[0051] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0053] like Figure 1 and Figure 2 As shown, the compact hot melt device provided in the embodiment of the present application includes a mounting shell 100, a hot melt assembly and a supporting and holding assembly. The interior of the mounting shell 100 is used to place wires or a thermostat, etc. The mounting shell 100 has a first end and a second end relative to each other. The hot melt assembly is connected to the first end of the mounting shell 100, and the hot melt assembly is configured to hot melt the plastic pipe to be connected.

[0054] The support and grip assembly includes a plurality of grip legs 300, each of which is connected to the mounting shell 100. The support and grip assembly has a gripping state (such as Figure 1 ) and support status (e.g. Figure 2), when the support grip assembly is in the gripping state, each gripping leg 300 is closed to form a grip for the user to hold. The user can hold the grip to pick up the hot melter. This state is suitable for situations where the user needs to hold the hot melter to weld pipe materials and store the hot melter. In this state, each gripping leg 300 is closed together to make the overall volume of the hot melter smaller, which is convenient for storage, and there is no problem that the folding bracket is easily lost due to being stored separately. When the support grip assembly is in the supporting state, each gripping leg 300 is separated to form a leg supporting the hot melter. The hot melter can be placed on the ground with the support of multiple gripping legs 300. In this state, the user's hand holding the hot melter can be freed, which is convenient for user operation.

[0055] The hot melt provided in the embodiment of the present application can be held or placed on the ground by changing the state of the supporting holding component, that is, the supporting holding component can be used as a handle for the user to hold when the holding legs 300 are closed, and can be used as a leg to support the hot melt when the holding legs 300 are separated. It is flexible to use, small and easy to hold, convenient for users to operate hot-melt butt-jointed pipes in a small space, easy to store, and does not have scattered parts or the problem of lost parts.

[0056] Exemplarily, in order to increase the strength of each holding leg 300 , a plurality of reinforcing ribs are disposed inside the holding leg 300 .

[0057] In some embodiments of the present application, Figure 1 and Figure 4 As shown, each gripping leg 300 includes a connecting portion 310 and a gripping portion 320 connected to each other, the connecting portion 310 is arranged around the mounting shell 100, and one end of the connecting portion 310 away from the gripping portion 320 is rotatably connected to the mounting shell 100. When the support gripping assembly is in the gripping state, two adjacent gripping portions 320 are spliced. In the embodiment of the present application, the splicing of two adjacent gripping portions 320 means that the adjacent gripping portions 320 are spliced ​​without a gap or with a small gap, and this setting can increase the comfort of the user holding the gripping portion 320.

[0058] like Figure 1 and Figure 3As shown, the mounting shell 100 includes a first portion 110, a second portion 120 and a third portion 130 connected in sequence, the first portion 110, the second portion 120 and the third portion 130 form a three-level stepped structure, a hot melt assembly is arranged at one end of the first portion 110 away from the second portion 120, and the second portion 120 and the third portion 130 are provided with a receiving groove 140 corresponding to each connecting portion 310, in the corresponding receiving groove 140 and the connecting portion 310, the connecting portion 310 is placed in the receiving groove 140, and one end of the connecting portion 310 away from the gripping portion 320 is rotatably connected to the side wall of the receiving groove 140 located on the second portion 120. When the supporting gripping assembly is in the gripping state, a plurality of connecting portions 310 cooperate to wrap the third portion 130, and the outer surfaces of the plurality of connecting portions 310 are spliced ​​with the outer surface of the second portion 120, that is, the radial dimensions of the first portion 110, the second portion 120 and the third portion 130 are sequentially reduced. This arrangement enables the connecting portion 310, the second portion 120 and the third portion 130 to form a smooth outer surface when the supporting holding assembly is in the holding state, i.e. when the connecting portion 310 is placed in the accommodating groove 140. This arrangement can increase the aesthetics of the hot melter, and the fewer edges and corners can reduce dust accumulation.

[0059] In this embodiment, if Figure 1 As shown, the outer surfaces of the multiple connecting parts 310 are spliced ​​with the outer surface of the second part 120 to form a first cylindrical structure, and the multiple gripping parts 320 are spliced ​​to form a second cylindrical structure, and the radial dimension of the second cylindrical structure is smaller than the radial dimension of the first cylindrical structure. In other words, the second part 120 and the third part 130 are formed by stacking two cylinders with different radial dimensions (which can be integrally formed) and opening a receiving groove 140, and the multiple gripping parts 320 are spliced ​​to form a second cylindrical structure for the convenience of users to hold, and the outer surfaces of the multiple connecting parts 310 are spliced ​​with the outer surface of the second part 120 to form a first cylindrical structure, and the first cylindrical structure is the same as the second cylindrical structure, which is convenient for processing and makes the overall appearance more beautiful.

