Abstract
Description
Technical Field
[0001] The utility model relates to the field of mechanical connection devices, specifically to an adjustable stop structure device that can be fixed at any position in this field, which is used for various chassis or other equipment placed on racks. Background Technique
[0002] The chassis is an important structure for installing and protecting electronic components, devices, mechanical parts and components of electronic equipment. Most chassis are fixed on the cabinet through rails such as fixed pallets, two-section rails, and three-section rails.
[0003] At present, the vast majority of electronic equipment adopts a vertical cabinet structure. Based on the complexity of each device, the usage scenario, as well as the number of chassis, U number, and weight in the device, each chassis in the device needs to be centrally installed on the cabinet according to electrical and ergonomic requirements. For the convenience of operation and maintenance, during debugging and maintenance, the vast majority of chassis need to be pulled out through rails. Therefore, the precise position of the rail on the rack determines the precise position of the chassis.
[0004] There are also various ways to fix the rails on the cabinet. Most of them are screwed on the rack. To ensure the installation and the gap between adjacent chassis, it is necessary to adjust the rails connecting the chassis up and down to ensure that the gap between the chassis is between 0.8 and 1.2 mm, and at the same time, ensure that the chassis panel can coincide with the mounting holes on the rack.
[0005] At present, there are two main ways to fix the chassis rails on most cabinets. One is Figure 1 as shown in the figure, by designing vertical long holes or inclined long holes on the rail columns, and the other is Figure 2 as shown in the figure, by installing clip nuts on the rail columns.
[0006] The first method can achieve the purpose of adjusting the height of the rail up and down and then adjusting the gap between adjacent chassis. However, it has the following three disadvantages: First, when adjusting the rail by this method, it is necessary to determine the position of the rail through screws, and the positioning accuracy is poor; Second, after adjusting the gap, it is necessary to match and drill positioning holes on the rail and the cabinet to ensure that the position of the rail does not change during use; Third, when adjusting the gap of a chassis weighing more than 10 kg, the process is complex and the adjustment is difficult.
[0007] The second method is often used in the network cabinets of electronic equipment, and the installed chassis are all network chassis. The distance between each chassis is large. This method has the following disadvantages: First, such cabinets are all indoor cabinets, and the accuracy of the position of the rails installed on the cabinet is not high; Second, the weight of the chassis placed on the rack is light, and it can be fixed only by screws; Third, the interval between adjacent chassis is very large, and there is no 0.8 - 1.2 mm gap between standard adjacent chassis. Content of the Utility Model
[0008] The technical problem to be solved by the present utility model is to provide an adjustable stop structure device that can be fixed at any position. This device can be rigidly connected to various guide rails, and has the advantages of simple structure, reliable fixation at any position, convenient and fast up and down adjustment, etc. It can be fully used to adjust the position gap of the chassis in actual indoor and vehicle-mounted cabinets.
[0009] To solve the above technical problems, the present utility model adopts the following technical solutions:
[0010] An adjustable stop structure device that can be fixed at any position, which is improved in that: it includes a spacer block and a stud fixedly installed on the spacer block. A fastener is screwed on the stud and a stop block is sleeved. The stop block can move between the spacer block and the fastener along the stud. A groove is provided on the surface of the stop block opposite to the spacer block, and a special-shaped protrusion is provided in the groove.
[0011] Further, the spacer block is fixedly connected to the guide rail.
[0012] Further, the fastener is a nut.
[0013] Further, the stop block is made of cast carbon steel, cast by a steel mold, and immersed in anti-rust oil.
[0014] Further, the spacer block and the stud are made of steel and are subjected to surface galvanizing treatment after processing.
[0015] The beneficial effects of the present utility model are:
[0016] The device disclosed by the present utility model has a wide range of applications and can be popularized and applied to various occasions for up and down position adjustment. The adjustment process is simple. Only need to loosen the fastener, and then the stop block can slide along the auxiliary device to realize up and down movement. After tightening the fastener, the stop block is embedded in the auxiliary device to achieve final fixation. The adjustment accuracy is high, and the up and down adjustment accuracy can be controlled within 0.5 mm.
[0017] A groove is provided on the stop block, and a special-shaped protrusion structure is provided in the groove. This special-shaped protrusion structure can be paired and fixed with an auxiliary device (such as a cabinet, a rack, etc.) with a slot structure. The fastener can completely press the stop block and the auxiliary device (such as a cabinet, a rack, etc.) without falling off.
[0018] The stop block is cast by a steel precision mold, and the materials are all ordinary cast carbon steel. It has a high strength grade. The internal special-shaped protrusion structure is not easy to wear during adjustment and can be reused, improving the service life of the device. After casting, it is immersed in anti-rust oil, and the surface treatment process is simple and practical. Description of the Drawings
