Description

Technical Field

[0001] The utility model relates to a buckle-type clamping sleeve structure, in particular to a buckle-type clamping sleeve structure with a draw hook. Background Art

[0002] The first common type of existing lever-type clamp-type collar structures uses an eccentric structure. Specifically, a transverse rod placed across the notch does not swing. One end of the transverse rod is connected to a lever, allowing the lever and transverse rod to rotate relative to each other. The lever's end near the transverse rod is shaped like an ellipse. With the axis of rotation formed by the connection between the transverse rod and the lever as the axis, when the lever is turned to the locked position, the long axis of the ellipse pushes against the collar, narrowing the notch and clamping the tube. Conversely, when the lever is turned to the relaxed position, the short axis of the ellipse moves toward the collar. At this point, the force exerted by the long axis on the collar disappears, widening the notch and loosening the tube. Long-term use of this method can easily cause wear on the long axis of the ellipse, reducing the clamping force of the collar.

[0003] The second common type of existing buckle-type clamping sleeve structure is a transverse rod placed horizontally across the notch that swings. One end of the transverse rod is connected to a buckle, and the buckle and the transverse rod can rotate relative to each other. A fulcrum on the buckle presses against a preset position on the outside of the sleeve. With the fulcrum as the axis, the buckle is pulled to the locked state, and the transverse rod swings closer to the tube. At this time, the rotation axis formed by the connection between the transverse rod and the buckle is away from the notch. The fulcrum presses against the sleeve, causing the notch to narrow and the sleeve to clamp the tube. Conversely, when the buckle is pulled to the loose state, the transverse rod swings away from the tube. At this time, the rotation axis formed by the connection between the transverse rod and the buckle is close to the notch. The force of the fulcrum pressing against the sleeve disappears or weakens, causing the notch to widen and the sleeve to loosen the tube. This method requires that the extensions on both sides of the notch be lengthened because a space is reserved for the transverse rod to swing. This increases the outer diameter of the overall sleeve, affecting the storage size and portability. Utility Model Content

[0004] In order to overcome the wear problem of the existing buckle type clamp type sleeve structure after long-term use or the inconvenience caused by the storage size, the utility model provides a buckle type clamp type sleeve structure with a draw hook, with the fulcrum as the rotation axis, when the operating part is pulled in the locking direction, the draw hook rotates with the shaft hole as the axis, the draw hook tightens the fixing rod, the extension part is pushed, the notch is reduced, and the pipe sleeve clamps the first pipe and fixes each other. Conversely, with the fulcrum as the rotation axis, when the operating part is pulled in the loosening direction, the draw hook is rotated with the shaft hole as the axis. The shaft hole rotates around the axis, the pull hook relaxes the fixed rod, the extension part is not pushed and the notch is widened, then the tube sleeve relaxes the first tube and slides with each other. The utility model utilizes the pull hook to rotate with the operating part to tighten the fixed rod, and the fixed rod itself does not rotate, that is, the utility model utilizes the rotation of the pull hook to replace the horizontal rod swing of the horizontal rod technology of the second common technology, so as to achieve the effect of shortening the extension part, reducing the overall outer diameter of the bundle sleeve, increasing the convenience of carrying, and making the pull of the buckle more labor-saving.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a pull-button type clamping sleeve structure with a draw hook can be used to be fixed on the first tube, characterized in that: a tube sleeve, the tube sleeve has a first accommodating portion and a notch, the tube sleeve has two mutually corresponding extension portions extending outward along the direction of the notch, the extension portions respectively have a through hole, and a fulcrum is provided at an appropriate position on the outside of one of the extension portions; and a fixing rod, one end of the fixing rod has a rotating shaft hole; and a pull-button, the pull-button has a fulcrum portion, a draw hook accommodating portion and an operating portion, the draw hook accommodating portion has a draw hook hole; and a draw hook; and wherein, the draw hook is inserted into the rotating shaft hole of the fixing rod, the fixing rod passes through the draw hook hole so that the two sides of the draw hook are hung in the draw hook accommodating portion, and the draw hook is inserted into the rotating shaft hole of the fixing rod. The fixing rod passes through the two through holes so that the fulcrum part is pressed into the fulcrum position, and the pull buckle is installed on the tube sleeve by means of the pull hook, and the first tube is inserted into the first accommodating part. With the fulcrum part as the rotation axis, when the operating part is pulled in the locking direction, the pull hook rotates with the shaft hole as the axis, the pull hook tightens the fixing rod, the extension part is pushed, the notch is reduced, and the tube sleeve clamps the first tube and fixes them to each other. Conversely, with the fulcrum part as the rotation axis, when the operating part is pulled in the loosening direction, the pull hook rotates with the shaft hole as the axis, the pull hook relaxes the fixing rod, the extension part is not pushed, the notch is widened, and the tube sleeve relaxes the first tube and slides with each other.

