Description
Technical Field
[0001] The utility model relates to the technical field of tent fixing, in particular to a novel crowbar structure. Background Art
[0002] In outdoor emergency situations, field military training and other occasions, the installation of large tents is often involved. Large tents, such as large air rib tents, are different from small family tents. Their ground stakes (ground nails) are required to bear greater forces in design and installation. When pulling out the ground stakes (ground nails), it is difficult to pull out the ground stakes (ground nails) quickly manually, so auxiliary tools are often used for pulling out the nails.
[0003] Most of the auxiliary tools currently used are conventional crowbars, which are generally light and simple in structure and have poor use effects. There are also schemes in the prior art to improve the structure of the crowbar, such as CN105060203A, CN205367633U, etc. The improvement focus of these schemes is more on optimizing the crowbar in moving heavy objects, rather than optimizing the nail pulling.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0038] like Figures 1 to 9 As shown, this embodiment provides a new type of crowbar structure, including a crowbar grip 2, a crowbar base 1 and a crowbar support pad 3. The crowbar base 1 is mainly used to contact the ground for support, the crowbar grip 2 is mainly used for operators to apply force, and the crowbar support pad 3 is mainly used to be installed at the bottom of the crowbar base for auxiliary support.
[0039] The above components are introduced in detail below.
[0040] The crowbar handle 2 is made of round steel to ensure the strength required for use. The crowbar handle 2 is a segmented structure, including a head handle 21 and a tail handle 22, and the front end of the tail handle 22 is detachably fixedly connected to the tail of the head handle 21.
[0041] Specifically, a slot is provided at the rear of the head grip 21, and a plug-in portion that matches the slot is provided at the front end of the tail grip 22. A transverse spring limit top block 23 (the spring limit top block 23 has a similar structure to the spring pin) is symmetrically provided on the plug-in portion of the tail grip, and a plug hole that matches the spring limit top block is provided on the slot of the head grip 21. When connected, the plug-in portion of the tail grip 22 can be inserted into the slot of the head grip 21 and fixed by the spring limit top block 23, thereby realizing a detachable fixed connection between the tail grip 22 and the head grip 21.
[0042] During the use of the crowbar grip, in order to facilitate the operator to apply force and prevent the palm from sweating and slipping, a sheath 20 is installed at the rear of the tail grip 22. The sheath 20 is made of a heat shrink tube. The heat shrink tube is put on the grip and heated to achieve close contact between the heat shrink tube and the surface of the grip. The processing is simple, economical and practical.
[0043] The crowbar base 1 includes a flat base body, which is manufactured by a whole-plate integrated machine, thereby improving the processing quality and precision. At the same time, a weight-reducing streamlined design is adopted, and unused positions on the base body are removed without affecting the use.
[0044] The front part of the base body is provided with a nailing area 10, which is a V-shaped notch structure, so that the prying position of the crowbar can use ground piles (ground nails) 4 of different sizes, thereby improving the adaptability of the crowbar.
[0045] A connecting seat is fixedly provided on the upper rear side of the base body, and the connecting seat is used to connect with the head of the head grip rod 21.
[0046] Specifically, the connecting seat includes two first mounting ears 11 fixed on the base body and arranged opposite to each other on the left and right. A second mounting ear 24 is fixed to the head of the head handle. The second mounting ear 24 is located between the two first mounting ears 11 and is connected through a fixed pin shaft, thereby realizing the connection between the crowbar handle 2 and the crowbar base 1.
[0047] An angle switching mechanism is also provided between the base body and the crowbar handle 2. The angle switching mechanism includes angle switching component 1 and angle switching component 2. Angle switching component 1 is installed on the base body, and angle switching component 2 is installed on the crowbar handle 2. Angle switching component 1 and angle switching component 2 cooperate to realize the angle switching of the crowbar handle relative to the crowbar base.
[0048] The specific settings of the angle switching mechanism are as follows:
[0049] Two tooth plates 12 are fixedly arranged on the upper rear side of the base body, and the two tooth plates 12 are located on the outer sides of the two first mounting ears 11. The tooth plate 12 is provided with a plurality of teeth, and positioning notches are formed between the teeth, and the center of the circle corresponding to the teeth is colinear with the center of the fixed pin shaft, thereby forming an angle switching component 1.
[0050] A limiting plate 25 extending left and right is fixed to the front end of the tail handle 22, and the limiting plate 25 is snap-fitted with the positioning notch to form the second angle switching component.
[0051] The working principle of the angle switching mechanism is as follows: first press the spring limit top block 23 to retract it, then pull the plug-in part of the tail grip 22 upward by one end until the limit plate 25 is disengaged from the teeth, then rotate and adjust the angle of the head grip around the fixed pin shaft, and then reinsert the plug-in part of the tail grip into the slot of the head grip 21 after it is adjusted to the right position, and at the same time the spring limit top block 23 is reset to complete the fixation, and at this time the limit plate 25 is aligned with the positioning notch of the corresponding angle and forms a snap fit, thereby completing the angle switching of the crowbar grip 2 relative to the crowbar base 1. This design makes it easy for operators to select a suitable angle to apply force, which is convenient for nail removal.
[0052] The crowbar support pad 3 is arranged on the lower side of the base body, and the crowbar support pad 3 and the lower side of the base body form an adjustable locking fixation in the front-to-back direction, which can realize auxiliary support at different positions and improve the adaptability of the crowbar on different ground surfaces.
[0053] Specifically, two groups of slideways 31 extending in the front-rear direction are provided on the lower side of the base body, and two protrusions are correspondingly provided on the crowbar support pad 3. The protrusions are slidably connected to the slideways 31, so that the crowbar support pad 3 can slide in the slideways 31 to adjust its position.
[0054] A row of fixing holes 32 are provided on each side of the slideway 31 in parallel therewith. The fixing holes 32 can not only play the role of connecting the crowbar support pad 3 through bolts, but also can be used for weight reduction design.
[0055] Two connecting holes 33 are respectively provided on the left and right sides of the crowbar support pad 3 , through which bolts pass, and bolts 34 pass through corresponding fixing holes at the same time, so as to fix the position of the crowbar support pad 3 .
[0056] The utility model designs the crowbar structure. On the basis of increasing the overall structural strength of the crowbar, a lightweight structure design is carried out from the perspective of ergonomics. At the same time, the angle of the crowbar grip can be adjusted according to the angle and strength of the operator's operation, which is convenient for the operator to select a suitable angle to apply force and convenient for the operator to use, thereby being able to play a good nail removing function and improving the construction efficiency of the operator.
[0057] The crowbar structure of the utility model can be used on sand and hard soil, and can quickly and effectively pull out the ground pile from the ground. During the pile pulling process, the ground pile (ground nail) 4 is clamped through the V-shaped notch on the crowbar base 1. During the pulling process, the crowbar support pad 3 on the lower side of the crowbar base 1 can play a role in supporting the lifting. The ground pile (ground nail) 4 performs autonomous adaptive adjustment in the V-shaped notch during the pulling process, ensuring that the crowbar can steadily pull out the ground pile screw.
