Description

Technical Field

[0001] This utility model relates to the field of tie rod technology, and in particular to tie rods for right-angle door elevators. Background Technology

[0002] The diagonal tie rod of a right-angle door elevator is a component of the elevator car frame. It is installed on the two side walls of the car and its main function is to enhance the rigidity of the car frame, adjust the levelness of the car bottom, and prevent the car bottom from tilting due to load eccentricity.

[0003] The existing patent publication number CN216444846U discloses an elevator car diagonal tie rod. This utility model, through the tie rod screw formed by the interconnection of a locking block and a locking seat, and the structural definition of the first round hole and the placement opening, allows the tie rod to be installed by first bolting the locking seat to the car, then snapping the tie rod with the locking block into the placement opening, and finally locking the locking block and the locking seat into each other by fixing the nut, thereby achieving the installation and positioning of the tie rod. With the above cooperation, this application does not require the tie rod screw to pass through the end during installation, and the fixing nut does not need to be screwed in again after the tie rod has passed through, thus effectively reducing the installation difficulty of the car diagonal tie rod.

[0004] However, in the process of using the right-angle door elevator tie rod disclosed in the above patent, the mounting plate and the elevator car frame column are fixedly connected by bolts. Since the bolt heads are directly exposed to the air, they are prone to corrosion and rust, which reduces the installation stability of the right-angle door elevator tie rod. Therefore, we propose a right-angle door elevator tie rod to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a right-angle door elevator tie rod, which can solve the problem that in the use of existing right-angle door elevator tie rods, the mounting plate and the elevator car frame column are fixedly connected by bolts. Since the head of the bolt is directly exposed to the air, it is easy to corrode and rust, thereby reducing the installation stability of the right-angle door elevator tie rod.

[0007] To solve the above technical problems, this utility model provides a right-angle door elevator diagonal tie rod, which adopts the following technical solution: it includes a tie rod, an installation plate is fixedly provided at the end of the tie rod, a threaded hole is fixedly opened inside the installation plate, and a protective component is provided on the side of the installation plate;

[0008] The protective component includes a sealing ring that is movably fitted to the side of the mounting plate. A protective box is fixedly provided on the side of the sealing ring away from the mounting plate. A fixing ring is fixedly provided on the outer ring of the protective box near the sealing ring. The central axis of the protective box and the threaded hole are on the same straight line.

[0009] A fixing component is provided between the fixing ring and the mounting plate.

[0010] Preferably, the fixing component includes support columns, which are fixedly disposed on the side of the mounting plate near the sealing ring. Four support columns are provided, and the four support columns are evenly distributed in a ring around the central axis of the threaded hole. A movable plate is slidably disposed on the support column. One end of the movable plate near the protective box is provided with an inclined surface. A connecting plate is fixedly disposed on the other end of the movable plate. A spring is fixedly connected between the connecting plate and the support column. The lower surface of the movable plate and the upper surface of the fixing ring are movably fitted together.

[0011] Preferably, the upper surface of the fixing ring is provided with a plurality of slots, which are evenly distributed in a ring around the central axis of the protective box. The lower surface of the movable plate is provided with a locking plate, which is engaged with the slots. The inside of the support column is provided with a through hole for the locking plate to pass through. The inner wall of the end of the protective box is provided with a limit block.

[0012] Preferably, a limiting plate is fixedly provided on the outer wall of the movable plate, and the limiting plate and the support column are movably fitted together on the side away from the protective box.

[0013] Preferably, the mounting plate is fixedly connected to the external column by bolts, the head of the bolt is located inside the protective box, and the head of the bolt has a limiting groove that matches the limiting block.

[0014] Preferably, a rubber plate is fixedly provided on the side of the mounting plate away from the sealing ring.

[0015] Preferably, a threaded rod is fixedly provided at the end of the pull rod away from the mounting plate, a fastening nut is threaded onto the threaded rod, and a sleeve rod is movably sleeved on the outside of the threaded rod, and the sleeve rod is fixedly connected to the outside of the car bottom.

