Description

Technical Field

[0001] This utility model relates to the field of pressure strip technology, specifically to an assembled pressure strip. Background Technology

[0002] A molding strip is a strip-shaped component used to cover gaps, protect edges, or fix materials. It offers advantages such as preventing dust accumulation and enhancing overall aesthetics, preventing damage from bumps and knocks during use, avoiding scratches from sharp edges of boards, countertops, or wall corners, and increasing structural stability. It is widely used in decoration, furniture, doors, and windows.

[0003] A pressure strip typically consists of a base and a main cover plate. During installation, the base is first fixedly connected to the ground, and then the main cover plate is snapped into place with the base using clips and slots.

[0004] However, in actual use, due to long-term impact and shaking, the connection between the main cover plate of the pressure strip and the base will wear down over time, causing the gap at the connection to continuously increase. This can lead to loosening of the connection between the two and even the main cover plate falling off the base. Utility Model Content

[0005] To address the aforementioned issues, an assembly-type pressure strip is provided. This strip enhances the assembly stability of the cover plate and base body by incorporating elastic sheets and protrusions that expand the elastic sheets at the main engagement points. Insert blocks one and two reinforce the limiting portion between the cover plate and base body, preventing the cover plate from easily detaching from the base body during compression deformation. A sliding plate, constrained by the compression of insert block two and the engagement portion, works in conjunction with the engagement portion and connecting groove to achieve dual lateral and vertical limiting of the cover plate, improving assembly effectiveness and post-assembly tightness.

[0006] To address the existing technical problems, this utility model provides an assembled pressure strip, including a base body and a cover plate body disposed above the base body, wherein a connecting groove is recessed in the middle of the base body;

[0007] The middle part of the cover plate body extends vertically downward to form a snap-fit ​​part that mates with the connecting groove. The snap-fit ​​part has a pressing groove recessed on both sides. The protruding parts of two adjacent pressing grooves at the snap-fit ​​part are abutting parts. The inner walls on both sides of the connecting groove extend in the direction of the snap-fit ​​part to form a limiting part that mates with the abutting part.

[0008] The snap-fit ​​part has a vertically open mounting groove at the bottom. The mounting groove is provided with an elastic piece. Both the elastic piece and the mounting groove are arched with the arc surface at the top. Both ends of the bottom of the elastic piece are fixedly installed with the snap-fit ​​part, and a buffer gap is left between the outer surface of the elastic piece and the inner surface of the arched groove.

[0009] The inner wall at the bottom of the connecting groove extends vertically to form a protrusion. The protrusion is a triangular prism, and its vertically upward part extends into the mounting groove and then gradually tapers inward to form a pointed tip.

[0010] Preferably, the cover plate body is symmetrically provided with insert block 1 and insert block 2 about the plane containing its axis of symmetry, and the base body is provided with mating groove 1 and mating groove 2 that cooperate with insert block 1 and insert block 2. Insert block 1 and insert block 2 are located at the bottom of the cover plate body and near its end.

[0011] Preferably, each of the two-way connecting grooves extends horizontally in the direction of the docking groove to form a sliding groove communicating with it, and a sliding plate that can move along the lateral extension direction of the sliding groove is also provided in the sliding groove.

[0012] Preferably, the top angle of each sliding plate facing the second insert is inclined, and the two sides of the snap-fit ​​portion are recessed inward to form a transverse positioning groove that cooperates with the sliding plate.

[0013] Preferably, the two insert blocks are arranged in a vertical hook shape with opposite orientations, and the vertical plane of the insert blocks is tightly fitted with the end of the sliding plate. The part of the cover plate body located between the docking groove one and the docking groove two forms an inverted "L" shape that cooperates with the vertical hook-shaped insert blocks two.

[0014] Preferably, the cover plate body is symmetrically provided with a bottom-open strip groove about the plane containing its axis of symmetry, and the strip groove is an inverted "V" shape.

[0015] Preferably, it also includes a rubber strip disposed in the strip groove and attached to the inner wall of the strip groove.

[0016] Preferably, the protrusion is located in the middle of the connecting groove, and the mounting groove and the elastic piece are both located in the middle of the snap-fit ​​portion.

[0017] The advantages of this utility model compared to the prior art are:

[0018] 1. By setting elastic pieces and protrusions that expand the elastic pieces at the main snap-fit ​​positions of the cover plate body and the base body, the snap-fit ​​part is pushed and squeezed to both sides so that the abutting part and the limiting part at the connecting groove are always in a tight abutting state, thereby enhancing the assembly stability of the two and preventing them from loosening later.

[0019] 2. By setting insert block one and insert block two to enhance the limiting part between the cover plate body and the base body, the cover plate body is less likely to detach from the base body during the process of being squeezed and deformed.

[0020] 3. A sliding plate is set up that is limited by the squeezing action of the second insert and the snap-fit ​​part. It works with the snap-fit ​​part and the connecting groove to achieve dual limitation of the cover plate body in both the lateral and vertical directions, which improves its assembly effect and the tightness after assembly.

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] See Figure 1 and Figure 2 As shown, an assembled pressure strip includes a base body 1 and a cover plate body 2 disposed above the base body 1. A connecting groove is recessed in the middle of the base body 1.

[0029] The cover plate body 2 extends vertically downward in the middle to form a snap-fit ​​part that cooperates with the connecting groove. The snap-fit ​​part has a compression groove on both sides. The protruding parts of two adjacent compression grooves at the snap-fit ​​part are abutment parts. The inner walls on both sides of the connecting groove extend in the direction of the snap-fit ​​part to form a limiting part that cooperates with the abutment part.

