Description

Technical Field

[0001] This utility model relates to the field of guide rail protective cover technology, and in particular to a microporous polyurethane foam polymer guide rail protective cover. Background Technology

[0002] A guide rail is a groove or ridge made of metal or other materials that supports, fixes, and guides moving devices or equipment and reduces their friction. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. During the operation of machine tools, the guide rail may be scratched by various debris. These scratches will reduce the accuracy and life of the guide rail. It is necessary to effectively isolate these debris and protect the guide rail from scratches by a protective cover. A polyurethane protective cover is a protective device made of polyurethane material.

[0003] An existing guide rail protective cover (publication number: CN216882692U) uses a telescopic component at the bottom of the reinforcing plate. When installing the guide rail protective cover, the distance between the telescopic end of the telescopic component and the slide groove of the guide rail can be adjusted by telescopically extending and retracting the component. Although this allows the guide rail protective cover to adapt to guide rails of different widths, the telescopic cloth placed between two adjacent reinforcing plates causes the two adjacent reinforcing plates to move closer together when the guide rail moves and retracts the entire protective cover. This results in a large force between the two reinforcing plates, which cannot effectively buffer the reinforcing plates, thus affecting the overall performance of the protective cover. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a microporous polyurethane foam polymer guide rail protective cover.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A microporous polyurethane foam polymer guide rail protective cover includes a reinforcing plate, a polyurethane telescopic cover, and a second mounting block. The second mounting block is embedded in and connected to the top of the reinforcing plate. The polyurethane telescopic cover is fixedly installed on one side of the reinforcing plate. A fixing rod is fixedly installed on the second mounting block. The other end of the fixing rod away from the second mounting block is fixedly provided with a first mounting block. A first slider is movably installed on the fixing rod. A first spring is sleeved on the end of the fixing rod near the first mounting block. A buffer plate is provided on one side of the first slider. A telescopic tube is hinged between the buffer plate and the first slider.

[0007] As a further embodiment of this utility model, the two ends of the spring are respectively fixedly connected to the mounting block and the slider, and the buffer plates are symmetrically distributed on the reinforcing plate.

[0008] As a further embodiment of this utility model, a second spring is sleeved on one end of the fixing rod near the second mounting block, and one end of the second spring is fixedly connected to the second mounting block.

[0009] As a further embodiment of this utility model, a slider is fixedly provided at the end of the spring two away from the mounting block two, and the slider two is slidably connected to the fixing rod.

[0010] As a further embodiment of this utility model, a telescopic tube is hinged between the second slider and the buffer plate, and the first mounting block is embedded in the top of the reinforcing plate.

[0011] As a further embodiment of this utility model, a support strip one is fixedly installed on the inner wall of the reinforcing plate, a support strip two is provided on one side of the support strip one, and a reinforcing rib is fixedly installed between the support strip one and the support strip two, and the reinforcing rib is distributed at equal intervals on the inner wall of the reinforcing plate.

[0012] Compared with the prior art, this utility model has the following beneficial effects: When the guide rail drives the protective cover to retract as a whole, it pushes the two adjacent reinforcing plates closer to each other. Under the action of telescopic tube one and telescopic tube two, the two adjacent buffer plates first come into contact. The buffer plates move backward, pushing telescopic tube one and telescopic tube two to tilt in different directions respectively. The two sets of telescopic tubes further drive slider one and slider two to move closer to the two ends of the fixed rod respectively, thereby compressing spring one and spring two to produce deformation. The elasticity of spring one and spring two provides a buffering effect for the reinforcing plates during the retraction of the protective cover. Support strip one and support strip two are set inside the reinforcing plate, and support strip one and support strip two are fixed again by reinforcing ribs, which strengthens the connection and improves the stability of the guide rail protective cover.

[0021] Reference Figures 1-4 A microporous polyurethane foam polymer guide rail protective cover includes a reinforcing plate 1, a polyurethane telescopic cover 2, and a mounting block 3. The mounting block 3 is embedded in the top of the reinforcing plate 1. The polyurethane telescopic cover 2 is fixedly installed on one side of the reinforcing plate 1. A fixing rod 105 is fixedly installed on the mounting block 3. A mounting block 101 is fixedly installed at the other end of the fixing rod 105 away from the mounting block 3. A slider 104 is movably installed on the fixing rod 105. A spring 106 is sleeved on the end of the fixing rod 105 near the mounting block 101. A buffer plate 102 is provided on one side of the slider 104. A telescopic tube 103 is hinged between the buffer plate 102 and the slider 104.

