Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of rod fixing mechanism, and particularly relates to a fixing structure of a sliding groove rod. BACKGROUND

[0002] The sliding groove rod is a rod with a waist-shaped through hole, which is often connected with an external component through a bolt. The sliding groove rod connected with the external component can move along the sliding groove or / and rotate along the bolt. In the prior art, the bolt passes through the sliding groove of the rod and is screwed into the screw hole of the external component. When it is necessary to lock the sliding groove rod, the bolt is screwed to press the sliding groove rod, and the friction force generated by the pressing is used to limit the movement of the sliding groove rod. Since the contact area between the bolt and the sliding groove rod is limited and the friction force is difficult to effectively fix the sliding groove rod, a fixing structure of the sliding groove rod with better fastening capacity is needed. SUMMARY

[0003] The present application mainly relates to the technical field of rod fixing mechanism, and particularly relates to a fixing structure of a sliding groove rod.

[0004] To solve the above technical problems, the present application adopts the following technical scheme:

[0005] A fixing structure of a sliding groove rod, comprising a bolt, a sliding block and a rod group, a plurality of sliding blocks are distributed along the circumference of the bolt, and the sliding blocks are connected with the rod group; the bolt is screwed into the external component after penetrating the strip-shaped hole of the external sliding groove rod, and in the process of penetrating the external component, the sliding block is pushed obliquely to move away from the bolt and be pressed with the external sliding groove rod, so as to push the rod group to be close to the hole wall of the strip-shaped hole.

[0006] As a further improvement of the above technical scheme:

[0007] The head of the bolt is in the shape of an inverted circular truncated cone, one end of the sliding block is formed with an arc surface matched with the head, and the sliding block is clamped between the head and the external sliding groove rod; in the process of the bolt penetrating the external component, the head generates an oblique pressure on the arc surface.

[0008] Two sliding blocks are distributed on both sides of the bolt along the length direction of the strip-shaped hole, and two sliding blocks on the same side are connected with the same rod group; the rod group comprises two X-shaped supporting rods hinged together, the proximal end of the supporting rod is hinged with the sliding block, and the distal end of the supporting rod extends into the strip-shaped hole.

[0009] One sliding block is distributed on both sides of the bolt along the width direction of the strip-shaped hole, and one rod group is distributed on both sides of the bolt along the length direction of the strip-shaped hole; the rod group comprises two X-shaped supporting rods hinged together, the proximal end of the supporting rod is hinged with the sliding block, and the distal end of the supporting rod extends into the strip-shaped hole.

[0010] The support rod is in Z shape, which is composed of upper cross rod, vertical rod and lower cross rod in sequence, the proximal end of the upper cross rod is hinged with the sliding block, the lower cross rod is located in the strip-shaped hole, and the two ends of the lower cross rod are synchronously close to the hole wall of the strip-shaped hole in the process that the bolt is deeply inserted into the external component.

[0011] The two ends of the lower cross rod are hinged with the patch.

[0012] A plurality of sliding blocks are distributed on both sides of the bolt along the length direction of the strip-shaped hole, and each sliding block is hinged with a rod group; the rod group comprises two connecting rods and two X-shaped hinged support rods, the proximal end of the connecting rod is hinged with the sliding block, the distal end of the connecting rod is hinged with the proximal end of the support rod, and the distal end of the support rod is inserted into the strip-shaped hole.

[0013] The connecting rod is arranged as a folding rod, and the support rod is located in the strip-shaped hole, and the two ends of the support rod are synchronously close to the hole wall of the strip-shaped hole in the process that the bolt is deeply inserted into the external component.

[0014] The two ends of the support rod are hinged with the patch.

[0015] The two support rods of the same rod group are hinged through a hinge shaft; the fixing structure further comprises a limiting sleeve rod, the limiting sleeve rod comprises a main ring sleeved on the bolt and a secondary ring sleeved on the hinge shaft, and the main ring and the secondary ring are connected through a pull rod.

[0016] Compared with the prior art, the advantages of the present application are that:

[0017] When the bolt is screwed to move downwardly and inserted into the screw hole of the external component, the head pushes the sliding block obliquely downwardly, the vertical component of the pressure makes the sliding block and the external sliding groove rod gradually be pressed, and the horizontal component of the pressure makes the sliding block gradually move away from the bolt, since the sliding block is connected with the rod group, the rod group moves along with the sliding block during the movement of the sliding block, so that the distal end or the patch hinged on the distal end of the rod group is gradually close to the hole wall of the strip-shaped hole, the normal pressure is generated on the hole wall, and the stability of the fixing of the sliding groove rod is improved. That is to say, by screwing the bolt, the sliding block generates both vertical extrusion and horizontal pushing on the external sliding groove rod, and compared with the prior art which directly uses the head of the bolt to vertically extrude the external sliding groove rod, the additional horizontal pushing of the present application can enhance the connection stability of the external sliding groove rod and the external component to a certain extent, that is, the fastening capacity of the fixing structure is improved.

