Description

Technical Field

[0001] This utility model relates to the field of fixing device technology, and in particular to a hoop and clamp. Background Technology

[0002] Clamping clamps, characterized by their torsional resistance, pressure resistance, and balanced torsional torque, are widely used in various industries. Existing clamping clamps typically include a clamp housing, a fastening plate, a gear, and a fixing block. One end of the fastening plate is fixedly connected to the clamp housing, while the other end movably passes through it. The gear is rotatably mounted on the clamp housing and engages with a toothed slot on the fastening plate. When the gear rotates, it drives the fastening plate to tighten or loosen. The fixing block is movably mounted on the clamp and is used to lock or unlock the relative position of the gear and the clamp housing. Since the fastening plate, gear, and fixing block all need to be mounted on the clamp housing, the structural stability of the clamp housing is crucial for both manufacturers and users.

[0003] Existing hoop housings typically consist of an upper hoop and a lower hoop. The upper hoop has several locking tabs, and the lower hoop has several locking holes. The locking tabs and holes are inserted one-to-one in the vertical direction. The locking tabs are then bent to engage the upper and lower hoops, creating a space between them to accommodate fastening plates and gears. Because the locking tabs and holes are inserted vertically, the relative position of the upper and lower hoops in this direction is sufficiently stable. However, the constraint effect in other directions is weak, resulting in poor structural stability of the hoop housing.

[0004] Therefore, there is an urgent need for a hoop and clamp to solve the above problems. Utility Model Content

[0046] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0047] This embodiment provides a clamp that can be used to connect two pipes together, specifically to connect the corrugated pipe and the air outlet of a range hood together.

[0048] Please refer to Figures 1 to 4 The clamp includes a clamp housing 10, a rotating shaft 20, a gear 30, a fastening plate 40, and a locking element 50. The clamp housing 10 has a through hole 101 and a gear shaft hole 102 communicating with the through hole 101. The rotating shaft 20 is rotatably inserted through the gear shaft hole 102. The first end of the fastening plate 40 is fixed to the clamp housing seat 12, and the second end of the fastening plate 40 passes through the through hole 101. The fastening plate 40 has several toothed grooves 401, which are evenly spaced along the length of the fastening plate 40. The gear 30 is fixed to the rotating shaft 20 and located within the through hole 101. The gear 30 is always meshed with the toothed grooves 401, and the rotation of the gear 30 can tighten or loosen the fastening plate 40. The locking element 50 is movably connected to the clamp housing 10 and is used to lock or unlock the relative position of the gear 30 and the clamp housing 10. Specifically, the locking member 50 is movable relative to the hoop 10 and has a locked position and an unlocked position. When the locking member 50 is in the locked position, the locking member 50 locks the relative position of the gear 30 and the hoop 10, and the gear 30 cannot rotate at this time. When the locking member 50 is in the unlocked position, the gear 30 can be rotated, which can drive the fastening plate 40 to tighten or loosen.

[0049] Optionally, the clamp also includes a connector 60 fixedly connected to the rotating shaft 20. The connector 60 is located outside the through hole 101. The connector 60 is used to connect a torque wrench, and rotating the connector 60 by the torque wrench can drive the rotating shaft 20 to rotate, thereby driving the gear 30 to rotate. Specifically, the connector 60 may be provided with a insertion groove 601, through which the torque wrench is inserted and engaged. The insertion groove 601 can be a slotted groove for engaging with a slotted torque wrench, a star-shaped groove for engaging with a star-shaped torque wrench, a cross-shaped groove for engaging with a cross-shaped torque wrench, or an internal hexagonal groove for engaging with an internal hexagonal torque wrench, etc. The torque wrench can be an electric torque wrench or a manual torque wrench. In other embodiments, the insertion groove 601 can also be replaced by an insertion protrusion.

