Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building construction, and in particular provides a temporary gate bolt for construction sites. Background Technology
[0002] During construction, temporary gate bolts at construction sites are usually manually pushed in and pulled out. This method has two drawbacks: first, the bolts tend to rust and get stuck over time, which is time-consuming and laborious; second, it is easy to forget to push the bolt back in after pulling it out, which can lead to theft and property loss at the construction site. Utility Model Content
[0003] The purpose of this utility model is to provide a temporary gate bolt for construction sites, which solves the problem of bolts rusting and getting stuck, saves time and effort, and also avoids property damage at the construction site caused by forgetting to push the bolt in.
[0004] This utility model involves welding the bolt plate and fixing seat to the joint of the right and left door panels of the gate at the construction site. Then, by pulling the handle backward, the push-pull rod leaves the bolt plate, and the gate opens. After closing the gate, simply release the handle, and the push-pull rod will automatically spring back through the bolt plate, closing and locking the gate.
[0005] This utility model includes an insert plate 1, a front rib plate 2, a fixing base 3, a handle 4, a washer 5, a push-pull rod 6, a spring 7, and a rear rib plate 8, which are used in combination. The front rib plate 2 is vertically welded to the front end of the fixing base 3; the rear rib plate 8 is vertically welded to the rear end of the fixing base 3; the rear end of the spring 7 is vertically welded to the middle of the rear rib plate 8; the front end of the push-pull rod 6 passes through the middle of the front rib plate 2 and the insert plate 1, and can move left and right; the rear end of the push-pull rod 6 is inserted into the spring 7; the handle 4 passes vertically through the washer 5 and a rectangular notch on the top plate of the fixing base 3, and can move back and forth in the rectangular notch; the lower end of the handle 4 is vertically welded to the push-pull rod 6; the handle 4 is welded to the washer 5 (see...). Figure 1 , Figure 2 ).
[0006] Among them, the insert plate 1 is made of equilateral right-angle steel with a cross-sectional dimension of 80mm and a length of 100mm; the front rib plate 2 is made of 14mm thick steel plate and has dimensions of (length × width) 85 × 85mm; the fixing seat 3 is made of equilateral right-angle steel with a cross-sectional dimension of 100mm and a length of 200mm, with a rectangular notch on the fixing seat 3, the notch dimensions of (length × width) 150 × 20mm; the handle 4 is made of 14mm diameter round steel and has a length of 100mm; the washer 5 is a circular plate made of 8mm thick steel plate, with an outer diameter of 30mm and an inner diameter of 14mm; the push-pull rod 6 is made of 18mm diameter round steel and has a length of 160mm; the spring 7 is a purchased finished product, with an outer diameter of 26mm, an inner diameter of 20mm, and a length of 180mm in its natural state; the rear rib plate 8 is made of 14mm thick steel plate and has dimensions of (length × width) 85 × 85mm.
[0007] In use, weld the bolt insert plate 1 and the fixing seat 3 to the joint of the right door leaf 9 and the left door leaf 10 of the gate at the construction site, respectively. Then pull the handle 4 backward so that the push-pull rod 6 can move in the rectangular hole on the fixing seat 3. The push-pull rod 6 leaves the insert plate 1, and the gate opens. After closing the gate, simply release the handle 4, and the push-pull rod 6 will automatically spring back through the insert plate 1, and the gate will close and lock. Figure 3 , Figure 4 ).
[0008] The advantages of this utility model are that it is easy to assemble, easy to operate, simple and practical, solves the problem of door bolts rusting and getting stuck, saves time and effort, and also avoids property damage at the construction site caused by forgetting to push the door bolt.

[0014] Figures 1-4 This is one specific embodiment of the present invention. The present invention will be further described below with reference to the accompanying drawings.
[0015] This utility model includes a insert plate 1, a front rib plate 2, a fixing base 3, a handle 4, a washer 5, a push-pull rod 6, a spring 7, and a rear rib plate 8, which are used in combination. The front rib plate 2 is vertically welded to the front end of the fixing base 3; the rear rib plate 8 is vertically welded to the rear end of the fixing base 3; the rear end of the spring 7 is vertically welded to the middle of the rear rib plate 8; the front end of the push-pull rod 6 passes through the middle of the front rib plate 2 and the insert plate 1 respectively, and can move left and right; the rear end of the push-pull rod 6 is inserted into the spring 7; the handle 4 passes vertically through the washer 5 and a rectangular notch on the top plate of the fixing base 3, and the handle 4 can move back and forth in the rectangular notch; the lower end of the handle 4 is vertically welded to the push-pull rod 6; the handle 4 is welded to the washer 5.
[0016] In use, the bolt insert plate 1 and the fixing seat 3 are welded to the joint of the right door leaf 9 and the left door leaf 10 of the gate at the construction site, respectively. Then, pull the handle 4 backward so that the push-pull rod 6 can move in the rectangular hole on the fixing seat 3. The push-pull rod 6 leaves the insert plate 1, the gate opens, and after closing the gate, simply release the handle 4, and the push-pull rod 6 will automatically spring back through the insert plate 1, and the gate will close and lock.
[0017] During construction, a temporary door bolt was used for temporary gates at the construction site, achieving good results. This bolt is a combination of components: a front rib plate is vertically welded to the front end of the mounting base; a rear rib plate is vertically welded to the rear end of the mounting base; the rear end of a spring is vertically welded to the middle of the rear rib plate; the front end of a push-pull rod passes through the middle of the front rib plate and the insert plate, allowing it to move left and right; the rear end of the push-pull rod is inserted into the spring; the handle passes vertically through a washer and a rectangular notch on the top plate of the mounting base, allowing it to move back and forth within the notch; the lower end of the handle is vertically welded to the push-pull rod; the handle is also welded to the washer. In use, the insert plate and mounting base of the bolt are welded to the joint between the right and left doors of the gate at the construction site. Pulling the handle backward allows the push-pull rod to move through the rectangular hole on the mounting base, disengaging from the insert plate and opening the gate. After closing the gate, simply releasing the handle causes the push-pull rod to automatically spring back through the insert plate, locking the gate. This bolt is easy to assemble and operate, and is simple and practical. It solves the problem of bolts getting stuck due to rust, saves time and effort, and also avoids property damage at the construction site caused by forgetting to push the bolt in.
