Description

Technical Field

[0001] The utility model relates to the technical field of door closers, and particularly relates to a stable mounting member for a door closer. Background Technique

[0002] A door closer is a hydraulic device similar to a spring on the door head. After the door is opened, it can be compressed and then released to automatically close the door, playing a role like a spring door, which can ensure that after the door is opened, it can be accurately and timely closed to the initial position. When installing a door closer, one end of the connecting rod of the door closer is generally connected to the door frame through a mounting member installed on the door frame.

[0003] In the existing mounting member, the connection part with the connecting rod is mostly exposed outside. During long-term use, dust and moisture are likely to invade the connection part. Excessive dust and impurities accumulating at the connection part will affect the rotation of the connecting rod, thereby affecting the use effect of the door closer. At the same time, it will accelerate the aging of the connection part, thus reducing the service life of the door closer. Therefore, a stable mounting member for a door closer is proposed to solve the problems mentioned above. Summary of the Utility Model

[0023] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0024] Referring to Figures 1 - 3 As shown in the figure, a stable mounting member for a door closer includes a mounting base 1. The lower part of the front end of the mounting base 1 is fixedly connected with a lower fixing base 2. The rear part of the upper end of the lower fixing base 2 is fixedly connected with a first limiting block 3. The front side of the first limiting block 3 on the upper end of the lower fixing base 2 is fixedly connected with a second limiting block 4. An arc-shaped rotating groove 5 is formed between the first limiting block 3 and the second limiting block 4. A dust-proof block 6 is rotatably connected inside the rotating groove 5. The upper end of the lower fixing base 2 is movably connected with a connecting rod 7. Both ends of the dust-proof block 6 are respectively abutted against the left and right sides of the connecting rod 7.

[0025] Furthermore, both ends of the dust-proof block 6 being respectively abutted against the left and right sides of the connecting rod 7 can seal the connection between the connecting rod 7 and the mounting member. And when the connecting rod 7 rotates, it will push the dust-proof block 6 to move in the rotating groove 5, which can ensure that the dust-proof block 6 is always in close contact with the surface of the connecting rod 7, thereby preventing external dust and moisture from entering the connection, avoiding excessive dust and impurities from accumulating at the connection and affecting the rotation of the connecting rod 7, and at the same time slowing down the aging of the connection, improving the service life of the door closer.

[0026] Referring to Figures 1 - 4 As shown in the figure, the upper end of the first limiting block 3 is movably connected with an upper fixing base 8. A first fixing hole 10 is penetrated and opened in the middle of the upper end of the lower fixing base 2. A connecting hole 11 is penetrated and opened at the corresponding position of the upper end of the connecting rod 7 with respect to the first fixing hole 10. A second fixing hole 17 is penetrated and opened at the corresponding position of the upper end of the upper fixing base 8 with respect to the connecting hole 11.

[0027] Furthermore, two symmetrically distributed positioning grooves 13 are opened at the upper end of the first limiting block 3. A first threaded hole 12 is opened at the rear end of the upper end of the first limiting block 3 with respect to the positioning groove 13.

[0028] Further, at the corresponding position between the lower end of the upper fixing seat 8 and the positioning groove 13, a docking block 14 with the same size as the positioning groove 13 is fixedly connected. The docking block 14 is inserted into the positioning groove 13. At the corresponding position between the lower end of the upper fixing seat 8 and the first threaded hole 12, a second threaded hole 15 is penetrated. A fastening bolt 18 is threadedly connected inside the second threaded hole 15 and the first threaded hole 12.

[0029] Further, the positioning groove 13 and the docking block 14 can play a positioning role in the installation of the upper fixing seat 8, and at the same time can prevent the upper fixing seat 8 from sliding during the installation process, facilitating the rapid installation of the upper fixing seat 8.

[0030] Further, an upper limiting groove 16 is provided at the corresponding position between the lower end of the upper fixing seat 8 and the dust-proof block 6, and a lower limiting groove 9 is provided at the corresponding position between the upper end of the lower fixing seat 2 and the dust-proof block 6. The upper and lower ends of the dust-proof block 6 are respectively slidably connected inside the upper limiting groove 16 and the lower limiting groove 9.

[0031] Further, the upper limiting groove 16 and the lower limiting groove 9 can play a limiting role on the dust-proof block 6 to prevent it from shifting.

[0032] Refer to Figure 1 and Figure 6 As shown, a fixing pin 21 is rotatably connected inside the first fixing hole 10, the connecting hole 11 and the second fixing hole 17. A threaded portion 22 is provided on the upper part of the outer surface of the fixing pin 21. A fastener 23 is threadedly connected to the upper end of the fixing pin 21 through the threaded portion 22.

[0033] Further, a plurality of anti-slip grooves 24 are provided on the outer surface of the fastener 23.

[0034] Further, the provision of the anti-slip grooves 24 can increase the friction force for the tool to grip the fastener 23, facilitating the installation of the fastener 23.

[0035] Further, mounting holes 19 are penetrated through the four corners at the front end of the mounting base 1. Screws 20 are threadedly connected inside the mounting holes 19. By marking drill holes on the door frame, then aligning the mounting holes 19 with the drill holes and installing the screws 20 into the mounting holes 19 and the drill holes, the mounting part can be installed on the door frame.

[0036] Working principle: When in use, select a suitable position on the door frame to draw marks for drilling. Then align the four mounting holes 19 on the mounting base 1 with the drilled holes, and install the screws 20 inside the mounting holes 19 and the drilled holes to fix the mounting base 1. Then place the dust-proof block 6 in the lower limit groove 9 and the rotating groove 5, and install the connecting rod 7 at the upper end of the lower fixing seat 2. The two ends of the dust-proof block 6 are respectively abutted against the left and right sides of the connecting rod 7. Then align the docking block 14 of the upper fixing seat 8 with the positioning groove 13 on the first limiting block 3 and insert the docking block 14 into the positioning groove 13. Then install the fastening bolt 18 inside the second threaded hole 15 and the first threaded hole 12 to fix the upper fixing seat 8. After that, sequentially pass the fixing pin 21 through the first fixing hole 10, the connecting hole 11 and the second fixing hole 17, and install the fastener 23 at the end of the fixing pin 21 to install the connecting rod 7 on the mounting member. The dust-proof block 6 can seal the connection between the connecting rod 7 and the mounting member, prevent external dust and moisture from entering the connection, avoid excessive dust and impurities from accumulating at the connection and affecting the rotation of the connecting rod 7, and at the same time can slow down the aging of the connection, improving the service life of the door closer.
