Detailed Description

The technical solutions in the exemplary embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the exemplary embodiments of the present disclosure. The example embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present disclosure, and it is therefore to be understood that various modifications and changes may be made to the example embodiments without departing from the scope of the present disclosure.

Unless specified or indicated otherwise, the terms "coupled," "affixed," and the like are to be construed broadly and are used interchangeably, and are intended to encompass, for example, fixed, removable, or integral, as well as direct, or indirect, via intermediaries. The specific meaning of the terms in the present disclosure may be understood by those skilled in the art according to the specific circumstances.

The principle of the turnbuckle is that the turnbuckle is telescopic by utilizing a screw rod, the connection length can be adjusted, and the turnbuckle can be used for adjusting the tightness of a steel wire rope and binding the components in component transportation. The inventor found that when the conventional stud bolt is used, the diameters of the threaded adjusting rods at the two ends are equal, when the connecting length of the stud bolt is shortened, the two adjusting rods move in opposite directions, and when the two adjusting rods are abutted, the stud bolt reaches the shortest length. Referring to fig. 1 to 2, when the connection length of the basket bolt is increased, the length of the basket bolt is longest when the two adjusting rods are moved away from each other to screw out the nuts at both ends. That is, the stroke of the adjusting of the basket bolt is the distance between the nuts at the two ends. In scenes where space is limited and adjustment travel is required to be long, the application of the stud bolts is limited.

To the above-mentioned problem, the present disclosure provides a basket bolt, refer to fig. 3 to 5, including first regulation pole 10, second regulation pole 20 and sleeve 30, be equipped with first external screw thread on the outer peripheral face of first regulation pole 10, be equipped with the second external screw thread on the outer peripheral face of second regulation pole 20, sleeve 30's both ends are equipped with respectively with first screw hole and the second screw hole that matches with the second external screw thread of first external screw thread, first regulation pole 10 screw in first screw hole and stretch into in the sleeve, second regulation pole 20 screw in second screw hole and stretch into in the sleeve.

Wherein, the first external screw thread and the second external screw thread are opposite in rotation direction, the first adjusting rod 10, the second adjusting rod 20 and the sleeve 30 are coaxial, one end of the second adjusting rod 20 opposite to the first adjusting rod 10 is provided with a containing cavity 21 coaxial with the second adjusting rod 20, and the diameter of the containing cavity 21 is not smaller than the outer diameter of the first adjusting rod 10.

With the use of the basket bolt according to the exemplary embodiment of the present disclosure, referring to fig. 3, the basket bolt is longest when the first and second adjusting

rods

10 and 20 are moved away from each other to the first and second screw holes to be unscrewed from both ends of the sleeve 30; when the first adjusting rod 10 and the second adjusting rod 20 move in opposite directions, referring to fig. 4, the first adjusting rod 10 can extend into the accommodating cavity 21 on the second adjusting rod 20, so that the first adjusting rod 10 and the second adjusting rod 20 are prevented from collision, the adjusting stroke of the basket bolt is increased, and a wider adjusting range can be provided under the environment with limited space.

Specifically, the first adjusting rod 10 and the second adjusting rod 20 may each be cylindrical, and the outer sides thereof are provided with left-handed external threads and right-handed external threads, respectively. For example, the first adjusting rod 10 has a left-handed first external thread on its outer circumferential surface, and the second adjusting rod 20 has a right-handed second external thread on its outer circumferential surface. The pitches of the first and second external threads may be the same, and of course, the pitches of the first and second screw holes to be matched thereto should be the same, so that the first and

second adjustment rods

10 and 20 are simultaneously moved the same distance to the outside or inside of the sleeve 30 when the sleeve 30 is rotated.

The sleeve 30 may be a hollow cylinder having first and second threaded holes at both ends thereof, respectively. In an exemplary embodiment, referring to fig. 5, a through hole 31 is formed between the first threaded hole and the second threaded hole, the through hole 31 communicates with the inner wall and the outer wall of the sleeve, and one or more through holes 31 may be formed in the sleeve 30, which is favorable for reducing the mass of the basket bolt, and is favorable for rotating the sleeve 30, and the capability of further increasing or shortening the connection distance of the basket bolt can be intuitively judged by observing the moving position of the first adjusting rod 10 and the second adjusting rod 20 in the current state from the through holes 31.

