Description

Technical Field

[0001] This invention belongs to the field of connection structures and relates to a quick-release clamp fixing device with adjustable fixed distance. Background Technology

[0002] In the field of aircraft airborne environmental control systems, pipe connections within large refrigeration packages are typically made using quick-release clamps. However, under certain conditions, the connection point of two long pipes can experience greater vibrations during operation on the aircraft compared to connections with other shorter pipes, making the pipe connection more susceptible to damage.

[0003] Most existing fixing devices are custom-made fixed-length brackets based on the digital model, with one end clamped to the pipe and the other end fixed to a usable fixing point on the machine. The advantage of this type of fixing bracket is its simple structure and light weight. The disadvantage is that each fixing point needs to be designed independently, lacking versatility. In actual applications, there are deviations between the actual machine and the digital model, and stress exists during installation.

[0004] There is a problem with the existing technical solutions: there is no adjustable fixing device that can be installed on quick-release clamps. Summary of the Invention

[0005] The purpose of this invention is to provide a quick-release clamp fixing device with adjustable fixed distance. This invention features adjustable distance, simple assembly and disassembly, no need to modify the clamp, and no installation stress.

[0006] The technical solution of the present invention is as follows: a quick-release clamp fixing device with adjustable fixed distance, comprising: two pairs of mounting sections, two pairs of support arms, an adjusting component, and a fixing component; wherein, the two pairs of mounting sections are connected to the two pairs of support arms via joints; the adjusting component is connected to the two pairs of support arms via joints, and the other end of each pair of support arms is connected to the fixing component via joints; the mounting sections are mounted on the clamp rings, and the fixing component is connected to the required fixing point.

[0007] In the aforementioned fixed-distance adjustable quick-release clamp fixing device, the joint connection is a bolt connection.

[0008] In the aforementioned fixed-distance adjustable quick-release clamp fixing device, the mounting section can move along the clamp's retaining ring. The mounting section includes: the left mounting section and the right mounting section; the left mounting section and the right mounting section are connected by screws, the connecting hole of the left mounting section is a countersunk hole, and the connecting hole of the right mounting section is a threaded hole, and the two are connected by screws.

[0009] In the aforementioned fixed-distance adjustable quick-release clamp fixing device, the left mounting section and the right mounting section respectively have corresponding flanges and grooves located on the connecting surface, and the flanges and grooves are aligned on the connecting surface.

[0010] In the aforementioned fixed-distance adjustable quick-release clamp fixing device, the mounting arm is provided with three sets of holes. The three sets of holes from top to bottom are respectively used to connect with the fixing component, the adjusting component, and the mounting section. The fixing component and the mounting section are connected by bolts through the first and third sets of holes to form a movable joint. The adjusting component is rotatably installed in the second set of holes.

[0011] In the aforementioned fixed-distance adjustable quick-release clamp fixing device, the adjusting component can adjust its own length to adjust the opening angle of the support arm, thereby changing the distance between the fixing component and the clamp and locking it. The adjusting component includes: a through plate, a stop plate, a limiting screw L, and a limiting screw S. The through plate has a threaded hole and a through hole, and the stop plate has a threaded hole and a countersunk hole. The limiting screw L passes through the through hole of the through plate and screws into the threaded hole of the stop plate to limit the maximum opening angle of the support arm. The limiting screw S screws through the threaded hole of the through plate and abuts against the countersunk hole of the stop plate to limit the minimum opening angle of the support arm. The limiting screw L and the limiting screw S cooperate to lock the length of the adjusting component.

[0012] In the aforementioned fixed-distance adjustable quick-release clamp fixing device, the through plate and the stop plate are respectively installed on two pairs of support arms through their own rotating shafts, and can rotate around their own rotating shafts. When adjusting the length of the limit screw L, it can ensure that the through plate and the stop plate are always parallel to each other.

[0013] In the aforementioned fixed-distance adjustable quick-release clamp fixing device, multiple oblique through holes should be provided on the screw-through plate for the safety of driving limit screws.

[0014] In the aforementioned fixed-distance adjustable quick-release clamp fixing device, the fixing component includes: a joint and a replaceable fixing head; the joint and the replaceable fixing head are connected by a combination of tenons and screws, and the overall structure of the replaceable fixing head is an L-shaped plate, or it can be made into a straight plate or in the form of a pipe clamp.

