Description

Technical Field

[0001] The invention relates to the technical field of transmission chain block manufacturing, in particular to a novel transmission chain block. Background Art

[0002] At present, common transmission chain blocks are usually composed of a rubber pad and a support base assembled with a transmission chain, which are bonded together by glue, and the rubber pad is installed on the top surface of the support base; however, the viscosity of the glue will affect the firmness of the connection between the rubber pad and the support base. Even if glue with good viscosity is used, after long-term use, the dried glue between the support base and the rubber pad is prone to cracking and falling due to external factors, affecting the firmness of the connection between the rubber pad and the support base. In addition, when the rubber pad and the support base are bonded together with glue, the glue between the rubber pad and the support base needs a certain amount of time to dry, which is not conducive to improving the production efficiency of the transmission chain blocks. Summary of the Invention

[0003] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a new transmission chain block with a firm connection.

[0004] The present invention achieves the above object by:

[0005] The present invention provides a new type of transmission chain block, including a base and a rubber pad. The base is formed by a base, a connector and a support platform connected together. The base, the connector and the support platform are connected in sequence from bottom to top. The edge of the support platform protrudes outward relative to the connector and extends to form a flange. The edge of the rubber pad extends downward and bends to form a connecting flange. The connecting flange wraps the flange.

[0006] Furthermore, the top edge of the base body protrudes outward relative to the connector and the flange.

[0007] Furthermore, the base is also provided with a plurality of connecting countersunk holes, which penetrate longitudinally from the top surface of the support platform to the bottom surface of the base body. The bottom of the rubber pad is provided with a plurality of connecting columns which are integrally connected to it and protrude downward, and the plurality of connecting columns are assembled with the connecting countersunk holes.

[0008] Furthermore, a plurality of limiting grooves are provided on the side surface of the connector, and the limiting grooves are arranged longitudinally. The connecting flange also protrudes outward to form a plurality of connecting ridges, and the connecting ridges are assembled with the limiting grooves.

[0009] Furthermore, the flange is also provided with a reinforcement countersunk hole.

[0010] Furthermore, the bottom of the rubber pad is also provided with a connecting column protruding downward and assembled with the reinforcing countersunk hole. The connecting column passes through the reinforcing countersunk hole and is connected to the connecting flange as a whole.

[0011] Furthermore, the limiting groove is located below the reinforced countersunk hole, and the upper edge of the limiting groove is connected to the lower edge of the reinforced countersunk hole; the connecting ridge is also connected to the connecting column as a whole.

[0012] Beneficial effects of the present invention:

[0025] On the base 1, the edge of the supporting platform 13 is protruded and extended outward relative to the connecting body 12 to form the flange 130, and the edge of the rubber pad 2 is extended and bent downward to form a connecting flange 21. The connecting flange 21 wraps the flange 130 and is interlocked with the flange 130. The flange 130 presses the connecting flange 21 against, for example, the connecting flange 21 is pressed against the top surface of the base 11, thereby preventing the rubber pad 2 from shaking up and down and falling off, making the connection between the rubber pad 2 and the base 1 more secure. Moreover, compared with the prior art, the connection between the rubber pad 2 and the base 1 is not achieved by glue, but by the mutual cooperation between the flange 130 and the connecting flange 21. Since the connecting flange 21 wraps the flange 130, the flange 130 and the connecting flange 21 always maintain a mutually interlocked state, thereby keeping the rubber pad 2 connected to the base 1, and the connection is more secure and stable.

[0026] Furthermore, in this embodiment, Figure 2 、 Figure 3 As shown, the top edge of the base 11 protrudes outward relative to the connector 12 and the flange 130, and the connecting flange 21 cooperates with the flange 130, the connector 12, and the top surface of the base 11; in other embodiments, the flange 130 may protrude from the top surface of the base 11.

[0027] Furthermore, in order to make the connection between the rubber pad 2 and the base 1 more firm and stable, in this embodiment, Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 As shown, the base 1 is also provided with a plurality of connecting countersunk holes 14, and the connecting countersunk holes 14 penetrate longitudinally from the top surface of the supporting platform 13 to the bottom surface of the base 11. The bottom of the rubber pad 2 is provided with a plurality of connecting columns 22 which are connected thereto and protrude downward. The plurality of connecting columns 22 are assembled with the connecting countersunk holes 14.

[0028] Furthermore, in this embodiment, Figure 8 As shown, the bottom surface of the base 11 of the base 1 is provided with a plurality of longitudinal and transverse reinforcing ribs 111, and the longitudinal and transverse reinforcing ribs 111 form grid grooves 112 with each other, and each grid groove 112 has at least one connecting countersunk hole 14; the connecting column 22 passes through the connecting countersunk hole 14, protrudes from the connecting countersunk hole 14, and is also located in the grid groove 112.

[0029] Furthermore, in this embodiment, Figure 4 、 Figure 5 、 Figure 6 As shown, the side of the connecting body 12 is also provided with a plurality of limiting grooves 121, and the limiting grooves 121 are arranged longitudinally. The connecting flange 21 also protrudes outward to form a plurality of connecting ridges 211, and the connecting ridges 211 are assembled with the limiting grooves 121. The connecting ridges 211 cooperate with the limiting grooves 121 to prevent the rubber pad 2 from shaking back and forth and / or left and right, and to avoid the rubber pad 2 from falling off, so that the connection between the rubber pad 2 and the base 1 is more secure; in other embodiments, the connecting body 12 can be provided with the limiting grooves 121, and the connecting flange 21 can be provided with connecting ridges 211 that cooperate with the limiting grooves 121, and the connecting ridges 211 are connected to the connecting flange 21 as a whole.

[0030] Furthermore, in this embodiment, in order to keep the thickness of the flange 130 consistent and change the stress state of the flange 130, the hardness of the flange 130 is increased, as shown in FIG. Figure 4 As shown, the flange 130 is further provided with a reinforcement countersunk hole 131 .

[0031] Furthermore, in this embodiment, Figure 6As shown, the bottom of the rubber pad 2 is also provided with a downwardly protruding connecting column 212, and the connecting column 212 is assembled with the reinforced countersunk hole 131. The connecting column 212 also passes through the reinforced countersunk hole 131 and is connected to the connecting flange 21 as a whole. The connecting column 212 is connected to the connecting flange 21 as a whole, so that the rubber pad 2 and the base 1 are fixed together to prevent the rubber pad 2 from falling off, and ensure that the connection between the rubber pad 2 and the base 1 is firm and stable.

[0032] Furthermore, in this embodiment, Figure 2 、 Figure 6 As shown, the limiting groove 121 is located below the reinforcing countersunk hole 131 , and the upper edge of the limiting groove 121 is connected to the lower edge of the reinforcing countersunk hole 131 , and the connecting protrusion 211 is also connected to the connecting column 212 as a whole.
