Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In the following, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, the meaning of "multiple" is two or more.

[0024] Reference Figures 1 to 6 The cabinet door pusher shown in the figure comprises a base 1, a pusher core 3 and a decorative cover 2. The decorative cover 2 can cover the base 1 and form a receiving cavity 16 between the decorative cover 2 and the base 1. The pusher core 3 is installed in the receiving cavity 16. The base 1 is provided with at least one through hole 17. The base 1 is fixedly connected to the side wall of the furniture cabinet 4 by a fixing element 18 (such as a screw) passing through the through hole 17. In some preferred embodiments, the base 1 is provided with at least two through holes 17, and at least one through hole 17 is set as a waist-shaped hole to facilitate the adjustment of the position of the base on the furniture cabinet 4. Of course, an expansion pin can also be set on the base 1 and fixed to the side wall of the furniture cabinet 4 through the expansion pin. The expansion pin can be designed as an integral molding with the base 1. A first protrusion 11 is provided at one end of the base 1, and a second protrusion 21 extending inward is also provided at the corresponding end of the decorative cover 2. When installed, the other end of the decorative cover 2 is inserted into the base 1, and the end with the second protrusion 21 moves toward the base 1 until the second protrusion 21 passes over the first protrusion 11 and is fixedly engaged with the first protrusion 11. After being fixed, the decorative cover 2 can completely cover the base 1 to achieve an aesthetic effect. A clearance groove 12 is provided at a position close to the end / first protrusion 11 on the base 1. When disassembling, a person manually presses the position of the decorative cover 2 corresponding to the clearance groove 12 to make the position concave, and then the end of the decorative cover 2 with the second protrusion 21 is deformed outward, so that the second protrusion 21 is separated from the first protrusion 11, and then the decorative cover 2 is removed from the base 1. The structure is simple and the operation is convenient.

[0025] In some possible embodiments, reference Figure 1 and Figure 3As shown, there are two giving way grooves 12 which are symmetrically opened on the opposite sides of the base 1, and two marking parts 22 are also arranged on the outer side of the decorative cover 2 at positions corresponding to the giving way grooves 12. The marking parts 22 can be grooves, protrusions or patterns formed on the outer surface of the decorative cover 2. When a person touches the marking part 22, he can know that pressing or pinching the place can separate the second protrusion 21 from the first protrusion 11, and then one end of the decorative cover 2 can be lifted up to remove the decorative cover 2 from the base 1.

[0026] In some possible embodiments, reference Figure 1 and Figure 5 As shown, the first protrusion 11 extends outward along the length direction of the base 1, and the upper side of the first protrusion 11 forms a first inclined guide surface 111, and the lower side of the first protrusion 11 forms a first inclined self-locking surface 112. Taking the vertical plane as the reference plane, the slope of the first inclined guide surface 111 is smaller than the slope of the first inclined self-locking surface 112, and the slope angle of the first inclined guide surface 111 is opposite to the slope angle of the first inclined self-locking surface 112. During installation, the second protrusion 21 moves downward along the first inclined guide surface 111 and gradually deforms the decorative cover 2 until the second protrusion 21 passes over the first inclined guide surface 111 and is clamped and fixed with the first inclined self-locking surface 112. During disassembly, the two sides of the decorative cover 2 are pressed manually to deform the decorative cover 2 to the outside of the second protrusion 21 and separate from the first inclined self-locking surface 112, and the one end of the decorative cover 2 is lifted manually to allow the second protrusion 21 to pass over the first inclined self-locking surface 112. The second protrusion 21 can move upward along the first inclined guide surface 111 autonomously under the action of the elastic restoring force of the decorative cover 2 material itself, so that it is convenient for people to remove the decorative cover 2 from the base 1 by hand, and the operation is simple and convenient; further, the second protrusion 21 extends inward from the inner side of the rear end of the decorative cover 2 along the horizontal length direction of the decorative cover 2, and the upper side surface of the second protrusion 21 forms a second inclined self-locking surface 212, and the lower side surface of the second protrusion 21 forms a second inclined guide surface 211. Taking the vertical plane as the reference plane, the slope of the second inclined guide surface 211 is smaller than the slope of the second inclined self-locking surface 212, and the slope angle of the second inclined guide surface 211 is opposite to the slope angle of the second inclined self-locking surface 212. Such a design can make the installation feel smoother and avoid jamming. In addition, the geometric shape design of the second inclined self-locking surface 212 and the first inclined self-locking surface 112 can enhance their self-locking properties.

