Description

Technical Field

[0001] The utility model relates to the technical field of heating and ventilation ducts, in particular to a hanging bracket for heating and ventilation ducts. Background Art

[0002] The HVAC duct is a piping system used for ventilation and heating systems in buildings. The HVAC duct is generally fixed on the wall or ceiling. Excessive wind speed or changes in wind pressure in the HVAC duct may cause it to vibrate. During the installation process, the HVAC duct needs to be installed using hangers to reduce its vibration and ensure the stability and safety of the duct.

[0003] The prior art has a structure for installing the heating duct by means of a hanger, a fixing plate is provided under the hanger plate, the heating duct is installed under the fixing plate by means of two U-shaped supports, and is clamped by means of a clamping plate. However, when the two clamping plates of the prior art push the two upper ends of the U-shaped support outward, the opening of the U-shaped support will increase, and the contact area with the heating duct will decrease, so that the heating duct cannot be stably placed on the U-shaped support, and is prone to relatively large shaking, which increases the frequency of collision between the outer wall of the heating duct and the inner wall of the U-shaped support, and affects the service life of the heating duct. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a hanging bracket for a heating and ventilation duct.

[0005] The technical solution of this utility model is as follows:

[0006] A hanging bracket for a heating and ventilation duct is installed below a hanging rod connected to a wall surface, and comprises a clamping mechanism connected to the hanging rod through a connecting rod;

[0007] The clamping mechanism comprises a first clamping member and a second clamping member, the upper ends of the first clamping member and the second clamping member are hinged by a hinge shaft, and the lower ends are connected by a connecting member, and the opposite surfaces of the first clamping member and the second clamping member are both provided with clamping surfaces, which are adapted to the outer circumferential surface of the heating and ventilation duct;

[0008] Both ends of the connecting shaft extend outwardly with a first clamping piece and a second clamping piece, and are connected to the lower part of the connecting rod.

[0009] The hanger is installed on the inner wall of the ceiling or the wall top, and is used to support the installation of the entire hanging bracket. The heating ventilation duct is clamped by the first clamping member and the second clamping member, and is connected to the hanger through a connecting rod. The heating ventilation duct is hoisted, and the clamping surfaces of the first clamping member and the second clamping member are in close contact with the outer wall of the heating ventilation duct. Even if vibration is generated due to excessive wind speed or changes in wind pressure in the heating ventilation duct, the first clamping member and the second clamping member will not collide with the heating ventilation duct, thereby increasing the service life of the heating ventilation duct.

[0010] Regarding the connection between the clamping mechanism and the connecting rod, the end of the hinged shaft on one side is inserted on one side of the adjacent connecting rod, and the end of the hinged shaft on the other side is also inserted on one side of the adjacent connecting rod, and the end of the hinged shaft can be fine-adjusted at the height position of the connecting rod, which is used to adjust the height of the first clamping member and the second clamping member, and then to fine-tune the height of the heating and ventilation duct, which is convenient for adaptive adjustment of the height position of the heating and ventilation duct.

[0011] To facilitate the connection between the end of the articulated shaft and the bottom end of the connecting rod, a mounting groove is opened on the lower part of one side of the connecting rod close to the end of the articulated shaft, and the end of the articulated shaft is located in the mounting groove. A fine-tuning part is provided at the lower end of the connecting rod which can be pushed upward to the end of the articulated shaft. The fine-tuning part is an adjusting bolt, which extends vertically from the lower end of the connecting rod to the end of the articulated shaft in the mounting groove. The adjusting bolt is tightened and moved upward, driving the end of the articulated shaft to move upward, thereby achieving fine-tuning of the height of the HVAC duct.

[0012] To ensure that the two ends of the articulated shaft will not rotate with the corresponding connecting rods and reduce excessive shaking or swaying of the heating and ventilation duct due to vibration, the end of the articulated shaft is a rectangular structural end, which slides in the installation groove along the vertical direction and is adapted to the structure of the installation groove.

[0013] The clamping mechanism is also connected to the suspension rod through a guide connecting rod, which is used to ensure that the first clamping member and the second clamping member stably clamp the heating and ventilation duct. Specifically, the upper parts of the first clamping member and the second clamping member are provided with vertical holes in the vertical direction, and the guide connecting rod is slidably connected in the vertical holes. The upper end of the guide connecting rod is threadedly connected to the suspension rod.

[0014] After the first clamp and the second clamp clamp the heating and ventilation duct, the guide connecting rod needs to be moved vertically upward to be threadedly connected to the suspension rod. The length of the guide connecting rod is greater than the vertical distance from the upper end surface of the clamping mechanism to the lower end surface of the suspension rod. The length of the vertical hole is greater than the length of the guide connecting rod by 1-5 cm, which is used to store the guide connecting rod when the first clamp and the second clamp are rotated, and the length of 1-5 cm makes it easy to pull out the guide connecting rod and connect it to the suspension rod.

