Description

Technical Field

[0001] The present application relates to the field of quick-installation structures, and in particular to a quick-installation structure and method for a switch. Background Art

[0002] A power tool is a tool that is actuated by an additional power source and mechanism other than manual labor alone with the use of a hand tool. The most common types of power tools use electric motors. Internal combustion engines and compressed air are also commonly used. Other power sources include steam engines, direct combustion of fuel and propellant, such as gunpowder-driven tools, and even natural power sources, such as wind or moving water.

[0003] An electric tool generally includes a head housing and a body housing, and a motor is provided in the body housing to drive the head housing. In order to save costs, relevant personnel designed a detachable connection between the head housing and the body housing, that is, a quick-install structure is adopted between the head housing and the body housing, and users can install different heads on the body according to work needs, without having to purchase multiple electric tools with different functions, thus saving purchase costs.

[0004] At present, the commonly used quick-installation structure includes setting a head-changing lock ring on the machine body, inserting the machine head into the head-changing lock ring, rotating the machine head, so that the locking block on the machine head is locked with the transverse slot on the head-changing lock ring to complete the installation. When the machine head is fixed in the above manner, there is a gap between the locking block and the transverse slot, and the gap gradually increases as the tool is used, which affects the normal use of the tool, so it needs to be improved. Summary of the invention

[0005] In order to improve the quick-install structure in the related art, the present application provides a quick-install structure and method for a switch.

[0006] The present application provides a switch quick-installation structure and method using the following technical solutions:

[0007] A quick-install structure for a switch comprises a replacement part and a connecting part, wherein the replacement part is arranged on the connecting part, a connecting groove is provided on the connecting part, a fixed head is provided on the replacement part, and the fixed head is inserted into the connecting groove, a first sleeve is sleeved on the replacement part, a limiting rubber ring is fixedly connected to the replacement part, the limiting rubber ring abuts against the inner side wall of the first sleeve, a second sleeve is provided at one end of the first sleeve away from the replacement part, the connecting part is inserted in the second sleeve, a tooth pattern is provided on the side wall of the connecting part for meshing with the inner side wall of the second sleeve, and when the second sleeve rotates on the replacement part, the inner side wall of the first sleeve is interference-fitted with the limiting rubber ring.

[0008] By adopting the above technical scheme, when the quick-release structure of the switch in the present application is used to complete the installation of the fixing part and the connecting part, the operator can first insert the fixing head into the connecting groove, and then rotate the second sleeve to make the second sleeve drive the first sleeve to rotate, so that the second sleeve moves in the direction away from the connecting part until the inner wall of the first sleeve and the limiting rubber ring are interfered with, thereby completing the quick release of the replacement part and the connecting part. The quick-release structure in the present application uses the interference setting of the limiting rubber ring and the inner wall of the second sleeve to achieve quick release of the replacement part. Compared with the quick-release method in the related art, it reduces the possibility of gaps affecting normal use after long-term use, thereby extending the service life.

[0009] Optionally, a limiting groove is provided on the inner side wall of the first sleeve, the inner side wall of the limiting groove is interference fit with the limiting rubber ring, and abutment teeth are provided on the inner side wall of the limiting groove.

[0010] By adopting the above technical solution, when the inner side wall of the first sleeve and the limiting rubber ring are in interference fit, the limiting rubber ring can be inserted into the limiting groove, and the friction between the limiting rubber ring and the inner side wall of the limiting groove can be increased by the structure of the abutment teeth. Compared with the limiting rubber ring directly abutting against the smooth side wall, the structure of the limiting groove and the abutment teeth further increases the stability of the interference fit between the first sleeve and the limiting rubber ring.

[0011] Optionally, the fixing head is a rectangular parallelepiped structure, and the fixing body is adapted to fit the connecting groove.

[0012] By adopting the above technical solution, since the connecting part is often a rapidly rotating motor structure when in use, the rectangular structure can enable the fixed head to be inserted into the connecting groove. As the motor rotates rapidly, the side walls of the rectangular structure can support the rotating part, thereby reducing the possibility of the fixed head slipping in the connecting groove as the motor rotates, resulting in a decrease in transmission efficiency.