The sleeve 30 may also be composed of two nuts and several tie rods connected between the two nuts, the two nuts being provided with a first threaded hole and a second threaded hole respectively, which are matched with the threads of the first adjusting rod 10 and the second adjusting rod 20. For example, a left-handed first threaded hole is formed in one nut matched with the first adjusting rod 10, a right-handed second threaded hole is formed in the other nut matched with the second adjusting rod 20, a first external thread on the outer circumferential surface of the first adjusting rod 10 is matched with the first threaded hole and can move in a direction approaching or separating from the second threaded hole, and a second external thread on the outer circumferential surface of the second adjusting rod 20 is matched with the second threaded hole and can move in a direction approaching or separating from the first threaded hole.

In one exemplary embodiment of the present disclosure, the receiving cavity 21 may be a blind hole, and the depth of the receiving cavity 21 is not less than the length of the sleeve 30. When the first adjusting lever 10 and the second adjusting lever 20 are moved toward each other, the depth of the receiving cavity 21 affects the adjusting stroke of the basket bolt. The depth of the accommodating cavity 21 is greater than or equal to the length of the sleeve 30, so that when the second adjusting rod 20 moves toward the first threaded hole, it can move to a stroke stop near the first threaded hole without being affected by the first adjusting rod 10, thereby amplifying the adjusting stroke of the basket bolt by 2 times.

In an exemplary embodiment of the present disclosure, the bottom of the receiving cavity 21 may be provided with an elastic buffer, such as a rubber gasket or other cushion made of an elastic material, or the like. When the first adjusting rod 10 enters the accommodating cavity 21 and the stud bolt is further shortened, the elastic buffer member can prevent the first adjusting rod 10 from colliding with the bottom of the accommodating cavity 21 to damage the first adjusting rod 10 and the second adjusting rod 20 when the first adjusting rod 10 continues to move towards the bottom of the accommodating cavity 21.

In one exemplary embodiment of the present disclosure, the basket bolt may further include a stabilizing block provided to an inner wall of the sleeve, and a specific position of the stabilizing block may be between the first screw hole and the second screw hole, and be closer to the first screw hole than the second screw hole, and be spaced apart from the first screw hole. The stabilizing block is provided with a third threaded hole which is the same as and coaxial with the threads of the first threaded hole, and when the first adjusting rod 10 moves to the direction of the second threaded hole to pass through the stabilizing block and still needs to move continuously, the stabilizing block can be screwed in from the third threaded hole. The stabilizing block can improve the stability of the first adjusting rod 10 in the axial direction, keep the axis of the first adjusting rod 10 not to deviate, prevent the first adjusting rod 10 from deviating in the axial direction and not entering the accommodating cavity 21, and interfere with the second adjusting rod 20. In addition, the stabilizer block can also improve the strength of the stud.

In one exemplary embodiment of the present disclosure, as shown with reference to fig. 3 to 5, the basket bolt may further include a first coupling head 101, the first coupling head 101 being coupled to an end of the first adjustment lever 10 remote from the sleeve 30. The first connector 101 and the first adjusting rod 10 may be integrally formed, or may be directly connected to the first adjusting rod 10, or may be fixedly connected by a pull rod or the like, or may be telescopically connected by a telescopic pull rod, so as to further improve the adjusting stroke of the basket bolt, which is not particularly limited in the present disclosure. In an exemplary embodiment, the first coupling head 101 and the first adjustment lever 10 may be rotatably coupled by a hinge, a fish-eye bearing, or a movable shaft. The first connector 101 can be in a hook shape, for example, in a C shape, can be directly hooked on parts to be connected, is convenient to detach, can be applied to occasions where the basket bolts are required to be detached frequently, can also be in an annular shape, for example, in an O shape, and is installed on the parts to be connected in a bolt mode and the like, so that the parts to be connected are not easy to fall off, and the connection is firmer.

Of course, the stud may further include a second connector 201 connected to an end of the second adjustment lever 20 remote from the sleeve 30. The second connector 201 may be integrally formed with the second adjusting rod 20, or directly connected with the second adjusting rod 20 or fixedly or telescopically connected with the second adjusting rod 20 through a pull rod, or rotatably connected with the second adjusting rod 20 through a hinge, a fish-eye bearing or a movable shaft, which will not be described herein. The second connector 201 is also ring-shaped or hook-shaped.

The first connector 101 and the second connector 201 may have the same shape, or may have different shapes according to actual needs. When using the basket bolt, the first connector 101 and the second connector 201 are connected to two parts requiring adjustment of the distance or a wire rope or cable requiring tightening, respectively, and the distance between the first connector 101 and the second connector 201 can be adjusted by rotating the sleeve 30.
