Background
Hose stretch testing is an important quality control process for testing the durability and resiliency of a hose when subjected to tensile forces. Such testing may help manufacturers ensure that their products can withstand various pressures in actual use through hose stretch testing.
The hose stretch detection steps are as follows: a number of hose samples are first randomly selected from the production line. The original length of each hose sample was measured and recorded. A predetermined tensile force was applied to each hose sample using a dedicated tensile tester. The amount of stretching force is generally determined according to the type of hose and the intended use conditions. After the tensile force was applied, the length of each hose sample was measured and recorded. The tensile force applied to the hose sample was released and the length of the hose after recovery to the unstretched state was measured and recorded. All measurements were analyzed to determine the tensile properties of each hose sample. Wherein clamps are required to secure both ends of the hose to the tester. However, during the tensile test, the two ends of the hose deform and slip off easily from the clamping type clamp. In order to ensure the accuracy of the hose test, fixing holes cannot be formed in the end portions of the hose to fix the two ends of the hose.
Therefore, the above-mentioned existing technical drawbacks need to be changed.

In one aspect, the present utility model provides a hose stretching clamp and stretching apparatus for testing the durability and elasticity of a hose when subjected to a stretching force, as shown in fig. 1, 2 and 3. The hose stretch test helps the manufacturer ensure that the product will withstand various pressures in actual use. The main structure comprises: the first clamp assembly 1 and the second clamp assembly 2 are respectively used for clamping and fixing the end parts of two ends of the hose. The first clamp assembly 1 comprises a first base 11, a first movable rod 12 and a first fixed rod 13, wherein the first fixed rod 13 is fixedly arranged on the first base 11, the first movable rod 12 is movably connected to the first base 11, the first movable rod 12 slides towards the first fixed rod 13 so that the first movable rod 12 and the first fixed rod 13 form a clamping structure, the second clamp assembly 2 comprises a second clamp base 21, a second movable rod 22 and a second fixed rod 23, the second fixed rod 23 is fixedly arranged on the second clamp base 21, the second movable rod 22 is movably connected to the second clamp base 21, and the second movable rod 22 slides towards the second fixed rod 23 so that the second movable rod 22 and the second fixed rod 23 form a clamping structure; in use, the ends of the hose are wrapped at least one turn around the first movable bar 12 and the second movable bar 22, respectively, and the movable bars (the first movable bar 12 and the second movable bar 22) and the fixed bars (the first fixed bar 13 and the second fixed bar 23) can primarily clamp the ends of the hose. The stretching device is started to stretch and detect the hose.

In the tensile test, both ends of the hose deform and slip from the clamp. In order to ensure the accuracy of the hose test, fixing holes cannot be formed in the end portions of the hose to fix the two ends of the hose. The present solution first winds the ends of the hose around the first movable bar 12 and the second movable bar 22, respectively, before performing the hose tensile test. When the hose is stretched, the first movable rod 12 and the second movable rod 22 are pulled to approach the first fixed rod 13 and the second fixed rod 23 respectively, so that gaps between the first movable rod 12 and the first fixed rod 13 and between the first movable rod 12 and the first fixed rod 13 become smaller, and the clamping force between the movable rod and the fixed rod becomes larger as the tensile force becomes larger. Therefore, the technical effect of pulling more tightly can be realized, and the software is prevented from slipping from the clamp.
Further, as shown in fig. 1 and 3, the first base 11 is provided with at least two first connecting rods 111 along the direction of the second clamp base 21, a first separation groove 112 is formed between the two first connecting rods 111, and the ends of the first movable rod 12 and the first fixed rod 13 are respectively connected to the two first connecting rods 111, so that the first movable rod 12 and the first fixed rod 13 are located in the first separation groove 112. In this embodiment, two first connecting rods 111 are preferred, and the two first connecting rods 111 are respectively connected to two ends of the first fixed rod 13 and the first movable rod 12 to balance the tension of the hose. In the process of hose stretching test, the stress of the first movable rod 12 and the first fixed rod 13 is more uniform.
Further, as shown in fig. 1 and 3, the second clamp base 21 is provided with at least two second connection bars 211 along the direction of the first base 11, a second separation groove 212 is formed between the two second connection bars 211, and ends of the second movable bar 22 and the second fixed bar 23 are respectively connected to the two second connection bars 211, so that the second movable bar 22 and the second fixed bar 23 are located in the second separation groove 212. As described above, in the present embodiment, two second connecting rods 211 are preferable, and the two second connecting rods 211 are connected to two ends of the second fixed rod 23 and the second movable rod 22, respectively, so as to balance the tension of the hose. In the process of hose stretching test, the stress of the second movable rod 22 and the second fixed rod 23 is more uniform.

It is understood that the first elastic member 113 may always maintain a clamped state between the first movable lever 12 and the first fixed lever 13. When the hose is wound on the first movable rod 12 and the first fixed rod 13, the elastic piece pulls the first movable rod 12 to approach the first fixed rod 13, so that the effect of primarily clamping and fixing the hose can be achieved.

Further, as shown in fig. 1, 2 and 3, at least one of the first movable rod 12 and the first fixed rod 13 has a cylindrical structure; at least one of the second movable rod 22 and the second fixed rod 23 has a cylindrical structure. The first movable rod 12 and the first fixed rod 13 are configured into a cylindrical structure, so that the hose is wound conveniently, and when the hose is stretched, the contact part of the hose and the movable rods (the first movable rod 12 and the second movable rod 22) and the fixed rods (the first fixed rod 13 and the second fixed rod 23) is stressed more uniformly.
A second aspect provides a stretching device comprising: stretching device body and hose stretching clamp according to any one of the first aspect, the stretching device body is provided with a stretching mechanism, and the first clamp assembly 1 and the second clamp assembly 2 are respectively installed at both ends of the stretching mechanism.
In summary, the present application provides a hose stretching clamp and a stretching device, in which two ends of a hose are first wrapped around a first movable rod 12 and a second movable rod 22, respectively, before a hose stretching test is performed. When the hose is stretched, the first movable rod 12 and the second movable rod 22 are pulled to approach the first fixed rod 13 and the second fixed rod 23 respectively, so that gaps between the first movable rod 12 and the first fixed rod 13 and between the first movable rod 12 and the first fixed rod 13 become smaller, and the clamping force between the movable rod and the fixed rod becomes larger as the tensile force becomes larger. Therefore, the technical effect of pulling more tightly can be realized, and the software is prevented from slipping from the clamp.
