Based on this, in order to solve the above problem, the embodiment of the present application connects the device body 1 and the fixing band 2 through the telescopic assembly 3 as shown in fig. 2, so as to achieve quick detachment and installation of the fixing band 2.

As shown in fig. 2, the telescopic assembly 3 includes a housing 31, a lock lever 32 and a push rod 33. Wherein, the shell 31 is a hollow rod, the shell 31 includes a first end and a second end which are conducted, so that the shell 31 has a movable cavity with two ends conducted, and the lock rod 32 and the push rod 33 are both located in the movable cavity. The second end of the lock lever 32 passes through the first end of the housing 31 such that the lock lever 32 is located in the movable cavity of the housing 31 and the second end of the lock lever 32 is located at the first end of the movable cavity.

The locking rod 32 may be a solid rod or a hollow rod, and the second end of the locking rod 32 is movably connected with the first end of the push rod 33. Specifically, the push rod 33 is a hollow rod, the diameter of the second end of the lock rod 32 is smaller than that of the first end of the lock rod 32, and the second end of the lock rod 32 is movably connected in the inner cavity of the push rod 33. Illustratively, as shown in fig. 3, a first elastic member 35 may be disposed in the inner cavity of the push rod 33, and one end of the first elastic member 35 is fixed to the second end of the lock lever 32. The first end of the lock lever 32 is sleeved with a second elastic member 36, and one end of the second elastic member 36 is pressed against the end of the housing 31. In addition, a limit structure may be disposed on the inner wall of the housing 31, so that the lock lever 32 can be locked by the limit structure when pushed by the push rod 33.

The second end of the push rod 33 protrudes out of the other end of the movable cavity, so that the second end of the push rod 33 can be pressed, and the push rod 33 pushes the lock rod 32 to switch between the plugging state and the disconnecting state. Under the condition that the first end of the lock rod 32 is inserted into the limiting hole, the push rod 33 pushes the lock rod 32 along the first direction, and the first end of the lock rod 32 extends out of the movable cavity; in the case where the first end of the lock lever 32 is disengaged from the stopper hole, the first end of the lock lever 32 is retracted into the movable cavity, wherein the first direction is a direction close to the first end of the lock lever 32. Specifically, when a first elastic element 35 is arranged in the inner cavity of the push rod 33, and a second elastic element 36 is sleeved at the first end of the lock rod 32, the second end of the push rod 33 is pressed under the condition that the first end of the lock rod 32 is inserted into the limiting hole, so that the first elastic element 35 in the inner cavity of the lock rod 32 is compressed, and then the push rod 33 is loosened, so that the lock rod 32 moves along the first direction under the action of the elastic force of the first elastic element 35 until contacting with the limiting structure, so that the first end of the lock rod 32 extends out of the movable cavity, and the second elastic element 36 is compressed in the process. Thus, after the telescopic assembly 3 is fixed at the end of the fixing band 2, the first part of the locking rod 32 extending out of the movable cavity can be connected with the device body 1, and the second end of the push rod 33 is inserted into the device body 1, so that the fixing band 2 can be connected with the device body 1.

Under the condition that the first end of the lock rod 32 is separated from the limiting hole, the push rod 33 is pressed, so that the lock rod 32 rotates under the action of the push rod 33, the second end of the lock rod 32 is separated from the limiting structure, and the first end of the lock rod 32 is retracted into the movable cavity again under the action of the elastic force of the second elastic piece 36. In this way, when the first end of the lock lever 32 is separated from the device body 1, the fixing band 2 is separated from the device body 1, and the second end of the push rod 33 is inserted into the device body 1, the fixing band 2 can be separated from the device body 1 when the push rod 33 is pulled out from the device body 1.

