Description

Technical Field

[0001] This utility model relates to the field of torch technology, specifically to a handheld torch that is easy to assemble and disassemble. Background Technology

[0002] Handheld torches, as important lighting and symbolic devices, are widely used in events such as the Olympics and large-scale activities. In existing technologies, to facilitate torch storage and the installation of internal components, torches are typically divided into upper and lower shells for disassembly and assembly. For example, the handheld torch disclosed in Chinese Patent CN214370183U specifically describes a structure where "the lower end of the outer shell (i.e., the upper shell) has an internal thread, and the upper end of the handheld component (i.e., the lower shell) has an external thread and a limiting part; the internal and external threaded parts are threadedly connected, and the end face of the internal thread abuts against the limiting part." In other words, in existing technologies, the outer shell and handheld component are mostly fixed using a simple threaded connection. However, this threaded connection method has certain drawbacks: the torch is prone to loosening after vigorous movement or prolonged use, leading to structural instability and even safety hazards, thus reducing connection reliability; furthermore, the assembly and disassembly process is relatively time-consuming, hindering the quick replacement of fuel canisters, etc.

[0003] Therefore, there is still much room for improvement in the disassembly and assembly of this type of handheld torch in the existing technology to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a handheld torch that is easy to assemble and disassemble and has better stability.

[0005] To solve the above-mentioned technical problems, the technical solution used in this utility model is as follows:

[0006] A handheld torch that is easy to assemble and disassemble includes an upper shell and a lower shell, which are detachably connected. A sleeve is provided inside the upper shell near the lower shell, and an installation cavity is formed within the sleeve. An insertion port communicating with the installation cavity is provided at the bottom of the sleeve. A connector is provided at the lower shell near the upper shell, and the connector can be inserted into the installation cavity through the insertion port to connect with the sleeve. An elastic element is provided on the outer side of the sleeve, the elastic element having a first locking portion, and the connector having a second locking portion. When the connector is inserted into the installation cavity, the first locking portion engages with the second locking portion to fix the upper shell and the lower shell.

[0007] Preferably, the elastic element includes a mounting section and a snap-fit ​​section connected to each other. The snap-fit ​​section is fixed to the sleeve through the mounting section. The first snap-fit ​​portion is provided on the snap-fit ​​section. When the plug is inserted into the mounting cavity, the first snap-fit ​​portion can abut against the second snap-fit ​​portion. When the plug is connected to the sleeve, a groove is formed to accommodate the snap-fit ​​section. At least a portion of the snap-fit ​​section abuts against the groove wall.

[0008] Preferably, the connector has a first groove, and the sleeve has a second groove opposite to the first groove. When the connector is inserted into the mounting cavity, the first groove and the second groove cooperate to form the retaining groove.

[0009] The buckle section includes a bent edge, which is the first snap-fit ​​part; the second snap-fit ​​part is a boss, which is disposed on the top of the first groove and extends outward along the radial direction of the first groove, and the bent edge can abut against the boss.

[0010] Preferably, the snap-fit ​​segment further includes a fixed edge and an elastic compression edge. The first end of the bent edge is connected to the mounting segment, the second end of the bent edge is connected to the fixed edge, and the other end of the fixed edge is connected to the elastic compression edge. The end of the elastic compression edge extends away from the fixed edge and abuts against the groove wall of the second groove. A deformation space that can elastically deform in the radial direction is formed between the elastic compression edge and the fixed edge.

[0011] Preferably, the bent edge forms an angle with the horizontal line, and the angle is 30°±5°.

[0012] Preferably, the radial width of the deformation space in its natural state is 1-5 mm.

[0013] Preferably, the elastic element has a first positioning hole extending through its thickness direction; the sleeve has a second positioning hole that mates with the first positioning hole; the first positioning hole and the second positioning hole are locked together by fasteners to fix the elastic element to the sleeve.

[0014] Preferably, the sleeve is further provided with a guide groove extending along its axial direction, and the plug is provided with a positioning rib extending along its axial direction. The guide groove and the positioning rib are matched and connected so that the plug is inserted into the mounting cavity along the guide groove.

[0015] Preferably, reinforcing ribs are provided at intervals on both sides of the positioning rib, and when the connector is inserted into the mounting cavity along the guide groove, the reinforcing ribs can abut against the inner wall of the sleeve.

[0016] Preferably, the sleeve is detachably connected to the upper housing.

