TECHNICAL FIELD

[0001] The utility model belongs to a kind of hardware fittings, and especially a kind of cabinet door pressing type rebound opener with simple structure. BACKGROUND

[0002] In order to achieve the buffering effect, the existing cabinet door is equipped with a rebound opener. When the cabinet door needs to be opened, the door is pressed and the rebound effect of the rebound opener opens the door. When the door is closed, the rebound opener provides a buffering effect. Many rebound openers use magnetic attraction to tightly attract the door to the cabinet. However, the magnetic attraction is not strong enough. To overcome this defect, some existing rebound openers use buckles. For example, a cabinet door pressing type rebound opener is disclosed in application No. 202322707109.6. The buckle locks the ball to close the door. However, the clamping blocks on both sides of the buckle rotate around the mounting shaft to clamp and release the ball. The installation is complex, and the entire structure has two springs, making the overall structure more complex. SUMMARY

[0018] The utility model will be further explained in detail in connection with the drawings.

[0019] Reference Figures 1-5 The cabinet door pressing type rebound opener with simple structure comprises a base 1, a buckle column 2, a sleeve 3, a top rod 4, a buckle 5 and a rebound device 6, the buckle column 2 is fixed on the base 1, the sleeve 3 is provided with a containing cavity 31, the top rod 4 is sleeved in the containing cavity 31, the rebound device 6 is located in the containing cavity 31, one end of the top rod 4 is connected with the rebound device 6, the buckle 5 is arranged at the other end of the top rod 4, the other end of the top rod 4 can extend out of the sleeve 3, the buckle 5 comprises clamping edges 51, the clamping edges 51 are two and oppositely arranged, the inner side walls of the clamping edges 51 are all arc-shaped, a clamping groove 52 is formed between the two clamping edges 51, and the front end of the buckle column 2 can be clamped into the clamping groove 52.

[0020] The buckle 5 is an injection molding part, so that the two clamping edges 51 can have a certain elasticity, when the front end of the buckle column 2 is inserted into or pulled out of the clamping groove 52, the opening of the clamping groove 52 can be extruded outward, facilitating the smooth insertion and pulling out of the buckle column 2.

[0021] In actual use, the front end of the buckle column 2 is formed with a locking ball 21, and the locking ball 21 can be inserted into the clamping groove 52. The width of the opening of the clamping groove 52 is less than the maximum width of the locking ball 21, and the middle width of the clamping groove 52 is greater than the maximum width of the locking ball 21, so as to ensure that the clamping groove 52 has sufficient locking force on the locking ball 21. Therefore, when the locking ball 21 is inserted into the clamping groove 52, an external force is needed to drive the cabinet door, so that the cabinet door drives the locking ball 21 to be pressed into the clamping groove 52. When the cabinet door needs to be opened, an external force needs to be applied to the cabinet door to pull the cabinet door to drive the locking ball 21 out of the clamping groove 52, so as to separate the buckle column 2 from the clamping groove 52, facilitating the opening of the cabinet door.

[0022] The cabinet door pressing type rebound opener with simple structure is used, the base 1 is fixed on the cabinet door through a screw, the sleeve 3 is fixed on the cabinet, when the cabinet door is opened, the base 1 and the buckle column 1 are opened with the cabinet door, and are separated from the buckle 5; when the cabinet door is closed, the front end of the buckle column 1 is inserted into the clamping groove 52, the buckle column 1 is locked through the clamping groove 52, so that the cabinet door remains in the closed state.

[0023] The buckle 5 further comprises a mounting rod 53, the top rod 4 is a hollow structure, a hollow hole 41 is formed, and the mounting rod 53 is matched with the hollow hole 41. When the buckle 5 is installed, the mounting rod 53 is inserted into the hollow hole 41, so as to realize the fixation of the buckle 5 on the top rod 4.

[0024] The hollow hole 41 is provided with an internal thread near one end of the rebound device, the rebound device 6 comprises a sliding block 61 connected with one end of the top rod 4, the sliding block 61 is provided with a screw rod 611, and the screw rod 611 is in threaded cooperation with the hollow hole 41.

[0025] The rebound device 6 further comprises a spring 62 and a hook 63, the spring 62 is sleeved outside the sliding block 61, the hook 63 is fixed in the sleeve 3, the sliding block 61 is provided with a sliding groove 613, and the hook 63 is correspondingly arranged at the sliding groove 613.

[0026] Both sides of one end of the top rod 4 are provided with through holes 42, and the outer sides of the two clamping edges 51 are located at the through holes 42. Therefore, when the locking ball 21 extrudes the clamping edges 51 to the two sides, the clamping edges 51 can be deformed outward to a certain extent through the through holes 42, so that the locking ball 21 and the clamping groove can be matched and separated.

[0027] The sliding block 61 is formed with a limiting block 612, the limiting block 612 is located on the sliding groove 613, the hook 63 corresponds to the limiting block 612, that is, the hook 63 can be hooked on the limiting block 612, so that the spring 62 is kept in a compressed state.

[0028] The cabinet door pressing type rebound opener with a simple structure further comprises a rear cover 7, the rear cover 7 is arranged at the rear end of the sleeve 3, the hook 63 is fixed on the rear cover 7, and the spring 62 abuts against the rear cover 7. By arranging the rear cover 7, the hook 63 can be conveniently fixed and installed in the accommodating cavity 31.

[0029] When the cabinet door is in a closed state, the hook 63 moves along the sliding groove 613 until it is hooked on the limiting block 612, the limiting block 612 can limit and fix the hook 63, so that the top rod is prevented from being pushed outwards; at this time, the spring 62 is in a compressed state.

[0030] The cabinet door pressing type rebound opener with a simple structure has a simple overall structure, does not need two springs, and realizes locking of the cabinet door through cooperation of the clamping groove and the locking ball, so that the locking force of the cabinet door when the cabinet door is closed is ensured.

[0031] When the cabinet door needs to be opened, the cabinet door is pressed, the force is transmitted to the top rod and the sliding block 61, the limiting block 612 is separated from the hook, the sliding block 61 and the top rod 3 are driven to move outward under the rebound force of the spring 62, the buckle 5 moves outward together with the top rod 3, at this time, the cabinet door is bounced open. When the through hole 42 moves to the outside of the sleeve 1, the external force is applied to the cabinet door to open the cabinet door, the locking ball 21 is separated from the clamping groove, and the cabinet door is convenient to open.

[0032] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the inventive concept, a number of modifications and improvements can be made, and these all belong to the protection scope of the present application.
