Description

Technical Field

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

[0002] A hinge is a mechanical device used to connect two solid parts and allow them to rotate relative to each other. A hinge can be made of movable components or foldable materials. Hinges are mainly installed on doors and windows, while hinges are more often installed on cabinet furniture.

[0003] In the prior art, the force transmission auxiliary arm of the hinge and the connecting member are connected and matched through a fork and a sliding shaft. When the hinge is opened and closed, the fork and the sliding shaft slide and rotate at the same time. However, when the hinge is opened and closed, the friction resistance and friction wear between the sliding shaft and the fork are large, which makes the hinge opening and closing more laborious and reduces the service life of the hinge. Therefore, in order to solve the above technical problems, a hinge connection structure is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model proposes a hinge connection structure, which reduces the friction resistance and friction wear between the sliding shaft and the fork, saves effort in opening and closing the hinge, and increases the service life of the hinge.

[0005] A hinge connection structure, comprising:

[0006] A damper is rotatably mounted on one end of the hinge arm;

[0007] A force transmission auxiliary arm is rotatably mounted on the other end of the hinge arm, and a fork is provided at the end of the force transmission auxiliary arm close to the damper;

[0008] The linkage assembly includes a connecting block, a sliding shaft and a sleeve. The connecting block is rotatably mounted on the hinge arm and is located between the damper and the force transmission auxiliary arm. The telescopic end of the damper is hinged to the connecting block. The sliding shaft is rotatably connected to the connecting block. The sliding shaft is sleeved with the sleeve, and the sleeve is slidably arranged in the fork.

[0009] The beneficial effects of the above hinge connection structure are:

[0010] When the hinge opens and closes, causing the sliding shaft and the fork to slide and rotate at the same time, the sliding shaft can drive the sleeve to roll along the fork. At this time, there is rolling friction between the sleeve and the fork, thereby reducing the friction resistance and friction wear during the relative movement of the sliding shaft and the fork, thereby making the opening and closing of the hinge less laborious and increasing the service life of the hinge.

[0011] In one embodiment, the connection block includes two groups of connection plates arranged in parallel and spaced apart, the two groups of connection plates are connected by a fixed block, and the two ends of the sliding shaft are rotatably connected to the two groups of connection plates. By rotatably connecting the two ends of the sliding shaft, the firmness of the sliding shaft installed on the connection plate can be improved, and the stability of the sliding shaft and the fork joint can be improved.

[0012] In one embodiment, two groups of the connecting plates are provided with corresponding fixing holes, and the two ends of the sliding shaft are inserted into the two groups of the fixing holes. The sliding shaft and the connecting plate are matched with the shaft holes, which facilitates the installation of the sliding shaft on the connecting plate or removal from the connecting plate, thereby facilitating the replacement of the shaft sleeve.

[0013] In one embodiment, the sleeve is located between the two groups of connecting plates, and both end surfaces of the sleeve are in contact with the opposite surfaces of the two groups of connecting plates. When the sleeve rotates, the sleeve can be prevented from sliding along the axial direction of the sliding shaft, thereby reducing the friction resistance and friction wear between the sleeve and the sliding shaft, and improving the service life of the sleeve.

[0014] In one embodiment, the fork is a waist-shaped hole with one end open, and the diameter of the sleeve is equal to the distance between the two parallel surfaces of the fork. When the force transmission auxiliary arm rotates, the force transmission auxiliary arm can cooperate with the sleeve through the two parallel surfaces on the fork to drive the connecting plate to rotate synchronously, thereby making the damper telescopic and improving the stability of the device linkage.

[0015] In one embodiment, the force transmission auxiliary arm comprises a plurality of groups of steel sheets, and the plurality of groups of steel sheets are stacked to improve the strength of the force transmission auxiliary arm, thereby increasing the service life of the force transmission auxiliary arm.

[0025] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0026] See also Figures 1 to 4 In one embodiment, a hinge connection structure includes a damper 10, a force transmission auxiliary arm 20 and a linkage assembly 30.

[0027] The damper 10 is rotatably mounted on one end of the hinge arm. The force transmission auxiliary arm 20 is rotatably mounted on the other end of the hinge arm, and a fork 201 is provided at the end of the force transmission auxiliary arm 20 close to the damper 10. Furthermore, the force transmission auxiliary arm 20 includes multiple groups of steel sheets, which are stacked. The strength of the force transmission auxiliary arm 20 can be improved, thereby improving the service life of the force transmission auxiliary arm 20.