[0050] The manner in which the locking member 50 can move relative to the hoop 10 can be determined according to actual needs. For example, the locking member 50 can be directly and movably connected to the hoop 10, or it can be indirectly and movably connected to the hoop 10. In this embodiment, an example is given of a scheme in which the locking member 50 moves indirectly relative to the hoop 10.

[0051] Specifically, please refer to Figures 3 to 5 In this embodiment, the locking member 50 is fixed to the rotating shaft 20, and the hoop 10 is also provided with a limiting hole 103 communicating with the through hole 101. The rotating shaft 20 passes through the limiting hole 103. Both the limiting hole 103 and the locking member 50 are regular polygons with the same number of sides. The rotating shaft 20 can also slide relative to the hoop 10 along the axial direction of the rotating shaft 20, so that the locking member 50 can be inserted into the limiting hole 103 and restrict the rotation of the rotating shaft 20, or the locking member 50 can be separated from the limiting hole 103. Specifically, the shape of the limiting hole 103 is adapted to the shape of the locking member 50, and the size of the limiting hole 103 is adapted to the size of the locking member 50. When the locking member 50 is in the locked position, it is inserted into the limiting hole 103 and its rotation is restricted by the hoop 10, thereby restricting the rotation of the shaft 20 and the gear 30 to lock the relative position of the gear 30 and the hoop 10. When the locking member 50 is in the unlocked position, it disengages from the limiting hole 103 and can rotate synchronously with the gear 30. In the clamp provided in this embodiment, the locking member 50 and the gear 39 are set on the same shaft 20. By controlling the connecting member 60, the rotation of the shaft 20 or its sliding relative to the hoop 10 can be controlled simultaneously. Therefore, during the clamping operation, only the connecting member 60 needs to be controlled, making the operation simple and convenient and effectively improving the operating efficiency of the clamp.

[0052] In this embodiment, both the limiting hole 103 and the locking member 50 are exemplarily hexagonal. In other embodiments, the limiting hole 103 and the locking member 50 can also be octagonal, decagonal, etc. During the clamping operation, at most the rotating shaft 20 needs to be rotated by the central angle corresponding to one side of the regular polygon to align the locking member 50 and the limiting hole 103, facilitating their insertion and engagement; and as the number of sides of the regular polygon increases, the angle of the central angle decreases.

[0053] Preferably, the outer diameter of the rotating shaft 20 is equal to the inner diameter of the inscribed circle of the regular polygon. With this configuration, when the locking member 50 is in the unlocked position, the rotating shaft 20 can contact each edge point of the limiting hole 103, which can ensure that the hoop 10 stably supports the rotating shaft 20 and prevent the rotating shaft 20 from skipping teeth due to unstable support when rotating.

[0054] As an alternative, the limit switch can be movably connected to the housing 10. For example, the locking member 50 can be rotatably or slidably connected to the housing 10, and the locking member 50 can engage with or disengage from the tooth groove of the gear 30. When the locking member 50 is in the locked position, the locking member 50 is inserted into the tooth groove of the gear 30 and can restrict the rotation of the gear 30 relative to the housing 10. When the locking member 50 is in the unlocked position, the gear 30 can rotate freely relative to the housing 10.

[0055] Alternatively, please refer to Figure 3 and Figure 4 The clamp also includes an elastic element 70, which is configured to ensure that the locking member 50 always has a tendency to engage with the limiting hole 103. With this configuration, when the clamp is tightened, the locking member 50 can move from the unlocked position to the locked position under the action of the elastic element 70, so that the locking member 50 can be stably maintained in the locked position without external force, thereby ensuring the clamping effect of the clamp is stable. In this embodiment, the elastic element 70 is exemplarily provided as a compression spring. A spring seat 80 is also fixed on the rotating shaft 20. The two ends of the elastic element 70 abut against the clamp housing 10 and the spring seat 80, respectively. The elastic element 70 is located outside the through hole 101, and the elastic element 70 and the gear 30 are located on both sides of the locking member 50, respectively. In other embodiments, the elastic element 70 can also be a tension spring or a disc spring, etc.

