Description

Technical Field

[0001] This application relates to the field of sealing ring installation technology, and more particularly to a fixture. Background Technology

[0002] When assembling and repairing electronic products such as mobile phones, it is necessary to assemble the sealing rings for the buttons. Typically, the button sealing rings are installed manually, but the small size of the buttons makes them difficult to secure, increasing the difficulty of installation. Utility Model Content

[0003] In view of this, this application provides a fixture that can improve the installation difficulty of installing a sealing ring on a button.

[0004] This application provides a fixture for mounting a sealing ring on a button, comprising a housing, a positioning cover, and a pressing assembly. The housing has a receiving cavity, and the housing includes a first end and a second end disposed opposite to each other, the receiving cavity passing through the first end and the second end. The positioning cover is fixed to the first end of the housing. The pressing assembly is received within the receiving cavity, and the pressing assembly includes a pressing rod, an elastic element, and a fixing block. The pressing rod includes a pressing end that extends from the second end. The elastic element is sleeved on the pressing rod. The fixing block is fixed to the end of the pressing rod away from the pressing end. The fixing block is used for the sealing ring to be sleeved on its periphery. When the pressing end is pressed, the fixing block extends from the positioning cover until it abuts against the button, so that the user can push the sealing ring to the periphery of the button.

[0005] In some possible implementations, the positioning cover has a positioning groove, the positioning cover being fitted onto the button so that the button is accommodated within the positioning groove.

[0006] In some possible implementations, the positioning cover has opposing first and second plates, the first plate having a notch communicating with the end face of the positioning cover away from the first end.

[0007] In some possible implementations, a first elastic block is fitted onto the fixed block.

[0008] In some possible implementations, the pressing rod has a convex ring on its periphery, the convex ring being disposed between the pressing end and the fixing block, and a retaining ring is also protruding on the inner wall of the housing, the elastic element elastically abutting between the retaining ring and the convex ring.

[0009] In some possible implementations, the fixture further includes a stop block mounted on the second end, the stop block having a through hole through which the pressing rod passes, the stop block abutting against the convex ring, and the pressing end extending from the stop block.

[0010] In some possible implementations, the stop block includes a first block and a second block connected to the first block, the first block being installed in the receiving cavity, and the second block extending out of the second end and fixed to the housing.

[0011] In some possible implementations, the fixture further includes a stop fastener, by which the positioning cover is secured to the housing.

[0012] In some possible implementations, the fixture further includes a second elastic block fitted onto the positioning cover.

[0013] In some possible implementations, the second elastic block is made of urethane.

[0014] The fixture provided in this application allows for the installation of a sealing ring on a button. Pressing the pressing end causes a fixing block to extend from the positioning cover via a pressing rod, allowing the sealing ring to be fitted around the periphery of the fixing block. The fixing block is then moved above the button and pressed onto it, thus fixing the button below the fixing block. The user then slides the sealing ring onto the button, thus installing it. This process, by installing the sealing ring on the fixing block and then sliding it onto the button, improves the efficiency of installing the sealing ring on the button and is also beneficial for installing sealing rings on smaller buttons. It addresses the problem of buttons being difficult to fix when installing sealing rings. Furthermore, the fixture provided in this application has a simple structure, is easy to operate, and has strong versatility. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0028] To further illustrate the technical means and effects adopted by this application in achieving its intended purpose, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments.

[0029] Please see Figure 1 , Figure 2 and Figure 3 This application provides a fixture 100 for mounting a sealing ring 300 onto a button 200. The fixture 100 includes a housing 10, a positioning cover 20, and a pressing assembly 30. The housing 10 has a receiving cavity 13 and includes a first end 11 and a second end 12 disposed opposite to each other. The receiving cavity 13 passes through the first end 11 and the second end 12. Both ends of the first end 11 and the second end 12 have openings that communicate with the receiving cavity 13. The positioning cover 20 is fixed to the first end 11 of the housing 10. When the fixture 100 is facing the button 200, as... Figure 6 The button 200 can be housed within the positioning cover 20 to achieve alignment between the fixture 100 and the button 200.

[0030] Combination Figure 4 The pressing assembly 30 is housed within the receiving cavity 13. The pressing assembly 30 includes a pressing rod 31, an elastic element 33, and a fixing block 34. The pressing rod 31 includes a pressing end 311 extending from the second end 12. The elastic element 33 is sleeved on the pressing rod 31, and the fixing block 34 is fixed to the end of the pressing rod 31 away from the pressing end 311. The fixing block 34 is used for the sealing ring 300 to be sleeved around its periphery. When the pressing end 311 is pressed, such as… Figure 5 and Figure 7 The fixing block 34 extends from the positioning cover 20 until it abuts against the button 200, along the length of the pressing rod 31 so that the user can move the sealing ring 300 to the periphery of the button 200.

