Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, and in particular to a curtain hook that is easy to lift and lower. Background Technology

[0002] Curtain hooks for general items, such as Figure 1 As shown, curtains directly connected to the curtain rod rings (holes) will shift between the curtain and the hooks after being hung for a long time. Furthermore, when operators pull the curtains, misalignment between the curtain and the hooks can easily occur, further reducing the effectiveness of the curtain hooks. In addition, some areas have specific requirements for curtain installation, especially public places and hotel projects, where the installation quality requires the curtains to be 2-3mm off the ground to ensure a light-blocking effect. However, the height of curtain rods varies from hotel to hotel or public place to public place, while the standard hook length is fixed. Therefore, to meet the curtain's ground clearance requirement, either the hooks must be removed from the curtain and reattached to the appropriate position, or the hooks must be replaced with hooks of suitable length. However, both methods are time-consuming, labor-intensive, difficult to operate, and costly. Utility Model Content

[0003] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0004] A curtain hook that is easy to raise and lower includes a hook body and a tooth assembly.

[0024] refer to Figures 2-4 As shown, one embodiment of this utility model is as follows:

[0025] A curtain hook that is easy to raise and lower includes a hook body 1 and a locking tooth assembly 2. The hook body 1 has a closed U-shaped structure, with the inner walls at both ends bent and fitted together. A plurality of first locking teeth 3 are provided on one side of the outer wall of the hook body 1. The first locking teeth 3 have a conical structure and are evenly arranged from top to bottom along the length of one side of the outer wall of the hook body 1, with the tips of the first locking teeth 3 facing upwards. The locking tooth assembly 2 is slidably adapted to the side of the hook body 1 with the first locking teeth 3, and the locking tooth assembly 2 engages with the first locking teeth 3.

[0026] In this invention, the hook body 1 is used to connect curtains. Specifically, the hook body 1 is made of materials such as plastic or stainless steel. When the curtain needs to be connected to the hook body 1, due to the elasticity of materials such as plastic and stainless steel, the two sides of the closed opening of the hook body 1 can be slightly pried outward to leave a certain gap. At this time, one end of the curtain can be moved into the U-shaped concave surface of the hook body 1 through this gap. The two sides of the hook body 1 are then released, and under the action of the elastic force, they move inward to fit together and clamp the curtain. The locking tooth assembly 2 is used to connect the hook body 1 and the curtain to the curtain rod, and the locking tooth assembly 2 is slidably adapted to the hook body 1. When the locking tooth assembly 2 is connected to the curtain rod, the height of the hook body 1 can be easily and quickly adjusted by sliding it, thereby adjusting the height of the curtain. Compared with the prior art, there is no need to remove the hook from the curtain or replace it with a new hook, making the operation more convenient and faster, and reducing the cost of use.

[0027] Specifically, the tooth assembly 2 includes a sliding part 201 and a hook part 202. The sliding part 201 is slidably connected to the side of the hook body 1 where the first tooth 3 is provided, and the hook part 202 is fixedly connected to the sliding part 201, such as... Figure 4 As shown, the top cross-section of the hook body 1 with the first locking tooth 3 is T-shaped. The first locking tooth 3 is symmetrically arranged with the center line of the T-shape as the axis of symmetry. The sliding part 201 has a T-shaped hole 203 that is adapted to the hook body 1. The T-shaped hole 203 adapts to the T-shaped side of the hook body 1, which can restrict the degree of freedom of the sliding part 201 in the left-right and front-back directions, ensuring that the sliding part 201 can only slide up and down. A second locking tooth 204 is provided on one side of the T-shaped hole 203. The second locking tooth 204 is adapted to the first locking tooth 3, that is, the second locking tooth 204 is a conical structure with the cone tip facing downward. The inclined side of the second locking tooth 204 is in contact with the inclined side of the first locking tooth 3. Through the mutual engagement of the first locking tooth 3 and the second locking tooth 204, the sliding part 201 can only slide downward along the hook body 1 and cannot slide upward. That is to say, the hook body 1 can only slide upward relative to the sliding part 201 and cannot slide downward. When the hook body 1 is connected to a curtain, the curtain will exert a downward pulling force on the hook body 1. At this time, the hook body 1 is kept stable under the action of the first locking tooth 3 and the second locking tooth 204, and is prevented from being pulled downward.

[0028] The hook part 202 has a U-shaped structure, and the direction of the U-shaped concave surface of the hook part 202 is opposite to the direction of the U-shaped concave surface of the hook body 1. It is dynamically connected to the pull ring or hole on the curtain rod through the hook part 202.

[0029] The angle A between the bottom edge and the inclined edge of the first locking tooth 3 is 90°. When the second locking tooth 204 engages with the first locking tooth 3, the 90° setting allows the bottom edge of the second locking tooth 204 and the bottom edge of the first locking tooth 3 to be subjected to a vertical force, preventing the second locking tooth 204 from sliding upward.

[0030] In this invention, the curtain is prone to shifting due to the clamping of the two sides of the hook body 1. Therefore, in order to enhance the stability of the curtain, the inner walls of the two sides of the hook body 1 are provided with staggered fixing teeth 4. When the curtain is connected to the hook body 1, the staggered fixing teeth 4 can contact the two sides of the curtain to clamp the curtain, prevent the curtain from being pulled and prevent the curtain from shifting.

[0031] Specifically, the length of the first locking tooth 3 and the second locking tooth 204 is 0.2mm, which means that each time the locking tooth assembly 2 is adjusted, it slides downward a distance of 0.2mm, making it easy for the operator to adjust the curtain to a position 2-3mm off the ground.

[0032] The first locking tooth 3 and the second locking tooth 204 are made of the same material as the hook body 1, possessing a certain degree of resilience. When the locking tooth assembly 2 is moved downwards, the first locking tooth 3 and the second locking tooth 204 press against each other, facilitating movement. After movement, they return to their original shape under the action of the rebound force, preventing upward movement. It should be noted that during actual adjustment, the locking tooth assembly 2 may move downwards too far, resulting in the curtain's distance from the ground not meeting the requirements. In this case, simply continue moving the locking tooth assembly 2 downwards until it moves out of the hook body 1 from below, and then slide the locking tooth assembly 2 back into the hook body 1 from above.

[0033] The following points need to be explained:

[0034] (1) Unless otherwise defined, the same reference numerals in the embodiments and drawings of this disclosure have the same meaning.

[0035] (2) The accompanying drawings of the embodiments of this disclosure only involve the structures involved in the embodiments of this disclosure. Other structures can be referred to the general design.

[0036] (3) For clarity, components or areas are enlarged in the drawings used to describe embodiments of the present disclosure. It will be understood that when an element is referred to as being “above” or “below” another element, the element may be “directly” located “above” or “below” the other element, or there may be an intermediate element.

[0037] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