[0015] There are a large number of heating and ventilation ducts, and their installation heights are also different. In order to achieve the adjustable up and down positions of the heating and ventilation ducts after clamping and facilitate the installation of the heating and ventilation ducts, the length of the connecting rod is adjustable.

[0016] Regarding the specific structure of the connecting rod, the connecting rod includes an insertion rod and a sleeve. The insertion rod is connected to the end of the hinge shaft, the upper end of the sleeve is connected to the suspension rod, the insertion rod and the sleeve are connected by the insertion rod, and a plurality of sockets are provided on the sleeve.

[0017] The lower ends of the first clamping member and the second clamping member are connected in a manner that the connecting member is threadedly connected to the lower ends of the first clamping member and the second clamping member respectively, and the axis thereof is perpendicular to the axis of the hinge shaft.

[0018] When installing the HVAC duct, it is necessary to rotate the first clamp and the second clamp outward. During the rotation, in order to prevent the upper ends of the first clamp and the second clamp from colliding with the lower surface of the hanger and affecting the installation of the HVAC duct, the highest position that the upper end surfaces of the first clamp and the second clamp can reach is set to be lower than the height of the lower surface of the hanger.

[0019] The beneficial effect of the utility model lies in that the upper ends of the first clamping member and the second clamping member are hinged by a hinge shaft, and the two ends of the hinge shaft are connected to the suspension rod by connecting rods. The HVAC duct can be installed on the clamping surface by rotating the first clamping member and the second clamping member outward. The clamping surface is an arc-shaped surface, and the arc directions of the two arc-shaped surfaces are opposite. The lower ends of the first clamping member and the second clamping member are connected by a connecting member, so that the clamping surface and the outer wall of the HVAC duct are tightly connected, thereby reducing the collision between the HVAC branch pipe and the clamping mechanism due to vibration, thereby affecting its service life.

DETAILED DESCRIPTION

[0030] See also Figure 1 and Figure 2 The shown hanging bracket for a heating and ventilation duct is installed under a hanger 1 connected to a wall, and includes a clamping mechanism, which is connected to the hanger 1 through a connecting rod and a guide connecting rod 7. The hanger 1 is installed on a ceiling or the inner wall of a wall top, and is used to support the installation of the entire hanging bracket.

[0031] Among them, see Figure 7 As shown, the clamping mechanism includes a first clamping member 2 and a second clamping member 3, the upper ends of the first clamping member 2 and the second clamping member 3 are hinged by a hinge shaft 5, and the lower ends are connected by a connecting member 6. The opposite surfaces of the first clamping member 2 and the second clamping member 3 are provided with a clamping surface 4, which is adapted to the outer cylindrical surface of the heating ventilation duct. The heating ventilation duct is clamped by the first clamping member 2 and the second clamping member 3, and connected to the suspension rod 1 by a connecting rod, and the heating ventilation duct is hoisted. The clamping surface 4 of the first clamping member 2 and the second clamping member 3 is in close contact with the outer wall of the heating ventilation duct and will not collide with the heating ventilation duct. The heating ventilation duct is placed into the clamping surface 4 of the first clamping member 2 and the second clamping member 3 from bottom to top. Compared with the prior art that the heating ventilation duct is installed from one side or the upper part, the difficulty of installing the heating ventilation duct can be reduced, and the rapid installation of the heating ventilation duct is convenient.

[0032] The lower ends of the first clamping member 2 and the second clamping member 3 are connected in such a way that the connecting member 6 is threadedly connected to the lower ends of the first clamping member 2 and the second clamping member 3 respectively, and its axis is perpendicular to the axis of the hinge shaft 5. After the first clamping member 2 and the second clamping member 3 clamp the heating and ventilation duct, they are connected by a connecting rod to fasten the clamping surface 4 to the outer wall of the heating and ventilation duct.

[0033] There are many HVAC ducts, and their installation heights are different. Figure 5 As shown, the first clamping part 2 and the second clamping part 3 are extended from both ends of the articulated shaft 5, and are connected to the suspension rod 1 through a connecting rod, and the end of the articulated shaft 5 is installed in the connecting rod, and in order to achieve the adjustable up and down position of the heating and ventilation duct after clamping, the length of the connecting rod is adjustable.

