Description

Technical Field

[0001] The utility model relates to the technical field of outdoor products, in particular to a folding shovel. Background Art

[0002] The shovel has been improved to fold twice after the third generation of engineer shovels. Most of the handles are triangular streamlined in shape, and the shovel has the functions of shovel, pickaxe, crowbar, saw, knife, etc. In order to further reduce the storage space, the current shovel will adopt a three-fold structure. For example, patent No. CN201921215003.1 discloses a new folding shovel, which is composed of a shovel head, an intermediate connecting rod body and a handle. The shovel head and the handle are respectively supported and fixed by the outer sheath of the intermediate connecting rod body and the locking knob threaded connection. However, when unfolding, when it is taken horizontally, because both hands hold the sheath and the locking knob to stretch and unfold, the shovel head and the handle are hinged with the intermediate connecting rod body, causing the shovel head and the handle to rotate due to gravity. The whole shovel must be taken vertically or the handle must be clamped first and then the sheath and the locking knob are rotated, which causes inconvenience when used. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a folding shovel, which has a simple structure and is more convenient to operate.

[0004] In order to solve the above problems, the utility model adopts the following technical solutions:

[0005] A folding shovel comprises a handle, a shovel head and a connecting rod, wherein the left and right ends of the connecting rod are respectively hinged to the handle and the shovel head, a sheath is sleeved on the connecting rod, a tension knob is threadedly connected to the sheath near the handle side, a limit rod is fixed on the connecting rod, at least one spring is placed in the sheath, one end of the spring abuts against the limit rod, and the other end abuts against the side end of the sheath near the handle.

[0006] A further technical solution is that the limit rod passes through the connecting rod in the horizontal front-to-back position, and two springs are provided, one end of the two springs abuts against the limit rod, and the other end abuts against the side end of the sheath close to the handle, and the two springs have stronger rebound force.

[0007] A further technical solution is that the left and right ends of the connecting rod are respectively connected to the handle and the shovel head connecting piece at the hinge, so that the left and right ends of the connecting rod are respectively limited by the handle and the shovel head connecting piece and can be rotatably connected.

[0008] A further technical solution is that threads are distributed on the circumferential side of the inner wall of the tension knob and on the outer circumferential side where the sleeve is threadedly connected to the tension knob for threaded tension connection.

[0009] A further technical solution is that one or more limit plates are distributed on the left and right ends of the inner side of the sheath, and a movable cavity is formed between the two limit plates. The spring can be placed in the movable cavity to limit its displacement.

[0010] A further technical solution is that the outer circumferential surface of the tension knob is also distributed with anti-slip teeth to prevent slipping when gripping.

[0011] The beneficial effects of the utility model are as follows: the utility model is a folding shovel, a limit rod is installed on the connecting rod, and a spring is placed in the sheath at the front and rear ends between the limit rod and the sheath. When the shovel is unfolded, the spring resets to make the sheath push toward the handle, so that when one hand holds the tension knob and the other hand rotates the sheath for limiting, the handle cannot be restricted and causes rotation. When unfolding, both hands hold the sheath tension knob and rotate them to hold the handle and the shovel head, which is more convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] See also Figures 1 to 9 As shown, a folding shovel comprises a handle 1, a shovel head 7 and a connecting rod 5, wherein the left and right ends of the connecting rod 5 are hinged to the handle 1 and the shovel head 7 respectively, a sheath 4 is sleeved on the connecting rod 5, a tension knob 3 is threadedly connected to the sheath 4 near the handle 1 side, a limit rod 9 is fixed on the connecting rod 5, at least one spring 8 is placed in the sheath 4, one end of the spring 8 abuts against the limit rod 9, and the other end abuts against the side end of the sheath 4 near the handle 1.

[0025] The limit rod 9 passes through the connecting rod 5 along the horizontal front and rear positions, and two springs 8 are provided. One end of the two springs 8 both abuts on the limit rod 9, and the other end abuts on the side end of the sheath 4 close to the handle 1. The two springs 8 have more resilience. The left and right ends of the connecting rod 5 are respectively connected to the handle 1 and the shovel head connecting piece 6 at the hinge, so that the left and right ends of the connecting rod 5 are respectively limited by the handle 1 and the shovel head connecting piece 6 and can be rotatably connected. The inner wall circumferential side of the tension knob 3 and the outer circumferential side of the sheath 4 and the tension knob 3 are threadedly connected. There are threads 12 for threaded tension connection. There are more than one limit plate 10 on the left and right ends of the inner side of the sheath 4, and an active cavity 11 is formed between the two limit plates 10. The spring 8 can be placed in the active cavity 11 to limit its displacement. Anti-slip teeth 13 are also distributed on the outer circumferential surface of the tension knob 3, which can prevent slipping when gripped.

[0026] In this embodiment, if Fig. 9 The figure shows a schematic diagram of the three-stage folding state. When it is needed, the handle 1 and the shovel head 7 are reset clockwise. At this time, since two springs 8 are placed inside the sheath 4, the two springs 8 are reset when unfolded, so that the tension knob 3 on the sheath 4 is pressed against the handle 1 due to the elastic force of the two springs 8. At the same time, the tension knob 3 is held by the hand, and then the sheath 4 is rotated. The tension knob 3 rotates on the sheath 4. After rotation, the tension knob 3 is displaced on the sheath 4 to make the left and right ends longer. Finally, the right end of the sheath 4 presses against the shovel head 7. When folded, as shown in FIG. Figure 1-4As shown, the handle 1 rotates counterclockwise, and the shovel head 7 also rotates counterclockwise. At this time, the spring 8 is in a compressed state, and the entire folding shovel is in a three-folded state.

[0027] The above embodiment is only an example of the present invention and is not intended to limit the implementation and scope of rights of the present invention. Any technical solution that is identical or equivalent to the content described in the claims of the present invention should be included in the protection scope of the present invention.