[0056] Existing hoop housings typically consist of an upper hoop and a lower hoop. The upper hoop has several locking tabs, and the lower hoop has several locking holes. The locking tabs and holes are inserted one-to-one in the vertical direction. The locking tabs are then bent to engage the upper and lower hoops, creating a space between them to accommodate fastening plates and gears. Because the locking tabs and holes are inserted vertically, the relative position of the upper and lower hoops in this direction is sufficiently stable. However, the constraint effect in other directions is weak, resulting in poor structural stability of the hoop housing.

[0057] For this, please refer to Figure 2 , Figures 6 to 10 In this embodiment, the hoop 10 includes a hoop body, a plurality of first snap-fit ​​structures, and a plurality of second snap-fit ​​structures. The hoop body includes structures along a first direction (e.g., ...). Figure 2 The hoop cover 11 and hoop seat 12 are fastened together (in the direction indicated by arrow ab in the image), and the hoop cover 11 and hoop seat 12 are arranged to surround the second direction (as shown by arrow ab in the image). Figure 2 The through hole 101 extends in the direction indicated by the cd arrow in the image, and along a third direction (such as...). Figure 2 The gear shaft hole 102 extends in the direction indicated by the arrow ef in the diagram. The through hole 101 communicates with the gear shaft hole 102, and the first direction, the second direction, and the third direction are perpendicular to each other. The first snap-fit ​​structure includes a first snap-fit ​​hole 21 and a first snap-fit ​​piece 22. The first snap-fit ​​hole 21 is disposed in one of the hoop cover 11 and the hoop seat 12, and the first snap-fit ​​hole 21 extends along the first direction. The first snap-fit ​​piece 22 is disposed in the other of the hoop cover 11 and the hoop seat 12, and the first snap-fit ​​piece 22 snaps into the first snap-fit ​​hole 21. The second snap-fit ​​structure includes a second snap-fit ​​hole 31 and a second snap-fit ​​piece 32. The second snap-fit ​​hole 31 is disposed in one of the hoop cover 11 and the hoop seat 12, and the second snap-fit ​​hole 31 extends along the third direction. The second snap-fit ​​piece 32 is disposed in the other of the hoop cover 11 and the hoop seat 12, and the second snap-fit ​​piece 32 snaps into the second snap-fit ​​hole 31. With this configuration, the hoop cover 11 and the hoop seat 12 can be fixed together in the first direction by the first snap-fit ​​structure, and the first snap-fit ​​piece 22 can be limited by the side wall of the first snap-fit ​​hole 21. It can also provide a certain constraint effect on the hoop cover 11 and the hoop seat 12 in the second and third directions. The hoop cover 11 and the hoop seat 12 can be fixed together in the third direction by the second snap-fit ​​structure, and the second snap-fit ​​piece 32 can be limited by the side wall of the second snap-fit ​​hole 31. It can also provide a certain constraint effect on the hoop cover 11 and the hoop seat 12 in the first and second directions. In this way, the hoop cover 11 and the hoop seat 12 can be stably connected together, thereby ensuring the structural stability of the hoop 10.