[0027] In some possible embodiments, reference Figure 5 As shown, the second inclined self-locking surface 212 and the second inclined guide surface 211 are connected in an arc-shaped transition, and further, the arc is a circular arc, the purpose of which is to reduce the contact area between the second protrusion 21 and the first protrusion 11 when the second protrusion 21 moves relative to the first protrusion 11, thereby reducing friction resistance.

[0028] In some possible embodiments, reference Figure 1 and Figure 5 As shown, a baffle 13 extending upward is provided at the rear end of the base 1, and a first protrusion 11 is provided at the lower end of the baffle 13, and an arc-shaped guide surface 131 is formed at the upper end of the baffle 13. The baffle 13 and the base 1 are integrally formed. Due to the inherent elasticity of the materials of the base 1 and the baffle 13, the baffle 13 can absorb the impact force transmitted from the push core 3 when the push core 3 is hit; in this embodiment, the base 1 and the other end of the decorative cover 2 are detachably connected by rotation. After the other end is initially connected, the second protrusion 21 abuts against the arc-shaped guide surface 131 at the upper end of the baffle 13. By pressing the upper side of the decorative cover 2 by hand, the second protrusion 21 can be driven to move along the arc-shaped guide surface 131 to the first inclined guide surface 111, and after crossing the first inclined guide surface 111, the first inclined self-locking surface 112 and the second inclined self-locking surface 212 are finally self-lockingly engaged, thereby realizing the fixed installation of the decorative cover 2 and the base 1.

[0029] In some possible embodiments, reference Figure 1 and Figure 6 As shown, a card block 14 is provided at the other end of the base 1, and a card slot 23 is provided at the corresponding end of the decorative cover 2. The card block 14 extends horizontally outward along the length direction of the base 1. This embodiment is described by taking the card block 14 being arranged at the front end of the base 1 and the first protrusion 11 being arranged at the rear end of the base 1 as an example. During specific installation, the card block 14 can be inserted or partially inserted into the card slot 23, and one end of the decorative cover 2 is pressed to make the second protrusion 21 move from top to bottom along the arc-shaped guide surface 131 and the first inclined guide surface 111, and finally the first inclined self-locking surface 112 and the second inclined self-locking surface 212 reach a self-locking card connection state.

[0030] In some possible embodiments, reference Figure 1 and Figure 6 As shown, a guide portion 141 is provided at the front end of the block 14, the thickness of the guide portion 141 is smaller than that of the block 14, and the cross-section of the guide portion 141 is trapezoidal. During installation, the guide portion 141 can be smoothly inserted into the slot 23 and is convenient for the decorative cover 2 to use the connection between the block 14 and the slot 23 as a rotation point, so that the rear end of the decorative cover 2 can be rotated by a certain angle, that is, when the second protrusion 21 moves from top to bottom along the first inclined guide surface 111, the guide portion 141 / block 14 is always partially located in the slot 23 to avoid the decorative cover 2 and the base 1 from being separated at this end. As the second protrusion 21 gradually passes over the peak of the first inclined guide surface 111 and reaches a self-locking and fixed state with the first inclined self-locking surface 112, the block 14 is finally stably engaged with the slot 23, thereby cooperating with the first protrusion 11 and the second protrusion 21 to fix the decorative cover 2 on the base 1.

[0031] In some possible embodiments, reference Figure 6As shown, one end of the decorative cover 2 is provided with a first stopper 231 and a second stopper 232 spaced apart in an upper and lower manner, and a slot 23 is formed between the first stopper 231 and the second stopper 232. When installing, the decorative cover 2 is moved along its length direction in a manner that this end is tilted and fits the base 1, so that the card block 14 penetrates the card slot 23, and at this time, the rear end of the decorative cover 2 can cover the baffle 13 extending upward, and then the rear end of the decorative cover 2 is pressed to make the second protrusion 21 move downward along the baffle 13 and finally be snap-connected and fixed with the first protrusion 11; when disassembling, it is only necessary to manually pinch the positions with the marking portions 22 on both sides of the decorative cover 2 to deform the rear end of the decorative cover 2 and separate and unlock the second protrusion 21 from the first protrusion 11, and then lift the rear end of the decorative cover 2 to make the second protrusion 21 move upward along the baffle 13. At this time, the decorative cover 2 and the base 1 are relatively tilted, and then the decorative cover 2 is translated along its axial direction until the card block 14 is separated from the card slot, and then the decorative cover 2 can be removed from the base 1.

[0032] In some possible embodiments, a countersunk space 15 is formed on the outer side of the base 1 around the through hole 17 , and the countersunk space 15 is used to hide wood chips so that the base 1 can better fit the installation surface of the furniture cabinet 4 .

[0033] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