[0016] In summary, this utility model has at least one of the following beneficial effects:

[0017] 1. After installing the bolts using the protective components, the protective box is placed over the bolt head and secured with the fixing components to fix the retaining ring. The protective box is then fixed to the mounting plate. The sealing ring prevents air from entering the cavity formed by the protective box and the mounting plate, thus preventing moisture corrosion of the bolts. This solves the problem that in existing right-angle door elevator tie rods, the mounting plate and the elevator car frame are fixedly connected by bolts. Since the bolt heads are directly exposed to the air, they are prone to corrosion and rust, which reduces the installation stability of the right-angle door elevator tie rod.

[0018] 2. After the bolts are installed and the fixed components are installed, as the protective box moves towards the mounting plate, the sealing ring presses against the inclined surface of the movable plate, forcing the movable plate to move away from the protective box. The spring is stretched until the sealing ring fits against the mounting plate and is compressed. At this point, the lower surface of the movable plate and the upper surface of the fixed ring are on the same plane. The spring recovers its elasticity, causing the movable plate to return to its original position and press down the upper surface of the fixed ring, thus quickly fixing the protective box and improving the efficiency of the protective box installation.

[0019] 3. By installing the slot, plate, and limit block, when installing the protective box, align the limit block with the limit groove on the head of the bolt. As the protective box moves towards the mounting plate, the limit block inserts into the limit groove. After the movable plate resets, it drives the plate to move and lock into the slot, preventing the fixing ring from rotating. This prevents the fixing ring, the protective box, and the limit block from rotating, thus preventing the bolt from loosening and further improving the stability of the bolt installation.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides an embodiment of a right-angle door elevator diagonal tie rod, including a tie rod 1. A mounting plate 5 is fixedly installed at the end of the tie rod 1. A threaded hole 6 is fixedly opened inside the mounting plate 5. The mounting plate 5 is fixedly connected to an external column by bolts. A threaded rod 2 is fixedly installed at the end of the tie rod 1 away from the mounting plate 5. A fastening nut 4 is threaded onto the threaded rod 2. A sleeve rod 3 is movably sleeved on the outside of the threaded rod 2. The sleeve rod 3 is fixedly connected to the external car bottom. (See reference) Figure 6 The columns and the car bottom together constitute the elevator car frame. Specifically, when installing the tie rod 1, the threaded rod 2 is inserted into the inside of the sleeve rod 3, and then the mounting plate 5 and the elevator car frame are fixedly connected with bolts. Finally, the fastening nut 4 is tightened to complete the installation of the tie rod 1. By setting four tie rods 1, the rigidity of the elevator car frame is enhanced, the levelness of the car bottom is adjusted, and the car bottom is prevented from tilting due to load eccentricity.

[0030] Considering that in the existing right-angle door elevator tie rods, the mounting plate 5 and the elevator car frame column are fixedly connected by bolts during use, and since the bolt heads are directly exposed to the air, they are prone to corrosion and rust, thereby reducing the installation stability of the right-angle door elevator tie rods, this utility model provides a protective component on the side of the mounting plate 5. By installing the protective component, the bolt heads are isolated from contact with the outside air, thereby slowing down the rusting speed of the bolts and ensuring the stability of their installation.

[0031] Furthermore, the protective component includes a sealing ring 9, which is movably fitted to the side of the mounting plate 5. A protective box 7 is fixedly installed on the side of the sealing ring 9 away from the mounting plate 5. A fixing ring 8 is fixedly installed on the outer ring of the protective box 7 near the end of the sealing ring 9. The central axis of the protective box 7 and the threaded hole 6 are on the same straight line. The head of the bolt is located inside the protective box 7. A fixing component is provided between the fixing ring 8 and the mounting plate 5.

[0032] After the bolts are installed, the protective box 7 is placed over the bolt head and the fixing ring 8 is secured by the fixing component. The protective box 7 is then fixed to the mounting plate 5. The sealing ring 9 prevents air from entering the cavity formed by the protective box 7 and the mounting plate 5, thus preventing moisture from corroding the bolts. This solves the problem that in the existing right-angle door elevator tie rods, the mounting plate 5 and the elevator car frame are fixedly connected by bolts. Since the bolt heads are directly exposed to the air, they are prone to corrosion and rust, which reduces the installation stability of the right-angle door elevator tie rod.