[0013] Optionally, a first stabilizing magnet is disposed at one end of the fixing head close to the connecting portion, and a second stabilizing magnet is disposed at the bottom of the connecting groove, and the first stabilizing magnet and the second stabilizing magnet are magnetically attracted to each other.

[0014] By adopting the above technical solution, the structure of the first stabilizing magnet and the second stabilizing magnet, on the one hand, improves the convenience of inserting the fixed head into the connecting groove, and on the other hand, further reduces the possibility of the fixed head slipping in the connecting groove as the motor rotates, resulting in reduced transmission efficiency.

[0015] Optionally, the opening width of the end of the first sleeve close to the second sleeve is greater than the opening width of the end of the first sleeve away from the second sleeve.

[0016] By adopting the above technical solution, the opening width of the second sleeve gradually decreases from the end close to the first sleeve to the end away from the first sleeve, so that when the first sleeve does not have an interference fit with the limiting rubber ring, the first sleeve and the second sleeve can slide, thereby facilitating the operator to insert the connecting head through the second sleeve into the connecting groove, thereby improving the convenience of the operator during quick installation.

[0017] Optionally, the opening width of the opening at one end of the first sleeve close to the second sleeve is greater than the diameter of the limiting rubber ring.

[0018] By adopting the above technical solution, the opening width of the opening at one end of the first sleeve close to the second sleeve is greater than the diameter of the limiting rubber ring, so that when the operator moves the first sleeve and the second sleeve, it is not easy for the inner diameter of the first sleeve and the second sleeve to be too narrow and thus produce friction with the side wall of the limiting rubber ring, thereby improving the convenience of the operator when quickly installing the connecting part and the replacement part.

[0019] Optionally, the opening width of the opening at one end of the first sleeve away from the second sleeve is smaller than the maximum compression diameter of the limiting rubber ring, and the maximum compression diameter is the difference between the diameter of the limiting rubber ring and the maximum compression width of the limiting rubber ring.

[0020] By adopting the above technical solution, the opening width of the end of the first sleeve away from the second sleeve is smaller than the maximum compression diameter of the rubber ring, so that when the rubber ring abuts against the inner wall of the first sleeve and the rubber limiting ring is deformed, the first sleeve and the second sleeve are not easy to fall off the rubber ring, thereby increasing the stability of the quick-release structure in the present application when in use.

[0021] Optionally, a first stabilizing groove is provided on the side wall of the connecting portion, a second stabilizing groove is provided on the inner side wall of the stabilizing groove, the first stabilizing groove is connected to the second stabilizing groove, the limiting rubber ring is inserted in the first stabilizing groove, the limiting rubber ring is inserted in the second stabilizing groove, the limiting rubber ring is fixedly connected to the inner bottom wall of the first stabilizing groove, and the limiting rubber ring is fixedly connected to the inner bottom wall of the second stabilizing groove.

[0022] By adopting the above technical solution, the structure of the first stable groove and the second stable groove makes it difficult for the limiting rubber ring to fall off when connected to the connecting part, thereby increasing the stability of the limiting rubber ring when connected to the connecting part, thereby further improving the overall stability of the system and increasing the service life of the system.

[0023] Optionally, the limiting rubber ring is in interference fit with the first stable groove, and the limiting rubber ring is in interference fit with the second stable groove.

[0024] By adopting the above technical solution and a mechanism in which the limiting rubber ring is interference-fitted with the first stable groove and the second stable groove, the possibility of the limiting rubber ring moving or having gaps in the first stable groove and the second stable groove, which may cause the device using the quick-release structure in the present application to shake during use or the quick-release connection to loosen, is reduced.

[0025] Optionally, a quick installation method of a switch includes:

[0026] Determine the model of the replacement part according to the scenario to be used;

[0027] Rotate the first sleeve to separate the first sleeve from the limiting rubber ring;

[0028] Pass the replacement part to be used through the second sleeve, and insert the fixed head into the connection groove;

[0029] The first sleeve is rotated so that the rubber ring abuts against the first sleeve to complete the installation.

