[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Such as Figures 1 to 3As shown in the figure, a connection reinforcement structure proposed in this embodiment includes an electric slide table 1 and its own mobile end 101. The mobile end 101 is arranged in a U-shaped structure. Six iron blocks 2 are fixedly connected to both sides of the electric slide table 1 in a rectangular shape. The same mounting plate 3 is magnetically clamped on the six iron blocks 2 on the same side. On the mutually repulsive sides of the two mounting plates 3, dovetail-shaped slide rails 6 are welded and fixed. A slider 7 is slidably mounted on the dovetail-shaped slide rail 6. On the mutually close sides of two of the sliders 7, dovetail-shaped chutes 16 are opened. The dovetail-shaped chutes 16 are slidably connected to the corresponding dovetail-shaped slide rails 6, achieving the effect of guiding the forward and backward sliding of the slider 7;

[0023] On the top of the mutually repulsive sides of the two sliders 7, two grooves 9 are opened. Thread locking assemblies are embedded and fixed on the inner walls of the grooves 9. The mobile end 101 is movably sleeved on the four thread locking assemblies. On the inner wall of the groove 9 far from its opening, an elastic tension reinforcement assembly that tightly contacts the end of the corresponding thread locking assembly is fixedly connected. The thread locking assembly is used to thread-fix the mobile end 101 and the corresponding slider 7. The elastic tension reinforcement assembly is used to elastically tension the corresponding thread locking assembly, ensuring the continuous tightness and strength of the thread bite by means of tension, preventing the loosening and detachment of the thread connection due to factors such as vibration, and achieving the connection reinforcement effect. By sliding the slider 7 and the corresponding dovetail-shaped slide rail 6, the stable guiding and anti-tilting of the mobile end 101 are realized.

[0024] Specifically, the thread locking assembly includes an internal thread sleeve 8 embedded and fixed on the inner wall of the corresponding groove 9. An embedding groove fixedly connected to the outer side of the corresponding internal thread sleeve 8 is opened on the inner wall of the groove 9, achieving the effect of internally embedding and fixing the internal thread sleeve 8. An internal thread sleeve 8 is internally threaded with a T-shaped fixing bolt 10. The mobile end 101 is movably sleeved on the four T-shaped fixing bolts 10. On both sides of the mobile end 101, two circular grooves are opened. On the inner wall of the circular groove far from its opening, a bolt through-hole is opened. The T-shaped fixing bolt 10 is movably sleeved in the corresponding bolt through-hole and circular groove, achieving the effect of allowing the T-shaped fixing bolt 10 to pass through movably; The cooperation of the provided internal thread sleeve 8 and the T-shaped fixing bolt 10 realizes the threaded connection and fixation of the mobile end 101 and the corresponding slider 7 by the threaded connection of the T-shaped fixing bolt 10 and the internal thread sleeve 8.

[0025] Furthermore, the elastic tension reinforcement assembly includes a U-shaped seat 11 fixedly connected to the inner wall of the corresponding groove 9 away from the opening side thereof. A movable seat 14 is in sliding contact between the top inner wall and the bottom inner wall of the U-shaped seat 11. A compression spring 15 in a compressed state is fixedly connected between the side of the movable seat 14 close to the corresponding mounting plate 3 and the inner wall of the U-shaped seat 11 close to the mounting plate 3. A transverse guide rod 13 is fixedly connected to the side of the movable seat 14 away from the mounting plate 3. One end of the transverse guide rod 13 away from the corresponding movable seat 14 slides out of the U-shaped seat 11 and is fixedly connected with a pressing block 12. A transverse guide hole for slidably sleeving the outer side of the corresponding transverse guide rod 13 is formed in the inner wall of the U-shaped seat 11 away from the mounting plate 3, which serves to allow the transverse guide rod 13 to pass through and guide its transverse sliding. The side of the pressing block 12 close to the corresponding T-shaped fixing bolt 10 is arranged in an arc structure and is in tight contact with the end of the T-shaped fixing bolt 10. The U-shaped seat 11, the movable seat 14, the compression spring 15, the transverse guide rod 13 and the pressing block 12 are cooperated. The compression spring 15 in a compressed state elastically tensions the corresponding movable seat 14 in a direction away from the mounting plate 3, so as to drive the pressing block 12 to elastically tension the T-shaped fixing bolt 10 outward through the corresponding transverse guide rod 13. By means of elastic tension, a continuous elastic tension pressure can always be applied to the T-shaped fixing bolt 10, thereby continuously ensuring the threading engagement force and tightness between the T-shaped fixing bolt 10 and the internal thread sleeve 8, and reducing the phenomenon of subsequent loosening due to the loosening of the engagement caused by vibration factors.