[0022] In use, when the guide rail retracts the entire protective cover, it pushes the two adjacent reinforcing plates 1 closer together. Under the action of telescopic tube 103 and telescopic tube 202, the two adjacent buffer plates 102 first come into contact. The buffer plates 102 then move backward, pushing telescopic tube 103 and telescopic tube 202 to tilt in different directions. The two sets of telescopic tubes further drive slider 104 and slider 201 to move closer to the two ends of the fixed rod 105, thereby compressing spring 106 and spring 203 and causing deformation. The elasticity of spring 106 and spring 203 reduces the force generated when the two adjacent reinforcing plates retract. Inside the reinforcing plate 1, there are support bars 101 and 203, which are then fixed by reinforcing ribs 202, strengthening the connection and improving the stability of the guide rail protective cover.

[0023] In this embodiment, the two ends of the spring 106 are fixedly connected to the mounting block 101 and the slider 104, respectively, and the buffer plate 102 is symmetrically distributed on the reinforcing plate 1.

[0024] When in use, when two adjacent buffer plates 102 first come into contact, the first telescopic tube 103 and the second telescopic tube 302 provide initial buffering for the buffer plates 102, reducing the force of contraction.

[0025] In this embodiment, a spring 303 is sleeved on one end of the fixing rod 105 near the second mounting block 3, and one end of the spring 303 is fixedly connected to the second mounting block 3.

[0026] In use, when the buffer plate 102 moves backward and squeezes the two sets of telescopic tubes, the two sets of telescopic tubes push the slider 104 and the slider 201 to move respectively, and the two sets of sliders compress the spring 106 and the spring 203 respectively.

[0027] In this embodiment, a slider 301 is fixedly provided at the end of the spring 303 away from the mounting block 3, and the slider 301 is slidably connected to the fixing rod 105.

[0028] When in use, the elasticity of spring 106 and spring 303 is used to reduce the force generated between the reinforcing plates during contraction, thereby reducing the impact on the overall protective cover.

[0029] In this embodiment, a telescopic tube 302 is hinged between the second slider 301 and the buffer plate 102, and the first mounting block 101 is embedded in the top of the connecting reinforcing plate 1.

[0030] In use, the reinforcing plate 1 is equipped with support strip 1 201 and support strip 203 inside, which are used to improve the supporting force of the reinforcing plate 1.

[0031] In this embodiment, a support strip 201 is fixedly installed on the inner wall of the reinforcing plate 1, a support strip 203 is provided on one side of the support strip 201, and a reinforcing rib 202 is fixedly installed between the support strip 201 and the support strip 203. The reinforcing ribs 202 are evenly distributed on the inner wall of the reinforcing plate 1.

[0032] In use, multiple reinforcing ribs 202 further connect and fix the support bar 1 201 and the support bar 203, thereby strengthening the connection.

[0033] From the above description, it can be seen that the above-described embodiments of this utility model achieve the following technical effects: When the guide rail drives the protective cover to retract as a whole, it pushes the two adjacent reinforcing plates 1 closer to each other. Under the action of telescopic tube 103 and telescopic tube 202, the two adjacent buffer plates 102 first come into contact. The buffer plates 102 move backward, pushing the telescopic tube 103 and telescopic tube 202 to tilt in different directions respectively. The two sets of telescopic tubes further drive the slider 104 and slider 201 to move closer to the two ends of the fixed rod 105 respectively, thereby compressing the spring 106 and spring 203 to produce deformation. The elasticity of the spring 106 and spring 203 provides a buffering effect for the reinforcing plates during the retraction of the protective cover. The reinforcing plate 1 is provided with support strip 101 and support strip 203, and the support strip 101 and support strip 203 are fixed again by the reinforcing rib 202, which strengthens the connection and improves the stability of the guide rail protective cover.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
