The present application is provided with a movable fixture that can facilitate the fixing of the mobile phone shell, facilitate the removal of the mobile phone shell during use, avoid damage to the surface of the mobile phone shell, improve the convenience of coating the mobile phone shell, and can adapt to the fixing of mobile phone shells of different sizes, facilitate operation, improve the practicality of the fixture, and avoid the problem of falling off when clamping the mobile phone shell; the present application is provided with a cover plate that can be fitted with the mounting plate, so that the atomized liquid during vacuum coating can effectively adhere to the surface of the mobile phone shell, improve the uniformity of the mobile phone shell coating, and improve the coating efficiency.

[0004] The above patent provides a fixed tube for the liquid inlet operation of the atomized liquid required for coating, but the fixed tube is directly exposed to the outside. When not in use, dust and other impurities in the external environment adhere to the inner wall of the fixed tube, which can easily cause the coating atomized liquid subsequently input into the fixed tube to be contaminated, affecting the subsequent coating effect; in addition, the mounting plate and the cover plate are placed separately. When the electronic device casing is subsequently coated, it is necessary to use external tools to seal the mounting plate and the cover plate, which is cumbersome and affects the processing efficiency. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a clamp for vacuum coating of electronic equipment housing, which has the characteristics of shielding dust and mobile connection.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a fixture for vacuum coating of electronic equipment housing, comprising a mounting plate, a clamping mechanism is arranged inside the mounting plate, a cover plate is arranged on one side of the mounting plate, a movable connecting component is arranged between the cover plate and the mounting plate, a fixed tube is connected to the side of the cover plate away from the mounting plate, and a shielding component is arranged at one end of the fixed tube.

[0007] Preferably, the shielding assembly includes an abutment, a connecting hinge, a shielding box and an external frame. The external frame is connected to the outer wall of one end of the fixed tube, a shielding box is provided on one side of the external frame, a connecting hinge is connected between the shielding box and the external frame, and an abutment is provided on the side wall of the cover plate and above the fixed tube.

[0008] Preferably, the abutment member includes an abutment rod, a cavity, a first spring, a sleeve plate and an abutment block.

The abutment block is connected to the sleeve plate at one end close to the abutment rod. A cavity is provided on the inner side wall of the abutment rod and at a position corresponding to the sleeve plate. The first spring is connected between the cavity and the sleeve plate.

[0009] Preferably, a guide post is connected to the interior of the cavity, and a guide hole is provided on the sleeve plate at a position corresponding to the guide post.

[0010] Preferably, the movable connection assembly includes an L-shaped plate, a threaded column, a connecting block, a threaded sleeve and an end plate, the L-shaped plate is connected to the side of the mounting plate away from the cover plate, one end of the L-shaped plate is connected to the end plate, a threaded column is connected between the L-shaped plate and the end plate, one end of the cover plate is connected to the connecting block located on the periphery of the threaded column, and a threaded sleeve is connected on the outer wall of the threaded column and located on one side of the connecting block.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model provides a shielding component. After the coating is completed, the abutment block is moved upward. The movement of the abutment block drives the sleeve plate to move inside the cavity. The sleeve plate moves and squeezes the first spring. When the abutment block is moved and retracted into the abutment rod, the shielding box loses the external supporting force. Then, the shielding box is rotated under the action of the connecting hinge so that the shielding box rotates and fits onto the side wall of the external frame. Under the action of the shielding box and the external frame, the fixed tube can be shielded and dust-proofed to prevent dust and other impurities in the external environment from adhering to the inside of the fixed tube, causing the internal environment of the fixed tube to be polluted, so that the atomized liquid required for subsequent coating inside the fixed tube is contaminated, affecting the subsequent coating quality of the electronic device casing.

[0014] 2. The utility model sets a movable connecting component, and the threaded sleeve is rotated to rotate and move along the threaded column. The movement of the threaded sleeve drives the connecting block to move, and the movement of the connecting block drives the cover plate and the reset slider to move. The movement of the reset slider drives the reset spring to stretch. When the cover plate moves to fit the side wall of the mounting plate, the threaded sleeve is stopped. After the subsequent electronic equipment casing is coated, the threaded sleeve is rotated again to rotate and move along the threaded column away from the connecting block. The reset spring loses the external force and returns to its original appearance, driving the connecting block to move, and then the cover plate can be driven to move away from the mounting plate, making it easy to remove the electronic equipment casing with the coating completed inside the clamping mechanism.

[0020] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a fixture for vacuum coating of an electronic device housing, comprising a mounting plate 2, a clamping mechanism 4 is arranged inside the mounting plate 2, a cover plate 1 is arranged on one side of the mounting plate 2, a movable connecting component 3 is arranged between the cover plate 1 and the mounting plate 2, a fixing tube 5 is connected to the side of the cover plate 1 away from the mounting plate 2, and a shielding component 6 is arranged at one end of the fixing tube 5.

