Abstract

The invention discloses a plugging device which comprises a driving mechanism and a plugging mechanism connected with the driving mechanism. The plugging mechanism comprises a cylinder, a support, a guide sleeve and a pull rod, one side of the cylinder is connected with the driving mechanism, a cylinder connector extends out of the driving mechanism in a backing manner, the support is fixed on the cylinder, a guiding hole is formed in one surface of the support far away from the cylinder, one end of the guide sleeve is fixed at the outer edge of the guiding hole, the other end of the guide sleeve extends toward the direction far away from the guiding hole, the bottom end of the pull rod is connected with the cylinder connector, the top end of the pull rod sequentially penetrates the guiding hole and the support and then is connected with a pull block, and an annular projection is arranged on the front side of the pull rod and positioned between the pull block and the guide sleeve. Reliable plugging operations are achieved by the cylinder without manpower, and the plugging device is convenient to use.

Description

technical field [0001] The invention relates to the field of leak test and detection devices for automobile engine water channels, in particular to a blocking device. Background technique [0002] At present, when the engine waterway is tested for leaks, the water pipe mouth is usually blocked by the end face of the hole to be blocked. The patent application number: 201610028443.0 discloses a sealing device for the hole of the engine oil dipstick, such as figure 1 -2, wherein the sealing mechanism of the sealing device mainly includes a guide sleeve 2a, a pull rod 1a and a handle 3a, wherein the pull rod 1a is installed in the guide sleeve, and its front end is used to fix the sealing end of the sealing ring 4a, and its The rear end is rotatably connected with the cam part 31a of the handle 3a. When in use, the handle 3a is turned, the cam part 31a rotates, and the pull rod 1a moves away from the oil dipstick hole relative to the sleeve 2a. At this time, the sealing sleeve i...
