Description

Technical Field

[0001] This invention relates to the field of equipment grease sampling, and more particularly to an oil dipstick and a matching oil sampling bottle. Background Technology

[0002] The equipment used in oil and grease testing laboratories is a crucial tool for equipment management and predictive maintenance. The sampling requirements for the oils being tested are quite stringent, as they must be completely free from contamination. Traditional sampling methods typically involve using a syringe with a section of plastic tubing to extract the sample, which is then filled into a sample bottle for preservation. Because oil samples cannot be cross-contaminated, one set of sampling tools can only be used to sample one piece of equipment. Furthermore, oil-contaminated sampling tools are classified as hazardous waste and cannot be disposed of arbitrarily according to national regulations, resulting in high costs and significant waste. Summary of the Invention

[0003] The purpose of this invention is to provide an oil dipstick and a matching oil sampling bottle to eliminate the need for plastic tubing and syringes, thereby saving sampling costs.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This invention discloses an oil dipstick and a matching oil sampling bottle, comprising a sampling bottle, an oil dipstick, and an oil dipstick stopper. The sampling bottle has a telescopic design for its body and a conical design for its cap. First positioning pins are symmetrically arranged on both sides of the cap's outer side along its center line. The heads of the first positioning pins are spherical with a diameter slightly larger than the pin itself. The cap has a central through-hole with a threaded top. A first pull ring is located at the bottom of the sampling bottle, and a bolt is detachably connected to the pull ring and is used to mate with the threaded connection.

[0006] Furthermore, the oil measuring part of the dipstick is a hollow tubular design, and a conical hole is opened at the top of the dipstick. A groove is symmetrically arranged on the outer wall of the conical hole along the center of the conical hole.

[0007] Furthermore, the main body of the water jet dipstick is conical, which can be adapted to seal with the conical hole. A second positioning pin, identical to the first positioning pin, is provided along the axis of the conical shape, and a second pull ring is provided at the top of the dipstick.

[0008] Furthermore, the conical design of the bottle cap is exactly the same as the conical body of the dipstick plug.

[0009] Furthermore, the bolt is connected to the first pull ring through a weak link.

[0010] Furthermore, the bolt is snapped into place with the first pull ring.

[0011] Furthermore, the bolt is threadedly connected to the first pull ring.

[0012] Compared with the prior art, the beneficial technical effects of the present invention are as follows:

[0013] With the oil dipstick and matching oil sampling bottle of this application, when taking a sample, you only need to remove the dipstick stopper, flatten the sampling bottle to expel the air, screw it into the conical cavity of the dipstick, and then pull the first pull ring at the bottom of the sampling bottle to draw the oil sample. After the sampling is completed, remove the detachable bolt on the first pull ring and screw it into the bottle mouth. The whole process only uses one sampling bottle, which greatly saves sampling consumables. Attached Figure Description

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0022] refer to Figure 1 , Figure 2 , Figure 3An oil dipstick and matching oil sampling bottle, comprising: a sampling bottle (1), an oil dipstick (2), and an oil dipstick plug (3), wherein the body of the sampling bottle (1) is telescopic and the cap (14) is conical, and the outer side of the cap (14) is symmetrically provided with first positioning pins (141) on both sides of the center line, the head of the first positioning pin (141) is spherical with a diameter slightly larger than the first positioning pin (141), the cap (14) has a through hole (142) in the middle, the top of the through hole is provided with a thread (143), the bottom of the sampling bottle is provided with a pull ring (12), and a bolt (13) is provided in the middle of the pull ring, the bolt (13) is connected to the pull ring (12) through a weak link (131), and the bolt (13) and the thread (143) are matched.

[0023] With the above structure, the air can be expelled by flattening the bottle body, oil can be drawn in by pulling the pull ring, and the sampling bottle can be sealed by removing the bolt, thus replacing the use of a syringe to draw liquid.

[0024] refer to Figure 4 The oil measuring part of the dipstick (2) is a hollow tubular design (21). The top of the dipstick (2) has a conical hole (23), and the outer wall of the conical hole (23) is symmetrically provided with a groove (22) along the center of the conical hole.

[0025] The above structure allows for the use of a hollow tubular dipstick to draw oil from the oil level instead of a plastic hose. The groove design can lock the dipstick stopper and the mouth of the sampling bottle.

[0026] refer to Figure 5 The oil dipstick plug (3) has a conical body, which can be sealed with the conical hole (23). A second positioning pin (33) identical to that of (141) is set along the axis of the conical hole, and a second pull ring (32) is set on the top of the oil dipstick plug (3).

[0027] The above structure design enables the oil dipstick to be sealed and locked after sampling.

[0028] refer to Figure 1 , Figure 5 The conical design of the bottle cap (14) is exactly the same as the conical body of the dipstick plug (3).

[0029] Working principle: When taking a sample, simply remove the dipstick stopper 3, flatten the sampling bottle to expel the air, and screw it into the conical cavity 23 of the dipstick. Then pull the first pull ring 12 at the bottom of the sampling bottle to extract the oil sample. After sampling, remove the bolt 13 connected to the weak link 131 on the first pull ring 12 and screw it into the bottle mouth. The whole process uses only one sampling bottle, which greatly saves sampling consumables.
