[0030] In order to make the technical personnel in the art better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.
[0031] The embodiment of the present application provides a contactor, as Figure 1 shown, the contactor comprises a contactor body 1 and a side hanging auxiliary 2, wherein the side hanging auxiliary 2 is connected with the side wall of the contactor body 1 through a hanging structure, and the embodiment does not make specific limitation to the hanging structure, which can be, for example, as Figure 1 shown, the contactor body 1 is provided with a first hanging structure 11, the side hanging auxiliary 2 is provided with a second hanging structure 21, and the side hanging auxiliary 2 is connected with the contactor body 1 through the hanging cooperation between the first hanging structure 11 and the second hanging structure 21, or the hanging structure can also be provided as a separate hanging piece, which can be hung with the contactor body 1 and the side hanging auxiliary 2 respectively, so as to realize the hanging connection between the contactor body 1 and the side hanging auxiliary 2 through the hanging piece.
[0032] The contactor body 1 further comprises a contact support 12, the contact support 12 is provided with an interface 121, and the side hanging auxiliary 2 further comprises a top rod 22, when the side hanging auxiliary 2 and the contactor body 1 are hung and connected, the top rod 22 can be inserted into the interface 121, and the contact support 12 can drive the top rod 22 to move through the interface 121, so as to realize the normal work of the side hanging auxiliary 2.
[0033] As Figure 2 shown, after the top rod 22 is inserted into the interface 121, the top rod 22 can move with the interface 121, and there is interaction between the top rod 22 and the inner wall of the interface 121, and in the process of moving with the interface 121, the top rod 22 is inevitably subjected to collision, abrasion and the like, so that the inner wall of the interface 121 and / or the outer wall of the top rod 22 are damaged, if the interface 121 is damaged, it may cause the parameters of the contact support 12 to change, and even affect the working condition of the side hanging auxiliary 2, so that it cannot work normally, and since the top rod 22 of the side hanging auxiliary 2 is in a cantilever state, when the top rod 22 is subjected to abrasion or impact, it may be broken.
[0034] Therefore, in the process of inserting the ejector rod 22 into the interface 121 and moving with the interface 121, in order to avoid the wear between the ejector rod 22 and the interface 121 affecting the work, in the embodiment, a buffer 3 is arranged between the ejector rod 22 and the interface 121. It is understood that the buffer 3 is of flexible material, and the hardness of the buffer 3 is lower than the hardness of the inner wall of the interface 121 and the hardness of the outer wall of the ejector rod 22. Therefore, the arrangement of the buffer 3 can avoid the direct impact between the ejector rod 22 and the inner wall of the interface 121 due to the long-time relative movement, and can reduce the wear between the outer wall of the ejector rod 22 and the inner wall of the interface 121, thereby protecting the interface 121 and the ejector rod 22, ensuring the service life of the two, and reducing the maintenance cost.
[0035] The buffer 3 is arranged between the interface 121 and the ejector rod 22, and therefore the buffer 3 is in a cylindrical structure. It is understood that when the buffer 3 is not arranged, the size of the interface 121 and the size of the ejector rod 22 can be arranged according to the related design to ensure that the side-hanging auxiliary 2 can work normally. When the buffer 3 is arranged, the size of the inner wall of the cylindrical buffer 3 corresponds to the size of the interface 121 when the buffer 3 is not arranged, so as to ensure that the side-hanging auxiliary 2 can work normally.
[0036] In the embodiment, the buffer 3 can be fixed to the inner wall of the interface 121 or fixed to the outer wall of the ejector rod 22. When the ejector rod 22 is inserted into the interface 121, the buffer 3 can achieve the buffering effect between the ejector rod 22 and the interface 121.
[0037] As shown in Figure 3 , when the buffer 3 is fixed to the inner wall of the interface 121, the buffer 3 and the interface 121 are detachably connected. In this way, when the buffer 3 is worn after long-time use, it can be directly detached and replaced, which is convenient to operate and good in economy.
