[0045] See also Figure 1-Figure 10 , which shows a schematic diagram of the structure of an embodiment of an expansion type door panel map pocket hole hemming device of the present invention, please refer to Figure 1-Figure 10, a detailed introduction is given to an expanding door panel map pocket hole edging device.

[0046] Example 1

[0047] An expansion type door panel map pocket hole edging device comprises a housing 100, wherein the housing 100 comprises a fixed frame 101 and an adjustment frame 102 symmetrically slidably located at the upper and lower sides of the fixed frame 101; a handle 106 is arranged on the top of the housing 100, and an anti-slip pattern 107 is arranged at the grip of the handle 106;

[0048] The handle 106 is provided to facilitate the user to hold the device and put it into the inner side of the map pocket hole, and the anti-slip pattern 107 increases the friction between the handle 106 and the user's palm, thereby improving the stability of the user's hand.

[0049] Two "U"-shaped movable frames 200 that move toward each other are respectively arranged on the left and right sides of each adjusting frame 102. A rotating rod 201 is arranged through the rear side wall of the movable frame 200 through the rotation of the bearing sleeve. The shaft gap of the rotating rod 201 passes through the rear side wall of the housing 100 and is fixedly connected to the input end of the universal joint 202. Through holes are opened symmetrically on the left and right sides of the rear side wall of the inner cavity of each adjusting frame. The four through holes are respectively provided for the four rotating rods to pass through and move laterally. The output end sliding sleeve of the universal joint 202 is provided with a first spline sleeve 203. The other end of the first spline sleeve 203 is fixedly provided with a mounting member 204. The mounting member 204 is detachably provided with a tap 205 and a screwdriver bit 206.

[0050] A rectangular mounting groove 207 is formed on one side of the mounting member 204 away from the first spline sleeve 203, and mounting blocks 208 are protruding from the ends of the tap 205 and the bit 206 and are inserted into the mounting groove 207;

[0051] The side wall of the mounting member 204 is threadedly provided with a bolt 209, and the end of the bolt 209 is provided with an adaptable nut 210. The side wall of the mounting block 208 is provided with a screw hole 211 for the bolt 209 to thread through.

[0052] According to the requirements, when it is necessary to drill and tap the inside of the map pocket hole, the tap 205 is installed on the mounting member 204, and when it is necessary to screw the screw, the screw head 206 is installed on the mounting member 204, wherein the inside of the hole of the screw head 206 is provided with a magnetic adsorption sheet, and the screws can be adsorbed one by one on the inside of the hole of the screw head 206, and then the device and all the screws are aligned with the previously opened screw holes, and then all the mounting members 204 are controlled to rotate, and the screws are installed on the inside of the map pocket hole through the screw head 206;

[0053] The tap 205 may be a composite tap that has both the punching and tapping functions, that is, it can punch a hole inside the map pocket hole and also meet the tapping requirements;

[0054] A magnetic adsorption sheet is provided inside the hole of the bit 206. Alternatively, instead of using a compound tap to drill a hole and tap, a self-tapping screw can be directly attached to the inner side of the hole of the bit 206 by magnetic adsorption. The self-tapping screw can be directly installed inside the hole of the map bag without drilling a base hole and tapping. The user can use it according to the needs.

[0055] A spacing adjustment component 300 is disposed inside the housing 100 and is used to adjust the spacing between the two movable frames 200 inside each adjustment frame 102;

[0056] The driving mechanism 400 is disposed inside the housing 100 and is used to drive the four mounting members 204 to rotate simultaneously;

[0057] Example 2

[0058] On the basis of Example 1, an opening 103 is opened in the middle of the rear side wall of the fixed frame 101, and a slot 104 for sliding the fixed frame 101 is opened on the side of the upper and lower adjustment frames 102 close to the fixed frame 101, and a vertical first telescopic rod 105 is fixedly provided at the opening 103 between the upper and lower adjustment frames 102;

