Description

Technical Field

[0001] The utility model relates to the technical field of coupling covers, and in particular to an adjustable quick-open coupling cover. Background Art

[0002] Multi-stage centrifugal blowers use a coupling to drive the main engine and motor, so a coupling guard is a must-have protective device for every blower. To ensure the safety of on-site operators and facilitate on-site installation and removal, the radial length of the coupling guard is particularly important.

[0003] Currently, existing coupling protective covers are usually integral structures with fixed and non-adjustable axial and radial lengths, making it difficult to adapt to couplings of different specifications or installation heights. They often only cover the maximum diameter of the coupling, and the length of the coupling is less than the total length of the couplings at both ends, and cannot form a full seal. As a result, rotating parts are exposed at the bottom and both ends of the coupling, limiting the versatility and flexibility of the protective cover. Utility Model Content

[0004] The utility model proposes an adjustable quick-open coupling cover. Through the relative sliding connection between a fixed cover body and a movable cover body, the total length between the two can be conveniently adjusted to adapt to couplings of different sizes, ensuring that the coupling can be fully enclosed and protected, and effectively blocking the erosion of the coupling by harmful factors such as external dust, moisture, and oil stains.

[0005] To this end, the technical solutions adopted are as follows:

[0006] An adjustable quick-open coupling cover includes a fixed cover body, a movable cover body and a support member. The fixed cover body can be horizontally slid and nested on the outside of the movable cover body. A connecting member is installed at the bottom of the fixed cover body, and the connecting member includes a vertical plate fixed to the bottom of the fixed cover body; the support member includes a horizontally arranged bottom plate, and the top of the bottom plate is fixed with a vertically arranged support plate on both sides of the vertical plate, and the vertical plate and the support plates on both sides can be slidably connected up and down.

[0007] A further technical solution is that the connecting part also includes a connecting plate fixed to the top of the vertical plate, the fixed cover body is formed by two first half covers that are rotated upward and buckled through the rotating shaft at the bottom, and the rotating shaft can be rotatably connected to the connecting plate; the movable cover body is formed by two second half covers that are buckled together, and the outer side of each second half cover is threadedly connected to a first adjusting bolt, and a horizontally arranged first guide groove is opened on the outer side wall of the two first half covers, and the two second half covers are respectively attached to the two first half covers and the first adjusting bolt on each second half cover passes through the first guide groove on the first half cover to which it is attached and is locked.

[0008] A further technical solution is that the buckling part of the two second half covers has a positioning mechanism, which includes a positioning block fixed on one of the second half covers and a positioning groove provided on the other second half cover and adapted to the positioning block.

[0009] A further technical solution is that the support member includes a second adjusting bolt, a second guide groove is provided on the support plate, and the second adjusting bolt passes through the second guide groove and is threadedly connected to the vertical plate.

[0010] A further technical solution is that a slider is fixed on the side wall of the vertical plate, and a slider matching the slider and arranged up and down is provided on the support plate.

[0011] The working principle and beneficial effects of this application are:

[0012] 1. Through the relative sliding connection between the fixed cover and the movable cover, the total length between the two can be easily adjusted to adapt to couplings of different sizes, ensuring that the coupling can be fully enclosed and protected, effectively blocking the erosion of the coupling by harmful factors such as external dust, moisture, oil stains, etc.

[0013] 2. The vertical plate can be displaced vertically along the support plate. This design allows the height of the fixed cover and the movable cover to be flexibly adjusted, ensuring that their axes precisely coincide with the axis of the coupling. It can be used for the installation of couplings at different heights, enhancing the versatility and adaptability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 5 As shown, an adjustable quick-open coupling cover includes a fixed cover body 1, a movable cover body 2 and a support member 4. The fixed cover body 1 can be horizontally slid and nested on the outside of the movable cover body 2. A connecting member 3 is installed at the bottom of the fixed cover body 1. The connecting member 3 includes a vertical plate 31 fixed to the bottom of the fixed cover body 1; the support member 4 includes a horizontally arranged bottom plate 41, and the top of the bottom plate 41 is fixed with a vertically arranged support plate 42 on both sides of the vertical plate 31, and the vertical plate 31 and the support plates 42 on both sides can be slidably connected up and down.

[0023] In this embodiment, this scheme is a device for protecting the coupling used between the main unit and the motor of a multi-stage centrifugal blower, which is used to protect the coupling from external factors. Specifically, the fixed cover body 1 and the movable cover body 2 are relatively slidably connected, so that the total length between the fixed cover body 1 and the movable cover body 2 can be adjusted, so that it can be adjusted according to installation requirements to achieve fully enclosed protection of the coupling. In addition, the vertical plate 31 can be vertically displaced along the support plate 42, so that the height of the fixed cover body 1 and the movable cover body 2 can be adjusted, and the axis of the fixed cover body 1 and the movable cover body 2 can be coincided with the axis of the coupling, so as to be suitable for coupling installation work at different heights.

