Continuing to refer to FIG. 1, the slide rail includes a first slide rail 11 and a second slide rail 12, and the slider includes a first slide 21 and a second slide 22. Wherein, the first slider 21 is sleeved on the first slide rail 11 and can slide relative to the first slide rail 11, and the second slide block 22 is sleeved on the second slide rail 12 and can interact with the second slide rail 12 Relative sliding occurred.

In order to realize the relative sliding of the sliding rail and the sliding block, a groove penetrating up and down can be provided on the sliding block, the sliding rail is inserted in the groove, and the sliding rail can slide up and down along the groove. Specifically referring to FIG. 2, the first sliding block 21 is provided with a first groove 211 penetrating up and down, and the second sliding block is provided with a second groove 221 penetrating up and down. Wherein, the shapes of the first groove 211 and the second groove 221 match the sliding rail. If the groove is a dovetail groove, the cross-sectional shape of the slide rail is a dovetail shape. Another example is that the groove is a circular groove, and the cross-sectional shape of the slide rail is circular.

It is worth mentioning that the groove on the sliding block and the sliding rail may have a variety of cross-sectional shapes that cooperate with each other.

Further, in order to prevent the slider from detaching from the sliding rail (or the sliding rail from the groove), a limit protrusion is provided at both ends of the sliding rail, and the limit protrusion is higher than the gap between the sliding rail and the groove. Preferably, the limiting protrusions may be limiting screws installed at both ends of the sliding rail.

Next, the matching relationship between the slider and the sliding clip 3 will be described. Please refer to FIG. 3, which is a cross-sectional view of FIG. 2 at the opening groove in the slider. In order to realize the cooperation between the sliding block and the movable clip 3, a first opening groove 212 is opened on one end surface of the first sliding block 21. It is inclined toward the inside thereof. Specifically, the inclination angle of the first opening groove 212 with respect to the vertical plane is −α. Similarly, a second opening groove 222 is opened on one end surface of the second slider 22, and the first opening groove 222 is a chute, which is inclined from the end surface of the second slider 22 to the inside, specifically, as shown in FIG. 3 As shown, the inclination angle of the second opening groove 222 with respect to the vertical direction is α.

Preferably, in order to prevent the movable clip from slipping out of the opening groove, the first opening groove 212 and the second opening The bottom end of the groove 222 is sealed.

Further, since the first opening groove 212 and the second opening groove 222 are symmetrically arranged along the vertical direction, there is a maximum distance and a minimum distance between the bottom slopes of the first opening groove 212 and the second opening groove 222. The distance, wherein the maximum distance is located at the lower ends of the first opening groove 212 and the second opening groove 222, and the minimum distance is located at the upper ends of the first opening groove 212 and the second opening groove 222.

When the movable clip 3 slides toward the minimum distance, since the distance between the bottom slopes of the first opening groove 212 and the second opening groove 222 is gradually reduced, the slider and the slide rail When the minimum distance is reached, the sliding block and the slide rail are in a locked state; when the movable clip 3 slides to the maximum distance, due to the first opening groove The distance between 212 and the bottom slope of the second opening groove 222 gradually increases, and the side pressure between the slider and the slide rail gradually decreases. When the maximum distance is reached, the slider It is in an adjustment state with the slide rail.

Preferably, in order to keep the heights of the first sliding block 21 and the second sliding block 22 the same during the up and down movement of the movable clip 3, the pendant assembly further includes a connecting rod 4, the left and right ends of the connecting rod 4 It is fixed to the first sliding block 21 and the second sliding block 22 and is located below the movable clip 3. In this embodiment, according to the difference between the movable clip 3 and the slider, the connecting rod can be set to a shape that matches the movable clip 3 and the slider. For example, the connecting rod is set as a square, Rhombus, L-shaped, T-shaped, etc., to achieve better bearing effect.

In this embodiment, as shown in FIG. 4, the pendant assembly further includes a fixing kit 5, the fixing kit 5 is fixed on the installation plane, the fixing kit 5 passes through the movable clip 3 and the connection Between the rods 4; when the movable clip 3 slides to the maximum distance, the pushing force generated by the fixing kit 5 on the movable clip 3 is gradually reduced, and the movable clip 3 acts on the sliding The side pressure of the block and the slide rail is gradually reduced, and the slider and the slide rail are in an adjusted state; when the movable clip slides toward the minimum distance, the fixing kit 5 pairs the movable clip The pushing force generated by the strip 3 gradually decreases and increases, the side pressure of the movable clip 3 on the sliding block and the sliding rail gradually increases, and the sliding block and the sliding rail are in a locked state.

