Abstract

(57) [Summary] [Purpose] To provide a structure that allows the cover of a machine such as a conveyor to be attached without the need to tighten and remove bolts. [Structure] The cover mounting structure 20 is formed by bending a mounting pin 23 provided with a collar 22 and standing on a mounted frame 21 and an end of a cover 24 mounted on the mounted frame 21 into a U-shaped cross section. The bent piece 25 has an engaging slit 26 formed in the bent piece and having a width wider than the outer diameter of the mounting pin 23 and narrower than the outer diameter of the collar 22. In the cover 24, when the engaging slit 26 is inserted into the mounting pin 23, the bent frame 25 and the attached frame 21 and the collar 2 are inserted at the bent piece 25.
2 and the engaging slit 26 has the mounting pin 23.
It is adapted to be attached to the mounted frame 21 by being hooked on. Since the cover 24 is attached to the attached frame 21 at the bent piece 25 that is bent in a U-shaped cross section, the cover 24 is attached to the attached frame 21 while covering the attachment pins 23.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure that allows a cover of a machine such as a conveyor to be attached without the need to tighten and remove bolts.

[0002]

[Prior art]

 Conventionally, for example, as shown in FIG. 6, a frame for accommodating a belt conveyor motor, drive rollers, etc. (hereinafter referred to as “attached frame”) is inspected for a motor, drive rollers, etc. (not shown). A cover 11 is removably attached by a mounting bolt 10 so that the above can be performed.

[0003]

[Problems to be solved by the device]

 However, when the cover 11 is attached to the attached frame 12 in this manner, all the attachment bolts 10 must be removed when removing the cover 11. Therefore, this structure has problems that it takes time to remove the cover, the mounting bolt 10 may be lost, and the head of the mounting bolt 10 is exposed to the outside, which is dangerous. is doing.

[0004]

[Means for Solving the Problems]

 The present invention is, firstly, a mounting pin that is provided upright on a frame to be mounted with a collar, and a bent piece that is formed by bending an end of a cover that is mounted on the frame to be mounted into a U-shaped cross section. Secondly, by the mounting structure having an engaging slit formed on the bent piece and having a width wider than the outer diameter of the mounting pin and narrower than the outer diameter of the collar, secondly, the collar is provided so as to be movable in the axial direction. A mounting pin that is erected on the mounting frame, an elastic body that urges the collar toward the mounted frame, and a width that is formed on a cover that is mounted on the mounted frame and has a width wider than the outer diameter of the mounting pin. The above-mentioned problem is solved by the mounting structure having the engagement slit narrower than the outer diameter of the collar.

[0005]

[Action]

 In the first mounting structure, when the engaging slit portion is inserted into the mounting pin and the cover is moved along the engaging slit, the bent piece is sandwiched between the mounting frame and the flange, and the mounting frame is covered. Is to be installed. Moreover, since the cover is attached to the frame to be attached at the bent pieces bent in a U-shaped cross section, it is attached to the frame to be attached while covering the attachment pins.

In the second mounting structure, when the engaging slit portion is inserted into the mounting pin and the cover is moved along the engaging slit, the portion where the engaging slit is formed becomes the mounted frame and the collar. The cover is sandwiched and attached to the frame to be attached. In addition, the cover is pressed by the brim that is urged by the elastic body and is pressed against the mounted frame.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. The cover mounting structure 20 includes a mounting bolt (mounting pin) 23 screwed into a mounting frame 21 and provided with a collar 22, and a bent piece 25 formed by bending an end portion of the cover 24 into a U-shaped cross section. An engaging slit 26 formed in the bent piece 25 has a width W (see FIG. 5) wider than the outer diameter D1 of the mounting bolt 23 and narrower than the outer diameter D2 of the collar 22. The collar 22 is loosely fitted to the mounting bolt 23 and is urged toward the mounted frame 21 by a spring (elastic body, see FIG. 1) 27. The brim 22 is formed with a receiving piece 30 that receives the spring 27. In FIG. 1, a hole 28 for receiving the collar 22 is continuously formed in the lower slit 26.

Next, a procedure for attaching the cover 24 will be described. First, the engaging slit 26 is inserted into the mounting bolt 23. The bent piece 25 is sandwiched between the mounted frame 21 and the flange 22, and the engaging slit 26 is hooked on the mounting bolt 23. Further, since the bent piece 25 is formed by bending it into a U-shaped cross section, the cover 24 can cover the mounting bolt 23. Moreover, the bent piece 25 is pressed by the collar 22 urged by the spring 27 and pressed against the mounted frame 21.

The cover mounting structure 20 can also be provided on both the left and right sides of the cover 24. In this case, the cover 24 can be attached and detached by moving the cover 24 in the left-right direction.

[0010]

[Effect of device]

 According to the mounting structure of claims 1 and 2, the cover can be mounted without removing the mounting pin. Therefore, it is not necessary to use a tool, the time required for attaching and detaching the cover can be shortened, and the attachment pin can be prevented from being lost. In the mounting structure according to the first aspect, the cover is mounted on the mounting frame by bending the U-shaped cross section. Therefore, the cover can cover the mounting pin, and the danger due to the exposed mounting pin can be avoided. In the mounting structure of claim 2, the cover is pressed against the mounted frame by the elastic body. This saves the trouble of tightening the bolts and bringing the cover into close contact. Further, since the cover is pressed against the attached frame by the elastic body, even if the attached frame vibrates, it is possible to prevent the cover from coming off and to make the cover less likely to resonate.
