Abstract
Description
Technical Field
[0001] This invention relates to the field of automotive positioning technology, and in particular to a limiting hose clamp for automotive cooling pipes. Background Technology
[0002] Limiting hose clamps are special pipe connection locking accessories for automotive cooling systems. They are mainly used for connecting and fixing engine cooling hoses to rigid pipe joints. They are commonly used for assembling and locking cooling pipes throughout the vehicle, including water tanks, water pumps, and thermostats. By tightening and wrapping the pipe connection with the ring-shaped clamp, they provide a fastening, binding, and sealing function, preventing pipe loosening, displacement, and leakage at the joints, and ensuring stable cooling pipe connections.
[0003] Currently used limit hose clamps mainly use worm gear transmission for control, which is not stable enough and is prone to deformation. The worm gear is generally a fixed planar structure, which cannot accurately fit the pipe, and may even cause the pipe to deform when locked, affecting the stability of the pipe and lacking the function of stable pipe positioning. Summary of the Invention

The connecting hinge is fixed to the operating lug of the elastic ring hoop and is fixed by screws; the support includes two sets of plug-in slides, which can be slidably inserted into the connecting slot; two sets of long connecting rods are hinged to the outside of each plug-in slide, and the other end of the four sets of long connecting rods on both sides is hinged to a main hinge; short connecting rods are hinged to the middle of each long connecting rod, and the other end of the four sets of short connecting rods is hinged to a secondary hinge; the long connecting rods and short connecting rods constitute a scissor mechanism.
[0006] Optionally, the U-shaped carriage and the support hinge are fixedly connected by two sets of connecting screws.
[0007] Optionally, the supporting hinge seat and the connecting hinge seat are hinged together by a hinge screw, the bottom of the hinge screw is a screw structure, and the position where the hinge screw contacts the connecting hinge seat is a smooth rod.
[0008] Optionally, a connecting plate is fixedly provided below the control slide, and a positioning plate is provided below the connecting plate; the adjacent positions of the connecting plate and the positioning plate are all tooth-like structures, the tooth-like structures of the connecting plate and the positioning plate are matched and connected, and fixedly connected by connecting bolts; the positioning plate has two pairs of strip holes for assembly.
[0009] Optionally, a threaded cylinder is integrally provided in the middle of one side of the secondary hinge seat.
[0010] Optionally, a control screw is rotatably provided in the middle of the main hinge seat. The front side of the control screw is a smooth rod structure, and the front end of the control screw is a quadrilateral platform. The rear end of the control screw is a screw structure and is threadedly connected to the threaded cylinder.
[0011] Optionally, the front end of the control screw passes through the main hinge seat and is fixedly fitted with a butterfly button cover by a bolt.

[0013] The beneficial effects are as follows:
[0014] The scissor mechanism, consisting of a long connecting rod and a short connecting rod, combined with a threaded transmission structure, can precisely drive two sets of U-shaped carriages to move synchronously in opposite directions or in opposite directions. This, in turn, drives the elastic hoop to achieve smooth and high-precision expansion and contraction adjustment, making it suitable for cooling pipes of different circumferences. At the same time, the bidirectional limiting structure of the elastic hoop can precisely limit the adjustment stroke of the hoop, ensuring the stability of the pipe clamping and locking, while avoiding excessive deformation of the hoop and damage to the pipe under pressure, thus improving the adjustment control accuracy and reliability of the hose clamp.
[0015] By using a separate assembly structure of the elastic ring clamp, control slide, and pluggable support, the locking and adjustment functions of the hose clamp are separated. This allows for easy replacement of faulty parts, significantly reducing production and usage costs. The independent replacement and maintenance of the elastic ring clamp is supported by the original support, improving the product's assembly adaptability and economic efficiency.
[0016] The connecting plate and the positioning plate have a toothed meshing connection structure, which allows for flexible adjustment of the installation angle and fixed position of the hose clamp body. This adapts to the installation requirements of cooling pipes with different directions and installation points within the vehicle frame. In conjunction with the strip-shaped mounting holes on the positioning plate, it is compatible with different hole spacings on the vehicle frame, enabling flexible installation of the hose clamp in multiple positions and at multiple angles. This significantly improves the product's adaptability to various scenarios and ease of installation. Attached Figure Description