Specifically, the fixing kit 5 includes a kit 51 and a fixing member 52 (not shown in the figure). The kit 51 has a first diameter structure 511 and a second diameter structure 512, wherein the first diameter structure 511 and The second diameter structures 512 are separated by protrusions, and the height of the protrusions is proportional to the elasticity of the material, so as to prevent the first diameter structure 511 and the second diameter structure 512 from sliding back and forth, ensuring the lock of the pendant assembly Effective separation of the tight state and the adjusted state; the fixing member 52 is fixed to the installation plane, preferably, the fixing member 52 is an expansion screw for fixing the pendant assembly to the installation plane of the wall;

When the sleeve 51 and the fixing member 52 cooperate with each other, the sleeve 51 is sleeved on the outside of the fixing member 52, the first diameter structure 511 is flush with the back of the sleeve 51, and the fixing member 52 is fixed on the installation plane of the wall. When in use, only the fixing kit 5 fixed on the wall is inserted into the gap between the movable clip 3 and the connecting rod 4, and the state of the fixing kit 5 is adjusted to realize the change of the locking state and the adjustment state.

In this embodiment, the vertical distance between the movable clip 3 and the connecting rod 4 located at the minimum distance is greater than the diameter corresponding to the first diameter structure 511 to ensure that in the adjusted state, the There will be no large friction between the movable clip 3 and the slider. The diameter corresponding to the first diameter structure 511 is smaller than the diameter corresponding to the second diameter structure 512, so as to ensure that the screen is separated from the When the wall is pulled out from the installation plane, the fixing kit 5 will not be separated from the gap between the movable clip 3 and the connecting rod 4.

In order to more clearly illustrate the use of the adjustable pendant assembly to achieve the locking state and the change of the adjustment state, the working process of the pendant assembly of the present invention will be described in more detail below in conjunction with FIGS. 5 and 6.

As shown in the side and front views of Figure 5 (a) and (b), when the first diameter structure 511 of the fixing kit 5 is located between the movable clip 3 and the connecting rod 4, due to the first diameter The diameter of the structure 511 is smaller than the minimum distance of the vertical distance between the movable clip 3 and the connecting rod 4. The movable clip 3 does not generate side pressure on the slider, which can move up and down along the slide rail , The adjustment function of the pendant assembly is completed, which is convenient for simple and convenient adjustment of the position.

As shown in the side and front views of Figures 6 (a) and (b), when the second diameter structure 512 of the fixing kit 5 is located between the movable clip 3 and the connecting rod 4, the fixing kit 5 will lift the movable clip 3 upwards, the movable clip 3 moves upward along the first opening groove 212 and the second opening groove 222, and pushes the first slider 21 and the second The sliding block 22 moves to the left and right sides respectively, so that the sliding block and the sliding rail contact surface form a relatively large pressure, thereby generating a relatively large static friction. Then, using the principle of gravity self-locking, the entire suspension assembly Slide to lock and complete the locking function of the pendant assembly.

According to the above working process, when the position needs to be adjusted, it is only necessary to pull out the screen to the installation plane where the wall is located, so that the first diameter structure 511 of the fixing kit 5 is located on the movable clip 3 and the connecting rod 4. In between, when the pendant assembly reaches the adjustment state, the slider can move up and down along the sliding rail, and the adjustment of the up and down positions can be completed without disassembling the screen from the wall. After adjusting the screen to a proper position, you only need to push the screen to the wall. The second diameter structure 511 of the fixing kit 5 is located between the movable clip 3 and the connecting rod 4, so that the The pendant assembly reaches the locked state, and at this time the entire pendant assembly is in a fixed state due to friction.

In this embodiment, when the gravity of the screen acts on the movable clip 3, the screen will further push the slider outwards to achieve gravity self-locking, making the structure more reliable. When the position needs to be adjusted again, an external force can be used to hold up the screen and apply a pulling force outward, so that the pendant assembly is restored to the adjustment state, and the position adjustment is realized again. Since the adjustment state and the locked state do not need to move the screen greatly when switching between the adjustment state and the locked state, it can ensure that the installer can perform unilateral operation, that is, when one side of the screen is in the adjustment state for adjustment, the other side of the screen can be in the locked state. Gravity, after adjusting the screen on one side, adjust the screen on the other side. Through this embodiment, single-person adjustment can be realized, the structure is simple, and the operation is efficient. Preferably, since the left and right sides of the screen can be adjusted separately, the present invention can also adapt to the special situation where the height of the screws on the left and right sides is inconsistent.