[0031] In the fixture 100 provided herein, when it is necessary to install the sealing ring 300 onto the button 200, pressing the pressing end 311 causes the fixing block 34 to extend from the positioning cover 20 via the pressing rod 31. The sealing ring 300 is fitted around the periphery of the fixing block 34. The fixing block 34 is moved above the button 200 and pressed onto the button 200, thereby fixing the button 200 below the fixing block 34. Then, the user or operator slides the sealing ring 300 onto the button 200, thus installing the sealing ring 300 onto the button 200. In this process, by installing the sealing ring 300 onto the fixing block 34 and then sliding it onto the button 200, the efficiency of installing the sealing ring 300 on the button 200 is improved. It also facilitates the installation of the sealing ring 300 on the smaller button 200, improving the problem of the button 200 being difficult to fix when installing the sealing ring 300. At the same time, the fixture 100 provided in this application has a simple structure, is easy to operate, and has strong versatility.

[0032] In some embodiments, button 200 can be a button 200 of an electronic device, such as a power button, volume button, etc. The electronic device can be a mobile phone, computer, tablet computer, camera, etc.

[0033] See Figure 3 and Figure 6 In some embodiments, the positioning cover 20 has a positioning groove 23, which is used to fit over the button 200 so that the button 200 is accommodated within the positioning groove 23. The general outline of the positioning cover 20 is a hollow square. The positioning groove 23 of the positioning cover 20 is adapted to the size of the button 200. The positioning cover 20 uses the positioning groove 23 to achieve accurate alignment between the fixing block 34 and the button 200 when the fixing block 34 is set on the button 200, so as to guide the alignment of the top surface of the fixing block 34 and the button 200, so as to facilitate the quick sliding of the sealing ring 300 onto the button 200.

[0034] In some embodiments, the surface of the fixing block 34 away from the pressing rod 31 is the same size as the top surface of the button 200, so that when the fixing block 34 is pressed onto the button 200, the fixing block 34 is facing the surface of the button 200, so that the sealing ring 300 can be quickly moved onto the button 200, thereby improving installation efficiency.

[0035] See Figure 2 In some embodiments, the button 200 is provided with a groove 210 for accommodating the sealing ring 300. The groove 210 is arranged in a ring on the outer wall of the button 200, so that the sealing ring 300 is embedded in the groove 210.

[0036] See Figure 4 In some embodiments, the positioning cover 20 has a first plate 21 and a second plate 22 facing each other. The first plate 21 has a notch 211 that communicates with the end face of the positioning cover 20 away from the first end 11. The notch 211 is provided to facilitate observation and confirmation of the protrusion of the fixing block 34 when the pressing rod 31 is pressed, and also to facilitate observation of the positioning cover 20 being fitted onto the button 200 when the fixing block 34 is on the button 200. In some embodiments, the notch 211 is located in the middle of the first plate 21 away from the button 200 rod to facilitate better observation of the installation.

[0037] In some embodiments, the second plate 22 is also provided with a notch 211 at the position corresponding to the first plate 21, and the two notches 211 are provided correspondingly.

[0038] See Figure 3 and Figure 4In some embodiments, a protruding ring 32 is provided around the periphery of the pressing rod 31, and the protruding ring 32 is disposed between the pressing end 311 and the fixing block 34. A retaining ring 14 is also provided on the inner wall of the housing 10, and an elastic member 33 elastically abuts against the retaining ring 14 and the protruding ring 32. So that when the pressing end 311 of the pressing rod 31 is not subjected to external force, the pressing rod 31 is reset under the action of the elastic member 33, and the fixing block 34 is placed in the positioning cover 20. In some embodiments, the retaining ring 14 is disposed around the inner wall of the receiving cavity 13, and the retaining ring 14 is disposed near the first end 11, thereby reducing the length of the housing 10 to optimize the structure of the fixture 100 and reduce the weight of the fixture 100.

[0039] See Figure 4 In some embodiments, a first elastic block 40 is fitted onto the fixing block 34. The first elastic block 40 is fitted onto the fixing block 34 to facilitate contact between the sealing ring 300 and the first elastic block 40, reducing wear on the sealing ring 300 caused by the fixing block 34 and protecting the surface of the sealing ring 300. In some embodiments, the first elastic block 40 may be made of urethane rubber. In some embodiments, the fixing block 34 includes a first block 341 and a second block 342 fixedly connected to the first block 341. The first block 341 is fixed to the pressing rod 31 by fasteners. The second block 342 has a generally square outline. The first elastic block 40 has a hollow structure and is fitted onto the second block 342. The shape of the first elastic block 40 is adapted to the shape of the second block 342. The first elastic block 40 is elastic, preventing wear on the sealing ring 300 during installation and protecting the appearance of the sealing ring 300.