[0059] The first telescopic rod 105 can be an existing small electric telescopic rod, or other components with telescopic and fixing functions. After the first telescopic rod 105 is extended and retracted, the distance between the upper and lower adjustment frames 102 can be pushed, thereby adjusting the distance between the upper and lower rows of mounting members 204. It should be noted that when the first telescopic rod 105 adjusts the distance between the two adjustment frames 102 to the maximum, the fixing frame 101 is always located inside the card slot 104, so as to avoid the adjustment frame 102 and the fixing frame 101 from being separated, and ensure that the housing 100 is still a "whole";

[0060] Example 3

[0061] On the basis of Example 1, the output end of the universal joint 202 is a first spline rod 212, the inner side of the first spline sleeve 203 is a spline groove 213 adapted to the first spline rod 212, the outer side of the shaft of the rotating rod 201 and the outer side of the shaft of the first spline sleeve 203 are respectively rotatably provided with side plates 214 through bearing sleeves, the side plate 214 close to the movable frame 200 is fixedly connected to the side wall of the movable frame 200 through a connecting plate 216, and a second telescopic rod 215 is provided between the two side plates 214, and the two ends of the second telescopic rod 215 are respectively hinged to the side walls of the two side plates 214;

[0062] The second telescopic rod 215 can be an existing small electric telescopic rod, or other components with telescopic and fixing functions. When it is necessary to diagonally drill holes or insert screws, the second telescopic rod 215 can be extended and retracted to adjust the angles of the two side panels 214, that is, the angle of the mounting member 204 can be adjusted, thereby changing the angles when drilling holes or inserting screws.

[0063] Example 4

[0064] On the basis of Example 1, the spacing adjustment component 300 includes a transverse positive and negative threaded rod 301 rotatably arranged between the left and right side walls of the inner cavity of the adjustment frame 102 through a bearing seat, and a transverse limit slide bar 302 fixedly arranged between the left and right side walls of the inner cavity of the adjustment frame 102. The left and right sections of the positive and negative threaded rod 301 are respectively screwed and driven to penetrate the side walls of the two movable frames 200, and the rod body of the limit slide bar 302 slides through the side walls of the two movable frames 200 respectively;

[0065] One end of the positive and negative threaded rod 301 extends and rotates through the side wall of the adjustment frame 102 and is provided with a knob 303;

[0066] The knob 303 drives the positive and negative threaded rod 301 to rotate. Since the threads of the left and right sections of the knob 303 run in opposite directions, the two movable frames 200 move toward each other, that is, the left and right spacing of the mounting member 204 can be adjusted.

[0067] Example 5

[0068] On the basis of Example 4, the driving mechanism 400 includes a fixing frame 401 fixedly arranged in the middle of the inner front wall of the fixing frame 101, and a vertical rotating shaft 402 is rotatably penetrated through the upper and lower walls of the fixing frame 401 through a bearing sleeve, and a vertical second spline rod 403 is fixedly arranged at the upper and lower ends of the rotating shaft 402, respectively, and a second spline sleeve 404 adapted to the hollow core of the second spline rod 403 is slidably sleeved on the outer wall of the second spline rod 403;

[0069] The ends of the upper and lower second spline sleeves 404 away from the second spline rod 403 are rotatably arranged on the side walls of the two adjustment frames 102 through the bearing seat, and the bottom wall of the lower adjustment frame 102 is fixedly installed with a servo reduction motor 405, and the output shaft of the servo reduction motor 405 is connected to the end of the lower second spline sleeve 404 through a coupling;

[0070] The servo reduction motor 405 is started to drive the second spline sleeve 404 at the bottom to rotate. Since the second spline rod 403 and the second spline sleeve 404 can rotate and slide relative to each other, the second spline sleeve 404 at the top can be driven to rotate at the same time. Moreover, when the spacing between the upper and lower adjustment frames 102 is adjusted, the second spline sleeve 404 will also slide with the second spline rod 403, so that the spacing between the two second spline sleeves 404 can be adjusted and can rotate at the same time.