It should be noted that, the middle portion of the push rod 33 has an accommodating cavity, a first elastic member 35 is disposed in the accommodating cavity, and a second elastic member 36 is sleeved at the first end of the lock lever 32. The first elastic member 35 and the second elastic member 36 may each be one of springs, one end of the first elastic member 35 may be fixed to the second end of the push rod 33, and the other end of the first elastic member 35 may be in contact with the second end of the push rod 33. Under the condition that the first end of the lock rod 32 is separated from the limiting hole, the first end of the lock rod 32 retracts into the movable cavity, so that the second end of the lock rod 32 abuts against the first elastic piece 35 to enable the first elastic piece 35 to be in a compressed state, then the second end of the push rod 33 is pressed, the first elastic piece 35 inside the push rod 33 is further compressed, the second end of the push rod 33 is loosened, the locking piece 34 can move towards the direction close to the first end of the lock rod 32 under the action of the elastic force of the first elastic piece 35, and then the first end of the lock rod 32 extends out of the movable cavity. Meanwhile, the second elastic member 36 is always in a compressed state during the process that the first end of the locking lever 32 is extended out of the movable chamber. In the process that the first end of the lock rod 32 is separated from the limiting hole, the second end of the push rod 33 is continuously pressed, and moves towards the direction away from the limiting hole under the action of the elastic force of the second elastic piece 36, and when the elastic force of the second elastic piece 36 and the elastic force of the first elastic piece 35 received by the lock rod 32 are balanced, the lock rod 32 is fixed in the movable cavity.

It should be further noted that the first elastic element 35 is in a compressed state in the process of inserting or separating the first end of the lock rod 32 from the limiting hole, so as to always provide the lock rod 32 with an elastic force away from the push rod 33. The second elastic member 36 is also in a compressed state during the process of inserting or removing the limit hole at the first end of the lock lever 32, thereby always giving the lock lever 32 an elastic force close to the push rod 33. When the elastic force of the first elastic member 35 is greater than the elastic force of the second elastic member 36, the lock lever 32 moves away from the push rod 33, so that the first end of the lock lever 32 approaches the position-limiting hole. When the elastic force of the first elastic member 35 is smaller than the elastic force of the second elastic member 36, the lock lever 32 moves toward the push rod 33, so that the first end of the lock lever 32 is away from the position-limiting hole.

As can be seen from the above embodiments, in the embodiment of the present application, since the push rod 33 has an accommodating cavity, a first elastic member 35 is disposed in the accommodating cavity, a first end of the lock lever 32 is sleeved with a second elastic member 36, one end of the first elastic member 35 is fixed at the bottom of the accommodating cavity, and the other end of the first elastic member 35 contacts with a second end of the push rod 33; the first end of the lock rod 32 is inserted into or separated from the limiting hole under the pushing of the push rod 33. Thus, when the fixing strap 2 is connected to the device body 1, the second end of the push rod 33 can be pressed, so that the first elastic piece 35 in the accommodating cavity inside the push rod 33 is compressed, and then the push rod 33 is loosened, so that the lock rod 32 moves in the direction close to the limiting hole under the action of the elastic force of the first elastic piece 35 until the first end of the lock rod 32 extends out of the movable cavity, and the second end of the push rod 33 is inserted into the device body 1 to connect the fixing strap 2 and the device body 1. When the device body 1 and the fixing band 2 are detached, because the first end of the lock rod 32 extends out of the movable cavity, the second elastic member 36 is always in a compressed state, and the second end of the push rod 33 is pressed again, so that the first end of the lock rod 32 retracts into the movable cavity again under the action of the elastic force of the second elastic member 36 to separate the fixing band 2 from the device body 1. Therefore, the whole process of disassembly and assembly can be completed without the help of a special disassembling tool, the operation of a user is facilitated, the whole process mainly pushes the lock rod 32 by the push rod 33, the disassembly and assembly of the fixing belt 2 and the equipment main body 1 are realized under the action of the elastic force of the first elastic element 35 and the second elastic element 36, the impact force of the whole process telescopic assembly 3 is small, the risk of connection failure between the fixing belt 2 and the equipment main body 1 is reduced, and the service life of the fixing belt 2 is prolonged.

