Description

Technical Field

[0001] The utility model relates to the technical field of chassis, in particular to a hinge for a chassis. Background Art

[0002] A cabinet (chassis) is an independent or self-supporting casing used to house electrical or electronic equipment. The cabinet is generally equipped with doors, removable or non-removable side panels and back panels. The door is connected to the cabinet body with hinges, so the hinges bear the load-bearing capacity, rotation smoothness and damping of the door.

[0003] The Chinese utility model patent with publication number CN213898557U disclosed a bearing hinge on August 6, 2021, including a first hinge plate, a second hinge plate and a hinge shaft. The first hinge plate and the second hinge plate are rotatably connected by the hinge shaft. It is characterized in that a bearing is installed at the connection between the first hinge and the second hinge, and the hinge shaft is rotatably connected to the bearing. By installing a bearing on the hinge, the mechanical friction between the hinge shaft and the hinge plate can be converted into roller friction, thereby effectively extending the service life of the hinge. In addition, by setting the bearing, the lubrication of the hinge rotation can be effectively improved.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing hinges have hinge shafts exposed to the air. After long-term use, the lubricating oil evaporates or dissolves due to moisture, and a large amount of dust falls into the hinge, which increases the friction of rotation, thereby increasing the resistance during rotation and generating noise. Utility Model Content

[0005] The utility model aims to solve the technical problem that the hinge shaft of the existing hinge is exposed to the air, and after long-term use, the lubricating oil evaporates or dissolves with moisture, and a large amount of dust falls in, which increases the friction of rotation, thereby increasing the resistance during rotation and generating noise, and provides a hinge for a chassis.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model describes a hinge for a chassis, comprising a fixed page, a first hole and an avoidance groove; the fixed page is provided with a plurality of first holes and an avoidance groove; a movable page is limitedly inserted in the avoidance groove; a plurality of third holes are provided on the movable page; a through hole is provided on the movable page; the upper and lower ends of the through hole are symmetrically threadedly connected with limit rings; stepped shafts are symmetrically slidably inserted in two of the limit rings; an elastic member is fixed between the stepped shafts; a connecting hole is penetrated through the stepped shaft; an upper liquid storage tank and a lower liquid storage tank are provided on the fixed page corresponding to the connecting hole.

[0008] Furthermore, a second adsorption component is inserted into the lower liquid storage tank.

[0009] Furthermore, a first adsorption component is inserted into the upper liquid storage tank; and a sealing cover is threadedly connected to the upper opening of the upper liquid storage tank.

[0010] Furthermore, one end of the fixed page is fixedly connected to a right-angle page; a second hole is opened on the right-angle page.

[0011] Furthermore, a groove for switch rotation is provided on the upper surface of the sealing cover; and lubricating liquid is adsorbed in the first adsorbent and the second adsorbent.

[0013] 1. The utility model reduces the rolling friction resistance between the fixed leaf and the stepped shaft by applying lubricating liquid in the upper liquid storage tank and the lower liquid storage tank.

It does not come into contact with the outside air, does not absorb water, dust and oxidize and volatilize, and solves the problem that the rotating part of the existing hinge is easily oxidized, absorbed water and volatilized when exposed to the air;

[0014] 2. The utility model provides a groove for the switch rotation on the upper surface of the sealing cover, which makes it convenient to insert a tool into the groove to drive the sealing cover to rotate, thereby sealing the upper liquid storage tank, making it difficult for dust and air to enter and contact the lubricating liquid to cause oxidation, water absorption and volatilization, thereby extending the service life of the lubrication effect and reducing the rotation noise of the hinge, thereby solving the problem that the rotating part of the existing hinge is easily oxidized, absorbed and volatilized when exposed to the air.

