Problems solved by technology

At present, an oil pan used in sewing machines is placed on the platen and cannot be moved with the head. When the machine head is turned up, the oil pan is exposed to the outside, which is prone to oil pollution, and the lubricating oil is also easily polluted by thread wool, etc.
There is also a kind of oil cap fixed on the bottom plate by screws, it is very inconvenient to unscrew the screws when disassembling

Embodiment 1

[0032] Embodiment 1: see figure 1 -8:

[0033] The snap-fit ​​connection structure between the oil pan and the bottom plate of the sewing machine includes a bottom plate 1 and an oil pan 2 arranged below the bottom plate 1 , and the oil pan 2 is detachably connected to the bottom plate 1 .

[0034] The above-mentioned detachable connection is: one end of the oil pan 2 is hingedly connected to one end of the bottom plate 4, and the other end is detachably connected to the other end of the bottom plate through buckles; or both ends of the oil pan 2 are connected to the bottom plate 1 through buckles. Removable connection at both ends. In this embodiment, one end of the oil pan 2 is hingedly connected to one end of the bottom plate 4 , and the other end is detachably connected to the other end of the bottom plate 4 through buckles.

[0035] One end of the above-mentioned oil pan 2 is hingedly connected to one end of the bottom plate 1: a hinge 3 is provided at one end of the bo...

Embodiment 2

[0041] Example 2: see Figure 9 -11:

[0042] The buckle structure of this embodiment is different from that of Embodiment 1:

[0043] The buckle can also be: include an elastic hook 14 arranged on the bottom plane of the base plate 1, such as: a hook made of plastic material, the hook 14 can be fixed on the base plate 1 by screws, corresponding to the hook on the oil pan 2 The position of 14 is provided with a convex edge 15, and the hook portion of the hook 14 is clamped on the convex edge 15 to securely connect the oil pan 2 and the bottom plate 1. The buckle structure can be respectively arranged on both sides of the oil pan 2 to connect with the bottom plate 1, and can also be combined with the above-mentioned hinge structure, so that one side of the oil pan 2 is hingedly connected with the bottom plate 1, and the other side is detachable through a buckle connect.

[0044] The opening method of this embodiment is:

[0045] The two ends of the oil pan 2 are connected t...

Abstract

The invention belongs to the technical field of sewing machines, and particularly relates to a connecting structure of a lacquer tray and a bottom plate of a sewing machine and an opening method thereof. The connecting structure comprises a bottom plate and the lacquer tray arranged below the bottom plate, wherein the lacquer tray is detachably connected with the bottom plate. One end of the lacquer tray is connected with one end of the bottom plate through a hinge; the other end of the lacquer tray is detachably connected with the other end of the bottom end through a buckle, or both two ends of the lacquer tray are detachably connected with both ends of the bottom plate through buckles. The connecting structure is novel in structure; the lacquer tray and the bottom plate can be connected together, and the lacquer tray can be conveniently separated from the bottom plate when needed; the connecting structure is simple and convenient to operate, and can be assembled and disassembled without other tools; the working efficiency is improved.

Description

Technical field: [0001] The invention belongs to the technical field of sewing machines, in particular to a connection structure between an oil pan and a bottom plate of a sewing machine and an opening method thereof. Background technique: [0002] The oil pan provided on the lockstitch sewing machine is used to receive oil, and the oil pan is installed under the bottom plate. In order to facilitate the oil pan to be transported together with the machine, the oil pan needs to be fixed to the bottom plate. A kind of oil pan that sewing machine uses is placed on the platen at present, can not move together with head, and when machine head turns over, oil pan is exposed to the outside, easily produces oily dirt, and lubricating oil is also easily polluted by wool etc. Another kind of oil cover is fixed on the bottom plate by screws, and the screws need to be unscrewed when dismounting, which is very inconvenient. Invention content: [0003] The object of the present inventi...
