Description

Technical Field

[0001] The invention relates to the technical field of interior decoration, in particular to a curved surface keel connector. Background Art

[0002] The curved surface modeling keel connector is a component specially used to connect and fix the keel in the curved surface structure. This connector is usually used in architecture and interior decoration, especially in those design projects that need to create complex curves or streamlined appearances. The curved surface keel is usually composed of a main keel and a secondary keel. The main keel is usually the thickest part of the curved surface keel system, which is used to support the structural stability of the entire system. The secondary keel is a smaller keel connected to the main keel and is used to connect multiple main keels. The hanger is used to connect the keel with other structural components (such as the main structure of the building).

[0003] However, there are the following defects in the process of connecting the curved keel to the roof:

[0004] 1. Since the curved keel is curved, when the curved keel is hoisted on the roof through a hanger, the hanger needs to be cut according to the distance from the curved keel to the roof so that the hanger can adapt to the distance from the curved keel to the roof. In this way, the distance between the curved keel and the roof needs to be measured and then each hanger needs to be cut. If the measurement is inaccurate or the cutting is improper, or if it is found during the construction process or later that the height of the curved keel needs to be adjusted, it will be difficult to adjust the hanger after cutting, and it may need to be re-cut or replaced, resulting in material waste and increasing project time and cost.

[0005] 2. The curved keel is fixedly connected to the hanger by bolts, but the bolt connection needs to be tightened with tools, which requires high skills of the construction workers. Once the bolt connection is tightened, adjustment may require the removal and reinstallation of the bolts, which is relatively time-consuming.

[0006] Therefore, the present invention proposes a curved keel connector to compensate for and improve the deficiencies of the prior art. Summary of the invention

[0007] In view of the above problems, the invention provides a curved keel connector, which can effectively solve the problems of waste of materials in the prior art due to the cutting of the suspension rod and time-consuming traditional bolt connection of the keel. In order to achieve the above purpose, the embodiment of the present application provides the following technical solutions:

[0008] The invention discloses a curved keel connector, comprising a curved keel body, a plurality of suspension rods are arranged on the top of the curved keel body, an adjustment mechanism is arranged at the bottom of the suspension rods, a quick connection mechanism is arranged on the curved keel body, and a positioning mechanism is arranged on the top of the suspension rods.

[0009] The adjustment mechanism includes a sliding rod that is slidably sleeved in the cavity at the bottom of the suspension rod, and the sliding rod is symmetrically provided with receiving grooves on the outside. An L-shaped shift block is rotatably connected inside each of the receiving grooves, and an inclined surface is provided on the side of the horizontal section of the L-shaped shift block. A plurality of positioning holes are symmetrically provided on the outside of the suspension rod, and the plurality of positioning holes are vertically arranged along the suspension rod. A limiting component is provided on the outside of the suspension rod to prevent the sliding rod from rotating.

[0010] The quick connection mechanism includes a C-shaped connector fixedly connected to the bottom of the sliding rod, a fixing plate fixedly connected to one side of the notch of the C-shaped connector, a shell fixedly connected to the outer side of the fixing plate, a bottom cavity is opened at the bottom of the shell, a sliding block is slidably connected in the bottom cavity, and an extrusion assembly is arranged between the suspension rod and the mounting plate.

[0011] Furthermore, the limiting assembly includes a pressure rod symmetrically connected to the outside of the suspension rod, one end of the pressure rod is fixedly connected to an insert block, the other end of the pressure rod is fixedly connected to a first spring, and the first spring is fixedly connected to the outside of the suspension rod away from one end of the pressure rod.

[0012] Furthermore, the limiting component also includes a sliding groove vertically and symmetrically opened on the outside of the sliding rod, and the two insert blocks are respectively embedded in the sliding groove.

[0013] Furthermore, the quick connection mechanism also includes a pull rod that slides vertically through the shell, one end of the pull rod is fixedly connected to the top of the slider, the other end of the pull rod is rotatably connected to a connecting rod, the connecting rod is rotatably connected to a rotating rod away from one end of the pull rod, one end of the rotating rod is rotatably connected to the side of the fixed plate, and a second spring is sleeved on the outside of the pull rod, and the second spring is located inside the bottom cavity.

[0014] Furthermore, the extrusion assembly includes grooves symmetrically opened on the side of the C-shaped connector, and a moving rod is horizontally slidably connected in each groove. The outside of the C-shaped connector is symmetrically arranged with tension springs, one end of the tension spring is fixedly connected to the outside of the C-shaped connector, and the other end of the tension spring is fixedly connected to the moving rod.