[0040] See Figure 5 , Figure 6 and Figure 7 When the sealing ring 300 needs to be installed on the button 200, press the pressing end 311, the elastic element 33 is compressed, and the fixing block 34 extends out from the positioning cover 20 (e.g., Figure 5 Then, the sealing ring 300 is fitted onto the periphery of the fixing block 34, allowing it to be positioned close to the bottom of the fixing block 34. This facilitates quick transfer of the sealing ring 300 from the fixing block 34 to the button 200. Releasing the pressing end 311 causes the elastic element 33 to extend, the pressing rod 31 to reset, and pulls the fixing block 34 and the sealing ring 300 back into the positioning cover 20. Simultaneously, the fixture 100 is moved onto the button 200. Figure 6 This allows the positioning cover 20 to be placed on the button 200, and the size of the positioning groove 23 of the positioning cover 20 matches the shape of the button 200, achieving alignment between the fixing block 34 and the button 200. At this time, the fixing block 34 presses against the button 200. Figure 7Press the pressing end 311 again, causing the elastic element 33 to be compressed. The positioning cover 20 moves away from the button 200, exposing the button 200, the fixing block 34, and the sealing ring 300. Then, the sealing ring 300 on the fixing block 34 is moved towards the button 200 along the direction of the pressing rod 31, so that the sealing ring 300 is fitted onto the button 200, specifically within the groove 210 of the button 200, thus achieving the installation of the sealing ring 300. Then, remove the fixture 100 and fit another sealing ring 300 onto the fixing block 34, repeating this process to assemble multiple sealing rings 300.

[0041] See Figure 3 and Figure 4 In some embodiments, the fixture 100 further includes a stop block 60, which is mounted on the second end 12. The stop block 60 has a through hole 63 through which the pressing rod 31 passes. The stop block 60 abuts against the protruding ring 32, and the pressing end 311 extends out from the stop block 60. The stop block 60 is threaded into the housing 10, and one end of the stop block 60 abuts against the protruding ring 32, thereby installing the pressing rod 31 into the housing 10 and preventing the pressing rod 31 from disengaging from the housing 10 during the resetting process.

[0042] In some embodiments, the stop block 60 includes a first block 61 and a second block 62 connected to the first block 61. The first block 61 is installed within the receiving cavity 13, and the second block 62 extends out of the second end 12 and is fixed to the housing 10. The stop block 60 is installed within the housing 10 via the second block 62, thereby fixing the stop block 60 within the housing 10. The outer diameter of the first block 61 is smaller than the outer diameter of the second block 62. The first block 61 is positioned to abut against the protruding ring 32.

[0043] See Figure 3 and Figure 4 In some embodiments, the fixture 100 further includes a second elastic block 50, which is fitted onto the positioning cover 20. The shape of the second elastic block 50 is adapted to the shape of the positioning cover 20. The second elastic block 50, fitted onto the positioning cover 20, increases the elasticity of the positioning cover 20, thereby reducing scratches on the button 200 and protecting its appearance when the positioning cover 200 is placed over it. In some embodiments, the second elastic block 50 is made of urethane rubber.

[0044] See Figure 5 In some embodiments, the fixture 100 further includes a stop fastener 70, by which the positioning cover 20 is secured to the housing 10. The stop fastener 70 may be a screw to secure the positioning cover 20 to the housing 10.

[0045] The fixture 100 provided in this application, when it is necessary to install the sealing ring 300 on the button 200, presses the pressing end 311, and the pressing rod 31 drives the fixing block 34 to extend out of the positioning cover 20, so that the sealing ring 300 is sleeved on the periphery of the fixing block 34. The fixing block 34 is moved above the button 200 and pressed onto the button 200, thereby fixing the button 200 below the fixing block 34. Then the user pushes the sealing ring 300 onto the button 200, thereby installing the sealing ring 300 onto the button 200. In this process, by installing the sealing ring 300 onto the fixing block 34 and then pushing it onto the button 200, the efficiency of installing the sealing ring 300 on the button 200 is improved, and it is also beneficial to install the sealing ring 300 on the small button 200. It improves the problem that the button 200 is not easy to fix when installing the sealing ring 300. At the same time, the fixture 100 provided in this application has a simple structure, is easy to operate, and has strong versatility.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
