[0014] The drive plate is provided with a drive connecting plate, and the drive connecting plate is connected to the drive element. The platform is provided with a third guide groove.

[0015] The advantages and positive effects of this invention are as follows:

[0016] 1. This invention utilizes the rotation of the drive disc to drive the drive linkages on both sides to close and move, thereby driving the first pressing assembly and the second pressing assembly to close and move to press the doorpost onto the self-closing mechanism. This invention balances the forces on both sides of the self-closing mechanism, reducing the possibility of workpiece damage during pressing, and can also drive multiple pressing rods to move at one time, thereby simultaneously completing the pressing operation of multiple doorposts on both sides of the self-closing mechanism. It is simple to operate and improves work efficiency.

[0017] 2. The press head in the press assembly of this invention is designed specifically for the special structure of the doorpost. Considering that the doorpost and the self-closing mechanism are made of rubber, while the self-closing mechanism housing is made of plastic, and that an interference fit is required, the upper and lower outer plates of the doorpost are respectively positioned in the press grooves of the corresponding protrusions of the press head during press assembly. The first protrusion of the press head abuts against the first annular protrusion of the doorpost, and the second protrusion of the press head abuts against the second annular protrusion of the doorpost. Furthermore, the front ends of both protrusions of the press head form an arc surface with the same diameter φ as the annular protrusion of the doorpost to ensure... The invention ensures smooth pressing of the pressure head while preventing damage to components such as the doorpost. Furthermore, each pressure rod is secured to its corresponding pressing slide by locking bolts in a slotted clamp. This structure not only facilitates the replacement of pressure rods of appropriate specifications according to actual needs, but also allows for flexible adjustment of the pressure rod position and extension length. Fine-tuning the pressure rod position ensures that the upper and lower outer panels of the doorpost are accurately positioned in the pressure groove of the pressure head, while fine-tuning the pressure rod extension length ensures that the pressure rod movement pressure meets the pressing requirements while further preventing damage to components such as the doorpost.

[0018] 3. This invention requires that the centers of the pressure head, the door post, and the slots on the self-priming mechanism be aligned on the same straight line during press-fitting; otherwise, deviations will still damage the components. Therefore, this invention first ensures the linear drive of the pressure rod by using a linear sliding engagement between the drive linkage and the corresponding slide block, as well as an engagement with the arc-shaped drive groove on the drive disc. Secondly, the door post guide grooves on each guide block on the platform are designed specifically for the door post's unique structure. The door post guide groove includes an upper first groove and a lower second groove. The cover at the lower end of the door post is located in the first groove and moves along it, while the column head at the lower end of the door post is located in the second groove and moves within it. This invention further ensures accurate door post movement through the aforementioned cooperation between the pressure head and the door post guide groove structure, thereby guaranteeing accurate press-fitting.

The opening and closing movement of the driving linkages on both sides of the driving disk 603 drives the first pressing assembly 2 and the second pressing assembly 3 to open and close, and respectively press the corresponding doorposts 7 into the corresponding slots 501 on the self-closing mechanism 5.

[0035] like Figures 3 to 4 As shown, in this embodiment, the base plate 8 has a first slide block 608 at one end and a second slide block 607 at the other end. The first drive link 601 in the press-fit drive assembly 6 has a first slider on its lower side that slides in cooperation with a slide rail on the first slide block 608.

Figure 3 As shown, a bearing seat 604 is provided in the middle of the base plate 8, and a rotating shaft 605 is provided inside the bearing seat 604. The upper end of the rotating shaft 605 is fixedly connected to the drive disk 603.

[0036] like Figures 1 to 2 As shown, in this embodiment, the first pressing assembly 2 includes a first pressing slider 201 and a first pressing rod 202. The platform 1 is provided with a first guide block 101 and a first guide groove 105. The first pressing slider 201 passes through the first guide groove 105 and is connected to the first driving link 601 in the pressing drive assembly 6. The first pressing rod 202 is provided on the first pressing slider 201, and the front end of the first pressing rod 202 is provided with a first pressing head 203. The first guide block 101 is provided with a first door post guide groove. The door post 7 is provided in the first door post guide groove and is driven to be pressed into the slot 501 on the corresponding side of the self-priming mechanism 5 by the first pressing head 203.