[0058] In this embodiment, an exemplary scheme is provided in which the first snap-fit ​​hole 21 of each first snap-fit ​​structure is provided in the hoop cover 11, and the first snap-fit ​​piece 22 of each first snap-fit ​​structure is provided in the hoop seat 12; and in which the second snap-fit ​​piece 32 of each second snap-fit ​​structure is provided in the hoop cover 11, and the second snap-fit ​​hole 31 of each second snap-fit ​​structure is provided in the hoop seat 12. In other embodiments, each first snap-fit ​​piece 22 of the first snap-fit ​​structure may be provided with a housing cover 11, and each first snap-fit ​​hole 21 of the first snap-fit ​​structure may be provided with a housing seat 12; or, a portion of the first snap-fit ​​pieces 22 of the first snap-fit ​​structure may be provided with a housing cover 11 and a first snap-fit ​​hole 21 may be provided with a housing seat 12, while the other portion of the first snap-fit ​​structure may be provided with a housing cover 11 and a first snap-fit ​​piece 22 may be provided with a housing seat 12; or, each second snap-fit ​​hole 31 of the second snap-fit ​​structure may be provided with a housing cover 11 and a second snap-fit ​​piece 32 may be provided with a housing seat 12; or, a portion of the second snap-fit ​​pieces 32 of the second snap-fit ​​structure may be provided with a housing cover 11 and a second snap-fit ​​hole 31 may be provided with a housing seat 12, while the other portion of the second snap-fit ​​structure may be provided with a housing cover 11 and a second snap-fit ​​piece 32 may be provided with a housing seat 12.

[0059] Alternatively, please refer to Figure 9 The hoop cover 11 includes a first cover side plate 111 and a second cover side plate 112 spaced apart along a third direction, and a top plate 113 connected between the first cover side plate 111 and the second cover side plate 112; the hoop seat 12 includes a first seat side plate 121 and a second seat side plate 122 spaced apart along a third direction, and a bottom plate 123 connected between the first seat side plate 121 and the second seat side plate 122. The bottom plate 123 and the top plate 113 are parallel and spaced apart along a first direction. The first cover side plate 111 and the first seat side plate 121 are staggered along the first direction, and the second cover side plate 112 and the second seat side plate 122 are staggered along the first direction. The gear shaft hole 102 includes a first hole and a second hole coaxially arranged. The first hole is formed by the first cover side plate 111 and the first seat side plate 121, and the second hole is formed by the second cover side plate 112 and the second seat side plate 122. This configuration further enhances the structural strength of the hoop 10 by staggering the first cover side plate 111 and the first seat side plate 121 along the first direction, and by staggering the second cover side plate 112 and the second seat side plate 122 along the first direction. In addition, the first seat side plate 121 and the second seat side plate 122 together form the first hole, and the second cover side plate 112 and the second seat side plate 122 together form the second hole, so that the rotating shaft 20 is supported by both the two cover side plates and the two seat side plates, ensuring the stability of the support for the rotating shaft 20.

[0060] Specifically, please refer to Figure 8 and Figure 9 In this embodiment, the first cover side plate 111 is provided with a first U-shaped hole 114, and the first seat side plate 121 is provided with a second U-shaped hole 124. The openings of the first U-shaped hole 114 and the second U-shaped hole 124 are opposite to each other, and the first U-shaped hole 114 and the second U-shaped hole 124 are staggered along a first direction, forming a first hole. The second cover side plate 112 is provided with a third U-shaped hole 115, and the second seat side plate 122 is provided with a fourth U-shaped hole 125. The openings of the third U-shaped hole 115 and the fourth U-shaped hole 125 are opposite to each other, and the third U-shaped hole 115 and the fourth U-shaped hole 125 are staggered along a first direction, forming a second hole. This arrangement facilitates the assembly of the rotating shaft 20 and other components such as the gear 30 mounted on the rotating shaft 20 into a whole, and then assembling the whole with the hoop cover 11 and the hoop seat 12.

[0061] In this embodiment, the first hole is a circular hole, and the inner diameter of the circular hole matches the outer diameter of the rotating shaft 20; the second hole and the limiting hole 103 are combined into one hole, which is a regular polygonal hole. In other embodiments, the second hole and the limiting hole 103 can also be provided separately.

[0062] Alternatively, please refer to Figure 2 and Figure 10 Along a third direction, the first seat side plate 121 and the second seat side plate 122 are both located between the first cover side plate 111 and the second cover side plate 112, and both the first seat side plate 121 and the second seat side plate 122 abut against the top plate 113 along the first direction.
