Description

Technical Field

[0001] The utility model relates to the technical field of foam products, in particular to a novel foam adhesive backing pad. Background Art

[0002] See also Figure 1 , Figure 1 The schematic diagram of the reciprocating sliding structure in the prior art includes a base 5 and a slider 4 that reciprocates in the height direction relative to the base 5. The top surface of the base 5 is equipped with four first guide posts 41 and second guide posts 51, and the first guide posts 41 and second guide posts 51 are both used for guiding. In the actual working process, the bottom surface of the slider 4 will frequently contact the top surface of the base 5. Since the power driving the slider 4 to slide is large, when the slider 4 touches the base 5, the slider 4 or the base 5 is prone to cracking or damage. In order to solve the problem of the slider 4 directly touching the base 5, a rectangular foam gasket 6 is attached to the bottom surface of the slider 4. The foam gasket 6 is attached to the bottom surface of the slider 4 by an adhesive. The foam gasket 6 can play a role in mitigating the impact. However, after a long period of work, the bonding force between the foam gasket 6 and the slider 4 is attenuated, and the foam gasket 6 is easy to peel off the bottom surface of the slider 4, resulting in a short service life, thereby affecting the working stability of the equipment. Utility Model Content

[0003] The utility model aims to provide a novel foam adhesive backing pad in view of the deficiencies in the prior art, and the foam adhesive backing pad can solve the problem of short service life.

[0004] The purpose of the utility model is achieved through the following technical scheme: the application provides a new foam-backed adhesive gasket, including a foam sheet, a window is opened in the middle of the foam sheet, four through holes are opened on the top surface of the foam sheet and are evenly distributed on the outer peripheral side of the window, the four through holes are arranged in a matrix, and a groove is also formed on the lower side of the foam sheet; the top end surface of the foam sheet is coated with adhesive.

[0005] The thickness of the foam sheet is 1 mm to 3 mm.

[0006] Among them, the thickness of the foam sheet is 1.55mm.

[0007] There is an opening between each through hole and the outer peripheral side of the foam sheet, one end of the opening is connected to the corresponding through hole, and the other end of the opening is connected to the outside.

[0008] The ratio of the width of the opening to the diameter of the through hole is 1:5.

[0009] The groove is arranged in a U shape.

[0010] Wherein, a backing release film is attached to the bottom end surface of the foam sheet.

[0011] The novel foam backing gasket of the utility model has the following beneficial effects:

[0012] (1) By opening four through holes on the foam sheet, each through hole can be inserted with a first guide column, so that the foam sheet can be limited by the guide column. Even if the bonding force between the foam sheet and the slider is weakened, the foam sheet will not be offset relative to the slider, thereby extending the bonding time between the foam sheet and the slider. Even if the bonding force between the foam sheet and the slider is lost, the foam sheet will not fall out from between the slider and the foam sheet, thereby ensuring the normal operation of the equipment, extending the service life of the foam backing gasket, and solving the problem of short service life in the past.

[0013] (2) By opening the window, the material used for the foam sheet can be reduced, and the production cost of the foam backing gasket can be reduced, thereby improving economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described in conjunction with the following embodiments.

[0019] A specific implementation method of a novel foam backing gasket of the utility model is as follows Figure 2 As shown, the foam backing adhesive pad includes a foam sheet 1, an adhesive layer 2 located above the foam sheet 1, and a backing release film 3 located below the foam sheet 1. It should be noted that the adhesive layer 2 is composed of an adhesive coated on the top surface of the foam sheet 1. As a preferred solution, the adhesive model can be 3M-55256 double-sided adhesive. The backing release film 3 prevents direct contact between the foam sheets 1 when two foam backing adhesive pads are stacked and stored, and plays a role of isolation and protection.

[0020] As an improvement, a window 11 is provided in the middle of the foam sheet 1, and four through holes 12 are provided on the top surface of the foam sheet 1, which are evenly distributed on the outer peripheral side of the window 11. The four through holes 12 are arranged in a matrix, and a groove 13 is also formed on the lower side of the foam sheet 1. The four through holes 12 are mainly for the insertion of the external first guide column 41. The through holes 12 cooperate with the first guide column 41 to limit the foam sheet 1, and the groove 13 cooperates with the second guide column 51 to mainly play the role of avoiding position. As a preferred solution, the groove 13 is set in a U shape.

[0021] Optionally, the thickness of the foam sheet 1 is 1 mm to 3 mm. As a preferred solution, the thickness of the foam sheet 1 is 1.55 mm, which can provide effective protection and save materials to the greatest extent.

[0022] In order to more conveniently assemble the foam adhesive backing gasket, an opening 14 is provided between each through hole 12 and the outer peripheral side of the foam sheet 1, one end of the opening 14 is connected to the corresponding through hole 12, and the other end of the opening 14 is connected to the outside. When assembling the foam adhesive backing gasket, the through hole 12 of the foam sheet 1 can be sleeved on the outside of the guide column through the opening 14, which makes the assembly more convenient and quick. Optionally, the ratio of the width of the opening 14 to the diameter of the through hole 12 is 1:5.

[0023] A new foam backing adhesive gasket of this embodiment is provided with four through holes 12 on the foam sheet 1, each through hole 12 can be inserted with a first guide column 41, so that the foam sheet 1 is limited by the guide column. Even if the bonding force between the foam sheet 1 and the slider 4 is weakened, the foam sheet 1 will not be offset relative to the slider 4, and the time for the foam sheet 1 and the slider 4 to be attached is extended. Even if the bonding force between the foam sheet 1 and the slider 4 is lost, the foam sheet 1 will not fall out between the slider 4 and the foam sheet 1, which can ensure the normal operation of the equipment, extend the service life of the foam backing adhesive gasket, and solve the problem of short service life in the past. In addition, by providing the window 11, the material used for the foam sheet 1 is reduced, the production cost of the foam backing adhesive gasket is reduced, and the economic benefits can be improved.

[0024] 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.