[0037] like Figures 1 to 2As shown in this embodiment, the self-priming mechanism 5 has a slot 501 on the side near the first pressing assembly 2. The first pressing slider 201 is L-shaped, and the vertical part of the first pressing slider 201 passes through the first guide groove 105 and is connected to the first driving connecting rod 601. The horizontal part of the first pressing slider 201 has a first slot 2011, and the upper and lower sides of the slot 2011 are connected by the first locking bolt 2012. The rear end of the first pressing rod 202 is located in the first slot 2011, and the first slot 2011 is locked and clamped by the first locking bolt 2012. This structure facilitates the installation and replacement of the first pressing rod 202 of the appropriate specification. In addition, it also facilitates the adjustment of the position of the first pressing head 203 at the front end of the first pressing rod 202 and the distance between it and the corresponding door post 7. While ensuring the pressing pressure, it also minimizes damage to components such as the door post 7.

[0038] like Figures 1 to 2 As shown, in this embodiment, the second pressing assembly 3 includes a second pressing slider 301 and a second pressing rod 302. The platform 1 is provided with a second guide block 108 and a second guide groove 107. The lower end of the second pressing slider 301 passes through the second guide groove 107 and is connected to the second driving link 606 in the pressing drive assembly 6. The second pressing rod 302 is provided on the second pressing slider 301, and the front end of the second pressing rod 302 is provided with a second pressing head 303. The second guide block 108 is provided with a second door post guide groove. The door post 7 is provided in the second door post guide groove and is driven to be pressed into the slot 501 on the corresponding side of the self-priming mechanism 5 by the second pressing head 303.

[0039] like Figures 1 to 2 As shown, in this embodiment, the self-priming mechanism 5 has two slots 501 on the side near the second pressing assembly 3, such as... Figures 7 to 8 As shown, the lower end of the middle part of the second pressing slider 301 is provided with a connecting block 3014, and the lower end of the connecting block 3014 passes through the second guide groove 107 and is connected to the second driving link 606 in the pressing drive assembly 6. In addition, in this embodiment, the second pressing slider 301 is provided with second slots 3011 on both sides, and the upper and lower sides of the slots 3011 are connected by second locking bolts 3012. The rear end of the second pressing rod 302 is located in the corresponding second slot 3011, and the second slot 3011 is locked and clamped by the second locking bolts 3012. This structure facilitates the installation and replacement of the second pressing rod 302 of appropriate specifications. In addition, it also facilitates the adjustment of the position of the second pressing head 303 at the front end of the second pressing rod 302 and the distance between it and the corresponding door post 7, ensuring pressing while minimizing damage to the door post 7 and other components.

[0040] like Figures 7 to 13As shown, the doorpost 7 of this invention has a relatively special structure. The upper end of the doorpost 7 is provided with a cross portion 701, a first annular protrusion 702 and a second annular protrusion 703 from top to bottom. The cross portion 701 forms an upper outer side plate 7011 on the side away from the self-closing mechanism 5. A locking portion that cooperates with the slot 501 is formed between the first annular protrusion 702 and the second annular protrusion 703. A lower outer side plate 706 is provided on one side of the second annular protrusion 703, and the lower outer side plate 706 and the upper outer side plate 7011 are on the same plane. To ensure successful press-fitting, the first press head 203 and the second press head 303 of this invention have identical structures. Each has a first protrusion 3031 on its upper front side and a second protrusion 3032 on its lower front side. A through-groove 3033 is formed between the middle of the first protrusion 3031 and the middle of the second protrusion 3032. During press-fitting, the upper outer plate 7011 of the doorpost 7 is positioned in the groove 3033 of the first protrusion 3031. The first protrusion 3031 abuts against the first annular protrusion 702, and the second protrusion 3032 abuts against the second annular protrusion 703. The lower outer plate 706 of the doorpost 7 is positioned in the groove 3033 of the second protrusion 3032. After press-fitting, the engaging part engages with the slot 501. Figures 12 to 13 As shown, in order to ensure smooth pressing, the front end of the first protrusion 3031 and the front end of the second protrusion 3032 are both provided with an arc surface with the same diameter φ as the first annular protrusion 702 and the second annular protrusion 703. This can further avoid damaging the door post 7 and other components.