[0026] Furthermore, six card slots 4 are formed in the adjacent sides of the two mounting plates 3. A magnet block 5 is fixedly connected to the inner wall of the card slot 4 away from the opening thereof. The iron card block 2 is movably clamped in the corresponding card slot 4 and adsorbed to the magnet block 5. The card slot 4, the magnet block 5 and the iron card block 2 are cooperated to realize magnetic adsorption clamping and positioning of the mounting plate 3. The two sides of the mobile end 101 block and limit the two sliders 7, and further block and limit the two mounting plates 3 through the two dovetail slide rails 6, so that the two mounting plates 3 cannot be separated outward, realizing the effect of limiting and fixing, and there is no need to separately use bolt parts to fix the mounting plate 3, improving the installation convenience.

[0027] Furthermore, four bolt mounting holes are formed in a rectangular shape at the top of the mobile end 101. The mutually repulsive sides of the two sliders 7 are in movable contact with the inner walls of the two sides of the mobile end 101 respectively. The provided bolt mounting holes are used for personnel to fixedly install another device of the present invention in the left-right direction on the top of the mobile end 101 through an external bolt when a cross slide table device is needed, so as to form a cross slide table device.

[0028] The usage method of this embodiment is as follows: Before the mobile terminal 101 is installed with the slider 7, first slide the slider 7 forward and remove it from the corresponding dovetail rail 6. At this time, a space for the dovetail rail 6 to move left and right is provided. Then move the dovetail rail 6 towards the electric sliding table 1, so that the corresponding mounting plate 3 is sleeved on the four iron blocks 2 through the four card slots 4. The mounting plate 3 drives the corresponding four magnet blocks 5 to adsorb on the corresponding iron blocks 2 respectively, realizing the preliminary magnetic adsorption and locking of the mounting plate 3.

[0029] At this time, slide the slider 7 backward through the corresponding dovetail groove 16 and sleeved on the dovetail rail 6. At this time, the repulsive sides of the two sliders 7 are respectively in contact with the inner walls on both sides of the mobile terminal 101. At this time, the two sides of the mobile terminal 101 block and limit the two sliders 7, and further block and limit the two mounting plates 3 through the two dovetail rails 6, so that the two cannot be separated outward, realizing the effect of restricting and fixing the mounting plate 3. There is no need to separately use bolt parts to fix the mounting plate 3, ensuring stable fixation while improving the convenience of installing the mounting plate 3 and the dovetail rail 6.

[0030] Screw the T-shaped fixing bolt 10 into the corresponding internal thread sleeve 8. As the T-shaped fixing bolt 10 is screwed in, its end presses on the extrusion block 12. Under the extrusion force, the extrusion block 12 moves towards the mounting plate 3 and drives the moving seat 14 to compress the compression spring 15 through the corresponding cross guide rod 13 until the T-shaped fixing bolt 10 is screwed in to press tightly on the mobile terminal 101, realizing the installation and fixation of the mobile terminal 101 and the two sliders 7. And at this time, the compressed compression spring 15 elastically tightens the corresponding moving seat 14 away from the mounting plate 3, so as to realize driving the extrusion block 12 to elastically tighten the T-shaped fixing bolt 10 outward through the corresponding cross guide rod 13. By using the elastic tightening method, a continuous elastic tightening pressure can always be exerted on the T-shaped fixing bolt 10, and thus the force and tightness of the thread engagement between the T-shaped fixing bolt 10 and the internal thread sleeve 8 can always be continuously ensured, reducing the phenomenon of loosening at the engagement due to vibration factors and resulting in subsequent inability to continuously bite and loosen, realizing the connection reinforcement effect and improving the long-term use stability. In addition, the bolt mounting holes provided at the top of the mobile terminal 101 can be used by personnel to fixedly install another such device left and right on the top of the mobile terminal 101 through external bolts when a cross slide table device is needed to form a cross slide table device.