[0017] The beneficial effects of this utility model are mainly reflected in the following: The handheld torch provided by this utility model, which is easy to assemble and disassemble, can ensure that the upper shell and the lower shell remain relatively fixed without the action of external force through the cooperation of the first and second locking parts, which will result in higher stability and connection reliability and less loosening; at the same time, it is also more convenient to assemble and disassemble, without the need for complicated operation steps.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] refer to Figure 1-10 This utility model provides a handheld torch that is easy to assemble and disassemble, including an upper shell 1 and a lower shell 2, which are detachably connected. A sleeve 10 is provided in the upper shell 1 near the lower shell 2 (the end near the lower shell 2 refers to the end where the upper shell 1 connects to the lower shell 2. Assuming the upper shell 1 has a top and a bottom, with the top serving as the torch's flame outlet and the bottom connecting to the lower shell 2), an mounting cavity 101 is formed in the sleeve 10, and a bottom opening is provided in the sleeve 10. An insertion port communicating with the mounting cavity 101 is provided at the end of the lower housing 2 near the upper housing 1, where a connector 20 is located (similarly, the end of the lower housing 2 near the upper housing 1 can also be understood as the top of the lower housing 2). The connector 20 can be inserted into the mounting cavity 101 through the insertion port and connected to the sleeve 10. An elastic member 3 is provided on the outer side of the sleeve 10. The elastic member 3 has a first locking part, and the connector 20 has a second locking part. When the connector 20 is inserted into the mounting cavity 101, the first locking part can cooperate with the second locking part to fix the upper housing 1 and the lower housing 2. The so-called fixation refers to a relatively fixed state, that is, the connection stability between the upper housing 1 and the lower housing 2 can be maintained without the action of external force, while the upper housing 1 and the lower housing 2 can be separated under the action of external force.

[0036] Specifically, the handheld torch provided by this utility model can be used by simply aligning the top of the lower housing 2 with the bottom of the upper housing 1, inserting the connector 20 into the receiving cavity inside the sleeve 10, and quickly installing and fixing the upper housing 1 and the lower housing 2 with the cooperation of the first and second locking parts. When it is necessary to disassemble the upper housing 1 and the lower housing 2, simply hold the upper housing 1 and the lower housing 2 respectively and apply force in opposite directions to pull the connector 20 out of the receiving cavity, and then store the upper housing 1 and the lower housing 2 respectively. The operation is simple and quick, greatly improving the efficiency of assembling and disassembling the handheld torch.

[0037] The handheld torch provided by this utility model, which is easy to assemble and disassemble, has the following advantages compared with the prior art:

[0038] This invention primarily achieves connection through the elastic element 3 and the snap-fit ​​part, resulting in a relatively simple structure and lower processing requirements compared to threaded connections. Furthermore, threaded connections are prone to thread damage due to wear and tear during long-term use, affecting the engagement between threads and potentially causing the torch to loosen. In contrast, this invention, under normal use, ensures that the upper housing 1 and lower housing 2 remain relatively fixed without external force, resulting in higher stability and connection reliability, and reducing the likelihood of loosening. Simultaneously, it is more convenient to assemble and disassemble, eliminating the need for cumbersome procedures.

[0039] refer to Figure 3 , 5 6. In a preferred embodiment, the elastic element 3 includes a mounting section 30 and a snap-fit ​​section 31 connected to each other. The snap-fit ​​section 31 is fixed to the sleeve 10 through the mounting section 30. That is, the main function of the mounting section 30 is to fix the elastic element 3 on the sleeve 10, providing support and connection. The snap-fit ​​section 31 is mainly the core component of the elastic element 3, used for snap-fit ​​fixing between the upper housing 1 and the lower housing 2. The first snap-fit ​​part is provided on the snap-fit ​​section 31. When the insert 20 is inserted into the mounting cavity 101, the first snap-fit ​​part can abut against the second snap-fit ​​part. When the insert 20 is connected to the sleeve 10, a slot 21 is formed to accommodate the snap-fit ​​section 31. The slot 21 provides a certain deformable space for the snap-fit ​​section 31. At least part of the snap-fit ​​section 31 abuts against the groove wall of the slot 21, so that the snap-fit ​​section 31 can undergo elastic deformation under the action of external force. Furthermore, multiple slots 21 and elastic elements 3 can be provided to improve the overall stability after the torch is inserted.

