[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] like Figures 1 to 4 As shown, an embodiment of the present invention provides a self-locking and fixing device for an energy-gathering tube, which includes a base 10, a connecting rod 20 and a top plate 30. The base 10 is used to connect the tube body 100 of the energy-gathering tube, and the two ends of the connecting rod 20 are correspondingly connected to the base 10 and the top plate 30. A sliding rail 40 is provided on the connecting rod 20, and a slider 50 is provided on the sliding rail 40. The sliding rail 40 extends from the base 10 to the top plate 30 and is inclined in a direction away from the connecting rod 20. The slider 50 has a first position and a second position on the sliding rail 40. When the slider 50 moves from the first position to the second position, the distance between the slider 50 and the connecting rod 20 gradually increases, so that the slider 50 can gradually abut the inner wall of the blasting hole, so that the energy-gathering tube is fixed to the blasting hole.

[0030] Specifically, the base 10 is tightly connected to the body 100 of the energy-gathering tube, ensuring that the energy-gathering tube can be securely installed in the blasting hole. The two ends of the connecting rod 20 are respectively connected to the base 10 and the top plate 30, forming a stable frame structure, which not only enhances the stability of the entire device, but also allows the length or tilt angle of the connecting rod 20 to be adjusted to accommodate blasting holes of different depths and diameters. The slide rail 40 extends along the length of the connecting rod 20, and its tilt direction is in the direction away from the axis of the connecting rod 20, so that the slider 50 can gradually expand outward when moving along the slide rail 40, thereby effectively increasing the contact area with the inner wall of the blasting hole.

[0031] That is, when the slider 50 moves from the first position to the second position, the distance between the slider 50 and the connecting rod 20 gradually increases due to the inclined design of the slide rail 40. This change allows the slider 50 to gradually approach and abut the inner wall of the blasthole, thereby firmly fixing the energy-gathering tube inside the blasthole through friction and pressure. This makes the fixing device adaptable to blastholes of various shapes and sizes, providing greater installation flexibility and accuracy.

[0032] In summary, the self-locking fixing device for the energy-gathering tube provided in the embodiment of the present invention realizes a stable and flexible fixing method through the ingenious combination of the base 10, the connecting rod 20 and the top plate 30, and the innovative design of the slide rail 40 and the slider 50, which not only improves the installation efficiency and safety of the energy-gathering tube in the blasting hole, but also provides a more reliable and efficient solution for various blasting projects.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, multiple slide rails 40 are provided, and multiple slide rails 40 are arranged at equal angles along the outer periphery of the connecting rod 20. The sliders 50 are arranged one-to-one with the slide rails 40. This not only improves the overall stability of the energy-gathering tube self-locking fixture, but also enables the device to more evenly distribute the pressure on the inner wall of the blasting hole. This helps to reduce the risk of deformation or damage to the blasting hole due to concentrated pressure, thereby improving the safety and efficiency of the blasting operation. In this embodiment, there are four slide rails 40.

[0034] Furthermore, the slide rail 40 includes a trapezoidal guide plate 41 , the small end 411 of the trapezoidal guide plate 41 is arranged close to the base 10 , the large end 412 of the trapezoidal guide plate 41 is arranged close to the top plate 30 , and the slider 50 is provided with a guide groove 51 matching the trapezoidal guide plate 41 .

[0035] Specifically, the small end 411 of the trapezoidal guide plate 41 is positioned near the base 10, while the large end 412 is positioned near the top plate 30. This design allows the slide rail 40 to extend along the length of the connecting rod 20 while also having a certain inclination angle. As the slider 50 moves on the trapezoidal guide plate 41, the inclined design of the guide plate allows the slider 50 to gradually expand outward, achieving closer contact with the inner wall of the blasthole.

[0036] The slider 50 is provided with a guide groove 51 that matches the trapezoidal guide plate 41. The shape and size of the guide groove 51 closely match the trapezoidal guide plate 41, ensuring the stability and controllability of the slider 50 during movement. As the slider 50 moves along the trapezoidal guide plate 41, the guide groove 51 guides the slider 50 along a predetermined path, thereby preventing the slider 50 from shifting or falling off during movement.

[0037] Furthermore, the design of the trapezoidal guide plate 41 also incorporates a self-locking feature. When the slider 50 reaches the larger end 412 of the trapezoidal guide plate 41, the guide plate's tilt angle and the weight of the slider 50 naturally cause it to move toward the inner wall of the blasthole and tightly abut against it. This self-locking feature not only enhances the stability of the energy-gathering tube's self-locking fixture but also helps reduce the risk of the slider 50 moving or falling due to external factors (such as wind and vibration).

[0038] like Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, the guide groove 51 is configured to be inclined. As the slider 50 moves from the small end 411 to the large end 412 of the trapezoidal guide plate 41, the inclined design of the guide groove 51 allows the slider 50 to gradually expand outward, achieving closer contact with the inner wall of the blasthole. This design not only improves the fit between the slider 50 and the inner wall of the blasthole, but also helps reduce the friction and resistance generated by the movement of the slider 50.

[0039] Furthermore, the slider 50 is provided with an anti-slip pad or anti-slip texture, which not only improves the anti-slip performance of the energy-gathering tube self-locking fixing device, but also enhances the stability and safety of the entire device.

[0040] like Figure 1 and Figure 2 As shown, in some embodiments, the self-locking fixture for the energy-gathering tube further includes an elastic member 60. One end of the elastic member 60 is connected to the base 10, and the other end is connected to the slider 50. This allows the slider 50 to be subjected to a continuous push or pull from the elastic member 60 during movement, thereby ensuring that the slider 50 is tightly attached to the inner wall of the blasthole. In this embodiment, the elastic member 60 is configured as a spring, which is sleeved around the outside of the connecting rod 20. The base 10 is provided with a positioning groove 11 for accommodating the spring to prevent it from shifting.

[0041] In some embodiments, the edge of the top plate 30 is provided with an inclined guide surface 31, so that the top plate 30 can slide into the hole more smoothly when contacting the blasting hole, avoiding obstruction or damage caused by shape mismatch or improper angle.

[0042] like Figure 2As shown, in some embodiments, the self-locking fixing device of the energy-gathering tube further includes a plug-in tube 70, which is connected to the base. The plug-in tube 70 can be movably inserted into the tube body 100 of the energy-gathering tube. A plurality of through holes 71 are provided on the plug-in tube 70, and the through holes 71 are arranged in a one-to-one correspondence with the energy-gathering holes 110 on the tube body 100. This not only ensures that the energy-gathering tube is accurately placed at a predetermined position in the blasting hole, but also when the plug-in tube 70 is inserted into the energy-gathering tube, these through holes 71 can ensure that the energy-gathering hole 110 remains unobstructed, thereby ensuring the effective transmission and release of energy when the explosive explodes, thereby achieving fine control over the blasting effect and range.

[0043] Furthermore, the self-locking fixture for the focused tube also includes a shock-absorbing pad or coating, which is located on the outside of the plug tube 70 to absorb and dissipate the shock energy from the explosion. In other words, when the explosive detonates within the focused tube, it generates tremendous impact and vibration. The shock-absorbing pad or coating effectively absorbs and dissipates this energy, thereby protecting the plug tube 70 and the fixture from damage.

[0044] In addition, if Figure 1 As shown, an embodiment of the present invention further provides an energy-gathering tube, which includes a tube body 100 and the energy-gathering tube self-locking and fixing device of the above embodiment. The energy-gathering tube self-locking and fixing device is connected to the tube body 100 through a base 10.