[0015] Furthermore, the positioning mechanism includes a protrusion fixedly connected to the top of the suspension rod, a mounting plate is slidably sleeved on the outer side of the protrusion, a guide groove is provided at the bottom of the mounting plate, the longitudinal section of the guide groove is convex-shaped, a movable bin is horizontally provided on the protrusion, and T-shaped moving blocks are symmetrically slidably connected at both ends of the movable bin.

[0016] Furthermore, a third spring is fixedly connected between the two moving blocks, and a clamping block is fixedly connected to one end of each moving block away from the third spring.

[0017] Furthermore, a plurality of limit blocks are equidistantly and symmetrically fixedly connected to the side surface of the guide groove, and the clamping block is clamped in the area between two adjacent limit blocks.

[0018] Beneficial effects:

[0019] 1. By providing an adjustment mechanism, when the curved keel body is hoisted to the roof, the slide rod is pulled to move the slide rod along the suspension rod, and the total length of the slide rod and the suspension rod can be adjusted according to the distance from the curved keel body to the roof. Different distance requirements can be flexibly adapted within a certain range, and there is no need to change the suspension rod once it is cut, which reduces the waste of materials and the consumption of construction time, thereby reducing the construction cost. At the same time, the method of adjusting the total length of the slide rod and the suspension rod is relatively faster than cutting the suspension rod, and there is no need for cutting operations and subsequent cleaning work, which saves construction time.

[0020] 2. By providing a quick connection mechanism, when installing the curved keel body, the curved keel body is directly placed into the C-type connector, and then the curved keel body is blocked in the C-type connector by the falling slider. Compared with the use of bolt connection, this does not require the use of tools for complicated tightening operations, can quickly complete the connection, improve installation efficiency, and has relatively low skill requirements for construction personnel. Professional bolt tightening knowledge and skills are not required, which reduces the difficulty of construction. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention will be further described below in conjunction with the embodiments.

A plurality of positioning holes 35 are symmetrically provided on the outside of the suspension rod 2, and the plurality of positioning holes 35 are vertically arranged along the suspension rod 2. A limiting component 36 is provided on the outside of the suspension rod 2 to prevent the sliding rod 31 from rotating.

[0038] The limiting assembly 36 includes a pressure rod 363 symmetrically connected to the outside of the suspension rod 2, one end of the pressure rod 363 is fixedly connected to the plug block 362, and the other end of the pressure rod 363 is fixedly connected to the first spring 364, and the first spring 364 is fixedly connected to the outside of the suspension rod 2 at one end away from the pressure rod 363.

[0039] The limiting component 36 further includes a slide groove 361 vertically and symmetrically opened on the outside of the slide rod 31 , and two insert blocks 362 are respectively embedded in the slide groove 361 .

[0040] When the total length of the suspension rod 2 and the sliding rod 31 needs to be adjusted during specific operation, first, press the pressure rod 363 so that the pressure rod 363 drives the plug block 362 to disengage from the sliding groove 361, then rotate the suspension rod 2 horizontally so that the inclined surface 34 of the L-shaped shift block 33 disengages from the positioning hole 35, and then pull the sliding rod 31 to slide out from the bottom of the suspension rod 2, so that the total length of the suspension rod 2 and the sliding rod 31 can be extended. When the appropriate length is adjusted, the suspension rod 2 is rotated horizontally in the opposite direction so that the L-shaped shift block 33 enters the positioning hole 35, so that the position of the sliding rod 31 is fixed by the L-shaped shift block 33, at this time, the plug block 362 is synchronously rotated to the outside of the sliding groove 361, and finally the pressure rod 363 is released, and the pressure rod 363 is pushed to rotate under the elastic force of the first spring 364, so that the plug block 362 re-enters the sliding groove 361, and the horizontal rotation of the suspension rod 2 is limited by the plug block 362 entering the sliding groove 361.

[0043] During specific operation, after the total length of the suspension rod 2 and the sliding rod 31 is adjusted, the curved keel body 1 is placed into the C-shaped connecting piece 41, and the notch of the C-shaped connecting piece 41 is blocked by the downward sliding block 44, thereby fixing the curved keel body 1 in the C-shaped connecting piece 41. When the curved keel body 1 needs to be adjusted, the rotating rod 48 is rotated upward, and the rotating rod 48 drives the pull rod 46 to move upward through the connecting rod 49. The upward moving pull rod 46 drives the slider 44 to move upward synchronously, so that the notch of the C-shaped connecting piece 41 can be in an open state, so that the curved keel body 1 can be removed from the C-shaped connecting piece 41, thereby adjusting the position of the curved keel body 1.