[0024] like Figure 3-Figure 5As shown, the connecting member 3 also includes a connecting plate 32 fixed to the top of the vertical plate 31, and the fixed cover body 1 is formed by two first half covers 11 rotating upward through the rotating shaft at the bottom, and the rotating shaft is rotatably connected to the connecting plate 32; the movable cover body 2 is formed by two second half covers 21 buckled together, and the outer side of each second half cover 21 is threadedly connected to the first adjusting bolt 22, and a horizontally arranged first guide groove 12 is provided on the outer side wall of the two first half covers 11, and the two second half covers 21 are respectively attached to the two first half covers 11 and the first adjusting bolt 22 on each second half cover 21 passes through the first guide groove 12 on the first half cover 11 to which it is attached and is locked.

[0025] In this embodiment, by rotating a pair of first half covers 11 and connecting them to both sides of the connecting plate 32 respectively, the two first half covers 11 can synchronously drive the two second half covers 21 to unfold, so that the fixed cover body 1 and the movable cover body 2 can be sleeved on the outer enclosure of the coupling to achieve the purpose of quick opening and disassembly. In addition, the pair of second half covers 21 can be controlled to move in the axial direction. At this time, the first adjusting bolt 22 slides in the first guide groove 12. When the second half cover 21 moves to a certain position, the second half cover 21 can be fixed by tightening the first adjusting bolt 22.

[0026] Among them, a pair of first half covers 11 are connected by fasteners, and the fasteners can be connected by snap fastening or bolt connection to achieve the connection of the pair of first half covers 11, that is, when the pair of first half covers 11 are combined into a complete circular shape, the pair of first half covers 11 are fixed by fasteners.

[0027] It should be noted that the pair of second half covers 21 are coaxially arranged with the pair of first half covers 11 after they are closed.

[0028] like Figure 3 As shown, the buckling portion of the two second half covers 21 has a positioning mechanism, which includes a positioning block 23 fixed on one of the second half covers 21 and a positioning groove provided on the other second half cover 21 to match the positioning block 23 .

[0029] In this embodiment, when a pair of first half covers 11 rotate to a closed state, the pair of second half covers 21 are synchronously driven to close, so that the positioning block 23 on one side of one second half cover 21 is inserted into the positioning groove on the side of the other second half cover 21. Therefore, when one of the second half covers 21 is controlled, the pair of second half covers 21 can be synchronously driven to move axially.

[0030] like Figure 5As shown, the support member 4 includes a second adjustment bolt 44. The support plate 42 defines a second guide slot 43. The second adjustment bolt 44 passes through the second guide slot 43 and is threadedly connected to the vertical plate 31. A slider 311 is fixed to the side wall of the vertical plate 31, and the support plate 42 defines a slider 312 that matches the slider 311 and is arranged above and below the slider 311.

[0031] In this embodiment, by controlling the vertical plate 31 to slide between a pair of support plates 42, the second adjusting bolt 44 is synchronously driven to move in the second guide groove 43. When the fixed cover body 1 and the movable cover body 2 on the top of the connecting member 3 move to a certain height, the vertical plate 31 can be fixed by tightening the second adjusting bolt 44 to achieve the purpose of locking.

[0032] Working principle:

[0033] First, the pair of first half covers 11 are rotatably connected to the two sides of the connecting plate 32 respectively, so that the two first half covers 11 can synchronously drive the two second half covers 21 to unfold and move to the lower position of the coupling. The bottom plate 41 is fixed to the installation platform by using bolts, and the fixed cover body 1 and the movable cover body 2 are closed and sleeved on the outer enclosure of the coupling. By controlling the vertical plate 31 to slide between the pair of support plates 42, the second adjusting bolt 44 is synchronously driven to move in the second guide groove 43. The height of the fixed cover body 1 and the movable cover body 2 is adjusted according to the installation requirements, and the axis of the fixed cover body 1 and the movable cover body 2 is coincided with the axis of the coupling. Then, the vertical plate 31 can be fixed by tightening the second adjusting bolt 44. Finally, the pair of second half covers 21 can be controlled to move in the axial direction. At this time, the first adjusting bolt 22 slides in the first guide groove 12 to adjust the total length between the fixed cover body 1 and the movable cover body 2, so that it can be adjusted according to the installation requirements to achieve full enclosed protection of the coupling. The second half cover 21 can be fixed by tightening the first adjusting bolt 22.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
