DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0026] The following describes in detail the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0027] The embodiment of the present application provides a connection structure. Figure 1 The connection structure 100 provided in the embodiment of the present application may include: a first connecting rod 120, a first insertion rod 130, and a support frame 110. The first connecting rod 120 may have a first end 1201, a second end 1202, and a first movable portion 1203; the first movable portion 1203 may be located between the first end 1201 and the second end 1202. The first movable portion 1203 may be movably connected to the support frame 110, the first insertion rod 130 may be slidably disposed on the support frame 110, the second end 1202 may be rotatably connected to the first insertion rod 130, and the first end 1201 may drive the first connecting rod 120 to rotate when driven, and the first connecting rod 120 may drive the first insertion rod 130 to slide.

[0028] In this manner, in the embodiments of the present application, the first connecting rod 120 can be rotated by driving the first end 1201, thereby driving the first insertion rod 130 to slide. Thus, when the first insertion rod 130 is in a slid-out state by driving the first end 1201, it engages with the associated plug-in portion 2101; when the first insertion rod 130 is retracted by driving the first end 1201, the retracted first insertion rod 130 can be disengaged from the associated plug-in portion 2101, thereby respectively connecting and disconnecting the objects to be connected. This connection structure, in which the driving force is transmitted via the connecting rod, does not pose the risk of snap-on breakage.

[0029] Optionally, in the embodiment of the present application, first rod 130 can have an extended state and a retracted state. When first rod 130 is in the extended state, the end of first rod 130 can be used to mate with plug-in portion 2101. When first rod 130 is in the retracted state, the end of first rod 130 can be detached from plug-in portion 2101. In this way, connecting and disconnecting objects can be achieved by driving first rod 130 between the extended state and the retracted state.

[0030] Optionally, in an embodiment of the present application, the connection structure 100 may further include an elastic element 150, which may be used to extend the first insertion rod 130. Thus, when the driving force on the first end 1201 is released, the first insertion rod 130 may be extended under the action of the elastic element 150.

[0031] It should be noted that in other embodiments of the present application, the elastic element 150 may not be provided. For example, the first end portion 1201 may be pulled outward to extend the first rod 130, and the friction between the extended first rod 130 and the inner wall of the connecting portion 2101 may be utilized to maintain the first rod 130 in the extended state. Other implementations are not listed here one by one.

[0032] Optionally, in an embodiment of the present application, the connection structure 100 may further include an operating member 140. The operating member 140 may be slidably disposed on the support frame 110, and the first end portion 1201 may be rotatably connected to the operating member 140. Thus, by operating the operating member 140, the first end portion 1201 may be driven to move.

[0033] Alternatively, in an embodiment of the present application, the first movable portion 1203 may be a strip-shaped hole provided on the first connecting rod 120, and the support frame 110 may include a support shaft 1101, which may be embedded in the first movable portion 1203 and slidable in the first movable portion 1203. In this way, the movement of the connecting structure 100 may be smoother.

[0034] Optionally, in an embodiment of the present application, the connection structure 100 may further include: an elastic element 150 ; the elastic element 150 may be a compression spring, and the operating member 140 may abut against a corresponding portion on the support frame 110 through the elastic element 150 .

[0035] It should be noted that in other embodiments of the present application, for example, the first insertion rod 130 may also abut against a corresponding portion of the support frame 110 via an elastic element 150, thereby allowing the first insertion rod 130 to remain in the extended state under the action of an elastic force. Furthermore, for example, a torsion spring may be provided on the first connecting rod 120, which can be used to twist the first connecting rod 120, thereby allowing the first insertion rod 130 to remain in the extended state under the action of an elastic force. Other embodiments are not listed here.

[0036] Optionally, in an embodiment of the present application, the connection structure 100 may further include: a second connecting rod 120a, and a second insertion rod 130a. The second connecting rod 120a may have a third end 1201a, a fourth end 1202a, and a second movable portion 1203a. The second movable portion 1203a may be located between the third end 1201a and the fourth end 1202a, and the second movable portion 1203a may be movably connected to the support frame 110. The second insertion rod 130a may be slidably disposed on the support frame 110, the fourth end 1202a may be rotatably connected to the second insertion rod 130a, and the third end 1201a may be rotatably connected to the operating member 140.

[0037] In addition, in the embodiment of the present application, the second connecting rod 120a can be configured with reference to the form of the first connecting rod 120, and the second insertion rod 130a can be configured with reference to the form of the first insertion rod 130. The second connecting rod 120a and the first connecting rod 120 can be symmetrically arranged along the operating member 140, and the second insertion rod 130a and the first insertion rod 130 can be symmetrically arranged along the operating member 140.

[0038] Optionally, in an embodiment of the present application, the support frame 110 may be provided with a first sliding hole (not labeled), in which the operating member 140 is slidably disposed. The support frame 110 may be provided with a second sliding hole (not labeled), in which the first insertion rod 130 is slidably disposed. The support frame 110 may be provided with a third sliding hole (not labeled), in which the second insertion rod 130a is slidably disposed.

[0039] The embodiment of the present application also provides a boiler. Figures 2 to 3 The boiler provided in the embodiments of the present application may include: a boiler housing 310, a temperature measuring device 200, and any one of the connection structures 100 provided in the embodiments of the present application. The connection structure 100 may be provided on one of the boiler housing 310 and the temperature measuring device 200, while the other may be provided with a plug-in portion 2101 for mating with the end of the first insertion rod 130. In this manner, the temperature measuring device 200 may be mounted on the boiler housing 310 using the connection structure 100.

[0040] For example, the boiler may include two connecting structures 100, which may be disposed in an upper and lower position relative to each other, thereby providing stability in the connection between the temperature measuring device 200 and the boiler housing 310. Of course, for example, in other embodiments of the present application, only one connecting structure 100 may be provided, and other snap-fit ​​structures may be provided at opposite locations.

[0041] Optionally, in an embodiment of the present application, the connection structure 100 may be provided on the boiler housing 310 , and the boiler may further include a connection block 210 , which may be provided on the temperature measuring device 200 , and a plug-in portion 2101 may be provided on the connection block 210 .

[0042] refer to Figures 4 and 5Optionally, in an embodiment of the present application, the temperature measuring device 200 may include: a housing 220 and a fastening mechanism 230. The housing 220 may be provided with a through hole (not shown) for the cable 400 to pass through. The fastening mechanism 230 may include: a connecting seat 2301 and a connecting ring 2302. The connecting seat 2301 may be provided at the through hole, and the connecting seat 2301 may be provided with a through hole that is connected to the through hole. A plurality of clamping blocks 23011 may be circumferentially spaced apart on the side of the connecting seat 2301 away from the housing 220. The outer periphery of the clamping blocks 23011 may be provided with a first thread, and the inner periphery of the connecting ring 2302 may be provided with a second thread, and the first thread may be mated with the second thread. In this way, the cable 400 can be passed through the through hole and the through hole, and the clamping blocks 23011 can be brought closer to each other by tightening the connecting ring 2302, so that the cable 400 can be clamped by the clamping blocks.

[0043] In this manner, in the embodiments of the present application, the first connecting rod 120 can be rotated by driving the first end 1201, thereby driving the first insertion rod 130 to slide. Thus, when the first insertion rod 130 is in a slid-out state by driving the first end 1201, it engages with the associated plug-in portion 2101; when the first insertion rod 130 is retracted by driving the first end 1201, the retracted first insertion rod 130 can be disengaged from the associated plug-in portion 2101, thereby respectively connecting and disconnecting the objects to be connected. This connection structure, in which the driving force is transmitted via the connecting rod, does not pose the risk of snap-on breakage.
