[0043] In actual application, the first protective cover 20 can be increased or decreased according to the actual length of the equipment.

[0044] The existing guide rail protection cover includes a protection cover shell, a telescopic layer and a support frame. The telescopic layer is composed of multiple layers, and two adjacent layers are connected by scissor-type components. The scissor-type components have a complex structure and the layers are closely connected. When the equipment runs at a speed exceeding 40m / min, a lot of noise will be generated. In order to solve the above technical problems, please refer to Figures 1 to 7 As shown, the first protective cover 20 and the second protective cover 10 are both provided with bent ends;

[0045] The first protective cover 20 and the second protective cover 10 arranged at the position of the slider are both welded with a connecting piece 60, and a connecting plate 70 is arranged in the connecting piece 60, and at least two groups of rolling components 702 are arranged on the connecting plate 70 near the bending end position, and the rolling components 702 are in rolling contact with the adjacent bending end.

[0046] In this embodiment, the utility model has a simple overall structure and is relatively easy to install. By adding a rolling component, when the first protective cover 20 is extended and retracted inside the second protective cover 10, the rolling component 702 is brought into rolling contact with the adjacent bent end 70 to generate rolling friction, thereby preventing the generation of loud noise.

[0047] See also Figure 3 As shown, the rolling assembly 702 includes a roller seat 7024, and a slot 7023 for the connecting plate 70 to be inserted into is opened on the roller seat 7024, and the roller seat 7024 is fixedly installed on the connecting plate 70 by fastening screws.

[0048] Furthermore, a connecting shaft 7022 is provided on the roller seat 7024 near the bending end, and a roller 7021 is provided on the connecting shaft 7022, and the bottom end of the roller 7021 is in conflict with the top end of the wheel groove at the bending end.

[0049] In this embodiment, when the first protective cover 20 is pulled, the slider 40 arranged on the first protective cover slides in the guide rail 50 arranged on its adjacent protective cover (the second protective cover). When the first protective cover 20 is sliding, the roller 7021 of the rolling assembly 702 arranged in the first protective cover 20 rolls in the wheel groove of the bent end, so that when the rolling assembly 702 rolls with the adjacent bent end 70, rolling friction is generated, thereby preventing the generation of loud noise.

[0050] In actual application, when the roller is damaged, in order to facilitate the replacement of the roller, please refer to Figure 2 and Figure 4 As shown,

[0051] The connecting plate 70 is made of a stainless steel plate, and the other end of the connecting plate 70 is inserted into a slot of the connecting block 701 , thereby achieving connection between the connecting block 701 and the connecting plate 70 .

[0052] Furthermore, the inner wall of the connecting member 60 is provided with a limiting groove 601 for the two side walls of the connecting plate 70 to extend into, and a snap connection is performed.

[0053] The first protective cover 20, the second protective cover 10 and the connecting piece 60 are all provided with threaded holes, and fasteners 30 are arranged in the threaded holes, and the connection between the connecting piece 60 and its adjacent protective cover (the first protective cover 20, the second protective cover 10) is achieved through the fasteners 30; the fastener 30 includes a screw rod 302, and the screw rod 302 passes through the threaded holes on the protective cover (the first protective cover or the second protective cover) and the connecting piece 60 in turn, and a fastening seat 303 is welded on the end face of the screw rod 302 extending out of the threaded hole, and a clamp 304 is welded on the end face of the fastening seat 303 away from the screw rod 302, and a spring 301 is arranged on the clamp 304, and the other end of the spring 301 is fixedly installed in the clamping groove 7011.

[0054] Furthermore, the card member 304 is inserted into the card slot 7011 to perform a card-engagement connection.

[0055] In this embodiment, during installation, it is only necessary to rotate the screw 302 of the fastener, and the screw 302 is continuously screwed out of the threaded hole, and drives the clamp 304 to extend into the clamping groove 7011 for clamping connection; at the same time, by tightening the fastening nut on the fastener, the connection between the connector and the protective cover is achieved.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not restrictive. Although the utility model is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