[0060] See also Figure 1 and Figure 3 In some embodiments of the present application, the hot melt assembly includes a hot melt plate 200 and a hot melt die set (not shown in the figure), and the hot melt die set is connected to the hot melt plate 200 in the length direction (such as Figure 1 The first portion 110 has a first plane 111, a second plane 112, a third plane and a fourth plane. The first plane 111 and the third plane are located in the thickness direction of the hot melt plate 200 (eg, Figure 1 The first plane 111 and the third plane are both tangent to the first cylindrical structure, and the second plane 112 and the fourth plane are located in the width direction of the hot melt plate 200 (such as Figure 1 The second plane 112 is flush with one side of the hot melt plate 200 in the width direction, and the fourth plane is flush with the other side of the hot melt plate 200 in the width direction. This setting cuts flat both sides of the first part 110 in the thickness direction of the hot melt plate 200, and both sides of the first part 110 in the width direction of the hot melt plate 200, so that the size of the hot melt device in the thickness direction of the hot melt plate 200 is reduced to the same as the radial size of the first cylindrical structure, and the size in the width direction of the hot melt plate 200 is reduced to the same as the width of the hot melt plate 200. This setting makes the hot melt device in the embodiment of the present application smaller in the width direction and thickness direction of the hot melt plate 200, which is convenient for users to hold the hot melt device and extend it into a relatively narrow space for operation, and is more flexible to use. In addition, the first plane 111, the second plane 112, the third plane and the fourth plane can be used as reference planes and attached to the wall and other locations for user operation.

[0061] Exemplarily, in some embodiments of the present application, there are multiple hot melt die head groups, each hot melt die head group includes a matching first hot melt die head and a second hot melt die head, and each hot melt die head group is applicable to different sizes of plastic pipes to be butted, that is, each hot melt die head group includes a matching first hot melt die head and a second hot melt die head, the radial sizes of the first hot melt die head and the second hot melt die head are different, the first hot melt die head is used to heat the first pipe section, and the second hot melt die head is used to heat the second pipe section butted with the first pipe section, and different hot melt die head groups are applicable to hot melt butt plastic pipes of different models and sizes. In order to reduce the length of the hot melt plate 200, and then reduce the overall length of the hot melt, so that the hot melt is more compact, a hot melt die head group installation site is set on the hot melt plate 200, and any hot melt die head group can be detachably connected to the hot melt die head group installation site. That is to say, users can replace the hot melt die head group according to needs to adapt to the hot melt butt joint of plastic pipes of different sizes. This setting enables the hot melter to be suitable for hot melt butt joint of plastic pipes of different sizes on a small basis, and has a wide range of applications.

[0062] In some embodiments of the present application, in the corresponding accommodating groove 140 and the connecting portion 310, a first clamping portion is provided on the connecting portion 310, and a second clamping portion 141 is provided in the accommodating groove 140 corresponding to the first clamping portion, and the first clamping portion and the second clamping portion 141 are engaged with each other to limit the position of the connecting portion 310. This arrangement enables the support grip assembly to be in the gripping state, and each gripping leg 300 is engaged with the second clamping portion 141 through the first clamping portion, so that each gripping leg 300 will not shake or rotate at will, and is convenient for the user to hold.

[0063] For example, Figure 3 As shown, the second clamping portion 141 is a clamping slot, and correspondingly, the first clamping portion is a buckle.

[0064] For example, Figure 3 and Figure 4 As shown, in the corresponding accommodating groove 140 and connecting portion 310, a limiting inclined surface 330 is provided at one end of the connecting portion 310 away from the gripping portion 320, and the side wall of the accommodating groove 140 close to the first portion 110 is a limiting wall surface 142, and the limiting inclined surface 330 cooperates with the limiting wall surface 142 to limit the position of the gripping leg 300. In other words, when the support gripping assembly is in the supporting state, the limiting wall surface 142 cooperates with the limiting inclined surface 330, and the limiting wall surface 142 blocks the gripping leg 300 from continuing to rotate, thereby achieving that each gripping leg 300 is supported on the ground.

[0065] In some embodiments of the present application, Figure 1 and Figure 2 As shown, in order to limit the position of each holding leg 300 after closing and reduce the gap between two adjacent holding legs 300, the hot melt device also includes a binding head 400, which is detachably mounted on the handle, and the binding head 400 is configured to bind the spliced ​​holding portion 320. The binding head 400 is mounted on the spliced ​​holding portion 320 to clamp the spliced ​​holding portion 320 to avoid a gap between two adjacent holding legs 300.

[0066] Exemplarily, the tie head 400 is made of soft rubber material.

[0067] Please continue reading Figure 1 and Figure 2 The hot melt device further includes a power line 500, which is electrically connected to the hot melt assembly. The power line 500 extends from the second end of the mounting shell 100, and the power line 500 passes through the internal space of the grip and extends from the end of the grip away from the mounting shell 100. The tie head 400 is sleeved on the power line 500 and can move on the power line 500. The end of the power line 500 extending from the grip is provided with a power plug, and the power plug blocks the tie head 400 from moving out of the power line 500. This setting can limit the position of the tie head 400, so that the tie head 400 can only move on the power line 500, and can prevent the tie head 400 from being lost.

[0068] It should be noted that the hot melt device of the embodiment of the present application may not be provided with a power transmission line 500 , and it can be powered by a battery provided in the mounting shell 100 .

[0069] like Figure 1 and Figure 2 As shown, in some embodiments of the present application, there are three holding legs 300, and when the holding assembly is in the supporting state, the supporting points of the three holding legs 300 enclose an equilateral triangle. In other words, the supporting points of the three holding legs 300 are connected in sequence to form an equilateral triangle, and this arrangement can support the hot melter higher and more stably.