[0040] Specifically, the snap-fit ​​segment 31 serves as the main elastic deformation part of the elastic element 3, and a portion of the snap-fit ​​segment 31 abuts against the groove wall of the slot 21, as shown in the reference. Figure 3During installation, because part of the snap-fit ​​segment 31 abuts against the groove wall of the slot 21, when the connector 20 is inserted into the mounting cavity 101, the other part of the snap-fit ​​segment 31 is squeezed by the connector 20 and undergoes elastic deformation, so that the connector 20 can smoothly enter the mounting cavity 101. When the connector 20 is fully inserted into the mounting cavity 101, the snap-fit ​​segment 31 returns to its original shape under the action of elastic restoring force, so that the first snap-fit ​​part and the second snap-fit ​​part can abut against each other, realizing the fixed connection between the upper shell 1 and the lower shell 2.

[0041] refer to Figure 3 , 7 -10, In a further preferred embodiment, the connector 20 has a first groove 201, and the sleeve 10 has a second groove 102 opposite to the first groove 201 (opposite means that the openings of the two grooves are opposite to each other), see reference. Figure 3 When the connector 20 is inserted into the mounting cavity 101, the first groove 201 and the second groove 102 cooperate to form a slot 21; that is, when the connector 20 is inserted into the mounting cavity 101 of the sleeve 10, the first groove 201 and the second groove 102 cooperate to form a complete slot 21, which is used to accommodate the snap-fit ​​section 31 of the elastic member 3, so that it has a certain deformable space;

[0042] refer to Figure 3 The snap-fit ​​section 31 includes a bent edge 310, which is the first snap-fit ​​part; the second snap-fit ​​part is a boss 22, which is located at the top of the first groove 201 and extends outward along the radial direction of the first groove 201. The bent edge 310 can abut against the boss 22. During installation, as the connector 20 is inserted into the mounting cavity 101, it will compress the snap-fit ​​section 31, causing it to deform. When the connector 20 is inserted into place, the bent edge 310 will contact (abut against) the boss 22. At this time, the first groove 201 and the second groove 102 also cooperate to form a slot 21. The part of the elastic member 3 that is compressed at this time has a certain space in the slot 21. After the external force is removed, it returns to its original state, thereby making the bent edge 310 and the boss 22 abut against each other and not easy to loosen. When disassembly is required, simply pull the lower housing 2 outward with a little force to allow the connector 20 to detach from the mounting cavity 101, greatly improving the convenience of torch assembly and disassembly.

[0043] refer to Figure 3 , 56. In a preferred embodiment, the snap-fit ​​section 31 further includes a fixed edge 311 and an elastic compression edge 312. The bent edge 310, the fixed edge 311, and the elastic compression edge 312 can be integrally formed to improve the overall strength. The first end of the bent edge 310 is connected to the mounting section 30, the second end of the bent edge 310 is connected to the fixed edge 311, the other end of the fixed edge 311 is connected to the elastic compression edge 312, and the end of the elastic compression edge 312 extends away from the fixed edge 311 and connects with the second groove. The groove wall of the second groove 102 abuts against each other; as the end of the elastic compression edge 312 abuts against the groove wall of the second groove 102, it provides a relative support point for the elastic deformation of the entire elastic member 3. It is precisely because the end of the elastic compression edge 312 abuts against the groove wall of the second groove 102, and at the same time, a deformation space that can be elastically deformed in the radial direction is formed between the elastic compression edge 312 and the fixed edge 311, that the snap-fit ​​section 31 can undergo elastic deformation when the plug-in member 20 is inserted into the mounting cavity 101. In this embodiment, the fixed edge 311 serves as the connection between the bent edge 310 and the elastic compression edge 312, and in the actual installation process, it is also a part that is directly squeezed by the plug-in member 20.

[0044] refer to Figure 3 Specifically, during the insertion of the connector 20 into the mounting cavity 101, the outer wall of the connector 20 directly applies radial extrusion force to the fixed edge 311, causing the fixed edge 311 to be compressed (deformed) in the direction of the elastic compression edge 312. When the connector 20 continues to push upward until the bent edge 310 abuts against the boss 22, the fixed edge 311 loses the extrusion force under the clearance effect of the first groove 201, and thus returns to its original state under the action of elastic force.

