Description

Technical Field

[0001] The utility model relates to the technical field of tooling, and particularly relates to a novel fixing device for rubber samples at the valve nozzle of an inner tube. Background Technique

[0002] When conducting quality inspection on an inner tube, it is necessary to test the bonding strength of the rubber at the valve nozzle of the inner tube to determine whether the project is qualified and whether the quality meets the standard.

[0003] When testing the bonding strength of the rubber at the valve nozzle, it is necessary to manually replace the tooling and samples. When replacing the tooling, since the original tooling is large and heavy, it is also necessary to lift the original tooling to chest height before installing it on the equipment, which is very inconvenient and has potential safety hazards. When replacing the sample each time, it is necessary to confirm the position of the sample positioning hole on the original tooling many times before the sample can be successfully placed and the position of the sample needs to be adjusted many times to meet the perpendicularity requirement during the test, consuming a lot of time.

[0030] As Figure 1-3 shown, a fixing device for a rubber sample 5 at the valve of a new inner tube includes a connection structure 1, a placement structure and a clamping structure 3;

[0031] The connection structure 1 is used to connect with the original equipment 4; this part is responsible for connecting the sample 5 fixture with the original testing equipment to ensure that the entire device is firmly installed. The connection structure 1 includes a connection column 11 and a positioning pin 12, and the connection column 11 is provided with a fixing hole; during installation, the connection column 11 is inserted into the connection hole of the original equipment 4, and the positioning pin 12 passes through the side hole and the fixing hole of the connection hole to connect the fixture.

[0032] Among them, the connecting column 11 is inserted into the specific connecting hole of the original equipment 4, and the positioning pin 12 passes through the side hole of the original equipment 4 and the fixing hole of the connecting column 11, locking the position of the device, increasing the stability of the connection, and facilitating quick and safe installation and disassembly.

[0033] The placement structure is arranged at the lower part of the connecting structure 1 and is used to place the test sample 5; the placement structure includes a V-shaped frame 21 and a steel rod, and the two sides of the V-shaped frame 21 are provided with grooves 211 inclined downward, and the steel rod is placed in the grooves 211.

[0034] The placement structure is used to carry and position the test sample 5. The shaped frame 21 is designed with a groove 211 that is inclined downward, which facilitates the steel rod to slide in along the inclined surface, simplifying the placement process. The inclined groove design improves the convenience of operation. The annular cut on the steel rod cooperates with the groove 211 to limit the lateral movement of the steel rod, ensuring the stable positioning of the sample 5 during the test.

[0035] The clamping structure 3 is arranged on at least one side of the placement structure and is used to fix the placement structure.

[0036] The clamping structure 3 includes a pressure rod 31 and a spring 32; one end of the pressure rod 31 is provided with a notch 312, and the other end is provided on the placement structure through a rotating shaft; one end of the spring 32 is connected to the middle of the pressure rod 31, and the other end is connected to the placement structure. The spring 32 is a tension spring, and the other end of the tension spring is provided on the placement structure facing the notch 312. In another embodiment, the spring 32 is a compression spring, and the other end of the compression spring is provided on the placement structure facing away from the notch 312.

[0037] The clamping structure 3 is composed of a pressure rod 31 and a spring 32, which is responsible for fixing the steel rod with the sample 5 on the placement structure to ensure that the sample 5 is stable and does not shift during the test. The pressure rod 31 is installed through a rotating shaft, and the notch 312 at one end is designed to be lifted after being pressed, which is convenient for putting in or taking out the steel rod. The spring 32 (whether it is a tension spring or a compression spring) applies force to the pressure rod 31 so that the notch 312 of the pressure rod 31 fits tightly against the steel rod, thereby achieving reliable fixation of the steel rod. The choice of spring 32 (tension spring or compression spring) depends on the specific application scenario and design requirements. This embodiment provides a structural drawing using a tension spring, which can effectively improve the clamping effect and reduce the risk of the sample 5 jumping out due to external force during the test. At the same time, the verticality requirements are guaranteed, thereby improving the accuracy and safety of the test.

[0038] The steel rod is provided with an annular cutout for cooperating with the groove 211 to prevent the steel rod from moving left and right, and can position the sample 5 in left and right directions to prevent the sample 5 from sticking to the yoke 21, thereby improving the test efficiency.

[0039] A pressing portion 311 is provided from one end surface of the pressing rod 31 to the rotation axis, which is used to press the pressing rod 31 and lift the notch 312. When the operator applies pressure to the pressing portion 311, the notch 312 of the pressing rod 31 will lift accordingly, thereby controlling the clamping state of the clamping structure 3 on the steel rod. The existence of the pressing portion 311 makes it easier for the operator to apply force to the pressing rod 31, and the clamping mechanism can be activated or released by a simple pressing action, without the need for complex hand movements or tool assistance, thereby improving the convenience of operation.

[0040] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