[0023] Specifically, the shielding assembly 6 includes an abutment 61, a connecting hinge 62, a shielding box 63 and an external frame 64. The external frame 64 is connected to the outer wall of one end of the fixed tube 5. A shielding box 63 is provided on one side of the external frame 64. A connecting hinge 62 is connected between the shielding box 63 and the external frame 64. An abutment 61 is provided on the side wall of the cover plate 1 and above the fixed tube 5.

[0024] By adopting the above technical solution, when the fixed tube 5 needs to be used, the shielding box 63 is first rotated under the action of the connecting hinge 62. When the shielding box 63 is rotated to one end of the external frame 64, the abutment 61 is used to abut the shielding box 63, and then the fixed tube 5 is used to ensure the normal use of the fixed tube 5. After the fixed tube 5 is used, the abutment effect of the abutment 61 on the shielding box 63 is released, and then the shielding box 63 is rotated under the action of the connecting hinge 62, so that the shielding box 63 is rotated to fit the side wall of the external frame 64. Under the action of the shielding box 63 and the external frame 64, the fixed tube 5 can be shielded and dust-proofed to prevent dust and other impurities in the external environment from adhering to the inside of the fixed tube 5, causing the internal environment of the fixed tube 5 to be polluted.

[0025] Specifically, the abutment 61 includes an abutment rod 611, a cavity 612, a first spring 613, a sleeve plate 614 and an abutment block 615. The abutment rod 611 is connected to the side wall of the cover plate 1 and is located above the fixed tube 5. An abutment block 615 is provided on one side of the abutment rod 611. An end of the abutment block 615 close to the abutment rod 611 is connected to the sleeve plate 614. A cavity 612 is provided on the inner side wall of the abutment rod 611 at a position corresponding to the sleeve plate 614. The first spring 613 is connected between the cavity 612 and the sleeve plate 614.

[0026] By adopting the above technical solution, when the shielding box 63 needs to be rotated, the abutment block 615 is moved upward, and the movement of the abutment block 615 drives the sleeve 614 to move inside the cavity 612. The sleeve 614 moves to squeeze the first spring 613. When the abutment block 615 moves and is retracted into the abutment rod 611, the movement of the abutment block 615 is stopped to prevent the abutment block 615 from affecting the rotation operation of the shielding box 63.

[0027] Specifically, the interior of the cavity 612 is connected to a guide post, and a guide hole is provided on the sleeve 614 at a position corresponding to the guide post.

[0028] By adopting the above technical solution, during the movement of the sleeve plate 614, the cooperation of the guide pillars and the guide holes can provide a guiding effect for the movement of the sleeve plate 614, thereby improving the stability of the movement of the sleeve plate 614.

[0029] When the present embodiment is used, the electronic device housing is placed inside the mounting plate 2, and the clamping mechanism 4 is used to clamp the electronic device housing, and then the cover plate 1 is moved and fitted onto the side wall of the mounting plate 2 by the movable connecting assembly 3, and then the abutment block 615 is moved upward, and the abutment block 615 moves to drive the sleeve plate 614 to move inside the cavity 612, and the sleeve plate 614 moves to squeeze the first spring 613. When the abutment block 615 is moved and retracted into the abutment rod 611, the shielding box 63 is rotated under the action of the connecting hinge 62. When the shielding box 63 is rotated to one end of the external frame 64, the abutment block 615 is released, and the first spring 613 loses the external force and returns to its original state, driving the sleeve plate 614 to move inside the cavity 612, and the sleeve plate 614 moves to drive the abutment block 615 to move. Under the action of the abutment block 615, the shielding box 63 can be abutted and fixed, and then the fixing tube 5 is fixed. After the coating is completed, the abutment block 615 is moved upward, and the abutment block 615 moves to drive the sleeve plate 614 to move inside the cavity 612, and the sleeve plate 614 moves to squeeze the first spring 613. When the abutment block 615 is moved and retracted into the abutment rod 611, the shielding box 63 loses the external supporting force. Then, under the action of the connecting hinge 62, the shielding box 63 is rotated so that the shielding box 63 is rotated to fit the side wall of the external frame 64. Under the action of the shielding box 63 and the external frame 64, the fixed tube 5 can be shielded and dust-proofed to prevent dust and other impurities in the external environment from adhering to the inside of the fixed tube 5, causing the internal environment of the fixed tube 5 to be polluted, so that the atomized liquid required for the subsequent coating inside the fixed tube 5 is contaminated, affecting the subsequent coating quality of the electronic device housing;

[0030] Example 2

[0031] The present embodiment differs from the first embodiment in that the movable connection assembly 3 includes an L-shaped plate 31, a threaded column 32, a connecting block 33, a threaded sleeve 34, and an end plate 35. The L-shaped plate 31 is connected to the side of the mounting plate 2 away from the cover plate 1. One end of the L-shaped plate 31 is connected to the end plate 35. The threaded column 32 is connected between the L-shaped plate 31 and the end plate 35. The connecting block 33 is connected to one end of the cover plate 1 and is located on the periphery of the threaded column 32. The threaded sleeve 34 is connected to the outer wall of the threaded column 32 and is located on one side of the connecting block 33.

