Description

Technical Field

[0001] The utility model relates to the technical field of rubber products, in particular to a 90-degree rubber pad. Background Art

[0002] In order to prevent the appliance from directly contacting the pad, existing household appliances generally have a plurality of spaced-apart gaskets or foot pads on the bottom surface of the appliance.

[0003] For some electrical appliances that have special requirements for installation, such as refrigerators and washing machines, the side or back of the refrigerator needs to be a certain distance away from the wall, mainly to leave enough space for the fan to intake air. Therefore, installers usually attach a rubber block to the side or back of the refrigerator to prevent the user from moving the refrigerator close to the wall. The washing machine will produce a certain vibration during operation. If the washing machine is close to the wall or cabinet, the washing machine will hit the surrounding objects, causing abnormal noise. In this regard, the installer will also attach a rubber block to the side of the washing machine. However, the rubber block attached to the side of the appliance is different from the rubber block on the bottom of the appliance. The rubber block attached to the side is generally fixed by adhesive. After long-term use, the adhesive fails, causing the rubber block to fall off, resulting in a short service life.

[0025] The utility model is further described in conjunction with the following embodiments.

[0026] A specific implementation of a 90-degree rubber pad of the utility model is as follows Figure 1 and Figure 2 As shown, it includes an L-shaped fixing sheet 3, a first rubber block 1 and a second rubber block 2. The second rubber block 2 is vertically arranged on the top surface of the first rubber block 1, and the L-shaped fixing sheet 3 is embedded in the first rubber block 1 and the second rubber block 2.

[0027] Please see Figure 1 The second rubber block 2 extends a protrusion 21 toward the first rubber block 1, and the second rubber block 2 is provided with a slot 11. Optionally, the cross-sectional shape of the protrusion 21 is an inverted T-shaped arrangement, and the cross-sectional shape of the slot 11 is an inverted T-shaped arrangement. The T-shaped structure can prevent the second rubber block 2 from being pulled upward after assembly, thereby limiting the freedom of the second rubber block 2 in the vertical direction. In other embodiments, the protrusion 21 and the slot 11 can both be set in a dovetail shape.

[0028] Please see Figure 2 A second groove 22 is formed on the rear end face of the second rubber block 2. The opening of the second groove 22 is connected to the bottom face of the locking protrusion 21. The depth of the second groove 22 is smaller than the width of the second rubber block 2. That is, the second groove 22 is not through the rear end face of the second rubber block 2 to the front end face of the second rubber block 2. Instead, the second groove 22 is a structure similar to a blind hole. When the L-shaped fixing sheet 3 is inserted into the second groove 22, the bottom of the second groove 22 can limit the insertion depth of the L-shaped fixing sheet 3.

[0029] Please see Figure 1 A first groove 12 is formed on the front end surface of the first rubber block 1. The opening of the first groove 12 is connected to the bottom of the slot 11. The depth of the first groove 12 is smaller than the width of the first rubber block 1. Similarly, the first groove 12 is not through the front end surface of the first rubber block 1 to the rear end surface of the first rubber block 1. Instead, the first groove 12 is a structure similar to a blind hole. When the L-shaped fixing sheet 3 is inserted into the first groove 12, the bottom of the first groove 12 can limit the insertion depth of the L-shaped fixing sheet 3.

[0030] The assembly process of a 90-degree rubber pad of the utility model is as follows: first, the longitudinal section of the L-shaped fixing sheet 3 is inserted into the second groove 22 of the second rubber block 2, and then the second rubber block 2 and the L-shaped fixing sheet 3 are moved to the outside of the front end surface of the first rubber block 1, and then the transverse section of the L-shaped fixing sheet 3 is inserted into the first groove 12 of the first rubber block 1. At the same time, the protrusion 21 of the second rubber block 2 is aligned with the groove 11 of the first rubber block 1, and the protrusion 21 is slid into the groove 11. When the front end surface of the first rubber block 1 is flush with the front end surface of the second rubber block 2, the assembly of the rubber pad is completed. Through the cooperation of the first groove 12, the second groove 22 and the L-shaped fixing sheet 3, the second rubber block 2 is limited to be plugged and installed only from one direction, and the installation position of the second rubber block 2 can be limited, making the assembly more convenient.

[0031] It should be noted that the second groove 22 is in a straight strip shape and is L-shaped. In the assembled state, the opening of the second groove 22 is connected to the opening of the first groove 12 , and the L-shaped fixing sheet 3 is inserted into the second groove 22 and the first groove 12 .

[0032] As a preferred solution, Figure 3 , the length of the second groove 22 is smaller than the length of the second rubber block 2, and the length of the first groove 12 is smaller than the length of the first rubber block 1, so that the L-shaped fixing sheet 3 can be prevented from being exposed, and the structural strength of the first rubber block 1 and the second rubber block 2 can be improved. In addition, the width of the L-shaped fixing sheet 3 is smaller than the depth of the first groove 12 or the depth of the second groove 22, so that the first rubber block 1 and the second rubber block 2 cannot be aligned due to the excessive width of the L-shaped fixing sheet 3.

[0033] Preferably, the L-shaped fixing plate 3 is a metal structure, that is, the L-shaped fixing plate 3 is made of an iron sheet or a steel sheet. In other embodiments, the L-shaped fixing plate 3 may also be a plastic structure.

[0034] Combination Figure 3 The bottom surface of the first rubber block 1 is provided with a through hole 41 penetrating to the top surface of the first rubber block 1, and the lower end of the inner wall of the through hole 41 is formed with a conical surface. The L-shaped fixing plate 3 is provided with a mounting hole 42 aligned with the through hole 41, so that it is more convenient for the rubber foot pad to be fixedly connected to the housing of the electrical appliance through external screws.

[0035] The 90-degree rubber pad of the present embodiment replaces the previous installation method of attaching the second rubber block 2 with an adhesive by providing a first rubber block 1 and a second rubber block 2 vertically plugged into the first rubber block 1, thereby avoiding the problem of the second rubber block 2 peeling off the side of the electrical appliance, extending the service life of the rubber pad, and solving the problem of short service life in the past. The first rubber block 1 and the second rubber block 2 adopt a plug-in structure, which is convenient and quick to assemble, has a simple and compact structure, and has a low manufacturing cost. By adding an L-shaped fixing plate 3, the structural strength of the rubber pad is further improved, and the service life of the banana pad is further extended.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