[0006] Preferably, the feature is that there is further a second tube and an outer tube sleeve, the second tube sleeve is arranged on the outside of the first tube to form a telescopic tube with a gap between them, the outer tube sleeve is connected to the tube sleeve and has a second accommodating portion, the second accommodating portion is communicated with the first accommodating portion, one end of the second tube is inserted into the second accommodating portion, and the second tube and the outer tube sleeve are fixed to each other by a fastener.

[0007] The beneficial effect of the present invention is that the present invention utilizes the draw hook to rotate with the operating part to tighten the fixing rod, and the fixing rod itself does not rotate. That is, the present invention utilizes the rotation of the draw hook to replace the swing of the transverse rod of the second common technology of the existing transverse rod, so as to achieve the effect of shortening the extended part and reducing the overall outer diameter of the bundle sleeve. The present invention can increase the convenience of storage and carrying, avoid problems caused by wear, and save more effort when using the pull buckle. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following is based on Figures 1A to 7B , is to illustrate the implementation of the present invention. This description is not intended to limit the implementation of the present invention, but is one of the embodiments of the present invention.

[0045] like Figures 1A to 5B As shown in FIG. 1 , a buckle-type clip-on sleeve structure with a draw hook is provided according to the first embodiment of the present invention. Figure 1A and Figure 1B , can be used to fix in the first tube 2, characterized in that: Figure 2 , a pipe sleeve 1, the pipe sleeve 1 has a first accommodating portion 11 and a notch 12, the pipe sleeve 1 extends outward along the direction of the notch 12 to have two mutually corresponding extension portions 13, the extension portions 13 respectively have a through hole 131, and one of the extension portions 13 is appropriately provided with a support point 14 at the outer side; and a fixing rod 3, one end of the fixing rod 3 has a rotating shaft hole 31; and a pull buckle 4, such as Figure 3A The pull button 4 has a fulcrum portion 41, a hook receiving portion 42 and an operating portion 43, the hook receiving portion 42 has a hook hole 421; and a hook 5; and wherein the hook 5 is inserted into the shaft hole 31 of the fixing rod 3, as shown Figure 3B The fixing rod 3 passes through the hook hole 421 so that the two sides of the hook 5 are hung in the hook receiving portion 42, and the fixing rod 3 passes through the two through holes 131 so that the fulcrum portion 41 is pressed against the fulcrum position 14. Figure 4B , the pull button 4 is installed on the pipe sleeve 1 through the pull hook 5, and the first pipe 2 is inserted into the first accommodating portion 11, with the fulcrum portion 41 as the rotation axis, as shown Figure 4A When the operating portion 43 is pulled in the locking direction, the draw hook 5 rotates with the shaft hole 31 as the axis, the draw hook 5 tightens the fixing rod 3, the extension portion 13 is pushed, the notch 12 shrinks, and the pipe sleeve 1 clamps the first pipe 2 and fixes them to each other. Conversely, with the fulcrum portion 41 as the rotation axis, Figure 4B When the operating portion 43 is pulled in the direction of loosening, the draw hook 5 rotates with the shaft hole 31 as the axis, the draw hook 5 loosens the fixing rod 3, the extension portion 13 is not pushed, the notch 12 is widened, and the tube sleeve 1 loosens the first tube 2 and slides against each other. The main purpose of the invention is to use the draw hook 5 to rotate with the operating portion 43 to tighten the fixing rod 3. The fixing rod 3 itself does not rotate or swing. That is, the utility model uses the rotation of the draw hook 5 to replace the swing of the horizontal rod of the second common technology, so as to achieve the effect of shortening the extension part, reducing the overall outer diameter of the bundle, increasing the convenience of carrying, and making the pull of the buckle 4 more labor-saving, which is significantly different from the existing technology.

[0046] like Figure 5A and Figure 5BAs shown in the figure, the relative position relationship between the hook receiving portion 42 and the extension portion 13 in the locked state and the relaxed state of the embodiment 1 of the present invention is shown. With the fulcrum portion 41 as the rotation axis, when the operating portion 43 is pulled in the locking direction, the hook 5 rotates with the shaft hole 31 as the axis, and the hook 5 tightens the fixing rod 3. Figure 5A , the hook accommodating portion 42 will be away from the notch 12 and the extension portion 13, so the extension portion 13 is pushed, the notch 12 is reduced, and the pipe sleeve 1 clamps the first pipe 2 and fixes each other. On the contrary, when the operating portion 43 is pulled in the loosening direction with the fulcrum portion 41 as the rotation axis, the hook 5 rotates with the shaft hole 31 as the axis, and the hook 5 loosens the fixing rod 3. Figure 5B The hook receiving portion 42 is close to the notch 12 and the extension portion 13, so the extension portion 13 is not pushed. When the notch 12 is enlarged, the sleeve 1 loosens the first tube 2 and slides against each other.