[0045] refer to Figure 6 In a preferred embodiment, the bent edge 310 forms an angle with the horizontal line, the angle being 30°±5°. That is, the bent edge 310 has a certain inclination angle, which allows the connector 20 to have a guiding effect during insertion, while also reducing the resistance during insertion, ensuring smooth connection between the lower housing 2 and the upper housing 1. The angle between the bent edge 310 and the horizontal line is preferably 30°, but there may be some deviation in actual operation, such as 25° or 35°. In this embodiment, the horizontal line serves as a reference benchmark, mainly referring to a straight line perpendicular to the axis of the torch body. For example, when the torch is placed vertically, with its axis also vertical, the horizontal line is a straight line perpendicular to the vertical axis, and the angle between the bent edge 310 and the horizontal line refers to the angle between the bent edge 310 and this horizontal line (e.g., ...). Figure 6 The angle represented by α is the angle between the bent edge 310° and the horizontal line.

[0046] refer to Figure 6 In a preferred embodiment, the radial width of the deformation space in its natural state is 1-5 mm. In this embodiment, the deformation space refers to the gap formed between the elastic compression edge 312 and the fixed edge 311, which allows the elastic compression edge 312 to elastically deform when the connector 20 is inserted. The natural state refers to the state of the elastic compression edge 312 when it is not subjected to external force (i.e., when it is not compressed by the connector 20); the radial width refers to the deformation space in the radial direction (i.e.,...). Figure 6 The width of the elastic compression edge 312 in the left-right direction (or the direction perpendicular to the insertion of the connector 20) directly determines the degree of deformation that the elastic compression edge 312 can produce when subjected to external force. It can also be understood as the width distance between the end of the elastic compression edge 312 and the fixed edge 311 (i.e.,...). Figure 6 (D distance in the diagram). Therefore, the radial width of the deformation space in its natural state is controlled between 1-5 mm, specifically 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm. Too small a width may prevent the elastic compression edge 312 from deforming properly in the direction of the deformation space, resulting in excessive resistance or inability to insert the connector 20; while too large a width may lead to instability and loosening of the connection. Therefore, controlling the deformation space within a reasonable range ensures that the connector 20 can be smoothly inserted into the mounting cavity 101, while also ensuring the stability and reliability of the connection between the upper housing 1 and the lower housing 2.

[0047] refer to Figure 5 and 7 In a preferred embodiment, the elastic member 3 has a first positioning hole 32 extending through its thickness direction; the sleeve 10 has a second positioning hole 11 that mates with the first positioning hole 32; the first positioning hole 32 and the second positioning hole 11 are locked together by fasteners (e.g., pins) to fix the elastic member 3 to the sleeve 10.

[0048] refer to Figure 7-9 In a preferred embodiment, the sleeve 10 is further provided with a guide groove 12 extending along its axial direction, and the connector 20 is provided with a positioning rib 23 extending along its axial direction. The guide groove 12 and the positioning rib 23 are matched and connected so that the connector 20 is inserted into the mounting cavity 101 along the guide groove 12. During installation, the positioning rib 23 and the guide groove 12 form a guiding match, so that the connector 20 can be directly inserted into the mounting cavity 101 along the direction of the guide groove 12, avoiding misalignment between the sleeve 10 and the connector 20, and further improving the installation efficiency between the upper housing 1 and the lower housing 2. At the same time, another function of the guide groove 12 is to allow the sleeve 10 to have a certain expansion margin, thereby facilitating the insertion of the connector 20.

[0049] refer to Figure 9 In a further preferred embodiment, reinforcing ribs 24 are provided at intervals on both sides of the positioning rib 23. When the connector 20 is inserted into the mounting cavity 101 along the guide groove 12, the reinforcing ribs 24 can abut against the inner wall of the sleeve 10. During installation, the user can directly align the positioning rib 23 on the connector 20 with the guide groove 12 of the sleeve 10 and then insert it into the mounting cavity 101. By providing reinforcing ribs 24 on both sides of the positioning rib 23, when the connector 20 is inserted into the sleeve 10, the reinforcing ribs 24 can directly abut against the inner wall of the sleeve 10, thereby ensuring that the upper housing 1 and the lower housing 2 will not sway or loosen after installation.

[0050] In a preferred embodiment, the sleeve 10 is detachably connected to the upper housing 1. For example, the sleeve 10 and the upper housing 1 can be detachably connected by screws, which facilitates the maintenance and replacement of the sleeve 10, or makes it easier to remove the sleeve 10 and install other components inside the upper housing 1.

[0051] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
