DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0019] Refer to Figure 1-2As shown, a high-strength straight-through joint comprises a screwing section 1 and connecting sections 2 arranged at both ends of the screwing section 1, a force-bearing plate 3 for contacting with a wrench is provided on either side wall of the screwing section 1, a receiving chamber 4 communicating with the outside is opened on the screwing section 1, an adjusting block 5 is slidably connected in the receiving chamber 4, and one end of the adjusting block 5 passes through the screwing section 1 and is fixedly connected to the force-bearing plate 3, a driving member for limiting the movement of the adjusting block 5 toward the axis of the screwing section 1 is provided in the receiving chamber 4, when the operator's wrench is too large, the wrench can be moved to make the screwing section 1 enter the bayonet at the end of the wrench, and then the operator can operate the driving member to drive the adjusting block 5 to move away from the receiving chamber 4 and at the same time, limit it to retract into the receiving chamber 4 when in use, then the adjusting block 5 drives the force-bearing plate 3 away from the screwing section 1 until the force-bearing plate 3 When the adjusting block 5 is moved back into the accommodating chamber 4, the distance between the tightening section 1 and the force plate 3 gradually narrows, so that a small wrench can be adapted. The distance between the force plate 3 and the tightening section 1 is changed by sliding the adjusting block 5 in the accommodating chamber 4, so that the operator can freely adjust the distance between the tightening section 1 and the force plate 3 according to wrenches of different sizes, so that the straight-through joint has better flexibility, thereby improving the adaptability between the wrench and the joint.

[0020] See Figure 1-2As shown, an adjustment section 6 is integrally formed between the screwing section 1 and the connecting section 2 at one end thereof. The driving member is a rotating sleeve 7 threadedly connected to the adjustment section 6 and used to extend into the accommodation cavity 4. An inclined surface for abutting against the rotating sleeve 7 is provided at the bottom of the adjustment block 5. When it is necessary to increase the distance between the force-bearing plate 3 and the screwing section 1, the operator can screw the rotating sleeve 7 to move it in the direction of the accommodation cavity 4 and make its end extend into the accommodation cavity 4 until the rotating sleeve 7 abuts against the inclined surface at the bottom of the adjustment block 5. At this time, if the rotating sleeve 7 is further screwed, the rotating sleeve 7 advances to exert a thrust on the adjustment block 5. Due to the action of the inclined surface of the adjustment block 5, the thrust exerted by the rotating sleeve 7 on the adjustment block 5 generates a component force perpendicular to the thrust direction on the inclined surface, thereby driving the adjustment block 5 to slide away from the accommodation cavity 4, and further realizing an increase in the distance between the force-bearing plate 3 and the screwing section 1. When it is necessary to decrease the distance between the force-bearing plate 3 and the screwing section 1, screw the rotating sleeve 7 to move it away from the accommodation cavity 4 until the rotating sleeve 7 is separated from the adjustment block 5. Then, the thrust exerted by the rotating sleeve 7 on the adjustment block 5 disappears. At this time, the operator can press the force-bearing plate 3 to drive the adjustment block 5 to move back into the accommodation cavity 4, thereby reducing the distance between the force-bearing plate 3 and the screwing section 1. Through the cooperation between the rotating sleeve 7 and the inclined surface of the adjustment block 5, the change in the distance between the force-bearing plate 3 and the screwing section 1 can be easily controlled. At the same time, the threaded connection between the rotating sleeve 7 and the adjustment section 6 has good self-locking property, so that the adjustment block 5 has a relatively stable support for the extended force-bearing plate 3, and the distance between the force-bearing plate 3 and the screwing section 1 can be kept stable.

[0021] Refer to Figure 1-2As shown, a receiving groove 8 for receiving the force-bearing plate 3 is provided on the side wall of the screwing section 1, and the depth of the receiving groove 8 is equal to the thickness of the force-bearing plate 3. The force-bearing plate 3 is detachably connected to the receiving groove 8 through a connecting member. In the natural state of the straight-through joint, the force-bearing plate 3 can be installed and retracted into the receiving groove 8 and fixed through the connecting member. Since the depth of the receiving groove 8 is equal to the thickness of the force-bearing plate 3, the side wall of the screwing section 1 is relatively flat in the natural state, thus avoiding the influence on the normal use of the straight-through joint due to the presence of the force-bearing plate 3 and the adjusting block 5. The connecting member includes magnetic sheets 9 respectively arranged on the bottom wall of the receiving groove 8 and the bottom of the force-bearing plate 3, and the magnetic sheet 9 on the bottom wall of the receiving groove 8 attracts the magnetic sheet 9 on the bottom of the force-bearing plate 3. In the process of retracting the force-bearing plate 3 into the receiving groove 8, as the force-bearing plate 3 continuously enters the receiving groove 8, the magnetic sheet 9 on the force-bearing plate 3 approaches the magnetic sheet 9 on the bottom wall of the receiving groove 8 until the two attract each other. At this time, the force-bearing plate 3 is stably fixed in the receiving groove 8. When the screwing sleeve 7 is rotated to move the force-bearing plate 3 away from the screwing section 1, as the sleeve 7 rotates continuously, the adjusting block 5 is pushed by the sleeve 7, and then a thrust is applied to the force-bearing plate 3, thereby driving the mutually attracting magnetic sheets 9 to separate from each other, and the force-bearing plate 3 can be disengaged from the receiving groove 8. Through the mutual attraction and separation of the magnetic sheets 9, the fixing and disengagement of the force-bearing plate 3 in the receiving groove 8 are realized, and the operation is relatively convenient.

[0022] Referring to Figure 1-3 As shown, a limiting piece 10 for restricting the sliding of the adjusting block 5 is provided at the bottom of the adjusting block 5, and a limiting groove 11 for the limiting piece 10 to be embedded is provided on the inner wall of the receiving cavity 4. In the process of the adjusting block 5 driving the force-bearing plate 3 away from the screwing section 1, when the limiting piece 10 is embedded in the limiting groove 11, the limiting groove 11 has a limiting effect on the limiting piece 10, thereby restricting the continuous sliding of the adjusting block 5, and avoiding the adjusting block 5 from completely disengaging from the receiving cavity 4, so that a stable connection relationship is always maintained between the adjusting block 5 and the screwing section 1. A plurality of anti-slip grooves 12 are circumferentially provided on the outer peripheral wall of the screwing sleeve 7. By providing the anti-slip grooves 12, the friction coefficient of the surface of the screwing sleeve 7 is increased, so that it is not easy for the operator to slip when screwing the screwing sleeve 7, and thus the process of the operator screwing the screwing sleeve 7 to control the sliding of the adjusting block 5 is relatively labor-saving. The screwing section 1, the connecting section 2, the adjusting section 6 and the screwing sleeve 7 are all made of stainless steel material. The stainless steel material has high strength and corrosion resistance, so that the whole straight-through joint has high strength and long service life.

[0023] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
