Description

Technical Field

[0001] The utility model relates to the field of textile equipment, and more particularly to a durable sewing machine. Background Art

[0002] A sewing machine is a mechanical device used to sew cloth, leather and other materials to connect or decorate them. It uses a combination of needle and thread to sew various materials together to make, repair or decorate clothes. It is widely used in the clothing, home furnishing, luggage and other industries.

[0003] Existing sewing machines are all equipped with an oil pan, which usually stores oil. The oil level will gradually decrease with the use time. When the oil level drops to the lowest scale line of the oil pan, it is necessary to refuel. The existing way to check the oil level is to flip the machine body up to check, which is less convenient.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a durable sewing machine.

[0006] The above technical objectives of the present utility model are achieved through the following technical solutions: a durable sewing machine includes a machine base, an oil pan is provided on the machine base, a cover for closing the oil pan is rotatably connected to the machine base, an organism is fixedly connected to the cover, an observation port is provided on the cover, a closing plate for closing the observation port is slidably connected to the cover, and a fixing mechanism for fixing the closing plate is provided on the cover.

[0007] The utility model is further configured as follows: a plurality of limiting strips are fixedly connected to the cover plate, the cross section of the limiting strips is L-shaped, and the closing plate slides on the limiting strips.

[0008] The utility model is further configured as follows: the fixing mechanism includes a buckle and a slot, the buckle is slidably connected to the cover plate, and the slot is located on the closing plate.

[0009] The utility model is further configured as follows: a sliding hole for sliding of the buckle is opened on the cover plate, a limiting portion is fixedly connected to the buckle, and a compression spring is provided between the limiting portion and the cover plate.

[0010] The utility model is further configured as follows: a positioning strip is fixedly connected to the closing piece.

[0011] The utility model is further configured such that: the length of the positioning strip is greater than the thickness of the cover sheet.

[0012] The utility model is further configured as follows: the closing piece is made of transparent material.

[0013] The utility model is further configured as follows: the cover plate is made of stainless steel.

[0014] In summary, the present invention has the following beneficial effects:

[0015] By arranging an observation port on the cover, the oil level in the oil pan can be observed through the observation port without flipping up the cover. At the same time, a sliding closing piece on the cover can close the observation port to prevent external impurities from entering the oil pan. At the same time, the fixing mechanism can allow the closing piece to keep the observation port closed. When the oil pan needs to be maintained, the cover can still be flipped up to expose the oil pan for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] Durable sewing machine, such as Figures 1 to 4As shown, it includes a machine base 1, an oil pan 2 is provided on the machine base 1, a cover piece 3 for closing the oil pan 2 is rotatably connected to the machine base 1, an organism 4 is fixedly connected to the cover piece 3, an observation port 5 is provided on the cover piece 3, a closing piece 6 for closing the observation port 5 is slidably connected to the cover piece 3, and a fixing mechanism for fixing the closing piece 6 is provided on the cover piece 3. By setting the observation port 5 on the cover piece 3, the oil amount in the oil pan 2 can be observed through the observation port 5 without turning up the cover piece 3. At the same time, the closing piece 6 sliding on the cover piece 3 can close the observation port 5 to prevent external impurities from entering the oil pan 2. At the same time, the fixing mechanism can allow the closing piece 6 to keep the observation port 5 closed, and when the oil pan 2 needs to be maintained, the cover piece 3 can still be turned up to expose the oil pan 2 for maintenance. The cover piece 3 is made of stainless steel, which has good corrosion resistance and strength, thereby improving the service life of the cover piece 3.

[0023] like Figure 2 、 Figure 3 and Figure 4 As shown, two limiting strips 7 are welded on the cover piece 3, and the cross-section of the limiting strip 7 is L-shaped. The closing piece 6 slides on the limiting strip 7, so that the limiting strip 7 can limit the closing piece 6, and realize the sliding of the closing piece 6 on the cover piece 3. The fixing mechanism includes a buckle 8 and a slot 9. The buckle 8 is slidably connected to the cover piece 3, and the slot 9 is located on the closing piece 6. When the buckle 8 is inserted into the slot 9 on the closing piece 6, the closing piece 6 is fixed. A sliding hole 10 for the sliding of the buckle 8 is opened on the cover piece 3. A limiting part 11 is fixed to the buckle 8 by screws. A compression spring 12 is provided between the limiting part 11 and the cover piece 3. The compression spring 12 can provide the buckle 8 with a force to keep the buckle 8 in the slot 9, thereby realizing the long-term fixation of the closing piece 6 by the fixing mechanism.

[0024] like Figure 1 and Figure 4As shown, a positioning strip 13 is fixedly connected to the closing piece 6. By setting the positioning strip 13, the positioning strip 13 can limit the sliding of the closing piece 6. The length of the positioning strip 13 is greater than the thickness of the cover piece 3, so that it is convenient for the user to slide the closing piece 6. The closing piece 6 is made of polystyrene material, which has transparent properties. Therefore, when the closing piece 6 closes the observation port 5, the user can still observe the oil level in the oil pan 2. When it is necessary to open the observation port 5 for further observation, the user presses the limiting portion 11. Since there is a compression spring 1 between the limiting portion 11 and the cover piece 3 2, so that the compression spring 12 is elastically deformed and its length becomes shorter. During this process, the buckle 8 slides in the sliding hole 10, and the buckle 8 gradually slides out of the slot 9. When the buckle 8 is completely moved out of the slot 9, the user detents the positioning bar 13, so that the closing piece 6 slides on the limit bar 7, and the observation port 5 can be opened, so that the user can further observe the oil amount in the oil pan 2. At the same time, the user can refuel in time through the observation port 5. When the user observes that there are more impurities in the oil pan 2, the user can flip up the cover piece 3, so that the oil pan 2 can be maintained.

[0025] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