[0071] The driving mechanism 400 further includes a third spline rod 406 which is rotatably arranged between the left and right side walls of the inner cavity of the adjustment frame 102 through a bearing seat, a worm gear 407 is fixedly arranged in the middle of the rod body of the third spline rod 406, and a worm 408 which meshes with the worm gear 407 is arranged on the outer side of the second spline sleeve 404;

[0072] When the two second spline sleeves 404 rotate, the third spline rod 406 can be driven to rotate through the worm gear 407;

[0073] The side wall of the movable frame 200 is rotatably penetrated by a second hollow spline sleeve 409 through a bearing sleeve, the second spline sleeve 409 is adapted to be slidably sleeved on the outer side of the third spline rod 406, a first bevel gear 410 is fixedly arranged on the outer side of the second spline sleeve 409, and a second bevel gear 411 meshing with the first bevel gear 410 is fixedly arranged at the front end of the rotating rod 201;

[0074] Since the third spline rod 406 and the second spline sleeve 409 can rotate, they can also slide relative to each other, that is, when the spacing of the movable frame 200 is adjusted left and right, the second spline sleeve 409 slides along the rod body of the third spline rod 406, and when the third spline rod 406 rotates, it can also drive the second spline sleeve 409 to rotate, and then drive the rotating rod 201 to rotate through the first bevel gear 410 and the second bevel gear 411, and then drive the first spline sleeve 203 to rotate through the universal joint 202, that is, all the mounting parts 204 can be driven to rotate at the same time.

[0075] In the specific use process, the left-right and front-back spacing of the mounting member 204 is adjusted according to the needs, and the spacing between the upper and lower adjustment frames 102 can be pushed by the first telescopic rod 105 after extension, so as to adjust the spacing between the upper and lower rows of mounting members 204.

[0076] The knob 303 drives the positive and negative threaded rod 301 to rotate. Since the threads of the left and right sections of the knob 303 run in opposite directions, the two movable frames 200 move toward each other, that is, the left and right spacing of the mounting member 204 can be adjusted.

[0077] When it is necessary to drill holes obliquely or insert screws, the angles of the two side panels 214 can be adjusted by extending and retracting the second telescopic rod 215, that is, the angle of the mounting member 204 can be adjusted, thereby changing the angle when drilling holes or inserting screws;

[0078] According to the requirements, when it is necessary to drill and tap the inside of the map pocket hole, the tap 205 is installed on the mounting member 204, and when it is necessary to screw the screw, the screw head 206 is installed on the mounting member 204, wherein the inside of the hole of the screw head 206 is provided with a magnetic adsorption sheet, and the screws can be adsorbed one by one on the inside of the hole of the screw head 206, and then the device and all the screws are aligned with the screw holes opened before, and then all the mounting members 204 are controlled to rotate, and the screws are installed on the inside of the map pocket hole through the screw head 206;

[0079] When it is necessary to control the rotation of the four mounting parts 204 at the same time, the servo reduction motor 405 is started to drive the second spline sleeve 404 at the bottom to rotate. Since the second spline rod 403 and the second spline sleeve 404 can rotate and slide relative to each other, the second spline sleeve 404 at the top can be driven to rotate at the same time. Moreover, when the spacing between the upper and lower adjustment frames 102 is adjusted, the second spline sleeve 404 will also slide with the second spline rod 403, so that the spacing between the two second spline sleeves 404 can be adjusted and can rotate at the same time. When the two second spline sleeves 404 rotate, the worm gear 4 07 can drive the third spline rod 406 to rotate. Since the third spline rod 406 and the second spline sleeve 409 can rotate, the two can also slide relative to each other, that is, when the spacing of the movable frame 200 is adjusted, the second spline sleeve 409 slides along the rod body of the third spline rod 406, and when the third spline rod 406 rotates, it can also drive the second spline sleeve 409 to rotate, and then the rotating rod 201 can be driven to rotate through the first bevel gear 410 and the second bevel gear 411, and then the first spline sleeve 203 can be driven to rotate through the universal joint 202, that is, all the mounting parts 204 can be driven to rotate at the same time.

[0080] After the screws are installed on the mounting member 204 through a screwdriver, the screws can be driven into the decorative fabric, making it more stable with the inner surface of the map pocket opening, thereby facilitating the hemming and reducing the shedding of the decorative fabric at a later stage.
