Description

Technical Field

[0001] The utility model belongs to the technical field of central air-conditioning duct installation, and specifically relates to a central air-conditioning duct installation hanger. Background Art

[0002] When installing the central air conditioning duct, you need to use a hanger to hang the outlet duct on the ceiling or beam. When installing the central air conditioning duct hanger in the related art, you need to position the hanger setting and elevation according to the direction of the duct according to the construction drawings. Whether the hanger is installed strictly according to the drawings will directly affect the operation and service life of the air conditioning system.

[0003] A Chinese patent document with authorization announcement number CN218992594U discloses a central air conditioning duct mounting hanger, which controls the flow of oil in the hanger by opening and closing a manual valve, thereby smoothly adjusting the height of the mounting bracket while ensuring that the mounting plate is level.

[0004] However, in the prior art, when there is a slight deviation in the position where the hanger is fixed on the ceiling or beam, or when the position of the air duct needs to be fine-tuned after the hanger is installed, if the air duct is not located in the middle of the hanger as expected, it is difficult to fully ensure the fixing effect of the hanger on the air duct. For this reason, a central air-conditioning duct installation hanger is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a central air-conditioning air duct installation hanger.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A central air-conditioning duct mounting hanger, comprising a suspension assembly that can stably mount the hanger at a certain height below a ceiling or a beam, a clamping assembly that can ensure the hanger's fixing effect on the duct when the duct position deviates slightly from the expected position, and a supporting assembly that can cooperate with the clamping assembly to fully fix the duct is arranged below the clamping assembly;

[0008] The clamping assembly includes a bracket fixedly installed between the suspension assemblies, a clamping member that can be raised, lowered and moved laterally, an adjusting member that can conveniently adjust the position of the clamping member, and a transmission member that can connect the clamping member and the adjusting member.

[0009] Preferably, the clamping member comprises a sliding block movably connected in the bracket, and a clamping rod is movably connected to the sliding block.

[0010] Preferably, the transmission member comprises a connecting rod movably connected to the upper end of the clamping rod, a movable frame is arranged between the connecting rods, and a joint is movably installed in the movable frame.

[0011] Preferably, the adjusting member comprises a support fixedly mounted above the bracket, a screw rod is arranged between the joint and the support, and a rotary handle is fixedly connected to the upper end of the screw rod.

[0012] Preferably, the bracket and the clamping rod are both slidably connected to the slider.

[0013] Preferably, the clamping rod and the movable frame are both rotatably connected to the connecting rod, and the movable frame is rotatably connected to the joint.

[0014] Preferably, the joint is connected to the screw rod via threads, and the support is rotationally connected to the screw rod.

[0015] The beneficial effect of the utility model is that when the staff changes the position of the clamping parts and the supporting components through the adjusting parts, so that the hanger can fully fix the air duct with a slightly deviated position, the power from the adjusting parts can be transmitted to the two groups of clamping parts synchronously or asynchronously through the transmission parts until the two groups of clamping parts and the supporting components are in contact with the air duct, thereby fully ensuring the fixing effect of the hanger on the air duct.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0025] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings.

[0026] like Figure 1-Figure 4 As shown, a central air-conditioning duct installation hanger includes a suspension component 1 that can stably install the hanger at a certain height below the ceiling or beam, a clamping component 2 is arranged between the suspension components 1, and can ensure the fixing effect of the hanger on the air duct when the position of the air duct deviates slightly from the expected position, and a supporting component 3 is arranged below the clamping component 2 and can cooperate with the clamping component 2 to fully fix the air duct.

[0027] In this embodiment:

[0028] The suspension assembly 1 includes a positioning frame 101, a suspension rod 102 is movably connected above the positioning frame 101, and diagonal rods 103 are movably connected to the front and rear of the positioning frame 101; the suspension rod 102 and the diagonal rod 103 are both rotatably connected to the positioning frame 101; the connected positioning frame 101 is stably installed at a certain height above or below the ceiling or beam through the suspension rod 102 and the diagonal rod 103, and the clamping assembly 2 is installed through the positioning frame 101.

