0028] It can be understood that by detachably mounting the screwdriver bit on the connecting rod body, the screwdriver bit is convenient to replace, and when different types of screws need to be processed, only the corresponding screwdriver bit needs to be replaced, without replacing the entire disassembling part, thereby reducing the use cost and improving the versatility of the disassembling tool.

[0029] In one of the embodiments, the disassembling tool further comprises a hand wheel, which is rotatably mounted on the shell and connected with the driving part in a circumferential limiting manner.

[0030] In one of the embodiments, the disassembling tool further comprises a motor, which is mounted on the shell and drivingly connected with the driving part, for controlling the rotation of the driving part on the shell.

[0031] In one of the embodiments, the number of the disassembling parts and the number of the transmission mechanisms are both four.

[0032] Compared with the prior art, the disassembling tool connects the driving part and the plurality of disassembling parts one by one through the plurality of transmission mechanisms, and when the driving part rotates, the disassembling part can be driven to rotate forward or reverse, the plurality of disassembling parts are circumferentially limited by the screw head plug-in cooperation, so as to realize the disassembly of the screw. By adjusting the distance between each disassembling part and the rotation center line of the driving part, the adaptability of the disassembling tool to different specifications of screws and different installation positions of screws can be increased, so that one tool can cope with multiple working conditions.

DETAILED DESCRIPTION

[0038] In order to make the above objectives, features and advantages of the present application more clear and easily understood, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application can be practiced in a variety of ways beyond the specific embodiments described herein without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0039] It should be noted that when an element is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element, or intervening elements can also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element, or intervening elements can also be present. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar expressions as used in the description of the present application are used for explanation only, and do not indicate the only position of the elements.

[0040] In addition, the terms "first", "second", and the like, are used merely to describe the elements and do not indicate or imply the relative importance or the number of the indicated elements. Thus, a feature with a "first", "second" designation can include at least one of the features, explicitly or implicitly. In the description of the present application, the meaning of "a plurality of" is at least two, such as two, three, etc., unless otherwise specifically limited.

[0041] In the present application, unless otherwise explicitly specified and limited, the "on", "under", "above", and "over" of a first feature to a second feature can be that the first feature is directly in contact with the second feature, or the first feature is indirectly in contact with the second feature through an intermediate medium. Moreover, the "above", "over", and "on" of the first feature to the second feature can be that the first feature is directly above or obliquely above the second feature, or only indicates that the first feature is horizontally higher than the second feature. The "below", "under", and "under" of the first feature to the second feature can be that the first feature is directly below or obliquely below the second feature, or only indicates that the first feature is horizontally lower than the second feature.

[0042] Unless otherwise defined, all technical and scientific terms used in the application's specification have the same meaning as commonly understood by one of ordinary skill in the art to which the application belongs. The terminology used in the application's specification is for describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in the application's specification refers to any or all combinations of one or more of the associated listed items.

[0043] Referring to Figure 1 and Figure 2 , the application provides a disassembling tool 100 for simultaneously disassembling multiple screws, which can be used for disassembling the screws of a radiator and can also be used for disassembling the screws in other fields.

[0044] Specifically, the disassembling tool 100 comprises a housing 10, a plurality of disassembling pieces 20, a driving piece 30, and a plurality of transmission mechanisms 40. The plurality of disassembling pieces 20 are rotatably mounted on the housing 10, and each disassembling piece 20 is used for being insertedly fitted with the screw head of a screw to limit the disassembling piece 20 and the screw in the circumferential direction. The driving piece 30 is rotatably mounted on the housing 10. The plurality of transmission mechanisms 40 correspond to the plurality of disassembling pieces 20 one by one, and each transmission mechanism 40 is in transmission connection with the corresponding disassembling piece 20 and the driving piece 30 to control the forward rotation / reverse rotation of the corresponding disassembling piece 20 on the housing 10 under the driving of the driving piece 30. The distance between the rotation center line of each disassembling piece 20 and the rotation center line of the driving piece 30 can be adjusted.