[0030] By adopting the above technical scheme, when the quick-installation structure of the switch in the present application is used to complete the installation of the fixing part and the connecting part, the operator can first rotate the first sleeve to move the first sleeve in a direction away from the replacement part to take out the original replacement part, and then pass the fixing head of the replacement part to be used through the second sleeve and insert it into the connecting groove, and the second sleeve is rotated to drive the first sleeve to rotate, so that the second sleeve moves in a direction away from the connecting part until the inner side wall of the first sleeve and the limiting rubber ring are interfered with, thereby completing the quick installation of the replacement part and the connecting part. The quick-installation structure in the present application adopts the interference setting of the limiting rubber ring and the inner side wall of the second sleeve to realize the quick installation of the replacement part. Compared with the quick installation method in the related art, the possibility of gaps affecting normal use after long-term use is reduced, thereby extending the service life.

[0031] In summary, the present application includes at least one of the following beneficial effects:

[0032] 1. The structure of the first sleeve and the limiting rubber ring is adopted. When the quick-installation structure of the switch in the present application completes the installation of the fixed part and the connecting part, the operator can first insert the fixed head into the connecting groove, and then rotate the second sleeve so that the second sleeve drives the first sleeve to rotate, so that the second sleeve moves in the direction away from the connecting part until the inner side wall of the first sleeve and the limiting rubber ring are interfered with, thereby completing the quick installation of the replacement part and the connecting part. The quick-installation structure in the present application adopts the interference setting method of the limiting rubber ring and the inner side wall of the second sleeve to realize the quick installation of the replacement part. Compared with the quick installation method in the related art, it reduces the possibility of gaps affecting normal use after long-term use, and prolongs the service life;

[0033] 2. The structure of the limiting groove and the abutting teeth is adopted. When the inner side wall of the first sleeve and the limiting rubber ring are in interference fit, the limiting rubber ring can be inserted into the limiting groove, and the friction between the limiting rubber ring and the inner side wall of the limiting groove can be increased by the structure of the abutting teeth. Compared with the limiting rubber ring directly abutting against the smooth side wall, the structure of the limiting groove and the abutting teeth further increases the stability of the interference fit between the first sleeve and the limiting rubber ring;

[0034] 3. The structure of the first stable groove and the second stable groove is adopted. The structure of the first stable groove and the second stable groove makes it difficult for the limiting rubber ring to fall off when connected to the connecting part, which increases the stability of the limiting rubber ring when connected to the connecting part, thereby further improving the overall stability of the system and increasing the service life of the system.

DETAILED DESCRIPTION

[0040] The following is combined with Figure 1-4 This application is described in further detail.

[0041] The present application discloses a quick-install structure and method for a switch. Figure 1 and Figure 2The quick-release structure of the switch is generally used in multi-head power tools. The quick-release structure of the switch generally includes a connecting part 12 and a replacement part 11. In the multi-head power tool, the connecting part 12 is a hand-held part, and a motor is arranged inside to drive the replacement part 11 to rotate. The replacement part 11 is various types of joints, which can realize multiple functions through the drive of the connecting part 12. For example, when the replacement part 11 is a screwdriver, the screw can be quickly loaded and unloaded; when the replacement part 11 is a stirrer, the liquid can be quickly stirred.

[0042] Reference Figure 3 and Figure 4 The end of the connecting part 12 close to the replacement part 11 is a cylindrical structure, and a connecting groove 13 is opened on the end of the connecting part 12 close to the replacement part 11. The connecting groove 13 is a non-circular groove (the connecting groove 13 can be a rectangular groove, a pentagonal groove, etc.). A fixing head 14 is welded and fixed on the end of the replacement part 11 close to the connecting groove 13. The fixing head 14 is adapted to the connecting groove 13, and a first stabilizing magnet 31 is glued and fixed on the end of the fixing head 14 close to the connecting groove 13. A second stabilizing magnet 32 ​​is glued and fixed on the bottom wall of the connecting groove 13 opposite to the fixing head 14. The first stabilizing magnet 31 and the second stabilizing magnet 32 ​​are magnetically attracted to each other, thereby improving the stability of the fixing head 14 inserted in the connecting groove 13, and then improving the stability of the connection between the replacement part 11 and the connecting part 12.