The insertable slide bars 701 can be slidably inserted into the connecting slot 301. Two sets of long connecting rods 702 are hinged to the outside of each insertable slide bar 701. The other end of the four sets of long connecting rods 702 on both sides is hinged to a main hinge seat 704. Short connecting rods 703 are hinged to the middle of each long connecting rod 702. The other end of the four sets of short connecting rods 703 is hinged to a secondary hinge seat 705. The long connecting rods 702 and the short connecting rods 703 constitute a scissor mechanism.
[0023] The U-shaped carriage 3 and the support hinge 302 are fixedly connected by two sets of connecting screws 303.
[0024] The supporting hinge 302 and the connecting hinge 304 are hinged together by a hinge screw 305. The bottom of the hinge screw 305 is a screw structure, and the contact position between the hinge screw 305 and the connecting hinge 304 is a smooth rod.
[0025] Among them, a connecting plate 4 is fixedly installed below the control slide 2, and a positioning plate 5 is installed below the connecting plate 4; the adjacent positions of the connecting plate 4 and the positioning plate 5 are both tooth-like structures, the tooth-like structures of the connecting plate 4 and the positioning plate 5 are matched and connected, and are fixedly connected by connecting bolts 6; the positioning plate 5 has two pairs of strip holes for assembly.
[0026] Among them, a threaded cylinder 706 is integrally provided in the middle of one side of the secondary hinge seat 705.
[0027] The main hinge seat 704 has a control screw 707 rotatably mounted in the middle.

The two ends of the butterfly button cover 708 are fin structures, and rubber anti-slip pads are fixedly installed on both sides of the fin structure.
[0029] Among them, the two ends of the opening of the elastic ring hoop 1 are respectively provided with mutually cooperating limiting structures to limit the minimum shrinkage of the elastic ring hoop 1; the two sets of operating lugs abut against each other when the elastic ring hoop 1 is opened to the preset maximum stroke to limit the maximum opening of the elastic ring hoop 1.
[0030] Main body positioning: Pass the cooling pipe through the elastic ring 1, and then fix the positioning plate 5 on the outside of the frame to complete the positioning and installation of the hose clamp main body.
[0031] Adjustment mechanism assembly: Insert the plug-in slide bar 701 into the connection slot 301 to complete the connection and prepare for subsequent adjustment.
[0032] Pipe diameter adaptation adjustment: Adjust the expansion range of the elastic ring 1 according to the circumference of the cooling pipe to make the elastic ring 1 fit the cooling pipe. The specific adjustment process is as follows: Rotate the butterfly knob cover 708 to drive the control screw 707 to rotate. The control screw 707 and the threaded cylinder 706 form a threaded transmission, driving the threaded cylinder 706 and the secondary hinge seat 705 to move, changing the distance between the main hinge seat 704 and the secondary hinge seat 705; through the linkage control of the short connecting rod 703 and the long connecting rod 702, adjust the position of the two sets of plug-in slides 701, and then through the cooperation of the plug-in slides 701 and the connecting slot 301, simultaneously adjust the position of the U-shaped slide 3; by adjusting the position of the two sets of U-shaped slides 3, change the position of the connecting hinge seat 304, and use the connecting hinge seat 304 to drive the elastic ring 1 to expand or contract, so as to achieve size adaptation of different pipe diameters.
[0033] Large-size pipe adaptation: For larger cooling pipes, the elastic ring 1 can be expanded in advance, the cooling pipe can be inserted, and then the elastic ring 1 can be contracted to complete the clamping and fixing.
[0034] Example 2: Based on Example 1, if the elastic ring hoop 1 deforms after long-term use and needs to be replaced, the matching support 7 does not need to be replaced and can be reused in combination with the new elastic ring hoop 1.
[0035] Example 3: Based on Example 1, the U-shaped slide 3 is fixed, but the control slide 2 can slide outside the U-shaped slide 3. If anti-slip is required, a rubber anti-slip layer can be set between the contact surfaces of the U-shaped slide 3 and the control slide 2, or hot melt adhesive can be used for fixing.
[0036] The specific usage and function of this embodiment: In this invention, when used, as follows: Figure 8 This method allows for the fixed installation of cooling pipes in different directions; The goal is to pass the cooling pipe through the elastic ring 1 and then fix the positioning plate 5 to the outside of the frame to complete the positioning; Insert the plug-in slider 701 into the connection slot 301 to complete the connection, and then make further adjustments; The expansion range of the elastic ring 1 is adjusted according to the circumference of the cooling pipe so that the elastic ring 1 fits the cooling pipe. The butterfly knob cover 708 is directly rotated to drive the control screw 707 to rotate. The rotation of the control screw 707 and the threaded cylinder 706 form a thread transmission effect, controlling the movement of the threaded cylinder 706 and the secondary hinge seat 705. Then, the distance between the main hinge seat 704 and the secondary hinge seat 705 changes. The short connecting rod 703 and the long connecting rod 702 provide adjustment control to adjust the position of the two sets of plug-in slide bars 701. Then, the plug-in slide bars 701 cooperate with the connecting slot 301 to directly adjust the position of the U-shaped slide 3. By adjusting the positions of the two sets of U-shaped carriages 3, the position of the connecting hinge 304 can be adjusted. The connecting hinge 304 can be used to expand or contract the elastic ring 1 to achieve size adaptation. If the cooling pipe is large, the elastic ring 1 can be expanded in advance and then the cooling pipe can be inserted. Support 7 is recyclable.