[0045] As can be seen from the above, the driving piece 30 is connected to the plurality of disassembling pieces 20 one by one through the plurality of transmission mechanisms 40, so that when the disassembling tool is used to disassemble multiple screws, each disassembling piece can be first driven to be insertedly fitted with the screw head of the corresponding screw and to limit the screw and the disassembling piece in the circumferential direction, and then the driving piece 30 can be driven to rotate forward or reverse, so that the driving piece 30 can drive the plurality of disassembling pieces 20 to rotate under the transmission of the plurality of transmission mechanisms 40, and finally the purpose of simultaneously rotating the screws can be achieved. The distance between the rotation center line of each disassembling piece 20 and the rotation center line of the driving piece 30 can be adjusted, so that the disassembling tool 100 can be adapted to the disassembly of multiple screws with different intervals, thereby enabling the disassembling tool 100 to cope with the working condition of simultaneously disassembling multiple screws with different intervals. Here, the number of transmission mechanisms 40 and disassembling pieces 20 can be three, four, five, etc.

[0046] In this embodiment, the number of transmission mechanisms 40 and disassembling pieces 20 is four.

[0047] As Figure 2As shown, the disassembly / assembly component 20 is configured with a telescopic structure, and its length can be adjusted. By configuring the disassembly / assembly component 20 with a telescopic structure, the applicability of the disassembly / assembly tool 100 to working conditions where screws are at different depths is expanded, further enhancing the environmental adaptability of the disassembly / assembly tool 100. For screws that are deeply recessed or protrude from the mounting surface, operation can be made more convenient by adjusting the length of the disassembly / assembly component 20.

[0048] In one embodiment, the disassembly / assembly component 20 includes a connecting rod 21 and a screwdriver bit 22, the screwdriver bit 22 being detachably mounted on the connecting rod 21. By detachably mounting the screwdriver bit 22 on the connecting rod 21, the replacement of the screwdriver bit 22 is facilitated. When dealing with different types of screws, such as Phillips head, slotted head, and hex head screws, only the corresponding screwdriver bit 22 needs to be replaced, without having to replace the entire disassembly / assembly component 20, thus reducing usage costs and improving the versatility of the disassembly / assembly tool 100.

[0049] like Figure 1 As shown, the disassembly / assembly tool 100 also includes a handwheel 31 or a motor (not shown) for controlling the drive component 30. When the handwheel 31 is used to control the drive component 30, the drive component 30 and the handwheel 31 are connected in a circumferential limiting manner. Rotating the handwheel 31 can drive the drive component 30 to rotate, thereby driving the disassembly / assembly component 20 to rotate. When the motor is used to control the drive component 30, the motor is mounted on the housing 10 and is connected to the drive component 30 for transmission, and is used to control the rotation of the drive component 30 on the housing 10.

[0050] In this embodiment, as Figure 1 and Figure 2 As shown, the drive component 30 is connected to the handwheel 31 in a circumferential limiting manner. By rotating the handwheel 31, the drive component 30 is driven to rotate, thereby driving the disassembly and assembly component 20 to rotate, thus realizing the disassembly and assembly of screws.

[0051] In an embodiment, the transmission mechanism 40 comprises a first transmission member 41 rotatably mounted on the housing 10 and in transmission connection with the driving member 30, and the first transmission member 41 is capable of rotating on the housing 10 under the driving of the driving member 30, a second transmission member 42 rotatably mounted on the housing 10 and circumferentially limited with the corresponding dismounting member 20, and the second transmission member 42 is capable of sliding the dismounting member 20 on the housing 10 to adjust the distance between the rotational center line of the dismounting member 20 and the rotational center line of the driving member 30, and a transmission connection assembly 43 telescopically mounted on the housing 10 and in transmission connection with the first transmission member 41 and the second transmission member 42 respectively, and the transmission connection assembly 43 is capable of driving the second transmission member 42 to rotate under the driving of the first transmission member 41. In this way, by telescopically mounting the transmission connection assembly 43 on the housing 10 and connecting the first transmission member 41 and the second transmission member 42 through the transmission connection assembly 43, the second transmission member 42 is driven to slide through the transmission connection assembly 43, thereby driving the dismounting member 20 to slide, so as to adjust the distance between the rotational center line of the dismounting member 20 and the rotational center line of the driving member 30, so that the dismounting member 20 can be used to dismount multiple screws with different intervals.

