Description

Technical Field

[0001] The utility model relates to the field of dust removal, in particular to a novel door buckle. Background Art

[0002] The manhole inspection door on the top of the dust collector is an indispensable component of the dust collector. There are at least a dozen and at most hundreds of this component. Each manhole inspection door is generally equipped with 10 door catches, which are generally tightened with bolts. The bolts are exposed to the external environment for a long time and are easily corroded. As a result, each time the top is inspected, it is time-consuming and labor-intensive to open the manhole inspection door. With the increase of years of use and the number of times the manhole inspection door is opened, the bolts gradually become unusable due to rust. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] like Figure 1-4 As shown, the utility model proposes a new type of door buckle, the buckle plate mechanism includes a buckle plate seat 11, a bent buckle plate 12 is arranged on the top of the buckle plate seat 11, and a mounting plate 13 attached to the inspection door is arranged on the back;

[0024] A mounting frame 2 attached to the inspection door frame is provided above the mounting plate 13;

[0025] The handle mechanism includes an axis frame 31 installed in the mounting frame 2, and a rotatable shaft 32 is installed in two axis holes of the axis frame 31 respectively, and a clamping plate 33 is sleeved on the outside of the shaft 32, and a handle 34 is connected to the distal end of the two clamping plates 33;

[0026] The hanging buckle mechanism includes a hanging rod shaft 41 rotating along the axial hole of the clamping plate 33, a hanging rod 42 is installed in the middle of the hanging rod shaft 41, and the other end of the hanging rod 42 is connected to a hanging buckle 43 matched with the buckle plate 12.

[0027] It should be noted that the clamping plate 33 is a first rotating part, which is controlled by the shaft 32 rotating in the shaft frame 31 ; the suspension rod 42 is a second rotating part, which is controlled by the suspension rod shaft 41 rotating on the clamping plate 33 .

[0028] In this embodiment, when the door buckle is closed, the grip handle 34 is pushed upward, and the clamping plate 33 rotates with the shaft rod 32 in the shaft hole of the shaft frame 31, driving the hanging buckle mechanism to lift upward. During the process of pressing the hanging buckle 43 downward, the hanging rod 42 rotates downward with the hanging rod shaft 41 in the shaft hole of the clamping plate 33, and the hanging buckle 43 is inserted into the groove of the buckle plate 12. Subsequently, the handle mechanism is pushed upward again, so that the hanging buckle 43 and the buckle plate 12 are closely attached. The similar buckle design can realize the reinforcement between the inspection door and the inspection door frame;

[0029] When opening the door buckle, just operate in the reverse direction, eliminating the need for the bolt structure to lock the door buckle, and solving the problem of the door buckle being difficult to open and close due to rust.

[0030] It can be understood that the hanging buckle 43 is a "triangular" structure, which has high stability and is not easily deformed when pulled, thereby ensuring that the hanging buckle 43 is tightly attached to the inside of the buckle plate 12.

[0031] As an installation example of the pinch plate mechanism: the mounting plate 13 is an "L-shaped" structure, and a number of bolts connecting the inspection door are passed through the pinch plate seat 11 and the mounting plate 13, and the pinch plate seat 11 is fixed to the inspection door by four bolts at the corners.

[0032] As an installation example of the handle mechanism: the mounting frame 2 is a "U-shaped" structure, and a number of bolts connecting the inspection door frame are passed through the mounting frame 2 and the shaft frame 31. The mounting frame 2 and the shaft frame 31 are installed on the inspection door frame by four bolts, and the bolts are not shown in the figure.

[0033] In an optional embodiment, a pin end seat 51 is provided on one side of the boom shaft 41 that passes through the splint 33, and a pin 52 for reinforcement passes through the pin end seat 51; the pin 52 is inserted into the pin end seat 51, and the protruding section of the pin 52 abuts against the side wall of the splint 33, thereby limiting the rotation of the boom shaft 41 and keeping the boom 42 suspended at a specified position.

[0034] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation on the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the claims attached to the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the attached claims, or the equivalent forms of such scope and boundaries.
