[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 Figure 8 is the first embodiment of the utility model, which provides a quick-disassembly and assembly device for fastening the tension rods, which solves the problem that the time required for disassembly and assembly of the tension screw rods and the matching nuts affects the construction period, and includes an insertion component 100 and a rotation component 200.

[0033] Specifically, the insertion assembly 100 includes a tie rod 101 and an extrusion piece 102 . The extrusion piece 102 is movably connected to the outside of the tie rod 101 . The extrusion piece 102 moves along the outside of the tie rod 101 , and the number of the extrusion pieces 102 is set to be multiple.

[0034] Preferably, the number of the extrusion pieces 102 is set to two, and the extrusion pieces 102 are movably connected to the two sides of the tension rod 101 correspondingly, and the two groups of extrusion pieces 102 act simultaneously to reinforce the scissor wall.

[0035] Furthermore, the rotating component 200 includes a rotating member 201 and a limiting member 202. The rotating member 201 is arranged in the inner cavity of the extrusion member 102. The rotating member 201 rotates accordingly with the operation of the extrusion member 102. The limiting member 202 contacts and connects the extrusion member 102 and the rotating member 201, that is, the rotating member 201 rotates around the limiting member 202, and the two ends of the limiting member 202 are contacted and connected to the outer wall of the extrusion member 102, so that the horizontal position of the rotating member 201 remains stable.

[0036] When in use, the worker first selects a tie rod 101 of appropriate length, and then slots the tie rod 101 at the corresponding position according to the thickness of the wallboard and the thickness of the reinforcement material for the subsequent insertion of the extrusion piece 102. The extrusion piece 102 is passed through the outer wall of the tie rod 101 to contact the steel pipe, and then part of the extrusion piece 102 is inserted into the slot opened in the tie rod 101 for further extrusion.

[0037] Since the extrusion member 102 is in contact with the rotating member 201, when the extrusion member 102 descends, it will drive the rotating member 201 to rotate, causing the rotating member 201 to rotate clockwise, and the limiting member 202 is in contact with the inner side of the rotating member 201. Therefore, when the rotating member 201 rotates to a certain angle, the limiting member 202 is restricted from rotating, and part of the rotating member 201 continues to rotate as the extrusion member 102 descends.

[0038] When the extrusion piece 102 is completely inserted into the groove of the pull rod 101, the rotating piece 201 also stops rotating, thus fixing the extrusion piece 102. When an external force accidentally pushes the extrusion piece 102, the extrusion piece 102 maintains a relatively stable position. When the worker needs to remove the extrusion piece 102, he only needs to rotate the limiter 202, so that part of the rotating piece 201 contacts the limit, so that part of the rotating piece 201 rotates in the opposite direction, and then the extrusion piece 102 is released. The worker uses a hammer to lightly hit the extrusion piece 102, and the extrusion piece 102 can be unlocked, achieving the effect of quick installation and convenient disassembly.

[0039] In summary, the scissor wall can be quickly fastened by setting an insert component. The worker gently hammers the extrusion part with a hammer to make it drop, and it gets stuck when it drops to a certain distance. During the dropping process, the rotating component rotates synchronously, and the insert component is stuck for the second time while it drops, thereby realizing the fastening function. When it needs to be removed, just turn the rotating component and gently tap the bottom of the insert component, and the insert component will slowly rise, thereby achieving the effect of quick disassembly.

[0040] Example 2

[0041] Reference Figures 1 to 9 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment,

[0042] Specifically, the extrusion piece 102 includes a clamping jaw 102a, a stabilizing groove 102b and a plug plate 102c. The clamping jaw 102a is in contact with and connected to the outer side of the plug plate 102c, and a stabilizing groove 102b is installed on the outer side of the clamping jaw 102a. The plug plate 102c rises or falls along the stabilizing groove 102b. A rack 102c-1 is provided on one end of the outer side of the plug plate 102c close to the clamping jaw 102a, and the two ends of the plug plate 102c are unequal in size. The upper end of the plug plate 102c is larger than the bottom end, so that the plug plate 102c can be stuck during the descent process.

[0043] Furthermore, the rotating member 201 includes a gear 201a, a check block 201b and a connecting rod 201c. The connecting rod 201c movably connects the gear 201a and the clamp 102a, that is, the gear 201a rotates around the connecting rod 201c in the inner cavity of the clamp 102a, and the check block 201b is rotatably arranged on the inner side of the clamp 102a. The check block 201b is meshed and connected with the gear 201a. The rotation of the gear 201a drives the check block 201b to reciprocate at a small angle, and a limiting member 202 is penetrated through the inner wall of the check block 201b, and the check block 201b rotates around the limiting member 202.

[0044] Furthermore, the limiting member 202 includes a rotating shaft 202a, a baffle 202b and a blocking block 202c. The rotating shaft 202a is movably connected to the inner wall of the clamp 102a and can rotate around the center of the axis. A blocking block 202c is installed on the outer side of the rotating shaft 202a. When the check block 201b rotates a certain angle, it will contact the blocking block 202c, thereby rotating in the opposite direction, that is, resetting. The baffle 202b is fixedly arranged on the outer side of the rotating shaft 202a, and the baffle 202b is located at both ends of the blocking block 202c. The baffle 202b is close to the two ends of the pull rod 101 and is provided with a torsion spring 202b-1. When the check block 201b rotates a certain angle, it will contact the blocking block 202c, thereby rotating in the opposite direction under the action of the torsion spring 202b-1, that is, resetting, thereby realizing the limiting of the gear 201a.