[0034] See also Figure 2 and Figure 5 As shown, regarding the specific structure of the connecting rod, the connecting rod includes a vertically arranged plug rod 10 and a sleeve 11, a plurality of threaded holes 102 are provided on the upper part of the plug rod 10, the lower end of the plug rod 10 is connected to the end of the hinge shaft 5, the mounting groove 101 is provided on the plug rod 10, the upper end of the sleeve 11 is connected to the suspension rod 1, the plug rod 10 and the sleeve 11 are connected by a connector 12, and the sleeve 11 is provided with a plurality of sockets 111 at equal intervals along the length direction, the connector 12 passes through the sockets 111 of the sleeve 11 and is threadedly connected to the upper part of the plug rod 10, and by adjusting the position of the connector 12 in the sleeve 11, the overall length of the plug rod 10 and the sleeve 11 can be adjusted, thereby adjusting the distance between the heating and ventilation duct and the suspension rod 1.

[0035] See also Figure 6 As shown, a mounting groove 101 is provided at the lower part of one side of the connecting rod near the end of the hinge shaft 5, and the end of the hinge shaft 5 is installed in the mounting groove 101. Excessive wind speed or wind pressure changes in the heating ventilation duct may cause it to vibrate. In order to ensure that the two ends of the hinge shaft 5 will not rotate with the corresponding connecting rod, reduce the swing of the heating ventilation duct, and achieve stable installation of the heating ventilation duct, the end of the hinge shaft 5 is a rectangular structure end 51, which slides in the mounting groove 101 along the vertical direction, and the rectangular structure end 51 is adapted to the structure of the mounting groove 101. The connection rod adjusts the height position of the heating ventilation duct roughly. In order to cooperate with the connection rod to adjust the height position of the heating ventilation duct more accurately and achieve stable installation of the heating ventilation duct according to the preset position, the lower end of the connecting rod is provided with a fine adjustment member 8 that can be pushed upward to the end of the hinge shaft 5. The fine adjustment member 8 is an adjustment bolt, which extends vertically from the lower end of the connecting rod to the end of the hinge shaft in the installation groove. Tighten the adjustment bolt, the adjustment bolt moves upward, and drives the end of the hinge shaft to move upward, so as to achieve fine adjustment of the height of the heating ventilation duct.

[0036] See also Figure 7 As shown, Figure 7 This is the state when the first clamp 2 and the second clamp 3 are rotated outward. When installing the heating and ventilation duct, the first clamp 2 and the second clamp 3 need to be rotated outward. When rotating, in order to prevent the upper ends of the first clamp 2 and the second clamp 3 from colliding with the lower surface of the suspension rod 1 and affecting the installation of the heating and ventilation duct, the highest position that the upper end surfaces of the first clamp 2 and the second clamp 3 can reach is set to be lower than the height of the lower surface of the suspension rod 1.

[0037] Excessive wind speed or changes in wind pressure in the heating and ventilation duct may cause it to vibrate. For this reason, see Figure 3 and Figure 4As shown, the above-mentioned clamping mechanism is also connected to the suspension rod 1 through a guide connecting rod 7, which is used to ensure that the first clamping member 2 and the second clamping member 3 stably clamp the heating and ventilation duct. Specifically, the upper parts of the first clamping member 2 and the second clamping member 3 are provided with vertical holes 9 in the vertical direction, and the guide connecting rod 7 is slidably connected in the vertical hole 9. The upper end of the guide connecting rod 7 is threadedly connected to the suspension rod 1. The vertical hole 9 includes a long hole 91 and a short hole 92 that are connected and coaxially arranged, and the inner diameter of the long hole 91 is larger than the inner diameter of the short hole 92. The short hole 92 is located above the long hole 91, and the lower end of the guide connecting rod 7 is adapted to the long hole 91. When installing the HVAC duct, it is necessary to rotate the first clamp 2 and the second clamp 3 outward. During rotation, if the guide connecting rod 7 on the first clamp 2 and the guide connecting rod 7 on the second clamp 3 protrude longer than the vertical hole 9, they may collide with the lower surface of the suspension rod 1. Therefore, the length of the vertical hole 9 is set to be greater than the length of the guide connecting rod 7, and the vertical hole 9 is longer than the connecting rod 1-5 cm, which is used to store the guide connecting rod 7 when disassembling or replacing the HVAC duct, and is also convenient for taking out when connected to the suspension rod 1. During storage, the part of the connecting rod that leaks out of the vertical hole 9 is provided with an external thread for threaded connection with the suspension rod 1; at the same time, the excessive length of the guide connecting rod 7 is prevented from affecting the rotation of the first clamp 2 and the second clamp 3, thereby avoiding the phenomenon that the HVAC duct cannot be placed between the first clamp 2 and the second clamp 3 from bottom to top for clamping.

[0038] After the first clamping member 2 and the second clamping member 3 clamp the heating and ventilation duct, the guide connecting rod 7 needs to be pulled out vertically upward and moved up to be threadedly connected to the suspension rod 1. The length of the guide connecting rod 7 is set to be greater than the vertical distance from the upper end surface of the clamping mechanism to the lower end surface of the suspension rod 1, so as to facilitate the guide connecting rod 7 to move up and be threadedly connected to the suspension rod 1.