Alternatively, as shown in fig. 3 and 4, the second end of the lock lever 32 is provided with a locking member 34; the second end of the locking piece 34 is movably connected with the push rod 33; the second end of the locking member 34 includes a plurality of guiding ribs 341, as shown in fig. 6, the inner wall of the first end of the housing 31 is provided with a plurality of guiding grooves and shoulders 312; the guide groove extends toward the first end of the housing 31, and the shoulder 312 includes a limiting surface, the limiting surface is spaced from the end of the housing 31 by a first distance, wherein the first end of the housing 31 is the end for mounting the push rod 33; under the condition that the first end of the lock rod 32 is inserted into the limiting hole, the end part of the guide rib 341 is pressed against the limiting surface; in the case where the first end of the lock lever 32 is disengaged from the stopper hole, the guide rib 341 is positioned in the guide groove.

Specifically, the diameter of the second end of the lock rod 32 is smaller than that of the first end of the lock rod 32, the first end of the lock member 34 has an inner cavity, the second end of the lock rod 32 can be inserted into the inner cavity of the lock member 34, and the second end of the lock rod 32 and the first end of the lock member 34 are in interference fit, so that the lock member 34 and the lock rod 32 are fixed more firmly. Next, the second end of the locking member 34 includes a plurality of guiding ribs 341, each guiding rib 341 protrudes from the outer surface of the locking member 34, and the guiding ribs 341 extend along the length of the locking member 34.

The inner wall of the first end of the housing 31 is formed with a plurality of guide grooves and a shoulder 312, wherein the guide grooves extend toward the first end of the housing 31, and the shoulder 312 includes a limiting surface. Thus, under the condition that the first end of the lock rod 32 is inserted into the limiting hole, the guide rib 341 can be separated from the limiting groove 311 through the push rod 33, and finally the end portion of the guide rib 341 is pressed against the limiting surface, and because the first distance is formed between the limiting surface and the end portion of the housing 31, the first distance is also formed between the second end of the housing 31 and the end portion of the housing 31, so that the first end of the locking member 34 extends out of the housing 31. In the case that the first end of the lock lever 32 is disengaged from the position-limiting hole, the end of the guide rib 341 may be disengaged from the shoulder 312 by the push rod 33 and finally be positioned in the position-limiting groove 311, thereby allowing the first end of the locking member 34 to be retracted back into the housing 31. It should be noted that under the combined action of the guide groove and the guide rib 341, the locking member 34 can be stably in the insertion state or the separation state under the limiting action of the shoulder 312 of the guide groove in the process of inserting or separating the locking member 34 into or from the limiting hole at the first end of the lock rod 32.

As shown in FIG. 7, on the inclined surface, the object is subjected to gravity G, positive pressure N, frictional force f, and component G of gravity G₂In balance with the positive pressure N, when the inclination angle θ is greater than the critical angle, the component of gravity greater than G1 is greater than or equal to the friction force f, and the object slides in the direction of inclination of the inclined surface. Based on this principle, when the end of the guiding rib 341 is the end inclined surface 3411, the surface of the limiting surface is an inclined surface, and the surface gradient of the limiting surface is the same as the surface gradient of the end inclined surface 3411, in this way, the principle of inclined surface sliding can be utilized, so that the end inclined surface 3411 slides along the limiting surface, and then the locking piece 34 is driven to rotate, and further the locking rod 32 is switched between the plugging state or the separation state. In addition, it should be noted that the notch of the guiding groove also has an inclined surface, and the surface gradient of the inclined surface is the same as the surface gradient of the stop inclined surface 3411, and a shoulder 312 is provided between every two adjacent limiting grooves 311, so that the lock lever 32 can be continuously switched between the plugging state and the separation state.