Further, the diameter of the second diameter structure 512 is related to the matching size between the components of the pendant assembly. Secondly, the diameter of the second diameter structure 512 is related to the material composition of the components of the pendant assembly. In this embodiment, when the material elasticity of the various components is good or the structural rigidity is low, the matching size can be made to take a relatively large value, and vice versa.

In order to further explain that the present utility model realizes the process of fixing and locking the screen position by means of the gravity self-locking, here, the realization conditions of the gravity self-locking are derived.

According to the foregoing description, during the gravity self-locking process, the second diameter structure 512 of the fixing kit 5 is in the gap between the movable clip 3 and the hanging rod 4. At this time, the slight deformation of the material of each component is ignored. , The simplified force situation is shown in Figure 7(a). In order to achieve gravity self-locking, the following conditions need to be met:

F ₁ sinα+μ ₁ F ₁ _{cosα≤F 0} /2 (1)

μ ₂ F ₂ ≥F ₀ /2 (2)

F ₁ cosα-μ ₁ F ₁ sinα=F ₀ cosβ (3)

F ₁ sinα+μ ₁ F ₁ cosα＜μ ₂ F ₂ (4)

In the formula, F ₀ is the force borne by either side of the pendant assembly of the present invention. In this embodiment, the pendant assembly is a structure where the left and right sides are arranged opposite to each other. Therefore, there is F ₀ = G/2, where G is the total gravity of the screen; F ₁ is the pressure perpendicular to the surface of the opening groove on _{the slider, and μ 1} is the static friction coefficient of the surface of the opening groove on the slider , Α is the angle between the opening groove on the slider and the vertical direction. F ₂ is the pressure perpendicular to the mating surface of the slider, μ ₂ is the static friction coefficient of the mating surface of the slider, and β is the angle between the groove and the vertical direction.

In the above formulas, formulas (1) and (2) can ensure that the movable clip 3 slides before the sliding block slides; it is ensured that the sliding block and the sliding rail can be slid up and down in the adjusted state; Equation (3) ensures that the slider is balanced in the horizontal direction to achieve a static state; Equation (4) can ensure a relatively large friction force between the slider and the slide rail, thereby realizing gravity self-locking.

According to (3)(4), we can get:

tanα＜(μ ₂ -μ ₁ cosβ)/(μ ₁ μ ₂ +cosβ) (5)

Clearly, the formula (5) is a monotonically decreasing function of the right side, [mu] is a monotonically increasing function μ ₁ of _2, so a ₂ [mu] larger, smaller, or the α μ ₁ is capable of a large range of values.

Of course, there are obvious differences in the friction coefficient between different materials. For example, the dry friction coefficient between aluminum and aluminum is about 1.1-1.7, while the friction coefficient between aluminum and steel is about 0.17. Therefore, in this embodiment, a reasonable choice can be made The material of each component further improves the self-locking performance of the pendant assembly.

The utility model is composed of a sliding rail, a sliding block and a movable clip. The two sliding blocks are respectively provided with a first opening groove and a second opening groove. The first opening groove and the second opening groove are at least One is an inclined groove, so that there is a maximum distance and a minimum distance between the first opening groove and the second opening groove. When the movable clip slides toward the minimum distance, the slider and the slide rail In the locked state, when the movable clip slides to the maximum distance, the slider and the slide rail are in an adjustment state.

By setting at least one of the first opening groove and the second opening groove to be an inclined groove, there is a maximum distance and a minimum distance between the groove bottom slopes of the first opening groove and the second opening groove. To achieve the locked state and adjustment state of the pendant assembly, when the position needs to be adjusted, the screen only needs to be pulled out to the installation plane where the wall is located, so that the pendant assembly reaches the adjusted state, and when the screen is adjusted to a proper level After the position, you only need to push the screen to the wall to make the pendant assembly reach the locked state; by setting the connecting rod, you can ensure that the first slider and the second slider are above and below the movable clip. The height during the movement is consistent to further ensure the reliability of the pendant assembly; by inserting the fixing kit into the gap between the movable clip and the connecting rod, it is only necessary to control the first diameter structure to be located between the movable clip and the movable clip. When the connecting rods are between, the adjustment state can be achieved, and when the second diameter structure is located between the movable clip and the connecting rods, with the aid of the gravity self-locking function, the locked state can be achieved, thereby The height of the screen can be adjusted without removing the screen, the installation and adjustment are simple, the structure is stable, and the operation is convenient.

The above are only the embodiments of the present utility model. It should be pointed out here that for those of ordinary skill in the art, improvements can be made without departing from the inventive concept of the present utility model, but these all belong to The scope of protection of the utility model.