[0029] In this embodiment:

[0030] The clamping assembly 2 includes a bracket 201 fixedly installed between the suspension assemblies 1, a clamping member that can be lifted and moved laterally, an adjusting member that can conveniently adjust the position of the clamping member, and a transmission member that can connect the clamping member and the adjusting member. The clamping member includes a slider 202 movably connected to the bracket 201, and a clamping rod 203 is movably connected to the slider 202. The transmission member includes a connecting rod 204 movably connected to the upper end of the clamping rod 203, and a moving frame 205 is arranged between the connecting rods 204. A joint 206 is movably installed in the moving frame 205. The adjusting member includes a support 207 fixedly installed above the bracket 201, and a screw 208 is arranged between the joint 206 and the support 207. A rotary handle 209 is fixedly connected to the upper end of the screw 208;

[0031] The bracket 201 and the clamping rod 203 are both slidably connected to the slider 202, the clamping rod 203 and the moving frame 205 are both rotatably connected to the connecting rod 204, the moving frame 205 is rotatably connected to the joint 206, the joint 206 is threadedly connected to the screw 208, and the support 207 is rotatably connected to the screw 208;

[0032] By means of a slider 202 that can slide relative to the bracket 201, the distance between the two clamping rods 203 can be adjusted. By means of the clamping rod 203 that can slide relative to the slider 202, the supporting assembly 3 is driven to rise and fall in the hanger. When the screw rod 208 connected to the top of the support 207 is rotated by the handle 209, since the rotation of the joint 206 is restricted by other components, the joint 206 will be raised and lowered in the hanger after the screw rod 208 is rotated. When the height of the joint 206 changes, the movable frame 205 rotatably connected to the joint 206 can transmit the height change of the joint 206 to the two clamping rods 203 at the same time through the connecting rod 204.

[0033] In this embodiment:

[0034] The supporting assembly 3 includes a bracket 301 arranged below the support 201, a slide groove 302 is integrally formed in the bracket 301, and slide rods 303 are movably connected on both sides of the bracket 301; the clamping rod 203 and the slide rod 303 are connected by threads, and the bracket 301 is slidably connected to the slide rod 303; the bracket 301 is fixed between the two clamping rods 203 by the slide rod 303 that can slide and retract relative to the bracket 301, and the bracket 301 is in contact with the lower side of the air duct to stably support the air duct, and the slide groove 302 is used to limit the movable range of the slide rod 303 relative to the bracket 301.

[0035] Working principle:

[0036] When the installation of the air duct for the central air conditioner is completed by installing the hanger 102 and the inclined rod 103 according to the construction drawings, the hanger 102 and the inclined rod 103 are stably fixed on the ceiling or the beam through the expansion bolts and other connectors to complete the installation of the hanger; when the position of the air duct between the bracket 201, the clamping rod 203 and the bracket 301 deviates from the expected position, resulting in the air duct no longer being centered in the hanger, the height of the joint 206 can be adjusted by rotating the screw rod 208 through the rotary handle 209, so that the movable frame 205 pushes and pulls the clamping rod 203 to move horizontally or up and down through the connecting rod 204 until the bracket 301 is tightly against the air duct and a certain The clamping rod 203 is pressed against the air duct, and then the height of the joint 206 can be further adjusted. Since the position of one of the clamping rods 203 pressed against the air duct cannot be changed, and the other clamping rod 203 cannot be raised or lowered due to the bracket 301, the movable frame 205 will rotate relative to the joint 206 while the height of the joint 206 continues to change, so that the clamping rod 203 whose movement is not hindered continues to move until it contacts the air duct, thereby ensuring the contact effect between the bracket 201, the clamping rod 203, and the bracket 301 and the air duct after fine-tuning the position, and ensuring that the hanger can still fully fix the air duct.

[0037] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