[0044] See also Figure 5 and Fig.11 The extrusion assembly 5 includes grooves 52 symmetrically opened on the side of the C-shaped connecting member 41, and a moving rod 51 is horizontally slidably connected in each groove 52. A tension spring 53 is symmetrically arranged on the outside of the C-shaped connecting member 41, one end of the tension spring 53 is fixedly connected to the outside of the C-shaped connecting member 41, and the other end of the tension spring 53 is fixedly connected to the moving rod 51.

[0045] During specific operation, after the curved keel body 1 is placed into the C-shaped connector 41, the two movable rods 51 are respectively fitted onto the arc surface of the curved keel body 1 under the tension of the tension spring 53, and the two movable rods 51 firmly squeeze and fix the curved keel body 1 inside the C-shaped connector 41, thereby improving the fit between the curved keel body 1 and the C-shaped connector 41 and reducing the degree of shaking of the curved keel body 1 inside the C-shaped connector 41.

[0046] See also Figure 7 and Fig.10 The positioning mechanism 6 includes a protrusion 61 fixedly connected to the top of the suspension rod 2, a mounting plate 68 is slidably sleeved on the outer side of the protrusion 61, a guide groove 62 is opened at the bottom of the mounting plate 68, and the longitudinal section of the guide groove 62 is convex-shaped. The protrusion 61 is horizontally opened with a movable bin 63, and T-shaped moving blocks 64 are symmetrically slidably connected at both ends of the movable bin 63.

[0047] A third spring 65 is fixedly connected between the two moving blocks 64 , and a clamping block 67 is fixedly connected to one end of each moving block 64 away from the third spring 65 .

[0048] A plurality of limit blocks 66 are symmetrically and equidistantly fixedly connected to the side surface of the guide groove 62 , and a clamping block 67 is clamped in the area between two adjacent limit blocks 66 .

[0049] During specific operation, after the mounting plate 68 is fixed to the roof using expansion bolts, multiple hangers 2 are inserted into the guide groove 62 at the bottom of the mounting plate 68, and the protrusion 61 is used to snap into the guide groove 62, and then the hanger 2 is pushed to move along the guide groove 62. After the hanger 2 is moved to a position suitable for connecting the curved keel body 1, the total length of the hanger 2 and the slide rod 31 can be adjusted. In the process of moving the hanger 2, the elastic force of the third spring 65 pushes the block 67 at one end of the moving block 64 to snap into the gap of the limit block 66, and the mutual snap connection between the block 67 and the limit block 66 allows the hanger 2 to be fixed in position after moving.

[0050] The overall working process:

[0051] The mounting plate 68 is fixedly connected to the roof by expansion bolts. After the mounting plate 68 is fixedly installed on the roof, multiple hangers 2 are inserted into the guide groove 62 at the bottom of the mounting plate 68, and the protrusion 61 is used to snap into the guide groove 62, and then the hanger 2 is pushed to move along the guide groove 62. In the process of moving the hanger 2, the limit block 66 at one end of the moving block 64 is pushed by the elastic force of the third spring 65 to snap into the gap of the limit block 66. The mutual snap connection between the block 67 and the limit block 66 allows the hanger 2 to fix its position after moving. When the total length of the hanger 2 and the slide bar 31 needs to be adjusted, the slide bar 31 is pulled out from the bottom of the hanger 2 to extend the total length of the hanger 2 and the slide bar 31. When it is adjusted to the appropriate length, the hanger 2 is rotated horizontally in the opposite direction so that the L-shaped block 33 enters the positioning The L-shaped shift block 33 is used to fix the position of the slide bar 31. At this time, the plug block 362 is synchronously rotated to the outside of the slide groove 361. Finally, the pressure rod 363 is released, and the pressure rod 363 is pushed to rotate under the elastic force of the first spring 364, so that the plug block 362 re-enters the slide groove 361. The plug block 362 entering the slide groove 361 is used to limit the horizontal rotation of the suspension rod 2. When the position of the curved keel body 1 needs to be adjusted, the rotating rod 48 is rotated upward. The rotating rod 48 drives the pull rod 46 to move upward through the connecting rod 49. The upward moving pull rod 46 drives the slider 44 to move upward synchronously. In this way, the notch of the C-shaped connecting piece 41 can be opened, so that the curved keel body 1 can be removed from the C-shaped connecting piece 41, thereby adjusting the position of the curved keel body 1.
