Description

Technical Field

[0001] The utility model relates to the technical field of combination switches, in particular to a combination switch that can be disassembled and replaced individually. Background Art

[0002] Combination switches typically combine two or more switches to increase their contact capacity. The additional switches are typically connected to the two switch bodies via mounting holes. For example, in patent publication number "CN205828206U," entitled "A Combination Switch," bolts pass through two holes on the left and right sides of the switch connection plate to form a bolted connection to the switch body. A boss is positioned at the top of the switch body, embedded in a hole in the spring. The button is located in the middle of the push rod connection plate. However, this structure presents the following problems in actual use:

[0003] The above-mentioned combination switch combines two sets of switch bodies by bolts. However, when one of the switches needs to be replaced, it is very inconvenient and the process is time-consuming and labor-intensive. At the same time, when the number of switch combinations exceeds two, it is even more difficult to disassemble and replace the switches that need to be replaced separately, and the practicality is relatively poor.

[0004] Therefore, we have proposed a combination switch that can be removed and replaced separately to solve the above problems. Utility Model Content

[0005] The purpose of the present utility model is to provide a combination switch that can be disassembled and replaced individually, so as to solve the problems raised in the above-mentioned background art in the current market, such as the inconvenience of replacing one group of switches, the time-consuming and labor-intensive process, and the relatively poor practicality of the problem that it is difficult to disassemble and replace the switches that need to be replaced individually when the number of switch combinations exceeds two groups.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a combination switch that can be individually disassembled and replaced, comprising a housing and a switch body mounted on the upper end surface of the housing for control;

[0007] The invention also includes: a connecting foot is fixed on the lower end surface of the shell, a slide groove is opened on the right side of the shell, and a connecting slider is fixed on the left side of the shell, and a sliding connection is formed between the slide groove and the connecting slider;

[0008] The upper end surface of the shell is provided with a pressure rod, and the lower end of the pressure rod extends to the interior of the shell and forms a sliding connection with the shell. In addition, the lower end of the pressure rod is provided with a disassembly mechanism, which drives the limit slider to slide through the fixed rod to release the limit and realize disassembly.

[0009] Preferably, the disassembly mechanism includes an extension rod and a connecting rod, wherein the extension rod is fixed on both sides of the lower end of the pressure rod, and the outer end of the extension rod is rotatably connected to one end of the connecting rod.

[0010] Preferably, the lower end of the connecting rod is rotatably connected to the fixing rod, and the outer end of the fixing rod is fixed to the limiting slider.

[0011] Preferably, the limit slider is arranged inside the shell, and one end of the limit slider extends into the slide groove, and one side of the upper end surface of the limit slider is arranged as an inclined structure.

[0012] Preferably, the limiting slider is elastically slidably connected to the housing via a return spring, and both ends of the return spring are fixed to the housing and the limiting slider respectively.

[0013] Preferably, a clamping hole is provided on the outer side of the pressure rod, and the clamping hole and one end of the clamping rod form a clamping structure, while the other end of the clamping rod is fixed to the shifting block.

[0014] Preferably, the shift block is arranged on one side of the pressure rod on the upper surface of the shell, and the shift block is elastically slidably connected to the shell through a pressure spring, and both ends of the pressure spring are fixed to the shell and the shift block respectively.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the individually removable and replaceable combination switch is not only convenient for completing the individual removal and replacement of the switch, but also the removal process is simple and convenient. Whether it is a combination of two or more sets of switches, the function of individual removal and replacement can be realized. At the same time, the pressure rod can be limited to prevent workers from accidentally touching it and causing it to loosen. The specific contents are as follows:

[0016] By moving the pressure rod downward, it drives the connecting rod down together through the extension rod, so that the connecting rod drives the limit slider to slide to the left through the fixed rod, so that the right end of the limit slider no longer limits the connecting slider. At this time, the connecting slider can be slid out of the slide slot, thereby completing the individual disassembly and replacement of the switch. The disassembly process is simple and convenient. Whether it is a combination of two or more sets of switches, the function of disassembly and replacement can be realized separately.

[0017] Furthermore, a sliding connection is formed between the limit slider and the housing. When the connecting rod descends, since the limit slider can only slide left and right but cannot descend, the connecting rod will drive the limit slider to slide to the left through the fixed rod;

[0018] When the connecting slider moves to contact the upper end surface of the limit slider, when the connecting slider continues to apply downward pressure, it is forced to slide to one side. When the connecting slider is completely moved to the bottom of the slide groove, the limit slider is no longer restricted. At this time, the elastic force of the reset spring can drive the limit slider to reset, so that the limit slider limits the connecting slider, thereby completing the installation.

[0019] The elastic force of the pressure spring drives the shift block to move to one side, so that when the shift block moves, the fixed clamping rod moves together, so that one end of the clamping rod moves into the clamping hole to form a clamping connection with it, thereby limiting the pressure rod and preventing it from being loosened due to accidental touch by workers;

[0020] Furthermore, when the limit needs to be released, it is only necessary to push the shift block to the other side, so that the shift block drives the clamping rod to move to one side, thereby separating one end of the clamping rod from the clamping hole, thereby releasing the limit on the pressure rod, and the pressure rod can now be pressed.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1-6 , the utility model provides the following technical solutions:

