Description

Technical Field

[0001] The utility model relates to the field of brake technology, in particular to an integrated wet brake which is oil-leakage-proof. Background Art

[0002] The brake is a device that can slow down, stop and keep the moving parts in a stopped state, and is usually composed of a brake frame, a brake member and an operating device. For example, an energy-saving wet brake with a publication number of "CN220540171U" is used. After the oil is filled through the oil filling hole, the sealing bolt is screwed into the inside of the oil filling hole. When it is screwed to the bottom, the limit plate is inserted into the inside of the slot hole, and the shaped groove is inserted into the inside of the annular groove and the limit plate is fixed by the fixing bolt, so that the position of the sealing bolt is limited by the cooperation of the shaped groove on the limit plate and the annular groove, thereby avoiding the occurrence of oil leakage due to the loosening of the sealing bolt;

[0003] When the above mechanism is in use, the limit plate is inserted into the slot and fixed with a fixing bolt, but the staff needs to use a tool to tighten the fixing bolt to fix the limit plate, which makes the operation time-consuming and labor-intensive and inconvenient to use. At the same time, after the sealing bolt is used for a long time, the thread on its surface will wear and there will be a certain gap with the oil filling port, which reduces the sealing effect of the oil filling port and causes oil leakage.

[0004] Therefore, we proposed an anti-oil leakage integrated wet brake that can solve the above problems well. Utility Model Content

[0016] Compared with the prior art, the utility model has the following beneficial effects: the oil leakage-proof integrated wet brake adopts a new structural design, the specific contents of which are as follows:

[0017] (1) After the oil filling port is filled with oil, the sealing bolt is screwed into the oil filling port. At this time, the fitting block is squeezed and moved, and the limiting half ring and the movable rod are moved and the second spring is squeezed. Then, with the elastic force of the second spring, the limiting half ring always tends to move toward the sealing bolt, and the sealing bolt can be clamped and fixed, thereby improving the sealing performance of the connection between the sealing bolt and the oil filling port, and preventing the sealing bolt from loosening after long-term use and causing oil leakage;

[0020] (3) When the driving rod is pulled, the driving rod drives the push plate to move, and at the same time the moving block moves and squeezes the limit block, so that the limit block moves and squeezes the third spring. Then, when the moving block moves to the other side of the limit block, the limit block resets under the elastic force of the third spring and limits the moving block. At this time, the push plate is positioned forward so that the braking force can be adjusted, thereby pressing the brake pad through the push plate to make the braking effect more sensitive.