[0033] Furthermore, the fixing component includes support columns 10, which are fixedly installed on the side of the mounting plate 5 near the sealing ring 9. There are four support columns 10, which are evenly distributed in a ring around the central axis of the threaded hole 6. A movable plate 11 is slidably installed on the support column 10. One end of the movable plate 11 near the protective box 7 is provided with an inclined surface. A connecting plate 12 is fixedly installed on the other end of the movable plate 11. A spring 13 is fixedly connected between the connecting plate 12 and the support column 10. The lower surface of the movable plate 11 and the upper surface of the fixing ring 8 are movably fitted together.

[0034] Specifically, after the bolts are installed, as the protective box 7 moves towards the mounting plate 5, the sealing ring 9 presses against the inclined surface of the movable plate 11, forcing the movable plate 11 to move away from the protective box 7. The spring 13 is stretched until the sealing ring 9 fits against the mounting plate 5 and is compressed. At this point, the lower surface of the movable plate 11 and the upper surface of the fixed ring 8 are on the same plane. The spring 13 recovers its elasticity, causing the movable plate 11 to reset and press down the upper surface of the fixed ring 8, thereby quickly completing the fixing of the protective box 7 and improving the efficiency of the installation of the protective box 7.

[0035] To prevent the bolts from loosening, several slots 15 are fixedly provided on the upper surface of the fixing ring 8. The slots 15 are evenly distributed in a ring around the central axis of the protective box 7. A retaining plate 16 is fixedly provided on the lower surface of the movable plate 11. The retaining plate 16 and the slots 15 are interlocked. A through hole for the retaining plate 16 to pass through is fixedly provided inside the support column 10. A limiting block 17 is fixedly provided on the inner wall of the end of the protective box 7. A limiting groove that matches the limiting block 17 is provided on the head of the bolt.

[0036] Specifically, when installing the protective box 7, the limiting block 17 is aligned with the limiting groove on the head of the bolt. As the protective box 7 moves towards the mounting plate 5, the limiting block 17 is inserted into the limiting groove. After the movable plate 11 is reset, it drives the clamping plate 16 to move and clamp into the clamping groove 15, preventing the fixing ring 8 from rotating. This prevents the fixing ring 8, the protective box 7, and the limiting block 17 from rotating, thus preventing the bolt from loosening and further improving the stability of the bolt installation.

[0037] Furthermore, a limiting plate 14 is fixedly installed on the outer wall of the movable plate 11. The limiting plate 14 and the support column 10 are movably attached to the side away from the protective box 7. The position of the movable plate 11 is limited by the setting of the limiting plate 14.

[0038] Furthermore, a rubber plate 18 is fixedly installed on the side of the mounting plate 5 away from the sealing ring 9. The installation of the rubber plate 18 prevents moisture from coming into contact with the bolts through the connection between the mounting plate 5 and the column.

[0039] Working principle: When installing tie rod 1, insert threaded rod 2 into the inside of sleeve rod 3, then use bolts to fix mounting plate 5 and elevator car frame together. Finally, tighten fastening nut 4 to complete the installation of tie rod 1. Then, put protective box 7 on the outside of bolt head. During the process of protective box 7 moving towards mounting plate 5, sealing ring 9 presses against the inclined surface of movable plate 11, forcing movable plate 11 to move away from protective box 7. Spring 13 is stretched until sealing ring 9 fits against mounting plate 5 and is compressed. At this time, the lower surface of movable plate 11 and the upper surface of fixed ring 8 are on the same plane. Spring 13 restores its elasticity, driving movable plate 11 to return to its original position and pressing the upper surface of fixed ring 8. This allows for rapid fixation of the protective box 7. The sealing ring 9 prevents air from entering the cavity formed by the protective box 7 and the mounting plate 5, thus preventing moisture corrosion of the bolts and ensuring the stability of the connection between the mounting plate 5 and the elevator car frame. When installing the protective box 7, the limiting block 17 is aligned with the limiting groove on the head of the bolt. As the protective box 7 moves towards the mounting plate 5, the limiting block 17 inserts into the limiting groove. After the movable plate 11 resets, it drives the clamping plate 16 to move and clamp inside the clamping groove 15, preventing the fixing ring 8 from rotating. This prevents the fixing ring 8, the protective box 7, and the limiting block 17 from rotating, thus preventing the bolts from loosening and further improving the stability of the bolt installation.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