[0030] Embodiment 1: In order to solve the problems in the prior art that when it is necessary to replace one set of switches, it is very inconvenient, the process is time-consuming and labor-intensive, and when the number of switch combinations exceeds two, it is even more difficult to disassemble and replace the switches that need to be replaced individually, and the practicality is relatively poor, the following solution is disclosed, including a housing 1 and a switch body 2 mounted on the upper end surface of the housing 1 for control; further comprising: a connecting foot 3 is fixed to the lower end surface of the housing 1, a slide groove 4 is opened on the right side of the housing 1, and a connecting slider 5 is fixed on the left side of the housing 1, and the slide groove 4 and the connecting slider are connected. 5 forms a sliding connection between them; a pressure rod 6 is provided on the upper end surface of the shell 1, and the lower end of the pressure rod 6 extends to the interior of the shell 1 and forms a sliding connection with the shell 1, and a disassembly mechanism is provided at the lower end of the pressure rod 6, which drives the limit slider 10 to slide through the fixed rod 9 to release the limit and realize disassembly, and the disassembly mechanism includes an extension rod 7 and a connecting rod 8, wherein the extension rod 7 is fixed on both sides of the lower end of the pressure rod 6, and the outer end of the extension rod 7 is rotatably connected to one end of the connecting rod 8, the lower end of the connecting rod 8 is rotatably connected to the fixed rod 9, and the outer end of the fixed rod 9 is fixed to the limit slider 10.

[0031] First, the combination switch consists of a shell 1 and a switch body 2. The switch body 2 is used to open and close the switch. At the same time, the connection foot 3 at the lower end of the shell 1 is connected to the power body. At this time, the switch can be used. When one of the switches needs to be replaced, the pressure rod 6 can be pressed to force the pressure rod 6 to move downward. The pressure rod 6 moves downward, and then drives the extension rod 7 fixed at its lower end to move downward together. At the same time, one end of the connecting rod 8 is rotatably connected to the extension rod 7. When the extension rod 7 descends, it also drives the connecting rod 8 to descend together. The other end of the connecting rod 8 is connected to the fixed rod 9 to form a Rotational connection, while the fixed rod 9 and the limit slider 10 form a fixed structure, and a sliding connection is formed between the limit slider 10 and the housing 1. When the connecting rod 8 descends, since the limit slider 10 can only slide left and right but cannot descend, the connecting rod 8 will drive the limit slider 10 to slide to the left through the fixed rod 9, so that the right end of the limit slider 10 no longer limits the connecting slider 5. At this time, the connecting slider 5 can be slid out of the slide groove 4, thereby completing the separate disassembly and replacement of the switch, and the disassembly process is simple and convenient. Regardless of whether it is a combination of two groups or more than two groups of switches, the function of disassembly and replacement can be realized separately.

[0032] Example 2: Add a new technical solution based on Example 1 to achieve the installation and fixation of the switch. For details, refer to Figure 3-Figure 5 The limit slider 10 is arranged inside the shell 1, and one end of the limit slider 10 extends into the slide groove 4, and one side of the upper end surface of the limit slider 10 is arranged with an inclined structure. The limit slider 10 is elastically slidingly connected to the shell 1 through a return spring 11, and the two ends of the return spring 11 are respectively fixed to the shell 1 and the limit slider 10.

[0033] When replacing a new switch, it is only necessary to align the connecting slider 5 on one group of housings 1 with the slide groove 4 on the other group of housings 1, and then slide the connecting slider 5 into the slide groove 4. When the connecting slider 5 moves to contact the upper end surface of the limit slider 10, when the connecting slider 5 continues to apply downward pressure, the inclined structure of the upper end surface of the limit slider 10 is set, so that it is forced to slide to one side. When the connecting slider 5 moves completely to the bottom of the slide groove 4, the limit slider 10 will no longer be restricted. At this time, the limit slider 10 can be driven to reset by the elastic force of the reset spring 11, so that the limit slider 10 limits the connecting slider 5, and the installation is completed.

[0034] Example 3: Based on Example 1, a new technical solution is added to limit the pressure rod 6, thereby preventing the worker from accidentally touching it and causing it to loosen. For details, refer to Figure 2-Figure 6A card hole 15 is provided on the outside of the pressure rod 6, and the card hole 15 and one end of the card rod 14 form a card engagement structure. At the same time, the other end of the card rod 14 is fixed to the shift block 12. The shift block 12 is arranged on one side of the pressure rod 6 on the upper surface of the shell 1. At the same time, the shift block 12 is elastically slidingly connected to the shell 1 through a pressure spring 13, and the two ends of the pressure spring 13 are respectively fixed to the shell 1 and the shift block 12.

[0035] When the limit slider 10 is reset, it will also drive the fixed rod 9 to reset together. The fixed rod 9 is reset, and the connecting rod 8 is driven by the rotation of the connected connecting rod 8 to move the extension rod 7 upward, so that the extension rod 7 drives the fixed pressure rod 6 to reset upward. When the pressure rod 6 drives the clamping hole 15 to move parallel to the clamping rod 14, the elastic force of the pressure spring 13 can be used to drive the shift block 12 to move to one side, so that when the shift block 12 moves, the fixed clamping rod 14 moves together, so that one end of the clamping rod 14 moves into the clamping hole 15 to form a clamping connection with it, thereby limiting the pressure rod 6, thereby preventing the worker from accidentally touching it and causing it to loosen. At the same time, when the limit needs to be released, it is only necessary to shift the shift block 12 to the other side, so that the shift block 12 drives the clamping rod 14 to move to one side, so that one end of the clamping rod 14 is separated from the clamping hole 15, thereby releasing the limit on the pressure rod 6, and the pressure rod 6 can be pressed.

[0036] The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