[0030] It should be noted that during installation, the snap-fit ​​part at the bottom of the cover plate body 2 is aligned with the connecting groove in the middle of the base body 1 and pressed down. At this time, the limiting part will squeeze the abutment parts on both sides of the snap-fit ​​part. The abutment parts will deform within the allowable range of the squeezing grooves on both sides until the snap-fit ​​part is fully inserted into the connecting groove. Then the abutment parts will return to their original state and abut against the lower surface of the limiting part to achieve the snap-fit ​​effect.

[0031] See Figure 1-3 As shown, the snap-fit ​​part has a vertically open mounting groove at the bottom. The mounting groove is provided with an elastic piece 3. Both the elastic piece 3 and the mounting groove are arched with the arc surface located directly above. Both ends of the bottom of the elastic piece 3 are fixedly installed with the snap-fit ​​part, and a buffer gap is left between the outer surface of the elastic piece 3 and the inner surface of the arched groove.

[0032] It should be noted that the elastic sheet 3, when compressed, allows the abutment portion to retract more smoothly, facilitating the connection between the abutment portion and the limiting portion. Simultaneously, when the abutment portion is no longer pressed down, the elastic sheet 3, under its own elastic force, pushes the abutment portion towards the limiting portion, ensuring a tight fit between the two and enhancing the locking effect between the cover plate body 2 and the base body 1.

[0033] Furthermore, when the abutting part and the limiting part are worn, the elastic piece 3 can still push the abutting part under its own elastic force, and push the abutting part to both sides, so that the abutting part and the limiting part are always in a tight abutting state, which makes the connection more stable and the service life can be greatly extended.

[0034] See Figure 2 and Figure 4 As shown, the inner wall at the bottom of the connecting groove extends vertically to form a protrusion 1a. The protrusion 1a is a triangular prism, and its vertically upward part extends into the mounting groove and then gradually contracts inward to form a pointed part.

[0035] It should be noted that the protrusion 1a is designed to increase the overall strength of the snap-fit ​​part while the auxiliary elastic sheet 3 is extended to both sides, effectively preventing the problem of weakened strength after the middle of the snap-fit ​​part is slotted. The protrusion 1a is designed as a triangular prism to facilitate its connection with the elastic sheet 3.

[0036] See Figure 1-3 As shown, the cover plate body 2 is symmetrically provided with insert block 2a and insert block 2b about the plane containing its axis of symmetry. The base body 1 is provided with mating groove 1 and mating groove 2 that cooperate with insert block 2a and insert block 2b. Insert block 2a and insert block 2b are located at the bottom of the cover plate body 2 and near its end.

[0037] It should be noted that by setting insert 2a and insert 2b to enhance the limiting part between the cover plate body 2 and the base body 1, the cover plate body 2 is less likely to detach from the base body 1 during the process of being squeezed and deformed.

[0038] See Figure 2 and Figure 5 As shown, each of the two-way connecting grooves extends horizontally in the direction of the docking groove to form a sliding groove that communicates with it, and a sliding plate 4 that can move along the lateral extension direction of the sliding groove is also provided in the sliding groove.

[0039] The top angle of each sliding plate 4 facing the second insert 2b is inclined, and the two sides of the snap-fit ​​part are recessed inward to form a transverse positioning groove that cooperates with the sliding plate 4.

[0040] It should be noted that during installation, insert 2a and insert 2b will connect to mating groove 1 and mating groove 2 simultaneously. At this time, the bottom of insert 2b will gradually contact the inclined top corner of sliding plate 4, thereby squeezing and pushing sliding plate 4 along sliding groove until sliding plate 4 connects with transverse positioning groove, thus completing the transverse limiting of the snap-fit ​​part.

[0041] This achieves dual lateral and vertical limiting of the cover plate body 2, improving its assembly effect and the tightness after assembly.

[0042] See Figure 2 and Figure 3 As shown, the two insert blocks 2b are arranged in a vertical hook shape with opposite orientations, and the vertical plane of the insert blocks 2b is closely fitted with the end of the sliding plate 4. The part of the cover plate body 2 located between the docking groove 1 and the docking groove 2 forms an inverted "L" shape that cooperates with the vertical hook-shaped insert blocks 2b.

[0043] It should be noted that the "L"-shaped arrangement of the part of the cover plate body 2 located between the first and second docking grooves and the vertical hook-shaped arrangement of the second insert 2b allow the two to restrain each other, further enhancing the limiting effect when the cover plate body 2 and the base body 1 are assembled.

[0044] See Figure 1-3 As shown, the cover plate body 2 is symmetrically provided with a bottom-open strip groove about the plane containing its axis of symmetry. The strip groove is an inverted "V" shape.

[0045] It also includes a rubber strip 5 that is set in the strip groove and adheres to the inner wall of the strip groove.

[0046] It should be noted that, in order to avoid problems such as cracking caused by excessive compression of the cover plate body 2 by heavy objects, the strip groove can provide deformation and buffer space for the cover plate body 2 after being compressed. At the same time, the rubber strip 5 is used to enhance the support and recovery of the deformation space, further improving the stability of the assembled pressure strip during use.

[0047] See Figure 2 As shown, the protrusion 1a is located in the middle of the connecting groove, and the mounting groove and the elastic piece 3 are both located in the middle of the snap-fit ​​part.

[0048] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