[0021] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0024] See also Figure 1-4 As shown, a hinge for a chassis comprises a fixed page 1, a first hole 3 and an avoidance groove 5; the fixed page 1 is provided with a plurality of first holes 3 and an avoidance groove 5; a movable page 6 is inserted in a limited position in the avoidance groove 5; a plurality of third holes 7 are provided in the movable page 6; a through hole 9 is provided in the movable page 6; the upper and lower ends of the through hole 9 are symmetrically threadedly connected to a limit ring 8; stepped shafts 10 are symmetrically slidably inserted in two of the limit rings 8; an elastic member 11 is fixedly connected between the stepped shafts 10; a connecting hole 12 is provided through the stepped shaft 10; An upper liquid reservoir 13 and a lower liquid reservoir 17 are provided on the fixed page 1 corresponding to the connecting hole 12. When working, lubricating liquid is applied to the upper liquid reservoir 13 and the lower liquid reservoir 17, so that the rolling friction resistance between the fixed page 1 and the stepped shaft 10 is small. At the same time, due to the penetration of the connecting hole 12, the volatilized lubricating liquid is still in the fixed page 1, so that the service life is longer, and it does not come into contact with the outside air, and will not absorb water, absorb dust and oxidize and volatilize, thereby solving the problem that the rotating part of the existing hinge is easily oxidized, absorbed water and volatilized when exposed to the air.

[0025] The second adsorption member 16 is inserted into the lower liquid storage tank 17; when working, the lubricating liquid is adsorbed in the second adsorption member 16, so that the lubricating liquid can be in the lower liquid storage tank 17 for a long time to contact with the stepped shaft 10 for lubrication, thereby reducing the friction of rotation, generating less noise, and thus extending the service life.

[0026] A first adsorption member 15 is inserted into the upper liquid storage tank 13; the upper end opening of the upper liquid storage tank 13 is threadedly connected to a sealing cover 14; during operation, the lubricating liquid is adsorbed in the first adsorption member 15, so that the lubricating liquid can be located in the upper liquid storage tank 13 for a long time in contact with the stepped shaft 10 for lubrication, thereby reducing the friction of rotation, generating less noise, and thus extending the service life; the sealing cover 14 seals and blocks the upper liquid storage tank 13, making it difficult for dust and air to enter and contact the lubricating liquid to cause oxidation, water absorption and volatilization, thereby extending the service life of the lubrication effect and reducing the rotation noise of the hinge, thereby solving the problem that the rotating part of the existing hinge is easily oxidized, absorbed water and volatilized when exposed to the air.

[0027] One end of the fixed page 1 is fixedly connected to a right-angle page 2; a second hole 4 is opened on the right-angle page 2; during operation, the right-angle page 2 cooperates with the second hole 4 to diversify the installation position and angle, thereby adapting to the installation requirements of different chassis.

[0028] The upper surface of the sealing cover 14 is provided with a groove for switch rotation; the first adsorbent 15 and the second adsorbent 16 are adsorbed with lubricating liquid; when working, by providing the groove for switch rotation on the upper surface of the sealing cover 14, it is convenient to insert a tool into the groove to drive the rotation of the sealing cover 14, thereby sealing the upper liquid storage tank 13, making it difficult for dust and air to enter and contact with the lubricating liquid to cause oxidation, water absorption and volatilization, thereby extending the service life of the lubrication effect and reducing the rotation noise of the hinge, thereby solving the problem that the rotating part of the existing hinge is easily oxidized, absorbed and volatilized when exposed to the air.

[0029] By adopting the above scheme, when the utility model is in use, the rolling friction resistance between the fixed page 1 and the stepped shaft 10 is reduced by applying lubricating liquid in the upper liquid storage tank 13 and the lower liquid storage tank 17. At the same time, under the penetration of the connecting hole 12, the volatilized lubricating liquid is still in the fixed page 1, thereby extending the service life. It does not contact with the outside air, does not absorb water, absorb dust and oxidize and volatilize, and solves the problem that the rotating part of the existing hinge is easily oxidized, absorbs water and volatilizes when exposed to the air; by providing a groove for switch rotation on the upper surface of the sealing cover 14, it is convenient to insert a tool into the groove to drive the rotation of the sealing cover 14, thereby realizing the sealing of the upper liquid storage tank 13, making it difficult for dust and air to enter and contact with the lubricating liquid to cause oxidation, water absorption and volatilization, thereby extending the lubrication effect and service life, and the rotation noise of the hinge is low, and the problem that the rotating part of the existing hinge is easily oxidized, absorbs water and volatilizes when exposed to the air is solved.
