Description

Technical Field

[0001] This utility model belongs to the field of mechanical engineering technology, specifically a protective cover for a vacuum pump unit coupling. Background Technology

[0002] During the operation of a vacuum pump unit, the coupling is a key component, and its normal operation is crucial to the stability and efficiency of the entire unit. However, in actual operation, the coupling is often exposed to the outside and is easily affected by external factors, such as accidental collisions, which may damage the coupling and thus affect the normal operation of the vacuum pump unit. In addition, traditional protective measures often have certain limitations. For example, the protective device may be too bulky, affecting the normal work of the operator, or the structure of the protective device may not be flexible enough to effectively buffer external forces, resulting in poor protective effect. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a protective cover for the coupling of a vacuum pump unit, which solves the problems that traditional protective measures may be too bulky, affecting the normal work of operators, or that the structure of the protective device is not flexible enough and cannot effectively buffer external forces, resulting in poor protective effect.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective cover for a vacuum pump unit coupling, comprising a protective plate, wherein a plurality of support mechanisms are uniformly and equidistantly arranged on the outer wall of the protective plate, each support mechanism comprising a fixing frame, wherein there are two fixing frames, the two fixing frames being fixedly connected to the outer wall of the protective plate, a support column being fixedly installed between the inner walls of the fixing frames, a support slider being slidably connected to the outer wall of the support column, a compression spring being sleeved on one side of the outer wall of the support column located on the support slider, and a support rod being fixedly connected to the opposite side of the two support sliders.

[0005] As a further embodiment of this utility model: the outer wall of the protective plate is provided with several through holes, and two connecting plates are fixedly connected to both ends of the protective plate.

[0006] As a further embodiment of this utility model: two fixing plates are fixedly connected to one side of the connecting plate, and two fixing components are respectively provided on the opposite side of the two fixing plates, with the two fixing components facing each other.

[0007] As a further embodiment of this utility model: the fixing component includes an outer frame, which is fixedly connected to the fixing plate, and one end of the outer frame is slidably connected to an inner slide.

[0008] As a further embodiment of this utility model: a clamping plate is fixedly connected to one side of the inner carriage, and the two clamping plates in the corresponding two fixing components are oriented opposite to each other.

[0009] As a further embodiment of this utility model: two sets of uprights are fixedly installed on the opposite side of the outer frame and the inner slide, and a return spring is sleeved on the outer wall of the two uprights in the same set.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The protective cover for the coupling of this vacuum pump unit, through the setting of a support mechanism, after the protective cover is installed, the protective plate protects the coupling. At the same time, if an external force is applied to the support rod in the support mechanism, the support rod will drive the support sliders at both ends to slide along the outer wall of the support column. During the sliding of the support sliders, the compression springs on the outer wall of the support column are squeezed. The compression springs are compressed and generate elastic force. This process not only buffers the external force and prevents the external force from acting directly on the protective plate, protecting the protective plate from being squeezed, but also maintains a safe distance between the protective plate and external objects by the distance between the support rod and the protective plate, ensuring the protective effect of the protective cover. 2. The protective cover for the coupling of this vacuum pump unit, through the setting of a fixing component, when the protective cover is installed, the fixing component in the corresponding two fixing plates is squeezed by the side of the vacuum pump opening, which pushes the inner slide in the fixing component, causing the inner slide to slide in the outer frame, thereby squeezing the return spring. After the return spring is compressed, it generates elastic force, which drives the clamping plate to clamp the connection end, thus ensuring the protective cover is firmly fixed on the vacuum pump unit. This not only improves the installation efficiency of the protective cover, but also ensures its stability and reliability during operation, effectively preventing the protective cover from falling off due to vibration or external force.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-4 As shown, this utility model provides a technical solution: a protective cover for a vacuum pump unit coupling, including a protective plate 1. A plurality of support mechanisms 2 are evenly and equidistantly arranged on the outer wall of the protective plate 1. Each support mechanism 2 includes a fixing frame 201, with two fixing frames 201 fixedly connected to the outer wall of the protective plate 1. A support column 202 is fixedly installed between the inner walls of the fixing frames 201. A support slider 203 is slidably connected to the outer wall of the support column 202. A compression spring 204 is sleeved on one side of the support slider 203 on the outer wall of the support column 202. A support rod 205 is fixedly connected to the opposite side of the two support sliders 203. Because of the support mechanism... 2. When an external force is applied to the support rod 205, the support slider 203 will slide along the support column 202, and the compression spring 204 will be compressed to generate elastic force, thereby buffering the external force and preventing the external force from acting directly on the protective plate 1. This protects the protective plate 1 from being squeezed while maintaining a safe distance between the protective plate 1 and external objects. The outer wall of the protective plate 1 has several through holes 3. The design of these through holes 3 helps to reduce the weight of the protective plate 1 without affecting its overall structural strength. At the same time, the operating status of the coupling inside the vacuum pump unit can be easily observed through the through holes 3. Two connecting plates 4 are fixedly connected to both ends of the protective plate 1. Two fixing plates 5 are fixedly connected to one side of the connecting plate 4. Two fixing components 6 are respectively provided on opposite sides of the two fixing plates 5. The two fixing components 6 are oriented opposite to each other. Because of the fixing components 6, when the inner slide 602 in the fixing component 6 is compressed during installation, the inner slide 602 will slide within the outer frame 601, compressing the return spring 605. The elastic force of the return spring 605 drives the clamping plate 603 to clamp the connecting end, thereby ensuring the protective cover is firmly fixed on the vacuum pump unit. The fixing component 6 includes an outer frame 601, which is fixedly connected to the fixing plate 5. One end of the outer frame 601 is slidably connected inside it. There is an inner slide 602, and a clamping plate 603 is fixedly connected to one side of the inner slide 602. The two clamping plates 603 in the corresponding two fixing components 6 are oriented opposite each other. Two sets of columns 604 are fixedly installed on the opposite side of the outer frame 601 and the inner slide 602 respectively. The outer wall of the two columns 604 in the same set is sleeved with a return spring 605. Because there are columns 604, the two corresponding columns 604 are inside the return spring 605. When the return spring 605 is squeezed and compressed, the columns 604 can support the return spring 605 inside the return spring 605, so as to prevent the return spring 605 from bending excessively and shifting.

[0014] The working principle of this utility model is as follows: When using the protective cover, the protective plate 1 is bent and both ends are snapped into the opening of the vacuum pump unit outside the coupling, so that it is fixed to the opening of the vacuum pump unit outside the coupling. When fixing the protective cover, the fixing components 6 in the corresponding two fixing plates 5 are squeezed by the side of the vacuum pump opening, which will push the inner slide 602 in the fixing component 6, so that the inner slide 602 slides in the outer frame 601. During the sliding process, the inner slide 602 squeezes the return spring 605. The return spring 605 is compressed and generates elastic force, which in turn drives the clamping plate 603 to clamp the connecting end. At the same time, the outer wall of the protective plate 1 The support mechanism 2 plays a protective role during the use of the protective cover. When a hand or other object accidentally touches the protective plate 1, the support rod 205 in the support mechanism 2 will first come into contact with it. The support rod 205 slides on the support column 202 through the support slider 203, and the compression spring 204 on the outer wall of the support column 202 will be compressed. The elastic force of the compression spring 204 can buffer the external force and prevent the external force from acting directly on the protective plate 1, thereby protecting the protective plate 1 from being squeezed and maintaining a safe distance between the protective plate 1 and external objects. In addition, the elastic action of the compression spring 204 also prevents the protective plate 1 from being deformed due to external force.