[0015] Compared with existing technologies, this invention utilizes the principle of adjustable clamp distance. By changing the angle between the two support arms, the distance between the fixing component and the clamp is adjusted. Compared with traditional fixing structures, this structure has the advantages of adjustable distance, simple assembly and disassembly, no need to modify the clamp, no installation stress, and flexible fixing interface.

[0016] The mounting section of this invention, fixed to the clamp, consists of two parts secured with screws. The connecting surfaces of the two parts each have grooves to prevent slippage. The angle between the support arms is adjusted via an adjusting assembly. After adjustment, the length of the adjusting assembly can be locked by tightening the limiting screw. The fixing assembly consists of a joint and a replaceable fixing head. The replaceable fixing head comes in different forms and can be replaced according to actual needs. The key technical point of this invention is that by adjusting the length of the adjusting rod to change the angle between the support arms, the distance between the fixing point and the clamp can be adjusted.

[0017] This invention can be installed on the clamps and rings of the GJB 3821A series for fixation without requiring any modification to the clamps.

[0018] The distance between the fixing component and the clamp in this invention can be adjusted within a certain range using an adjusting rod;

[0019] The distance can be locked after the adjustment rod of this invention is adjusted.

[0020] The device of this invention has a simple structure, is easy to assemble, and has low manufacturing costs.

[0021] The fixing components of this invention are replaceable and can be replaced as needed depending on the actual installation situation. Attached Figure Description

[0030] Example 1. A quick-release clamp fixing device with adjustable fixed distance, see [link to example]. Figures 1-4 It includes: mounting section 1, support arm 2, adjustment component 3, and fixing component 4.

[0031] The two pairs of mounting sections 1 are connected to the two pairs of support arms 2 by joints. The adjustment component 3 is connected to the two pairs of support arms by joints. The two pairs of support arms 2 are connected to the fixing component 4 by joints. The mounting section 1 is installed on the clamp ring. The fixing component 4 is connected to the required fixing point.

[0032] Furthermore, the mounting section 1 is assembled from the left mounting section 1a and the right mounting section 1b, and can move along the clamp ring after assembly. The left mounting section 1a and the right mounting section 1b are connected by screws. The connecting hole of the left mounting section 1a is a countersunk hole, and the connecting hole of the right mounting section 1b is a threaded hole. The two are connected by screws.

[0033] Furthermore, the left mounting section 1a and the right mounting section 1b each have corresponding flanges and grooves on the connecting surface. The projections of the outer joint bosses of both on the connecting surface should not interfere with the connecting screws, ensuring convenient assembly and reliable connection.

[0034] Furthermore, the mounting arm 2 has three sets of holes, which are used to connect to the fixing component 4, the adjusting component 3, and the mounting section 1 from top to bottom, respectively. The fixing component 4 and the mounting section 1 are connected by bolts to form a movable joint, and the adjusting component 3 can be directly installed in the middle hole on the mounting arm.

[0035] Furthermore, the adjusting component 3 can adjust its own length to adjust the opening angle of the support arm 2, thereby changing the distance between the fixing component 4 and the clamp and locking it. The adjusting component 3 includes: a through plate 3a, a stop plate 3b, a limiting screw L3c, and a limiting screw S3d. The through plate 3a has a threaded hole and a through hole, and the stop plate 3b has a threaded hole and a countersunk hole. The limiting screw L3c passes through the through hole of the through plate 3a and screws into the threaded hole of the stop plate 3b to limit the maximum opening angle of the support arm. The limiting screw S3d screws through the threaded hole of the through plate 3a and abuts against the countersunk hole of the stop plate to limit the minimum opening angle of the support arm. The limiting screws L3c and S3d cooperate to lock the length of the adjusting component.

[0036] Furthermore, the through plate 3a and the stop plate 3b are respectively mounted on two pairs of support arms 2 via their own shafts and can rotate along the axis. When adjusting the length of the limit screw L3c, it can be ensured that the through plate 3a and the stop plate 3b are always parallel to each other. The through plate 3a should be provided with multiple oblique through holes for the safety of the limit screw. The limit screws L3c and S3d can be selected according to the actual situation and the appropriate length combination can be selected.

[0037] Furthermore, the fixing component 4 includes a joint 4a and a replaceable fixing head 4b, wherein the joint 4a and the replaceable fixing head 4b are connected by a combination of tenons and screws. The replaceable fixing head 4b can be in various forms. For example, the figure shows an L-shaped plate, but it can also be made into a straight plate or into a pipe clamp to connect and fix it to other pipes.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should be covered within the protection scope of the present invention.