[0045] Preferably, the initial state of the torsion spring 202b-1 is a compressed state, and the check block 201b rotates a certain angle to make the compressed state of the torsion spring 202b-1 more and more tense. When the check block 201b moves in the opposite direction, the torsion spring 202b-1 will be reset to the initial state under the action of the compressed state. Due to the existence of the blocking block 202c, the torsion spring 202b-1 can only be reset to the initial state.

[0046] Furthermore, the limiting member 202 also includes a spring 202d, a telescopic rod 202e and a torsion block 202f. The spring 202d is installed at both ends of the rotating shaft 202a, and the end of the spring 202d away from the rotating shaft 202a is fixedly connected to the torsion block 202f. When the torsion block 202f moves, the spring 202d is telescoped, and the telescopic rod 202e is installed at the bottom end of the torsion block 202f. The movement of the torsion block 202f can drive the telescopic rod 202e to move. The other end of the telescopic rod 202e is slidably connected to the inner cavity of the rotating shaft 202a. When the torsion block 202f moves outward, the telescopic rod 202e also moves outward, that is, it slides in the inner cavity of the rotating shaft 202a.

[0047] Furthermore, a block 202e-1 is provided on the outside of the telescopic rod 202e, and there are multiple blocks 202e-1. The block 202e-1 is installed at one end of the telescopic rod 202e away from the torsion block 202f, that is, the block 202e-1 is located in the inner cavity of the rotating shaft 202a.

[0048] Furthermore, a slide groove 202a-1 is provided on the inner wall of the rotating shaft 202a, and the slide groove 202a-1 is in contact with the clamping block 202e-1, so that the telescopic rod 202e slides on the inner wall of the rotating shaft 202a through the clamping block 202e-1.

[0049] Furthermore, an insertion groove 101 a is formed through the outer side of the tie rod 101 , and the insertion groove 101 a is in contact with the inserting plate 102 c .

[0050] Furthermore, a rotating block 201b-1 is provided on the inner wall of the check block 201b, and the rotating block 201b-1 abuts against the blocking block 202c. In the initial state, one end of the rotating block 201b-1 abuts against the outer end of the blocking block 202c, and when the rotating block 201b-1 rotates with the check block 201b, it rotates to a certain angle and abuts against the other end of the blocking block 202c.

[0051] Furthermore, a protrusion is provided on the outer side of the twist block 202f, and the twist block 202f is clamped with the outer wall of the clamping jaw 102a.

[0052] When in use, the worker first selects a tie rod 101 of appropriate length, and then opens an insertion slot 101a at the corresponding position of the tie rod 101 according to the thickness of the wallboard and the thickness of the reinforcement material. When the reinforcement function is needed, the plug plate 102c is inserted. First, the clamping claw 102a passes through the outer wall of the tie rod 101 so that it contacts the steel pipe, and then the plug plate 102c is inserted into the insertion slot 101a opened in the tie rod 101. Then the worker uses a hammer to repeatedly and gently tap the top of the plug plate 102c, so that the plug plate 102c slowly descends until the outer side of the plug plate 102c is stuck in the inner wall of the insertion slot 101a.

[0053] Since a rack 102c-1 is provided at one end of the outer side of the plug plate 102c, the rack 102c-1 is meshed with the gear 201a. When the plug plate 102c descends along the insertion slot 101a, the rack 102c-1 on the plug plate 102c descends and causes the gear 201a to rotate clockwise, and the check block 201b is located at the upper end of the outer side of the gear 201a. Whenever the gear 201a rotates, the check block 201b is also pushed to rotate. When the gear 201a stops rotating, the check block 201b is reset due to the action of the torsion spring 202b-1. Therefore, when the plug plate 102c stops descending, the gear 201a stops rotating, and the check block 201b is reset to jam the gear 201a.

[0054] Due to the rotating block 201b-1 on the inner wall of the check block 201b, the torsion spring 202b-1 is reset to the initial state, and the top of the rotating block 201b-1 contacts the top of the blocking block 202c. When the plug plate 102c is accidentally touched, the plug plate 102c is easy to loosen, that is, the plug plate 102c is easy to be pulled out. When the plug plate 102c rises, the gear 201a rotates counterclockwise, and then the gear 201a drives the check block 201b to rotate counterclockwise, but because the top of the rotating block 201b-1 contacts the top of the blocking block 202c, the check block 201b cannot rotate counterclockwise, and then the gear 201a cannot rotate counterclockwise, that is, the plug plate 102c cannot be easily pulled out, thereby achieving the effect that the plug plate 102c cannot be easily pulled out even if it is accidentally touched.

[0055] When the worker needs to pull out the plug plate 102c, he first pulls out the torsion block 202f and rotates it clockwise by a certain angle, so that the rotating shaft 202a rotates clockwise synchronously, and the blocking block 202c on the outside of the rotating shaft 202a rotates with the rotating shaft 202a. At this time, the rotating block 201b-1 on the inner wall of the check block 201b loses the state of abutting against the blocking block 202c, and the torsion spring 202b-1 drives the check block 201b to rotate a certain angle. The rotation of the check block 201b causes the gear 201a to rotate synchronously, so that the plug plate 102c rises a certain distance, and a certain gap is generated between the plug plate 102c and the insertion slot 101a. Then the worker takes out the plug plate 102c, achieving the effect of quick disassembly and assembly.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