[0032] Specifically, the end of the connecting block 33 away from the cover plate 1 is connected to a reset slider, and a reset slot is provided on the inner side wall of the L-shaped plate 31 at the position corresponding to the reset slider, and a reset spring is connected between the reset slider and the reset slot.

[0033] By adopting the above technical solution, the connection block 33 moves and drives the reset slider to move inside the reset slot, and the movement of the reset slider drives the reset spring to stretch. After the threaded sleeve 34 is subsequently rotated to move it away from the connection block 33, the reset spring loses the external force and returns to its original state, driving the reset slider to move inside the reset slot, and the reset slider drives the connection block 33 to move, thereby driving the cover plate 1 to move, thereby facilitating the reset operation of the cover plate 1.

[0034] When this embodiment is in use, the threaded sleeve 34 is rotated to rotate and move along the threaded column 32. The movement of the threaded sleeve 34 drives the connecting block 33 to move. The movement of the connecting block 33 drives the cover plate 1 and the reset slider to move. The movement of the reset slider drives the reset spring to stretch. When the cover plate 1 moves to fit the side wall of the mounting plate 2, the rotation of the threaded sleeve 34 is stopped. After the subsequent electronic device shell is coated, the threaded sleeve 34 is rotated again to rotate and move along the threaded column 32 away from the connecting block 33. The reset spring loses the external force and returns to its original state, driving the connecting block 33 to move, and then driving the cover plate 1 to move away from the mounting plate 2, making it easy to remove the electronic device shell with the coating completed inside the clamping mechanism 4.

[0035] The structure and principle of the clamping mechanism 4 composed of a clamp, a slide groove, a spring and a slider in this utility model have been disclosed in a fixing clamp for coating of a mobile phone shell disclosed in Chinese patent application No. 202121614947.3. Its working principle is: a slide groove is provided on the surface of the mounting plate 2, and a spring is fixedly connected to the inside of the slide groove. The inside of the slide groove is slidably connected to the slider, and the slider contacts the end of the spring. A clamp is connected to the side wall of the slider. When in use, the clamp is installed on the surface of the mounting plate 2 through the slider, and the slider is inserted into the inside of the slide groove to realize the installation of the clamp. After the clamp is installed, the clamp is moved to drive the slider to contact the spring. After the spring is compressed, the electronic device shell is placed between the clamps to realize the clamping of the electronic device shell. The elasticity of the spring pushes the clamp to improve the stability of the electronic device shell when it is fixed to avoid falling off.

[0036] The working principle and use process of the present invention are as follows: the present invention places the electronic device housing inside the mounting plate 2, and uses the clamping mechanism 4 to clamp the electronic device housing, and then uses the mobile connecting component 3 to drive the cover plate 1 to move and fit onto the side wall of the mounting plate 2, and then moves the abutment block 615 upward, and the abutment block 615 moves to drive the sleeve plate 614 to move inside the cavity 612, and the sleeve plate 614 moves to squeeze the first spring 613, and when the abutment block 615 moves and is retracted into the abutment rod 611, the shielding box 63 is rotated under the action of the connecting hinge 62, and when the shielding box 63 is rotated to the external frame 64 After one end, the abutment block 615 is released, and the first spring 613 loses the external force and returns to its original state, driving the sleeve 614 to move inside the cavity 612. The movement of the sleeve 614 drives the abutment block 615 to move. Under the action of the abutment block 615, the shielding box 63 can be abutted and fixed. Then the threaded sleeve 34 is rotated to rotate along the threaded column 32. The movement of the threaded sleeve 34 drives the connecting block 33 to move. The movement of the connecting block 33 drives the cover plate 1 and the reset slider to move. The movement of the reset slider drives the reset spring to stretch. When the cover plate 1 moves to fit the side wall of the mounting plate 2, the threaded sleeve 34 is stopped. Then, the atomized liquid required for vacuum coating is sprayed onto the electronic device housing inside the clamping mechanism 4 through the fixed tube 5, and the electronic device housing is subjected to coating operation. After the coating is completed, the abutment block 615 is moved upward, and the abutment block 615 moves to drive the sleeve plate 614 to move inside the cavity 612. The sleeve plate 614 moves to squeeze the first spring 613. When the abutment block 615 moves and is retracted into the abutment rod 611, the shielding box 63 loses the external supporting force. Then, the shielding box 63 is rotated under the action of the connecting hinge 62, so that the shielding box 63 rotates and fits onto the side wall of the external frame 64. 4, the fixed tube 5 can be shielded and dust-proofed to prevent dust and other impurities in the external environment from adhering to the inside of the fixed tube 5, causing the internal environment of the fixed tube 5 to be polluted, so that the atomized liquid required for subsequent coating inside the fixed tube 5 is contaminated, affecting the subsequent coating effect of the electronic device casing. Then, the threaded sleeve 34 is rotated to rotate along the threaded column 32 and move away from the connecting block 33. The reset spring loses the external force and returns to its original state, driving the connecting block 33 to move, and then the cover plate 1 can be driven to move away from the mounting plate 2, making it easy to take out the electronic device casing with the coating completed inside the clamping mechanism 4.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
