Description

Technical Field

[0001] The utility model relates to the technical field of automobile radiator matching fixtures, in particular to a radiator water leakage detection fixture. Background Art

[0002] An automotive radiator consists of three parts: the water inlet chamber, the water outlet chamber, and the radiator core. Coolant flows within the radiator core, while air passes through it. Hot coolant cools as it loses heat to the air, while cold air warms as it absorbs the heat dissipated by the coolant. Because the medium circulating within an automotive radiator is coolant, the radiator's sealing performance is a concern. Some radiators with special structures must pass a water leak detection jig to verify that no leaks are present in order to qualify. The primary task of a radiator water leak detection jig is to ensure a simple and quick seal on the radiator water pipe port while ensuring a leak-proof seal.

[0003] Currently, a radiator water leak detection jig is a specially designed tool that simulates the working environment of the radiator and uses water or other liquids as a medium to detect whether there are leaks inside the radiator and at its connection points. The jig's claws are usually fastened to the water outlet of the radiator's water chamber and tightened by a screw rod to ensure the seal between the jig and the radiator. The staff then injects the detection medium and injects a certain amount of water or other detection medium into the radiator through the jig's connecting pipe to simulate the radiator's working environment and perform the detection operation. For example, a radiator water leak detection jig disclosed in Chinese patent publication number CN209961414U has a claw at one end of the claw cover that is fastened to the water outlet of the water chamber, and the other end of the claw cover is screwed into the screw rod through a rod thread. One end of the screw rod is connected to a sealing gasket on the inner cross-section of the claw cover, which has the beneficial technical effects of good sealing, simple and practical structure, and good sealing effect.

[0004] However, in actual use, when the above device is used to seal the port of the radiator water chamber, the claw cover is installed, and then the sealing gasket is screwed into the port of the radiator water chamber by rotating the rotary rod to seal the port. The operation is cumbersome. When water inspection is required for batches of radiators, the manual labor is large and the inspection efficiency is low. Utility Model Content

[0005] The purpose of the utility model is to provide a radiator water leakage detection fixture, which has the effect of sealing the port of the radiator water chamber and is easy to operate, so that workers can perform radiator water inspection operations.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a radiator water leakage detection fixture, comprising a fixing seat, a fixing rod being installed through the upper end surface of the fixing seat, a fixing plate being installed on the upper end surface of the fixing rod, a first silicone tube, a first fixing ring, a second silicone tube and a connecting tube being movably sleeved on the outer side wall of the fixing rod from top to bottom, the upper and lower ends of the first silicone tube being fixedly connected to the fixing plate and the first fixing ring respectively, and the upper and lower ends of the second silicone tube being fixedly connected to the first fixing ring and the connecting tube respectively;

[0007] A movable cylinder movably sleeved on the outer wall of the fixed rod is fixedly installed on the bottom of the connecting cylinder, and a fixed cylinder slidably connected to the inner wall of the movable cylinder and fixedly sleeved on the outer wall of the fixed rod. Two micro electric push rods distributed on the left and right are provided inside the fixed cylinder, and two through holes distributed on the left and right are formed through the upper end surface of the fixed cylinder. The output ends of the two micro electric push rods pass through the two through holes respectively and are fixedly connected to the bottom of the connecting cylinder.

[0008] In order to fix the position of the fixing cylinder and prevent it from moving, as a preferred radiator water leakage detection fixture of the present invention, the bottom end surface of the fixing cylinder is fixedly connected to the upper end surface of the fixing seat.

[0009] In order to fix the positions of the two micro electric push rods, as a preferred embodiment of the radiator water leakage detection fixture of the present invention, the two micro electric push rods are both installed on the upper end surface of the fixing seat.

[0010] In order to facilitate the extrusion of the first silicone tube and the second silicone tube to deform them and seal the radiator water chamber port, as a preferred radiator water leakage detection fixture of the present invention, the first silicone tube and the second silicone tube are both elastic.

[0011] In order to facilitate the installation of the micro electric push rod, as a preferred radiator water leakage detection fixture of the present invention, the cross section of the fixing tube is "U"-shaped.

[0012] In order to increase the friction of the fixing seat and play an anti-slip role, as a preferred radiator water leakage detection fixture of the present invention, the outer side wall of the fixing seat is provided with anti-slip grooves.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] When the utility model is used, the device is placed at the port of the radiator water chamber, and the first silicone tube, the second silicone tube, the connecting tube and the moving tube are placed in the port of the radiator water chamber. By starting the two micro electric push rods, the connecting tube squeezes the first silicone tube and the second silicone tube to cause them to deform, so that the first silicone tube and the second silicone tube are tightly attached to the inner wall of the port of the radiator water chamber, thereby achieving the effect of sealing the port of the radiator water chamber. The operation is convenient, so that the staff can carry out radiator water inspection operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Working principle:

[0033] First, when using the device to test the sealing of the radiator, the staff first picks up the fixing seat 1 and places the first silicone tube 3, the second silicone tube 4, the connecting tube 5 and the movable tube 6 into the port of the radiator water chamber. At this time, the size of the fixing seat 1 is larger than the port of the radiator water chamber, and it is located on the port of the radiator water chamber. Then the staff starts the two micro electric push rods 8 to push the connecting tube 5 to drive the movable tube 6 to move along the fixed tube 7. At this time, the connecting tube 5 moves along the fixed rod 2 to squeeze the first silicone tube 3 and the second silicone tube 4 to cause them to deform, so that the first silicone tube 3 and the second silicone tube 4 are tightly attached to the inner wall of the port of the radiator water chamber, so as to facilitate the sealing of the ports of radiator water chambers of different sizes and facilitate the staff to perform radiator water inspection operations.