DETAILED DESCRIPTION

[0024] The application will be further described in detail below in conjunction with the accompanying drawings and specific examples.

[0025] Example 1

[0026] As Figure 1 and Figure 2As shown, the fixing structure of the sliding groove rod piece of the embodiment comprises a bolt 1, a sliding block 2 and a rod piece group 3, a plurality of sliding blocks 2 are distributed along the circumference of the bolt 1, and the sliding block 2 is connected with the rod piece group 3; the bolt 1 is in thread connection with an external component 5 after penetrating through a strip-shaped hole 41 of an external sliding groove rod piece 4, and in the process of penetrating into the external component 5, the bolt 1 pushes the sliding block 2 obliquely so that the sliding block 2 moves away from the bolt 1 and is extruded with the external sliding groove rod piece 4, and then pushes the rod piece group 3 to be close to the hole wall of the strip-shaped hole 41. Specifically, the head 11 of the bolt 1 is in the shape of an inverted circular truncated cone, one end of the sliding block 2 is formed with an arc surface 21 which is fitted with the head 11, and the sliding block 2 is clamped between the head 11 and the external sliding groove rod piece 4; in the process of the bolt 1 penetrating into the external component 5, the head 11 generates an oblique pressure on the arc surface 21. In assembly, the external sliding groove rod piece 4 is stacked on the upper surface of the external component 5, the sliding block 2 is stacked on the upper surface of the external sliding groove rod piece 4, and the bolt 1 is vertically penetrated through the strip-shaped hole 41 of the external sliding groove rod piece 4 from top to bottom and then is in thread connection with the external component 5, at this time, the head 11 of the bolt 1 is located above the external sliding groove rod piece 4 and abuts against the sliding block 2. Since the head 11 of the bolt 1 is in the shape of an inverted circular truncated cone, and the sliding block 2 is formed with the arc surface 21 which is fitted with the head 11, when the bolt 1 is screwed to move downwardly into the threaded hole of the external component 5, the head 11 pushes the sliding block 2 obliquely downwardly, the vertical component force of the pressure makes the sliding block 2 gradually press tightly with the external sliding groove rod piece 4, and the horizontal component force of the pressure makes the sliding block 2 gradually move away from the bolt 1, since the sliding block 2 is connected with the rod piece group 3, the rod piece group 3 moves with the sliding block 2 in the moving process of the sliding block 2, so that the distal end of the rod piece group 3 is gradually close to the hole wall of the strip-shaped hole 41. That is to say, by screwing the bolt 1, the sliding block 2 generates both vertical extrusion and horizontal pushing on the external sliding groove rod piece 4, compared with the prior art which directly uses the head 11 of the bolt 1 to vertically extrude the external sliding groove rod piece 4, the additional horizontal pushing of the present scheme can enhance the connection stability of the external sliding groove rod piece 4 and the external component 5 to a certain extent, that is, the fastening ability of the fixing structure is improved.

[0027] In this embodiment, two sliders 2 are distributed on both sides of the bolt 1 along the length direction of the strip-shaped hole 41, and the two sliders 2 on the same side are connected to the same rod group 3; the rod group 3 includes two X-shaped hinged struts 31, the proximal end of the strut 31 is hinged to the slider 2, and the distal end extends into the strip-shaped hole 41. Further, the strut 31 is Z-shaped, which is sequentially connected end to end by the upper horizontal rod 311, the vertical rod 312 and the lower horizontal rod 313, the proximal end of the upper horizontal rod 311 is hinged to the slider 2, and the lower horizontal rod 313 is located in the strip-shaped hole 41. During the process of the bolt 1 penetrating into the external member 5, the two ends of the lower horizontal rod 313 are simultaneously close to the hole wall of the strip-shaped hole 41. The end of the slider 2 away from the arc surface 21 forms a mounting table 22, and the mounting table 22 is hinged to the proximal end of the strut 31. Since the mounting table 22 is located above the external sliding groove rod 4, in order to enable the distal end of the strut 31 to extend into the strip-shaped hole 41, the strut 31 is arranged in a Z shape. The rod group 3 includes two struts 31, the middle part of the two struts 31 is hinged and X-shaped. During the process of the bolt 1 penetrating into the external member 5, the head 11 generates a pushing force obliquely downward on the slider 2, and the horizontal component of the pressure force makes the slider 2 drive the proximal end of the strut 31 to gradually move away from the bolt 1, and the distal end of the two struts 31 moves reversely and is squeezed against the hole wall of the strip-shaped hole 41 under the action.

