Description

Technical Field

[0001] The utility model relates to the technical field of toilet bathroom, in particular to a damper with a large adjustable range. Background Technique

[0002] Toilet seats are commonly used in people's daily lives. Generally, the cover plate of the toilet seat is directly connected to the toilet seat by a pin shaft or a buffer damping structure is adopted. When using the pin shaft structure, a relatively large impact sound will be generated when the cover plate is put down. Although the buffer damping structure can achieve the buffering effect, there are also some deficiencies in actual applications. For example, some users are used to using greater force during the process of closing the cover. Most of the conventional toilet cover buffer dampers adopt a torsion spring structure. The damping value of this torsion spring is fixed. Although the resistance can adapt to most users, it is difficult to effectively cope with the torsion impact caused by this large-force rotary push, and still a relatively large impact sound will be caused. In the long run, the connection structure will also be damaged, which cannot meet the needs of some customers. Therefore, there is a need for a buffer damper for toilet covers with a sufficient buffer resistance stroke and adjustable. Summary of the Utility Model

Specific embodiments

[0018] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0019] Secondly, the present utility model will be described in detail with reference to the schematic diagrams. When describing the embodiments of the present utility model in detail, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally in a non-general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present utility model herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0020] In order to make the purpose, technical solution and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

[0021] Figures 1-3 Shown is a schematic diagram of the entire structure of a damper with a large adjustable range of the present utility model. Please refer to Figures 1-3 , a damper with a large adjustable range of the present embodiment includes a base 100. The upper part and the inner side of the base 100 are provided with chutes 110 arranged along its length direction. A hinge seat 200 is provided on one side of the front end of the top of the base 100, and the upper front end of the hinge seat 200 is fixedly connected to the root of the toilet lid. A first slider 300 located at the front end and a second slider 400 located at the rear end are slidably arranged inside the chute 110. A spring 500 is linearly connected between the first slider 300 and the second slider 400. A connecting rod 600 is also hinged on one side of the upper front end of the hinge seat 200, and the connecting rod 600 is at an inclined angle and its lower end is hinged to the first slider 300. Among them, the second slider 400 can move relatively towards the first slider 300 and is fixed inside the chute 110 through a locking member. When the toilet lid is turned downwards, it can drive the connecting rod 600 to push the first slider 300 to move towards the second slider 400.

[0022] The hinge seat 200 includes a fixed plate 210 fixed to the upper end of the base 100, an L-shaped movable plate 220 with one end close to the upper end of the fixed plate 210 and rotatably connected by a rotating shaft 1 230, and the root of the toilet cover is fixed to the outer end of the L-shaped movable plate 220. It can be understood that the root of the toilet cover is elevated and installed by the hinge seat 200, so that the connecting rod 600 on one side has a sufficient working angle when the toilet cover is closed and lifted. The upper end of the slider 1 300 has a fixing ear 310, and the upper and lower ends of the connecting rod 600 are respectively rotatably connected with the L-shaped movable plate 220 and the fixing ear 310 through the rotating shaft 2 610. The lower end connection of the connecting rod 600 is elevated by the fixing ear 310, which can prevent the connecting rod 600 from being blocked by the base 100 when rotating downward. The slider 2 400 is provided with a threaded sleeve 420 which passes through the slider 2 400 from top to bottom in the center, and a locking bolt 410 is screwed into the inner side of the threaded sleeve 420; a plurality of equally spaced positioning screw holes 120 are provided at the inner bottom of the slide groove 110 and along its length direction, and the positioning screw holes 120 and the threaded sleeve 420 are on the same central axis. After the slider 2 400 is adjusted to a suitable position, the locking bolt 410 can be screwed into the threaded sleeve 420 and the corresponding positioning screw hole 120 to lock the slider 2 400 firmly; specifically, in the present embodiment, when the damping value needs to be increased, the slider 2 400 can be moved along the inner side of the slide groove 110 toward the slider 1 30 0 direction, and after adjusting to a suitable position, the slider 400 is locked by the locking bolt 410. The greater the movement stroke of the slider 400, the greater the extrusion force of the spring 500. At the same time, the toilet cover is subjected to greater reverse push resistance from the connecting rod 600, the slider 300 and the spring 500 when the toilet cover is closed and flipped. Conversely, the more the slider 400 is adjusted, the smaller the closing resistance of the toilet cover. In summary, the damper device has a large damping adjustment range, which can be freely adjusted according to the actual needs of the user, effectively preventing and reducing the torque impact and impact noise caused by strong rotation and pushing, protecting the connection structure, and meeting the customer's usage needs as much as possible.

[0023] Furthermore, the base 100 is provided with a plurality of mounting holes, and anchor bolts 700 connected to the toilet are penetrated inside the mounting holes. It can be understood that the base 100 of the damper can be conveniently fixed and installed through the mounting holes and the anchor bolts 700. Of course, other suitable connection methods can also be used for fixed installation during actual assembly, and this is not limited.

[0024] Furthermore, the main structure of the damper is made of stainless steel, which makes the damper rust-proof, durable and stable. In addition, in actual application, a protective cover can be set above the damper, that is, on the upper part of the base 100, which not only has an aesthetic effect, but also serves as an external protection.

[0025] In summary, for the damper with a large adjustable range in this embodiment, when it is necessary to increase the damping value, the second slider 400 can be moved along the inner side of the sliding groove 110 and towards the first slider 300. After adjusting to a suitable position, the second slider 400 is locked by the locking bolt 410. The greater the moving stroke of the second slider 400, the greater the extrusion force on the spring 500. At the same time, when the toilet lid is flipped during closing, the reverse pushing resistance received by the connecting rod 600, the first slider 300 and the spring 500 is greater. On the contrary, adjusting the second slider 400 reduces the closing resistance of the toilet lid. In summary, this damper device has a large damping adjustment range and can be freely adjusted according to the actual needs of users, effectively preventing and reducing the torque impact and impact noise caused by vigorously rotating and pushing.

[0026] Although the present invention has been described above with reference to the embodiments, various improvements can be made to it and components therein can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention can be combined with each other in any way. The reason for not exhaustively describing the situations of these combinations in this specification is only to save space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