[0043] Reference Figure 3 and Figure 4 A first stable groove 41 is provided on the outer wall of the connecting portion 12, and the first stable groove 41 is a rectangular parallelepiped groove. A second stable groove 42 is provided on the inner wall of the first stable groove 41, and the second stable groove 42 is a rectangular parallelepiped groove, and the second stable groove 42 is connected to the first stable groove 41. A limiting rubber ring 17 is inserted into the first stable groove 41, and the limiting rubber ring 17 has an interference fit with the first stable groove 41 and the second stable groove 42 due to the effect of deformation. The limiting rubber ring 17 is glued and fixed to the bottom wall of the first stable groove 41, and the annular width of the limiting rubber ring 17 is greater than the depth of the first stable groove 41, and the portion of the limiting rubber ring 17 extending out of the first stable groove 41 is annular.

[0044] Reference Figure 3 and Figure 4, the replacement part 11 and the connecting part 12 are sleeved with a first sleeve 15, and the end wall of the first sleeve 15 is connected with a second sleeve 16. The first sleeve 15 is arranged at one end close to the connecting part 12, and the inner side wall of the first sleeve 15 is a curved surface. The opening width of the first sleeve 15 gradually increases along the direction toward the second sleeve 16 (the opening width in this application is the distance between the side wall of the first sleeve 15 and the outer side wall of the connecting part 12). The end of the first sleeve 15 close to the second sleeve 16 is the maximum opening width of the first sleeve 15, and its opening width is greater than the ring width of the limiting rubber ring 17; the end of the first sleeve 15 away from the second sleeve 16 is the minimum opening width of the first sleeve 15, and its opening width is less than the maximum compression diameter of the limiting rubber ring 17. The maximum compression diameter is the difference between the original width of the rubber ring and the maximum compression width of the limiting rubber ring 17. The maximum compression width of the limiting rubber ring 17 is the product of the original width of the rubber ring and the maximum compression rate of the rubber ring. For example, if the ring width of the limiting rubber ring 17 is 5 cm, since the maximum compression rate of the rubber is 50%, the maximum compression diameter of the limiting rubber ring 17 is 5-5*50%=2.5 cm, that is, the opening width of the end of the first sleeve 15 away from the second sleeve 16 is less than 2.5 cm.

[0045] Reference Figure 3 and Figure 4 A limiting groove 2 is provided on the inner side wall of the first sleeve 15, a limiting rubber ring 17 is inserted in the limiting groove 2, and the limiting rubber ring 17 abuts against the bottom wall of the inner side wall of the limiting groove 2, the limiting rubber ring 17 and the limiting groove 2 are interference fit, and abutting teeth 21 are provided on the inner side wall of the limiting groove 2 to increase the friction between the limiting rubber ring 17 and the side wall of the limiting groove 2, thereby increasing the stability of the interference fit between the limiting rubber ring 17 and the limiting groove 2.

[0046] Reference Figure 3 and Figure 4 An external thread structure is provided on the side wall of the replacement part 11, and a thread structure meshing with the external thread is provided on the inner wall of the second sleeve 16. Therefore, the second sleeve 16 can be moved in a direction away from the connecting part 12 by rotating the second sleeve 16, so that the second sleeve 16 drives the first sleeve 15 to move in a direction away from the connecting part 12. As the opening width of the first sleeve 15 gradually increases, the distance between the inner side wall of the first sleeve 15 and the limiting rubber ring 17 gradually decreases until the first sleeve 15 and the limiting rubber ring 17 are interference fit.

[0047] The implementation principle of a quick-installation structure and method of a switch in an embodiment of the present application is as follows: when the quick-installation structure of the switch in the present application is used to complete the installation of the fixing part and the connecting part 12, the operator can first rotate the first sleeve 15 to move the first sleeve 15 in a direction away from the replacement part 11 to take out the original replacement part 11, and then pass the fixing head 14 of the replacement part 11 to be used through the second sleeve 16 and insert it into the connecting groove 13, and rotate the second sleeve 16 to drive the first sleeve 15 to rotate, so that the second sleeve 16 moves in a direction away from the connecting part 12, until the inner side wall of the first sleeve 15 is interfered with the limiting rubber ring 17, thereby completing the quick installation of the replacement part 11 and the connecting part 12.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