[0028] In this embodiment, the two ends of the lower horizontal rod 313 are hinged to the patch 6. By arranging the patch 6, the contact area between the distal end of the strut 31 and the strip-shaped hole 41 can be increased, so that the fit is more compact. The patch 6 moves with the strut 31, which can be tightly attached to the hole wall of the strip-shaped hole 41 to apply pressure, or can be separated from the hole wall of the strip-shaped hole 41 to release the fixation of the external sliding groove rod 4.

[0029] In this embodiment, the two struts 31 of the same rod group 3 are hinged through the hinge shaft 33; the fixing structure further includes a limiting sleeve rod 7, which includes a main ring 71 sleeved on the bolt 1 and a secondary ring 72 sleeved on the hinge shaft 33, and the main ring 71 and the secondary ring 72 are connected through a pull rod 73. By arranging the limiting rod sleeve 7, the distance between the main ring 71 and the secondary ring 72 is fixed by the pull rod 73, that is, the distance between the hinge point of the bolt 1 and the strut 31 is fixed, so that the distal end of the strut 31 can be ensured to be squeezed towards the hole wall of the strip-shaped hole 41 during the movement of the strut 31.

[0030] Embodiment 2

[0031] As Figure 3As shown, the second embodiment of the fixing structure of the slide bar of the present invention is basically the same as that of embodiment 1, except that: in this embodiment, a slider 2 is distributed on each side of the bolt 1 along the width direction of the strip hole 41, and a rod group 3 is distributed on each side of the bolt 1 along the length direction of the strip hole 41; the rod group 3 includes two X-shaped hinged support rods 31, the proximal end of the support rod 31 is hinged to the slider 2, and the distal end extends into the strip hole 41. A mounting platform 22 is formed at the end of the slider 2 away from the arc surface 21, and the mounting platform 22 is hinged to the proximal end of the support rod 31. Since the mounting platform 22 is located above the external slide bar 4, the support rod 31 is set in a Z-shape so that the distal end of the support rod 31 can extend into the strip hole 41. The rod assembly 3 includes two struts 31, which are hinged at the middle and form an X shape. As the bolt 1 is inserted into the external component 5, the head 11 pushes the slider 2 obliquely downward. The lateral component of this pressure causes the slider 2 to drive the proximal end of the strut 31 to gradually move away from the bolt 1. Under this action, the distal ends of the two struts 31 will move in opposite directions and squeeze against the wall of the strip hole 41.

[0032] Example 3

[0033] like Figure 4 and Figure 5 As shown, the third embodiment of the fixing structure of the sliding rod of the present invention is basically the same as that of embodiment 1, except that: in this embodiment, a slider 2 is distributed on each side of the bolt 1 along the length direction of the strip hole 41, and each slider 2 is hinged to a rod assembly 3; the rod assembly 3 includes two connecting rods 32 and two X-shaped hinged support rods 31. The proximal end of the connecting rod 32 is hinged to the slider 2, and the distal end is hinged to the proximal end of the support rod 31. The distal end of the support rod 31 extends into the strip hole 41. Further, the connecting rod 32 is configured as a folded rod, and the support rod 31 is located in the strip hole 41. As the bolt 1 penetrates into the external component 5, both ends of the support rod 31 simultaneously approach the hole wall of the strip hole 41. Furthermore, both ends of the support rod 31 are hinged with patches 6. A mounting platform 22 is formed at the end of the slider 2 away from the arc surface 21. The mounting platform 22 is hinged to the proximal end of the support rod 31. Since the mounting platform 22 is located above the external sliding groove rod 4, the connecting rod 32 is configured as a folded rod so that the distal end of the support rod 31 can extend into the slotted hole 41. The rod assembly 3 includes two connecting rods 32 and two support rods 31. During the process of the bolt 1 penetrating the external component 5, the head 11 exerts a downward oblique pressure on the slider 2. The lateral component of this pressure causes the slider 2 to drive the distal end of the connecting rod 32 to gradually move away from the bolt 1. Since the distal end of the connecting rod 32 is hinged to the proximal end of the support rod 31, and the two support rods 31 are hinged in the middle in an X-shape, the distal ends of the two support rods 31 will move in opposite directions under this action and squeeze against the hole wall of the slotted hole 41. By setting the patch 6, the contact area between the distal end of the support rod 31 and the slotted hole 41 can be increased, thereby making the fit tighter.

[0034] Although the present application has been described in connection with the preferred embodiment thereof with reference to the drawings, it is not to be limited to the details described therein but can be modified in various ways which are within the scope of the present application and can be apparent to those skilled in the art without departing from the spirit of the application.