[0052] Here, the first transmission member 41 and the second transmission member 42 are configured as gear, sprocket, pulley structure to realize transmission connection, and the corresponding parts of the transmission connection assembly 43 and the first transmission member 41 and the second transmission member 42 also adopt corresponding structures, and such transmission connection structures are common in the prior art, which will not be described here.

[0053] In an embodiment, the transmission connection assembly 43 comprises a first gear 431, a telescopic connecting rod 432 and a second gear 433, the first gear 431 and the second gear 433 are arranged at two ends of the telescopic connecting rod 432 and are fixedly connected with the telescopic connecting rod 432 respectively, and the second gear 433 is capable of moving towards or away from the first gear 431 under the driving of the telescopic connecting rod 432 to adjust the distance between the second gear 433 and the first gear 431; wherein the first gear 431 is in transmission connection with the first transmission member 41, and the first transmission member 41 is capable of rotating on the housing 10 under the driving of the first gear 431, the second gear 433 is in transmission connection with the second transmission member 42, and the second transmission member 42 is capable of rotating on the housing 10 under the driving of the second gear 433.

[0054] As can be seen from the above, the first gear 431 is connected to the first transmission member 41, the second gear 433 is connected to the second transmission member 42, and the first gear 431 and the second gear 433 are fixedly connected to the telescopic connecting rod 432, so that when the driving member 30 drives the first transmission member 41 to rotate, the first gear 431 is driven to rotate and the second gear 433 is driven to rotate through the telescopic connecting rod 432, and finally the second transmission member 42 and the disassembling member 20 are driven to rotate. In this way, the distance between the first gear 431 and the second gear 433 can be adjusted by adjusting the telescopic connecting rod 432, so that the distance between the rotation center line of the disassembling member 20 and the rotation center line of the driving member 30 can be adjusted. It can be understood that in other embodiments, the first transmission member 41 can also be integrated into the first gear 431 and configured as the same gear as the first gear 431.

[0055] Further, the extension length of the telescopic connecting rod 432 can be precisely controlled by setting a scale on the telescopic connecting rod 432, so that the distance between the rotation center line of the disassembling member 20 and the rotation center line of the driving member 30 can be better adjusted.

[0056] Here, the telescopic connecting rod 432 can be configured as a plurality of nested hollow rod bodies with different diameters, and positioning can be achieved by setting protrusions and grooves on the rod bodies, or the telescopic connecting rod 432 can be configured as a spring hydraulic rod.

[0057] In an embodiment, the disassembling tool 100 further comprises a sliding member 50 which is slidingly mounted on the housing 10; wherein the second gear 433, the second transmission member 42 and the disassembling member 20 are all rotatably mounted on the sliding member 50, and the second gear 433 can drive the second transmission member 42 and the disassembling member 20 to slide on the housing 10 through the sliding member 50. By introducing the sliding member 50, the second gear 433, the second transmission member 42 and the disassembling member 20 are all mounted thereon and can slide on the housing 10, so that the second gear 433, the second transmission member 42 and the disassembling member 20 form a relatively independent module that works cooperatively. The relative positional relationship between the components can be kept stable during transmission by the sliding member 50, and the position of the disassembling member 20 can be adjusted in cooperation with the telescopic connecting rod 432.

[0058] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present disclosure.

[0059] The above-described embodiments are merely illustrative of several embodiments of the present application, which are described in more detail and in a specific manner, but should not be construed as limiting the scope of the patent application. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