[0038] Specifically, the detachable connection between the buffer 3 and the inner wall of the interface 121 is not limited. As shown in Figure 4 and Figure 5 , the outer wall of the buffer 3 is provided with a protrusion 4, and the inner wall of the interface 121 is provided with a groove 5. When the buffer 3 is inserted into the interface 121 and the protrusion 4 is located in the groove 5, the buffer 3 is fixed with the interface 121. That is, the protrusion 4 forms a first clamping member arranged on the buffer 3, the groove 5 forms a second clamping member arranged on the inner wall of the interface 121, and the protrusion 4 and the groove 5 are fixed by the cooperation of the first clamping member and the second clamping member. Specifically, the number of the first clamping member and the number of the second clamping member are not limited. As shown in Figure 5 , the opposite sides of the buffer 3 are respectively provided with protrusions 4, and the opposite side walls of the inner wall of the interface 121 are also respectively provided with grooves 5, that is, the number of the first clamping member and the number of the second clamping member are both two, which can further improve the installation stability.
[0039] Of course, the first clamping member can also be the groove 5, and the second clamping member is the protrusion 4, that is, the outer wall of the buffer 3 is provided with the groove 5, and the inner wall of the interface 121 is provided with the protrusion 4. Alternatively, the buffer 3 and the interface 121 can also be fixed through interference fit, and the clamping and fixing through the protrusion 4 and the groove 5 can simplify the installation operation compared with the fixing through interference fit.
[0040] When the first clamping member is the protrusion 4, that is, the inner wall of the interface 121 is provided with the protrusion 4, the outer end of the protrusion 4 is provided with the guide structure 41, wherein "outer" refers to the side facing the outside of the interface 121, and "inner" refers to the side facing the inside of the interface 121. The buffer 3 is inserted into the interface 121 from the outside to the inside and is fixed with the interface 121. The provision of the guide structure 41 is beneficial to the smooth insertion of the buffer 3 into the interface 121. Similarly, when the second clamping member is the protrusion 4, that is, the outer wall of the buffer 3 is provided with the protrusion 4, the inner end of the protrusion 4 is provided with the guide structure 41.
[0041] Further, the inner end and the outer end of the protrusion 4 are respectively provided with the guide structure 41. In this way, the disassembly and assembly of the buffer 3 are facilitated.
[0042] Specifically, the guide structure 41 can be a bevel or an arc surface, which is not limited here.
[0043] In the embodiment, the buffer 3 is a rubber sleeve, which forms the above-mentioned cylindrical structure. Alternatively, in the embodiment, the buffer 3 can also be a rubber pad and be fixed to the inner circumferential wall of the interface 121 or the outer circumferential wall of the ejector rod 22 by bonding to form the above-mentioned cylindrical structure.
[0044] Alternatively, in the embodiment, the buffer 3 can also be a plastic filler filled in the inner wall of the interface 121 or the outer wall of the ejector rod 22. Alternatively, the buffer 3 can also be a fabric layer and be fixed to the inner wall of the interface 121 or the outer wall of the ejector rod 22 by bonding.
[0045] The contact support 12 and the ejector rod 22 are plastic parts, wherein the contact support 12 is a thermosetting plastic part, and the ejector rod 22 is an injection molded plastic part.
[0046] The two side walls of the contactor body 1 can be respectively connected with the side hanging auxiliary 2 through the hanging structure. Correspondingly, as shown in Figure 2 The two sides of the contact support 12 are respectively provided with the interface 121, that is, the two sides of the contactor body 1 can be respectively hung with the side hanging auxiliary 2. Specifically, one side can be hung with the side hanging auxiliary 2, or both sides can be hung with the side hanging auxiliary 2, which can be set according to the specific situation.
[0047] The above merely is the preferred embodiment of the present application, it should be pointed out that, for ordinary skilled in the art, without departing from the principles of the present application, can also make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application.