[0028] The linkage assembly 30 includes a connection block, a sliding shaft 303 and a shaft sleeve 302. The connection block is rotatably mounted on the hinge arm and is located between the damper 10 and the force transmission auxiliary arm 20. The telescopic end of the damper 10 is hinged to the connection block. The sliding shaft 303 is rotatably connected to the connection block. The sliding shaft 303 is sleeved with a shaft sleeve 302. The shaft sleeve 302 is slidably arranged in the fork 201.

[0029] In the above embodiment, when the hinge opens and closes so that the sliding shaft 303 and the fork 201 slide and rotate at the same time, the sliding shaft 303 can drive the sleeve 302 to roll along the fork 201. At this time, the sleeve 302 and the fork 201 are in rolling friction, thereby reducing the friction resistance and friction wear when the sliding shaft 303 and the fork 201 move relative to each other, thereby making the opening and closing of the hinge less laborious and increasing the service life of the hinge.

[0030] See also Figure 1 , Figure 2 In one embodiment, the connection block includes two sets of connection plates 301 arranged in parallel and spaced apart, the two sets of connection plates 301 are connected by a fixed block 305, and both ends of the sliding shaft 303 are rotatably connected to the two sets of connection plates 301.

[0031] Furthermore, the two groups of connecting plates 301 are provided with corresponding fixing holes 304 , and both ends of the sliding shaft 303 are inserted into the two groups of fixing holes 304 .

[0032] In the above embodiment, both ends of the sliding shaft 303 are inserted into two groups of fixing holes 304. By limiting the two ends of the sliding shaft 303, the firmness of the sliding shaft 303 installed on the connecting plate 301 can be improved, and the stability of the sliding shaft 303 and the fork 201 can be improved, thereby avoiding the sliding shaft 303 from tilting due to uneven force. At the same time, the sliding shaft 303 and the connecting plate 301 are matched with shaft holes, which makes it easy for the sliding shaft 303 to be installed on the connecting plate 301 or removed from the connecting plate 301, thereby facilitating the replacement of the shaft sleeve 302.

[0033] See also Figure 2 In one embodiment, the sleeve 302 is located between the two sets of connecting plates 301 , and both end surfaces of the sleeve 302 are in contact with the opposite surfaces of the two sets of connecting plates 301 .

[0034] In the above embodiment, the two end faces of the sleeve 302 are in contact with the opposing faces of the two sets of connecting plates 301. When the sleeve 302 rotates, the sleeve 302 can be prevented from sliding axially along the sliding shaft 303, thereby reducing the friction resistance and friction wear between the sleeve 302 and the sliding shaft 303 and improving the service life of the sleeve 302.

[0035] See also Figure 4 In one embodiment, the fork opening 201 is a waist-shaped hole with one end open, and the diameter of the sleeve 302 is equal to the distance between the two parallel surfaces of the fork opening 201.

[0036] In the above embodiment, when the force transmission auxiliary arm 20 rotates, the force transmission auxiliary arm 20 can cooperate with the shaft sleeve 302 through the two parallel surfaces on the fork 201 to drive the connecting plate 301 to rotate synchronously, thereby making the damper 10 telescopic and improving the stability of the linkage of the device.

[0037] The specific implementation of the above hinge connection structure is:

[0038] When the hinge opens and closes so that the sliding shaft 303 and the fork 201 slide and rotate at the same time, the sliding shaft 303 can drive the sleeve 302 to roll along the fork 201. At this time, the sleeve 302 and the fork 201 are in rolling friction, thereby reducing the friction resistance and friction wear when the sliding shaft 303 and the fork 201 move relative to each other, thereby making the hinge opening and closing effortless and increasing the service life of the hinge. The two end faces of the sleeve 302 are in contact with the opposing faces of the two sets of connecting plates 301. When the sleeve 302 rotates, the sleeve 302 can be prevented from sliding axially along the sliding shaft 303, thereby reducing the friction resistance and friction wear between the sleeve 302 and the sliding shaft 303 and increasing the service life of the sleeve 302.

[0039] When the shaft sleeve 302 needs to be replaced, the two ends of the sliding shaft 303 can be removed from the fixing hole 304. At this time, the sliding shaft 303 can cancel the fixation of the shaft sleeve 302, and the shaft sleeve 302 can be taken out from the fork 201. Then the new shaft sleeve 302 is placed in the fork 201, and the two ends of the shaft sleeve 302 are aligned with the fixing hole 304. Finally, the sliding shaft 303 is inserted into the shaft sleeve 302 and the two ends of the sliding shaft 303 are inserted into the fixing hole 304 to fix the shaft sleeve 302, which makes it convenient to replace the shaft sleeve 302.