[0041] Other examples Figure 12 As shown, this invention requires that the centers of the pressure head, the door post 7, and the slots 501 on the self-priming mechanism 5 be on the same straight line during press-fitting; otherwise, deviations will still damage the components. Therefore, firstly... Figure 6 As shown, the two drive linkages in the press-fit drive assembly 6 of the present invention ensure the linear drive of the pressure rods on both sides of the self-priming mechanism 5 by linear sliding cooperation with the corresponding slide block and cooperation with the arc-shaped drive groove on the drive plate 603. Figure 10 As shown, the first doorpost guide groove on the first guide block 101 and the second doorpost guide groove on the second guide block 104 are also specially designed for the doorpost 7 structure. The doorpost guide groove structures on the two guide blocks are the same, each including an upper first groove 9 and a lower second groove 10. The lower end of the doorpost 7 is provided with a cover 704 and a column head 705 from top to bottom. The cover 704 is located in the first groove 9 and moves along the first groove 9. The column head 705 is located in the second groove 10. The present invention ensures accurate movement of the doorpost 7 through the cooperation of the above-mentioned pressure head and doorpost guide groove structure, thereby ensuring accurate pressing and minimizing pressure damage at the mating parts.

[0042] likeFigures 1 to 2 As shown, the platform 1 is provided with a support assembly for supporting the self-priming mechanism 5. In this embodiment, the support assembly includes a support block 102 and positioning posts 103, wherein the lower side of the self-priming mechanism 5 is placed on the support block 102, and the edge of the self-priming mechanism 5 is fixed by defining its position through the positioning posts 103. When the present invention is working, the first pressing assembly 2 and the second pressing assembly 3 move relative to each other from both sides to achieve pressing, and the forces on both sides of the self-priming mechanism 5 can be balanced to reduce the possibility of workpiece pressing damage.

[0043] In this embodiment, the driving element 4 can be a manual driving handle, wherein, for example... Figures 1 to 2 As shown, the platform 1 is provided with an arc-shaped third guide groove 106, the drive disk 603 is provided with a drive connecting plate 602, and the lower end of the manual drive handle passes through the third guide groove 106 and is fixedly connected to the drive connecting plate 602. The operator can drive the drive disk 603 to rotate by pushing the manual drive handle, thereby completing the pressing. The present invention can also adopt an automatic drive form according to actual needs, such as using a cylinder as the drive element 4. The front end of the cylinder is hinged to the drive connecting plate 602, and the rear end of the cylinder is hinged to a suitable position on the base plate 8. The extension and retraction of the cylinder drives the drive connecting plate 602 to move. At this time, a guide rod can be provided on the drive connecting plate 602 to pass through the third guide groove 106 to ensure drive guidance.

[0044] like Figure 3 As shown, in this embodiment, the base plate 8 is suspended under the platform 1 by a hanger rod 801.

[0045] The working principle of this invention is as follows:

[0046] like Figure 4 and Figure 6 As shown, in use, the press-fitting drive assembly 6 utilizes the rotation of the drive disc 603 to drive the drive linkages on both sides to close and move, thereby driving the first press-fitting assembly 2 and the second press-fitting assembly 3 to close and move to complete the press-fitting operation of the door post 7. The forces on both sides of the self-priming mechanism 5 can be balanced to reduce the possibility of workpiece damage during press-fitting. Furthermore, this invention can drive multiple pressure rods on both sides of the self-priming mechanism 5 to move simultaneously, thereby completing the press-fitting operation of multiple door posts 7 on both sides of the self-priming mechanism 5 at the same time. This simplifies operation and improves work efficiency. Figures 8 to 10As shown, due to the relatively special structure of the doorpost 7 targeted by this invention, the press head in the press assembly of this invention needs to be designed specifically, and the guide grooves on each guide block also need to be designed specifically. During press assembly, the upper outer side plate 7011 of the doorpost 7 is placed in the press groove 3033 of the corresponding press head, and the first protrusion 3031 of the press head abuts against the first annular protrusion 702 of the doorpost 7, and the second protrusion 3032 of the press head abuts against the second annular protrusion 703 of the doorpost 7. This ensures press assembly while preventing the press head from damaging other parts of the component. Furthermore, each press rod is installed on the corresponding press slide block by locking and clamping with locking bolts. This structure facilitates the replacement of press rods of appropriate specifications according to actual needs, and also facilitates the adjustment of the position and length of the press rods according to actual needs. This ensures press assembly while further preventing damage to components such as the doorpost 7.