[0047] like Figures 4A to 5B As shown, when the pipe sleeve 1 of the first embodiment of the present invention clamps the first pipe 2, as shown in FIG. Figure 4A and Figure 5A , the operating portion 43 will lean against the sleeve 1, and vice versa, when the sleeve 1 releases the first tube 2, as shown in FIG. Figure 4B and Figure 5B , the operating portion 43 will move away from the pipe sleeve 1. The relationship between the pulling direction of the trigger 4 and locking or loosening described in this embodiment is only one embodiment of the present invention. Other embodiments may have the opposite situation. For example, when the pipe sleeve 1 clamps the first pipe 2, the operating portion 43 of the trigger 4 will move away from the pipe sleeve 1.

[0048] like Figure 2 、 Figure 3A 、 Figure 4A and Figure 4BAs shown, the pipe sleeve 1 of the first embodiment of the present invention can be provided with a fulcrum positioning hole 15 at the corresponding position of the fulcrum position 14, and a fulcrum positioning column 411 can be extended outward on both sides of the fulcrum portion, so that the fulcrum portion 41 is pressed against the fulcrum position 14, and the two fulcrum positioning columns 411 are respectively engaged with the two fulcrum positioning holes 15. When the operating portion 43 is pulled in the locking direction with the fulcrum portion 41 as the rotation axis, the fulcrum positioning column 411 rotates accordingly in the fulcrum positioning hole 15, and the pull hook 5 rotates with the shaft hole 31 as the axis, and the pull hook 5 tightens the fixing rod 3. The extended portion 13 can be pushed by the fulcrum portion 41 and the fulcrum positioning column 411 at the same time, and the notch 12 is reduced, so that the pipe sleeve 1 clamps the first tube 2 and fixes them to each other. In this embodiment, in order to make the pushing force of the fulcrum part 41 on the pipe sleeve 1 more uniform, the fulcrum positioning hole 15 and the fulcrum part positioning column 411 are provided, but it is not intended to limit the present invention to requiring the fulcrum positioning hole 15 and the fulcrum part positioning column 411.

[0049] like Figure 2 、 Figure 5A and Figure 5B As shown, the fixing rod 3 of the first embodiment of the present invention has the shaft hole 31 at one end and a nut 32 at the other end for fixing the fixing rod 3 to the pipe sleeve 1. The nut in this embodiment is only one embodiment and is not intended to limit the fixing method of the fixing rod of the present invention.

[0050] like Figure 2 and Figure 3B As shown, the fixing rod 3 of the first embodiment of the present invention is flat at one end of the shaft hole 31. This is only one embodiment and is not intended to limit the shape of the end of the fixing rod 3 of the present invention. It can also be other shapes, such as cylindrical.

[0051] like Figures 6 to 7B As shown, this is the second embodiment of the present invention, which is characterized by a second tube 6 and an outer tube sleeve 7. Figure 6 The second tube 6 is sleeved on the outside of the first tube 2 to form a telescopic tube with a gap between them. The outer tube sleeve 7 is connected to the tube sleeve 1 and has a second accommodating portion 71. The second accommodating portion 71 is connected to the first accommodating portion 11. One end of the second tube 6 is inserted into the second accommodating portion 71. A fastener 8 is used to fix the second tube 6 and the outer tube sleeve 7 to each other, with the fulcrum portion 41 as the rotation axis. Figure 7AWhen the operating portion 43 is pulled in the locking direction, the draw hook 5 rotates with the shaft hole 31 as the axis, the draw hook 5 tightens the fixing rod 3, the extension portion 13 is pushed, the notch 12 shrinks, and the pipe sleeve 1 clamps the first pipe 2, so that the first pipe 2 and the second pipe 6 are fixed to each other. Conversely, with the fulcrum portion 41 as the rotation axis, as shown in FIG. Figure 7B When the operating portion 43 is pulled in the loosening direction, the hook 5 rotates about the shaft hole 31, the hook 5 loosens the fixing rod 3, the extension portion 13 is not pushed, the notch 12 is widened, and the sleeve 1 loosens the first tube 2, allowing the first tube 2 and the second tube 6 to slide relative to each other. The second embodiment of the present invention is used to adjust the length of the telescopic tube, and has a wide range of practical applications, such as the sleeve structure of the middle tube telescopic tube or leg telescopic tube of a tripod. The clamping method of fixing the outer tube sleeve 7 and the second tube 6 described in this embodiment is only one embodiment and does not limit the fixing method of the outer tube sleeve 7 and the second tube 6. Other fixing methods, such as a push-type structure, can also fix the outer tube sleeve 7 and the second tube 6 to each other.

[0052] The above description and explanation are only the description of the preferred embodiment of the present invention. Those with ordinary knowledge in this technology may make other modifications based on the scope of the patent application defined below and the above description.
